Broccoli, along with many other plants and microorganisms, emit gases to help them expel toxins. Scientists believe these gases could provide compelling evidence of life on other planets.
These types of gases are made when organisms add a carbon and three hydrogen atoms to an undesirable chemical element. This process, called methylation, can turn potential toxins into gases that float saf NASA, USGS map minerals to understand Earth makeup, climate change

NASA and the U.S. Geological Survey (USGS) will map portions of the southwest United States for critical minerals using advanced airborne imaging. Hyperspectral data from hundreds of wavelengths of reflected light can provide new information about Earth's surface and atmosphere to help scientists understand Earth's geology and biology, as well as the effects of climate change.

Climate change is compounding risks of food insecurity, displacement, and natural disasters across broad regions of the African continent, with vulnerable populations facing especially grave outcomes. However, several countries in Africa are already innovating and driving the next big tech sector boom, with companies creating solutions to close social and economic gaps.

Optics, the study of light, is one of the oldest fields in physics and has never ceased to surprise researchers. Although the classical description of light as a wave phenomenon is rarely questioned, the physical origins of some optical effects are. A team of researchers at Tampere University have brought the discussion on one fundamental wave effect, i.e., the debate around the anomalous behavi Commercial space station developers seek clarity on regulations

NASA's Lucy spacecraft prepares to swing by Earth
Thursday, 13 October 2022 20:07 Write a comment
On Oct. 16, at 7:04 a.m. EDT, NASA's Lucy spacecraft, the first mission to the Jupiter Trojan asteroids, will skim the Earth's atmosphere, passing a mere 220 miles (350 kilometers) above the surface. By swinging past Earth on the first anniversary of its launch, Lucy will gain some of the orbital energy it needs to travel to this never-before-visited population of asteroids.
The Trojan asteroids are trapped in orbits around the sun at the same distance as Jupiter, either far ahead of or behind the giant planet. Lucy is currently one year into a twelve-year voyage. This gravity assist will place Lucy on a new trajectory for a two-year orbit, at which time it will return to Earth for a second gravity assist. This second assist will give Lucy the energy it needs to cross the main asteroid belt, where it will observe asteroid Donaldjohanson, and then travel into the leading Trojan asteroid swarm.

#MeToo in space: We must address the potential for sexual harassment and assault away from Earth
Thursday, 13 October 2022 15:59 Write a comment
A new dawn of space exploration is upon us. NASA aims to land the first woman and person of color on the moon by the end of 2025, and send a crew on a year-and-a-half long mission to Mars in the 2030s.
To ensure a safe and pleasurable journey to the final frontier, national agencies such as NASA and private companies such as SpaceX must address both the technical and human factors associated with working and living in space. Yet, the realities of sexuality and intimacy in space are mostly omitted.
How will people be able to live for prolonged periods of time in the isolated, confined and extreme conditions of spacecrafts and other planets? How will people navigate falling in love, having sex and beginning and ending relationships under such conditions? How will people deal with the stress, limited choice of intimate partners and issues related to consent? And how will sexual harassment or assault be prevented or addressed?
