Phys.org / Experimental evolution uncovers how bacteria develop drug resistance
The bacteria Acinetobacter baumannii (A. baumannii) is a haunting presence in many hospitals in the United States, where more than one in 100 patients are treated for A. baumannii infections. This species of bacteria is known ...
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 / Peering inside 3D chaotic microcavities with X-ray vision
In the world of optics, tiny structures called microcavities—often no wider than a human hair—play a crucial role in technologies ranging from lasers to sensors.
Phys.org / Gyromorphs combine liquid and crystal traits to enhance light-based computers
Researchers have been developing computers that deploy light (photons) rather than electricity to power storage and calculations. These light-based computers have the potential to be more energy efficient than traditional ...
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 / Textbook view of NMDA receptor calcium signals upended by new findings
Drugs that act on NMDA (N-methyl-D-aspartate) receptors, which are essential for learning, memory and moment-by-moment consciousness, are key for treating neuropsychiatric disorders. These drugs were developed based on the ...
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 / 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 / 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 / Simply turning up the heat could transform chemical manufacturing
Scientists have developed a simple, low-cost method to drive key chemical reactions, which could make large-scale drug manufacturing faster, more accessible and affordable.
Phys.org / Three nonlinear optical materials achieve sub-200-nm cutoff edges for advanced photonics
Nonlinear optical (NLO) materials play a vital role in modern photonic technology, driving advancements in applications such as laser frequency conversion, ultrafast optical switching, and quantum information processing. ...
