A tiny 518-million-year-old sea creature has revealed the earliest known evidence of the structures that eventually became spiders’ fangs. Hidden inside the fossil were pincerlike limbs and preserved soft tissues that help explain how the ancestors of spiders and scorpions evolved into formidable hunters.

Photons traveling through a cloud of atoms can emerge so early that they appear to have spent a negative amount of time inside. Researchers tested whether this was merely a misleading feature of the light pulse by making extremely weak measurements of the atoms. Surprisingly, the atoms confirmed the same negative dwell time. The finding does not break standard physics, but it reveals that one of quantum mechanics’ strangest effects is physically measurable.

Weight loss is not simply a test of willpower. The human brain evolved to protect body fat during times of scarcity, and it can treat a previously higher weight as the new normal, triggering stronger hunger, cravings, and lower energy use after weight loss. This biological “memory” helps explain why many people regain weight after dieting and why medications such as Wegovy and Mounjaro can help by reducing appetite signals, although their effects may fade when treatment ends.

Vanderbilt researchers created the first selective compound designed to inhibit TAOK-1, a poorly understood protein connected to Alzheimer’s disease. They also discovered a second compound that activates the entire TAOK protein family, offering scientists an unexpected new research tool. Together, the compounds could reveal hidden disease mechanisms and point toward new treatment strategies.

Scientists have identified a molecular switch that may help explain why aging makes the brain more vulnerable to diseases such as ALS and Huntington’s. In worms, the protein EPS8 builds up with age and triggers signaling that encourages toxic proteins to clump together, damaging neurons and shortening lifespan. Reducing EPS8 activity prevented these harmful aggregates and preserved nerve function.

Taiwan’s steep, remote mountains have sheltered extraordinary forests containing hundreds of giant Taiwania firs. After years of difficult expeditions, LiDAR mapping, and citizen-science detective work, researchers discovered an 84.1-meter (276-foot) tree, the tallest known in East Asia. They also found dense “temples of giants” where dozens of enormous trees grow together. These ancient forests rank among the world’s most carbon-rich ecosystems.

Thawing Arctic permafrost is releasing ancient carbon into the ocean, raising fears that microbes could turn it into greenhouse gases and accelerate climate change. But sediment cores collected near Canada’s Herschel Island reveal a more reassuring twist: most of this land-based carbon becomes buried in the seafloor, while only about 10 percent is converted into gases.

When atomic nuclei smash together at nearly the speed of light, they create the hottest fluid in the universe, but scientists may have overlooked one of its most important forces. New simulations reveal that extreme acceleration builds up along the edges of quark-gluon plasma, helping drive its explosive expansion. This acceleration may do far more than move the fluid, potentially changing its temperature-like behavior, influencing particle spins, and even reshaping how matter transitions between fundamental states.

Global warming appears to have shifted into a faster gear. After removing the effects of El Niño, volcanic eruptions, and solar cycles, researchers found that the planet has warmed at roughly 0.35°C per decade over the past ten years, compared with just under 0.2°C per decade from 1970 to 2015. The acceleration, which becomes visible around 2013 to 2015, appeared across five major global temperature datasets with more than 98% statistical certainty.

A surprisingly small dose of exercise may deliver major health benefits for adults carrying excess fat around the waist. In a four-month trial involving 315 adults with central obesity, researchers found that completing 75 minutes of brisk interval walking in a single weekly session reduced body fat, trimmed waistlines, and improved cardiovascular fitness about as effectively as splitting the same exercise across three days.

Coastal communities are facing a hidden threat that is making rising seas far more dangerous: the land beneath them is sinking. New research shows that people in densely populated coastal regions experience an average relative sea-level rise of about 6 millimeters per year, nearly three times the global coastal average. Groundwater pumping, oil and gas extraction, heavy urban development, sediment compaction, and natural geological processes are all contributing to the problem.

Dark matter particles may exert a hidden force on one another, but its effects are stranger than expected. An extra attraction helps the particles cluster, yet it also makes dark matter effectively lighter as the Universe expands. That weakens its gravitational impact and usually slows the growth of cosmic structure rather than accelerating it.

The solar wind may be stripping away Mars’ atmosphere by creating giant rolling waves along its outer edge. Data from MAVEN and Tianwen-1 show that these waves form plasma clouds that carry atmospheric particles into space. The process is concentrated on one side of Mars and may have played a major role in drying out the once potentially habitable planet.

Cancer cells rely on powerful genetic switches to keep growth genes running at full speed, but that intense activity can damage their own DNA. The resulting breaks are repeatedly repaired, sometimes with small mistakes that allow new mutations to accumulate. Researchers believe this self-inflicted damage may help tumors evolve while also creating a potential target for new treatments.

A black hole observed during a dramatic 2023 eruption did not simply devour gas from its nearby companion star.

A person’s sleeping brain may reveal warning signs of dementia long before memory problems begin.

More than 150 years after Darwin’s finches helped reshape biology, Galápagos plants are exposing another evolutionary surprise.

New research challenges the decades-old idea that children experience an “adiposity rebound” when their BMI begins rising around age 6. Although BMI returns to earlier levels, a more reliable measure showed that body fat does not rebound at all. The increase appears to come from growing muscle and lean tissue as children prepare for later growth. Researchers say this normal process has been mistakenly treated as an obesity warning sign for 42 years.

Researchers have uncovered a possible biological pathway connecting obesity to Alzheimer’s disease. Obesity appears to raise levels of certain fat molecules that can travel to the brain, disrupt its immune defenses, and promote harmful amyloid buildup.

Ant parenting may have evolved from the same brain systems that once controlled hunger. Researchers found that two chemical signals push clonal raider ants toward either caring for larvae or leaving to forage, with the balance changing as the ants grow older. Similar signals are involved in mammalian caregiving, suggesting that evolution may have followed the same basic blueprint across very different animals.

Signals traveling from the gut to the brain may help turn meals into lasting memories. Rats showed stronger memory activity after consuming nutritious foods, but not after drinking sweet liquids with little or no nutritional value. Blocking the vagus nerve erased this effect and made it harder for the animals to remember where food had been located. Over time, diets high in fat and sugar also weakened this memory system.
