Phys.org / Rescue mission is called off for NASA's aging Swift space telescope
The mission to save NASA's sinking Swift Observatory was called off Wednesday, dooming the telescope to a fiery reentry later this year.
Phys.org / Quantum light engine links atom-photon thermodynamics to classical physics
What is heat, and what is useful work if a machine consists only of an atom and light particles? In modern quantum technologies, this kind of question connects thermodynamics with quantum physics. Researchers at the University ...
Phys.org / New measurements explain how silicon and diamond achieve extreme reversible stretching
A research team led by Yang Lu from the Department of Mechanical Engineering at the Faculty of Engineering, The University of Hong Kong (HKU), has uncovered the microscopic physical nature of ultralarge elasticity in covalent ...
Phys.org / Arctic shipping a daunting prospect in hotly contested region
With Gulf turmoil slashing Suez Canal traffic, shipping firms are tempted to try the Arctic for quicker trips between Europe and Asia—but commercial prospects are unlikely to match countries' strategic ambitions for the North ...
Phys.org / 'Hidden stars' suggest that distant galaxies are much more massive than they appear
Astronomers have discovered that the most massive galaxies in the early universe contain far more small stars than expected. As a result, these early galaxies were likely much more massive than initial measurements suggested. ...
Medical Xpress / Oral therapy protected mice from lethal radiation while sparing cancer treatment
Researchers at the Fralin Biomedical Research Institute at VTC have developed an experimental oral therapy that protected mice from otherwise harmful radiation exposure while preserving radiation's ability to destroy cancer ...
Phys.org / Could teaching assistants be an overlooked teacher pipeline? New research says yes
As school districts continue searching for ways to recruit and retain teachers, new research from UNC-Chapel Hill suggests one promising pipeline may already be in classrooms: teaching assistants.
Medical Xpress / Why you move—not just how often—could affect dementia risk
For years, scientists have known that regular physical activity can help lower the risk of dementia. But new USC research suggests that it's not only the amount but also the activity's context—for work or for leisure—that ...
Phys.org / Messy life-producing cellular process caught in action for first time
All living things have a fleet of tiny copy machines that turn instructions from DNA into RNA molecules responsible for helping build proteins that keep organisms alive. One of those nanoscale machines, called eukaryotic ...
Phys.org / New lipid nanoparticle delivers capped circular RNA for longer-lasting gene expression
Researchers at Nagoya University in Japan in collaboration with FUJIFILM have developed a novel way of delivering circular RNA (cirRNA) into cells, paving the way for longer-lasting mRNA-based therapeutics including cancer ...
Phys.org / 'Wall-to-wall' map of NYC trees could help cool cities worldwide
Researchers have created an interactive map identifying 1.8 million individual trees in New York City, using a new approach that could optimize the placement of trees for cooling in cities around the world.
Phys.org / A single asteroid impact may explain the appearance of Mars' moon Deimos
Deimos, the smaller and outermost of Mars' two moons, is roughly oval in shape and has a deep depression at its south pole. Unlike its heavily scarred sister moon, Phobos, Deimos is covered by a loose layer of dust and rubble—a ...
