Phys.org / Failed supernova provides clearest view yet of a star collapsing into a black hole
Astronomers have watched a dying star fail to explode as a supernova, instead collapsing into a black hole. The remarkable sighting is the most complete observational record ever made of a star's transformation into a black ...
Phys.org / NASA, SpaceX shoot for predawn Crew-12 launch with sonic boom possible
The Space Coast's first human spaceflight of the year is on tap for early Friday morning as NASA and SpaceX aim to send up a mission to the International Space Station, and also bring back the rocket's booster that could ...
Dialog / Rethinking climate change: Natural variability, solar forcing, model uncertainties, and policy implications
Current global climate models (GCMs) support with high confidence the view that rising greenhouse gases and other anthropogenic forcings account for nearly all observed global surface warming—slightly above 1 °C—since ...
Phys.org / Football-sized fossil creature may have been one of the first land animals to eat plants
Life on Earth started in the oceans. Sometime around 475 million years ago, plants began making their way from the water onto the land, and it took another 100 million years for the first animals with backbones to join them. ...
Phys.org / Scientists uncover Iron Age origins of Vietnamese tooth blackening practices
Not everyone wants their teeth to be white and gleaming. Tooth blackening is a recognized part of modern Vietnamese culture, and a recent discovery hints that the roots of this practice may stretch all the way back to the ...
Phys.org / Nature's 'engine is grinding to a halt' as climate change gains pace, says study
Many ecologists hypothesize that, as global warming accelerates, change in nature must speed up. They assume that as temperatures rise and climatic zones shift, species will face local extinction and colonize new habitats ...
Phys.org / Experiment relies on pulsars to probe dark matter waves
Dark matter is a type of matter that is predicted to make up most of the matter in the universe, yet it is very difficult to detect using conventional experimental techniques, as it does not emit, absorb, or reflect light. ...
Medical Xpress / 'Punk wellness': China's stressed youth mix traditional medicine and cocktails
In a softly lit Shanghai bar, graduate student Helen Zhao stretched out both wrists to have her pulse taken—the first step to ordering the house special, a bespoke "health" cocktail based on traditional Chinese medicine.
Phys.org / The 'Little red dots' observed by Webb were direct-collapse black holes
The James Webb Space Telescope (JWST) was designed to look back in time and study galaxies that existed shortly after the Big Bang. In so doing, scientists hoped to gain a better understanding of how the universe has evolved ...
Phys.org / Elephant trunk whiskers exhibit material intelligence, revealing the secret behind an amazing sense of touch
A new study from an interdisciplinary German research collaboration, led by the Haptic Intelligence Department at the Max Planck Institute for Intelligent Systems (MPI-IS), reveals the secret to the gentle dexterity of the ...
Phys.org / Unique 'inside out' planetary system reveals rocky outer world
A global team of astronomers, led by the University of Warwick, have used a European Space Agency (ESA) telescope to discover a planetary system that turns our understanding of planet formation upside down, with a distant ...
Phys.org / Jupiter-family comet 41P/TGK slows down and reverses spin after perihelion
New analysis on 2017 Hubble images of the Jupiter-family comet, 41P/Tuttle–Giacobini–Kresak (41P/TGK), indicates that the comet underwent a spin reversal between April and December 2017. While this behavior is not unheard ...
