Scientists sequence ten variants of E. coli O104:H4 outbreak strain across the world

Ten variants of the deadly Escherichia coli strain that hit Germany in May 2011 have been sequenced across the world. The unprecedented level of collaboration across the scientific community should give insight into how the outbreak arose, says a scientist at the Society for General Microbiology's Autumn Conference 2011.

Scientists discover highly conserved mechanism governing brain development

If you think today's political rhetoric is overheated, imagine what goes on inside a vertebrate embryo. There, two armies whose agendas are poles apart, engage in a battle with consequences much more dire than whether the economy will recover---- they are battling for whether you (or frogs or chickens) will have a forebrain.

Scientists uncover one of the benefits of non-monogamous relationships

It's all about the grandkids! That's what a team led by an Indiana University biologist has learned about promiscuous female birds and why they mate outside their social pair.

Study: Growth hormone helps regenerate damaged hair cells in zebrafish ear

Loud noise, especially repeated loud noise, is known to cause irreversible damage to the hair cells inside the cochlea and eventually lead to deafness. In mammals this is irreversible, however both birds and fish are able to re-grow the damaged hair cells and restore hearing.

Discovery in rare disease may shed light on common causes of blindness

In a rare eye disease, the retina degenerates because light-receiving cells fail to regenerate, research led by a student at Case Western Reserve University School of Medicine shows.

Chromatin might have another life as direct signaling molecule

Chromatin - the intertwined histone proteins and DNA that make up chromosomes - constantly receives messages that pour in from a cell's intricate signaling networks: Turn that gene on. Stifle that one. But chromatin also talks back, scientists at The University of Texas MD Anderson Cancer Center report today in the journal Cell, issuing orders affecting a protein that has nothing to do with chromatin's central role in gene transcription - the first step in protein formation.

New genetic screening program for families at high risk of colorectal cancer

UT Southwestern Medical Center has developed a new lifesaving genetic screening program for families at high risk of contracting colorectal cancer, a deadly yet highly preventable form of cancer.

UVA researchers develop 3-D model to visualize early growth of human breast tissue

University of Virginia researchers have developed a revolutionary three-dimensional model that allows them to visualize how breast tissue grows in its earliest stages, giving them the closest look ever at the very beginnings of breast cancer.

Walnut-containing diet could reduce risk of breast cancer

The risk of breast cancer dropped significantly in mice when their regular diet included a modest amount of walnut, Marshall University researchers report in the journal Nutrition and Cancer.

Ancient antibiotic resistance findings leads experts to stress need to use antibiotics sparingly

"An analysis of 30,000-year-old bacteria whose DNA has been recovered from the Yukon permafrost shows that they were able to resist antibiotics," providing "the first direct evidence that antibiotic resistance is a widespread natural phenomenon that preceded the modern medical use of antibiotics," according to a study in Thursday's issue of the journal Nature, the New York Times reports.

Scientists discover genetic cause of extreme thinness

Scientists have discovered a genetic cause of extreme thinness for the first time, in a study published today in the journal Nature.

UTHealth inaugurates new center for autoimmune and inflammatory diseases research

The University of Texas Health Science at Houston (UTHealth) announced the opening of a center devoted to researching and treating diseases associated with malfunctioning immune systems.

Two ALS-associated genes work in tandem to support long-term survival of motor neurons

Although several genes have been linked to amyotrophic lateral sclerosis (ALS), it is still unknown how they cause this progressive neurodegenerative disease. In a new study, Columbia University Medical Center (CUMC) researchers have demonstrated that two ALS-associated genes work in tandem to support the long-term survival of motor neurons.

Insight into molecular basis of Enhanced S-Cone Syndrome

A new research report published in The FASEB Journal will help ophthalmologists and scientists better understand a rare genetic disease that causes increased susceptibility to blue light, night blindness, and decreased vision called Enhanced S-Cone Syndrome or Goldman-Favre Syndrome.

Bowel cancer, coffee and diabetes: Two new studies

Australian researchers have identified a link between type 2 diabetes in men and a significantly increased risk of bowel cancer, triggering calls for diabetics to have regular checks.

Sunscreen pills from coral

Researchers have found that coral does not suffer from sunburn despite living in shallow water in tropical areas, because it is able to produce its own “natural sunscreen”. By studying the compounds which protect it from UV rays, researchers hope to develop a tablet which can protect human skin and eyes without the need for dark glasses or sun cream. Scientists from King's College London said the first sunscreen pill could be available within five years.

Stanford method identifies essential regions of Caulobacter's genome

A team at the Stanford University School of Medicine has cataloged, down to the letter, exactly what parts of the genetic code are essential for survival in one bacterial species, Caulobacter crescentus.

Gene variants can cut risk of Parkinson's disease

An international team of researchers led by neuroscientists at Mayo Clinic in Florida has found a genetic variation they say protects against Parkinson's disease. The gene variants cut the risk of developing the disease by nearly 20 percent in many populations.

Parental stress strongly associated with DNA methylation in children

Researchers at the University of British Columbia and the Child & Family Research Institute have shown that parental stress during their children's early years can leave an imprint on their sons' or daughters' genes - an imprint that lasts into adolescence and may affect how these genes are expressed later in life.

Study may help explain plague's rapid evolution and aid in development of therapeutics

In the evolutionary blink of an eye, a bacterium that causes mild stomach irritation evolved into a deadly assassin responsible for the most devastating pandemics in human history. How did the mild-mannered Yersinia pseudotuberculosis become Yersinia pestis, more commonly known as the Plague?
