At the beginning of the 20th century, Santiago Ramón y Cajal, often called “the father of modern neuroscience,” made it clear: In adults, “the nerve paths are something fixed, ended, and immutable. Everything may die, nothing may be regenerated,” he wrote. The inability of adults to produce new neurons was pretty much the central dogma of neuroscience until the 1960s. But as with a lot of fathers in that decade, a younger person challenged Ramón y Cajal’s decree.In 1962, Josef Altma ...read more

Snapshots of colorful galaxies and planets show that the beauty of our universe knows no bounds, and recent images of glowing space gas and dust captured by NASA are no exception. The James Webb Space Telescope (JWST) has caught yet another visual spectacle, depicting layers of interstellar material illuminated by a supernova in a phenomenon known as a thermal light echo.Getting a glimpse of the brilliant scene through JWST, a team at NASA created a 3D scan of the interstellar material that disp ...read more

They don’t always own up to it, but many parents play favorites, treating their more favored children differently than their less favored. According to recent research in the Psychology Bulletin, certain children tend to be the favorites, as parents may be more inclined to treat their daughters, as well as their agreeable and conscientious children, better.“Differential treatment from parents can have lasting consequences for children,” said Alexander Jensen, a study author and an associat ...read more

The desert is one of the harshest environments to live in. It can be extremely hot during the day and freezing cold at night. There is sparse vegetation and little shade. The terrain is often rough, and to top it all off, there is minimal water. Desert inhabitants must be adaptable to survive these harsh conditions. As humans, to thrive in desert life, we must find ways to stay hydrated, stay out of the sun, and find food and shelter. It’s much easier to survive in the desert now, with modern ...read more

The objects may have been sacrificial do ...read more

When the German computer pioneer Konrad Zuse built the world’s first programmable computer in war time Berlin, it performed floating point arithmetic at a clock speed of between 5 and 10 Hz. The machine was deemed unnecessary for the German war effort and never used for everyday calculations. In 1943, it was destroyed during an Allied air raid. Nevertheless, the Z3, as it was called, gave Zuse a strong claim to be the inventor of the modern computer. After the war, the clock speed of computers ...read more

Contemporary snow leopards are rare — and fossils of their ancient ancestors are even more scarce. Researchers have now identified and examined million-year-old bones of the big cat and have come to some surprising conclusions about how it adapted to the Ice Age and survived as a species since then. Their analysis has been published in the journal Science Advances.Learning About Snow Leopard SurvivalThe skull of the leopard of Algar da Manga Larga, deposited at the Geological Museum of Lisbon. ...read more

New findings published in the journal Nature suggest that women were at the top of British Iron Age societies. After examining ancient genomes uncovered in a cemetery in Dorset, an international research team determined that this community had a strong female-line descent, which may be a first for early Europe. Uncovering Ancient GenomesDurotrigian burial of a young woman from Langton Herring sampled for DNA (c) Bournemouth University.
