Phys.org / New technology reveals hidden DNA scaffolding built before life 'switches on'
For decades, scientists viewed the genome of a newly fertilized egg as a structural "blank slate"—a disordered tangle of DNA waiting for the embryo to wake up and start reading its own genetic instructions. In research ...
Phys.org / Atom-thin electronics withstand space radiation, potentially surviving for centuries in orbit
Atom-thick layers of molybdenum disulfide are ideally suited for radiation-resistant spacecraft electronics, researchers in China have confirmed. In a study published in Nature, Peng Zhou and colleagues at Fudan University ...
Phys.org / Ultrasound-activated molecules show potential for killing antibiotic-resistant bacteria
Researchers from the Indian Institute of Technology Gandhinagar (IITGN) have recently demonstrated the feasibility of using estrone-linked BODIPYs sonosensitizers for antimicrobial sonodynamic therapy (SDT). Their initial ...
Phys.org / Mate choice: How social trends influence mate diversity
Whether people follow a general trend when choosing a partner or consciously decide against it has a noticeable impact on the diversity of phenotypes to choose from. This is shown by a new study by the University of Würzburg.
Phys.org / Shorter early-life telomere length could predict survival in Arctic seabirds
A study published in Ecological and Evolutionary Physiology reveals a surprising link between cellular aging markers and survival in black-legged kittiwakes (members of the gull family). In the work titled "Who's coming home? ...
Medical Xpress / Centenarians' blood sheds light on the mechanisms of longevity
In Switzerland, 0.02% of the population lives beyond the age of 100. Could there be biological characteristics associated with this exceptional longevity? As part of the "SWISS100" study, the first large-scale Swiss research ...
Phys.org / Fungi could transform leftovers into lifelines
As the global population climbs toward 10 billion and climate change strains farmland, scientists are searching for new ways to feed the world. A group of Cornell food science researchers say one answer may lie not in fields ...
Tech Xplore / Borrowing from biology to power next-gen data storage
DNA, the genetic blueprints in every living organism, is nature's most efficient storage mechanism, capable of storing about 215 million gigabytes of data per gram. That storage capacity, if applied to electronics, could ...
Phys.org / Ice Age erosion may explain Appalachians' smoother northern peaks
Hike north on the Appalachian Trail and the scenery slowly transforms. Rugged, steep ridgelines in Tennessee and Virginia soften into the broad summits and smooth peaks of Pennsylvania and New Jersey. According to new research ...
Medical Xpress / Two lipids that help switch on STING open doors in fight against autoimmune disorders and cancer
UT Southwestern Medical Center researchers have identified two lipids that work together with a quintessential protein known as stimulator of interferon genes (STING) to launch an immune response in the human body. Their ...
Tech Xplore / 'Probably' doesn't mean the same thing to your AI as it does to you
When a human says an event is "probable" or "likely," people generally have a shared, if fuzzy, understanding of what that means. But when an AI chatbot like ChatGPT uses the same word, it's not assessing the odds the way ...
Medical Xpress / Why our immune system remembers vaccinations for decades
Why can the human immune system often remember a vaccination for a whole lifetime? Researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) and Universitätsklinikum Erlangen have now investigated this question. ...
