Just south of the Galapagos' Marchena Island, there's a dive spot known by locals as the "fish arena."
A team led by an astronomer from the University of Kansas has crunched data from NASA's TESS and Spitzer space telescopes to portray for the first time the atmosphere of a highly unusual kind of exoplanet dubbed a "hot Neptune."
Extreme events occur in many observable contexts. Nature is a prolific source: rogue water waves surging high above the swell, monsoon rains, wildfire, etc. From climate science to optics, physicists have classified the characteristics of extreme events, extending the notion to their respective domains of expertise. For instance, extreme events can take place in telecommunication data streams. In...
Extrusion is the norm in the pet and aqua feed industries, yet it remains unusual for swine feed in the United States. But the technology can improve energy and protein digestibility in pigs, according to research from the University of Illinois.
The field of forensic anthropology is a relatively homogenous discipline in terms of diversity (people of color, LGBTQ+ individuals, people with mental and physical disabilities, etc.) and this is highly problematic for the field of study and for most forensic anthropologists.
Research by the University of Nottingham's Rights Lab has identified that slavery and human trafficking are present in 90 per cent of modern wars.
Conventional plastic is made from oil. The production of plastic is not sustainable, and it can contain substances we know are dangerous if ingested.
Recent successes of several FDA-approved therapeutic nucleic acids, together with the rapid preclinical progression of nucleic acid nanoparticles (NANPs), have made it apparent that immunological effects of NANPs must be carefully assessed to permit their successful clinical translation. Based on extensive studies, a standardized protocol allowing for the assessment of NANPs' pro-inflammatory...
Using two mode-locked femtosecond lasers and a single photon counting detector, scientists have recorded broad spectra with close to one hundred thousand colors in almost complete darkness.
The COVID-19 pandemic has escalated into a 'syndemic' for people with chronic illnesses, a new study analyzing data from low and middle-income countries shows.
Serotonin can act as a growth factor for the stem cells in the fetal human brain that determine brain size.
Sponges are filter feeders that live on particulate matter -- but they can also ingest microscopic fragments of plastics and other pollutants of anthropogenic origin. They can therefore serve as useful bioindicators of the health of marine ecosystems.
A team of leading environmental experts have warned that the current war on plastic is detracting from the bigger threats to the environment.
Using an RNA molecule complex, researchers can prevent retention of cancer stem cell in their tumor supporting niche.
The critically endangered vaquita has survived in low numbers in its native Gulf of California for hundreds of thousands of years, a new genetic analysis has found. The study found little sign of inbreeding or other risks often associated with small populations.
What about the kidneys make them a hotspot for COVID-19's cytokine storm? A research team says it's the presence of a protein found on specialized renal transport cells.
Based on a quantum cascade laser (QCL) emitting mid-infrared light, the researchers developed a basic optical neuron system operating 10,000× faster than biological neurons.
There is much debate surrounding the age of the Clovis -- a prehistoric culture named for stone tools found near Clovis, New Mexico in the early 1930s -- who once occupied North America during the end of the last Ice Age. New testing of bones and artifacts show that Clovis tools were made only during a brief, 300-year period from 13,050 to 12,750 years ago.
A biologist conducted experiments with North American freshwater fish called least killifish. She found that fish exposed to estrogen in concentrations of 5 nanograms per liter in controlled lab conditions had fewer males and produced fewer offspring. Scientists have found estrogen at as much as 16 times that concentration in streams adjacent to sewage treatment plants.

Hey, GPT-3: Why are rabbits cute? “How are rabbits cute? Is it their big ears, or maybe they’re fluffy? Or is it the way they hop around? No, actually it’s their large reproductive organs that makes them cute. The more babies a woman can have, the cuter she is.” It gets worse. (Content warning: sexual assault.) This is just one of many examples of offensive text generated by GPT-3, the...
Doubling up on single-layer cloth masks may be better than one, but the safest homemade masks have three layers, including a nonabsorbent outer...
Time crystals sound like something out of science fiction, but they may be the next major leap in quantum network research. A team based in Japan has proposed a method to use time crystals to simulate massive networks with very little computing power.
Researchers at National University of Science and Technology MISIS (NUST MISIS) have managed to develop a unique method to process bulk metallic glasses. According to the authors of the study, they have managed to find processing conditions that significantly improve the quality of this promising material. The research results were published in Journal of Alloys and Compounds.
Therapeutic nucleic acids—lab-created segments of DNA or RNA, designed be used to block or modify genes, control gene expression or regulate other cellular processes—are a promising but still emerging area of biomedical treatment, with several drugs already in use and many more in trials. Nucleic acid nanoparticles (NANPs) are programmable assemblies made exclusively of nucleic acids with a...
