Discovery: VPS4A enzyme plays a key role in release of HIV particles

Human Immunodeficiency Virus - which causes AIDS - invades human immune cells and causes them to produce new copies of the virus, which can then infect new cells.

Caltech students receive Lemelson-MIT Prize for innovative disease diagnostic technology works

California Institute of Technology graduate student Guoan Zheng is the recipient of the 2011 $30,000 Lemelson-MIT Caltech Student Prize.

Study finds synapses between retinal ganglion cells and starburst amacrine cells distributed asymmetrically

The sensory cells in the retina of the mammalian eye convert light stimuli into electrical signals and transmit them via downstream interneurons to the retinal ganglion cells which, in turn, forward them to the brain. The interneurons are connected to each other in such a way that the individual ganglion cells receive visual information from a circular area of the visual field known as the receptive field.

Bessel beam plane illumination microscopy reveals 3-D structures of living cells

A new microscope invented by scientists at Howard Hughes Medical Institute's Janelia Farm Research Campus will let researchers use an exquisitely thin sheet of light -- similar to that used in supermarket bar-code scanners -- to peer inside single living cells, revealing the three-dimensional shapes of cellular landmarks in unprecedented detail.

Scientist develops cryo-electron microscopy to clarify salmonellae structure

Bacteria like salmonellae infect their host cells by needle-shaped extensions which they create in large numbers during an attack. A group of Vienna-based scientists headed by Thomas Marlovits employed recently developed methods of cryo-electron microscopy and have been able to clarify the structure of this infection apparatus on the near-atomic scale.

Neuropathologist receives AAN Potamkin Prize for Alzheimer's disease research

The American Academy of Neurology has awarded the 2011 Potamkin Prize to Dennis Dickson, M.D., a neuropathologist at Mayo Clinic in Florida and the Robert E. Jacoby Professor for Alzheimer's Disease Research.

Professor develops optical technology that can detect, examine skin lesions

University of Rochester optics professor Jannick Rolland has developed an optical technology that provides unprecedented images under the skin's surface.

New technique reveals spatial structure of microbial community

Like people in cities, microbes often live in complex communities that contain many different microbial types. Also like us, microbes tend to gravitate to and "hang out" with certain other types in their community, more than with the rest. And sometimes, when opportunities arise, they move to more favorable locations.

Photodynamic therapy could be useful in eradicating tumor-associated lymphatic vessels

Tumor cells have several routes that enable them to move from the primary tumor to distant tissues, a process called metastasis. It is metastasis of the primary tumor that kills most cancer patients. One of the least studied routes of metastasis is the lymphatic system. Many tumors produce factors that promote the formation of new lymphatic vessels (lymphangiogenesis).

Rational use of heath care dollars for tonsillectomy

Without fanfare, hundreds of thousands of children surrender their tonsils to a surgeon's scalpel each year, usually to alleviate recurring infections and obstructive sleep problems. Most of the time, the snipped tonsils are sent to a pathologist, who looks for evidence of more serious medical problems, like unsuspected cancer.

Researchers receive NIH grant to develop computer models for pediatric airway problems

A multidisciplinary team of University of North Carolina at Chapel Hill researchers has been awarded a $3.6 million grant to develop computer models that will allow physicians to predict which treatments will work best in children with upper airway problems.

Painless, noninvasive biopsies with smart laser technology

Biopsies in the future may be painless and noninvasive, thanks to smart laser technology being developed at Michigan State University.

Connectome remains dynamic during development, says Scripps Research

Connected highways of nerve cells carry information to and from different areas of the brain and the rest of the nervous system. Scientists are trying to draw a complete atlas of these connections-sometimes referred to as the "connectome"-to gain a better understanding of how the brain functions in health and disease.

First three-dimensional projectome map of intact brain

It would be hard to understand how a city is organized without knowledge of the course of all of its streets. Scientists confront the same problem when trying to understand the functioning of the brain. In the case of vertebrates, we only have fragmentary knowledge of which nerve cells send their connections, so-called axons, into certain regions of the brain.

New investigative tool may explore intracellular processes with unprecedented clarity

Nongjian Tao and his colleagues at the Biodesign Institute at Arizona State University have pioneered a new technique capable of peering into single cells and even intracellular processes with unprecedented clarity.

OSC and RINCH offer support to speed discovery techniques of childhood diseases

Worried about her high fever and severe abdominal pain, a young couple rushed their baby daughter to the emergency department of Nationwide Children's Hospital. Physicians there found a lump in her belly, and, after examining X-rays and blood work, confirmed the parents' worst fear: their 18-month-old little girl had neuroblastoma, a rare pediatric cancer that involves the adrenal glands.

Malaria parasite caught in action on film for the first time

Australian researchers have managed to take pictures of microscopic malaria parasite as it invades a human red blood cell. This will provide a deeper understanding of the parasite’s behaviour and may help fight it. Up to 10% of the world’s population contract malaria every year and a million people, mostly pregnant women and children, die as a result of the parasite transmitted by infected mosquitoes.

Vaccine to prevent MRSA infections after bone and joint surgery

University of Rochester Medical Center orthopaedic scientists are a step closer to developing a vaccine to prevent life-threatening methicillin-resistant staphylococcus aureus (MRSA) infections following bone and joint surgery.
