A lot of problems, associated with the mixing of the liquid in the microchannels, could be solved via proper organization of the inhomogeneous slip on the walls of these channels, according to a joint group of Russian and German scientists lead by Olga Vinogradova, professor at the M.V. Lomonosov Moscow State University. 

Scientists are beginning to unwrap the biology behind why some people are more prone to major depression and other psychiatric disorders than others when experiencing stressful life events.

The researchers found that cellular activity in response to stress hormone receptor activation differs from individual to individual.

The study, led by Janine Arloth, Ryan Bogdan, and Elisabeth Binder at the Max Planck Institute of Psychiatry in Germany, also shows that the genetic variations underlying this difference in stress response correlate with dysfunction in the amygdala, a brain region that is an important part of the stress hormone response.

 Researchers have used satellite data to detect deposits of glass within impact craters on Mars. Though formed in the searing heat of a violent impact, the glasses just might provide a delicate window into the possibility of past life on the Red Planet.

Over the last few years, several research groups have shown that, here on Earth, ancient biosignatures can be preserved in impact glass. One of those studies, led by Brown geologist Peter Schultz and published last year, found organic molecules and even plant matter entombed in glass formed by an impact that occurred millions of years ago in Argentina. Schultz suggested that similar processes might preserve signs of life on Mars, if indeed they were present at the time of an impact.

Amateur cook-offs like the hugely popular MasterChef series now in its seventh season in Australia have been part of our TV diet for almost two decades.

These shows celebrate the remarkable lengths we humans will go to to whet the appetite, stimulate the senses, fire our neural reward systems and sustain the body.

Yet, few of us pause to reflect on the hugely important role diet plays in the ecology and evolutionary history of all species, including our own.

NASA has released data showing how temperature and rainfall patterns worldwide may change through the year 2100 because of growing concentrations of greenhouse gases in Earth's atmosphere.

The dataset shows projected changes worldwide on a regional level in response to different scenarios of increasing carbon dioxide simulated by 21 climate models. The high-resolution data, which can be viewed on a daily timescale at the scale of individual cities and towns, will help scientists and planners conduct climate risk assessments to better understand local and global effects of hazards, such as severe drought, floods, heat waves and losses in agriculture productivity. 

Welcome to a new way to manipulate matter. 

Mixing computers and water typically is usually a bad idea but bioengineers at Stanford have built a synchronous computer that operates using the physics of moving water droplets. They used droplet fluid dynamics to demonstrate a synchronous, universal droplet logic and control.

Because of its universal nature, the droplet computer can perform any operation that a conventional electronic computer can crunch, although still at significantly slower rates in this early stage. 

The crucial clock 

Researchers have found that the severity of ranavirosis, a devastating disease that kills thousands of frogs each year, increases in the presence of exotic fish. The use of garden chemicals was also associated with increased severity of the disease. 

Modified "good" cholesterol (HDL) and the activation of specific genes are causes of damage to the vascular system in chronic renal disease. A new project specifically examined the effect of cyanate, a decomposition product of urea, on the functioning of the vascular system.
The issue is important because the average age of the general population is increasing and with it the number of patients with chronic renal disease. Their mortality increases sharply in particular as a result of secondary cardiovascular disease. To date, however, little is known about how these sequelae occur.

As the founder of Fitness Reloaded, a health and fitness company the most common questions I’ve received through the years is about food. Should we eat this or that? Vegetarian or Paleo? GMOs safe or not? And what about superfoods?

I always dodged the eating questions and preferred to talk about fitness instead. The reason was that I felt that since the “experts”, doctors, dieticians, etc, couldn’t agree on what we should really be eating, then how would I expect that I would give a good answer?

Among the many things that CMS and ATLAS physicists are looking forward to checking up, using the data that the LHC is starting to deliver from 13 TeV proton-proton collisions, one is the WH resonance signal that CMS found in a recent analysis. Mind you, "signal" here is a misnomer: what was seen was most probably a insignificant fluctuation of the background; yet we must keep our mind open to interpretation changes.

The search I am talking about is one CMS did for boosted Higgs bosons recoiling against boosted W bosons, in a "back-to-back" topology (paper is here).
