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.

Procalcitonin: A valuable predicator for lethal respiratory failure

High levels or persistent elevation of PCT in patients with severe pneumonia usually results in death. According to a study in Respirology published by Wiley-Blackwell, Procalcitonin (PCT) levels in patients are indicative of survival rates, proving to be a valuable prognostic factor of Acute Respiratory Distress Syndrome (ARDS).

Scientists paint-viruses with proteins to track and treat viral disease and evolution

Biologists from Austria and Singapore developed a technique that adds a new twist on the relationship between biology and art. In an article recently published online in The FASEB Journal and scheduled for the August 2008 print issue, these researchers describe how they were able to coat-or paint-viruses with proteins.

A loving partner can save your skin

Even couples that have been together for years may be embarrassed to let a spouse or partner see their less than perfect bodies naked in bright light. That shyness can hamper a couple's willingness to do total body skin exams on each other to check for a new or recurring melanoma. Melanoma, the most deadly form of skin cancer, can appear in more than one spot so these checks are important.

Human vision inadequate for research on bird vision

The most attractive male birds attract more females and as a result are most successful in terms of reproduction. This is the starting point of many studies looking for factors that influence sexual selection in birds. However, is it reasonable to assume that birds see what we see? In a study published in the latest issue of American Naturalist, Uppsala researchers show that our human vision is not an adequate instrument.

Ancient protein myosin 2 offers clues to killer condition

More than 600 million years of evolution has taken two unlikely distant cousins - turkeys and scallops - down very different physical paths from a common ancestor. But University of Leeds researchers have found that a motor protein, myosin 2, remains structurally identical in both creatures.

Model shows how mutation tips biochemistry to cause Alzheimer's

Your fate can be determined by tiny events. Imagine you live in the city and you walk everywhere to get exercise - you are healthy and not afraid of getting mugged. You almost never eat breakfast so you don't stop at the donut shop on the way to work, until one day the manager replaces the girl at the counter with her pretty red-haired younger sister. This seemingly unimportant change in your world is just enough to overcome your ability to resist high-fat temptation. A million donuts later, your cholesterol level surges and then your heart gives out. Curse you, little red-haired girl!

Scientists identify key roadblock to gene expression

A team of scientists has provided, for the first time, a detailed map of how the building blocks of chromosomes, the cellular structures that contain genes, are organized in the fruit fly Drosophila melanogaster. The work identifies a critical stop sign for transcription, the first step in gene expression, and has implications for understanding how the AIDS virus regulates its genes. The findings will be published in the 15 May 2008 issue of the journal Nature

Males and females have essentially unisex brains - at least in flies!

Research by Yale scientists shows that males and females have essentially unisex brains - at least in flies - according to a recent report in Cell designed to identify factors that are responsible for sex differences in behavior.

New findings challenge conventional ideas on evolution of human diet, natural selection

New findings suggest that the ancient human "cousin" known as the "Nutcracker Man" wasn't regularly eating anything like nuts after all.

Teenage health in Europe

After three years of work, the EU funded research programme HELENA has revealed its initial results. It concludes that amongst European adolescents, approximately 27% of males and 20% of females are either overweight or obese. It also reveals for the first time at European level, food intake and physical activity patterns for adolescents.
