Astronomers have long had their eye on a group of stars that precariously circles just outside the supermassive black hole at the heart of our Milky Way galaxy. And, in a discovery announced by the European Southern Observatory on Thursday, scientists say they've finally spotted one of these stars as it travels through the black hole’s gravitational field. It's the first test of Albert Einstein's theory of general relativity near a supermassive black hole. The event, recorde ...read more

High winds are the norm at the center of the Milky Way. Astronomers have now clocked suns orbiting the galactic core at a staggering 3,000 miles (4,800 kilometers) per second. At this rate, Earth would complete its orbit around the sun in a mere three days. What lurks at the galaxy’s core that can accelerate stars to such speeds? Astronomers have considered various possibilities. Does the center of the galaxy harbor a tight cluster of superdense stellar remnants (neutron sta ...read more

Entrepreneurs are wired different than the rest of us. They’ll embrace huge financial risk to start a business despite statistics showing most startups fail. That chutzpa often gets tied to environmental factors, like how they were raised or where they went to college, or even to an X factor — something unknown but all-important that allows them to accept risk without flinching. Other studies have even hinted at a genetic component to risk-taking, or sensat ...read more

In an eyebrow-raising new paper, neuroscientists report that they had participants wear a ball gag while watching images of people in pain. The lucky participants in this neuro-bondage were all female BDSM submissives, and their brain activity in response to the painful pictures was recorded with EEG. Here's the article: Embodiment and Humiliation Moderation of Neural Responses to Others' Suffering in Female Submissive BDSM Practitioners And here's some of the stimuli (I assume they we ...read more

As luck would have it, Mars will remain engulfed in a colossal dust storm as it reaches opposition on July 27. The viewing conditions might be abysmal, but astronomers can at least take solace in a long-awaited Martian mystery being solved — where all of this dust is coming from. New research published in the journal Nature Communications revealed that the massive amounts of dust are tied to Mars’ Medusae Fossae Formation (MFF), the ...read more

Biting your tongue or cheek when chewing can ruin a tasty meal. But thankfully, mouth wounds heal up fast — faster than cuts on skin — and now scientists know why. According to new research published today in Science Translational Medicine, mouths are primed for healing. The find could help researchers transfer the mouth’s curative superpowers to make skin lesions heal faster too. Paper cuts, scraped knees and similar skin wounds take ab ...read more

Just imagine what you could do with a third arm. You could sip coffee and type an email. You could scratch your nose and play Call of Duty. You could solve the Rubik’s cube and conduct a symphony. You could play Ping-Pong and knit a sweater. Clearly, we could all use a third arm. Fortunately, giving us a hand with a third arm might be a promise science can deliver on, like, soon. That’s because engineers at the Advanced Telecommunications Research Instit ...read more

Astronomers have discovered a large underground lake of liquid water lurking just below the surface of Mars. The find could end a more than century-long debate over whether or not the Red Planet still has liquid water. The newfound lake stretches some 12 miles from end-to-end, and was discovered using a radar instrument called MARSIS on board the European Space Agency’s Mars Express spacecraft, which first reached Mars nearly 15 years ago. The results were published Wednesday ...read more

One thing that many people in the Pacific Northwest are holding their breath for is "The Big One" -- the next recurrence of a massive earthquake in the Cascadia Subduction zone. This earthquake could be greater than a magnitude 8 and cause immense damage to cities like Portland, Seattle and Vancouver. This hypothetical earthquake could even potentially triggering a tsunami that will cross the Pacific Ocean just like a similar temblor in 1700 did when waves washed ashore in Japan. It is a ser ...read more

If you're a fan of muscley men, listen up: those guns might come at the cost of a man's fertility. In this study (published in the journal Animal Behavior, because we ain't nothin' but mammals), the researchers report that physical strength in men, while seen as attractive by women, is also associated with "lower ejaculate quality." Boxer shorts, anyone? Perceived physical strength in men is attractive to women but may come at a cost to ejaculate quality "Studies of sexual selectio ...read more
