As the US prepares to return humans to the Moon this decade, one of the biggest dangers future astronauts will face is space radiation that can cause lasting health effects, from cataracts to cancer and neurodegenerative diseases.
Though the Apollo missions of the 1960s and 1970s proved it was safe for people to spend a few days on the lunar surface, NASA did not take daily radiation measurements that would help scientists quantify just how long crews could stay.
This question was resolved Friday after a Chinese-German team published in the journal Science Advances the results of an experiment carried out by China’s Chang’E 4 lander in 2019.
“The radiation of the Moon is between two and three times higher than what you have on the ISS (International Space Station),” co-author Robert Wimmer-Schweingruber, an astrophysicist at the University of Kiel told AFP.
“So that limits your stay to approximately two months on the surface of the Moon,” he added, once the radiation exposure from the roughly week-long journey there, and week back, is taken into account.
This is the DroneGun Tactical made by Droneshield that provides a safe countermeasure against a wide array of drone models. The DroneGun takes down unwanted drones by shooting radio frequencies instead of bullets. It’s a one-man operated rifle used as a military defense that has an effective range of one mile.
Meet Nemesis, one of the many endangered great hammerhead sharks that spends her winters in Bimini, The Bahamas. This interactive 3D project was a close collaboration between Angela Rosenberg, President of ANGARI Foundation and Captain of R/V ANGARI, Duncan Irschick, Professor at UMass Amherst and Director of Digital Life with CG artist Jeremy Bot and Casey Sapp, CEO of VRTUL.
Footage was collected during R/V ANGARI’s Expedition 33 in Bimini with Casey Sapp’s custom underwater multi-camera system to collect views of Nemesis swimming from all angles. The videos provided Digital Life modelers with the necessary imagery and data to create a high resolution and accurate animated 3D model.
The completed interactive 3D shark model is part of Digital Life’s “ark” of living organisms, which serves as an invaluable resource for educators, scientists and conservationists.
This work would not have been possible without the financial and field support of several donors.
This is the GermFalcon airplane disinfection system by Dimer UVC Innovations that uses Ultra-violet “C” light (UVC) to instantly kill 99.99% of bacteria, viruses, and superbugs on any exposed surface. The process is efficient, affordable, and highly-effective especially in hard-to-reach areas on a plane. Plus, it sanitizes all surfaces without any toxic after-effects, unlike chemical disinfectants.
Anyone who has heard anything about Primoz Roglic, the current leader of the Tour de France, knows about his former career leaping off snowy mountains. His life in winter sports comes up so often that the words “former ski jumper” might as well be attached to his name on the road to Paris.
Haven’t you heard? There’s a bicycle shortage in the United States as people’s discomfort with taking public transportation is met with their need to exercise. But as always, with impeccable timing, Lamborghini is here with a solution — a limited-edition street bike. Yours for merely the price of a cheap new car.
Lamborghini teamed up with Canadian-Dutch bicycle company Cervélo Cycles to create the “ultra-limited edition” (their words) Cervélo R5 Automobili Lamborghini Edition. It wears a livery that you’ll recognize from the Lamborghini Aventador SVJ and has only Italian-made components as accessories.
Only 63 examples of the bike will be made. It’s available now and carries a price tag of $18,000 — or about $3,000 more than a new Mitsubishi Mirage.
Started reading “Deep.” A birthday present from Patrick Brown
It’s stories about freediving: No fins, scuba, nothing. Not 20’ deep either. Hundreds! Their bodies actually change from the pressure. Stay tuned for updates as I’m reading.
“They freedive because it’s the most direct and intimate way to connect with the ocean. During that three minutes beneath the surface (the average time it takes to dive a few hundred feet), the body bears only a passing resemblance to its terrestrial form and function. The ocean changes us physically, and psychically.”
This is the next-gen floating house by Miami-based Arkup that promotes “avant-garde life on the water.” Equipped with electric propulsion and four hydraulic spuds, Arkup’s houseboat can actually lift itself out of the water – thanks to its customized self-lifting barge and it’s totally stable at anchor.
