Keeping Kids Safe In the "Internet of Things" Era
Children need protection when using programmable Internet computing devices – and Lancaster University scientists have drawn up new guidelines to help designers build in safeguards.

On the Origin of Astrocytes
During fetal brain development, both neurons and astrocytes are generated from neural stem cells. One of the characteristics of this developmental process is that neural stem cells first generate neurons and, after that, start generating astrocytes. The "switch" to change the fate of neural stem cells from neurons to astrocytes has remained largely unidentified. Until now.

Protein Stability Influences Stem Cell State
Protein stabilization has been implicated as a major factor in maintaining control of the stem cell state.

Alcohol's Impact On Our Sense of Control Suggests We Need to Rethink Legal Limits
New research by neuroscientists from the University of Sussex shows that drinking only one pint of beer or large glass of wine is enough to significantly compromise a person's sense of agency.

Mouse Brains Sync Up When Socializing
UCLA researchers have published a Cell study showing that the brains of pairs of animals synchronize during social situations. The synchronized activity not only arose during various types of social behavior, but also the level of synchronization actually predicted how much the animals would interact.

Autism Gene Linked to Changes Occurring Around Symptom Onset
Unlike other gene mutations linked to autism, which are thought to alter brain development before birth, the newly identified changes in brain signaling may occur closer to the onset of autism symptoms in the first years of life, raising hope that a future therapy could be developed.

A Drug Target for Chemically Induced Parkinson's Disease
The synthetic opioid, MPTP, induces the onset of a form of Parkinson's disease. In a new study, researchers found that an enzyme in the body can metabolize compounds formed in the brain from alkaloids present in certain foods and tobacco into MPTP-like chemicals, triggering a neurodegenerative condition in mice.

Kitchen Sponges Host Bacteria-fighting Microbes
Kitchen sponges have been found to host viruses that infect bacteria, called bacteriophages. As the threat of antibiotic resistance increases, bacteriophages, or phages for short, may prove useful in fighting bacteria that cannot be killed by antibiotics alone,

New Way to Deliver Drugs Through the Skin Using “Nanoemulsion” Gels
MIT chemical engineers have devised a new way to create very tiny droplets of one liquid suspended within another liquid, known as nanoemulsions. They also found a way to easily convert the liquid nanoemulsions to a gel when they reach body temperature, which could be useful for developing materials that can deliver medication when rubbed on the skin or injected into the body.
