Phys.org / First-time use of AI for genetic circuit design demonstrated in a human cell line
There are hundreds of cell types in the human body, each with a specific role spelled out in their DNA. In theory, all it takes for cells to behave in desired ways—for example, getting them to produce a therapeutic molecule ...
Phys.org / Signs of ancient life turn up in an unexpected place
Dr. Rowan Martindale, a paleoecologist and geobiologist at the University of Texas at Austin, was walking through the Dadès Valley in the Central High Atlas Mountains of Morocco when she saw something that literally stopped ...
Phys.org / A 'cosmic clock' in tiny crystals reveals the rise and fall of Australia's ancient landscapes
Australia's iconic red landscapes have been home to Aboriginal culture and recorded in songlines for tens of thousands of years. But further clues to just how ancient this landscape is come from far beyond Earth: cosmic rays ...
Phys.org / Frozen hydrogen cyanide 'cobwebs' offer clues to origin of life
A substance poisonous to humans—hydrogen cyanide—may have helped create the seeds of life on Earth. At cold temperatures, hydrogen cyanide forms crystals. And, according to computer models reported in ACS Central Science, ...
Phys.org / Do even low-mass dwarf galaxies merge? New clues from the outer stars of a Milky Way satellite
Using the Subaru Telescope's wide-field camera, astronomers have discovered a previously unknown structure surrounding a tiny satellite galaxy of the Milky Way. The newly discovered structure exhibits features resembling ...
Phys.org / Atomic-level surface control boosts brightness of eco-friendly nanosemiconductors by 18-fold
Light-emitting semiconductors are used throughout everyday life in TVs, smartphones, and lighting. However, many technical barriers remain in developing environmentally friendly semiconductor materials.
Phys.org / Tiny RNA molecules in sperm can have big impact on health of babies
Mounting evidence from research on nematodes to mice indicate that a father's environment, such as what he eats or if he is exposed to stress or toxicants, can lead to metabolic and behavioral disorders in his offspring.
Medical Xpress / Increased levels of Alzheimer's-linked protein found in some with long COVID
A study of 227 individuals who experienced neurocognitive difficulties post COVID-19 infection—such as headaches, vertigo, balance dysregulation, changes in taste/smell, and brain fog—displayed a significant increase ...
Phys.org / Type Ia supernova delayed-detonation model supported by SN 2024gy observations
A research team from the Yunnan Observatories of the Chinese Academy of Sciences (CAS), in collaboration with domestic and international partners, has carried out observational studies on SN 2024gy—a high-velocity Type ...
Phys.org / Scientists reveal what drives homosexual behavior in primates
Homosexual behavior in primates has a deep evolutionary basis and is more likely to occur in species that live in harsh environments, are hunted by predators or live in more complex societies, scientists said Monday.
Phys.org / Ancient Tethys Ocean shaped Central Asia's landscape, study suggests
New research from Adelaide University suggests the power of the ancient Tethys Ocean might have shaped Central Asia's topography during the Cretaceous period.
Medical Xpress / Can biology reveal parental manipulation?
Parental alienation is when one parent manipulates the child into distancing themselves from the other parent. But does this leave detectable biological evidence?
