Phys.org / Light-activated compound kills antibiotic-resistant bacteria by turning its own defense enzyme against it
Antibiotic resistance is becoming an accelerating crisis because of the overuse and misuse of antibiotics over many years. The problem is exacerbated when antibiotics wipe out susceptible bacteria but leave resistant bacteria ...
Phys.org / Giraffes combine quantities similarly to addition
In addition to humans, some species of primates and birds have demonstrated under experimental conditions their ability to manipulate quantities in tasks that require combining or separating them, in a manner similar to addition ...
Phys.org / Unexpected pathway turns water and CO₂ into climate‑neutral methane on nickel–zirconia
Natural gas still plays an important role in many industrial sectors, but it is a climate-damaging fossil fuel. TU Wien and the University of Innsbruck have now discovered an unexpected reaction pathway that makes it possible ...
Phys.org / Giant exoplanet may hold a magnetic grip on its host star
Within their planetary systems, stars are continuously shaping their orbiting planets through gravity, radiation and magnetic forces. So far, this relationship has appeared to be a one-way street.
Phys.org / Why nanoscale droplets don't coalesce and microscale droplets do
Olive oil and water do not naturally mix. Water molecules are polar, having a net electric dipole moment due to the bend angle of about 104.5° between the two oxygen-hydrogen bonds. Olive oil is nonpolar due to its long hydrocarbon ...
Phys.org / Mummified dogs reveal Tiwanaku people buried companions beside homes long before they became status symbols
In the arid landscapes of southern Peru, around 1,100 years ago, someone carefully dug a small pit, laid down a woven mat and placed a young dog within as if sleeping, possibly wrapped in twine. Centuries later, the mummified ...
Phys.org / First-of-a-kind laser spring opens up new avenues for plasma control
When a high-intensity laser interacts with plasma, the charged particles typically oscillate back and forth like waves on the ocean. But what if the laser itself could twist like a whirlpool? Researchers have now demonstrated ...
Phys.org / New superconductors identified, unlocking process that could yield thousands more
An international team of quantum researchers has shown how machine learning can be used to filter a practically infinite number of possible material combinations to identify candidates for superconductivity. Thanks to the ...
Phys.org / Some boreal forest species fail to recover even 100 years after clearcutting
Boreal forests are being clear-cut faster than some of their wildlife and plant species can recover, with a few failing to return even 100 years after harvesting, according to University of Alberta-led research.
Phys.org / Graphene can hold multiple states of superconductivity, a new study finds
The ordinary graphite in pencil lead is proving to be surprisingly multifaceted at the microscale. In a study published in the journal Nature, MIT researchers report that a certain microscopic structure found in natural graphite ...
Phys.org / Plutonium compound unlocks rare topological quantum behavior with potential nuclear science applications
Plutonium is one of the most complex elements in the periodic table. First synthesized and isolated in 1940 by scientists at the University of California, Berkeley, plutonium has been studied closely for more than eight decades. ...
Phys.org / First ever dinosaur found in Antarctica described for science
The first dinosaur fossil found on the Antarctic continent has been described scientifically. The fossil, a vertebra, was found on a British Antarctic Survey (BAS) expedition in 1985 but has only recently been recognized ...
