Brain's 'hate circuit' identified

People who view pictures of someone they hate display activity in distinct areas of the brain that, together, may be thought of as a 'hate circuit', according to new research by scientists at UCL (University College London).

Gene against bacterial attack unravelled

Dutch researcher Joost Wiersinga from AMC Medical Centre in Amsterdam has unravelled a genetic defence mechanism against the lethal bacteria Burkholderia pseudomallei. The research is the next step towards a vaccine against this bacterium suitable for bioweapons.

Review of health benefits of grape polyphenols

A growing body of research data suggests that consuming foods rich in polyphenols from grapes - including red wine - helps reduce the risk of heart disease, according to a review article in the November issue of Nutrition Research.

New strategy to treat human infections caused by the yeast Candida albicans

Researchers at Georgetown University Medical Center (GUMC) have successfully tested a genetic strategy designed to improve treatment of human infections caused by the yeast Candida albicans, ranging from diaper rash, vaginitis, oral infections (or thrush which is common in HIV/AIDS patients), as well as invasive, blood-borne and life-threatening diseases.

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 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.

Gates Foundation grant to help prevent deaths in Africa by improving antibiotic access

The Alliance for the Prudent Use of Antibiotics (APUA) has announced a $1.37 million grant from the Bill & Melinda Gates Foundation, to explore ways of reducing millions of preventable deaths from severe respiratory and diarrheal infections in Africa. This project was announced in conjunction with a colloquium at the annual ICAAC/IDSA meeting warning of increasing antibiotic resistance.

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.

New molecules with many branches will help unleash potential of nanotechnology

Materials science and the pharmaceutical industry could soon be revolutionized by emerging nanotechnologies based on designer molecules with long complex tree-and branch structures. Such molecules offer almost limitless scope for design of bespoke compounds for specific applications in disease therapy, for novel materials such as resins, as well as electronic displays, and energy storage. Almost every field involving design and synthesis of chemical compounds will be transformed by the arrival of technologies allowing nanoscale design of these branched molecules, known as hyperbranched polymers.

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.

Grant funds research on environmental link to breast cancer

A foundation that funds research that examines the environmental causes of breast cancer has awarded a grant to a post-doctoral associate at the University of Rochester Medical Center.

Gene find sheds light on motor neuron diseases like amyotrophic lateral sclerosis

Scientists have identified a gene in mice that plays a central role in the proper development of one of the nerve cells that goes bad in amyotrophic lateral sclerosis, or Lou Gehrig's disease, and some other diseases that affect our motor neurons.

Aires Pharmaceuticals signs license agreement with NIH

Aires Pharmaceuticals Inc. today announced the signing of an exclusive license agreement with the U.S. National Institutes of Health for the patented use of a nitric oxide prodrug to treat cardiopulmonary conditions.

Bird flu appears again in Hong Kong

Bird flu is in the news again following the revelation that a dead crow found recently at a local community in Hong Kong was confirmed to be H5N1 positive.

People lacking essential antioxidants and sunlight more likely to develop advanced macular degeneration

People who lack essential antioxidants, and who have high levels of sunlight exposure, have a higher risk of developing advanced macular degeneration (AMD), according to a study published today in the journal Archives of Ophthalmology. AMD is the leading cause of poor vision in the UK.

Sun-damaged skin responds well to laser treatment

Researchers at the University of Michigan Health System Department of Dermatology have found scientific evidence that the appearance of sun-damaged skin may be improved by treatment with a topical product that increases the skin's sensitivity to light, followed by laser therapy.

Beyond recognizing odors, a single neuron controls reactions

Babies will smile when they catch the scent of vanilla, but a whiff of rotting meat will send them into fits. From people to mice and flies to worms, animals of all kinds are born with likes and dislikes thanks to the evolutionary wisdom collected in their genes. But new research shows that some preferences are still surprisingly flexible at even the most basic level - that of the sensory neuron itself - and that our nervous system may be even more adaptable than we thought.

Bristol scientist puts the brakes on breast cancer

Why do breast cells grow out of control? The answer could be a step closer thanks to a grant of around £200,000 from one of the UK's leading breast cancer research charities, Breast Cancer Campaign, to University of Bristol scientist, Dr Claire Perks.
