Cloudy days are rare in the thin, dry atmosphere of Mars. Clouds are typically found at the planet's equator in the coldest time of year, when Mars is the farthest from the Sun in its oval-shaped orbit. But one full Martian year ago—two Earth years—scientists noticed clouds forming over NASA's Curiosity rover earlier than expected.

A Russian Soyuz rocket carrying 36 UK telecommunication and internet satellites blasted off from the Vostochny cosmodrome in Russia's Far East on Friday, the space agency said.

Science and art collide in a new British exhibition which opened on Friday and hopes to raise awareness about the environmental impact of eating meat, while promising a guilt-free look at the "difficult problem".

Biologists studying Southern California bobcats found a mother and three kittens this spring in an unusual den in a cavity up in a tree in an area intensely burned by a huge 2018 wildfire west of Los Angeles, the National Park Service said.

In 2015, nearly half of Hawaii's coral reefs were affected by the most severe bleaching event to date. Coral bleaching occurs when warmer-than-normal ocean temperatures prompt corals to expel the algae that normally live inside them and on which the corals rely for food.

About 36 million people have blindness including 1 million children. Additionally, 216 million people experience moderate to severe visual impairment. However, STEM (science, technology, engineering and math) education maintains a reliance on three-dimensional imagery for education. Most of this imagery is inaccessible to students with blindness. A breakthrough study by Bryan Shaw, Ph.D.,...

The 22nd SpaceX cargo resupply mission carrying scientific research and technology demonstrations launches to the International Space Station from NASA's Kennedy Space Center in Florida no earlier than June 3. Experiments aboard include studying how water bears tolerate space, whether microgravity affects symbiotic relationships, analyzing the formation of kidney stones, and more.

As part of preparing for an experiment aboard the International Space Station, researchers explored new ways to culture living heart cells for microgravity research. They found that cryopreservation, a process of storing cells at -80°C, makes it easier to transport these cells to the orbiting lab, providing more flexibility in launch and operations schedules. The process could benefit other...

A team of researchers offer new insight on conversion factors of greenhouse gases into their CO2 equivalent. The publication in Science Advances puts forward the economic benefits of periodically reassessing conversion factors according to scenarios of global warming.

Centuries-old smoke particles preserved in the ice reveal a fiery past in the Southern Hemisphere and shed new light on the future impacts of global climate change, according to new research published in Science Advances.

A new study of dozens of wild fish species commonly consumed in the Peruvian Amazon says that people there could suffer major nutritional shortages if ongoing losses in fish biodiversity continue. Furthermore, the increasing use of aquaculture and other substitutes may not compensate. The research has implications far beyond the Amazon, since the diversity and abundance of wild-harvested foods is...

This image shows the spiral galaxy NGC 5037, in the constellation of Virgo. First documented by William Herschel in 1785, the galaxy lies about 150 million light-years away from Earth. Despite this distance, we can see the delicate structures of gas and dust within the galaxy in extraordinary detail. This detail is possible using Hubble's Wide Field Camera 3 (WFC3), whose combined exposures...

Climate change will make outbreaks of West Nile virus more likely in the UK within the next 20-30 years, scientists say.

The population of the critically endangered Saiga antelope has more than doubled since 2019, Kazakhstan said Friday, giving conservationists fresh hope for the steppe-dwelling animal's long-term survival.

Once on the verge of extinction, the Iberian lynx population in Spain and Portugal has risen more than 10-fold over the past 18 years, the Spanish government said Friday.

Microbiologists at the U.S. Naval Research Laboratory are preparing experimental samples of fungi to send for a ride around the moon tentatively scheduled for later in 2021 or early 2022.

An analysis led by North Carolina State University researchers found counties with more socially vulnerable populations had a higher density of natural gas pipelines overall.

As the cleanest renewable energy, hydrogen energy has attracted special attention in recent research. Yet the commercialization of traditional proton exchange membrane fuel cells (PEMFCs), which consume hydrogen and produce electricity, is seriously restricted due to the chemical reaction of PEMFCs cathode largely reliying on expensive platinum-based catalysts.

An international archaeological study, led by researchers from the Culture and Socio-Ecological Dynamics (CaSEs) research group at Pompeu Fabra University, has advanced in the understanding and preservation of archaeological sites and in improving their analysis and surveying, thanks to the application of pXRF (portable X-ray fluorescence analysis) to anthropogenic sediments in Africa. It is a...

Professor Yao Huajian's research group from the School of Earth and Space Sciences of the University of Science and Technology of China (USTC), in cooperation with Dr. Piero Poli from Grenoble-Alpes University of France, combined the unique resolution reflected body waves (P410P and P660P) retrieved from ambient noise interferometry with mineral physics modeling, to shed new light on transition...

Protons—subatomic particles with a positive electric charge—are one of the first particles to have formed after the universe began and are a constituent of every atom in existence today. The movement of protons plays a key role in energy conversion processes, such as photosynthesis and respiration, in biological systems. In addition, proton conduction is an important factor for hydrogen fuel...

The ancient burrowers of the seafloor have been getting a bum rap for years.

The ethical practices, dilemmas and challenges of classroom research involving child language learners are the focus of a new book edited by Dr. Annamaria Pinter of the University of Warwick's Department of Applied Linguistics and Dr. Harry Kuchah of the University of Leeds.

Scandinavian companies have been less than successful at developing software abroad. But there are scientific answers to the challenge.
