Medical Xpress / Why we sleep poorly in new environments: A brain circuit that keeps animals awake
You check into a hotel and toss and turn all night, but your sleep improves the following night. Scientists at Nagoya University wanted to understand why this happens. Working with mice, they have identified a group of neurons ...
Phys.org / Spider spinneret evolution: How a genome duplication event 438 million years ago set the stage
Scientists have uncovered a 400-million-year-old genetic secret that gave spiders the ability to produce silk and weave their webs. Spiders didn't begin their journey on Earth in the same way as they are known today. Arthropods ...
Phys.org / The first headbutting paravian: Bird-like dinosaur likely used thick skull to win over mates
Whether it's digging up weathered bones from a paleontological site or reexamining forgotten trays in museum and university collections, the study of dinosaurs still throws up something new.
Phys.org / NASA fuels its moon rocket in a crucial test to decide when Artemis astronauts will launch

Phys.org / Perseverance rover completes first AI-planned drive on Mars
NASA's Perseverance Mars rover has completed the first drives on another world that were planned by artificial intelligence. Executed on Dec. 8 and 10, and led by the agency's Jet Propulsion Laboratory in Southern California, ...
Phys.org / Identifying mechanisms that support nanoparticle therapy for autoimmune diseases
Northwestern Medicine scientists in the laboratory of Stephen Miller, Ph.D., professor emeritus of Microbiology–Immunology, have identified the cellular and molecular mechanisms required for the antigen-specific tolerance ...
Phys.org / 2D discrete time crystals realized on a quantum computer for the first time
Physical systems become inherently more complicated and difficult to produce in a lab as the number of dimensions they exist in increases—even more so in quantum systems. While discrete time crystals (DTCs) had been previously ...
Phys.org / AI challenges established norms in higher education
Studies from the Department of Communication and Learning in Science show that AI tools such as ChatGPT are not merely being used as support in students' studies. In fact, they may be reshaping how students perceive knowledge ...
Phys.org / Even larvae mind the social bubble: How they adjust their behavior in response to social surroundings
Imagine enjoying a tasty dinner alone at home—you may freely indulge without worrying about others. Now imagine sharing the same meal with friends or colleagues: depending on the social context, you may find yourself eating ...
Phys.org / Not an artifact, but an ancestor: Why a German university is returning a Māori taonga
