(AP) ? As the world braced for a provocative missile launch by North Korea, with newscasts worldwide playing up tensions on the Korean Peninsula, the center of the storm was strangely calm.

The focus in Pyongyang was less on preparing for war and more on beautifying the city ahead of the nation's biggest holiday: the April 15 birthday of the nation's founder, Kim Il Sung. Soldiers put down their rifles to blanket the barren ground with sod and students picked up shovels to help plant trees.

But an impoverished, tightly controlled nation that has historically used major holidays to draw the world's attention by showing off its military power could well mark the occasion by testing a missile designed to strike U.S. military installations in Japan and Guam. South Korea's foreign minister said the prospect of a medium-range missile launch is "considerably high."

North Korean officials have not announced plans to launch a missile in defiance of U.N. Security Council resolutions barring Pyongyang from nuclear and missile activity.

But they have told foreign diplomats in Pyongyang that they will not be able to guarantee their safety starting Wednesday and urged tourists in South Korea to take cover, warning that a nuclear war is imminent. However, most diplomats and foreign residents in both capitals appeared to be staying put.

The European Union said there was no need for member states to evacuate or relocate their diplomatic missions, but called on North Korea to "refrain from further provocative declarations or action."

The threats are largely seen as rhetoric and an attempt by North Korea to scare foreigners into pressing their governments to pressure Washington and Seoul to change their policies toward Pyongyang, as well as to boost the military credentials of North Korea's young leader, Kim Jong Un. North Korea does not have diplomatic relations with the U.S. and South Korea, its foes during the Korean War of the 1950s, and has pushed for a peace treaty to replace a 60-year-old armistice.

On the streets of Pyongyang, there was no sense of panic.

Downtown, schoolchildren marched toward the towering statues of the two late leaders, Kim Il Sung and Kim Jong Il, dragging brooms to sweep the hilltop plaza where they lord over Pyongyang. Women with coats thrown over traditional dresses rushed through the spring chill after leaving a rehearsal for a dance planned for Kim Il Sung's birthday celebrations.

At the base of Mansu Hill, a group of young people held a small rally to pledge their loyalty to Kim Jong Un and to sing the Kim ode "We Will Defend the Marshal With Our Lives."

Kim Un Chol, the 40-year-old head of a political unit at Pyongyang's tobacco factory, said he had been discharged from the military but was willing to re-enlist if war breaks out. He said North Koreans were resolute.

"The people of Pyongyang are confident. They know we can win any war," he told The Associated Press. "We now have nuclear weapons. So you won't see any worry on people's faces, even if the situation is tense."

Kim Jong Il elevated the military's role during his 17-year rule under a policy of "military first," and the government devotes a significant chunk of its annual budget to defense. Human rights groups say the massive spending on the military and on development of missile and nuclear technology comes at the expense of most of its 24 million people. Two-thirds of the population face chronic food shortages, according to the World Food Program.

North Koreans are taught from childhood to hate the U.S. and to gird against an invasion by "imperialists" intent on taking over the entire Korean Peninsula.

Guns and tanks are popular toys for children in the highly militarized society, and young North Koreans learn to fire guns when they are teenagers, residents say. As young adults, they attend camps to learn military techniques.

But there was no sign North Koreans were brushing up on their skills Wednesday. Pyongyang sporadically holds civil air raid drills during which citizens practice blacking out their windows and seeking shelter. But no such drills have been held in recent months, local residents said.

Last year, the days surrounding the centennial of the birth of Kim Il Sung, grandfather of the current ruler, were marked by parades of tanks, goose-stepping soldiers and missiles, as well as the failed launch of a satellite-carrying rocket widely believed by the U.S. and its allies in the West to be a test of ballistic missile technology.

A subsequent test in December went off successfully, and that was followed by the country's third underground nuclear test on Feb. 12 this year, possibly taking the regime closer to mastering the technology for mounting an atomic bomb on a missile.

Last week, Kim Jong Un enshrined the pursuit of nuclear weapons ? which the North characterizes as a defense against the U.S. ? as a national goal, along with improving the economy. North Korea also declared it would restart a mothballed nuclear complex.

The resulting U.N. sanctions and this spring's annual U.S.-South Korean military drills, which Pyongyang sees as a rehearsal for invasion, have been met with an unending string of threats and provocations from the North. Washington denies it has any plans to invade, and calls the exercises routine defensive drills.

Adm. Samuel Locklear, commander of U.S. Pacific Command, told the Senate Armed Services Committee in Washington on Tuesday that North Korea's persistent nuclear and missile programs and threats have created "an environment marked by the potential for miscalculation."

He said the U.S. military and its allies would be ready if North Korea tries to strike.

