Breakthrough in nanotechnology could make laboratory tests more sensitive

A laboratory test used to detect disease and perform biological research could be made more than 3 million times more sensitive, according to researchers who combined standard biological tools with a breakthrough in nanotechnology.

Glia seem to play two opposing roles in protecting nerve cells from damage

A protein produced by the central nervous system's support cells seems to play two opposing roles in protecting nerve cells from damage, an animal study by Johns Hopkins researchers suggests: Decreasing its activity seems to trigger support cells to gear up their protective powers, but increasing its activity appears to be key to actually use those powers to defend cells from harm.

Neural protein plays two opposing roles

A protein produced by the central nervous system’s support cells seems to play two opposing roles in protecting nerve cells from damage, an animal study by Johns Hopkins researchers suggests: Decreasing its activity seems to trigger support cells to gear up their protective powers, but increasing its activity appears to be key to actually use those powers to defend cells from harm.

New insight into immune-cell movement patterns

By pairing an intimate knowledge of immune-system function with a deep understanding of statistical physics, a cross-disciplinary team at the University of Pennsylvania has arrived at a surprising finding: T cells use a movement strategy to track down parasites that is similar to strategies that predators such as monkeys, sharks and blue-fin tuna use to hunt their prey.

New diagnostic approach for Lyme disease

George Mason University researchers can find out if a tick bite means Lyme disease well before the bite victim begins to show symptoms.

RUB researchers gain new insights into mechanisms of cardiovascular disease

Malformed desmin proteins aggregate with intact proteins of the same kind, thereby triggering skeletal and cardiac muscle diseases, the desminopathies. This was discovered by researchers from the RUB Heart and Diabetes Center NRW in Bad Oeynhausen led by PD Dr. Hendrik Milting in an interdisciplinary research project with colleagues from the universities in Karlsruhe, Würzburg and Bielefeld. They report in the Journal of Biological Chemistry.

Scientists discover how microglia detect the site of injury

Like emergency workers rushing to a disaster scene, cells called microglia speed to places where the brain has been injured, to contain the damage by 'eating up' any cellular debris and dead or dying neurons. Scientists at the European Molecular Biology Laboratory (EMBL) in Heidelberg, Germany, have now discovered exactly how microglia detect the site of injury, thanks to a relay of molecular signals.

Breakthrough in understanding the causes of unexplained male infertility

The diagnosis of male fertility is usually performed through the observation of the sperm in the microscope. However, a normal quality semen does not guarantee an adequate fertility. In fact, there is a considerable proportion of cases of unexplained infertility and data suggest that abnormal sperm function may have a genetic or molecular origin.

New MicroNav surgical technique provides greater safety and reduces pain

The revolutionary new MicroNav surgical technique, performed by Dr. Scott Hodges, gives greater safety, less pain, minimal cuts and faster recovery from spine surgery using high-tech 3D scanners and GPS-like instruments. These bold claims are backed by more than 600 surgeries with zero infections and zero revisions, a huge improvement over the high failure rate of "open" surgical techniques and questionable "laser" spine surgery.

Science journal’s NEWSFOCUS section describes recent advances in sequencing technology

Rapid DNA sequencing may soon become a routine part of each individual's medical record, providing enormous information previously sequestered in the human genome's 3 billion nucleotide bases. This week's NEWSFOCUS section of the journal Science describes recent advances in sequencing technology.

Special feature of Science journal highlights protein array technology

A special feature in this week's issue of the journal Science highlights protein array technology, touching on research conducted by Joshua LaBaer, director of the Biodesign Institute's Virginia G. Piper Center for Personalized Diagnostics.

New optical microscope sees individual blood cells as they flow inside the body

Blood tests convey vital medical information, but the sight of a needle often causes anxiety and results take time. A new device developed by a team of researchers in Israel, however, can reveal much the same information as traditional blood test in real-time, simply by shining a light through the skin.

Tiny filter could fight against tuberculosis

A tiny filter could have a big impact around the world in the fight against tuberculosis. Using the traditional microscope-based diagnosis method as a starting point, a University of Florida lung disease specialist and colleagues in Brazil have devised a way to detect more cases of the bacterial infection.

Linkam Scientific temperature controlled warm stages chosen for sperm motility in human fertility testing

Market leaders in temperature controlled microscopy, Linkam Scientific Instruments, have been chosen by an NHS Fertility clinic as suppliers of a controlled warm stage to perform routine semen analysis at body temperature.

New technique measures brain activity in large populations of nerve cells

Researchers have developed a new technique which allows them to measure brain activity in large populations of nerve cells at the resolution of individual cells. The technique, reported today in the journal Nature, has been developed in zebrafish to represent a simplified model of how brain regions work together to flexibly control behaviour.

Chemically altered proteins may be key to understanding memories

Having a fat head may not be a bad thing, according to new findings at The Johns Hopkins University. As reported in the February 9 issue of Neuron, researchers have made a significant discovery as to how adding fat molecules to proteins can influence the brain circuitry controlling cognitive function, including learning and memory.

UCLA creates crowd-sourced online gaming system to detect malaria

Online crowd-sourcing - in which a task is presented to the public, who respond, for free, with various solutions and suggestions - has been used to evaluate potential consumer products, develop software algorithms and solve vexing research-and-development challenges. But diagnosing infectious diseases?

JAM-A protein a far more powerful clot inhibitor: Study

Cut your toe, and platelets -- those disc-shaped cells circulating in your blood -- rush to the scene, clumping together to plug the leak. But when an unwanted clot forms in an artery, and an overaccumulation of platelets blocks blood flow, a heart attack or stroke occurs, too often with fatal results.
