Humans have taken spiders into space more than once to study the importance of gravity to their web-building. What originally began as a somewhat unsuccessful PR experiment for high school students has yielded the surprising insight that light plays a larger role in arachnid orientation than previously thought.
Exercise plays a key role in maintaining good physical and mental health throughout life. There is an increasing amount of scientific evidence that some of the immune system and metabolism benefits provided by sport are related to the thousands of millions of bacteria that colonize the digestive tract, from the mouth to the intestines, known as microbiota.
What causes the characteristic slowing of movement in patients with Parkinson's disease? Electrical oscillations of nerve cells deep inside the brain and the cortex are pathologically coupled with each other. Researchers know this from recordings taken from the brains of Parkinson's patients during surgery to fit a brain pacemaker.
They signal across tissues from the site of injury to the brain, sending a message to increase sleep and raise the chances for surviving the injury. The results have been published in the journal Current Biology.
Sleep is the best medicine, as the old saying goes. Indeed, studies showed that longer sleep leads to a better recovery. It is no surprise that our brains respond to an injury by extending our sleep. But how does that happen? How does the brain know about the injury? Is there some kind of long-range message sent to the brain from the wound?
Although most of the planet is covered by water, only a fraction of it is clean enough for humans to use. Therefore, it is important to recycle this resource whenever possible. Current purification techniques cannot adequately handle the very hot wastewater generated by some industries. But now, researchers reporting in ACS Applied Materials & Interfaces have embedded amine-enhanced nanodiamond particles into membranes to address this challenge.
Once used to prepare cuisine in only the finest restaurants, sous vide is now making its way into home chefs' kitchens. French for "under vacuum," the technique involves vacuum sealing food in a plastic pouch and then slowly cooking it in warm water. Now, researchers reporting in ACS' Journal of Agricultural and Food Chemistry have found that, compared with boiling or roasting, sous vide increases beef protein digestibility during simulated digestion.
Washington, DC, December 9, 2020 - Individuals diagnosed with autism spectrum disorder (ASD) face a lifelong challenge characterized by qualitative impairments in both communication and social interaction.
In recent years, the energy consumption in developed countries has been rather wasteful. Nearly two-thirds of the total energy is typically discarded into the environment as "waste heat," which ends up contributing to global warming. Finding a way to productively use this heat has been at the forefront of every material researcher's priority.
p>New research shows that conservation efforts in the Atlantic Ocean may be working for one of the most popular — and endangered — species that ends up in the global shark fin trade. Diego Cardeñosa — an FIU postdoctoral researcher in the Institute of E
FORT LAUDERDALE/DAVIE, Fla. - In a year like no other, it's certainly fitting that we had hurricane season that followed suit. It seemed every time we turned around, there was a tropical disturbance brewing that eventually became a named storm.
A study conducted on mice published in the journal Geroscience has identified the action mechanism of a promising compound against Alzheimer's disease, developed by the team of Medical Chemistry and Pharmacology at the University of Barcelona. The new drug belongs to a family of molecules that, when bound to imidazole I2 receptors, these cause a reduction in neuroinflammation and an improvement in cognition and other markers of the progression of this disease, the most prevalent among dementias.
The positively charged protons in atomic nuclei should actually repel each other, and yet even heavy nuclei with many protons and neutrons stick together. The so-called strong interaction is responsible for this. Prof. Laura Fabbietti and her research group at the Technical University of Munich (TUM) have now developed a method to precisely measure the strong interaction utilizing particle collisions in the ALICE experiment at CERN in Geneva.
New Rochelle, NY, December 8, 2020--Time to reach the target body temperature was a significant factor in achieving favorable neurological outcomes in patients with witnessed out-of-hospital cardiac arrest. Significantly more favorable neurological outcomes occurred if the time to target temperature management was Therapeutic Hypothermia and Temperature Management. Click here to read the article now.
Certain sections of aero gas-turbine engines, which are widely used in aircrafts, regularly reach temperatures above 1,200 °C. Needless to say, any materials used in such harsh environments must be durable and up to the task. Ceramic matrix composites made of silicon carbide (SiC) have recently garnered interest as promising candidates for gas-turbine engines.
"Happy families are all alike; each unhappy family is unhappy in its own way." So goes the first line of Leo Tolstoy's "Anna Karenina." Little did the Russian novelist know his famous opening line would one day be used to describe microbial communities, their health and their relationships to their hosts.
