Dinosaur extinction didn't cause the rise of present-day mammals, claim researchers
A new, complete 'tree of life' tracing the history of all 4,500 mammals on Earth shows that they did not diversify as a result of the death of the dinosaurs, says new research published in Nature today.   view more (2007-03-29)

Ocean growing more acidic faster than once thought
University of Chicago scientists have documented that the ocean is growing more acidic faster than previously thought. In addition, they have found that the increasing acidity correlates with increasing levels of atmospheric carbon dioxide.   view more (2008-11-25)

Panamanian termite goes ballistic: Fastest mandible strike in the world
A single hit on the head by the termite Termes panamensis (Snyder), which possesses the fastest mandible strike ever recorded, is sufficient to kill a would-be nest invader, report Marc Seid and Jeremy Niven, post-doctoral fellows at the Smithsonian Tropical Research Institute and Rudolf Scheffrahn... view more (2008-11-25)

Significant new method developed for characterizing density wave features
In a paper published in The Astronomical Journal (133:2584-2606, June 2007) Dr. Xiaolei Zhang, of the Naval Research Laboratory, and Dr. Ronald J. Buta, of the University of Alabama, report that they have developed an accurate and widely-applicable method for characterizing density wave features in... view more (2007-07-10)

Getting an evolutionary handle on life after reproduction
Since many animals live beyond their fertile years, biologists have searched for evolutionary clues to this extended lifespan.   view more (2005-12-27)

Evolution in action? African fish could be providing rare example of forming two separate species, Cornell scientists speculate
Avoiding quicksand along the banks of the Ivindo River in Gabon, Cornell neurobiologists armed with oscilloscopes search for shapes and patterns of electricity created by fish in the water.   view more (2006-06-02)

LSU scientists develop new theory about human genome evolution
A group of LSU researchers, led by biological sciences Professor Mark Batzer, have unraveled the details of a 25-million-year-old evolutionary process in the human genome. Their study focused on the origin and spread of transposable elements in the genome, many of which are known to be related to... view more (2005-07-01)

New moth variety disarms plants guarded by selenium
In new work, researchers report that the ability of plants to defend themselves by accumulating high levels of a toxic element can be overcome by some insects, and that such adaptation potentially echoes in the food web as other predators and parasites may in turn evolve to deal with high levels of... view more (2006-11-21)

Sea snails break the law
Lizards gave rise to legless snakes. Cave fishes don't have eyeballs. In evolution, complicated structures often get lost. Dollo's Law states that complicated structures can't be re-evolved because the genes that code for them were lost or have mutated.   view more (2007-04-25)

Meat-eating dinosaur from Argentina had bird-like breathing system
The remains of a 30-foot-long predatory dinosaur discovered along the banks of Argentina's Rio Colorado is helping to unravel how birds evolved their unusual breathing system.   view more (2008-09-30)

The turbidity of wine has an influence on the aroma of the ferment, but not on the accumulation of biogenic amines
The turbidity of red wine during its ageing in oak casks has an influence on the accumulation of volatile compounds and, thereby, on the wine's aroma, but not on the accumulation of biogenic amines.   view more (2006-11-28)

How new diseases from insects hit people like the plague
Scientists have traced the first steps in the way some new diseases emerge, and how harmless bacteria living in insects become dangerous disease-causing bugs which can affect humans, like the plague or anthrax. Researchers from the University of Bath are presenting their results today (Wednesday,... view more (2004-08-23)

A new control mechanism for genetic code translation discovered in bacteria
Almost all organisms, from bacteria to human beings, share the same genetic code, a group of universal instructions used to convert DNA or RNA sequences into proteins, the "building blocks" of life.   view more (2008-02-15)

Old developmental pathways spawn revolutionary evolutionary changes
When the larvae of the primitive social insect Polistes metricus, a paper wasp, slips into the quiet pupal stage, she doesn't know if she'll arise a worker or gyne (future queen) - unless she consults with Arizona State University's social insect researcher Gro Amdam.   view more (2007-09-07)

Good news: How the Earth will survive when the Sun becomes a supergiant
The astronomy textbooks will have to be rewritten, say astrophysicists at the University of Sussex who have re-examined standard calculations about solar evolution and the distant future of the Earth. The textbooks tell us that one day the Sun will burn up its nuclear fuel and expand to an enormous... view more (2002-01-08)

Tufts researchers shine light on firefly mysteries
This summer, in a darkened meadow west of Boston, Tufts University biologists are continuing to shine new light on the frenzied love life of fireflies.   view more (2005-06-20)

New deep space images of distant strip of sky to be available on Google
A global project to map a distant strip of the universe is releasing its data today to scientists and the public to be used as part of Google Sky, a new feature of Google Earth.   view more (2007-10-04)

DNA chunks, chimps and humans
Researchers have carried out the largest study of differences between human and chimpanzee genomes, identifying regions that have been duplicated or lost during evolution of the two lineages.   view more (2008-11-06)

Insects evolved radically different strategy to smell
Darwin's tree of life represents the path and estimates the time evolution took to get to the current diversity of life. Now, new findings suggest that this tree, an icon of evolution, may need to be redrawn.   view more (2008-04-14)

Woolly mammoth genome comes to life
A McMaster University geneticist, in collaboration with genome researchers from Penn State University and the American Museum of Natural History has made history by mapping a portion of the woolly mammoth's genome.   view more (2005-12-23)

Study: Delaying evolution of drug resistance in malaria parasite possible
There's no magic bullet for wiping out malaria, but a new study offers strong support for a method that effectively delays the evolution of drug resistance in malaria parasites, a University of Florida researcher says.   view more (2008-09-05)

heic0812: The Antennae Galaxies move closer
New research on the Antennae Galaxies using the Advanced Camera for Surveys onboard the NASA/ESA Hubble Space Telescope shows that this benchmark pair of interacting galaxies is in fact much closer than previously thought - 45 million light-years instead of 65 million light-years   view more (2008-05-12)

The delayed rise of present-day mammals
It took 10 to 15 million years after the dinosaurs were wiped out before modern mammals-including our ancient human ancestors-were able to diversify and rise to their present-day prominence across the globe, a landmark new study has found.   view more (2007-03-29)

Computational biochemist uncovers a molecular clue to evolution
A Florida State University researcher who uses high-powered computers to map the workings of proteins has uncovered a mechanism that gives scientists a better understanding of how evolution occurs at the molecular level.   view more (2008-09-11)

LSUHSC research finds evidence of RNA in structures essential to cell division
Research led by Mark Alliegro, PhD, Professor of Cell Biology and Anatomy at Louisiana State University Health Sciences Center at New Orleans, provides evidence for the first time that centrosomes, which play a key role in cell division, may carry their own genetic machinery, answering a... view more (2006-06-14)
