A clinical trial in people with the new coronavirus is testing a drug that may halt an overactive immune response before it ramps up.

Engineers have achieved the broadest recorded spectral span in a microcomb.

Using SLAC's high-speed 'electron camera,' scientists simultaneously captured the movements of electrons and nuclei in a light-excited molecule. This marks the first time this has been done with ultrafast electron diffraction, which scatters a powerful beam of electrons off materials to pick up tiny molecular motions.

Towable sensor free-falls to measure vertical slices of ocean conditions.

High-intensity fires can destroy marshy peatlands and cause them to emit huge amounts of their stored carbon into the atmosphere as greenhouse gases, but a new study finds low-severity fires spark the opposite outcome. By creating a decay-inhibiting crust on clumps of moist soil particles within the peatland, the smaller surface fires help protect the stored carbon and enhance peatlands' long-term...

The gene-editing technology CRISPR has been used for a variety of agricultural and public health purposes -- from growing disease-resistant crops to, more recently, a diagnostic test for the virus that causes COVID-19. Now a study involving fish that look nearly identical to the endangered Delta smelt finds that CRISPR can be a conservation and resource management tool, as well. The researchers...

Researchers have developed a deep-learning model that maps fuel moisture levels in fine detail across 12 western states, opening a door for better fire predictions.

Researchers have discovered a way to monitor the performance of 3D printed parts, which tend to have imperfections that affect performance in ways traditionally-machined parts do not.

Nearly half of parents of children under age 18 say their stress levels related to the coronavirus pandemic are high, with managing their kids' online learning a significant source of stress for many, according to a new survey by the American Psychological Association.

Research demonstrates that the characteristic zig-zag pattern on a viper's back performs opposing functions during a predation event. At first, the zig-zag pattern helps the snake remain undetected. But upon exposure, it provides a conspicuous warning of the snake's dangerous defense. Most importantly the zig-zag can also produce an illusionary effect that may hide the snake's movement as it...

The carbon-hydrogen bond -- 2/3 of all bonds in hydrocarbons -- has defied chemists' attempts to open it up and add new chemical groups. A team has now cracked the strongest of C-H bonds, those on a molecule's terminal carbon. The reaction catalyst is an iridium atom to break the bond and a methyl group to add a boron compound. Boron is easily exchanged for other groups, allowing additions to...

Regions of Italy with higher family fragmentation and a high number of residential nursing homes experienced the highest rate of COVID-19 infections in people over age 80, according to a new study.

COVID-19 infection may cause subacute thyroiditis, according to a new case study.

A cost-effective method to stabilise perovskite solar cells could soon see them become commercially viable.

Scientists have identified specific compounds from the Brazilian peppertree -- a weedy, invasive shrub in Florida -- that reduce the virulence of antibiotic-resistant staph bacteria. This research demonstrates that triterpenoid acids in the red berries of the plant ''disarm'' dangerous staph bacteria by blocking its ability to produce toxins.

Researchers have used state-of-the-art atomic clocks, advanced light detectors, and a measurement tool called a frequency comb to boost the stability of microwave signals 100-fold. This marks a giant step toward better electronics to enable more accurate time dissemination, improved navigation, more reliable communications and higher-resolution imaging for radar and astronomy.

New research is one of the first comprehensive characterizations of poorly formed memories and may offer a framework to explore different therapeutic approaches to fear, memory and anxiety disorders. It may also have implications for accuracy of some witness testimony.

Tropical forests face an uncertain future under climate change, but new research suggests they can continue to store large amounts of carbon in a warmer world, if countries limit greenhouse gas emissions.

The rate of strokes in COVID-19 patients appears relatively low, but a higher proportion of those strokes are presenting in younger people and are often more severe compared to strokes in people who do not have the novel coronavirus, while globally rates for stroke hospitalizations and treatments are significantly lower than for the first part of 2019, according to new research.

Researchers have developed a membrane that can be attached to a regular N95 mask and replaced when needed. The filter has a smaller pore size than normal N95 masks, potentially blocking more virus particles.

Red blood cells sometimes rupture when blood is sent through faulty equipment, such as a dialysis machine. This is called hemolysis. Hemolysis also can occur during blood work when blood is drawn too quickly through a needle, leading to defective laboratory samples. Researchers have now developed a method to monitor blood damage in real-time.

Researchers have revealed their new biodegradable motion sensor -- paving the way for implanted nanotechnology that could help future sports professionals better monitor their movements to aid rapid improvements, or help caregivers remotely monitor people living with dementia.

Researchers found that adding six grams of spices to a meal high in fat and carbohydrates resulted in lower inflammation markers hours later.

A new study has revealed why some corals exhibit a dazzling colorful display, instead of turning white, when they suffer 'coral bleaching' -- a condition which can devastate reefs and is caused by ocean warming. The scientists behind the research think this phenomenon is a sign that corals are fighting to survive.
