Scientists alter sexual orientation in worms
University of Utah biologists genetically manipulated nematode worms so the animals were attracted to worms of the same sex - part of a study that shows sexual orientation is wired in the creatures' brains.
Scientists melt million-year-old ice in search of ancient microbes
Researchers from the University of Delaware and the University of California at Riverside have thawed ice estimated to be at least a million years old from above Lake Vostok, an ancient lake that lies hidden more than two miles beneath the frozen surface of Antarctica.
Gene study supports single main migration across bering strait
Did a relatively small number of people from Siberia who trekked across a Bering Strait land bridge some 12,000 years ago give rise to the native peoples of North and South America?
New drought-tolerant plants offer hope for warming world
Genetically engineered crop plants that survive droughts and can grow with 70 percent less irrigation water have been developed by an international team led by researchers at the University of California, Davis. The discovery offers hope for global agriculture that is already grappling with limited and variable water supplies.
New BTI study unravels how plants respond to light
Researchers at the Boyce Thompson Institute for Plant Research (BTI) on Cornell's campus report a breakthrough in understanding how plants perceive and respond to light.
Fin whales' big gulp
Some baleen whales, in their powerful feeding lunges, gulp a volume of water equal to a school bus, according to new calculations by biologists at the University of British Columbia and the University of California, Berkeley.
Group selection, a theory whose time has come ... Again
In landmark article, David Sloan Wilson and Edward O. Wilson lead sociobiology out of the theoretical wilderness.
Hellish' hot springs yield greenhouse gas-eating bug
A new species of bacteria discovered living in one of the most extreme environments on Earth could yield a tool in the fight against global warming.
Most ancient case of tuberculosis found in 500,000-year-old human
Although most scientists believe tuberculosis emerged only several thousand years ago, new research from The University of Texas at Austin reveals the most ancient evidence of the disease has been found in a 500,000-year-old human fossil from Turkey.
Researchers brewing energy from sweet potatoes
Sweet potatoes, a staple on holiday dinner tables, are being re-engineered by North Carolina State University scientists as source of ethanol to help the U.S. reduce its dependence on imported oil – and ease the biofuel industry's troublesome reliance on corn.

New hypothesis for origin of life proposed
Life may have begun in the protected spaces inside of layers of the mineral mica, in ancient oceans, according to a new hypothesis.
Herbal extract found to increase lifespan
The herbal extract of a yellow-flowered mountain plant indigenous to the Arctic regions of Europe and Asia increased the lifespan of fruit fly populations, according to a University of California, Irvine study.
Walking tall to protect the species
The transition from apes to humans may have been partially triggered by the need to stand on two legs, in order to safely carry heavier babies. This theory of species evolution presented by Lia Amaral from the University of São Paulo in Brazil has just been published online in Springer's journal, Naturwissenschaften.
Doe jgi community sequencing program delivers first moss genome
Messages from nearly a half-billion years ago, conveyed via the inventory of genes sequenced from a present-day moss, provide clues about the earliest colonization of dry land by plants.
Are humans evolving faster?
Researchers discovered genetic evidence that human evolution is speeding up - and has not halted or proceeded at a constant rate, as had been thought - indicating that humans on different continents are becoming increasingly different.
Heads or tails? Scientists id gene key to regenerating flatworms
When cut, a planarian flatworm can regenerate a new head, new tail or even entire new organisms from a tiny fragment of its body--a phenomenon that has puzzled researchers for more than 100 years.
Building disease-beating wheat
Disease resistance genes from three different grass species have been combined in the world's first 'trigenomic' chromosome, which can now be used to breed disease resistant wheat varieties.
Genetic switch for circadian rhythms discovered
University of California, Irvine researchers have identified the chemical switch that triggers the genetic mechanism regulating our internal body clock.
More evidence for new species hidden in plain sight
Two articles published in the online open access journals BMC Evolutionary Biology and BMC Biology provide further evidence that we have hugely underestimated the number of species with which we share our planet.
Losses of long-established genes contributed to human evolution
Bioinformatics postdoctoral researcher Jingchun Zhu and graduate student Zack Sanborn collaborated with other UCSC researchers to identify genes lost during human evolution.