Citing the tensions, North Korea on Monday pulled more than 50,000 workers from the Kaesong industrial park, which combines South Korean technology and know-how with cheap North Korean labor. It was the first time that production was stopped at the decade-old factory park, the only remaining symbol of economic cooperation between the Koreas.

In Seoul, South Korean Foreign Minister Yun Byung-se told lawmakers the North Korean missile is expected to have a range of about 3,500 kilometers (2,180 miles).

A Defense Ministry official told the AP preparations appeared to be complete, and that the launch could take place at any time. He spoke on condition of anonymity, saying he wasn't authorized to speak to the media.

The missile, dubbed "Musudan" by foreign experts after the name of the northeastern village where North Korea has a launch pad, is mainly designed to reach the U.S. territory of Guam though it can also place U.S. military installations in Japan in its striking range, experts said.

As a precaution, Japan has deployed PAC-3 missile interceptors in key locations around Tokyo while the South Korean and U.S. militaries have raised their level of surveillance.

The International Civil Aviation Organization said Wednesday it has received no notice of a missile launch from North Korea, but that it is not mandatory for Pyongyang to inform the organization. North Korea has worked with ICAO in the past to notify air traffic authorities in other countries of its plans to launch rockets.

In London, Russian Foreign Minister urged a calm response from all.

"You should not scare anyone with military maneuvers," he said, speaking in Russian, before sitting down for a meeting with U.S. Secretary of State John Kerry. "And then there's a chance everything can calm down."

One historian, James Person, noted that it isn't the first time North Korea has warned that a war was imminent.

He said that in 1968, following North Korea's seizure of an American ship, the USS Pueblo, Pyongyang persistently advised foreign diplomats to prepare for a U.S. counterattack. Cables from the Romanian mission in Pyongyang showed embassies were instructed to build anti-air bunkers "to protect foreigners against air attacks," he said.

The cables were obtained and posted online by the Wilson Center's North Korea International Documentation Project.

Person called it one of North Korea's first forays into what he calls "military adventurism."

"In 1968, there was some concern there would be an attack, but (the North Koreans) certainly were building it up to be more than it was in hopes of getting more assistance from their allies at the time," Person said by phone from Alexandria, Virginia.

"I think much of it was hot air then. Today, I think again, it's more hot air," he said. "The idea is to scare people into pressuring the United States to return to negotiations with North Korea. That's the bottom line."

NEW ORLEANS, April 9, 2013 Fundamental changes are needed in the education of the scientists whose work impacts medicine, drug discovery, development of sustainable new fuels and other global challenges society is facing in the 21st century. Those changes in graduate education in chemistry are the topic of a special symposium here today at the 245th National Meeting & Exposition of the American Chemical Society, the worlds largest scientific society.

The speakers will discuss results of one of the most comprehensive reports on graduate education in chemistry and the next steps in implementing its recommendations. The report, Advancing Graduate Education in the Chemical Sciences, resulted from a year-long project of an ACS presidential commission.

Although it concluded that the state of graduate education in the chemical sciences is productive and healthy in many respects, it found that the education of doctoral-level scientists has not kept pace with major changes in the global economic, social and political environment that have occurred since World War II, when the current system of graduate education took shape.

Bassam Z. Shakhashiri, Ph.D., convened the panel, the Commission on Graduate Education in the Chemical Sciences, as one of his major initiatives as 2012 ACS president. The William T. Evjue distinguished chair for the Wisconsin Idea at the University of Wisconsin-Madison, Shakhashiri organized and moderated the symposium. More information about the presentations in the symposium appears at the end of this release.

"The time for a close look at the education of tomorrow's scientists in this key discipline was long overdue," said Shakhashiri. "We hope the Commission's work will create the best possible experience for future scientists upon whom society will depend so heavily to address the great global challenges facing us all. They include climate change, population growth, finite resources, malnutrition, spreading disease and water management."

The Commission found that:

  • Current educational opportunities for graduate students, viewed on balance as a system, do not provide sufficient preparation for their careers after graduate school.
  • The system for the financial support of graduate students, as currently operated by private, institutional, state and federal funds, is no longer optimal for national needs.
  • Academic chemical laboratories must adopt best safety practices. Such practices have led to a remarkably good record of safety in the chemical industry and should be leveraged.
  • Departments should give thoughtful attention to maintaining a sustainable relationship between the availability of new graduates at all degree levels and genuine opportunities for them. Replication in excess is wasteful of resources and does injustice to the investment made by students and society.
  • Postdoctoral training and education is an extension of graduate education that is important for success in a variety of career paths, particularly for faculty appointments. Postdoctoral associates should be treated as the professional scientists and engineers they are. A postdoctoral appointment should be a period of accelerated professional growth that, by design, enhances scientific independence and future career opportunities.

