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.

In mice, anxiety is linked to immune system

In the first study ever to genetically link the immune system to normal behavior, scientists at Rockefeller and Columbia universities show that mast cells, known as the pharmacologic bombshells of the immune system, directly influence how mice respond to stressful situations.

New technique sees into tissue at greater depth, resolution

By coupling a kicked-up version of microscopy with gold nanoparticles, investigators at Duke University have been able to peer so deeply into living tissue that they can see molecules interacting.

Healing process found to backfire in idiopathic pulmonary fibrosis patients

A mechanism in the body which typically helps a person heal from an injury, may actually be causing patients with idiopathic pulmonary fibrosis (IPF) to get worse, researchers at the National Institute of Environmental Health Sciences (NIEHS), a part of the National Institutes of Health (NIH), and their collaborators have found.

Universal test for genetic diseases in unborn children in the pipeline

A team of British scientists have developed a ground-breaking new test to screen for genetic diseases in unborn children.

New drugs the next casualty of the credit crunch

Scientists at an international conference have been warned that the next casualty of the credit crunch could be new drugs.

Human rhinovirus found to manipulate genes

Sneezing, runny nose and chills? You might blame the human rhinovirus (HRV), which causes 30 to 50 percent of common colds. But in reality, it's not the virus itself but HRV's ability to manipulate your genes that is the true cause of some of the most annoying cold symptoms.

Simple gene-based blood test, quicker, more accurate evaluation for cystic fibrosis

Researchers at National Jewish Health have identified a simple gene-based blood test that more accurately and quickly measures cystic fibrosis patients' response to therapy than current tests.

Newly discovered mechanism can explain the Beckwith-Wiedemann syndrome

Researchers from Uppsala University have discovered a mechanism that silences several genes in a chromosome domain. The findings, published in today's on-line issue of Molecular Cell, have implications in understanding the human disorder Beckwith-Wiedemann syndrome.

Scientists discover how a well-known protein repairs broken DNA ends

During the life cycle of our cells, a minefield of environmental and biological assaults can lead to double-stranded DNA breaks, the most lethal and dangerous form of DNA damage. Now, in research published online this week in Nature, Rockefeller University scientists reveal that when these breaks occur, a protein called 53BP1 helps repair them by mobilizing their dangly DNA ends - findings that uncover a previously unknown aspect of how double-stranded breaks can get fixed.

A new role for a critical DNA repair molecule in the immune system

The human immune system is a brilliantly adaptable weapon against foreign invaders. But it all depends on the work of specialized cells called lymphocytes that have made a risky evolutionary gambit to mutate their own DNA.

FDA approves Boston Scientific's carotid artery stent

Boston Scientific Corporation has announced that the U.S. Food and Drug Administration (FDA) has approved its Carotid WALLSTENT Monorail Endoprosthesis for the treatment of patients with carotid artery disease who are at high risk for surgery.

Self assembling "organic wires"

From pacemakers constructed of materials that so closely mimic human tissues that a patient's body can't discern the difference to devices that bypass injured spinal cords to restore movement to paralyzed limbs, the possibilities presented by organic electronics read like something from a science fiction novel.

Leukaemia drug may reverse multiple sclerosis brain damage

Scientists in Britain say a drug which was developed to treat leukaemia may also be a powerful new weapon against multiple sclerosis (MS).

Scientists grow prostates from mouse stem cells

A team of molecular biologists in the U.S. have grown complete prostates derived from stem cells in the prostates of mice and they say the experiment represents a big step towards regenerating organs from a patients' own cells.

Gene mutation in worms could further understanding of alcoholism in humans

The work follows a study carried out by Oregon Health and Science University, which suggested a link between a gene mutation in mice and tolerance to alcohol. Researchers at Liverpool have investigated this in worms, looking specifically at the role the gene plays in communication between cells in the nervous system.
