Phys.org / Entanglement swapping using sum-frequency generation between single photons demonstrated for first time
The National Institute of Information and Communications Technology (NICT) has successfully demonstrated entanglement swapping (one of the key quantum communication protocols) using sum-frequency generation (SFG) between ...
Phys.org / Sounds modify visual perception: New links between hearing and vision in the rodent brain
Sounds can alter the way the brain interprets what it sees. This is the key finding of a new study by SISSA researchers in Trieste, published in PLOS Computational Biology. The research shows that, when sounds are paired ...
Phys.org / Physicists observe key evidence of unconventional superconductivity in magic-angle graphene
Superconductors are like the express trains in a metro system. Any electricity that "boards" a superconducting material can zip through it without stopping and losing energy along the way. As such, superconductors are extremely ...
Phys.org / 'Hidden' binding pocket in nuclear receptors offers alternative drug targets
A study from St. Jude Children's Research Hospital uncovered an alternative binding pocket within nuclear receptors, revealing a much-needed new therapy route for this important class of drug targets. The scientists found ...
Phys.org / Compact laser system shows 80% efficiency for ultrashort light pulses is possible
Lasers that emit extremely short light pulses are highly precise and are used in manufacturing, medical applications, and research. The problem: efficient short-pulse lasers require a lot of space and are expensive.
Phys.org / Digital map increases Roman Empire road network by 100,000 kilometers
A new high resolution digital dataset and map—named Itiner-e—of roads throughout the Roman Empire around the year 150 CE is presented in research published in Scientific Data. The findings increase the known length of ...
Phys.org / Growing transgenic plants in weeks instead of months by hijacking a plant's natural regeneration abilities
Plant biologists have developed a method for growing transgenic and gene-edited plants that cuts the slow and expensive process down from months to weeks.
Phys.org / Northern lights may be visible in parts of the US due to solar storms
Solar storms may bring colorful auroras to several northern U.S. states Thursday night.
Phys.org / Not-so-model behavior: Popular software tools may give faulty forecasts
Some of the models used to forecast everything from financial trends to animal populations in an ecosystem are incorrect, according to an Idaho State University statistician.
Phys.org / A genetic switch lets plants accept nitrogen-fixing bacteria
Researchers are one step closer to understanding how some plants survive without nitrogen. Their work could eventually reduce the need for artificial fertilizer in crops such as wheat, maize, or rice.
Phys.org / Space dust reveals Arctic ice conditions before satellite imaging
Arctic sea ice has declined by more than 42% since 1979, when regular satellite monitoring began. As the ice grows thinner and recedes, more water is exposed to sunlight. Ice reflects sunlight but dark water absorbs it, advancing ...
Phys.org / The enzyme that doesn't act like one: NUDT5 controls DNA building block production through structure, not catalysis
Inside every cell, a finely tuned metabolic network determines when to build, recycle, or stop producing essential molecules. A central part of this network is folate metabolism, a process that provides vital chemical units ...
