Did ancient Earth life escape our solar system?
You’ve heard of panspermia, the idea that life exists throughout space and was carried to Earth by comets? What if the reverse occurred, with microbes on Earth ejected into space by asteroid impacts, escaping into the solar system billions of years ago?
Callum Roberts: ‘Sharks do bite people, they do kill people, but it’s more error than intention’
Callum Roberts is professor of marine conservation at York University and was chief scientific adviser on Blue Planet 2. His new book, Reef Life, details a life spent in the oceans studying the marine ecosystem. How was your first dive?It…
How Scientists Got Climate Change So Wrong – The New York Times
For decades, most scientists saw climate change as a distant prospect. We now know that thinking was wrong. This summer, for instance, a heat wave in Europe penetrated the Arctic, pushing temperatures into the 80s across much of the Far…
Warning system for aviation exposure to solar energetic particles (WASAVIES)
(National Institute of Information and Communications Technology (NICT)) A research group led by the National Institute of Information and Communications Technology (NICT), the Japan Atomic Energy Agency (JAEA), and the National Institute of Polar Research (NIPR) succeeded to develop a WArning System for AVIation Exposure to Solar energetic particles (WASAVIES), which can estimate radiation dose due to solar energetic particles in real-time just after the solar flare occurrence.
Turbulence creates ice in clouds
(Leibniz Institute for Tropospheric Research (TROPOS)) Vertical air motions increase ice formation in mixed-phase clouds. This correlation was predicted theoretically for a long time, but could now be observed for the first time in nature. This result was published by a team from TROPOS in npj Climate and Atmospheric Science, an Open Access journal published by Nature Research. Using laser and radar equipment, the team measured the vertical air velocity and ice formation in thin mixed-phase clouds.
Bushfires on east coast of Australia out of control
(NASA/Goddard Space Flight Center) An unprecedented number of bushfires have erupted on the east coast of Australia due to hot, dry, windy weather. Smoke billows from the scores of bushfires on Australia east coast in this image captured by NASA’s Terra satellite on Nov. 8, 2019, using the Moderate Resolution Imaging Spectroradiometer (MODIS) instrument onboard.
Carbon dioxide capture and use could become big business
Capturing carbon dioxide and turning it into commercial products, such as fuels or construction materials, could become a new global industry, according to a new study.
Plants and fungi together could slow climate change
A new global assessment shows that human impacts have greatly reduced plant-fungus symbioses, which play a key role in sequestering carbon in soils. Restoring these ecosystems could be one strategy to slow climate change.
TESS spacecraft is finding hundreds of exoplanets
… and it’s poised to find thousands more. But will we find another Earth?
Despite a Warmer, Wetter World, There May Be Less Water Available for Human Use, Study Finds
In a warmer world, plants could consume more water than they currently do, leaving less for human consumption and activities, according to a new study published in the journal Nature Geoscience. This future shortage is despite an increase in precipitation…
