NASA’s Curiosity Mars Rover Discovers Field of Honeycomb Textures

As NASA’s Curiosity rover recently began climbing up a Martian valley nicknamed “Valle Grande,” it sent back images that were a familiar sight to mission scientists: honeycomb-like textures called polygonal fractures, each one about 1.5 to 3 inches (4 to 8 centimeters) across. The mission has spotted small patches of these geometric shapes several times […]

NASA Webb Explores Family Tree of Newly Discovered Distant Objects

Since their discovery by NASA’s James Webb Space Telescope in 2022, little red dots (LRDs) have been the subject of great interest to astronomers. Understanding the nature of these extremely distant, compact red sources has been a puzzling scientific endeavor. One popular theory is that little red dots are supermassive black holes known as active […]

Repeated use of saunas could help people cope better in heatwaves, scientists say

Growing number of studies assessing whether heat training can help people prepare for scorching temperaturesEven as summer temperatures soar, the sauna trend is booming, with some venues touting them as a way to beat the heat. But while experts have urged caution about sweating it out in hot weather, a growing number of studies are considering whether heat training could help people prepare for heatwaves.With parts of the UK experiencing their fourth heatwave of the year, the UK Health Security

Scientists find a simple way to stop cavities without drilling

A liquid brushed onto cavities in seconds may spare many young children from pain, infection, and surgery. A major U.S. trial found that silver diamine fluoride stopped decay in more than half of treated baby teeth. The treatment requires no drilling, shots, or sedation, although it does permanently darken the decayed area.

Your gut may help your brain decide what to remember

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.

Why are so many dead bumblebees appearing on sidewalks?

Bumblebees naturally have short lives, but extreme heat and human activity are making survival harder. Pesticides can poison bees or destroy the flowers they depend on, while habitat loss leaves them with fewer safe places to live and feed. Protecting native plants and using fewer chemicals could help these vital pollinators recover.

A tiny molecular basket unlocks a powerful new kind of chemistry

Rice University chemists have found a new way to make neodymium, a rare-earth metal, interact with oxygen. Using a specially designed molecular structure described as a “basket,” the team positioned the atoms so they could form a bond once thought unlikely. The breakthrough produced highly reactive compounds that could eventually give chemists alternatives to iron-based molecules used in biological reactions and chemical manufacturing.

Can’t sleep in the heat? These 8 tricks could save your night

Sleeping well during a heatwave starts with stopping the home from overheating. Close blinds against strong sunlight, ventilate when the air outside becomes cooler, and avoid using heat-producing appliances during the hottest hours. Moving to a cooler room, choosing light bedding and using fans or ice packs safely can also make hot nights more manageable.

The search for life on Jupiter's icy moon Europa just got more complicated

Europa’s hidden ocean has made the icy moon one of the solar system’s most promising places to search for habitable conditions. Scientists have hoped that water from this deep ocean might rise through cracks and form shallow reservoirs that future spacecraft could more easily study. New simulations suggest that journey is unlikely because turbulent water would rapidly lose heat, form ice crystals, and clog the fractures, sometimes within hours.

Earth’s hidden “gold kitchen” lies beneath the seafloor

Deep beneath submarine volcanoes, Earth may be running a natural “gold kitchen.” By analyzing volcanic glass from the Kermadec island arc north of New Zealand, researchers found that water-rich mantle repeatedly melts beneath subduction zones, gradually concentrating gold in rising magma. The process works because intense melting breaks down sulfur-rich minerals that normally trap gold, releasing the metal into the melt.

A grocery-store audit found that many foods marketed for toddlers may be far less healthy than parents expect. Of nearly 2,800 products examined in Texas, 81% were ultra-processed, and almost half failed at least one World Health Organization nutrient standard, often because they contained too much sugar, sodium, fat, or too many calories.

Deep beneath Japan’s mostly submerged Kikai caldera, scientists have discovered a vast magma reservoir that appears to be filling again. The volcano produced the largest eruption of the Holocene 7,300 years ago, and seismic surveys now show that fresh magma has likely entered the same underground system responsible for that catastrophe.
