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 mana
Ultrafast X-rays revealed how a molecule converts absorbed light into motion in just trillionths of a second。 Individual atoms recorded different stages of the process, opening a powerful new window into light-driven 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 alte
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
Astronomers may have been listening for alien civilizations in only a small slice of the radio spectrum while overlooking a largely unexplored range of higher frequencies。 Using archived data from the ALMA telescope in Chile, researchers conducted the observatory’s first SETI survey, searching for narrow signals that could indicate advanced technol
A new cooking method could make French fries crispier in less time while significantly limiting how much oil they absorb。 Researchers propose combining microwave heating, which keeps oil out, with conventional frying, which provides the crunch consumers expect
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 spec
NASA’s Psyche spacecraft aced its Mars flyby, using the planet’s gravity to speed toward its 2029 encounter with a metal-rich asteroid。 The spacecraft tested its cameras, magnetometer, and particle-detecting instruments, capturing unusual views of Mars and measuring its magnetic environment。 It also detected neutrons from the planet and spotted the
NASA’s Swift Observatory observed a supermassive black hole ripping apart a star more than 30,000 light-years from the center of a distant galaxy。 The extraordinary flare briefly outshone its entire host galaxy in ultraviolet light and revealed a black hole about a million times the Sun’s mass
NASA astronaut Chris Williams and two Roscosmos cosmonauts are back on Earth after spending 241 days aboard the International Space Station。 Their journey covered more than 102 million miles and included 3,856 trips around the planet
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
An appeals court in Canada acquitted Brandon Klayme of charges related to child sexual abuse imagery。 His Kik username had one less underscore than another account that was involved
Songbirds appear to have evolved through rare explosions of change separated by long periods of slower development。 Many of those bursts lined up with major climate shifts, suggesting that environmental upheaval can reshape life in powerful ways
