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)

Researchers Shed Light on Evolution of Gene Regulation
Scientists at Penn State have shed light on some of the processes that regulate genes -- such as the processes that ensure that proteins are produced at the correct time, place, and amount in an organism -- and they also have shed light on the evolution of the DNA regions that regulate genes.   view more (2008-11-25)

Two From One-Pitt Research Maps Out Evolution of Genders From Hermaphroditic Ancestors
Research from the University of Pittsburgh published in the Nov. 20 edition of "Heredity" could finally provide evidence of the first stages of the evolution of separate sexes, a theory that holds that males and females developed from hermaphroditic ancestors.   view more (2008-11-21)

Worker ants of the world, unite! You have nothing to lose but your fertility
The highly specialized worker castes in ants represent the pinnacle of social organization in the insect world. As in any society, however, ant colonies are filled with internal strife and conflict. So what binds them together? More than 150 years ago, Charles Darwin had an idea and now he's been... view more (2008-11-20)

Stopping germs from ganging up on humans
Keeping germs from cooperating can delay the evolution of drug resistance more effectively than killing germs one by one with traditional drugs such as antibiotics, according to new research from The University of Arizona in Tucson.   view more (2008-11-20)

Forced evolution: Can we mutate viruses to death?
It sounds like a science fiction movie: A killer contagion threatens the Earth, but scientists save the day with a designer drug that forces the virus to mutate itself out of existence. The killer disease? Still a fiction. The drug? It could become a reality thanks to a new study by Rice University... view more (2008-11-11)

Sedimentary records link Himalayan erosion rates and monsoon intensity through time
Throughout history, the changing fortunes of human societies in Asia have been linked to variations in the precipitation resulting from seasonal monsoons.   view more (2008-11-10)

Annuals converted into perennials
Annual crops grow, blossom and die within one year. Perennials overwinter and grow again the following year. The life strategy of many annuals consists of rapid growth following germination and rapid transition to flower and seed formation, thus preventing the loss of energy needed to create... view more (2008-11-10)

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)

'Junk' DNA proves functional
In a paper published in Genome Research on Nov. 4, scientists at the Genome Institute of Singapore (GIS) report that what was previously believed to be "junk" DNA is one of the important ingredients distinguishing humans from other species.   view more (2008-11-05)

Throwing light on the dark side of the Universe
Although we may believe humans know a lot about the Universe, there are still a lot of phenomena to be explained. A team of cosmologists from the University of the Basque Country are searching for the model that best explains the evolution of the Universe.   view more (2008-10-22)

Running on rocket fuel
In the world of "cut and thrust," humans try to bank money to obtain financial security, and often form cooperatives to reduce risks and increase gains.   view more (2008-10-21)

Revealing the evolutionary history of threatened sea turtles
It's confirmed: Even though flatback turtles dine on fish, shrimp, and mollusks, they are closely related to primarily herbivorous green sea turtles.   view more (2008-10-16)

Scientists propose the creation of a new type of seed bank
While an international seed bank in a Norwegian island has been gathering news about its agricultural collection, a group of U.S. scientists has just published an article outlining a different kind of seed bank, one that proposes the gathering of wild species -- at intervals in the future --... view more (2008-10-16)

Gene expression in alligators suggests birds have 'thumbs'
The latest breakthrough in a 120 year-old debate on the evolution of the bird wing was published in the open-access journal PLoS ONE.   view more (2008-10-06)

Mysterious snippets of DNA withstand eons of evolution, Stanford study
Small stretches of seemingly useless DNA harbor a big secret, say researchers at the Stanford University School of Medicine. There's one problem: We don't know what it is.   view more (2008-10-02)

Short RNAs show a long history
MicroRNAs, the tiny molecules that fine-tune gene expression, were first discovered in 1993. But it turns out they've been around for a billion years.   view more (2008-10-02)

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)

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)

Luck gave dinosaurs their edge
T. rex and Triceratops: In the popular imagination, dinosaurs are extraordinary reptiles that ruled the world for over 160 million years. But Steve Brusatte, a doctoral student at Columbia University who is an affiliate of the American Museum of Natural History, and colleagues are challenging this... view more (2008-09-12)

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)

In spiders, size matters: Small males are more often meals
Female spiders are voracious predators and consume a wide range of prey, which sometimes includes their mates.   view more (2008-09-11)

MU Anthropologist Develops New Approach to Explain Religious Behavior
Without a way to measure religious beliefs, anthropologists have had difficulty studying religion. Now, two anthropologists from the University of Missouri and Arizona State University have developed a new approach to study religion by focusing on verbal communication, an identifiable behavior,... view more (2008-09-10)

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)
