Phys.org / Ancient Alaskan site may help explain how the first people arrived in North America
New evidence has emerged that sheds light on the possible first people to populate the Americas. Dating of stone and ivory tools found at an archaeological site in Alaska suggests that these early pioneers traveled through ...
Phys.org / New hybrid films could cut costs for direct X-ray detectors
In medicine, security, nuclear safety and scientific research, X-rays are essential tools for seeing what remains hidden. The materials used to create X-ray detectors can be rigid, expensive and laborious to produce. But ...
Phys.org / Solid, iron-rich megastructure under Hawaii slows seismic waves and may drive plume upwelling
Mantle plumes beneath volcanic hotspots, like Hawaii, Iceland, and the Galapagos, seem to be anchored into a large structure within the core-mantle boundary (CMB). A new study, published in Science Advances, takes a deeper ...
Phys.org / JWST discovers a new extremely metal-poor dwarf galaxy
Using the James Webb Space Telescope (JWST), astronomers have discovered a new dwarf galaxy, which received designation CAPERS-39810. Further investigation of CAPERS-39810 revealed that it is an extremely metal-poor galaxy. ...
Phys.org / A student made cosmic dust in her lab—what she found could help us understand how life started on Earth
A Sydney Ph.D. student has recreated a tiny piece of the universe inside a bottle in her laboratory, producing cosmic dust from scratch. The results shed new light on how the chemical building blocks of life may have formed ...
Phys.org / The surprising power of a tiny, disordered protein in a mitochondrial supercomplex
For decades, scientists assumed that order drives efficiency. Yet in the bustling machinery of mitochondria—the organelles that crank out adenosine triphosphate (ATP), the universal "energy currency" of cells—one of the ...
Tech Xplore / Will AI put me out of a job? How artificial intelligence is being used in casino gaming
Will artificial intelligence put me out of a job? That's the lingering fear some employees in the gaming industry are contemplating as rapidly evolving technology is deployed in workplaces across the globe, including in casino ...
Phys.org / Researchers demonstrate organic crystal emitting red light from UV and green from near-infrared
Invisible light beyond the range of human vision plays a vital role in communication technologies, medical diagnostics, and optical sensing. Ultraviolet and near-infrared wavelengths are routinely used in these fields, yet ...
Phys.org / Weight-loss drugs are creating an environmental disaster—a new water-based method aims to change that
The world is in the middle of a peptide drug revolution. These short chains of amino acids—the building blocks of proteins—sit at the heart of some of the most successful medicines ever created, from weight-loss injections ...
Medical Xpress / Experimental pill dramatically reduces 'bad' cholesterol
An experimental pill called enlicitide slashed levels of low-density lipoprotein (LDL) cholesterol, commonly known as "bad" cholesterol, by up to 60%, according to a new phase three clinical trial published in the New England ...
Phys.org / Finger length could provide vital clue to understanding human brain evolution
The evolution of the human species is marked by an increase in brain size. Now new research suggests that could be partly dependent on increases in prenatal estrogen—revealed by looking at the length of a person's fingers. ...
Phys.org / Functional forecasting: Using Homeland Security exercises to evaluate storm decision support tool
In a paper in the Journal of Coastal and Riverine Flood Risk, a team from the University of Rhode Island discusses the novel application of Homeland Security exercises to evaluate emergency managers' use of their simulation ...
