Science X / This device pulls electricity from humid air using waste materials
Imagine what would happen if the source of your electricity was not the sun, wind, or water flow, but rather the moisture present in the air? The ability of moisture to provide energy has been well-known for a long time, ...
Phys.org / Rare mutations are helping dangerous hospital bacteria slip past the last-line antibiotic defense
Another last-resort antibiotic has fallen victim to the rapid evolution of drug-resistant superbugs. The powerful antibiotic combination ceftazidime-avibactam (CZA), widely used to treat severe hospital-acquired infections ...
Medical Xpress / A step toward lab‑grown sperm: Scientists turn stem cells into early sperm cells in a mini‑testis
About 9% of men of reproductive age in the United States experience fertility problems. One of the many causes of male infertility is a failure in germline development, the process by which embryonic cells develop into sperm ...
Phys.org / Tunas and other ocean predators may have evolved more slowly than previous research predicted
Today, oceans host a large variety of fast, resilient marine predators, including tunas, mackerels and various other fish species. Many of these fish belong to a lineage known as Scombridae, whose members are characterized ...
Phys.org / Living alligators expose why juvenile fossils can fool classification methods
Fossil finds are exciting moments that sometimes introduce the world to an ancient mammal or dinosaur that existed millions of years ago. But a longstanding problem in paleontology is that fossils are often incomplete, and ...
Tech Xplore / New contact material improves efficiency and stability of perovskite solar cells
A newly developed material for the electron contact improves the efficiency of single perovskite solar cells and perovskite/silicon tandem solar cells. The new material is based on a carborane molecule. It offers several ...
Phys.org / Webb telescope discovers hidden planet in famous star system
Astronomers using NASA's James Webb Space Telescope have discovered a giant planet outside our solar system, called an exoplanet, hiding within one of the most intensely studied planetary systems in the Milky Way galaxy.
Phys.org / Air from Greenland snow shows industrialization's impact on atmospheric methane
An international team of researchers, including scientists from Utrecht University and the University of Maryland, has reconstructed the concentration of clumped isotopes of methane in air from the past for the first time. ...
Medical Xpress / Are you listening to me? Well, kinda… Research shows people can track more than one conversation at once
Ever wondered how some people seem able to keep up with the conversation they're having while also noticing what's being said across the room? New research suggests this ability isn't simply good hearing but may reflect the ...
Tech Xplore / New spinning drone hides in plain sight: 'Phantom Twist' harnesses motion blur to nearly vanish in flight
By exploiting the quirks of human vision, Northwestern University engineers have designed a drone that nearly disappears before the eyes. For years, researchers have tried to design invisible drones and robots using camouflage, ...
Medical Xpress / Immune receptor plays dual role in promoting T-cell exhaustion in cancer
A new Northwestern Medicine study has uncovered how a key immunoregulatory receptor plays an unexpected dual role in promoting T-cell exhaustion during chronic infection and cancer, according to findings published in the ...
Tech Xplore / Engineers shrink powerful terahertz systems onto a single semiconductor chip
High-frequency waves classified as terahertz occupy a relatively underused region of the electromagnetic spectrum between infrared light and microwaves. Researchers have long recognized their unique potential for applications ...
