New genetic clues on molecular evolution of Q fever pathogen

Scientists from the National Institute of Allergy and Infectious Diseases, Texas A&M Health Center, and the Virginia Bioinformatics Institute at Virginia Tech have uncovered genetic clues about why some strains of the pathogen Coxiella burnetii are more virulent than others.

The origin of species may be almost as random as a throw of the dice

Iosif Pinelis, a professor of mathematical sciences at Michigan Technological University, has worked out a mathematical solution to a biological puzzle: Why is the typical evolutionary tree so lopsided?

Discovery of new class of non-protein coding genes in mammals with key functions

A research team at the Broad Institute of Harvard and MIT and Beth Israel Deaconess Medical Center has uncovered a vast new class of previously unrecognized mammalian genes that do not encode proteins, but instead function as long RNA molecules.

Sociability traced to region of brain called amygdala

People with a genetic condition called Williams syndrome are famously gregarious. Scientists, looking carefully at brain function in individuals with Williams syndrome, think they may know why this is so.

Climate changes in Australia will increase dengue fever

As global warming raises concerns about potential spread of infectious diseases, a team of researchers has demonstrated a way to predict the expanding range of human disease vectors in a changing world.

New bone cement may prevent amputations

Old technologies, bone cement and a well known antibiotic, may effectively fight an emerging infection in soldiers with compound bone fractures, according to a study published online in the Journal of Orthopedic Research.

Although our genetics differ significantly, we all look alike...

The genetic variation within a species can be significant, but very little of that variation results in clear differences in morphology or other phenotypes.

More scientific evidence supporting Darwinian views of evolution

Studies at the University of Pennsylvania School of Medicine on brain electrical signaling offer a fresh perspective on vertebrate evolution, provide additional evidence supporting Darwinian views of evolution, and may also lead to more effective treatment of epileptic seizures in infants.

Ancient fish provides new piece in the jigsaw puzzle of human origins

In an article in the journal Nature, Uppsala researcher Martin Brazeau describes the skull and jaws of a fish that lived about 410 million years ago.

Domain duplication, divergence, and loss events in vertebrate Msx paralogs reveal phylogenomically informed disease markers

The work of Forsyth scientist Peter Jezewski, DDS, Ph.D., has revealed that duplication and diversification of protein regions ('modules') within ancient master control genes is key to the understanding of certain birth disorders.

Widespread antiviral drug use can accelerate the evolution of drug resistance in viruses

Influenza's ability to resist the effects of cheap and popular antiviral agents in Asia and Russia should serve as a cautionary tale about U.S. plans to use the antiviral Tamiflu in the event of widespread avian flu infection in humans, scientists say.

Bird flu becoming more resistant to antivirals

A new University of Colorado at Boulder study shows the resistance of the avian flu virus to a major class of antiviral drugs is increasing through positive evolutionary selection, with researchers documenting the trend in more than 30 percent of the samples tested.

Strong urologic surgeons perform cutting-edge minimally invasive surgery

Urologists at the University of Rochester Medical Center (URMC) are advancing the frontiers of minimally invasive surgery as they begin to introduce single-port access (SPA) surgery to the Rochester region.

New understanding of seizure behaviors and epilepsy

Two children have a seizure. One child never has another seizure. Twenty years later, the other child has a series of seizures and is diagnosed with epilepsy.

Biologist finds plant polymerases IV and V are really variants of polymerase II

It's a little like finding out that Superman is actually Clark Kent. A team of biologists at Washington University in St. Louis has discovered that two vital cellular components, nuclear RNA Polymerases IV and V (Pol IV and V), found only in plants, are actually specialized forms of RNA Polymerase II, an essential enzyme of all eukaryotic organisms, including humans.