The Commission developed its recommendations to address several fundamental concerns. Graduate programs, for instance, must prepare Ph.D. candidates for the present and future marketplace of opportunity. Second, the globalization of science necessitates stronger communication skills across disciplinary and cultural lines. Third, as many nations worldwide have greatly strengthened their scientific capacity by building universities and developing new businesses and markets, it is essential for the U.S. to engage more women and students from underrepresented populations to revitalize the chemical enterprise with new ideas and energy.

Cool Mom Picks: Have the Ultimate Baby Shower! | Gilt Little ...

It?s your last hurrah before your life changes forever, so this party better be good! We asked the moms behind CoolMomPicks.com (Kristen Chase and Liz Gumbinner) to share their tips on throwing the best baby bash ? here?s how to plan a sweet soiree in honor of a sleek mom-to-be.

Make it memorable:?We think throwing a memorable baby shower is like throwing any other fabulous party: Amazng food, delicious drinks (awesome mocktails?perhaps?), and your family and friends celebrating with you. While a lot of people stress about baby shower ?themes,? a theme really isn?t necessary unless you find a concept that reflects you; anyone can do a party around a child?s cartoon character, right? But if mermaids or Paris or even?vintage cameras?have a special connection to the mama-to-be, then it will have more meaning for both her and the guests.

Beyond the games:??A shower doesn?t need to have ?shower games? to be fun. To add special touches, think of activities or stations around the room that create meaningful keepsakes for the mom-to-be: Prop a table with a beautiful?journal or blank baby book?for each guest to share parenting advice, or ask them to write their thoughts on colored pieces of paper and drop them into a pretty basket.?Create a photo booth using your laptop, and add hilarious baby-themed props like pacifiers or giant baby bonnets. Or set up a video camera in one corner to allow guests to offer warm wishes for the soon-to-arrive baby ? or tell the funniest story they know about the parents. (Maybe the baby isn?t allowed to watch until his 18th birthday?)

Best invitations:?Invites go way beyond gingham style (ha!). We always love the array of options from?Paper Culture,?Minted, and?Tiny Prints, or you can find ready-made cards and fill them in yourself to save money. If you?re looking to do online invitations instead (increasingly socially acceptable!) our first stop is always?Paperless Post, whose cards look as amazing as paper cards and demand to be opened more than other online invitations do. The site can also help you track the guest list and you can have matching invitations printed (should the mama want a keepsake of one). Hint: She will.

Registry tips:?The truth is that you?ll often never know exactly what you need until the baby comes. Our tip is to pool a few different resources, from the charts in pregnancy books, to savvy bloggers (ahem), to your sister-in-law,?to ideas from the cool seasoned mom in your neighborhood. Registering online can save a ton of time, but you should consider hitting your local baby boutique to check out big-ticket gear in person; that car seat fabric may look way different when you?re in front of it, and maybe the stroller you?ve been coveting is harder to push than you imagined. Just remember, if you don?t get everything you want right away it?s okay. Newborn babies need very little at first ? not even a crib ? and these days, everyone delivers.

Top gifts:?While registries?help you get new parents just what they want, sometimes it?s nice to wrap a gift they wouldn?t buy for themselves. Beautiful layette essentials and coming-home outfits always guarantee oohs and ahhs at a shower, whether they?re from your favorite mall store or a small organic brand. The perfect muslin swaddler from Aden + Anais is a lifesaver, trust us. Keepsake rattles and baby books are always welcome gifts. A gorgeous Ergobaby carrier gets you so much more excited to strap it on ?? and psst, it?s a smart postpartum belly hider. And don?t forget to pamper mama too ? we remain grateful for those smart friends who brought us creams and body oils at our own showers. Thank you! Thank you!

*For more baby shower help, check out our annual?Ultimate Baby Shower Gift Guide, which has more than 150 of the coolest gift ideas for all kinds of babies and all kinds of families.

Structured reflection improves team performance

Apr. 8, 2013 ? Maybe the boss' staff meeting shouldn't be such a boring snooze, but rather a more structured event to improve the performance of the team, new basic research at The University of Alabama in Huntsville indicates.

With the word "team" ubiquitous to the point of clich? in the business world, the new research indicates that teams improve their performance when they meet in a structured environment in which each member reflects on his or her role and how it relates to the overall performance of the team.

Communication is essential in this reflexivity phase so that each team member develops greater situational awareness, which is the perception of their environment and what it may mean now and in the future, and better transactive memory, which is the ability to recall which team members have expertise in various roles.

The study of the reflexivity phase and communication by UAHuntsville graduate student Kristin Weger organized 40 virtual teams of four members each, connected to each other only by computer. "No team member knows who the other team members are," Weger said. "For this study, they could only communicate via a chat system."

