Molecular biology fills gaps in knowledge of bat evolution

One in five mammals living on Earth is a bat, yet their evolutionary history is largely unknown because of a limited fossil record and conflicting or incomplete theories about their origins and divergence. Now, a research team including University of California, Riverside Biology Professor Mark Springer, has published a paper in the Jan. 28 issue of the journal Science that uses molecular...

Same mutation aided evolution in many fish species, Stanford study finds

After decades of laboratory work studying how animals evolve, researchers sometimes need to put on the hip waders, pull out the fishing net and go learn how their theory compares to the real world. According to a Stanford University School of Medicine study published in the March 25 issue of Science, Mother Nature is more predictable than lab experiments suggest. In a diverse group of fish...

Researchers trace evolution to relatively simple genetic changes

In a stunning example of evolution at work, scientists have now found that changes in a single gene can produce major changes in the skeletal armor of fish living in the wild. "Our motivation is to try to understa...

Family trees of ancient bacteria reveal evolutionary moves

A geomicrobiologist at Washington University in St. Louis has proposed that evolution is the primary driving force in the early Earth's development rather than physical processes, such as plate tectonics. Carrine Blank, Ph.D., Washington University assistant professor of geomicrobiology in the Department of Earth & Planetary Sciences in Arts & Sciences, studying Cyanobacteria ?bac...

Scientists discover how fish evolved to float at different sea depths

Scientists at the University of Liverpool have discovered how fish have evolved over the last 400 million years to stay motionless at different water depths. A research team led by Dr Michael Berenbrink, a Comparative Physiologist at the School of Biological Sciences, has revealed how modern fish, such as pike and cod, have developed a way of floating at certain water levels using a gas-f...

Nitric oxide involved in high blood pressure

High blood pressure causes inactivation of nitric oxide, a hormone involved in blood pressure control which worsens the problem. If high blood pressure is left untreated, it does not stay at one elevated level, but tends to spiral out of control. According to the researchers at the University of Texas, this study was conducted on rats and found that nitric oxide, which helps control blood...

Lower surgical volume linked to higher death rate

Paediatric heart units that carry out a high number of operations have lower deaths rates than those with a low volume of cases. David Spiegelhalter, a scientist at the Institute of Public Health in Cambridge, analysed voluntary surgical returns and hospital episode statistics relating to 12 hospitals carrying// out heart surgery on children from 1991 to 1995. Dr Spiegelhalter found t...
