Scientists show how "junk" DNA may be a major driver for evolution

In a paper published in Genome Research on Nov. 4, scientists at the Genome Institute of Singapore (GIS) report that what was previously believed to be "junk" DNA is one of the important ingredients distinguishing humans from other species.

Research shows why parents are born and not made

New research reveals for the first time that the different roles of mothers and fathers are influenced by genetics.

Biologists identify genes that prevent changes in physical traits due to environmental changes

New York University biologists have identified genes that prevent physical traits from being affected by environmental changes.

No need for RNA

Not all enzymes that are assumed to require an RNA component in order to function do actually contain RNA. This surprising discovery was made during a project supported by the Austrian Science Fund FWF that focussed on the enzyme RNase P.

Bacteria can directly cause human blood and plasma to clot

Bacteria can directly cause human blood and plasma to clot - a process that was previously thought to have been lost during the course of vertebrate evolution, according to new research at the University of Chicago, National Institute of Allergy and Infectious Diseases, and Institut Pasteur in Paris. Their findings will be published online Nov. 2 in Nature Chemical Biology.

Researchers discover how Sonic hedgehog gene controls brain development

University of Pennsylvania School of Medicine researchers have discovered how the expression of the Sonic hedgehog gene is regulated during brain development and how mutations that alter this process cause brain malformations. The results appear online this month in Nature Genetics.

Novel cell division mechanism discovered

A novel cell division mechanism has been discovered in a microorganism that thrives in hot acid. The finding may also result in insights into key processes in human cells, and in a better understanding of the main evolutionary lineages of life on Earth. The study is published today in the online version of the journal of the American National Academy of Sciences, PNAS.

How we see and understand the three-dimensional structure of objects

A team of Johns Hopkins University neuroscientists has discovered patterns of brain activity that may underlie our remarkable ability to see and understand the three-dimensional structure of objects.

Sensitive ultrasound to spot early-stage cancer

European researchers have developed highly sensitive ultrasound equipment that can detect tiny quantities of reflective microbubbles engineered to stick to specific tumour cells. The technique should pick up tumours early and improve patients' chances of survival.

Getting the flu early may protect against worse one later

New evidence about the worldwide influenza pandemic of 1918-1919 indicates that getting the flu early protected many people against a second deadlier wave, an article co-authored by an NIH epidemiologist concludes.

NIH funds two new centers for imaging technology for neurodegenerative disorders and software for protein analysis

The National Center for Research Resources (NCRR), a part of the National Institutes of Health (NIH), announced today it will provide up to an estimated $11 million over the next five years to create two new Biomedical Technology Research Centers (BTRCs) that will provide researchers nationwide with access to specialized research tools, training and state-of-the-art equipment.

Addex Parkinson's product progressing in early clinical trials

Addex Pharmaceuticals has announced that it has completed the first part of a two-part Phase I clinical trial to evaluate the newly developed modified release formulation of ADX48621. ADX48621 is scheduled to start a Phase IIa proof of concept study for the treatment of levodopa associated dyskinesia in Parkinson's disease during the first half of 2009.

Altruistic behaviour can be sexually attractive to others

Displays of altruism or selflessness towards others can be sexually attractive in a mate. This is one of the findings of a study carried out by biologists and a psychologist at The University of Nottingham.

Discovery of gene variant for cleft lip

About 20 percent of isolated cleft lip, one of the world's most common birth defects, may be due to a one-letter difference in the DNA sequence of a gene involved in facial development, researchers supported by the National Institutes of Health report.

Short RNAs show a long history

MicroRNAs, the tiny molecules that fine-tune gene expression, were first discovered in 1993. But it turns out they've been around for a billion years.

Tuberculosis bacterium uses its sugar coat to sweeten its chances of living in lungs

Common strains of tuberculosis-causing bacteria have hijacked the human body's immune response to play tricks on cells in the lungs, scientists say.

Genetic fishing expedition yields surprising catch important to mammals

Johns Hopkins investigators report the discovery of master controllers of a gene critical to human and all mammalian development by trawling, implausibly enough, through anonymous genetic sequences using tiny zebrafish embryos.

Roman York skeleton could be one of Britain's earliest victims of tuberculosis

The skeleton of a man discovered by archaeologists in a shallow grave on the site of the University of York's campus expansion could be that of one of Britain's earliest victims of tuberculosis.

Infectious heart disease death rates rising again say scientists

Infectious heart disease is still a major killer in spite of improvements in health care, but the way the disease develops has changed so much since its discovery that nineteenth century doctors would not recognise it, scientists heard today (Thursday 11 September 2008) at the Society for General Microbiology's Autumn meeting being held this week at Trinity College, Dublin.
