Phys.org / Cells have a secret power line: How the nucleus gets its own private energy supply from mitochondria
For decades, biologists assumed a cell's energy simply diffused to wherever it was needed. It turns out the most important destination of all has a private delivery line.
Phys.org / Fossil discovery shows the interaction between giant marine reptiles
Approximately 160 million years ago, during the Age of Dinosaurs, giant marine reptiles ruled the seas. One such creature, an ichthyosaur, swam in a sea near present-day Peterborough, England. This huge animal, shaped like ...
Phys.org / Ancient genome duplications laid the foundations of complex brains, research suggests
New findings, published in Nature, help answer the riddle of how vertebrates evolved the diverse array of brain cells that distinguishes them from other animals. It appears that a dramatic expansion of the genetic toolkit ...
Phys.org / Galaxy-killing wind discovered in the early universe
Astronomers have discovered a "galaxy-killing wind" that may explain why there are far more massive "dead" galaxies than expected in the early universe. This wind, powered by cosmic collisions between galaxies, could quickly ...
Phys.org / How Argonaute, a key protein for RNA therapeutics, becomes activated
RNA therapeutics have emerged as one of the most promising new classes of medicines. Eight small interfering RNA (siRNA) drugs have already been approved worldwide for the treatment of genetic diseases, yet scientists have ...
Phys.org / Borneo's ferret badger is found nowhere else on Earth
A collaborative study has provided the most comprehensive assessment to date of the endangered Bornean ferret badger (Melogale everetti). Weighing only around one kilogram (2.2 pounds), the Bornean ferret badger is a small, ...
Phys.org / Acidic nanoparticles target Parkinson's at cellular source
Inside every human cell, a tiny structure called a lysosome acts like a recycling center, breaking down toxic waste, clearing damaged proteins and helping keep the cell functioning properly. When that recycling center stops ...
Phys.org / Retreating glaciers increase iceberg sightings and reshape deep-sea habitats
The number of icebergs in the Arctic has increased sharply since the 2000s. This is due to the destabilization of large glaciers in northeast Greenland and parts of the Russian Arctic, as well as the increasing mobility of ...
Phys.org / Deep sea an untapped 'evolutionary engine' as dataset yields 500 million unique genes
The deep sea is a unique "evolutionary engine," with one of the richest and most unexplored sources of genetic diversity on Earth, according to a major new study that assessed its potential to transform biotechnology and ...
Phys.org / X-rays reveal how platinum oxidizes in real time inside hydrogen devices
Electrolysers produce hydrogen. Fuel cells, in turn, generate electricity from hydrogen. Both technologies are considered key building blocks of the energy transition, offering well-established solutions for storing, transporting ...
Phys.org / Radar data can help protect birds from wind turbines
Wind turbines generate climate-friendly electricity, but they can pose a danger to migratory birds. A study led by the Swiss Federal Institute for Forest, Snow and Landscape Research (WSL) published in Nature Sustainability ...
Phys.org / Stretchy, soft, and sticky: Advancing the next generation of wearable and implantable sensors
Wearable and implantable biosensors have the potential to revolutionize health care by diagnosing, monitoring, and even treating a wide range of health conditions. Recent innovations in the lab of Wei Gao, professor of medical ...
