The microscopic processes involved in human fertilization are a difficult thing to convey visually, but a group of scientists, using Star Wars as their inspiration, have managed to do just that, creating a highly entertaining and informative video—while accidentally stumbling upon a new scientific discovery in the…

Scientists Just Found the Perfect Spot to Build an Underground Colony on the Moon Scientists Just Found the Perfect Spot to Build an Underground Colony on the Moon

For years, scientists have wondered if dark, crater-like features on the lunar surface might be entrances to giant caverns carved long ago by flowing lava.

Researchers from Sweden made headlines last week after claiming to have found the Arabic characters for “Allah” and “Ali” woven into Viking burial costumes. The discovery suggested a more intimate cultural relationship between the Vikings and the Arab world, but some experts are now questioning key assertions made by…

Scientists Document 'Opportunistic' Alligators Eating Sharks Scientists Document 'Opportunistic' Alligators Eating Sharks

It’s a dog-eat-dog world out there, or in the case of the southeastern United States, it’s an alligator-eat-shark kind of a world, according to an unsettling new study from Kansas State University scientists.

Compared to Wolves, Dogs Are Absolutely Terrible at Cooperation Compared to Wolves, Dogs Are Absolutely Terrible at Cooperation

Humans and dogs have a long history of working together, leading to the assumption that the collaborative abilities of dogs are the result of domestication. New research suggests this isn’t the case, and that wolves are far better at cooperation than their domesticated cousins, at least when they’re cooperating with…

Intense Methane Rainstorms Carve Titan’s Icy Surface Intense Methane Rainstorms Carve Titan’s Icy Surface

If you were soaring above the surface of Saturn’s largest moon, Titan, you’d see mountains, rivers, lakes, and seas, but you might also run into a monsoon-like rainstorm. Severe weather doesn’t happen very often on Titan, but new research suggests than when it does, the skies unleash torrents of liquid methane that…

The Historic Race to the South Pole May Have Been Influenced by a Freak Warm Spell The Historic Race to the South Pole May Have Been Influenced by a Freak Warm Spell

In 1911, two teams—one from Norway and one from Britain—vied to become the first to reach the South Pole. Led by Roald Amundsen, the Norwegian team won the race, while all five members of Robert Falcon Scott’s Terra Nova Expedition perished on the return journey home. New research suggests Amundsen’s team may have…

Captive Orca Whales Are So Bored They're Destroying Their Teeth Captive Orca Whales Are So Bored They're Destroying Their Teeth

An investigation into the oral health of captive orca whales is raising serious concerns about the health and welfare of these majestic creatures. Out of boredom and frustration, many of the whales turn to chewing on concrete and steel tank surfaces, causing wear and tear that leads to further problems.

Watch SpaceX Launch and Land a Previously Used Rocket Live Right Here  Watch SpaceX Launch and Land a Previously Used Rocket Live Right Here 

Later today, SpaceX will launch a previously flown Falcon 9 rocket to a Geostationary Transfer Orbit (GTO), where it will drop off an EchoStar 105/SES-11 communications satellite. Following deployment, the rocket will attempt a landing on a droneship stationed in the Atlantic ocean. You can watch it live right here…

Close Encounter With Asteroid Will Test Earth's Early Warning System Close Encounter With Asteroid Will Test Earth's Early Warning System

Early tomorrow, a small asteroid will zip past Earth well inside the Moon’s orbit. NASA says poses no threat, but astronomers around the world will use the opportunity to test the international community’s ability to detect and track potentially dangerous objects.

Scorpions Can Tweak Their Venom in Response to Changing Threats Scorpions Can Tweak Their Venom in Response to Changing Threats

New research shows that some scorpions can tailor their venom depending on the task at hand, whether it be snatching its next meal or protecting itself against predators. It marks the first time that scientists have documented the ability of an animal to adjust the toxicity of its venom according to need.

Restored Prisoner’s Letter Uncovers Horrific Details of Life at Auschwitz Death Camp Restored Prisoner’s Letter Uncovers Horrific Details of Life at Auschwitz Death Camp

In 1944, Marcel Nadjari—a Greek Jew who was forced to remove bodies from the Auschwitz gas chambers—buried a letter in a forest near the camp.

What Filthy Old Birds Can Tell Us About Air Pollution What Filthy Old Birds Can Tell Us About Air Pollution

By analyzing sooty birds housed in museum collections, scientists have been able to track patterns of US air pollution over the last 135 years. As the new study shows, air at the turn of the 20th century was even dirtier than we thought—a finding that will now be used to improve our climate models.

Injectable ‘Elastic Glue’ Seals Wounds in Just 60 Seconds Injectable ‘Elastic Glue’ Seals Wounds in Just 60 Seconds

An innovative surgical glue developed by researchers from the United States and Australia seals wounds quickly and without the need for staples or stitches. The squirtable substance could eventually be used in surgeries and in emergency situations, though it still needs to be tested on humans.

That Time When Volcanic Eruptions Created a Temporary Atmosphere on the Moon That Time When Volcanic Eruptions Created a Temporary Atmosphere on the Moon

Aside from some floating dust, our Moon has absolutely no atmosphere to speak of. New research suggests this wasn’t always the case, and that long ago, an atmosphere briefly popped into existence as a result of intense volcanic activity.
