It's autumn in the Southern Hemisphere, which means it's fog season in the Victorian Alps. NASA's Terra satellite captured this view of morning fog filling valleys in several national parks across the mountains of eastern Victoria in May.
Archaeologists have found something unexpected inside a 1,600-year-old Roman-era Egyptian mummy: a fragment of Homer's Iliad. It wasn't placed beside the body, but inside the mummy's abdomen. But the real surprise isn't just where the fragment was found. It's how it got there.
Scientists at UBC Okanagan have uncovered how plants produce mitraphylline, a rare natural compound with promising anti cancer potential. The team identified two enzymes that work together to build the molecule’s unusual twisted structure, solving a mystery that had puzzled
Scientists at the University of Maryland, Baltimore County, have uncovered a crucial trick used by enteroviruses—the group behind diseases like polio, myocarditis, encephalitis, and even the common cold—to reproduce inside human cells. The team captured, in unprecedented
Researchers found a new way to kill harmful “zombie” cells that linger after chemotherapy and help cancers become more aggressive. These senescent cells survive by relying on a protective protein called GPX4, even while sitting on the edge of a deadly iron-triggered collapse.
Iodine deficiency is often seen as a problem of the past, but this isn't entirely true. During the 20th century, the iodization of salt became one of the most effective public health interventions for preventing conditions caused by a lack of this mineral, including goiter
Ganymede, Jupiter's largest moon, is also the solar system's largest satellite, even larger than the planet Mercury. It is also the only celestial body aside from Earth (and the gas giants) to have an intrinsic magnetic field. As if this didn't make the icy body interesting
Gravitational wave researchers working on the world's most sensitive scientific instruments have found a way to tune their detectors using a process akin to the pitch-correction used in music production.

Harbor porpoises were once found across a much wider area of the Baltic Sea than they are today, including regions where they are now rare or absent. This is shown in a new study that uses centuries-old Swedish newspapers to reconstruct past distribution patterns.
As blood stem cells age, their lysosomes become overactive and damaged, triggering inflammation and weakening the body’s ability to regenerate healthy blood and immune cells. By calming this cellular “overdrive,” researchers restored the stem cells’ youthful function,
The largest-ever survey of physicists from around the world—released today—shows a distinct lack of consensus across many of physics's most important questions, from the nature of black holes and dark matter, to the still-incomplete unification of Einstein's theory of gravity
With plastic pollution at an all-time high, the need for biodegradable materials has never been higher. Most packaging is "single use" and is made from sources, like natural gas, that take hundreds of years to decompose in the environment. This is greatly contributing to the
Beneath the tropical trees of southern Mexico, enormous shoals of sulfur mollies blanket the water surface of toxic sulfur springs, where survival depends on collective defense against relentless attacks from predatory birds. The tiny fish survive attacks of birds through
Male primates may be larger than females partly because of pressure from rival groups, not just competition with males inside their own group.
