Astronomers discover ancient brown dwarf with lithium deposits intact
Brown dwarfs, also known as "coffee colored dwarfs" or "failed stars" are the natural link between stars and planets. They are more massive than Jupiter but now sufficiently to burn hydrogen, which is the fuel the stars use to shine. For that reason.....»»

Researchers discover previously unknown gene that indirectly promotes photosynthesis in blue-green algae
Cyanobacteria—also called blue-green algae—are known as the "plants of the ocean" because they carry out photosynthesis on a gigantic scale, produce oxygen and extract the greenhouse gas CO2 from the environment. However, to do this they need add.....»»
Astronomers detect radio halo in a massive galaxy cluster
An international team of astronomers has performed radio observations of a massive galaxy cluster known as ACT-CL J0329.2-2330, which resulted in the detection of a new radio halo in this cluster. The finding was reported in a research paper publishe.....»»
Pyrite may contain valuable lithium, a key element for green energy
There's a reason airlines won't let you put your laptop in your checked luggage; the lithium-ion battery poses a serious fire hazard. But why? Lithium is incredibly reactive. For instance, pure lithium violently interacts with seemingly innocuous wat.....»»

Aboriginal people made pottery, sailed to distant islands thousands of years before Europeans arrived
Pottery was largely unknown in Australia before the recent past, despite well-known pottery traditions in nearby Papua New Guinea and the islands of the western Pacific. The absence of ancient Indigenous pottery in Australia has long puzzled research.....»»
A machine learning-based approach to discover nanocomposite films for biodegradable plastic alternatives
The accumulation of plastic waste in natural environments is of utmost concern, as it is contributing to the destruction of ecosystems and is causing harm to aquatic life. In recent years, material scientists have thus been trying to identify all-nat.....»»
Physicists solve puzzle about ancient galaxy found by Webb telescope
Last September, the James Webb Space Telescope, or JWST, discovered JWST-ER1g, a massive ancient galaxy that formed when the universe was just a quarter of its current age. Surprisingly, an Einstein ring is associated with this galaxy. That's because.....»»
A supernova caused the BOAT gamma ray burst, JWST data confirms