The study was conducted through the UAHuntsville Psychology Department's Social Cognition and Teamwork Laboratory. "In our research in the lab, we try to identify when and under what conditions the best teamwork occurs," said Dr. Sandra Carpenter, a psychology professor and Weger's collaborator. "What we do is experimental work that typically uses college students to work on projects for a specific period of time, or we study college students as they do their own course projects. The results are applicable to the military, managers and team leaders of all types."

Weger's teams played a German-created video game designed for experimental and training purposes called NetOpFeuer 2.0, or Network Operations Fire, a computer simulated fire rescue. Weger, who is German, began her nine-month project by translating the game into English. The purpose of the game is for each team to save as much of a burning village and forest as possible, and team members are each assigned to a different role in the effort. The 20 reflexivity teams were all given the goal of improving their performance.

"Nobody has really done it before, looking at the reflexivity phase and its impact on communication," said Weger, whose resulting thesis will earn her a master's degree in experimental psychology with a specialization in industrial organizational psychology. Her work was awarded as the Psychology Department's outstanding thesis. She hopes to continue her studies as a doctoral candidate at the University of Bamberg in Germany.

Study teams were composed of volunteers and students. Each followed the same protocol. They trained on the video game to gain confidence in the task. Weger found that the 20 teams engaging in reflexive phases after the first game improved their subsequent performance by a statistically significant margin, in terms of the percentage of the village and forest they saved from being burned, compared to the 20 control teams who did not reflect on their performance.

In the first scenario, after playing the video game teams in the guided reflexivity condition next reflected for 10 minutes and discussed specific guiding questions on their strategy and how they'd change it for future rounds. Teams who received a guided reflexivity intervention had an initial performance of 59.88 percent of the village and forest saved from fire.

The second scenario was like the first, but the game layout was reversed so that it provided a new environment. "That enabled us to measure if their performance had improved," Weger said. After the guided reflexivity intervention, during the second scenario team performance increased to 68.38 percent saved.

"Giving them guidance in what to talk about influences their ability to communicate together and perform together," Weger said.

Control teams went through the same exercise but instead of the guided reflexivity phase, they discussed how to be more successful at their careers, an unrelated subject. "The control condition had an initial higher performance with 63.88 percent in scenario one," Weger said, "but did not increase their performance in scenario two, which was 63.80 percent."

The study found that communication among team members flourished during the discussion phase that happened after the first scenario, when teams that received a guided reflexivity intervention sent on average 21.15 chat messages about situation awareness events, whereas teams in the control condition sent on average 10.85 messages.

During the discussion phase, teams that received a guided reflexivity intervention sent on average 37.60 messages about reflexivity.

Donated by maker IABG, the video game calculated the performance of each team using an algorithm. Also under study was the degree to which each individual team member developed situational awareness and transactive memory.

"Each team member had a task, like one would operate the fire engine and one would run the helicopter," Weger said. "For teams in the guided reflexivity condition, knowledge and awareness of all aspects increased during the reflective discussion." Team members increased their awareness of their own roles, the knowledge base of their peers and how everything fit together to make a unit.

During the discussion phase, teams who received a guided reflexivity intervention sent on average 31.35 messages related to the transactive memory system, whereas teams in the control condition sent on average 15.50 messages.

Interestingly, Weger found in the control groups that there was a degree of voluntary reflexivity that also slightly increased their cohesiveness as a team. Teams in the control condition sent on average nine messages, indicating that teams do voluntarily reflect to a certain degree.

"Some research says that teams do not actually voluntarily reflect ," she said, "but I found that groups to some degree did reflect."

More research needs to be done, and Weger hopes to be the one doing it, but "if it goes along the same lines as we have done, then if you are previewing prior performance, developing new strategies and implementing new strategies, it can improve team performance."

The take-home point for your boss is the guidance aspect. "If you call them together to discuss their performance in a guided environment, it will improve," Weger said. "You have to put more training into communication."

"Other research has shown that if you intervene early and get the team to discuss what the task is and what their goals are, it improves their performance," said Dr. Carpenter.

But then there are always some slackers who mimic Wally from the comic strip Dilbert. One of Weger's teams decided during its reflexivity period not to save anything from the flames in thevideo game, so essentially it was doing no work. "I had to talk to them then and explain that they had a goal that had been set to improve their performance," she said.

So even though your boss might see an improvement in the team by employing reflexivity periods in a guided environment, and you might find staff meetings more engaging, it's still good to make sure everyone is indeed working toward the goal.

JetBlue Airways will get first U.S.-made Airbus jet

MOBILE, Alabama (Reuters) - JetBlue Airways Corp Chief Executive Dave Barger said on Tuesday that his airline will receive the first U.S.-assembled Airbus jet, which will roll off the assembly line in 2016.

