A new photodetector design using platinum-infused diamond nanowires achieves record-breaking UV sensitivity and heat resistance. Diamond nanowires embedded with platinum nanoparticles could transform high-temperature solar-blind photodetection thanks to their impressive performance and stability.

A drug called lenacapavir, administered in two injections a year, offers protection from HIV comparable to daily pills. One looming question: Will it be affordable for lower resource countries?

Quantum states stabilized by laser light and X-rays hint at breakthroughs in optoelectronics and quantum memory.

Oxford scientists have simulated light interacting with “empty” space—a strange quantum effect that sounds like science fiction but is rooted in real physics.

The US Food and Drug Administration on Wednesday approved Gilead Sciences’ twice-yearly injection to prevent HIV – a move the company hailed as a major breakthrough in the fight against the sexually transmitted virus.

Drugs to prevent HIV transmission, known as pre-exposure prophylaxis or PrEP, have existed for more than a decade. But because they typically require taking a daily pill, they have yet to make a significant dent in global infections.

“This is a historic day in the decades-long fight against HIV,” Gilead chairman and chief executive Daniel O’Day said in a statement.

Researchers at the University of British Columbia say they have developed a new tool to detect common drink-spiking drugs.

They say they plan to test the device, known as Spikeless, in the hopes it will one day be used widely to combat drugs being added to drinks and to prevent sexual assaults.

The university said in a news release that the “seemingly ordinary stir stick” can detect drugs such as GHB and ketamine within 30 seconds, changing colour if a beverage is contaminated.

Sasha Santos, an anti-violence activist working with the researchers on the project, says the technology has the potential to be a game-changer, adding that other drug testing tools are marketed to customers in a problematic way.

An anti-violence activist says the invention, which can detect drugs within 30 seconds, aims to make the stir sticks ubiquitous in bars, clubs and pubs, so every single drink served comes with a safety test.

In a groundbreaking achievement, scientists have used advanced artificial intelligence (AI) to decode the contents of a 2,000-year-old Greek scroll without ever unrolling it, unveiling new insights into ancient intellectual life.

Scientists have developed a non-toxic alternative to harmful PFAS chemicals using carbon and hydrogen-based compounds, offering a safer solution for products that currently rely on fluorine. An international team of scientists has developed a safer alternative to PFAS (perfluoroalkyl substances).

The findings indicate that this amino acid did not show a longitudinal decline with age. Taurine, a popular amino acid known for its role in energy drinks and supplements, may not be the aging breakthrough some hoped for. In a new study, scientists at the National Institutes of Health (NIH) have di

A research team led by Prof. Chang Hong from the National Time Service Center (NTSC) of the Chinese Academy of Sciences (CAS) has developed a strontium optical lattice clock with both frequency stability and systematic uncertainty surpassing 2×10^-18. This achievement places China among the global leaders in the field of optical lattice clock development.

The breakthrough aligns with the roadmap set by the 27th General Conference on Weights and Measures (CGPM) in 2022, which proposed redefining the SI unit of time—the second—by 2030. The resolution outlined rigorous performance benchmarks for next-generation optical clocks.

Strontium optical lattice clocks, known for their exceptional precision, have emerged as the most promising candidates for the redefinition, offering systematic uncertainties two orders of magnitude lower than those of the current cesium fountain clocks.
