Female spiders are voracious predators and consume a wide range of prey, which sometimes includes their mates.   view more (2008-09-11)

Glasgow ecologist wins British Ecological Society award
Glasgow University ecologist Dr Hanna Kokko will be awarded the British Ecological Society~s Founders~ Prize at the BES Winter Meeting which will be held at the University of Birmingham on 3-5 January 2001. The prize is awarded every two years to an outstanding ecologist early in their career for... view more (2000-12-15)

Beyond a 'speed limit' on mutations, species risk extinction
Harvard University scientists have identified a virtual "speed limit" on the rate of molecular evolution in organisms, and the magic number appears to be 6 mutations per genome per generation -- a level beyond which species run the strong risk of extinction as their genomes lose stability.   view more (2007-10-02)

Primordial fish had rudimentary fingers
Tetrapods, the first four-legged land animals, are regarded as the first organisms that had fingers and toes. Now researchers at Uppsala University can show that this is wrong. Using medical x-rays, they found rudiments of fingers in the fins in fossil Panderichthys, the "transitional... view more (2008-09-22)

Key brain regulatory gene shows evolution in humans
Researchers have discovered the first brain regulatory gene that shows clear evidence of evolution from lower primates to humans.   view more (2005-12-13)

Coelacanth fossil sheds light on fin-to-limb evolution
A 400 million-year-old fossil of a coelacanth fin, the first finding of its kind, fills a shrinking evolutionary gap between fins and limbs.   view more (2007-08-01)

Genome archaeology illuminates the genetic engineering debate
Genome Research's cover story for Oct. 2 tells a tale of "genome archaeology" by genetic researchers who dug deeply into the long history of maize and rice.   view more (2006-10-04)

Human-chimp difference may be bigger
Approximately 6 percent of human and chimp genes are unique to those species, report scientists from Indiana University Bloomington and three other institutions.   view more (2006-12-20)

Blame Our Evolutionary Risk of Cancer on Our Body Mass
A key enzyme that cuts short our cellular lifespan in an effort to thwart cancer has now been linked to body mass.   view more (2006-12-06)

Fungi can tell us about the origin of sex chromosomes
Fungi do not have sexes, just so-called mating types. A new study being published today in the prestigious journal PLoS shows that there are great similarities between the parts of DNA that determine the sex of plants and animals and the parts of DNA that determine mating types in certain fungi.   view more (2008-03-18)

Sticks and Stones: A New Study on Social and Physical Pain
We all know the famous saying: "Sticks and stones may break my bones, but words will never hurt me," but is this proverb actually true?   view more (2008-08-28)

Low oxygen and molybdenum in ancient oceans delayed evolution of life by 2 billion years
A deficiency of oxygen and the heavy metal molybdenum in the ancient deep ocean may have delayed the evolution of animal life on Earth by nearly two billion years, a study led by UC Riverside biogeochemists has found.   view more (2008-03-27)

Bacteria from sponges make new pharmaceuticals
Thousands of interesting new compounds have been discovered inside the bodies of marine sponges.   view more (2007-09-04)

Earliest known fossil fish discovered in China
Professor Simon Conway Morris, of the Department of Earth Sciences, University of Cambridge, and Professor Degan Shu, of Northwest University, in Xi'an, China, have been analysing the fossils, along with eight other scientists from China.   view more (1999-11-02)

Natural selection has strongly influenced recent human evolution, Cornell/Celera Genomics study finds
he most detailed analysis to date of how humans differ from one another at the DNA level shows strong evidence that natural selection has shaped the recent evolution of our species.   view more (2005-10-24)

Fossil discovery marks earliest record of limbloss in ancient lizard
A University of Alberta paleontologist has helped discover the existence of a 95 million-year-old snakelike marine animal, a finding that provides not only the earliest example of limbloss in lizards but the first example of limbloss in an aquatic lizard.   view more (2007-03-23)

Uncertain rainy days make birds turn to family, Cornell study finds
Rather than striking out to raise their family, members of some bird species cooperate to help raise their siblings, nephews, nieces, cousins -- or even unrelated young. Researchers have long noted which factors lead to these seemingly altruistic decisions, but now for the first time, Cornell... view more (2007-08-17)

Swedish-Chinese research team uncovers the history of the nose
Our ancestors had two nostrils, one front and one back, but no opening on the palate or in the throat. They could smell, but not breathe with their nose. How did our nose evolve? Per Ahlberg, Uppsala university, and Zhu Min, department of Vertebrate Paleontology in Beijing, China, has now found a... view more (2004-11-03)

Neuron Cell Stickiness May Hold Key to Evolution of the Human Brain
The stickiness of human neurons may have been a key factor in why the human brain evolved beyond the brains of our primate relatives. In a study comparing the genomes of humans, chimpanzees, mice and other vertebrates, researchers at the U.S. Department of Energy's Lawrence Berkeley National... view more (2006-11-06)

Yerkes researchers identify language feature unique to human brain
Researchers at the Yerkes National Primate Research Center, Emory University, have identified a language feature unique to the human brain that is shedding light on how human language evolved. The study marks the first use of diffusion tensor imaging (DTI), a non-invasive imaging technique, to... view more (2008-03-24)

Spitzer nets thousands of galaxies in a giant cluster
In just a short amount of time, NASA's Spitzer Space Telescope has bagged more than a thousand previously unknown dwarf galaxies in a giant cluster of galaxies.   view more (2007-05-29)

K-State researchers study gene regulation in insects
Susan Brown, an associate professor of biology at Kansas State University, is interested in how evolution generates so much diversity in insects shapes and forms.   view more (2006-04-28)

A gene divided reveals the details of natural selection
In a molecular tour de force, researchers at the University of Wisconsin-Madison have provided an exquisitely detailed picture of natural selection as it occurs at the genetic level.   view more (2007-10-11)

Space And Security Policy In Europe
A study on "Space and Security Policy in Europe" was initiated by ESA in the framework of its General Studies Programme. It has been performed by a network of European experts in space and security under the coordination of IAI (Istituto Affari Internazionali, Italy). The research team... view more (2003-12-11)

Migrating squid drove evolution of sonar in whales and dolphins, researchers argue
Behind the sailor's lore of fearsome battles between sperm whale and giant squid lies a deep question of evolution: How did these leviathans develop the underwater sonar needed to chase and catch squid in the inky depths"   view more (2007-09-06)