Barger spoke at a groundbreaking for a $600 million factory of EADS' Airbus unit in Mobile, Alabama. The plant is expected to create 1,000 jobs, and bolster U.S. spending by Airbus, which already spends $13 billion with U.S. suppliers.

"We'll be the launch customer of this assembly line," Barger said. "We have well over 100 of the A320s today. It's a big day for JetBlue as well."

JetBlue is also expecting delivery of another 100 A320 narrow-body aircraft, he said.

No longer an upstart but not as big as Delta, United or the soon-to-be merged American Airlines-US Airways, JetBlue is one of the larger mid-sized U.S. carriers.

Although assembly is a relatively small part of the work of building a jet, Airbus is betting that having a U.S. facility will boost its credentials and help win deals. The Mobile plant will be only the second Airbus has outside Europe that builds its top-selling workhorse jet. The other is in China.

Israel closes Gaza crossing after rockets fired

(AP) ? Israel shut a crossing with Gaza after rockets were fired from the Hamas-ruled territory at the Jewish state on the day it commemorated the Holocaust.

The military said it closed the Kerem Shalom terminal Monday. Another crossing would be open for humanitarian cases only, it said.

Israel has blockaded the coastal territory since the Islamic militant Hamas took over in 2007.

Israeli police said several rockets were fired from Gaza at Israel the previous evening, as annual ceremonies were held nationwide to remember the 6 million Jews murdered by German Nazis and their collaborators.

Israeli TV showed footage of people in the south of the country abandoning a memorial ceremony and running for cover as sirens wailed warning of incoming rockets.

No injuries resulted from the attack, police said.

Virgin America best US airline performer in 2012

(AP) ? U.S. airlines scored their second best performance last year in the more than two decades that researchers have been measuring airline quality, with Virgin America the leader, says an annual report released Monday.

The report ranked the 14 largest U.S. airlines based on on-time arrivals, mishandled bags, consumer complaints and passengers who were bought tickets but were turned away because flights were over booked.

Airline performance in 2012 was the second highest in the 23 years that Wichita State University at Omaha in Nebraska and Purdue University in Indiana have tracked the performance of airlines. The airline's best year was 2011.

Virgin America, headquartered in Burlingame, Calif., did the best job on baggage handling and had the second-lowest rate of passengers denied seats due to overbookings. United Airlines, whose consumer complaint rate nearly doubled last year, had the worst performance. United has merged with Continental Airlines, but has had rough spots in integrating the operations of the two carriers.

The number of complaints consumers filed with the Department of Transportation overall surged by one-fifth last year to 11,445 complaints, up from 9,414 in 2011.

"Over the 20 some year history we've looked at it, this is still the best time of airline performance we've ever seen," said Dean Headley, a business professor at Wichita State University in Kansas, who has co-written the annual report. The best year was 2011, which was only slightly better than last year, he said.

Despite those improvements, it's not surprising that passengers are getting grumpier, Headley said. Carriers keep shrinking the size of seats in order to stuff more people into planes. Empty middle seats that might provide a little more room have vanished. And more people who have bought tickets are being turned away because flights are overbooked.

"The way airlines have taken 130-seat airplanes and expanded them to 150 seats to squeeze out more revenue, I think, is finally catching up with them," he said. "People are saying, 'Look, I don't fit here. Do something about this.' At some point airlines can't keep shrinking seats to put more people into the same tube," he said.

The industry is even looking at ways to make today's smaller-than-a-broom closet toilets more compact in the hope of squeezing a few more seats onto planes.

"I can't imagine the uproar that making toilets smaller might generate," Headley said, especially given that passengers increasingly weigh more than they use to. Nevertheless, "will it keep them from flying? I doubt it would."

The rate of complaints per 100,000 passengers also rose to 1.43 last year from 1.19 in 2011.

In recent years, some airlines have shifted to larger planes that can carry more people, but that hasn't been enough to make up for an overall reduction in flights.

The rate at which passengers with tickets were denied seats because planes were full rose to 0.97 denials per 10,000 passengers last year, compared with 0.78 in 2011.

It used to be in cases of overbookings that airlines usually could find a passenger who would volunteer to give up a seat in exchange for cash, a free ticket or some other compensation with the expectation of catching another flight later that day or the next morning. Not anymore.

"Since flights are so full, there are no seats on those next flights. So people say, 'No, not for $500, not for $1,000,' " said airline industry analyst Robert W. Mann Jr.

Regional carrier SkyWest had the highest involuntary denied-boardings rate last year, 2.32 per 10,000 passengers.

But not every airline overbooks flights in an effort to keep seats full. JetBlue and Virgin America were the industry leaders in avoiding denied boardings, with rates of 0.01 and 0.07, respectively.

