James Webb Space Telescope detects water vapor, sulfur dioxide and sand clouds in the atmosphere of a nearby exoplanet      (via sciencedaily.com)     Original source 

Astronomers have used recent observations made with the James Webb Space Telescope to study the atmosphere of the nearby exoplanet WASP-107b. Peering deep into the fluffy atmosphere of WASP-107b they discovered not only water vapor and sulfur dioxide, but even silicate sand clouds. These particles reside within a dynamic atmosphere that exhibits vigorous transport of material.

Dangerous bee virus less deadly in at least one US forest      (via sciencedaily.com)     Original source 

Researchers have found that the deadly deformed wing virus (DMV) in bees may have evolved to be less deadly in at least one U.S. forest. The findings could have implications for preventing or treating the virus in managed colonies, researchers said.

'Bouncing' comets could deliver building blocks for life to exoplanets      (via sciencedaily.com)     Original source 

How did the molecular building blocks for life end up on Earth? One long-standing theory is that they could have been delivered by comets. Now, researchers have shown how comets could deposit similar building blocks to other planets in the galaxy.

Galactic 'lightsabers': Answering longstanding questions about jets from black holes      (via sciencedaily.com)     Original source 

The one thing everyone knows about black holes is that absolutely everything nearby gets sucked into them. Almost everything, it turns out. Astrophysicists have now determined conclusively that energy close to the event horizon of black hole M87* is pushing outward, not inward. The researchers have also created a way to test the prediction that black holes lose rotational energy and to establish it's that energy that produces the incredibly powerful jets.

First evidence of how the Asian malaria mosquito is spreading drug-resistant malaria in Africa      (via sciencedaily.com)     Original source 

Research has led to the discovery of the role played by the Asian malaria mosquito (Anopheles stephensi) in the spread of drug and diagnosis-resistant malaria in Africa. Malaria is caused by a parasite which is spread by the bite of blood-sucking mosquitoes. According to the WHO, there were an estimated 247 million cases of malaria worldwide in 2021 with over 600,000 deaths, mostly in Africa.  Children under 5 accounted for about 80% of all malaria deaths in the region.
