Human error, not human biology, largely accounts for the apparent decline of mortality among the very old, according to a new report. The result casts doubt on the hypothesis that human longevity can be greatly extended ...

Droplet microfluidics has revolutionized single-cell RNA sequencing, offering a low-cost, high-throughput method for single-cell genomics. However, this method has been limited in its ability to capture complete RNA tran...

Since 2012, the number of cases of leprosy in Morocco has declined by more than 16 percent per year. That change can be attributed to the implementation, beginning in 2012, of single dose rifampicin as a preventive to sp...

Neuroscientists have discovered how neurons in the digestive tract of the worm C. elegans signal the brain to slow down when it encounters an area of plentiful food.

Researchers have revealed a novel mechanism for stem cell number control.

Current HIV treatments need to be taken for life by those infected as antiretroviral therapy is unable to eliminate viral reservoirs lurking in immune cells. Scientists have identified the characteristics of CD4 T lympho...

About 3.4 million Americans, or 1.2 percent of the population, have active epilepsy. Although the majority respond to medication, between 20 and 40 percent of patients with epilepsy continue to have seizures even after t...

Researchers have successfully visualized the tumor microenvironment of human breast tissue shortly after it was surgically removed from a patient in the operating room. The researchers achieved this using a new portable ...

A new study shows that urine drug testing can be a useful tool to treat patients with opioid use disorder in a primary care setting.

Himalayan marmots can survive at altitudes up to 5,000 meters in the Himalayan regions of India, Nepal, and Pakistan and on the Qinghai-Tibetan Plateau of China, where many of them face extreme cold, little oxygen, and f...

An interdisciplinary team has created a drug delivery system that could radically expand cancer treatment options.

A new study has found that eyeball and eyelid movement, or oculomotor function, which is used to detect symptomless brain injury, can be impaired by mild, repetitive head impacts in football players. But the function may...

Magnetic recording is the primary technology underpinning today's large-scale data storage. Now, companies are racing to develop new hard disk devices (HDDs) capable of recording densities greater than 1 terabit per squa...

It isn't unreasonable to think of drones as pesky technological nuisances. Our modern digital ecosystem regularly infringes on traditional notions of privacy and bombards our limited attention spans with stimuli. A swarm...

Researchers have demonstrated a new technique that can store more optical data in a smaller space than was previously possible on-chip. This technique improves upon the phase-change optical memory cell, which uses light ...

Researchers in Italy have demonstrated the feasibility of quantum communications between high-orbiting global navigation satellites and a ground station, with an exchange at the single photon level over a distance of 20,...

There are lots of interconnected tipping points linking the climate and environment, so drastic changes to the planet will have many unexpected consequences

Researchers have identified neurons in the guts of C. elegans that detect when bacteria are ingested and release a neurotransmitter that signals the brain to halt locomotion.

Fill in the blanks for some physics fun. 'Tis the season for friends, family and funny physics fill-ins. Here at Symmetry, we've taken a page from Mad Libs, those short stories designed to trick you into learning parts o...

A study in mice shows that certain gut bacteria may exacerbate lupus, but eating starch can halt their growth, hinting at a possible treatment

Our first glimpses into the physics that exist near the center of a black hole are being made possible using "loop quantum gravity"--a theory that uses quantum mechanics to extend gravitational physics beyond Einstein's ...

NASA and the Sunnyvale, California-based AOSense, Inc., have successfully built and demonstrated a prototype quantum sensor capable of obtaining highly sensitive and accurate gravity measurements--a stepping stone toward...
