Imagine someone hands you a smoothie and asks you to identify everything that went into it.
You might be able to discern a hint of strawberry or the tang of yogurt. But overall it tastes like a blend of indiscernible ingredients.
Now imagine that the smoothie is made of 20,000 ground-up cells from, say, the brain.
Researchers have observed a sudden increase of ice loss in a previously stable region of Antarctica. Using measurements of the elevation of the Antarctic ice sheet made by a suite of satellites, the researchers found that the Southern Antarctic Peninsula showed no signs of change up to 2009. Around 2009, multiple glaciers along a vast coastal expanse, measuring some 750 kilometers in length, suddenly started to shed ice into the ocean at a nearly constant rate of 60 cubic kilometers, or about 55 trillion liters of water, each year.
An extract from the thunder god vine, long used in traditional Chinese medicine, reduces food intake and causes up to a 45% decrease in body weight in obese mice. The weight-loss compound, called Celastrol, produces its potent effects by enhancing the action of an appetite-suppressing hormone called leptin. The findings are an early indicator that Celastrol could be developed into a drug for the treatment of obesity.
A drug that promotes weight loss in obese mice by causing them to burn off excess calories is reported in a study published in Nature Communications this week. The drug causes the mice to generate more brown and beige fat, which are specialised tissues that burn lipid molecules to generate heat.
Malaria is a cruel and disabling disease that targets victims of all ages. Even now, it is estimated to kill one child every minute. Recent progress in halting the spread of the disease has hinged on the use of insecticide-treated bed nets and spraying programmes that target the insect that spreads the disease, the African malaria mosquito (Anopheles gambiae).
Phase 2b clinical trial results that demonstrated statistically significant and clinically meaningful improvement in IBS-C symptoms for tenapanor-treated patients compared to patients receiving placebo.
As previously reported, at the 50 mg dose of tenapanor, the study met its primary efficacy endpoint of an increase in the complete spontaneous bowel movement (CSBM) responder rate. Most secondary endpoints, including abdominal pain and other abdominal and IBS-C symptoms, demonstrated clinically meaningful improvements.
Sulimov dogs are specially bred for Aeroflot's canine service through crossing the Arctic Herding Laika and the Subtropical Jackal. The Sulimov dog is as hardy, unpretentious, loyal and smart as its Arctic ancestor. The new breed took its good sense of smell from the subtropical relative.
These specially-trained dogs live in Aeroflot's Aviation Safety Department Canine Unit and are an integral part of aviation safety.
Enrollment of the first patients into STEADFAST (Single Trial Evaluating Alzheimer's Disease Following Addition to Symptomatic Therapy), vTv's Phase 3 placebo controlled trial of azeliragon, an oral antagonist of the Receptor for Advanced Glycation Endproducts (RAGE) for treatment of mild Alzheimer's disease has begun. Phase 3 begins following a Phase 2 trial that demonstrated positive results in slowing cognitive decline with 5 mg/day of azeliragon in patients with mild to moderate Alzheimer's Disease.
Human error is estimated to cause more than 90% of traffic accidents, a percentage that might be drastically reduced by the implementation of self-driving cars featuring smart systems that control most aspects of driving. Although the potential benefits of self-driving cars have been widely touted, their success on the roadways of the near future is largely reliant on whether or not drivers are willing to trust these smart systems enough to hand over the wheel.
A class of FDA-approved cancer drugs may be able to prevent problems with brain cell development associated with disorders including Down syndrome and Fragile X syndrome, researchers at the University of Michigan Life Sciences Institute have found.
Researchers have held tremendous interest in liquid metal electronics for many years, but a significant and unfortunate drawback slowing the advance of such devices is that they tend to require external pumps that can't be easily integrated into electronic systems.
So a team of North Carolina State University (NCSU) researchers set out to create a reconfigurable liquid metal antenna controlled by voltage only, which they describe in the Journal of Applied Physics, from AIP Publishing.
The FDA has granted a Clinical Laboratory Improvement Amendments (CLIA) waiver for the cobas Liat PCR System and the cobas Strep A test, the first FDA-cleared device to offer polymerase chain reaction (PCR) technology at the point of care, including doctor’s offices and pharmacies.
Nuclear power is likely the least well-understood energy source in the United States. Just 99 nuclear power plants spread over 30 states provide one-fifth of America’s electricity. These plants have provided reliable, affordable and clean energy for decades. They also carry risk - to the public, to the environment and to the financial solvency of utilities.
The case for expanding nuclear energy is based on myths about its status, greenhouse gas emissions, proliferation, accidents, wastes and economics. Let’s take each in turn.

University of Utah engineers have taken a step forward in creating the next generation of computers and mobile devices capable of speeds millions of times faster than current machines.
