The answer is hard to pin down, in part because it happens so rarely, but it’s clearly a hell of a lot. In an email, Jack James, the editor-in-chief of the Journal of Caffeine Research, says that overdose for adults requires roughly 10 grams of caffeine. (People typically ingest just 1 to 2 mg/kg of caffeine per beverage.) A 2005 Forensic Science International article on two fatal caffeine overdoses in New Mexico pegs the figure closer to about 5 grams–an amount that would still require drinking more than 6 gallons of McDonald’s coffee....

Most recently, positive publicity for pot has emerged via a group of Italian and British researchers experimenting with tetrahydrocannabinol—the main active ingredient in marijuana. More commonly known as THC (because, let’s face it, anyone under its influence isn’t going to be able to get that octosyllabic word out of his mouth), the compound and its related compounds have proven themselves effective antibacterial agents. A team of scientists led by Giovanni Appendino at the University of Eastern Piedmont tested the five most common cannabinoids (a group of substances that are structurally related to THC) and found each one to be effective against several common multiresistant bacterial strains....

We’re so used to discarding things—clothes, shoes, gadgets—after mere months of use because so many products are designed badly or manufactured cheaply. Fight back against that degradation by buying stuff that will actually last. Your grandparent’s cast iron pan could get passed down to you just like a parent’s 1980′s-era flannel could be—and you could be that parent or grandparents someday. You just have to buy things that will outlast you....

A 2019 study in Public Health Reports found that the majority of the surveyed population say they scour the web to find the source of their ailments, with 69 percent saying that the internet is their first destination for medical and health information. However, only 30 to 40 percent of people reported finding actually useful resources and guidance in their search journeys, while others say they grew frustrated with the process....

But many people also upload clips of copyrighted material to YouTube in a way that enhances or transforms the content into something new, such as critiques: …parodies: …or Autotuned remixes: This is called “fair use,” and it is legal in the United States. And now YouTube will do more than allow it: it will actually provide some financial support to defend video creators who have made videos that qualify for “fair use” exemptions, yet who are nonetheless sued by other copyright owners for infringement....

But global demand for sand is high, and supplies—in the form of pits and offshore dredging sites—are limited, leading to conflicts and even violence in some areas. “People are being killed over sand in India,” says Mette Bendixen, a physical geographer at the Institute of Arctic and Alpine Research of the University of Colorado, Boulder. “This is really something that gives me the goosebumps—it’s a huge, huge conflict mineral in some areas, and the world doesn’t really know....

Helmet manufacturer Riddell knows a bit about football and military helmets. Founder John Riddell helped invent the World War II suspension helmet and his company currently has an 84 percent market share in the NFL and approximately 40 percent in college. Asked by military personnel in February to improve the Army’s Advanced Combat Helmet (ACH), Riddell provided a prototype inner liner in just six months. Riddell was instructed to maintain the outer ballistic shell of the ACH and the offset distance from the head to the inside of the shell (3/4 inch)....

An international team of researchers uncovered a rare set of three human lung tissue specimens dating between 1900 and 1931, preserved in the Berlin Museum of Medical History and the Natural History Museum in Vienna, Austria. By analyzing these samples, researchers were able to complete the genome of the flu virus from early on in the 1918 pandemic. When they compared it to today’s H1N1 swine flu, they found that every element of H1N1’s genome could be directly descended from that initial strain....

IOActive researcher Barnaby Jack demonstrated this capability at a security conference in Melbourne, according to Australia’s SC Magazine. He used a laptop to send a series of 830-volt shocks to a remote pacemaker, and used some sort of unclear “secret function” the pacemakers possess, which could be used to activate all pacemakers and implantable defibrillators within a 30-foot radius. The devices would give up their serial numbers, which would allow the would-be assassin to breach their firmware and upload nefarious malware that could spread to other pacemakers like a virus....

In fact, researchers have found that sleep plays a vital role in the functioning of nearly every organ system in the body. At the same time, medical conditions, a busy schedule, and even the simple unavoidable act of aging constantly challenge the number of hours we allow ourselves. But that begs the question: how much sleep do we actually need? And can we train ourselves to need less? First, let’s talk about that eight hour figure that gets tossed around....

The story of the lunar module ascent stages goes hand in hand with the story of NASA doing seismic experiments on the Moon. Seismology, measuring how shock waves move across and through a planetary body, can tell scientists a lot about that body’s surface and internal structure. Seismologists do this on Earth by studying earthquakes, so NASA decided to do the same type of investigation on the Moon. Lunar seismology experiments reached the Moon with each Apollo landing mission as part of the Apollo Lunar Surface Experiment Package or ALSEP....

Earlier this year, NASA announced plans for the station’s eventual retirement in 2031, but it’s unlikely that the 450-ton lab will meet a quick demise. Once operations end, most dead satellites drift out of orbit and eventually burn up in Earth’s atmosphere. However, most of the ISS will sink into Point Nemo, a remote area of the Pacific Ocean so far from land that many scientists refer to it as a “space cemetery,” after the number of spacecraft laid to rest in the watery grave....
