Why are there so many more species of insects? Because insects have been here longer
J. B. S. Haldane once famously quipped that "God is inordinately fond of beetles." Results of a study by Mark A. McPeek of Dartmouth College and Jonathan M. Brown of Grinnell College suggest that this fondness was expressed not by making so many, but rather by allowing them to persist for... view more (2007-04-04)

Attack of the invasive garden ants
An ant that is native to Eurasia is threatening to become the latest in a procession of species to invade Europe, as a result of inadvertent human introduction. Research published in the online open access journal BMC Biology demonstrates that the invasive garden ant, Lasius neglectus, which is a... view more (2008-02-26)

The Evolution of Aversion: Why even children are fearful of snakes
Some of the oldest tales and wisest mythology allude to the snake as a mischievous seducer, dangerous foe or powerful iconoclast; however, the legend surrounding this proverbial predator may not be based solely on fantasy. As scientists from the University of Virginia recently discovered, the... view more (2008-02-28)

Sussex psychologists study what causes children's fears and phobias
Dr Andy Field, lecturer in psychology and research fellow Robin Banerjee at the University of Sussex have just won a three-year grant from the Economic and Social Research Council (ESRC) to investigate how fears and phobias are formed. "A phobia is a clinically diagnosed level of fear about a... view more (2002-01-21)

Flies in a spider's web: Galaxy caught in the making
In nature spiders earn our respect by constructing fascinating, well-organised webs in all shapes and sizes. But the beauty masks a cruel, fatal trap. Analogously, the NASA/ESA Hubble Space Telescope has found a large galaxy 10.6 billion light-years away from Earth (at a redshift of 2.2) that is... view more (2006-10-12)

Wales hosts world workshop for better conservation
These special scientists, known as taxonomists are members of BioNET International, the brainchild of Professor Tecwyn Jones of Cardiff University. They are skilled in the science concerned with identifying, classifying and understanding the relationships of the myriad species of organisms which... view more (1999-08-16)

Evolution of animal personalities
Animals differ strikingly in character and temperament. Yet only recently has it become evident that personalities are a widespread phenomenon in the animal kingdom.   view more (2007-05-31)

Study shows Google favored over other search engines by webmasters
Web site policy makers who use robots.txt files as gatekeepers to specify what is open and what is off limits to Web crawlers have a bias that favors Google over other search engines, say Penn State researchers whose study of more than 7,500 Web sites revealed Google's advantage.   view more (2007-11-16)

Spider silks, the ecological materials of tomorrow?
Spider silks could become the intelligent materials of the future, according to a review article published this month in the journal Microbial Cell Factories. The characteristics of spider silk could have applications in areas ranging from medicine to ballistics.   view more (2004-11-30)

Steep oxygen decline halted first land colonization by Earth's sea creatures
Vertebrate creatures first began moving from the world's oceans to land about 415 million years ago, then all but disappeared by 360 million years ago.   view more (2006-10-24)

Brown-led study rearranges some branches on animal tree of life
A study led by Brown University biologist Casey Dunn uses new genomics tools to answer old questions about animal evolution. The study is the most comprehensive animal phylogenomic research project to date, involving 40 million base pairs of new DNA data taken from 29 animal species.   view more (2008-03-06)

Study finds two supermassive black holes spiraling toward collision
A pair of supermassive black holes in the distant universe are intertwined and spiraling toward a merger that will create a single super-supermassive black hole capable of swallowing billions of stars.   view more (2006-04-06)

When cave crickets go out for dinner, they really go, researchers say
Cave crickets travel farther from their homes to forage - by about double - than their previously reported range, researchers have discovered.   view more (2005-09-08)

Agent in red wine found to keep hearts young
How, scientists wonder, do the French get away with a clean bill of heart health despite a diet loaded with saturated fats?   view more (2008-06-04)

Scientists find how amber becomes death trap for watery creatures
Shiny amber jewelry and a mucky Florida swamp have given scientists a window into an ancient ecosystem that could be anywhere from 15 million to 130 million years old.   view more (2007-10-19)

MIT creates 3-D scaffold for growing stem cells
Stem cells grew, multiplied and differentiated into brain cells on a new three-dimensional scaffold of tiny protein fragments designed to be more like a living body than any other cell culture system.   view more (2006-12-27)

Beetles could prove a hit with the aircraft industry
A species of beetle, that squirts its predators with a high-pressure spray of boiling liquid, could provide the key to significant improvements in aircraft engine design. The bombardier beetle's unique natural combustion technique is being studied to see if it can be copied for use in the aircraft... view more (2003-12-08)

Fossils older than dinosaurs reveal pattern of early animal evolution on Earth
The abundant diversity of characteristics within species likely helped fuel the proliferation and evolution of an odd-looking creature that emerged from an unprecedented explosion of life on Earth more than 500 million years ago.   view more (2007-07-27)

Substance in red wine found to keep hearts young
How do the French get away with a clean bill of heart health despite a diet loaded with saturated fats? Scientists have long suspected that the answer to the so-called "French paradox" lies in red wine. Now, the results of a new study bring them closer to understanding why.   view more (2008-06-05)

Peptide discovered in scorpion venom may hold key to secretory diseases
Researchers have discovered a peptide in scorpion venom that may hold the key to understanding and controlling cystic fibrosis and other secretory diseases.   view more (2008-02-15)
