An endangered fish in California might use its internal clock to decide when to migrate, according to a study by the University of Cincinnati.

A team of Israeli and American researchers funded by grants from the National Geographic Society and the Israel Science Foundation has uncovered new evidence that an earthquake may have caused the destruction and abandonment of a flourishing Canaanite palatial site about 3,700 years ago.

As missions like NASA's Hubble Space Telescope, TESS and Kepler continue to provide insights into the properties of exoplanets (planets around other stars), scientists are increasingly able to piece together what these planets look like, what they are made of, and if they could be habitable or even inhabited.

Recent protests across the United States and the world have put a magnifying glass on issues of diversity and equity. A new study explores the ways in which these issues go all the way to the top of the corporate ladder.

A team from Osaka City University, in collaboration with other international partners, has demonstrated a reliable, precise, microscope-based thermometer using quantum technology that measures the temperature fo microscopic animals. The technology detects temperature-dependent properties of quantum spins in fluorescent nanodiamonds.

Wind shear was affecting both Tropical Storm Paulette and Rene in the Atlantic Ocean on Sept. 11. Infrared imagery from NASA's Aqua satellite showed that strong southwesterly wind shear pushed against Paulette creating a wedge-shaped storm.

Researchers have shown why intense, pure red colors in nature are mainly produced by pigments, instead of the structural color that produces bright blue and green hues.

Males and females share the vast majority of their genomes. Only a sprinkling of genes, located on the so-called X and Y sex chromosomes, differ between the sexes. Nevertheless, the activities of our genes—their expression in cells and tissues—generate profound distinctions between males and females.

Lasing—the emission of a collimated light beam of light with a well-defined wavelength (color) and phase—results from a self-organization process, in which a collection of emission centers synchronizes itself to produce identical light particles (photons). A similar self-organized synchronization phenomenon can also lead to the generation of coherent vibrations—a phonon laser, where phonon...

Infrared imagery from NASA's Aqua satellite showed an elongated Tropical Storm Rene being battered by wind shear in the Central Atlantic Ocean. Tropical cyclones that appear less than round are likely being affected by wind shear or outside winds transitioning into an extra-tropical cyclone or taking on the elongated appearance of a weather front. Infrared imagery from NASA's Aqua satellite showed...

The ongoing COVID-19 pandemic has shown that the world needs technology that can quickly and accurately identify invisible dangers, including harmful substances or airborne environmental pollutants. Colorimetric sensors—devices that intuitively reveal information about their environment through color changes—are an attractive option in this regard. But, for more people to benefit from these...

Ling Li has a lesson in one of his mechanical engineering courses on how brittle materials like calcium carbonate behave under stress. In it, he takes a piece of chalk composed of the compound and snaps it in half to show his students the edge of one of the broken pieces. The break is blunt and straight.

NOAA/NASA's Suomi NPP satellite captured these series of images (made into an animated GIF) showing the winds changing direction on Sep. 06, 2020 when choking clouds of brown smoke began to billow and cascade into the Pacific Ocean. (Dates displayed in lower left hand corner.) By Sep. 10, the smoke cloud had traveled over 1,300 miles. The square miles of smoke in the image below totals 963,269....

The discovery was heartbreaking for biologists, who consider the mountain lions of Southern California to be among the most threatened mammals in North America: a young male with the distortions of inbreeding—a tail kinked like the letter "L" and only one descended testicle.

Despite the importance of changes in root architecture to exploit local nutrient patches, mechanisms integrating external nutrient signals into the root developmental program remain poorly understood. "Here, we show for the first time that local ammonium supply stimulates the accumulation of auxin in the root vasculature and promotes auxin diffusion and lateral root formation to build a highly...

Galapagos tourist guides are being retrained to catalog the islands' famous biodiversity.

Researchers working on the Seeds of Discovery (SeeD) initiative, which aims to facilitate the effective use of genetic diversity of maize and wheat, have genetically characterized 79,191 samples of wheat from the germplasm banks of the International Maize and Wheat Improvement Center (CIMMYT) and the International Center for Agricultural Research in the Dry Areas (ICARDA).

An international team of researchers led by biologists from Heinrich Heine University Düsseldorf (HHU) has examined how seed formation is coordinated with fruit growth. In the latest edition of the journal Current Biology, they explain the genetic control mechanisms underlying the process.

Last month was the second-worst August on record for deforestation in the Brazilian Amazon, according to official figures released Friday, sparking new criticism of far-right President Jair Bolsonaro's environmental policies.

The ongoing COVID-19 pandemic has shown how important it is to have tools that can rapidly diagnose viral infectious diseases. Aside from the SARS-CoV-2 virus, which has currently taken the spotlight, the zika, dengue, and chikungunya viruses have also become major threats to human health in many parts of the world, particularly in tropical countries. All three viruses are transmitted by...

Graphene is a modern wonder material possessing unique properties of strength, flexibility and conductivity whilst being abundant and remarkably cheap to produce, lending it to a multitude of useful applications—especially true when these 2-D atom-thick sheets of carbon are split into narrow strips known as Graphene Nanoribbons (GNRs).

Crews battled sprawling wildfires up and down the US West Coast on Friday in a wave of infernos that have killed 15 people and forced more than half a million others to flee their homes.

The science community has responded to the COVID-19 pandemic with such a flurry of research studies that it is hard for anyone to digest them all, underscoring a long-standing need to make scientific publication more accessible, transparent and accountable, two artificial intelligence experts assert in a data science journal.

How much our world will warm this century depends on the actions we take in coming decades. In order to keep global temperature rise below 1.5°C and avoid dangerous levels of warming, governments need to know how much carbon they can emit, and over what timeframe.