United Airlines' consumer complaint rate was 4.24 complaints per 100,000 passengers. Southwest had the lowest rate, at 0.25. Southwest was among five airlines that lowered complaint rates last year compared to 2011. The others were American Eagle, Delta, JetBlue and US Airways.

Consumer complaints were significantly higher in the peak summer travel months of June, July and August when planes are especially crowded.

"As airplanes get fuller, complaints get higher because people just don't like to be sardines," Mann said.

The complaints are regarded as indicators of a larger problem because many passengers may not realize they can file complaints with the Transportation Department, which regulates airlines.

At the same time that complaints were increasing, airlines were doing a better job of getting passengers to their destinations on time.

The industry average for on-time arrival rates was 81.8 percent of flights, compared with 80 percent in 2011. Hawaiian Airlines had the best on-time performance record, 93.4 percent in 2012. ExpressJet and American Airlines had the worst records with only 76.9 percent of their planes arriving on time last year.

The industry's on-time performance has improved in recent years, partly due to airlines' decision to cut back on the number of flights.

"We've shown over the 20 years of doing this that whenever the system isn't taxed as much ? fewer flights, fewer people, less bags ? it performs better. It's when it reaches a critical mass that it starts to fracture," Headley said.

The industry's shift to charging for fees for extra bags, or sometimes charging fees for any bags, has significantly reduced the rate of lost or mishandled bags. Passengers are checking fewer bags than before, and carrying more bags onto planes when permitted.

The industry's mishandled bag rate peaked in 2007 at 7.01 mishandled bags per 1,000 passengers. It was 3.07 in 2012, down from 3.35 bags the previous year.

The report's ratings are based on statistics kept by the department for airlines that carry at least 1 percent of the passengers who flew domestically last year. The research is sponsored by Purdue University in Indiana and by Wichita State.

China kills market birds as flu found in pigeons

BEIJING (AP) ? China announced a sixth death from a new bird flu strain Friday, while authorities in Shanghai halted the sale of live fowl and slaughtered all poultry at a market where the virus was detected in pigeons being sold for meat.

The mass bird killing is the first so far as the Chinese government responds to the H7N9 strain of bird flu, which has sickened 16 people, many critically, along the eastern seaboard in its first known infections of people. The first cases were announced Sunday, while two more were reported Friday, both retirees who were seriously ill.

Health officials believe people are contracting the virus through direct contact with infected fowl and say there has been no evidence so far that the virus is spreading easily between people. However, scientists are watching closely to see if the flu poses a substantial risk to public health or could potentially spark a global pandemic.

The Agriculture Ministry confirmed late Thursday that the H7N9 virus had been detected in live pigeons on sale at a produce market in Shanghai. The killing of birds at the Huhuai market in Shanghai started Thursday night after the city's agricultural committee ordered it in a notice also posted on its website.

State media on Friday ran pictures of animal health officials in protective overalls and masks working through the night at the market, taking notes as they stood over piles of poultry carcasses in plastic bags. The area was guarded by police and cordoned off with plastic tape.

Experts urged Chinese health authorities to keep testing healthy birds, saying the H7N9 virus can infect birds without causing them to become ill, making it harder to detect than the H5N1 bird flu virus that is more familiar to Asian countries. H5N1 set off warnings when it began ravaging poultry across Asia in 2003 and has since killed 360 people worldwide, mostly after close contact with infected birds.

"In the past usually you would see chickens dying before any infections occurred in humans, but this time we've seen that many species of poultry actually have no apparent problems, so that makes it difficult because you lose this natural warning sign," said David Hui, an infectious diseases expert at the Chinese University of Hong Kong.

The city of Shanghai also announced a suspension of the sale of live poultry starting Saturday, city spokesman Xu Wei said at a news conference.

(AP Photo) CHINA OUT less? ?

Pigeon is a common type of poultry in Chinese cuisine and the birds are sold live in markets around the country. Chinese also raise pigeons as pets, but those tend to be a different type.

Hui said the pigeons were probably infected by wild or migratory birds, whose droppings can carry viruses. He said they were likely not the only species of poultry to be carrying the virus.

While health officials caution that there are no indications the virus can be transmitted from one person to another, scientists who have studied its genetic sequence said this week that the virus may have recently mutated into a form that spreads more easily to other animals, potentially posing a bigger threat to humans.

The latest death from the virus confirmed by the government Friday was a 64-year-old farmer in the eastern city of Huzhou. Authorities said Thursday the virus also killed a 48-year-old man who transported poultry for a living and a 52-year-old woman, both in Shanghai. Several among the infected are believed to have had direct contact with fowl.

