Snail venoms reflect reduced competition
A study of venomous snails on remote Pacific islands reveals genetic underpinnings of an ecological phenomenon that has fascinated scientists since Darwin. view more (2009-05-21)
100 reasons to change the way we think about genetics
For years, genes have been considered the one and only way biological traits could be passed down through generations of organisms. view more (2009-05-19)
The evolutionary foundation of genomic imprinting in lower vertebrates
A Chinese scientist group working in College of Life Science, Zhejiang University, has shown that, as mammalian Igf2 CpG island, goldfish Igf2 CpG island has a parental differentially methylated region (DMR). view more (2009-05-18)
New dinosaur species possible in Northwestern Alberta
The discovery of a gruesome feeding frenzy that played out 73 million years ago in northwestern Alberta may also lead to the discovery of new dinosaur species in northwestern Alberta. view more (2009-05-13)
CCNY, CSHL biologists find birdsong of isolates reverts to norm over several generations
In an experiment that points to a role for genetics in the development of culture, biologists at The City College of New York (CCNY) and Cold Spring Harbor Laboratory (CSHL) have discovered that zebra finches raised in isolation will, over several generations, produce a song similar to that sung by the species in the wild. view more (2009-05-04)
Darwin in a test tube
As described in an article published this week in an advance, online edition of the journal Proceedings of the National Academy of Sciences (PNAS), the work demonstrates some of the classic principles of evolution. view more (2009-04-30)
Remembrance of things past influences how female field crickets select mates
UC Riverside biologists researching the behavior of field crickets have found for the first time that female crickets remember attractive males based on the latter's song, and use this information when choosing mates. view more (2009-04-22)
Museum specimens aid conservation effort in Madagascar
There is a new tool for those developing conservation strategies for threatened species and landscapes: museum specimens. Richard Pearson and Christopher Raxworthy of the American Museum of Natural History dusted off a number of collections from Madagascar and used the location information associated with each species to test different ideas... view more...

Tentacles of venom: new study reveals all octopuses are venomous
Once thought to be only the realm of the blue-ringed octopus, researchers have now shown that all octopuses and cuttlefish, and some squid are venomous. The work indicates that they all share a common, ancient venomous ancestor and highlights new avenues for drug discovery. view more (2009-04-15)
IU astronomer's discovery poses challenge to galaxy formation theories
A team led by an Indiana University astronomer has found a sample of massive galaxies with properties that suggest they may have formed relatively recently. view more (2009-04-13)
Scorpion biodiversity
Scorpions possess resistance to high temperatures and the ability to conserve water for long periods of time, and as a result thrive in hot and arid parts of the world. view more (2009-04-10)
A new link between nickel, methane gas and the evolution of complex life forms on Earth
A University of Alberta researcher is lead author on a paper that reaches back billions of years to establish a new link between nickel, methane gas and the evolution of complex life forms on Earth. view more (2009-04-09)
Hundreds of natural-selection studies could be wrong, study demonstrates
Scientists at Penn State and the National Institute of Genetics in Japan have demonstrated that several statistical methods commonly used by biologists to detect natural selection at the molecular level tend to produce incorrect results. view more (2009-03-31)
AAAS, leading Texas scientists urge state board to reject anti-evolution effort
Leading members of the Texas scientific community, in collaboration with the American Association for the Advancement of Science (AAAS), have urged the Texas State Board of Education to reject amendments to the state's draft science standards that would undermine sound science teaching. view more (2009-03-25)
Optimum running speed is stride toward understanding human body form
Runners, listen up: If your body is telling you that your pace feels a little too fast or a little too slow, it may be right. view more (2009-03-20)
Elephant shark genome sequence leads to discovery of color perception in deep-sea fish
The elephant shark, a primitive deep-sea fish that belongs to the oldest living family of jawed vertebrates, can see color much like humans can. view more (2009-03-18)
Catching the common cold virus: BYU researchers coming down with the rhinovirus genome
A new study by Brigham Young University researchers on the virus behind nearly half of all cold infections explains how and where evolution occurs in the rhinovirus genome and what this means for possible vaccines. view more (2009-03-17)
How Increased UV Exposure Impacts Plants
As the first plant life to emerge from the water and develop on dry earth, bryophytes offer a unique opportunity for researchers to understand the development of protections against ultraviolet radiation. view more (2009-03-10)
Ocean's journey towards the center of the Earth
A Monash geoscientist and a team of international researchers have discovered the existence of an ocean floor was destroyed 50 to 20 million years ago, proving that New Caledonia and New Zealand are geographically connected. view more (2009-03-05)
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)
