Toward the right side of the periodic table below oxygen, are the chalcogens, or "ore-forming" elements. The chalcogens that occur naturally, including sulfur, selenium and tellurium, are all somehow involved in biological processes. Molecules containing sulfur, like the
New research led by scientists at UC San Diego's Scripps Institution of Oceanography is shining a spotlight on one of the ocean's most overlooked habitats: seagrass. Led by Scripps Oceanography Ph.D. candidate Rilee Sanders, the study documented the first successful restoration
Droughts are becoming both more frequent and more intense in many parts of the world. Savannas, which cover nearly 20% of Earth's land surface and play a key role in carbon, water and energy cycles, can therefore be severely affected when an exceptionally dry period strikes.
Many people use drugs, including paracetamol, on a regular basis to treat headaches. But only part of each drug is taken into the bloodstream, while the rest is released into the wastewater through our urine when we go to the toilet.
A team of researchers from Tel Aviv University, in collaboration with colleagues from Japan, has taken an important step toward the next generation of electronics. The scientists achieved highly precise control of the internal structure of graphene—an exceptionally thin and

A 600-year-old grape seed discovered in the toilets of a medieval French hospital is genetically identical to the grapes still being used to make pinot noir wine, scientists said Tuesday.
Jack Welch, the legendary General Electric CEO, was infamous for firing the bottom 10% of his workforce every year, without exception. The company's market cap rose substantially during Welch's tenure, but his "rank and yank" ritual was divisive. If you knew your job was always
There is a limit on how many times a mammal can be cloned before suffering "mutational meltdown," Japanese scientists have discovered, after making 1,200 clones over two decades that started off with a single mouse.
NASA's chief on Tuesday said the US space agency will invest $20 billion to develop a base on the moon, while suspending its plans to create the lunar orbital space station known as Gateway.
You may not be able to hear it, but all solid materials make a sound. In fact, atoms—bound in lattices of chemical bonds—are never silent nor still: Under the placid surface of each and every object in our surroundings, a low hum hovers or a high-energy squeak titters.
Cycles in the growth and decay of Antarctica's ice sheets once shaped marine biological productivity thousands of miles away in the subtropical ocean, according to new research led by scientists at the University of Wisconsin-Madison. The study, published in the Proceedings of

Emotional Intelligence (EI) training can improve employee well-being and prevent burn-out in high-stress environments, University of Queensland research has found. Dr. Jemma King from UQ's School of Psychology said EI training has proven beneficial for high performance
Global navigation satellite systems (GNSS), which include GPS, are traditionally used for positioning, timing, and mapping information. In an open-access study published Feb. 27 in Geophysical Research Letters, MIT Haystack Observatory scientists report using existing GNSS
Flooding, drought, and the loss of soil and nutrients are well-known challenges in agricultural catchments. Climate change is making these problems more pronounced. More intense rainfall leads to more runoff and erosion in fields, while longer dry periods increase the need to
When holidays or pandemics shut down schools, gender differences in children's reading habits widen; boys stop reading, while girls continue, according to a new study from the University of Copenhagen. The researchers say their findings suggest that boys are more dependent on
A Korea Institute of Materials Science (KIMS) research team, led by Dr. Dahee Park at the Hydrogen Energy Materials Research Center, has successfully developed a high-performance catalyst that significantly enhances the oxygen evolution reaction (OER), a key process in alkaline
Astronomers have an answer for a long-running mystery in astrophysics: why is the growth of supermassive black holes so much lower today than in the past? A study using NASA's Chandra X-ray Observatory and other X-ray telescopes found that supermassive black holes are unable to
A fascination with fish gills has led researchers at Cornell to develop a bio-inspired approach to mixing heat and molecules in fluids—findings that could inform future biomedical devices, heat exchangers and soft robotics.
An analysis of ancient grape seed DNA reveals the earliest known instance of humans in France purposefully cloning plants—including for pinot noir grapes

Have you ever been in the woods and wondered what bug you're hearing or which bird is singing? These days, new technologies are helping both scientists and the public identify what's trilling, scuttling, tweeting, rustling, or slithering around a given area.
In 2016, Antarctic sea ice, which had previously shown record expansion, shifted rapidly toward unusually low levels. This abrupt shift left scientists scratching their heads, wondering why it had vanished so quickly despite years of growth. A new study published in the journal
Following the beginning of the COVID-19 outbreak, lateral flow assays (LFAs)—the category of test strips in which the presence or lack of a pink line indicates whether a specific molecule, like a drug or a virus, has been detected—became household items. Yet despite their
In a new study, Northwestern University scientists explored how snow flies—small, wingless insects that crawl across snow to find mates and lay eggs—survive in freezing cold temperatures. They discovered this snow-dwelling fly uses a surprising combination of strategies: it
