Phys.org / How quasars shut down star formation in the early universe
Supermassive black holes lurk at the centers of massive galaxies, including our own Milky Way. Puzzlingly, supermassive black holes more than a billion times the mass of the sun appear to exist just a few hundred million ...
Medical Xpress / Artery widening, not blockages, linked to common stroke
Scientists have uncovered new evidence that challenges long-held assumptions about the causes of a common type of stroke, offering clues as to why widely used treatments may not work. The study found that the buildup of fatty ...
Tech Xplore / Water-splitting catalyst unlocks cheaper hydrogen at significantly lower temperatures
University of Birmingham research published today has shown a new low-temperature method for producing hydrogen that is suitable for both centralized hydrogen production, and also local generation using waste heat from large-scale ...
Phys.org / Space junk falls to Earth faster when sunspots peak, reshaping satellite collision forecasts
Solar emissions exert 'drag' on space junk orbiting Earth. From historical measurements across a period of 36 years, researchers have now shown that space junk begins to fall down much faster once the sun's activity across ...
Phys.org / Polar vortex forecasts gain months of lead time with new climate-based method
Florida State University researchers have discovered how to accurately predict winter weather forecasts months in advance, affording sectors such as agriculture, water management, energy use and public health a longer lead ...
Medical Xpress / New survey finds that majority of Americans are concerned about high blood pressure, the 'silent killer'
A new survey by Morning Consult and the nonprofit Physicians Committee for Responsible Medicine finds that a majority of Americans, 60%, are concerned about high blood pressure. Nearly half of Americans have high blood pressure ...
Phys.org / How evolution sculpts the facial shapes of birds and mammals
Shapes of beaks and snouts come in an extraordinary range of forms, reflecting adaptations to different lifestyles and environments. Yet beneath this diversity lies a paradox: across birds and mammals, faces are built using ...
Phys.org / Death-defying protein found in tardigrades preserves synthetic cells
A protein found only in microscopic tardigrades, one that allows them to survive extreme conditions like dehydration, can convey similar durability in synthetic cells, according to new research from University of Michigan ...
Phys.org / Inexpensive material compresses light, paving the way for photonic microcircuits in the terahertz range
A two-dimensional lamellar crystal composed of atomically thin layers of lead iodide (PbI2) could be used to manufacture a new generation of circuits that use light and mechanical vibrations (rather than electrons) to transmit ...
Tech Xplore / Cooling without pumps: New measurement data for modular reactors
Passive cooling systems for nuclear power plants operate without pumps or electricity: They rely solely on physical effects such as density differences to dissipate heat. Researchers at the Paul Scherrer Institute PSI have ...
Medical Xpress / Testosterone suppresses brain tumor growth in males, study suggests
In a new study, scientists at Cleveland Clinic discovered that hormones associated with male development may play a key role in limiting the growth of brain tumors in men. The research team found that the loss of androgen ...
Phys.org / Hourglass nanographenes unlock strong, robust multi-spin entanglement
Researchers from the National University of Singapore (NUS) and collaborators have developed a predictive design strategy for creating graphene-like molecules with multiple interacting spins and enhanced resilience to magnetic ...
