NASA gave the green light on Friday to next week's launch of two astronauts aboard a SpaceX vessel—the first crewed space flight from US soil in nine years and a crucial step towards ending American dependence on Russian rockets.

Magnesium dimer (Mg2) is a fragile molecule consisting of two weakly interacting atoms held together by the laws of quantum mechanics. It has recently emerged as a potential probe for understanding fundamental phenomena at the intersection of chemistry and ultracold physics, but its use has been thwarted by a half-century-old enigma—five high-lying vibrational states that hold the key to...

Given the present-day rate of global sea-level rise, remaining marshes in the Mississippi Delta are likely to drown, according to a new Tulane University study.

Meiosis is essential to sexual reproduction. For almost 15 years, it has been commonly held that retinoic acid, a molecule derived from vitamin A, triggers meiosis in mammalian germ cells. Yet, in joint articles published in Science Advances, French researchers from the Institut de Biologie Valrose (CNRS / INSERM / Université Côte d'Azur) and the IGBMC (CNRS / INSERM / University of Strasbourg),...

Organisms carry long-term "memories" of their ancestral homelands that help them adapt to environmental change, according to a new study that involved raising chickens on the Tibetan Plateau and an adjacent lowland site.

A scientist at the University of Sydney has achieved what one quantum industry insider has described as "something that many researchers thought was impossible".

Much like people, fruit flies must decide when the time and place are right to make a move on a mate. Male fruit flies use cues such as age and pheromones to gauge their chances of success, but just how they do that on a molecular level was a mystery.

The two astronauts who will test drive SpaceX's brand new rocketship are classmates and friends, veteran spacefliers married to veteran spacefliers, and fathers of young sons.

Some wonders of nature continue happening despite the global pandemic, and sea turtle nesting season is no exception. In Florida, those turtles are off to a strong start.

NASA's Aqua satellite used infrared light to provide forecasters with a look at the temperatures of the cloud tops in Tropical Storm Mangga.

A new study highlights the need to engage Indigenous communities in managing sea otter population recovery to improve coexistence between humans and this challenging predator.

Aside from Indira Gandhi, Margaret Thatcher, and more recently Angela Merkel and Jacinda Ardern, women continue to be scarce in the halls of power.

A species of parasitic wasp discovered by chance could provide growers with a chemical-free way of controlling a major pest.

Take a look inside the cap of your favorite toothpaste, and you might see hard, white residue, a firm version of the smooth paste you squeeze onto your brush.

A new study by researchers at Duke University and RTI International finds that reusing oilfield water that's been mixed with surface water to irrigate farms in the Cawelo Water District of California's Kern County does not pose major health risks, as some opponents of the practice have feared.

Cornell researchers have sequenced and analyzed the genome of a single-celled alga that belongs to the closest lineage to terrestrial plants and provides many clues to how aquatic plants first colonized land.

University of California, San Diego researchers have confirmed that climate change helped produce the historic 43-day ocean heat wave that drew big crowds to San Diego beaches during the summer of 2018.

Today's computers use the presence or absence of charge (0s and 1s) to encode information, where the physical motion of charges consume energy and cause heat. A novel alternative is to utilize the wave quantum number of electrons by which information encoding is possible without physically moving the carriers. This study shows that manipulation of the wave quantum number is possible by controlling...

The United States is experiencing its steepest economic slide in modern history. Tens of millions of Americans have filed new unemployment claims as the coronavirus shutters businesses and forces companies to lay off staff.

The effects of coronavirus on the economy already appear bleak. Unemployment and government borrowing are soaring and a recession seems inevitable.

At least 106 people died in the fiercest cyclone to hit Bangladesh and eastern India since 1999, officials said Friday as aerial footage revealed immense flooding in coastal areas.

Archaeologists have found the bones of about 60 mammoths at an airport under construction just north of Mexico City, near human-built 'traps' where more than a dozen mammoths were found last year.

The COVID-19 pandemic is not only affecting almost every aspect of our daily lives, but also the environment. A German team, led by the Max Planck Institute for Chemistry and the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), now wants to find out how strong these effects are on the atmosphere. Over the next two weeks, as part of the Bluesky research programme,...

The Dark Energy Spectroscopic Instrument (DESI), installed on an Arizona mountaintop, was quickly moving through its testing stages and making headway toward the start of its 5-year observing run as project participants from around the world traveled to attend a DESI collaboration meeting in Tucson, Arizona, in early March.
