Scientists find natural compounds that hit COVID-19 from every angle

A little-known tree from Brazil’s Atlantic Forest may hold a surprising weapon against COVID-19. Researchers discovered that compounds called galloylquinic acids, extracted from its leaves, can attack SARS-CoV-2 on multiple fronts—blocking the virus from entering cells, disrupting its replication, and even dampening harmful inflammation. Unlike many antivirals that target just one part of the virus, these natural compounds act in several ways at once, potentially making it harder for resistance to develop.

Webb space telescope finds a giant galaxy that doesn’t spin

Astronomers using the James Webb Space Telescope have spotted something that shouldn’t exist—at least not so early in the universe. A massive galaxy, formed less than 2 billion years after the Big Bang, appears to have no rotation at all, a trait usually seen only in much older, evolved galaxies. This challenges current theories that young galaxies should still be spinning from their formation.

This strange planet pair shouldn’t exist, but it does

A bizarre planetary pairing 190 light-years away is challenging everything astronomers thought they knew about how worlds form. A “lonely” hot Jupiter — typically found without nearby companions — is sharing its system with a smaller mini-Neptune tucked even closer to the star, a setup once thought nearly impossible.

MIT scientists discover millions of “silent synapses” in the adult brain

MIT neuroscientists have uncovered a surprising secret hidden in the adult brain: millions of “silent synapses,” dormant connections that lie in wait until new learning calls them into action. Once thought to exist only in early development, these inactive links make up about 30% of synapses in the adult cortex and can be rapidly activated to form fresh memories.

AI lets chemists design molecules by simply describing them

Creating complex molecules usually requires years of experience and countless decisions, but a new AI system is changing that. Synthegy lets chemists guide synthesis and reaction planning using simple language, while powerful algorithms generate and evaluate possible solutions. The AI doesn’t just compute—it reasons, scoring pathways and explaining which ones make the most sense.

4,000-year-old tablets reveal magic spells, kings feared, and a beer receipt

Long-forgotten ancient tablets have been decoded, uncovering a mix of magic, politics, and daily life from early civilizations. Among the discoveries are rare anti-witchcraft rituals meant to protect kings and a regnal list that could point to the real-life existence of Gilgamesh. Some texts reveal correspondence between rulers, while others show the rise of complex bureaucracies. One tablet even records something as ordinary—and relatable—as a receipt for beer.

Scientists just created exotic new forms of matter that shouldn’t exist

A new quantum physics study reveals that simply changing a magnetic field over time can unlock entirely new forms of matter that don’t exist under normal conditions. By carefully “driving” materials with timed magnetic shifts, researchers created exotic quantum states that could be far more stable and resistant to errors—one of the biggest challenges in quantum computing. This breakthrough suggests that the future of quantum technology may depend not just on what materials are made of, but how they’re manipulated in time.

This simple blood test might detect depression before symptoms appear

A new study suggests depression may soon be detectable through a simple blood test—by tracking how certain immune cells age. Researchers found that accelerated aging in monocytes, a type of white blood cell, is closely tied to the emotional and cognitive symptoms of depression, like hopelessness and loss of pleasure, rather than physical symptoms such as fatigue.

Evolution isn’t random. Scientists find the same genes used for 120 million years

Evolution seems to follow a script more often than expected. Researchers found that distantly related butterflies and moths have reused the same pair of genes for over 120 million years to produce strikingly similar warning colors. Rather than altering the genes themselves, evolution modifies how they’re switched on and off. This discovery hints that life may evolve in more predictable ways than previously believed.

Scientists found the brain doesn’t start blank, it starts full

The brain’s memory center may begin life more like a crowded web than an empty canvas. Researchers discovered that early neural networks in the hippocampus are dense and seemingly random, then become more organized by shedding connections over time. This pruning process creates a faster, more efficient system for linking experiences and forming memories. It challenges the idea that the brain starts from scratch.

Scientists discover a hidden brain “cleaning” effect triggered by movement

Scientists have uncovered a surprising link between simple body movement and brain health: every time you tighten your abdominal muscles—even slightly—your brain may gently sway inside your skull. This subtle motion, triggered by pressure changes in connected blood vessels, appears to help circulate cerebrospinal fluid around the brain, potentially flushing out harmful waste.

Hidden ocean heat is creeping toward Antarctica’s fragile ice shelves

Deep beneath the Southern Ocean, a quiet but alarming shift is underway: warm water is creeping closer to Antarctica, and scientists are now seeing it clearly for the first time. By combining decades of ship data with robotic float measurements and machine learning, researchers uncovered that a massive pool of heat—circumpolar deep water—has expanded and edged toward the continent over the past 20 years.

Bronze Age mines discovered in Spain may explain Scandinavian metal mystery

Archaeologists have uncovered six previously unknown Bronze Age mines in southwestern Spain, offering a striking new clue about where the metal in ancient Scandinavian artifacts may have come from. Found near Cabeza del Buey, the sites include everything from small extraction zones to larger mining operations—one even packed with around 80 stone axes used to crush ore. These mines contain copper, lead, and silver, key materials that powered trade networks thousands of years ago.
