Phys.org / New theory on how six‑tonne Stonehenge rock was transported from Scotland thousands of years ago: On a glacier
Built from stones weighing between 2 and 25 tonnes (2 to 28 tons), the structure of Stonehenge demonstrates a scale of construction hard to imagine before the invention of the wheel. The mystery deepens when you consider ...
Phys.org / New Ribo-Tweezer tool can pluck individual protein pieces out of a working ribosome
Every human cell has millions of ribosomes that make proteins. For decades, biologists thought of ribosomes as tiny, uniform machines. But now a Stanford Medicine team is showing that ribosomes are much more interesting and ...
Phys.org / 'Bag of Bones' preserves rare three-tier prehistoric meal in Outback Queensland
An ancient marine 'crime scene' discovered near Richmond captures the world first evidence of a flying reptile being eaten by a sea monster… before that predator became dinner itself.
Phys.org / New research shows how 'hot electrons' can reshape metals in billionths of a second
Researchers at The University of Manchester have revealed how intense electronic excitation can trigger rapid structural changes in metals—without heating the atomic lattice—offering new insight into ultrafast materials behavior.
Phys.org / Deformed head shapes in fossilized humans show their infants were probably just as helpless as modern human babies
Archaic human parents had to look after helpless infants like modern-day parents do, according to new research. Human babies are born less developed than those of other great apes and are therefore unable to move as freely. ...
Phys.org / Mesolithic hunter-gatherers on Malta relied on repeated sea crossings, study suggests
The existence of humans on Malta, a tiny Mediterranean island, during the Mesolithic period is puzzling. Archaeological evidence indicates that foragers occupied the Maltese islands between 8,500 and 7,500 years ago, and ...
Phys.org / Single molecule becomes quantum sensor for imaging proteins at nanoscale
A new quantum sensing technique could enable measurements of single protein structures and other important molecules, with potential applications in drug discovery and structural biology. A research team from the Institute ...
Phys.org / 100% organic free-range egg production could have negative consequences for climate and nature
A study published in Royal Society Open Science reveals striking trade-offs when it comes to different methods of egg production. Using UK data, the study compared several possible scenarios for the egg industry, including ...
Phys.org / Algal blooms accelerate plastic weathering, potentially fueling microplastic formation
Every summer, algal blooms turn rivers and lakes green. Although they are widely known as a major form of water pollution that makes water murky, a KAIST research team has now shown for the first time that algal bloom conditions ...
Phys.org / Ultracold neutrons don't disappear into the mirror world
For decades, a theory in physics has postulated the existence of a mirror world whose interaction with our own reality is extremely feeble. The particles in this mirror universe are also thought to be candidates for dark ...
Phys.org / Diets high in a particular type of fat help protect bees against pesticides
Diets rich in polyunsaturated fatty acids—a type of fat that supports brain function, cell growth and heart health—may help protect honey bees against the toxic effects of pesticides, according to a study led by researchers ...
Phys.org / More evidence Mars once had water emerges from old Spirit rover data
More than 20 years after NASA's Spirit rover landed on Mars, a researcher from Edith Cowan University (ECU) has uncovered new evidence that suggests water may once have covered large parts of the red planet.
