Phys.org / Detailed DNA repair snapshots reveal how BRCA-linked cancer cells may survive
Scientists have captured the most detailed structural images to date of a specific type of protein's DNA repair process, a finding that could reveal ways to inhibit the effects of BRCA1 and BRCA2 mutations that heighten the ...
Phys.org / Atomic map reveals how Leptospira bacteria flip virulence switch inside hosts
During infection, pathogens must adapt quickly to the conditions to thrive inside the body. A research team at the University of Basel, Switzerland, has uncovered how a key protein switches on the machinery that enables Leptospira ...
Phys.org / Small differences in cell structures called microtubules determine how well cancer drug performs
A research team from the School of Biomedical Sciences at the LKS Faculty of Medicine, the University of Hong Kong (HKUMed), has uncovered the mechanism underlying how cancer patients respond to a widely used cancer drug, ...
Phys.org / Self-powered fibers can spot oil contamination and heat buildup within milliseconds
Oil spills and fires are two very different hazards, but both can cause major damage before people have time to react. Oil contamination can spread quickly across water and harm marine ecosystems, while undetected heat buildup ...
Phys.org / New self-assembling polymers proven to be effective at gene delivery
A collaboration of scientists at the University of Manchester and the University of Birmingham has explored a more effective and less toxic way of delivering genetic material into cells, a challenge central to areas such ...
Phys.org / Improving animal welfare in the lab: AI helps better detect pain
At first glance, the white plastic box with a bright orange floor looks like something for storing children's toys. However, the box isn't used to store Lego bricks; it contains real mice—with the aim of minimizing their ...
Phys.org / More than two species? Scientists challenge taxonomy of two-toed sloths in Amazonia
A new study by scientists from the Leibniz Institute for Zoo and Wildlife Research (Leibniz-IZW) has revealed significant cryptic diversity within two-toed sloths (Choloepus) in Amazonia, challenging the long-established ...
Phys.org / How bacteria circumvent plants' immune system
How are bacterial pathogens able to effectively overcome plants' defense mechanisms? Researchers working with Professor Şuayb Üstün at Ruhr University Bochum, Germany, have found a surprising answer to this question: The ...
Phys.org / Rare ribosome tweak in E. coli reveals possible antibiotic target
Storing genetic material as DNA or RNA is all well and good for life on Earth, but it would be entirely pointless if we couldn't do anything with it. To use our genetic blueprints, all organisms need to translate the message ...
Phys.org / Universal patterns emerge across 22 languages, mapping how vocabularies evolve
Human languages are known to have grown and changed considerably over the course of history, often reflecting technological, cultural, and societal shifts. Studying the evolution of languages can thus offer valuable insight ...
Phys.org / Deep under Antarctic ice, a long-predicted cosmic whisper finally breaks through in 13 strange bursts
A detector buried deep in Antarctic ice has captured the first experimental evidence of a predicted but never-before-seen phenomenon: radio pulses generated when high-energy cosmic rays slam into the ice sheet and trigger ...
Phys.org / Why did Clovis toolmakers choose difficult quartz crystal? New study offers clues
Quartz crystals are difficult to knap due to size, hardness, and crystalline structure, making them a "low-quality" raw material. However, the Clovis people of North America sometimes made points and other tools from this ...
