Phys.org / NASA telescope honors Nancy Grace Roman, architect of space-based astronomy
The Nancy Grace Roman Space Telescope is set to launch this weekend aboard a SpaceX rocket from Kennedy Space Center in Florida. When it becomes operational early next year, it will transform our view of the universe.
Phys.org / One molecule, one photon: Entanglement makes an imperceptible recoil measurable
For decades, light has been used to understand the molecular structures of matter. A sample is irradiated with light, and measurements determine the wavelengths at which it is absorbed. Since each molecule absorbs light at ...
Phys.org / Dry seeds preserve fully formed mitochondria, unlocking rapid energy at germination
The majority of plant seeds have the special ability to almost completely dry out and yet remain viable. While most living cells die with a 90% loss of water, cells in seeds enter a biological state of dormancy. With a moisture ...
Medical Xpress / Fruit fly study sheds light on how forgotten memories return and change
As they explore the world, humans and other animals create many memories that they will later recall and that might inform their future actions. Over time, however, some of these memories can be forgotten or become less nitid, ...
Phys.org / Widespread use of AI tools could make it harder to craft effective business communications
Generative AI tools such as ChatGPT make it easier for business owners to produce polished pitches, business plans and other communications, but according to new research from The University of Manchester and Canada's University ...
Phys.org / Did ocean motion carve Enceladus's tiger stripes?
Saturn's moon Enceladus sports a thick shell of ice surrounding a liquid water ocean. As though scraped by an enormous claw, four parallel cracks slash across its south pole. Each about 500 meters (1,600 feet) deep, 2 kilometers ...
Medical Xpress / Prostate medication linked to fewer complications after heart attack
Men are likely to suffer more extensive heart attacks than women. Studies have shown that male sex hormones, such as testosterone, intensify inflammation during an acute heart attack and lead to a larger area of damage. According ...
Medical Xpress / Txn1 mutant rats: A valuable translational model of chronic kidney disease
Chronic kidney disease (CKD) is a major health burden affecting approximately one in 10 adults globally. Even with improved treatments, many patients continue to experience worsening kidney function, resulting in the need ...
Phys.org / Species discoveries reveal emerging biodiversity hotspots worldwide
We share our planet with millions of plants and animals. This variety of life is known as biodiversity, a term encompassing everything from microscopic genes to entire ecosystems, such as deserts and vibrant coral reefs.
Phys.org / Cellular 'glue' helps epithelial tissues engulf dead cells while staying sealed
A protein that sticks cells and tissues together has been found to have a surprising second job: helping cells that are packed into a continuous sealed layer, also known as epithelial cells, engulf nearby dead cells.
Phys.org / Why a newly formed lake is sparking fears of more flooding along the Nepal-China border
Even as rescuers worked through mud and debris Friday in areas devastated by a catastrophic flash flood along the Himalayan border between Nepal and China, authorities warned that a newly formed, overflowing lake could trigger ...
Tech Xplore / Bifur-circuits let shape-changing devices keep electrical connections intact
A new set of modular components allows users to create reconfigurable smart devices with electrical connections that keep working no matter what shape the structure forms.
