Phys.org / Young shark species more vulnerable to extinction, fossil record reveals
Whether a species has just freshly emerged, or it has been around for millions of years does not dictate its vulnerability. This has been the assumption of an old debate on whether species' age plays a role in extinction ...
Phys.org / Engineered proteins enable smartphone-based detection of specific DNA sequences
Imagine a container of tomatoes arriving at the container terminal in Aarhus. The papers state that the tomatoes are from Spain, but in reality, we have no way of knowing if that is true.
Phys.org / Drone-mounted lab monitors fertilizer runoff in real time
What if, instead of taking a water or soil sample to the lab, you could take the lab to the sample? That's what a team of researchers reporting in ACS Sensors did with a new nitrate-monitoring "lab-on-a-drone" system. The ...
Phys.org / Detailed cell map unlocks secrets of how reproductive organs form
New research has mapped the cell types that specialize to form reproductive organs in both sexes, identifying key genes and signals that drive this process. The findings offer important insights into conditions affecting ...
Phys.org / Chemists develop unique tool for studying RNA in live cells
An innovative three-color method for capturing images of mRNA inside live mammalian cells has been developed by UMass Amherst chemists. Because RNA is both incredibly important to human life and health and poorly understood, ...
Phys.org / Enzyme disables bacterial toxin by cleaving key chemical ring structure
A research team at Leibniz-HKI has described a new enzyme that renders the highly toxic molecule malleicyprol harmless. Malleicyprol is considered an important virulence factor of Burkholderia bacteria, which causes, among ...
Phys.org / Data bias reduces reliability of AI models predicting antimicrobial resistance
Experts are increasingly turning to machine learning to predict antibiotic resistance in pathogens. With its help, resistance mechanisms can be identified based on a pathogen's genetics. However, the results should be viewed ...
Phys.org / Low-temperature greenhouse gas conversion: Direct current reveals charge-driven mechanism
Catalytic dry reforming of methane (DRM) offers a promising strategy for the sustainable utilization of greenhouse gases, CH4 and CO2. However, its practical application has long been hampered by severe catalyst deactivation ...
Phys.org / How the ocean's most abundant bacteria diversify into ecologically distinct groups
A study led by the University of Hawaiʻi at Mānoa's Hawaiʻi Institute of Marine Biology (HIMB) has revealed critical new details about one of the ocean's most abundant life forms—SAR11 marine bacteria. Understanding ...
Phys.org / Possible 'superkilonova' exploded not once but twice
When the most massive stars reach the ends of their lives, they blow up in spectacular supernova explosions, which seed the universe with heavy elements such as carbon and iron. Another type of explosion—the kilonova—occurs ...
Phys.org / What's powering these mysterious, bright blue cosmic flashes? Astronomers find a clue
Among the more puzzling cosmic phenomena discovered over the past few decades are brief and very bright flashes of blue and ultraviolet light that gradually fade away, leaving behind faint X-ray and radio emissions. With ...
Phys.org / A universal law could explain how large trades change stock prices
Financial markets are often seen as chaotic and unpredictable. Every day, traders around the world buy shares and sell assets in a whirlwind of activity. It looks like a system of total randomness—but is it really?
