Conservationists in Ecuador have found a nest of endangered leatherback sea turtles, a whopper of a species that can weigh up to a tonne and be three meters (10 feet) long.

Pacific island leaders will hold a virtual summit next week to demand urgent worldwide action on climate change ahead of UN-brokered talks on the issue.

The US space agency NASA awarded contracts to four companies on Thursday to collect lunar samples for $1 to $15,000, rock-bottom prices that are intended to set a precedent for future exploitation of space resources by the private sector.

Every year, pounding rains wash away mountains of plastic waste from the streets of Jakarta, with some of it ending up as far away as Bali's beaches. So scientists are turning to satellites to trace the rubbish and figure out how to tackle the problem.

Days after the discovery and swift disappearance of two shining metal monoliths half a world apart, another towering structure has popped up and then quickly vanished, this time from the pinnacle of a trail in California.

Researchers from University of Houston, Columbia University, Emory University, and University of Connecticut published a new paper in the Journal of Marketing that reviews factors that contribute to the disconnect between the data companies create and the productive use of that data.

That carbon nanotubes fluoresce is no longer a surprise. Finding a second level of fluorescence is surprising and potentially useful.

Organisms excrete DNA in their surroundings through metabolic waste, sloughed skin cells or gametes, and this genetic material is referred to as environmental DNA (eDNA).

Using a new variant to repair DNA will improve both safety and effectiveness of the much-touted CRISPR-Cas9 tool in genetic research, Michigan Medicine researchers say.

Researchers at the Garvan Institute of Medical Research have uncovered a new form of DNA modification in the genome of zebrafish, a vertebrate animal that shares an evolutionary ancestor with humans ~400 million years ago.

Call it a special delivery: after six years in space, Japan's Hayabusa-2 probe is heading home, but only to drop off its rare asteroid samples before starting a new mission.

Astronomers have taken a step towards understanding how the Moon might have formed out of a giant collision between the early Earth and another massive object 4.5 billion years ago.

Puerto Rico's Arecibo Observatory could still have a future after its vast telescope dramatically collapsed this week, US officials said Thursday.

Analysis from a University of Texas at Arlington assistant professor of public policy suggests that nationalistic governments around the globe are more likely to copy other nationalistic governments in responding to the current pandemic.

Hypersonic flight is conventionally referred to as the ability to fly at speeds significantly faster than the speed of sound and presents an extraordinary set of technical challenges. As an example, when a space capsule re-enters Earth's atmosphere, it reaches hypersonic speeds—more than five times the speed of sound—and generates temperatures over 4,000 degrees Fahrenheit on its exterior...

A recent study examining perceptions of power suggests that individuals with lower socioeconomic statuses are more likely to have a negative view of policy or decision-makers.

The crystalline solid BaTiS3 (barium titanium sulfide) is terrible at conducting heat, and it turns out that a wayward titanium atom that exists in two places at the same time is to blame.

Forest leaves are teeming with bacterial life—but despite the vast extent of bacteria-covered foliage across the world, this habitat, known as the phyllosphere, remains full of mysteries. How do bacteria spread from tree to tree? Do certain types of bacteria only live on certain types of trees?

Accelerating tree growth in recent years has been accompanied by a reduction in tree lifespan, which could eventually neutralize part of the increase in net uptake of carbon dioxide (CO2). This trade-off between tree growth and life expectancy applies to forests worldwide, including in the Amazon and other tropical regions, as well as temperate regions and the Arctic.

Rusted iron pipes can react with residual disinfectants in drinking water distribution systems to produce carcinogenic hexavalent chromium in drinking water, reports a study by engineers at UC Riverside.

For Black youth, an encounter with police by eighth grade predicts they will be arrested by young adulthood—but the same is not true for white youth, a new University of Washington study finds.

When Terrie Williams began hearing about the wide range of symptoms experienced by patients with COVID-19, she saw a connection between the various ways the disease is affecting people and the many physiological adaptations that have enabled marine mammals to tolerate low oxygen levels during dives.

A researcher at the University of Tartu described new associations between Neandertal DNA and autoimmune diseases, prostate cancer and type 2 diabetes.

Over a quarter of all proteins in a cell are found in the membrane, where they perform vital functions. To fulfill these roles, membrane proteins must be reliably transported from their site of production in the cell to their destination and correctly inserted into the target membrane. Researchers from the Heidelberg University Biochemistry Center (BZH) have succeeded in determining the...
