Research shows rare parasitic disease is transmitted by gay men

A rare parasitic disease, which normally only is transmitted by contaminated water, has been shown to be transmitted by gay sex between hiv-positive men. In the industrial world the disease is virtually absent, but from now on that could change.

Studies examine interaction of ribosome with molecular partners

Two new studies reveal in unprecedented detail how the ribosome interacts with other molecules to assemble new proteins and guide them toward their destination in biological cells. The studies used molecular dynamics flexible fitting (MDFF) to examine the interaction of the ribosome with two prominent molecular partners.

Image of a water flea wins top prize in the 2009 Olympus BioScapes Digital Imaging Competition

A glowing, eerily beautiful image of a water flea with its radiant green "crown of thorns" took top prize in the 2009 Olympus BioScapes Digital Imaging Competition®, the world's foremost forum for showcasing microscope photos and movies of life science subjects. Dr. Jan Michels, a zoologist at the University of Albrecht, Kiel, Germany, took top honors for the image of a water flea, with its defensive "crown of thorns" to protect it against predators. The image reveals not only the exoskeleton, but also interior detail down to the nuclei within its cells, seen as tiny, glowing blue dots. This

Researchers develop new device with nano-sized features to grab cancer cells

Just as fly paper captures insects, an innovative new device with nano-sized features developed by researchers at UCLA is able to grab cancer cells in the blood that have broken off from a tumor.

IBM led computing team achieves major advances in large-scale cortical simulation

Today at SC 09, the supercomputing conference, IBM announced significant progress toward creating a computer system that simulates and emulates the brain's abilities for sensation, perception, action, interaction and cognition, while rivaling the brain's low power and energy consumption and compact size.

Scientists describe how HIV assemble at the membrane of infected cells and are released to attack healthy cells

Although recent advances have raised hopes that a protective vaccine can be developed, acquired immunodeficiency syndrome (AIDS) remains a major public health problem. Much has been learned about HIV-1, the virus that causes the disease.

NIDA supports new drug detection research

Every time a person snorts cocaine, it doesn't just go to his or her head: It also provokes a response in the immune system, creating special biomolecules that may serve as a permanent record of each exposure.

HFSP grant to develop molecular probes to study "cellular GPS" system

An international group of researchers from Carnegie Mellon University, Goettingen Medical School in Germany and the University of Cambridge in the United Kingdom have received a Human Frontiers Science Program (HFSP) grant to develop molecular probes that will help researchers better understand the "cellular GPS" system that guides neurons to create a properly wired nervous system.

New breast reconstruction surgery for women

Since her teens, Jennifer Jablon had watched family members deal with breast cancer during their 40s, 50s, and 60s. She wondered whether it would be her fate too.

Scientists identify new behavioral traits of immune cells; findings may help in understanding complex diseases

In diseases such as multiple sclerosis, cells of the immune system infiltrate the brain tissue, where they cause immense damage. For many years, it was an enigma as to how these cells can escape from the bloodstream. This is no trivial feat, given that specialized blood vessels act as a barrier between the nervous system and the bloodstream.

Micro-injector may help rapid development of new generation of drugs

It's no bigger than a stamp packet but it has the potential to allow rapid development of a new generation of drugs and genetic engineering organisms, and to better control in-vitro fertilization.

Laser-scanning microscope records brain activity in freely moving animals

The majority of our life is spent moving around a static world and we generate our impression of the world using visual and other senses simultaneously. It is the ability to freely explore our environment that is essential for the view we form of our local surroundings.

Men with lower cholesterol less likely to develop high-grade prostate cancer

Men with lower cholesterol are less likely than those with higher levels to develop high-grade prostate cancer - an aggressive form of the disease with a poorer prognosis, according to results of a Johns Hopkins collaborative study.

Strong alkaline substances can damage teeth

It has long been known that acids can erode tooth enamel but a new Swedish study from the Sahlgrenska Academy at the University of Gothenburg, Sweden, shows that strong alkaline substances can damage teeth too - substances with high pH values can destroy parts of the organic content of the tooth, leaving the enamel more vulnerable.

Arizona State University researchers to use laws of physics for cancer research

Instead of killing cancer cells, researchers at Arizona State University will use the laws of physics to figure out how to control them. And, rather than treating cancer as a disease and seeking a cure, ASU scientists will view cancer cells as physical objects and study them the way a physicist would, using simple variables like temperature, pressure and force.

Protein crucial for insulin regulation may play a role in diabetes

A cellular protein from a family involved in several human diseases is crucial for the proper production and release of insulin, new research has found, suggesting that the protein might play a role in diabetes.

Scientists demonstrate how second set of cells carry signals from the inner ear to the brain

Deep in the ear, 95 percent of the cells that shuttle sound to the brain are big, boisterous neurons that, to date, have explained most of what scientists know about how hearing works. Whether a rare, whisper-small second set of cells also carry signals from the inner ear to the brain and have a real role in processing sound has been a matter of debate.