Guidelines issued Wednesday by the national health agency identify butchers, breeders and sellers of poultry, and those in the meat processing industry as at higher risk.

Experts identified the first cases on Sunday. Some of the 16 confirmed cases fell ill several weeks ago but only now are being classified as having H7N9. The official Xinhua News Agency said six cases have been confirmed in Shanghai, six in Jiangsu, three in Zhejiang and one in Anhui.

Contacting Employers the Old Fashioned Way ? Career ...

Who would have ever thought that the use of telephones and the US Postal Service would become old fashioned to job seekers? On the flip side, who would think bringing back these old fashioned resources in finding employment could be considered creative? Today's younger job seeker is amazed at the idea of calling a potential employer over the phone much less sending a resume and cover letter through the mail. The very idea of printing a resume, printing a cover letter, signing the cover letter, addressing an envelope with a stamp, stuffing then sealing that enveloped and finally walking this envelope to the mail box is almost inconceivable in today's job market.

"Pounding the pavement" has become a lost art in seeking employment. Too many have flocked to the comfort of the online application process. As I have said many times, applying for a position online is a task. An effective job search is a process. As a job seeker, what are you willing to do in addition to applying online to secure your targeted job?

When looking for innovative or unique ways to be noticed by potential employers, why not first return to these two basic techniques used from the not so distant past:

Pick up the telephone: The internet provides easy access in finding general telephone numbers to every business in the world. Call employers. You can certainly call the HR department, but you will probably be more successful by calling the department in which you want to work. Emails can often time get lost, but phone calls are rarely lost or overlooked.

Mail your resume: Typing resumes and cover letters on bond paper and sending these job search packets through the mail used to be the most widely used practice for job seekers just 20 years ago. Today, very few job seekers take the time to print resume and cover letters to mail much less know what bond paper is in the first place. In addition, we are more likely to read the mail we physically receive over every email we receive. The volume of mail we receive at the office has dramatically decreased. Job seekers stand a very good chance of their letter being opened.

Applying online will get your resume into the company applicant tracking system. While some companies do look at these resumes for identifying talent, candidates must take extra steps to be noticed unless you believe in the needle in a haystack theory. In order to prove your interest and commitment for the job to employers, think about returning to basics if you will. Purchase a book of US postage stamps, stationery paper and envelopes, and good ink for your printer. The walk to the mailbox will be good for you. In addition, use the Internet to find a few phone numbers and dial the telephone. Dare to be innovative by returning to what many consider "old fashioned." You might be surprised with the positive feedback you receive.

A longer life for lithium-sulfur batteries

Apr. 2, 2013 ? Electric cars have still got it tough in the German marketplace. They are too expensive and their range is too short. This is an opportune time for a breakthrough in efficient and low-cost lithium-sulfur batteries.

There are currently over 40 million cars on Germany's roads. Only a fraction of them are powered by electric energy -- around 6,400 vehicles according to the Federal Ministry of Transport, Building and Urban Development. The comparatively short range of electric cars doesn't help their popularity, with drivers often having to start the search for a charging station after a mere 100 kilometers, not to mention the high price of the batteries, which cost several thousand euros. Remedying this situation has researchers looking at new options in developing more efficient technologies. An extremely promising avenue of research is the lithium-sulfur battery, which is significantly more powerful and less expensive than the better-known lithium-ion battery. Although their short lifespan has made them unsuitable for use in cars before now, this may be about to change in the foreseeable future.

Scientists at the Fraunhofer Institute for Material and Beam Technology IWS in Dresden have developed a new design that increases the charge cycles of lithium-sulfur batteries by a factor of seven. "During previous tests, the batteries scarcely crossed the 200-cycle mark. By means of a special combination of anode and cathode material, we have now managed to extend the lifespan of lithium-sulfur button cells to 1,400 cycles," says Dr. Holger Althues, head of the Chemical Surface Technology group at IWS, who is delighted with his team's breakthrough. The anode of the team's prototype is not made from the usual metallic lithium, but from a silicon-carbon compound instead. This compound is significantly more stable, as it changes less during each charging process than metallic lithium. The more the structure of the anode changes, the more it interacts with the liquid electrolyte, which is situated between the anode and the cathode and carries the lithium-ions. This process causes the liquid to break down into gas and solids and the battery to dry out. "In extreme cases, the anode "grows" to reach the cathode, creating a short circuit and causing the battery to stop working altogether," explains Althues.

