Researchers discovered that raising the protein Sox9 can help the brain’s astrocytes clear out toxic plaque buildup linked to Alzheimer’s. In mouse models that already showed memory problems, activating these cells improved cognitive performance. The treatment also reduced
Ideas about Vikings and Norse mythology come mostly from much later medieval sources, leaving plenty of room for reinterpretation. Over centuries, writers, politicians, and artists reshaped these stories to reflect their own worldviews, from romantic heroism to dangerous
From woolly mammoths to giant sloths, via some lesser-known ice-age beasts like 'killer koalas', the visuals in this documentary are simply astounding
Scientists flew the XL-Calibur telescope on a high-altitude balloon to measure polarized X-rays from Cygnus X-1. These measurements reveal details about the chaotic, superheated material swirling around black holes. The team also captured data from the Crab pulsar and achieved
Researchers have pinpointed a super-Earth in the habitable zone of a nearby M-dwarf star only 18 light-years away. Sophisticated instruments detected the planet’s gentle tug on its star, hinting at a rocky world that could hold liquid water. Future mega-telescopes may be able
A massive solar storm in May 2024 gave scientists an unprecedented look at how Earth’s protective plasma layer collapses under intense space weather. With the Arase satellite in a perfect observing position, researchers watched the plasmasphere shrink to a fraction of its usual
Researchers taught young loggerhead turtles to associate certain magnetic fields with feeding, prompting a distinctive dance when they recognized the signal. After a magnetic pulse briefly disrupted their ability to feel magnetic forces, the turtles no longer performed the
An increasingly strong case is being made to bring inequality into discussions about climate change. The logic behind this has been set out by leading international institutions such as the International Labor Organization, the UN Environmental Program and the Network for
Fifteen years ago, when I started studying the international dating industry, few people took the subject seriously. The term "mail-order bride" was treated as a punch line—something outdated, associated with lonely men and poor women who migrated from Eastern Europe, Asia or
This year's COP30 comes after the international Agreement on Marine Biological Diversity of Areas beyond National Jurisdiction (BBNJ) finally acquired the required number of ratification votes by United Nations member states.
For over 200 years, native oysters (Ostrea edulis) have been absent in Dublin Bay. Once abundant along the Irish coast, they thrived in the sheltered estuaries and tidal flats that shaped the city's maritime life.
The government's vision for higher education in England, set out in a recent policy paper, includes some changes that will benefit students from poorer backgrounds.
Nations sealed a modest deal at the UN climate summit in the Amazon Saturday, as Europe and others dropped their demands for a plan to phase out fossil fuels after fraught negotiations with oil-producing countries and emerging economies.
For Las Vegas to keep its taps flowing, Rep. Susie Lee says this one drought measure must survive federal spending purges: water recycling.
I have to confess, despite spending years gazing at the night sky, telescope at the ready, tracking planets and hunting for deep sky objects, I only actually saw the Man in the Moon about five years ago. There I was, exploring lunar maria and highland regions, and I'd somehow
The 2025 United Nations Climate Change Conference (sometimes referred to as COP30) is taking place in Brazil.
Scientists discovered that lowering a specific molecule helps microglia switch into a protective state that quiets brain inflammation in Alzheimer’s. A small group of these cells seems to have an outsized ability to keep the brain healthier. When a key signal is removed from
As the Trump administration carries out what many observers say are illegal military strikes against vessels in the Caribbean allegedly smuggling drugs, six Democratic members of Congress issued a video on Nov. 18, 2025, telling the military "You can refuse illegal orders" and
A new nasal-delivered nanotherapy shows promise against aggressive glioblastoma tumors. By activating the STING immune pathway using gold-core spherical nucleic acids, researchers were able to reach the brain without invasive surgery. When paired with drugs that boost T-cell
Worker bees stage coordinated revolts when viral infections weaken their queen and lower her pheromone output. This disruption drives many of the queen failures that beekeepers struggle with today. Field trials show that synthetic pheromone blends can prevent untimely
As the climate crisis accelerates, there's a desperate need to rapidly reduce carbon dioxide levels in the atmosphere, both by slashing emissions and by pulling carbon out of the air.
Scientists have uncovered a surprising second type of lion roar, using AI to decode vocal signatures with remarkable precision. This breakthrough sheds new light on how lions communicate and offers a powerful new tool for conservationists racing to protect shrinking populations.
If I asked you to imagine your dream snog, chances are it wouldn't be with a Neanderthal; burly and hirsute as they may be. However, my team's new research suggests that these squat beefcakes might have been right up your ancestors' street.
Researchers discovered that copper oxide catalysts form metallic copper mid-reaction, triggering a dramatic boost in ammonia output. The insight offers a roadmap for designing cleaner, more efficient ammonia-production technologies.
Marine animals inevitably eat what we toss in the ocean, including pervasive plastics—but how much is too much?
