Modern researchers have only recently started to piece together the vivid blue adorning ancient Egyptian tombs, sculptures, and jewelry over millennia. Originally created about 3100 BCE and lost to time by the Renaissance, this pigment known as Egyptian blue is the first synthetic color used in humans Now, a group of Washington State University researchers ...
For decades, the fossilized bones of Australia’s megafauna giant marsupials once rovers of the continent have murmured secrets just beyond our reach. Too often, these remains are scattered, degraded, or insufficient to recognize. But now thanks to an unexpected key collagen scientists have opened a fresh window into the past. Three massive extinct species, a ...
One of the strongest voices in the world of wildlife protection has been lost. Valmik Thapar, the fabled “Tiger Man,” died at his Delhi residence and left behind a legacy as big as the jungles he fought to protect.

The Black Death was an evolutionary arms struggle between humanity and one of the most clever pathogens in history, not only a mediaeval horror. The bacterium causing the plague, Yersinia pestis, evolved to guarantee its survival rather than merely killing millions. Now, revolutionary studies show how the plague changed its genetic code to become less ...
For decades, the story of human evolution has been pieced together from fragments of fossilized bones, stone tools, and, more recently, ancient DNA. But what happens when DNA degrades beyond recovery, leaving scientists with only enamel and dentin to decode the secrets of our ancestors? A groundbreaking new study has cracked the code, using proteins ...
The White House presented the announcement of an executive decree to “restore gold standard science” as a commitment to transparency, rigor and trust in government-sponsored research. On the surface, there is a promise of the reforms in science opponents argue that the directive could be a trojan horse, that grants political appointees the unheard of ...
Finding a 1,000-year-old Viking arm-ring made of gold, beautifully created by tying eight gold rods in a row, metal detectorist Ronald Clucas would cause waves in the field of archeology in a peaceful spring morning in 2025. The relic was discovered on the Viking trading post Isle of Man, the piece of art provides an ...
Cosmologists have believed for a long time that dark energy the mysterious factor that accelerates the expansion of the universe–was a constant, indestructible presence. However, the latest information obtained from the Dark Energy Spectroscopic Instrument (DESI) indicates this is not the situation. Instead, the impact of dark energy may diminish as time passes, a finding ...
For a long time, mainly for blood cancers such as lymphoma and leukemia CAR T-cell therapy has provided a glimpse of possibility in the treatment of cancer. The latest clinical trial conducted in China has rebutted that notion with a previously unheard-of result against solid tumors. They are a difficult type of cancer to treat. ...
Astronomers have been narrating a dramatic tale about the fate of our galaxy for more than a century: the Milky Way is relentlessly on collision with Andromeda, its enormous neighbor. Once judged unavoidable within 4–5 billion years, the cosmic smash-up would destroy spiral galaxies and create a new, shapeless elliptical galaxy known as “Milkomeda.” But ...
