PITTSBURGH -- Chalk up one more task a smartphone app may do better than you: figuring out your privacy settings.
A field study suggests a personalized privacy assistant app being developed at Carnegie Mellon University can simplify the chore of setting permissions for your smartphone apps. That's a task that requires well over a hundred decisions, an unmanageable number for the typical user.
The privacy assistant can learn the user's preferences and quickly recommend the most appropriate settings, such as with which app to share the user's location, or contact list.

Eph receptors and their partner proteins, the ephrins, are vital for intercellular communication. In the developing brain, they guide young neurons to the right partner cells by repulsion. They also play important roles in cell migration, regeneration, neurodegenerative diseases and the development of cancer. Until recently, scientists assumed that ephrin/Eph signal transmission could only occur through direct cell-cell contact.

LA JOLLA--A small stretch of ribonucleic acid called microRNA could make the difference between a healthy adult brain and one that's prone to disorders including schizophrenia.
Scientists at the Salk Institute discovered that miR-19 guides the placement of new neurons in the adult brain, and the molecule is disrupted in cells from patients with schizophrenia. The findings, published in the journal Neuron on July 6, 2016, pave the way toward a better understanding of how the adult brain controls the growth of new neurons and how it can go wrong.

By activating particular neurons, we may be able to influence alcohol drinking behavior, according to new findings published by researchers at the Texas A&M Health Science Center College of Medicine in the journal Biological Psychiatry.
The group's prior research showed that alcohol consumption alters the physical structure and function of neurons, called medium spiny neurons, in the dorsomedial striatum. Essentially, they found that activation of one type of neuron, called D1, determines whether one drink leads to two. Now, they've discovered the ones that tell us to stop.

Driving is possibly one of the most complex procedures humans engage in on a regular basis. Operating a motor vehicle involves a wide range of cognitive processes that require the ability to judge distances, manage multiple stimuli simultaneously, react quickly in an emergency, maintain attention for long periods of time, and correctly interpret traffic signs and signals.

BINGHAMTON, NY - Wearable devices can give away your passwords, according to new research.
In the paper "Friend or Foe?: Your Wearable Devices Reveal Your Personal PIN" scientists from Binghamton University and the Stevens Institute of Technology combined data from embedded sensors in wearable technologies, such as smartwatches and fitness trackers, along with a computer algorithm to crack private PINs and passwords with 80-percent accuracy on the first try and more than 90-percent accuracy after three tries.

Scientists at the University of Exeter have developed a pioneering new technique that could revolutionise the surgical treatment of epilepsy.
The team of scientists, led by Dr Marc Goodfellow and Professor John Terry, have developed the ground-breaking new method that can identify the specific regions of the brain that trigger seizures in people with epilepsy.

In a study appearing in the July 5 issue of JAMA, Blayne Welk, M.D., M.Sc., of Western University, London, Canada, and colleagues conducted a study to assess the association between gadolinium exposure and parkinsonism, a degenerative disorder of the central nervous system characterized by tremor and impaired muscular coordination.
