This total solar eclipse looked strangely golden — here’s why

Last week’s total solar eclipse offered more than a spectacular view. It also produced an unusual atmospheric effect that gave the Sun’s outer atmosphere a striking golden appearance. During a total solar eclipse, the Moon completely blocks the bright disk of the Sun, making the much fainter solar corona visible.…

More than 1,000 genetic switches reveal why female immunity is different

Women are diagnosed with autoimmune diseases far more often than men, and new research from the Garvan Institute of Medical Research and UNSW Sydney may help explain why. Autoimmune diseases occur when the immune system mistakenly targets the body’s own healthy tissues. Lupus, for example, can affect as many as…

Researchers reveal deeper workings of brain’s information hub

The human brain is continuously processing enormous amounts of information. Even something as familiar as driving requires several mental tasks at once. The brain must remember the route, recall how to control the vehicle, and respond to unexpected developments such as a road closure or shifting traffic conditions. A brain…

A mother’s age can shape her offspring without changing their DNA

A mother’s age can influence the physical traits and behavior of her offspring in humans and across many other animal species. Researchers refer to these changes as maternal age effects. Although the phenomenon is common throughout the animal kingdom, scientists are still working to understand the biological processes underlying it…

Coffee drinkers have less fat, more muscle, and surprising hormone differences

Coffee is consumed around the world every day, and earlier research has associated coffee drinking with a reduced risk of conditions including type 2 diabetes and cardiovascular disease. Scientists still do not fully understand the biological processes that might explain those connections. Now, new research from Finland suggests that regular…

Scientists turn probiotic bacteria into tiny drug factories for pancreatic cancer

Cancer immunotherapy has dramatically changed how doctors treat many forms of cancer, yet pancreatic cancer has remained particularly resistant to these advances. A major obstacle is the environment that develops around pancreatic tumors. These tumors often create a “cold” tumor microenvironment that blocks immune cells from launching an effective attack.…

Tiny quantum engines reveal useful energy hiding in “waste heat”

What counts as heat, and what qualifies as useful work when a machine is made from only an atom and particles of light? In emerging quantum technologies, questions like this bring together two branches of physics that were developed for very different purposes. Researchers at the University of Basel in…

Pollen has a surprising problem — and honeybees have found a way around it

New research led by the University of Oxford has uncovered an unexpected ability in bees. They can change how much they eat depending on the balance of essential amino acids in their food. This feeding behavior may protect them from consuming excessive amounts of certain amino acids when pollen does…

This 23-foot crocodylian may have ruled South America’s food chain

More than 10 million years ago, South America was home to an ecosystem filled with enormous animals and formidable predators. During the Miocene, a geological period that lasted for millions of years, a vast lake covered a large portion of the continent. Its waters supported giant turtles and crocodylians, while…

16 mummies and a dog reveal a hidden order inside an ancient Egyptian tomb

The Theban Necropolis, located across the Nile from Luxor, contains more than 400 tombs. In a new study published in Frontiers in Environmental Archaeology, researchers in Spain took a closer look at chamber three inside tomb TT 209 to understand how the burial space changed over time. The tomb was…

Tiny robots powered by light can hunt down and collect bacteria

Robots small enough to operate in the microbial world could give scientists a new way to directly handle objects that are impossible to manipulate by hand. These tiny machines are around 50 times smaller than the diameter of a human hair, bringing researchers closer to the long-pursued goal of interacting…

Scientists discover a natural Arctic cloud factory missing from climate models

Scientists have identified a previously unknown natural process in the Arctic that can cause the number of cloud-forming particles in the atmosphere to surge. The discovery could have important implications for cloud cover, how much sunlight is reflected back into space, and how the Arctic responds to future climate change.…

Scientists may have finally proved that “empty” space isn’t really empty

Astronomers may have found some of the strongest evidence yet for one of quantum mechanics’ strangest predictions: even apparently empty space can influence the way light travels. Known as ‘vacuum birefringence’, the phenomenon was predicted nearly 90 years ago by Werner Heisenberg, one of the pioneers of quantum mechanics. His…

Einstein’s biggest “mistake” came back — and changed cosmology forever

A little more than a century ago, Albert Einstein turned his attention from gravity itself to the fate of the entire universe. In 1917, shortly after developing his general theory of relativity, he began applying his new equations to cosmology. General relativity had transformed our understanding of gravity, so it…

A therapy that “rewrites” childhood memories can ease fear of failure
