In a new study, Brown University neuroscientists looked cell-by-cell at the brain circuitry that tadpoles, and possibly other animals, use to avoid collisions. The study produced a model of how individual inhibitory and excitatory neurons can work together to control a simple behavior.

PROVIDENCE, R.I. [Brown University] — A neuroscience study provides new insight into the primal brain circuits involved in collision avoidance, and perhaps a more general model of how neurons can participate in networks to process information and act on it. (more…)

Diabolical duo: Known breast cancer gene needs a partner to initiate and spread tumors

A study led by Princeton University researchers has revealed that the gene Metadherin — which is implicated in promoting the spread of breast cancer tumors — only stimulates tumor growth when the protein made by the gene interacts with a second protein known as SND1. (more…)

UCLA-led study also finds that the approach may shorten surgeries, which could reduce risk of complications

Roughly 50,000 Americans are diagnosed with kidney cancer each year. Most of them have small tumors that doctors discover while screening for other health problems. (more…)

How to rejuvenate ageing immune cells

Researchers from UCL have demonstrated how an interplay between nutrition, metabolism and immunity is involved in the process of ageing.

The two new studies, supported by the Biotechnology and Biological Sciences Research Council (BBSRC), could help to enhance our immunity to disease through dietary intervention and help make existing immune system therapies more effective. As we age our immune systems decline. Older people suffer from increased incidence and severity of both infections and cancer. In addition, vaccination becomes less efficient with age. (more…)

UCLA has been tapped by the Defense Advanced Research Projects Agency to spearhead an innovative project aimed at developing a wireless, implantable brain device that could help restore lost memory function in individuals who have suffered debilitating brain injuries and other disorders. (more…)

All HIV not created equal: Scientists believe they can identify which viruses cause infection

ANN ARBOR — HIV-infected people carry many different HIV viruses and all have distinct personalities—some much more vengeful and infectious than others.

Yet, despite the breadth of infectivity, roughly 76 percent of HIV infections arise from a single virus. Now, scientists believe they can identify the culprit with very specific measurements of the quantities of a key protein in the HIV virus. (more…)

New line of pigs do not reject transplants, will allow for future research on stem cell therapies

COLUMBIA, Mo. – One of the biggest challenges for medical researchers studying the effectiveness of stem cell therapies is that transplants or grafts of cells are often rejected by the hosts. This rejection can render experiments useless, making research into potentially life-saving treatments a long and difficult process. Now, researchers at the University of Missouri have shown that a new line of genetically modified pigs will host transplanted cells without the risk of rejection. (more…)
