The well-developed sinus system in the now extinct cave bear (top left) is associated with uneven mechanical stress distributions in biting simulations (bottom left) conducted at UB. The much less developed sinus system in living bears, for example the sun or honey bear, (top right) allows mechanical stress to distribute evenly over the forehead region,…

The breakthrough by the researchers revealed that a symmetry that exists within the core of the…

NASA's Wide-field Infrared Survey Explorer (WISE) gifted us this ethereal view of the Pleiades. NASA/JPL-Caltech/UCLA Looking up into the great, star-studded expanse of the night sky doesn't have to make you feel small. On the evening of April 3, Venus will appear to be inside the Pleiades star cluster, a celestial sight that occurs every eight…

LOWELL, Mass. – A discovery by a team of researchers led by UMass Lowell nuclear physicists could change how atoms are understood by scientists and help explain extreme phenomena in outer space. The breakthrough by the researchers revealed that a symmetry that exists within the core of atoms is not as fundamental as scientists have believed.…

The NASA mission will identify planets with large orbits, similar to our solar system's far-flung giants, Uranus and Neptune. NASA's Wide Field Infrared Survey Telescope (WFIRST) will search for planets outside our solar system toward the center of our Milky Way galaxy, where most stars are. Studying the properties of exoplanet worlds will help us…

Heat from radioactivity, not starlight, could warm planets enough to allow liquid water to exist on their surfaces. Дмитрий Ларичев/iStock.com By Katherine KorneiApr. 1, 2020 , 11:15 AM Not too close, but not too far. That’s long been the rule describing how distant a planet should be from its star in order to sustain life.…

This schematic diagram maps out the binding energy (or superconducting energy gap) of individual electrons in a copper-oxide (cuprate) superconductor as measured by a sensitive microscope scanning across the surface. The size of the blue and yellow blobs surrounding individual atoms (red rods with arrowheads indicating their spin orientations) indicates the size of the energy…

AbstractThe spread of protein aggregates during disease progression is a common theme underlying many neurodegenerative diseases. The microtubule-associated protein tau has a central role in the pathogenesis of several forms of dementia known as tauopathies—including Alzheimer’s disease, frontotemporal dementia and chronic traumatic encephalopathy1. Progression of these diseases is characterized by the sequential spread and deposition…

A key characteristic of many neurodegenerative diseases is the slow accumulation of misfolded protein deposits in the neurons of the brain. In particular, the accumulation and spread of a protein known as tau is a feature of several forms of dementia, ranging from the most common form, Alzheimer’s disease, to chronic traumatic encephalopathy, a dementia…

Artist's concept of medium-sized black hole gobbling up passing star ESA/Hubble, M. Kornmesser The Hubble Space Telescope has detected the best-ever candidate for an intermediate- mass black hole (IMBH) —- a medium-sized black hole some 50,000 times the mass of our Sun in the act of gobbling up a passing star. If this discovery holds, it…

A spider that resembles Vincent van Gogh's famous 'Starry Night' painting has been discovered in Australia.This male, named Maratus constellatus, is no more than four millimeters in length and was spotted in the Little Desert National Park.The colorful arachnid is one of seven new species of Peacock spiders, which are tiny, harmless creatures that are…

The primary mirror of NASA's James Webb Space Telescope is planned to be deployed only once more on Earth, before being packaged for delivery to South America. Credit: NASA/Chris Gunn In a recent test, NASA's James Webb Space Telescope fully deployed its primary mirror into the same configuration it will have when in space. As…
