Why does "Superheated magma may power towering lava fountains" matter? [Unclear]
Scientists studying magma from the 2021 Tajogaite eruption on La Palma have discovered that extreme heat can dramatically change how an eruption unfolds. When magma becomes superheated, it can dissolve the tiny crystal s…

Superheated magma may power towering lava fountains
Scientists studying magma from the 2021 Tajogaite eruption on La Palma have discovered that extreme heat can dramatically change how an eruption unfolds. When magma becomes superheated, it can dissolve the tiny crystal seeds that normally trigger crystallization, allowing the molten rock to remain fluid far longer as it rises.
NASA’s Curiosity rover finds a mysterious honeycomb landscape on Mars
NASA’s Curiosity rover has entered a Martian valley covered by an astonishing “sea” of tiny polygon-shaped fractures. The honeycomb patterns, each only a few inches wide, stretch across the landscape and even wrap around a nearby 20-foot-tall butte.
Scientists found two mysterious ‘ghost’ ancestors hiding in our DNA
Modern humans carry DNA from two mysterious extinct lineages in addition to Neanderthals and Denisovans. Their hidden genetic legacy shows that our evolutionary past was shaped by repeated mixing among many different human groups.
Black holes may spit out nearly as much matter as they swallow
A black hole observed during a dramatic 2023 eruption did not simply devour gas from its nearby companion star. It also expelled large amounts of material through powerful jets and winds, even after the outburst had nearly faded. The results suggest black holes may continue reshaping their surroundings long after their brightest fireworks end.
AI can tell if your brain is aging faster than you are
A person’s sleeping brain may reveal warning signs of dementia long before memory problems begin. Researchers used machine learning to analyze EEG recordings from about 7,000 adults and found that an older-than-expected “brain age” was tied to a sharply higher dementia risk. Every additional 10 years of brain aging raised that risk by nearly 40%.
Scientists found evolution repeating itself in the Galápagos Islands
More than 150 years after Darwin’s finches helped reshape biology, Galápagos plants are exposing another evolutionary surprise. Giant daisies repeatedly developed similar heat-tolerant leaf shapes, but each lineage used a different combination of genes. Researchers also found major genetic differences among isolated populations, suggesting new species may be forming right now.
A 42-year-old childhood obesity theory may be wrong
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.
Scientists discover how obesity may fuel Alzheimer’s disease
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. Correcting this fat imbalance improved memory and brain function in Alzheimer’s models.
Scientists discover why poor sleep may harm some brains more
A gene involved in the brain’s overnight cleaning system may change how strongly poor sleep affects Alzheimer’s-related brain changes. The findings point toward more personalized prevention strategies based on both genetics and sleep habits.
New process turns plastic waste into hydrogen fuel while trapping the carbon
A new chemical process can transform three of the most common plastics into high-purity hydrogen without sorting them first. The technique operates at much lower temperatures than traditional gasification and captures most of the plastic’s carbon in solid or liquid forms instead of releasing it as carbon dioxide.
Ant brains reveal how evolution turned hunger into parenting
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.
Tiny black holes may be secretly exploding stars across the Milky Way
Primordial black holes may occasionally pass through white dwarf stars and trigger enormous Type Ia supernova explosions. Researchers found that these events could explain chemical patterns seen in supernova remnants, nearby explosions, and stars across the Milky Way.
