More than 125 of these curious soccer ball-sized glass spheres hang near the floor of the Mediterranean Sea. Even though they're deep underwater, they're keeping a constant vigil for neutrinos, particles that may be evidence of dark matter, supernovae, and neutron stars far off in intergalactic space. Eventually, the Cubic Kilometer Neutrino Telescope (KM3NeT) will consist of 6,000 spheres suspended across one cubic kilometer of seawater. Often, neutrino detectors are located deep underground because the Earth itself helps isolate the instrument from background radiation and cosmic rays so the neutrinos are more easily spotted. From Scientific American:
“Perhaps one or two neutrinos in a million will interact with quarks inside the nucleus of either hydrogen or oxygen” in the water, says the project's physics and software manager, Paschal Coyle of the Marseille Particle Physics Center. “Because the cosmic neutrinos possess very high energy, the result of such interactions is the release of a charged particle that travels very fast.”
In fact, it travels through the water faster than light can, producing an effect Coyle likens to an optical equivalent of the Concorde jet's sonic boom. Researchers can determine the original neutrinos' energy and direction using the faint light released—so-called Cherenkov radiation—picked up by the undersea sensors.
Richard Branson’s Virgin Orbit failed on its first rocket launch attempt, which took place out of the Mojave Spaceport in Southern California.
Repeating the word “fuck” actually can reduce your experience of pain, according to a new study by Keele University researchers. The psychologists ran an experiment in which subjects underwent a cold pressor test, a common method to pain threshold and tolerance by immersing your hand in freezing cold water for a minute.

Floating out of your body and looking down on it. The story of your life flashing by before your eyes. Seeing a bright light at the end of a dark tunnel. These are just two of the most common experiences that people report after a near-death experience (NDE). For some people, NDEs are a transformative […]
Just as in almost any industry that seeks high-demand, well-trained workers, certification often becomes key. For project managers, that means anyone who’s serious about serving in that role with a respected company knows they’re going to need the seal of approval in one of the field’s most recognized methodologies before they stand much of a […]
Popping a new battery in a smoke detector or adding salt to your water softener are easy fixes. But if you run into trouble or a necessary repair in a cramped, tight place, sometimes with no obvious fix or easy access, it can be a pretty frustrating exercise. Since flying blind is the absolute worst, […]
Firing up the engines each morning and attacking the day with gusto and purpose can feel like a mighty tall order sometimes. We’ve all been there. But on those sluggish, why-don’t-I-just-stay-here-in-bed-all-day kinda days, it might just take a rational, calming, reassuring nudge to make it happen. No matter what it takes to keep you motivated […]
