Research output in developing countries reveals 194 percent increase in five years
The partners of Research4Life announced today at the World Conference of Science Journalists 2009 that a new research impact analysis has demonstrated a dramatic rise in research output by scientists in the developing world since 2002. By comparing absolute growth in published research before (1996 � 2002) and after (2002 - 2008) the advent of the Research4Life programs, the analysis has revealed a 194 percent or 6.4-fold increase in articles published in peer reviewed journals.

ASU scientist: Study of first wave of swine flu requires revised public health strategies
Gerardo Chowell-Puente, a mathematical epidemiologist at Arizona State University, is co-author of a new study of the A(H1N1) influenza pandemic strain circulating around the world. The study's findings reveal an age shift in the proportion of cases toward a younger population when compared with historical patterns of seasonal influenza in Mexico. The findings are published June 29 online in the New England Journal of Medicine.

Study on keeping nuclear bombs from US ports shows misplaced fear over cargo scanning cost
A two-tiered scanning-protocol for inspecting all containers at international ports could be the most affordable approach to ensuring containers moving through the global transportation system are not carrying nuclear bombs, according to a paper being presented at a services special interest group meeting of the Institute for Operations Research and the Management Sciences.

CSHL scientists harness logic of 'Sudoku' math puzzle to vastly enhance genome-sequencing capability
Combining a 2,000-year-old Chinese math theorem with concepts from cryptology, scientists from Cold Spring Harbor Laboratory have devised "DNA Sudoku" -- a pooling strategy that allows tens of thousands of DNA samples to be combined and sequenced all at once. The new strategy promises to reduce costs dramatically, with sequencing projects that cost $10 million in the past now estimated to cost less than $80,000.

Mate selection: How does she know he'll take care of the kids?
Throughout the animal kingdom brilliant colors or elaborate behavioral displays serve as "advertisements" for attracting mates. But, what do the ads promise, and is there truth in advertising? Researchers at Yale theorize that when males must provide care for the survival of their offspring, the males' signals will consistently be honest -- and they may devote more of their energy to caring for their offspring than to being attractive.

Rare disorder gives modelers first glimpse at immune system development
Children born without thymus glands have given Duke University Medical Center researchers a rare opportunity to watch as a new immune system develops its population of infection-fighting T cells. Researchers led by Thomas Kepler, Ph.D., division chief of computational biology, tracked three young patients after thymus tissue transplantation to measure the growth of a T cell population -- with all of its diversity -- and learn about regulation mechanisms.
