Researchers in The University of Texas at El Paso's Department of Chemistry and Biochemistry have developed a nanohybrid vehicle that can be used to optimally deliver drugs into the human...
Air Force awards $258.7M to Dataminr for push alerts system
The Air Force has awarded Dataminr with a five-year, $258.7 million contract to develop a system of push alerts, the Pentagon announced Thursday.
New design could make fiber communications more energy efficient
Researchers say a new discovery for optoelectronic devices could help make optical fiber communications more energy efficient.
In glowing colors: Seeing the spread of drug particles in a forensic lab
Scientists used UV light and glow powder to study the way small amounts of drug residue get spread around a forensic chemistry lab when analysts test seized drugs. Their study...
Inexpensive, portable detector identifies pathogens in minutes
Researchers have demonstrated an inexpensive yet sensitive smartphone-based testing device for viral and bacterial pathogens that takes about 30 minutes to complete. The roughly $50 smartphone accessory could reduce the...
Scientists fashion new class of X-ray detector
Scientists have identified a new class of X-ray detectors based on layered perovskites, a semiconducting material.
Researchers are making recombinant-protein drugs cheaper
The mammalian cell lines that are engineered to produce high-value recombinant-protein drugs also produce unwanted proteins that push up the overall cost to manufacture these drugs. These same proteins can...

Watch Fountains of Wayne honor fallen bandmate Adam Schlesinger, who died from COVID-19
Members of Fountains of Wayne perform together for the first time in seven years, with help from Sharon Van Etten, to salute bandmate Adam Schlesinger, who died from COVID-19.
Ultrafast vector imaging of plasmonic skyrmion dynamics with deep subwavelength resolution
Plasmonic skyrmions are an optical manifestation of topological defects in a continuous vector field. Identifying them requires characterization of the vector structure of the electromagnetic near field on thin metal...
Determination of the melanocortin-4 receptor structure identifies Ca2+ as a cofactor for ligand binding
The melanocortin-4 receptor (MC4R) is involved in energy homeostasis and is an important drug target for syndromic obesity. We report the structure of the antagonist SHU9119-bound human MC4R at 2.8-angstrom...
Reducing the carbon footprint of artificial intelligence
Artificial intelligence has become a focus of certain ethical concerns, but it also has some major sustainability issues. Last June, researchers at the University of Massachusetts at Amherst released a startling report estimating...

Watch: Chris Hemsworth shows off his Thor hammers on 'Kimmel'
Chris Hemsworth appeared on Jimmy Kimmel Live and displayed two of his Thor hammers that he used on various Marvel films.
A new way to cool down electronic devices, recover waste heat
Using electronic devices for too long can cause them to overheat, which might slow them down, damage their components or even make them explode or catch fire. Now, researchers have...
Professor collaborates with international colleagues on shell evolution of exotic nuclei research
In an atomic nucleus, protons and neutrons, collectively called nucleons, are bound together by nuclear forces. These forces describe the interactions between nucleons, which cause them to occupy states grouped...
Wiring the quantum computer of the future: A novel simple build with existing technology
Efficient quantum computing is expected to enable advancements that are impossible with classical computers. Scientists from Japan and Sydney have collaborated and proposed a novel two-dimensional design that can be...
