Phys.org / Structural blueprint for RNA therapeutics reveals why some siRNA molecules work better than others
RNA interference is a natural mechanism for living cells to control whether specific genes are being used. Crowned with the 2006 Nobel Prize in Physiology or Medicine, the discovery of RNA interference has since been harnessed ...
Phys.org / Uncovering the trigger behind slow earthquakes
New research led by the University of New England's Dr. Timothy Chapman has uncovered the trigger behind slow earthquakes, providing valuable answers for those living in disaster-prone areas. The research has been published ...
Phys.org / Synthetic chemical framework can switch magnetic spin states at near ambient temperatures
There is growing demand for smart materials that can change their physical properties in response to various external stimuli such as light, heat, pressure, magnetic fields and electric fields. One such physical property ...
Phys.org / Tiny DNA 'hitchhikers' may be reshaping life in thawing Arctic soils
Amid the peatlands of northern Sweden, billions of microbes are quietly rewriting their genetic playbooks—and doing so far more often than scientists realized.
Phys.org / Switching spin states in manganese ions with light opens new path for molecular memory
Researchers at Johannes Gutenberg University Mainz (JGU) have developed a new way to use molecules as tiny data storage devices with a new manganese-based material. Until now, this was possible only with iron-containing molecular ...
Phys.org / Reanalysis suggests 'Phoebe' is a variable star, not a primordial black hole
A new study debunks a recent claim that astronomers may have detected a lunar-mass primordial black hole. In a reanalysis of observations from the Dark Energy Camera (DECam), researchers found that the star nicknamed "Phoebe" ...
Phys.org / Shining blue light on gold-graphene nanodots achieves wound healing trifecta
Closing wounds, burns and deep cuts isn't enough to kick-start healing. A wound needs a clean environment, free of bacterial infection and interruption. That calls for three components working together—one to kill bacteria, ...
Phys.org / Lost megalodon vertebrae resurface, confirming 80-foot size estimate
An associated set of gigantic vertebrae belonging to the iconic extinct megalodon, or megatooth shark, that had been missing in action since the 1980s was discovered, providing new information about the shark's lifestyle. ...
Phys.org / Off-center stellar death points to wandering supermassive black hole stripped of its own galaxy
Astronomers have uncovered new details about the black hole that ripped apart a star in a tidal disruption event named AT2024tvd. Findings suggest it is a wandering supermassive black hole—the kind that is not located at ...
Phys.org / Injectable silk-kudzu hydrogel achieves complete wound closure in laboratory tests
Researchers at the Terasaki Institute for Biomedical Innovation have developed an injectable hydrogel, a water-based gel material, made from silk proteins and a plant-derived compound. In laboratory tests, the material promoted ...
Phys.org / NASA races to save Swift telescope from falling back to Earth with daring rescue mission
NASA is racing to save an aging telescope from falling back to Earth with a daring rescue mission.
Phys.org / Human activity has driven retreat of Antarctica's fastest melting glacier
Human-driven climate change significantly intensified the retreat of one of the most important glaciers in Antarctica during the 20th century. The Pine Island Glacier, which drains a large part of the West Antarctic Ice Sheet ...
