Light-activated molecular machines get cells 'talking'

One of the main ways cells "talk" to each other to coordinate essential biological activities such as muscle contraction, hormone release, neuronal firing, digestion and immune activation is through calcium signaling.

Female scent found to accelerate growth in juvenile male mice

Exposing female house mice (Mus musculus) to the scent of male urine is known to accelerate their sexual development in what scientists call the Vandenbergh effect. A study recently published in Scientific Reports led by ...

MYO armband to muscle into computer control (w/ video)

(Phys.org) —"Wave goodbye to camera-based gesture control." That is the confident directive coming from a one-year-old Waterloo, Ontario, startup called Thalmic Labs. The company is prepared to ship its next batch of wearable-computing ...

A novel system for slip prevention in unmanned rovers

Given the hostile conditions of extraterrestrial environments, unmanned rovers play a critical role in the exploration of planets and moons. NASA's Mars and lunar exploration rovers have significantly contributed to our understanding ...

New Year's science in space for a healthier life

Another year passes, and our muscles, bones, eyes and ears deteriorate as we age—even more so in space. Reactions in ESA astronaut Matthias Maurer's body after barely two months on the International Space Station are giving ...

A light-activated remote control for cells

What if doctors had a remote control that they could use to steer a patient's own cells to a wound to speed up the healing process? Although such a device is still far from reality, researchers reporting in the ACS journal ...