The interplay between anode and cathode is the critical factor determining the performance and lifespan of a battery. In the lithium-sulfur model, the cathode is composed of elemental sulfur. The advantage here is that unlike cobalt -- the main cathode material used in lithium-ion batteries -- sulfur is available in almost unlimited quantities and is therefore cheaper. The problem remains, however, that sulfur also interacts with the liquid electrolyte, which impairs the performance of batteries and, in the worst case, causes them to lose capacity entirely. The IWS researchers are using porous carbons to slow down this process. "We have precisely altered the pores to allow the sulfur to lodge there, slowing down the rate at which it combines with the electrolyte," clarifies Althues. He and his colleagues have developed a method of manufacturing these special cathodes.

The experts at IWS measure the capacity of a battery in watt-hours per kilogram (Wh/kg). Over the long term, they expect lithium-sulfur batteries to reach an energy density of up to 600 Wh/kg. For comparison: the maximum energy density of the lithium-ion batteries currently in use is a mere 250 Wh/kg. "In the medium term, figures around the 500 Wh/kg mark are more realistic. In practical terms, this means you can drive twice as far with the same battery weight," says Althues. This of course implies that significantly lighter battery models are possible -- an interesting prospect not only for automakers but for smartphone manufacturers too. After all, the overall weight of smartphones would be greatly reduced if they had lighter batteries. "Lithium-sulfur technology might even make electric flying a realistic possibility. Although such progress is still a long way off," adds Althues.

The researchers are currently working on further optimizing the material and using it in larger battery models. They are also turning their attention to suitable manufacturing methods. And with good reason, as this is the only way the technology will reach a mass market, leading to a significant increase in the number of electric cars on Germany's roads.

Global warming mystery: Are North and South really polar opposites?

Two studies, one about plants covering previously frozen landscapes in the Arctic, the other about expanding winter sea ice in Antarctica, appear to say different things about global warming.

By Pete Spotts,?Staff writer / April 1, 2013

A Greenpeace activist dressed as a polar bear floats on the Moskva River to protest oil drilling in the Arctic, in Moscow, Russia, April 1, 2013.

Mikhail Metzel / AP

The amount of land in the high Arctic covered by trees and upright shrubs could increase by up to 52 percent by midcentury, warming the region to levels climate scientists had previously not expected to see there until 2100.

That's the take-home message from a new study that looks at statistical ties between climate and vegetation types to estimate how the Arctic's landscape could change with global warming. The impact of the vegetation changes on the region's climate not only would be felt at lower latitudes through changing atmospheric circulation patterns, researchers say. The changes also would affect the range and types of wildlife in the area and the livelihoods of the Inuit who rely on the wildlife for food.

The results are appearing just as a new study from the bottom of the world offers an explanation as to why warming in Antarctica might appear to some people to be on hold, given a 20-year trend of expansion in winter sea ice.

Taken together, the two studies highlight the ways in which human-triggered warming averaged over the entire planet can play out in unique ways in specific regions of the globe ? in this case, two regions that play a critical role in Earth's climate system as "sinks" for heat generated in tropics.

At the top of the world, warming at the surface has occurred at nearly twice the rate of warming as the world as a whole. Some studies indicate that the winter temperatures have been rising at least four times faster than the summer temperatures. This warming has brought trees and woody, upright shrubs to areas once dominated by tundra.

Previous studies of the impact of a greener Arctic on the region's climate indicated the trend would reinforce warming.

On the one hand, a green canopy could shade soils once the snow melts, keeping them cooler than they otherwise would be and slowing the release of CO2 from soils.?But a darker canopy also would capture and reradiate heat ? warming the air earlier in the spring and slowing the return of cold temperatures in the fall. In addition, during the growing season, trees give off water vapor, a potent greenhouse gas, through a process known as evapotranspiration. This also would tend to reinforce warming in the region.

Earlier studies had suggested that the factors that reinforce warming would win out, contributing 0.66 to 1.8 degrees Celsius (about 1.2 to 3 degrees Fahrenheit) to Arctic warming. But modelers had to make a best guess on how much additional land would be covered by trees and upright shrubs. They settled on an increase of about 20 percent by 2100.

A team led by Richard Pearson of the American Museum of Natural History in New York took a different approach. They used statistical tools to determine the climate conditions each of 10 broad vegetation types could tolerate. Then they used climate models to explore the range of conditions the models projected for the Arctic by 2050. The two sets of results allowed them to estimate the new ranges for the vegetation types. Some, such as trees and upright shrubs migrated north. Other types, in coastal regions with nowhere farther north to go, vanished.

The approach has been used for other regions, notes Scott Goetz, a senior scientist at the Woods Hole Research Institute in Woods Hole, Mass., and a member of the team performing the study. But, he adds, its the first time anyone has applied the technique to the Arctic.

Overall, the team found that if climate-induced shifts in plant types were patchy, the changes would affect 48 to 69 percent of the Arctic regions they studied above 60 degrees north latitude. Those regions spanned northern Russia, northern Alaska, and northern Canada.
