Spending hours in front of a computer can be bad for your health and lead to conditions like repetitive strain injury or carpal tunnel syndrome. Which peripherals you choose can make a huge difference, and that’s why you should consider upgrading to an ergonomic mouse.
Ride-sharing company Uber has teamed up with Walgreens to help customers get appointments for a COVID-19 vaccine at the same time they schedule a ride to the pharmacy. With this new feature, users can browse vaccination appointment time slots at Walgreens in the Uber app, claim the time they want, then continue on to book a ride for the appointment. … Continue reading
Even after we die, some of our brain cells can experience one last and large momentary burst of life, new research out Tuesday suggests. The study found evidence that certain “zombie genes” in our brain cells are active more frequently soon after death, which causes some cells to immensely expand for hours. The…
Concerns over the potential harms of 5G technology are overblown, according to two large new reviews of research recently published by scientists in Australia. Both found no clear evidence that the type of radiofrequency energy used by 5G mobile networks poses any danger to human health.
The thyroid, a small butterfly-shaped organ on the front of the throat, produces hormones that are vital for health — and, sadly, the same organ is prone to various issues ranging from autoimmune hypothyroidism to thyroid cancer. Various types of damage and diseases can cause thyroid hormone production to drop, a problem currently treated with synthetic hormones. Though many people … Continue reading
Researchers at the University of Buffalo are bringing a science fiction trope to life with their new 3D printing method, which can produce a synthetic hand in under 20 minutes. The rapid printing technology minimizes cellular damage and deformation, making it one of the most viable options for 3D printing human organs.
A surreal YouTube video shows the 3D printing method in action, and it looks like something out of a movie—it’s just so quick and simple. A machine dips into a shallow solution of yellow goo and pulls out a fully-formed synthetic hand in just under 20 minutes. Researchers at the University of Buffalo say that conventional printing methods would take 6 hours to produce the same hand.
The new printing method relies on stereolithography or photo-solidification, the same process used in resin printing. Basically, scientists use light to selectively cure a hydrogel solution into a desired shape. Stereolithography works 10 to 15 times faster than regular bioprinting methods, so scientists can provide a continuous supply of biogel to their model, limiting environmental exposure and mistakes.
Biogel stereolitography is already suited to print cellular models with blood-vessel networks, although the technology is currently limited to centimeter-sized models. Scientists should be able to scale up the method, though, which will be essential for printing human-sized organs. Who knows, in the future, every hospital could be equipped with a biogel stereolithography printer to manufacture replacement organs on the fly, eliminating the need for human-to-human organ transplants.
Pent-up clubgoers descended on Amsterdam’s Ziggo Dome on Sturday for a dance party enabling scientists to study how large events could be held as COVID-19 begins to subside. Around 1,300 people—all who tested negative for COVID-19—hit the dancefloor wearing electronic tags to track their interactions. — Read the rest
Psychedelic microdosing has proven popular, particularly in industries that require creativity and quick thinking. Microdosers report a variety of alleged benefits resulting from taking minuscule quantities of psychedelics like LSD, but the largest placebo-controlled study of its kind has found that these effects are ‘likely’ the result of the placebo effect. Psychedelic microdosing, which involves taking sub-perceptual doses of psychedelic … Continue reading
Yet another vaccine is now part of our arsenal of weapons against the covid-19 pandemic. On Saturday, the Food and Drug Administration granted an emergency use authorization (EUA) to the one-dose shot developed by Johnson & Johnson. It joins the two-dose mRNA vaccines developed by Modern and Pfizer/BioNTech.
