Phys.org / Nearby red dwarf star hosts at least four planets—with one in the habitable zone
In 2020, a study confirmed that two planets orbited the nearby red dwarf, GJ 887. Now, astronomers have confirmed the existence of two additional planets orbiting GJ 887 in a new study published in Astronomy and Astrophysics. ...
Phys.org / Mining the dark transcriptome: Synthesizing the first potential drug molecules from long noncoding RNA
A team from University of Toronto Engineering is the first to synthesize long noncoding RNA (lncRNA) outside the cell—a new approach to drug discovery that has already yielded some promising anti-inflammatory molecules. ...
Phys.org / 3D-printed photonic lanterns combine up to 37 multimode lasers into one fiber
Researchers have developed a microscopic 3D-printed optical device that can efficiently combine light from dozens of small semiconductor lasers into a single multimode optical fiber with very low loss. The team demonstrated ...
Phys.org / Could ultrasound help save hedgehogs?
Researchers at the University of Oxford have suggested that ultrasound-repellers could help reduce hedgehog deaths caused by cars. The proposal is based on new findings, published in Biology Letters, which demonstrate for ...
Phys.org / First absolute dating of Paleolithic paintings in the Dordogne
A research team led by a CNRS researcher has for the first time accurately determined the age of the cave paintings at Font-de-Gaume (Les Eyzies) in Dordogne (southwestern France), according to a study published on March ...
Phys.org / Salt may have pushed us further into Snowball Earth 700 million years ago
Our planet plunged into one of the most dramatic climate states in its long history, approximately 720–635 million years ago. During a period geologists call Snowball Earth, ice sheets crept from the poles all the way to ...
Phys.org / NASA finds extreme star collision in unlikely spot
A fleet of NASA missions has likely uncovered a collision between two ultradense stars in a tiny galaxy buried in a huge stream of gas. Astronomers have never seen this type of explosive event in an environment like this ...
Phys.org / Ancient parrot DNA reveals sophisticated, long-distance animal trade network pre-dating the Inca Empire
New analysis of ancient parrot DNA has revealed that vibrant Amazonian parrots were transported alive across the Andes to coastal Peru centuries before the Inca Empire, highlighting a sophisticated pre-Inca, long-distance ...
Phys.org / Antarctic waters DNA survey discovers many microbial genes new to science
The Southern Ocean—vast, boundless waters surrounding Antarctica—plays an outsized role in global climate, largely thanks to tiny drifting organisms called plankton that soak up carbon. Reporting in Nature Communications ...
Phys.org / Hybrid synthetic strategy unlocks previously unattainable molecular architectures
The molecular-scale design of materials is one of the major frontiers in modern science. Flat, highly conjugated organic molecules are already used in advanced technologies such as chemical sensors, optoelectronic devices, ...
Tech Xplore / Can AI read papers like a scientist? A new benchmark shows where LLMs fail
To stay up to date and work forward in their fields, scientists must have at their fingertips and in their minds thousands of published studies. Large language models (LLMs) show promise as a tool for exploring the vast scientific ...
Phys.org / Chemical shifts help track molecules breaking apart in real time
When molecules fall apart, their electric charge doesn't stay put—it rearranges as bonds stretch and break. An international team of scientists has now tracked these ultrafast changes in the small molecule fluoromethane ...
