Phys.org / How an influx of salt may affect microbial ecosystems in rivers, estuaries and coastal waters worldwide
As sea levels rise due to climate change, encroaching seawater will likely make freshwater environments saltier. In a new study, MIT researchers have shown how that increase in salinity might affect microbial ecosystems found ...
Phys.org / How human activities compromise coral health and resilience
Human activities are fundamentally altering the chemical makeup of coral reefs, according to a study led by the University of Hawai'i at Mānoa and published in Nature Communications. The research team discovered that 25 contaminants ...
Phys.org / Bones reveal ancient Egyptian princesses born 4,000 years ago used weapons
For decades, scientists have disputed the meaning of the weapons found in the burial chambers of some ancient Egyptian princesses. Were they symbolic or practical tools? Now, a reassessment of five royal women's mummies from ...
Phys.org / In search of life beyond our solar system: Atmosphere detected on a habitable-zone rocky world
In a major milestone in the search for life on other planets, astronomers have detected, for the first time, an atmosphere surrounding an Earth-like, rocky planet orbiting within the habitable zone of another star. The finding ...
Phys.org / A new record holder for the world's oldest amber discovered in China
Paleontologists in China have discovered the oldest chemically verified amber ever found, dating to 385 million years ago. That's approximately 140 million years before dinosaurs roamed Earth. The previous record holder was ...
Phys.org / Brain-inspired nanopore device uses current-induced heating for memory operations
Some researchers are leaning into biology for inspiration in computing. In particular, neuromorphic computing offers a brain-inspired approach to hardware that replaces traditional binary processing with systems that function ...
Phys.org / Quantum teleportation could reduce photon loss in long-distance communications
Quantum technologies, which leverage the principles of quantum mechanics, have been found to outperform their classical counterparts on specific tasks. Among other things, past studies have highlighted the potential of quantum ...
Phys.org / Nearby rocky planet may be replenishing helium from atmosphere, study finds
Nearly a decade after the discovery of LHS 1140b, a rocky exoplanet in the habitable zone of a nearby low-mass star, a new study reveals that the object may have its own atmosphere.
Phys.org / Scientists invent new board games to reveal how we tackle the unknown
Playing board games can be fun, challenging, infuriating and a great way to pass the time. They can also help scientists understand how we solve new problems.
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 ...
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 / Single fission experiment maps excess gamma rays from more than a dozen unstable nuclei
In a single experiment, physicists have measured the "excess" emission of high-energy gamma rays from more than a dozen heavy, unstable atomic nuclei. Mapping the gamma-ray emissions of so many isotopes produced in nuclear ...
