Dogs use two-word button combos to communicate
A new study shows that dogs trained to use soundboards to 'talk' are capable of making two-word button combinations that go beyond random behavior or simple imitation of their owners.

Earliest deep-cave ritual compound in Southwest Asia discovered
A cave in Galilee, Israel, has yielded evidence for ritualistic gathering 35,000 years ago, the earliest on the Asian continent.
Existing EV batteries may last up to 40% longer than expected
Consumers' real-world stop-and-go driving of electric vehicles benefits batteries more than the steady use simulated in almost all laboratory tests of new battery designs, a new study finds.
Could a decades-long debate about the mysterious movements of stars in Omega Centauri, the largest star cluster in the Milky Way, finally be resolved?
New ocean predator discovered in the Atacama Trench
Characterized by darkness and intense pressure, the ocean's hadal zone seems uninhabitable, yet dozens of unique organisms call it home. Each species discovered there adds a crucial piece to the puzzle of how life has evolved and even thrives in one of Earth's most extreme environments. A new study highlights one of those species -- the newly named Dulcibella camanchaca. This crustacean is the first large, active predatory amphipod from these extreme depths.
Universe expansion study confirms challenge to cosmic theory
New observations from the James Webb Space Telescope suggest that a new feature in the universe -- not a flaw in telescope measurements -- may be behind the decade-long mystery of why the universe is expanding faster today than it did in its infancy billions of years ago.
Battery-like computer memory keeps working above 1000°F
Computer memory could one day withstand the blazing temperatures in fusion reactors, jet engines, geothermal wells and sweltering planets using a new solid-state memory device developed by a team of engineers.
A new study is helping solve the mystery as to why the brain shrinks in a unique pattern, known as atrophy, in chronic traumatic encephalopathy (CTE). This research provides novel evidence that cumulative repetitive head impacts are driving the specific patterns of brain degeneration found at the base of the folds of the surface of the brain, known as the cortical sulcus.
Loneliness and isolation: Back to pre-pandemic levels, but still high, for older adults
Loneliness and isolation among older Americans have mostly returned to pre-pandemic rates, but that still means more than one third of people age 50 to 80 feel lonely, and nearly as many feel isolated, a new national study shows.
Astronomers find the smallest asteroids ever detected in the main belt
Astronomers have found a way to spot the smallest, 'decameter,' asteroids within the main asteroid belt. They used their approach to detect more than 100 new asteroids, ranging from the size of a bus to several stadiums wide, which are the smallest asteroids within the main belt detected to date.
Researchers discover a genetic disposition increasing the risk of breast cancer metastasis
Metastasis is responsible for 90 percent of cancer deaths. Researchers have found that the mutations driving it may stem from a commonly inherited variant of the PCSK9 gene.
Readers trust news less when AI is involved, even when they don't understand to what extent
Researchers have published two studies in which they surveyed readers on their thoughts about AI in journalism. When provided a sample of bylines stating AI was involved in producing news in some way or not at all, readers regularly stated they trusted the credibility of the news less if AI had a role. Even when they didn't understand exactly what AI contributed, they reported less trust and that 'humanness' was an important factor in producing reliable news.
A healthy diet helps the weighty battle with chronic pain
New research shows that adopting a healthy diet can reduce the severity of chronic pain, presenting an easy and accessible way for sufferers to better manage their condition.
Bucking conventionality, boys in Norway are making early gains in reading English as a second language and even outperforming girls at age 10 and 13 -- a new a study of more than one million students suggests.
