    In your dreams! Researchers achieve two-way communication with dreaming people

    In your dreams! Researchers achieve two-way communication with dreaming people

    By monitoring electrical signals from the sleeping participants' brain and eyes, researchers at Northwestern University, along with scientists in France, Germany and the Netherlands, have independently demonstrated two-way communication with people as they are lucidly dreaming during REM (rapid eye movement) sleep. The breakthrough challenges current paradigms of human consciousness.

    ‘Iron Man’ bacteria could become economic and environmental heroes

    ‘Iron Man’ bacteria could become economic and environmental heroes

    Michigan State University researchers have shown that soil bacteria known as Geobacter are effective cobalt "miners," extracting the rare, toxic metal from rust without letting it penetrate their cells and kill them. Geobacter could form the basis of new biotechnology to reclaim and recycle cobalt from lithium-ion batteries, reducing the nation's dependence on foreign cobalt mines.

    Not so fast! New model analyzes how viruses escape the immune system

    Not so fast! New model analyzes how viruses escape the immune system

    MIT researchers devised a new way to computationally look at viral escape, based on models that were originally developed to analyze language. Their model can predict which sections of viral surface proteins are more likely to mutate in a way that enables viral escape. It can also identify sections that are less likely to mutate, making them good targets for new vaccines, possibly even one for cancer.

    Desalination breakthrough could lead to cheaper water filtration

    Desalination breakthrough could lead to cheaper water filtration

    Producing clean water at a lower cost could be on the horizon after researchers from The University of Texas at Austin and Penn State solved a complex problem that has baffled scientists for decades. In partnership with DuPont Water Solutions, the researchers determined that desalination membranes are inconsistent in density and mass distribution, and the inconsistency can hold back their performance.

    Tiny wireless device might help combat obesity

    Tiny wireless device might help combat obesity

    Texas A&M University researchers have developed a medical device that might help with weight loss while requiring a simpler operative procedure for implantation. The scientists say their centimeter-sized device provides the feeling of fullness by stimulating the endings of the vagus nerve with light. Unlike other devices that require a power cord, their device is wireless and can be controlled externally from a remote radio frequency source.

    Stimulating research could be moving for people with spinal cord injuries

    Stimulating research could be moving for people with spinal cord injuries

    Using physical therapy combined with a noninvasive method of stimulating nerve cells in the spinal cord, University of Washington researchers helped six Seattle area participants regain some hand and arm mobility. That increased mobility lasted at least three to six months after treatment had ended.
