Semen frozen back in 1968 has been used to impregnate dozens of Merino ewes, resulting in healthy lambs. The Australian scientists who made it happen say it’s the oldest sperm ever used to produce offspring.
The ability to sense the Earth’s magnetic field—a trait known as magnetoreception—is well documented among many animals, but researchers have struggled to show that humans are also capable of the feat. Until now.
Nearly 25 years ago, the Pathfinder spacecraft explored a suspected floodplain on Mars. Unbeknownst to NASA at the time, the waters that long ago carved Pathfinder’s landing site spilled out from a previously undocumented inland sea nearby, new research shows.
Sadly, David Bowie was wrong about spiders on Mars, despite this exciting new image of what appears to a gigantic blue tarantula on the Martian surface. In reality, the false-color picture shows a series of trails produced by Martian dust devils. The photo is one of many captured by Europe’s ExoMars Trace Gas Orbiter,…
Humans couldn’t always easily produce “f” and “v” sounds, according to a surprising new study. The reason we can now enjoy words like “flavor” and “effervescent,” say the researchers, has to do with changes to the ancestral human diet and the introduction of soft foods—a development that altered the way we bite, and…
Prehistoric Britons traveled impressive distances to attend celebrations at monumental sites like Stonehenge, according to new research. Incredibly, many of them brought their pigs along with them for the journey—an impressive feat, considering some participants came from hundreds of miles away.
Archaeologists in Germany have unearthed some 400 artifacts dating back to a Nazi massacre in which hundreds of forced laborers were executed during the closing phases of World War II.
During the Apollo missions, NASA smartly set aside some lunar materials knowing future scientists would likely be better equipped to analyze them. Now, nearly 50 years later, the space agency is giving a select group of researchers the extraordinary opportunity to study these unopened and untarnished samples.
Dating back more than 12,000 years, this extraordinary example of rock art features a scene involving birds and humans—a rarity for the Paleolithic Period on several accounts.
Evidence of an unusually strong solar storm that hit Earth in 660 BCE has been detected in Greenland ice cores—a finding which shows we still have lots to learn about these disruptive events.
Earlier this week, NASA’s Solar Dynamics Observatory (SDO) captured a strange series of images in which the Moon appears to go rogue, crossing the Sun as usual but then briefly pausing to change direction. No, it’s not a sign of cosmological armageddon, but an optical illusion familiar to astronomers.
SpaceX’s new commercial astronaut capsule, the Crew Dragon, has completed its first test flight, falling into the Atlantic Ocean on Friday morning.
By combining data from the Hubble and Gaia space telescopes, an international team of astronomers has come up with the most accurate estimate yet of our galaxy’s mass.
NASA astronauts Anne McClain and Christina Koch will make history on March 29 by becoming the first all-women team to perform a spacewalk, which they’ll do outside the International Space Station.
The area immediately above our planet where most of our satellites live might seem like an inexhaustible place, but it’s not. Low Earth orbit is quickly filling up with all sorts of junk, and the potential for a disaster has never been greater. Here’s how laws and international treaties can help—and why we need to…
An air-to-air imaging technology developed by NASA has resulted in the first images ever taken of interacting shockwaves produced by in-flight supersonic jets. The new images, in addition to being beautiful, will help NASA design jets capable of producing gentle rumbles instead of loud sonic booms when breaking the…
Archaeologists working at a 15th-century site in Peru have unearthed the remains of 137 children and 200 llamas in what’s now considered the largest mass child sacrifice known from the New World—and possibly of all time.
The United States puts more people in prison than any other country in the world, yet little is known about the ways this sad reality impacts the immediate family members of those who are incarcerated. An alarming new study is revealing the extent of the issue, showing that 45 percent of all Americans have had a…
Antarctica is huge, stretching nearly 3,500 miles at its widest extent. Despite its enormous size, however, the frozen continent features a paltry amount of habitable space—a limited resource that humans have claimed as their own to the potential detriment of the local wildlife, as new research points out.
