Magnetic storage technologies, which store information in the direction of magnetization, play an essential role in modern data storage. Hard disk drives (HDDs) are widely used for long-term storage, while nonvolatile magnetic random-access memory (MRAM) is emerging as a
Food fraud is costing the UK economy up to £2 billion every year, according to the first study to calculate its full economic impact. The research, from the University of Portsmouth, estimates that food fraud costs between £400 million and £2 billion annually, making it one of
Some U.S. adults are using artificial intelligence for financial guidance, but it's far from the most trusted source of advice, according to a new Gallup survey conducted in partnership with Edward Jones, a financial services firm.
Within our solar system, Uranus is a geometric oddball. Its spin axis tilts more than 90° from its orbit, so it essentially rolls on its side through space. In contrast, Earth and other planets tilt only moderately or not at all. What's more, the ice giant's magnetic field is
Added protein is showing up in foods from breakfast cereal to pasta, but not many condiments … yet. Researchers have now developed an enriched tomato ketchup by incorporating protein extracted from algae. A panel of taste testers preferred recipes containing up to 3% added
A tall glass of ice water isn't just a thirst quencher; it's also an everyday example of coexisting phases. Water can exist simultaneously in both liquid and solid phases. As it turns out, this phase duality can also exist in more exotic quantum materials, in ways that are far

Chemical analysis of Bronze Age iron objects indicate that Greek nobles may have indulged in signet rings made with precious metal from the sky.
One of the most important milestones in the early life of an organism is when the embryo breaks symmetry and arranges itself to form the head (anterior) at one end and tail (posterior) at the other end. Scientists have used the common fruit fly (Drosophila melanogaster) for
A research team led by Koji Ishiya of Kanazawa University reconstructed exceptionally high-coverage genomes from two ancient individuals in Japan: IY1, a woman from the Initial Jomon period who lived about 8,300 years ago, and DO, a man from the Middle Yayoi period who lived

Snails are particularly active after a rain shower. Even on the Max Planck Campus in Potsdam-Golm, common brown-lipped snails (Cepaea nemoralis) leave behind shiny trails of mucus. Researchers from the "Biomaterials" department saw the slime as a promising natural material. The
Zooming from her office, Michigan State University researcher Kelly Kapsar showed satellite images from across the United States. In some, different colors revealed the precise heights of the forested ridges in the Sierra Nevada or the craggy peaks of the Rockies and the
A research team has identified the transcription factor C/EBPγ as a novel regulator that simultaneously promotes epithelial-mesenchymal transition (EMT) and DNA double-strand break repair in lung adenocarcinoma cells. The findings, published in Cell Death Discovery, provide new
An eight-year international research effort has produced the most comprehensive review of Honduras' mammals since 1998, verifying 227 native species across 146 genera and 42 families, along with three introduced rodent species. The study, published in the open-access journal

A global constellation of neutrino detectors is creating a never-before-seen view of the radioactive elements that power Earth’s tectonic heat engine. The post Neutrinos From Deep Inside Earth Provide a New Picture of the Mantle first appeared on Quanta Magazine
Linus Pauling was widely mocked for claiming that vitamin C could fight cancer, especially after trials using vitamin C pills showed no benefit. Researchers now know that intravenous vitamin C reaches vastly higher concentrations and can behave more like an experimental cancer
On Mother's Day weekend in May 2024, Earth experienced its most powerful geomagnetic storm in two decades, spawning auroras—the ribbony bands of light in the nighttime skies in the Northern and Southern hemispheres—that may have been among the strongest displays on record in
The artificial intelligence system largely accomplished the task it was built to solve, and researchers outside DeepMind have already been carrying its work forward
The last common ancestor of all living things may not have been alive at all
Blocking the glycine transporter SLC6A20 restored important brain signaling and improved social, communication, and repetitive behaviors in autism-related mouse models. The treatment also worked in human brain organoids and showed lasting effects in adult mice, suggesting the
Scientists have demonstrated that heat can move through a crystal in focused, wave-like rays at room temperature instead of spreading randomly. The breakthrough could make it possible to route heat around sensitive parts of next-generation chips and quantum devices.
Republicans and Democrats, renters and homeowners, rich and poor—agree on at least one thing: Buying a home is harder today than it was for their parents. The latest UCI-OC Poll suggests that's just the beginning of the problem.
Astronomers have found evidence that one of the most massive white dwarfs known has an oxygen-neon core instead of the more common carbon-oxygen core. The finding is important because the composition of a white dwarf's core determines how it will evolve. A paper outlining this
After 49 years in space, NASA’s Voyagers are running low on power—but an audacious move should extend the tenures of the two spacecraft

A recent study by MSU entomologists Jen Roedel, Karma Thomas and Zsofia Szendrei found that urban growers' use of pollinator management practices is driven more by access to educational resources, labor and other farming support than by demographics or the pollination needs of
A ten-month Antarctic experiment found that astronauts may struggle not only with loneliness but also with spending too much time around the same people. Frequent contact was linked to greater tension and mistrust, while the crew increasingly divided into cultural and
Few tax issues generate more public frustration than big corporations paying little, or sometimes nothing, in federal income tax. Since 2018, U.S. corporations have faced a 21% federal corporate income tax rate, the lowest rate in decades and down from a top rate of 53% in 1969.
Folding a piece of paper makes it thicker. How many folds would it take to reach the moon—and beyond?
Smoking in movies and TV is up, and “cigfluencers” have become a thing, but lags in data make it unclear if the vibe shift has any reality to it
Earth’s molten iron core unexpectedly reversed direction beneath the Pacific, revealing a dramatic change in the hidden engine that creates our planet’s magnetic field. Satellite data suggest the surge is already weakening, raising the possibility that the deep-Earth upheaval
Smoking rates remain low, but experts say social media, stress and shifting attitudes could be fueling a cigarette revival

Several enormous Megalodon vertebrae thought to have been destroyed in 1989 were found sitting unnoticed on a museum shelf. Their analysis strengthens evidence that the giant shark could exceed 24 meters (79 feet) in length and live for nearly a century. Researchers also
Beginning around age 50, the brain’s memory center appears to lose many of its longtime immune cells and replace them with more inflammatory ones. This surprising shift may help explain how normal aging sets the stage for Alzheimer’s disease and dementia.
Many parents have mixed feelings about the unrestricted use of artificial intelligence (AI) for schoolwork. They are concerned about the potential impact on their child's ability to learn but also don't want them to be left behind if other young people are using AI.
