Researchers study signaling networks that set up genetic code
In a new study, researchers at the University of Illinois have identified and visualized the signaling pathways in protein-RNA complexes that help set the genetic code in all organisms. view more (2009-04-15)
Titanic survivors lived no longer than general population
In the closing song of the 1997 film Titanic, the heroine tells us that her heart "must go on and on" but a study in this week's Christmas issue of the BMJ shows that Titanic survivors lived no longer than the general population. view more (2003-12-17)
Chemical engineers discover new way to control particle motion potentially aiding micro- and nano-fluid systems for drug delivery, sensors, more
Chemical engineers at The University of Texas at Austin have discovered a new way to control the motion of fluid particles through tiny channels, potentially aiding the development of micro- and nano-scale technologies such as drug delivery devices, chemical and biological sensors, and components for miniaturized biological... view more...

Passports for penguins
Ground-breaking technology that will enable biologists to identify and monitor large numbers of endangered animals, from butterflies to whales, without being captured, will be shown to the public for the first time at this year's Royal Society Summer Science exhibition [30 June to 3 July]. view more (2008-06-30)
Diversity of trees in Ecuador's Amazon rainforest defies simple explanation
Trees in a hyper-diverse tropical rainforest interact with each other and their environment to create and maintain diversity, researchers report in the Oct. 24 issue of the journal Science. view more (2008-10-24)
Implications of the new HIV estimate for India
The 2007 UNAIDS/WHO AIDS epidemic update released last week has revised the global estimate of HIV/AIDS primarily due to a major reduction of the estimate for India to 2.5 million people living with HIV/AIDS, which is less than half of the previous official estimate of 5.7 million people. view more (2007-12-04)
Fusion in the fast lane
Using fast digital imaging, scientists from the Max Planck Institute of Colloids and Interfaces in Potsdam, Germany, together with researchers from Collîge de France, have succeeded in developing two different protocols by which one can initiate the fusion process in a controlled manner and observe the subsequent fusion dynamics with a... view more...

Researchers offer new theory for dogfish and skate population outburst on George's Bank
New research by scientists at the University of Maryland Center for Environmental Science Chesapeake Biological Laboratory questions the long-held belief that a lack of predators and competitors was the primary cause for the increase of skates and dogfish observed in Southern New England's George's Bank following overfishing of commercially... view more...

Tracking alien turbulences with Venus Express
New images and data from ESA's mission to Venus provide new insights into the turbulent and noxious atmosphere of Earth's sister planet. What causes violent winds and turbulences? Is the surface topography playing a role in the complex global dynamics of the atmosphere? Venus Express is on the case. view more (2007-04-04)
Interacting protein theory awaits test from new neutron analysis tools
An international collaboration directed by an Oak Ridge National Laboratory researcher has performed the first-ever atomic-detail computer simulation of how proteins vibrate in a crystal. view more (2007-09-28)
Sea otter study reveals striking variability in diets and feeding strategies
Ecologists have long observed that when food becomes scarce, animal populations exploit a wider range of food sources. view more (2008-01-15)
Studying rivers for clues to global carbon cycle
In the science world, in the media, and recently, in our daily lives, the debate continues over how carbon in the atmosphere is affecting global climate change. Studying just how carbon cycles throughout the Earth is an enormous challenge, but one Northwestern University professor is doing his part by studying one important segment -- rivers. view more (2008-02-11)
New population of Iberian lynx raises hope, says World Wildlife Fund
Spanish authorities have announced they have discovered a previously unknown population of Iberian lynx, triggering hope for one of the world's most endangered cat species, said World Wildlife Fund today. view more (2007-10-24)
Herpes viruses hedge their bets: latency boosts survival
Herpes viruses have two infectious phases: one just after infecting a new host, and one years or decades later when they reactivate. view more (2002-10-31)
Spotting evidence of directed percolation
A team of physicists has, for the first time, seen convincing experimental evidence for directed percolation, a phenomenon that turns up in computer models of the ways diseases spread through a population or how water soaks through loose soil. view more (2009-11-18)
Fluid Dynamics Works on Nanoscale in Real World
In 2000, Georgia Tech researchers showed that fluid dynamics theory could be modified to work on the nanoscale, albeit in a vacuum. Now, seven years later they've shown that it can be modified to work in the real world, too - that is, outside of a vacuum. The results appear in the February 9 issue of Physical Review Letters (PRL). view more (2007-02-26)
Fly population set to double with global warming
A leading biological scientist from the University of Southampton is warning of massive increases in the UK's fly population if temperatures continue to rise. view more (2004-09-27)
Video game Everquest 2 provides new way to study human behavior, says U of Minnesota researcher
Can researchers study the populations of online video games, like Everquest 2, just as they study traditional communities like Miami, Pittsburgh or Minneapolis? view more (2009-03-02)
Slip rate along the Lijiang-Ninglang fault zone estimated from repeating microearthquakes
The China Digital Seismic Network (CDSN) provides excellent opportunities to quantify the kinematics and characterize the dynamics of the active fault systems in China. view more (2008-12-22)
Pursuing the future of personal genomics
Giving Nobel Laureate James Watson his personal genome was just the beginning. In a future that promises similar information to much of the population, ethicists, scientists and physicians are only beginning to understand and consider the possibilities. view more (2007-09-21)
