The Fight to Return An Iconic Skull to Zambia  

The town of Kabwe sits about 70 miles north of Zambia's capital, Lusaka, as the crow flies. Just over 200,000 people live in this major transportation crossroads. Like most of this south-central African nation, Kabwe is perched on a high and vast plateau, a land of red soils dotted with shrubby legumes and canopies of small, spindly miombo trees. Kabwe's story is defined in part by a mine that opened in the early 1900s after rich deposits of lead and zinc were discovered on the edge o...

Snapshot: Close-up With a Human Teardrop  

Tears often leave our faces feeling (and tasting) salty, but a closer look reveals the intricate patterns they can leave behind. Norm Barker, director of pathology photography at Johns Hopkins University School of Medicine, focused his microscope on a human teardrop, using a lighting technique to enhance contrast. Barker saw that as it started to dry, the salt and other substances in the teardrop bunched together and crystalized in these intricate, snowflakelike shapes. The picture ran

Astronomers Spot a Supermassive Black Hole Bouncing Jets Across its Galaxy  

Supermassive black holes lurk in the hearts of every large galaxy. Some blast out jets that can spill into its host galaxy or even beyond. The energy carried by the jets is deposited in the surrounding material, playing a crucial role in the evolution of the galaxy and, in extreme cases, other galaxies nearby. And thanks to recent observations of the famous galaxy Cygnus A with the Chandra X-ray Observatory, astronomers have gotten a closer glimpse at just how those jets work — and how th...

Ancient Sri Lankans Figured Out How to Sustainably Hunt Monkeys and Squirrels  

Some 45,000 years ago, the tropical rainforests of Sri Lanka teemed with dangerous plants and lacked big game, yet people made a life there. Our key to success in that seemingly inhospitable region? It was monkeys and squirrels, researchers say — or rather, our ability to catch them. "These animals are difficult to catch and suggest a certain level of sophistication in terms of hunting strategies," said Patrick Roberts, an archaeologist at the Max Planck Institute for the Science o...

A Philosopher Asked Physicists: 'What is a Black Hole?'  

Ask a dozen physicists what a black hole is, and you may get a dozen different answers - at least if those physicists are from different sub-fields. But new philosophy research suggests that may be okay, and may even lead to more interesting findings for black holes in the future. Such is the conclusion of Erik Curiel, who asked many different physicists across a range of research fields how they defined a black hole. Curiel works at the Munich Center for Mathematical Philosophy at Ludw...

Researchers Trace the Origins of Thousands of Ancient European Megaliths  

(Inside Science) - New research suggests that megaliths -- monuments such as Stonehenge created from large rocks during the Stone and Copper Ages in Europe -- owe their origins to a mysterious culture from northwest France with advanced seafaring technology. Roughly 35,000 megaliths are known throughout Europe, including standing stones, stone circles and megalithic tombs. Most megaliths date from 4500 to 2500 B.C., are concentrated in coastal areas along the Atlantic and Mediterranean ...

Physicists Finally Discover Why Grapes Ignite in the Microwave  

Consider the humble grape. Small, spheroid, with pleasantly taut skin, leaving a burst of sweetness on the tongue. Hardly a fruit you'd need to defend yourself against. Put a gently touching pair in the microwave, though, and the inoffensive fruit turns into a literal firecracker. Within just a few seconds, microwaved grapes will begin sparking as if electrified, and in some cases they'll even produce a flash of plasma bright enough to make the microwave glow from the inside out.

Valentine cards are filled with expressions of unequivocal adoration and appreciation. That's fitting for the holiday set aside to express love and reaffirm commitment to one's romantic partner. But what if there's more going on below the surface of these adoring declarations? How might thoughts and feelings that people are not even aware of shape their romantic relationships?

Why Do We Forget Things? It May Make The Mind More Efficient  

In the quest to fend off forgetfulness, some people build a palace of memory. It's a method for memorizing invented in ancient times by (legend has it) the Greek poet Simonides of Ceos, more recently made popular by multiple best-selling books (and the "mind palace" of Benedict Cumberbatch's Sherlock Holmes). Memory palaces provide imaginary architectural repositories for storing and retrieving anything you would like to remember. Sixteen centuries ago, St. Augustine spoke of ...

