COMT gene variation affects fear processing, anxiety

Inborn differences may help explain why trauma gives some people bad memories and others the nightmare of post-traumatic stress. Scientists in Germany and the United States have reported evidence linking genes to anxious behavior. The findings appear in the August issue of Behavioral Neuroscience, published by the American Psychological Association.

USPTO issues patent for methodologies for abating a broad range of allergens, pathogens, viruses, bacteria

The United States Patent & Trademark Office issued a patent for an environmentally "Green" low cost process that eliminates the effects of a broad range of pollutants using oxidants.

Human brains pay a price for being big

Metabolic changes responsible for the evolution of our unique cognitive abilities indicate that the brain may have been pushed to the limit of its capabilities. Research published today in BioMed Central's open access journal Genome Biology adds weight to the theory that schizophrenia is a costly by-product of human brain evolution.

Survival of the fittest: even cancer cells follow the laws of evolution

Scientists from The Institute of Advanced Studies at Princeton and the University of California discovered that the underlying process in tumor formation is the same as for life itself-evolution.

Olympic doping - scientists race to stay ahead of the drug-taking and genetic manipulation

The race to ensure that scientists stop drug-taking athletes from damaging sport by using performance enhancing drugs or undergoing genetic manipulation is a constant challenge, according to a major four-decade review by three of the World's leading experts on doping in sport.

Genome sequencing study reveals new genetic typhoid fever signatures

For the first time, next-generation DNA sequencing technologies have been turned on typhoid fever - a disease that kills 600,000 people each year. The results will help to improve diagnosis, tracking of disease spread and could help to design new strategies for vaccination.

Knowing means simplifying: gluten-free diet alone is enough to cure the bones of pediatric patients with celiac disease

Individuals affected by celiac disease (gluten intolerance) often present an altered calcium (Ca2+) metabolism that can cause osteopenia, a bone mass decrease due to the impaired adsorption of this mineral, which can lead to osteoporosis (in 35-85% of the cases).

Study outlines measures to limit effects of pandemic flu on nursing homes

The greatest danger in a pandemic flu outbreak is that it could spread quickly and devastate a broad swath of people across the United States before there is much of a chance to react. The result could be a nation brought to its knees by a disease run rampant.

Advances in RNA research

RNA, the transporter of genetic information within the cell, has emerged from the shadow of DNA to become one of the hottest research areas of molecular biology, with implications for many diseases as well as understanding of evolution. But the field is complex, requiring access to the latest equipment and techniques of imaging, gene expression analysis and bioinformatics, as well as cross-pollination between multiple scientific disciplines.

Scientists generate the most precise map of genetic recombination ever

Genetic recombination, the process by which sexually reproducing organisms shuffle their genetic material when producing germ cells, leads to offspring with a new genetic make-up and influences the course of evolution.

Brain food - what we eat affects our intelligence

New research findings published online in The FASEB Journal provide more evidence that if we get smart about what we eat, our intelligence can improve. According to MIT scientists, dietary nutrients found in a wide range of foods from infant formula to eggs increase brain synapses and improve cognitive abilities.

Scientists discover how an injured embryo can regenerate itself

More than 80 years have passed since the German scientist Hans Spemann conducted his famous experiment that laid the foundations for the field of embryonic development. After dividing a salamander embryo in half, Spemann noticed that one half - specifically, the half that gives rise to the salamander's 'belly' (ventral) starts to wither away.

Women have not adapted to casual sex, shows research

The sexual and feminist revolutions were supposed to free women to enjoy casual sex just as men always had. Yet according to Professor Anne Campbell from Durham University in the UK, the negative feelings reported by women after one-night stands suggest that they are not well adapted to fleeting sexual encounters. Her findings are published online in the June issue of Springer's journal, Human Nature.

Evolution may have lumbered humans with allergy problems

Scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have discovered how evolution may have lumbered humans with allergy problems.

ADHD an advantage for nomadic tribesmen

A propensity for attention deficit hyperactivity disorder (ADHD) might be beneficial to a group of Kenyan nomads, according to new research published in the open access journal BMC Evolutionary Biology.

Complex synapses drove brain evolution

One of the great scientific challenges is to understand the design principles and origins of the human brain. New research has shed light on the evolutionary origins of the brain and how it evolved into the remarkably complex structure found in humans.

New grant to enable University of Rochester to increase HIV research by 25 percent

The University of Rochester today announced that the National Institutes of Health (NIH) has awarded a team of more than 50 researchers a five-year, $3.2 million grant.

Personal genomes may lead to personalized vitamin supplements

As the cost of sequencing a single human genome drops rapidly, with one company predicting a price of $100 per person in five years, soon the only reason not to look at your "personal genome" will be fear of what bad news lies in your genes.

Scientists sequence first female DNA

Geneticists of Leiden University Medical Centre (LUMC) are the first to determine the DNA sequence of a woman. She is also the first European whose DNA sequence has been determined. This has been announced by the researchers this morning, during a special press conference at 'Bessensap', a yearly meeting of scientists and the press in the Netherlands.

New cheaper method for mapping disease genes

Scientists at the Swedish medical university Karolinska Institutet have developed a new DNA-sequencing method that is much cheaper than those currently in use in laboratories. They hope that this new method will make it possible to map disease genes in large patient groups, which in turn can mean quicker breakthroughs for new treatments for a wide variety of diseases.
