How much longer will the oxygen-rich atmosphere be sustained on Earth?
(Toho University ) Earth’s modern atmosphere contains copious amounts of molecular oxygen (O2), representing an important remotely detectable sign of life. However, a fundamental question of how much longer the Earth’s oxygen-rich atmosphere will persist into the far future remains uncertain. A new study finds that a highly-oxygenated atmosphere is not a permanent feature even for Earth, which has implications for the search for life beyond the solar system.
Speaking the truth: Pacific Island countries lead the world in reporting on global warming – Monash Lens
Pacific islanders didn’t need US President Joe Biden to tell them that climate change poses “an existential threat”. They’ve been warning the West for years. Climate change communication researcher Tahnee Burgess has examined how Pacific Island journalists reported on global…
What is a quasar?
A quasar is an extremely bright and distant point-like source visible to radio telescopes. The source is a so-called Active Galactic Nucleus, fueled by a supermassive black hole.
Climate adaptation: we need local solutions to adapt to global warming – EU News
The European Committee of the Regions (CoR) welcomes the new EU Strategy on Adaptation to Climate Change adopted by the European Commission on 24 February 2021. The CoR regrets, however, that even though it enables the move from planning to…
Agents of food-borne zoonoses confirmed to parasitise newly-recorded in Thailand snails
(Pensoft Publishers) Parasitic flatworms known as agents of food-borne zoonoses were confirmed to use several species of thiarid snails, commonly found in freshwater and brackish environments in southeast Asia, as their first intermediate host. These parasites can cause severe ocular infections in humans who consume raw or improperly cooked fish that have fed on parasitised snails. The study, conducted in South Thailand, is published in the peer-reviewed open-access journal Zoosystematics and Evolution.
Warming may promote spread of invasive blue catfish
(Virginia Institute of Marine Science) A new study by researchers at William & Mary’s Virginia Institute of Marine Science suggests that continued warming of Atlantic coastal waters may enhance the spread of invasive blue catfish within the Chesapeake Bay and other estuaries along the U.S. East Coast.
Astrophysicists design âradically differentâ world map
You know the old problem of how to portray the round globe of Earth on a flat map? Now a trio of map experts has worked together to solve this problem. Their new map is 2-sided and round.
AI tames data volumes for automated driving
(Karlsruher Institut für Technologie (KIT) ) Large data volumes arise when testing highly automated vehicles. The new KIsSME project reduces data volumes to save storage capacity, power, and evaluation expenditure and, at the same time, at compressing data to enhance vehicle safety. Algorithms based on AI select data in the driving mode and sort them into scenario catalogs. Within the project funded by the Federal Ministry for Economic Affairs, Karlsruhe Institute of Technology (KIT) supplies data from test drives and simulations.
Post-wildfire landslides becoming more frequent in southern California
(American Geophysical Union) Southern California can now expect to see post-wildfire landslides occurring almost every year, with major events expected roughly every ten years, a new study finds. The results show Californians are now facing a double whammy of increased wildfire and landslide risk caused by climate change-induced shifts in the state’s wet and dry seasons, according to researchers who mapped landslide vulnerability in the southern half of the state.
James Webb Space Telescope â Hubbleâs successor â to launch in October
The James Webb Space Telescope is the worldâs most complex infrared telescope, built for a wide range of research projects. NASA is now targeting October 31 for its launch on an Ariane 5 rocket from French Guiana.
