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 / Novel AI platform accelerates discovery of chemical catalysts for industry
CatDRX is a generative AI framework developed at Institute of Science Tokyo, which enables the design of new chemical catalysts based on the specific chemical reactions in which they are used. The model learns from large ...
Phys.org / GoMars model simulates 50-year Martian dust cycle
Mars is a dusty planet dominated by vast, dry deserts, with no easily accessible sources of liquid water. Much like on Earth, dust is lifted from Mars's surface by wind and rotating air columns, transported through the atmosphere, ...
Phys.org / New fossil lungfish from Yunnan sheds light on critical stage of early vertebrate evolution
A research team led by Prof. Zhu Min—a member of the Chinese Academy of Sciences (CAS) and affiliated with the CAS Institute of Vertebrate Paleontology and Paleoanthropology (IVPP)—has identified a new species of fossil ...
Phys.org / 3D analysis of wrist ligaments reveals locomotion clues in human ancestors
When studying how fossil hominids moved, researchers usually analyze the morphology of bones—which is crucial for understanding the evolution of bipedalism—focusing mainly on muscle insertion sites. However, the potential ...
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 / 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 / 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 / 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 / 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 ...
