Phys.org / New study maps where wheat, barley and rye grew before the first farmers found them
Using advanced machine learning and climate models, researchers have shown that the ancestors of crops like wheat, barley, and rye probably were much less widespread in the Middle East 12,000 years ago than previously believed. ...
Phys.org / What dating apps are really optimizing. Hint: It isn't love
In the weeks leading up to Valentine's Day, dating apps typically see a spike in new users and activity. More profiles are created, more messages sent, more swipes logged.
Phys.org / 'Virgin' frescoes emerge from Pompeii suburb
Amid the remains of a sumptuous villa near Pompeii, the hard-hatted conservationist scraped away centuries-old ash to reveal a vibrant red fresco.
Phys.org / 100 beavers set to be reintroduced to the UK this year, with more to come
Centuries after they were wiped out, the reintroduction of beavers to the UK is gathering pace. Following a government announcement allowing beavers to be released in the wild, a flurry of reintroductions are planned for ...
Phys.org / Basic research on Listeria bacteria leads to unique cancer therapy
After nearly 40 years of research on how Listeria bacteria manipulate our cells and battle our immune system to cause listeriosis, Daniel Portnoy and his colleagues have discovered a way to turn the bacteria into a potent ...
Phys.org / Gravitational lensing technique unveils supermassive black hole pairs
Supermassive black hole binaries form naturally when galaxies merge, but scientists have only confidently observed a very few of these systems that are widely separated. Black hole binaries that closely orbit each other have ...
Phys.org / A new microscope for the quantum age: Single nanoscale scan measures four key material properties
Physicists in Leiden have built a microscope that can measure no fewer than four key properties of a material in a single scan, all with nanoscale precision. The instrument can even examine complete quantum chips, accelerating ...
Phys.org / Cutting down on quantum-dot crosstalk: Precise measurements expose a new challenge
Devices that can confine individual electrons are potential building blocks for quantum information systems. But the electrons must be protected from external disturbances. RIKEN researchers have now shown how quantum information ...
Phys.org / The changing chemistry of invasive death cap mushrooms
The California Department of Public Health reported 39 related poisonings in the last three months, leading to the death of four people, at least three liver transplants, and many more people made sick. The culprit? In each ...
Phys.org / Photonic integrated circuits enable programmable non-Abelian 'braiding' of light states
A research team has successfully implemented a programmable spinor lattice on a photonic integrated circuit (PIC). This platform enables the realization of non-Abelian physics, in which the outcome of operations depends on ...
Phys.org / Silicon metasurfaces boost optical image processing with passive intensity-based filtering
Of the many feats achieved by artificial intelligence (AI), the ability to process images quickly and accurately has had an especially impressive impact on science and technology. Now, researchers in the McKelvey School of ...
Phys.org / Rich medieval Christians bought graves 'closer to God' despite leprosy stigma, archaeologists find
Medieval Christians in Denmark showed off their wealth in death by buying prestigious graves: the closer to the church, the higher the price. Researchers used these gravesites to investigate social exclusion based on illness, ...
