You would not ask a firefighter to perform open-heart surgery: Understanding 'collective intelligence'
The concept of 'collective intelligence' is simple -- it asserts that if a team performs well on one task, it will repeat that success on other projects, regardless of the scope or focus of the work. While it sounds good in theory, it doesn't work that way in reality, according to a researcher.

Flexible 'skin' can help robots, prosthetics perform everyday tasks by sensing shear force
Engineers have developed a flexible sensor 'skin' that can be stretched over any part of a robot's body or prosthetic to accurately convey information about shear forces and vibration, which are critical to tasks ranging from cooking an egg to dismantling a bomb.

Cancer: New compound targets energy generation, thereby killing metastatic cells
Researchers have identified an enzyme that supports the survival and dissemination of metastatic cells, and developed a synthetic compound that targets the enzyme and kills the metastatic cells in mice with cancer.

HIV infection, even with antiretroviral therapy, appears to damage a growing child's brain
One of the largest and best-documented trials of children receiving early antiretroviral therapy -- the CHER clinical trial in South Africa -- finds ongoing white matter damage in HIV-positive children at the age of 7 years. The study aims to contribute to a better understanding of brain development in HIV-infected and exposed children, as well as the impact of long-term antiretroviral treatment.

Resolving traffic jams in human ALS motor neurons
A team of researchers used stem cell technology to generate motor neurons from ALS patients carrying mutations in FUS. They found disturbed axonal transport in these motor neurons, but also identified genetic and pharmacological strategies that mitigate this defect.

On-and-off fasting helps fight obesity, study finds
Up to sixteen weeks of intermittent fasting without otherwise having to count calories helps fight obesity and other metabolic disorders. Such fasting already shows benefits after only six weeks, according to a new study.
