Curiosity rover captures shining clouds on Mars

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.

Study uses candy-like models to make STEM accessible to visually impaired students

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.,...

SpaceX CRS-22 mission to space station launches water bears, squid, solar panels

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.

Researchers develop better ways to culture living heart cells on the International Space Station

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...

New CRISPR tools help contain mosquito disease transmission

Scientists have developed a genetics toolkit that helps pave the way to a gene drive designed to stop Culex mosquitoes from spreading disease. Much less studied than other genera, Culex mosquitoes spread devastating afflictions stemming from West Nile virus, Japanese encephalitis virus and the pathogen causing avian malaria.

Planetary Defense By the Numbers: May 2021

How many near-Earth objects have been found thus far? How big are they? Are there any left to discover? Find out the answers to these questions and more in this month's Planetary Defense: By the Numbers video. Video...

Lessening the cost of strategies to reach the Paris Agreement

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.

Declining biodiversity in wild Amazon fisheries threatens human diet

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...
