MIT researchers unravel bacteria communication pathways
MIT researchers have figured out how bacteria ensure that they respond correctly to hundreds of incoming signals from their environment. view more (2008-06-13)
Annual plants may cope with global warming better than long-living species
Countering Charles Darwin's view that evolution occurs gradually, UC Irvine scientists have discovered that plants with short life cycles can evolutionally adapt in just a few years to climate change. view more (2007-01-09)
Unraveling where chimp and human brains diverge
Six million years ago, chimpanzees and humans diverged from a common ancestor and evolved into unique species. view more (2006-11-14)
Scientists complete DNA sequencing and analysis of multiple fruit fly genomes
In one of the first large-scale comparisons of multiple animal genomes, scientists at the Broad Institute of MIT and Harvard, the Computer Science and Artificial Intelligence Laboratory (CSAIL) at MIT, and many collaborating institutions, have analyzed the genomes of twelve species of the fruit fly Drosophila to reveal insights on the evolution of... view more...

Wastewater from the canning industry is not harmful to the agricultural soil
Irrigation with wastewater from the canning industry is not harmful to the quality of agricultural soil and may even, in some cases, improve it. This is the conclusion of Iñigo Abdón Virto Quecedo in his PhD thesis defended at the Public University of Navarre. view more (2004-12-22)
Boosting its infectivity turns benign virus into good gene therapy carrier for cystic fibrosis
Researchers from the University of California, Berkeley, and the University of Iowa have turned a relatively benign virus into a highly infectious form that is ideal as a carrier for gene therapy. view more (2009-02-17)
The difference between fish and humans: scientists answer century-old developmental question
Embryologists at UCL (University College London) have helped solve an evolutionary riddle that has been puzzling scientists for over a century. view more (2007-10-11)
How Increased UV Exposure Impacts Plants
As the first plant life to emerge from the water and develop on dry earth, bryophytes offer a unique opportunity for researchers to understand the development of protections against ultraviolet radiation. view more (2009-03-10)
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, instead of speculating about alleged beliefs in the... view more...

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)
Scripps scientists develop first examples of RNA that replicates itself indefinitely
Findings could inform biochemical questions about how life began. Now, a pair of Scripps Research Institute scientists has taken a significant step toward answering that question. The scientists have synthesized for the first time RNA enzymes that can replicate themselves without the help of any proteins or other cellular components, and the... view more... (2009-01-12)
Anthropologist's studies of childbirth bring new focus on women in evolution
Contrary to the TV sitcom where the wife experiencing strong labor pains screams at her husband to stay away from her, women rarely give birth alone. There are typically doctors, nurses and husbands in hospital delivery rooms, and sometimes even other relatives and friends. Midwives often are called on to help with births at home. view more (2009-02-18)
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 from the University of Florida. 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 galaxies. view more (2007-07-10)
Ocean's journey towards the center of the Earth
A Monash geoscientist and a team of international researchers have discovered the existence of an ocean floor was destroyed 50 to 20 million years ago, proving that New Caledonia and New Zealand are geographically connected. view more (2009-03-05)
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 certain genetic disorders, such as hemophilia. view more (2005-07-01)
Beaked, bird-like dinosaur tells story of finger evolution
Scientists have discovered a unique beaked, plant-eating dinosaur in China. The finding, they say, demonstrates that theropod, or bird-footed, dinosaurs were more ecologically diverse in the Jurassic period than previously thought, and offers important evidence about how the three-fingered hand of birds evolved from the hand of dinosaurs. view more (2009-06-18)
