Phys.org / IceCube detects break in cosmic neutrino spectrum, ruling out simple power-law model
A new study published in Physical Review Letters by the IceCube Collaboration reports evidence that the energy spectrum of astrophysical neutrinos is not a simple straight line.
Phys.org / In the world's economic 'black holes,' data still leak out
From satellite imagery to clandestine price reports, a new study draws on North Korea to explore economic activity in opaque regimes and information-scarce regions. North Korea is the blackest of economic black holes. Even ...
Phys.org / Mars's manganese 'bathtub ring' reveals ancient ocean timeline and its potential for life
Past research has indicated Mars's largest northern basin, Utopia Planitia, was once the location of a large body of water, but details surrounding when this body of water may have existed have not been resolved. Researchers ...
Phys.org / Why tipping fatigue is growing in Canada
Ever feel uncomfortable when a payment screen asks for a tip? We sure have. As tipping prompts become more widespread, more consumers are feeling uneasy or frustrated, but not always sure why.
Phys.org / Tardigrades reveal extreme heat-blocking survival trick while in tun state
Tardigrades, also known as water bears or moss piglets, are tiny eight-legged animals that can survive in extreme environments, where humans and most other animals would die. This resistance to extreme conditions, including ...
Medical Xpress / Autoimmune disease linked to poor outcomes with myelodysplastic syndrome
Having a preexisting autoimmune disease is an independent risk factor for poor outcomes with myelodysplastic syndrome (MDS), according to a study published in the June issue of Clinical Immunology.
Medical Xpress / Light movement in pregnancy linked to lower risk of complications
Moving more and sitting less could lower the risk of adverse pregnancy outcomes, according to a new study published in the Journal of the American Medical Association.
Phys.org / 'Shoot for the moon?' Aim a bit lower, researchers say
How ambitious should you be? Folk wisdom offers conflicting advice: "Shoot for the moon," but also, "Don't let the perfect be the enemy of the good." A new study by researchers at the University of Wyoming, Stanford University ...
Phys.org / A hidden supermassive black hole may be lurking inside the Antennae galaxies
Astronomers may have uncovered a hidden supermassive black hole inside the famous Antennae galaxies NGC 4038/4039, a pair of colliding galaxies best known for their spectacular bursts of star formation. The paper outlining ...
Tech Xplore / AI and ultralow-energy lasers enable an ultrafast authentication system
The security of modern communications heavily relies on systems that can rapidly and reliably verify users and the devices they are using. This process, known as authentication, essentially entails confirming that users or ...
Phys.org / Diamond quantum sensor could reveal elusive altermagnets
For nearly a century, there were two known kinds of magnets. Ferromagnets are the classic magnets that attract metal and keep pictures stuck to the refrigerator. Antiferromagnets hide their magnetism at the atomic scale but ...
Phys.org / Topological states emerge in quantum Hall-superconductor devices with multiple channels
Topological phases are unusual states of matter that give rise to properties protected by a material's overall structure (i.e., "topology"), as opposed to microscopic details. These phases are of great interest for the development ...
