Snorkeling gear, animal noses inspire better personal protective equipment

In March, Stanford University bioengineer Manu Prakash flew from France to his home in California and spent two weeks in personal quarantine. After being holed up in the room where he stores his snorkeling and scuba equipment, Prakash emerged with an idea for addressing two of the pandemic's most pressing challenges.

Researchers record largest aggregation of fishes in abyssal deep sea

The largest aggregation of fishes ever recorded in the abyssal deep sea was discovered by a team of oceanographers from the University of Hawai'i at Mānoa (UH, U.S.), Monterey Bay Aquarium Research Institute (MBARI, U.S.) and the National Oceanography Centre (NOC, UK). Their findings were published recently in Deep-Sea Research.

Flow physics could help forecasters predict extreme events

About 1,000 tornadoes strike the United States each year, causing billions of dollars in damage and killing about 60 people on average. Tracking data show that they're becoming increasingly common in the southeast, and less frequent in "Tornado Alley," which stretches across the Great Plains. Scientists lack a clear understanding of how tornadoes form, but a more urgent challenge is to develop more accurate prediction and warning systems. It requires a fine balance: Without warnings, people can't shelter, but if they experience too many false alarms, they'll become inured.

Early, late stages of degenerative diseases are distinct, study shows

Rice University biochemists Michael Stern and James McNew have studied how neurodegeneration kills cells. They've conducted countless experiments over more than a decade, and they've summarized all they've learned in a simple diagram they hope may change how doctors perceive and treat degenerative diseases as varied as Alzheimer's, Parkinson's and muscle atrophy.

Unique Schwann cells: The eyes have it

The insulation around nerve cell components in our corneas have unique properties, and little is known about them.

World's smallest atom-memory unit created

Faster, smaller, smarter and more energy-efficient chips for everything from consumer electronics to big data to brain-inspired computing could soon be on the way after engineers at The University of Texas at Austin created the smallest memory device yet.

Nature's toolkit for killing viruses and bacteria

They burst out of toilet bubbles, swim across drinking water, spread through coughs. Tiny infectious microbes—from the virus that causes COVID-19 to waterborne bacteria—kill millions of people around the world each year. Now engineers are studying how zinc oxide surfaces and natural hydrodynamic churning have the power to kill pathogens first.

BICRA gene provides answers to patients, doctors and scientists

Physicians and scientists are constantly on the lookout for new disease genes that can help them understand why patients have undiagnosed medical problems. Often the first clues come from genetic testing that reveals a change or mutation in a gene that they see in a child but not their parents. This is exactly what led to a new study published today in the American Journal of Human Genetics.

How to protect healthcare workers from COVID-19

The rapid spread of COVID-19 overwhelmed hospitals that were unable to contend with the increasing number of patients, many requiring ventilators and other critical care.

The secret origins of China's 40-year plan to end carbon emissions

The biggest emitter of planet-warming pollution managed to take almost the whole world by surprise. In a September speech to the United Nations, Chinese President Xi Jinping put a 2060 end date on his country's contribution to global warming. No other nation can do more to keep warming below the 1.5C threshold set in the Paris Agreement. Yet diplomats, climate activists and even policy experts inside China for the most part had not anticipated this pivotal turnabout.

Previewed Reality: A system that allows users to predict future changes in their environment

When robots and humans interact in a shared environment, it is important for them to move in ways that prevent collisions or accidents. To reduce the risk of collisions, roboticists have developed numerous of techniques that monitor an environment, predict the future actions of humans moving in it, identify safe trajectories for a robot and control its movements accordingly.

Vegans, vegetarians and pescetarians may be at higher risk of bone fractures

Compared with people who ate meat, vegans with lower calcium and protein intakes on average, had a 43% higher risk of fractures anywhere in the body (total fractures), as well as higher risks of site-specific fractures of the hips, legs and vertebrae, according to a study published in the open access journal BMC Medicine. Vegetarians and people who ate fish but not meat had a higher risk of hip fractures, compared to people who ate meat. However, the risk of fractures was partly reduced once body mass index (BMI), dietary calcium and dietary protein intake were taken into account.
