Mind-controlled device helps stroke patients retrain brains to move paralyzed hands
Stroke patients who learned to use their minds to open and close a plastic brace fitted over their paralyzed hands gained some ability to control their own hands when they were not wearing the brace, according to a new study. The participants, all of whom had moderate to severe paralysis, showed significant improvement in grasping objects.

Losing sleep over climate change
A new study of US data suggests a sleep-deprived planet by century's end. Researchers show that unusually warm nights can harm human sleep and that the poor and elderly are most affected. Rising temperatures will make sleep loss more severe.

Chemical array draws out malignant cells to guide individualized cancer treatment
Melanoma is a particularly difficult cancer to treat once it has metastasized, spreading throughout the body. Researchers are using chemistry to find the deadly, elusive malignant cells within a melanoma tumor that hold the potential to spread. Once found, the stemlike metastatic cells can be cultured and screened for their response to a variety of anti-cancer drugs, providing the patient with an individualized treatment plan based on their own cells.

'Tiny clocks' crystallize understanding of meteorite crashes
Scientists are using new imaging techniques to measure the atomic nanostructure of ancient crystal fragments at meteorite impact sites. The end goal? To understand when impacts ended and life began.

Bioelectricity new weapon to fight dangerous infection
Changing natural electrical signaling in non-neural cells improves innate immune response to bacterial infections and injury. Tadpoles that received therapeutics, including those used in humans for other purposes, which depolarized their cells had higher survival rates when infected with E. coli than controls. The research has applications for treatment of emerging diseases and traumatic injury in humans.

New cellular target may put the brakes on cancer's ability to spread
Researchers have discovered a biochemical signaling process that causes densely packed cancer cells to break away from a tumor and spread the disease elsewhere in the body.

Century-old drug as potential new approach to autism
In a small, randomized Phase I/II clinical trial (SAT1), researchers say a 100-year-old drug called suramin, originally developed to treat African sleeping sickness, was safely administered to children with autism spectrum disorder (ASD), who subsequently displayed measurable, but transient, improvement in core symptoms of autism.