NASA Declares 'Mission Complete' For Opportunity Rover  

On January 24, 2004, the Opportunity rover sent back its first signal from the Red Planet. That marked the start of a 90-day planned mission for the six-wheeled, golf cart-sized rover. Fifteen years later, the rover's mission has finally ended, NASA announced today. Its longevity and discoveries are a testament to Opportunity's design and construction. The rover ultimately sent back more than 200,000 raw images and traveled a total of 28 miles (45 kilometers), farther than a standard ...

Reprogrammed Human Pancreatic Cells Treat Diabetes in Mice  

Nearly 10 percent of Americans have diabetes, a chronic condition where the body does not process sugar. Diabetics either do not make enough insulin — a hormone that acts like a key to let sugars into cells to use for energy — or cells stop responding to insulin. As a result, sugar builds up in the bloodstream leading to high blood sugar. Over time, high blood sugar can give rise to nerve damage and heart disease among other complications. Now researchers have reprogrammed human cells...

In those with the disease, however, irisin levels are depleted. Boosting irisin levels through exercise, then, might be a way to stave ...

Scientists Finally Confirm A Big Theory About Solar System Formation  

Planets, stars, and black holes all grow by consuming material from a spinning disk. While these disks may differ in size, they're all mostly dependent on the mighty force of gravity, which keeps them spinning around the central mass. Gravity lets small clumps grow into bigger clumps. But it's not enough to pull the whole disk into the middle in one giant clump, because angular momentum is pulling those clumps away from the center as they spin. That's a good thing, because it means that t

Marijuana May Not Hurt Sperm Counts Finds A Surprising Study  

In a surprise find, researchers discover smoking pot may not hinder sperm counts. According to a new study, men who had smoked marijuana at some point in their lives had higher sperm counts than men who had never smoked weed. The finding contrasts previous research showing regular cannabis use lowers sperm numbers. "These unexpected findings from our study highlight that we know too little about the reproductive health effects of cannabis and, in fact, of the health effects in general t...

Melting Ice Sheets Will Really Mess With a Fundamental Ocean Current  

Researchers have updated their predictions for what melting ice sheets will do to the planet within the next century. By 2100, the shrinking Antarctic and Greenland ice sheets will raise sea levels by nearly 10 inches. The influx of water will disrupt an ocean current vital to our weather, with dangerous consequences. "We're dealing with a very delicately balanced system," said Nicholas Golledge, a climate scientist at the Victoria University of Wellington in New Zealand, who led t...

The First CubeSats Ever to Visit Mars Have Gone Silent  

When NASA's InSight mission reached Mars last year, it wasn't alone. It was accompanied by two tiny satellites called CubeSats, or in this case, MarCO, for Mars Cube One. They were the first CubeSats ever to visit the Red Planet. The pair, nicknamed EVE and WALL-E, after Pixar's fictional robots, relayed information from InSight's descent. But their real mission was simply to show off their abilities so far from home and prove that such small missions - the total MarCO program only c...

Charon's Icy Surface Erupted From an Underground Ocean  

While New Horizons is exploring new targets, researchers are still working on the mountains of data it returned in 2015 from its visit to Pluto and its moon Charon. Charon is Pluto's largest companion, and like Pluto, it has a complicated, icy surface dotted with mountains and canyons. Large parts of Charon's surface appear to have been resurfaced in the past, leading to theories of an underground ocean that could have erupted long ago. New Horizons' best views of Charon were of its sid...

Astronomers Map a Black Hole Using 'Echoes' of Light  

Black holes pepper our universe, but like their name implies, most are invisible — until something happens to change that. That something is often material flowing into the black hole. And in March 2018, one such previously invisible black hole flared to life when a flood of matter fell inward, allowing astronomers to spot and track the event, ultimately mapping out the region close to a black hole in finer detail than ever before. That work, published January 9 in Nature, was le...

New Material Strengthens Like Muscles, Could Lead to Smarter Prosthetics  

(Inside Science) -- Researchers from Japan have come up with a way to encourage materials to grow stronger over time, like the muscles in our body. The new technique could allow engineers to design adaptable and healable materials for a wide range of applications. When we lift weights in the gym, the mechanical stress causes our muscle fibers to rip and tear, but this damaging action actually allows the fibers to regrow stronger afterwards. In contrast, nonliving materials such as rubber
