Rats fed a sugar syrup early in life develop an unusual gut microbiome that seems to worsen the rodents’ memories by changing the way their brains work.
The NASA’s Space Launch System rocket booster segments that will help power NASAs first #Artemis mission around the Moon are getting ready for launch. NASA’s Exploration Ground Systems team is prepping them for assembly and integration activities ahead of stacking with the rocket: http://go.nasa.gov/3d9M6F7
The rocket booster segments that will help power NASA’s first Artemis flight test mission around the Moon arrived at the agency’s Kennedy Space Center in Florida on Monday for launch preparations.
All 10 segments for the inaugural flight of NASA’s first Space Launch System (SLS) rocket and Orion spacecraft were shipped by train from Promontory, Utah. The 10-day, cross-country journey is an important milestone toward the first launch for NASA’s Artemis program.
“The arrival of the booster segments at Kennedy is just the beginning of the SLS rocket’s journey to the pad and onward to send the Orion spacecraft to the Moon,” said NASA Administrator Jim Bridenstine. ” Artemis I will pave the way toward landing the first woman and the next man on the surface of the Moon in 2024 and expanding human exploration to Mars.”
Many say that the Cold War didn’t accomplish anything but it did heat up the world of weapon development. The United States and Communist Russia went head to head in the race to develop the most powerful nuclear weapon. However, sometimes the most powerful weapon is not the most efficient one, so the United States took a different approach.
The result was the development of a small, powerful, portable nuclear warhead, the W54. The small nuke earned the nickname “Davey Crockett” was intended for by ground troops and operated via rocket launcher.
“The test seen up top had a yield equivalent of 18 tons of TNT, coming from a warhead that weighed only a little more than 50 pounds. Later, a variant of the warhead saw use in the Special Atomic Demolition Munition, also known as the backpack nuke.”
On a cold March night last year in Portsmouth, England, an entirely new type of aircraft flew for the first time, along a dimly lit 120-meter corridor in a cavernous building once used to build minesweepers for the Royal Navy.
This is the Phoenix, an uncrewed blimp that has no engines but propels itself forward by varying its buoyancy and its orientation. The prototype measures 15 meters in length, 10.5 meters in wingspan, and when fully loaded weighs 150 kilograms (330 pounds). It flew over the full length of the building, each flight requiring it to undulate up and down about five times.
Flying in this strange way has advantages. For one, it demands very little energy, allowing the craft to be used for long-duration missions. Also, it dispenses with whirring rotors and compressor blades and violent exhaust streams—all potentially dangerous to people or objects on the ground and even in the air. Finally, it’s cool: an airship that moves like a sea creature.
On Friday afternoon, Tesla CEO Elon Musk and Director of Policy and Government Affairs Craig Hulse landed in Tulsa, OK, for a meeting with local officials. Musk’s trip comes amidst Tesla’s highly anticipated announcement about the site of the Cybertruck Gigafactory, the electric car maker’s upcoming manufacturing plant for its unique all-electric pickup.
Musk and Hulse were welcomed by Gov. Kevin Stitt and Secretary of Commerce Sean Kouplen, as well as the property owner of a plot of land that the city is offering to the electric car maker. Images shared by the Gov. Stitt show Musk and local officials conversing in the middle of a massive plot of land. The meetup seemed to be private and simple, though the governor highlighted that he still believes that Tulsa is the perfect place for Tesla’s next vehicle production plant.
A company wants to use an advanced balloon to fly customers from Earth’s surface in Alaska to the highest reaches of the planet’s atmosphere.
Florida-based startup firm Space Perspective plans to use the Pacific Spaceport Complex in Kodiak to serve as one of the launch sites for the vehicle, called the Spaceship Neptune, The Anchorage Daily News reported on Sunday.
The balloon rides will be manned by a flight crew taking eight passengers in a pressurized capsule suspended beneath a hydrogen balloon the size of a football stadium.
NASA’s newest spacecraft concept looks like it belongs in a steampunk convention more than a distant moon, but that’s exactly where it’s supposed to be headed.
Steam power sounds like a relic of the Victorian era only glamorized by steampunk culture, but NASA is developing SPARROW (Steam Propelled Autonomous Retrieval Robot for Ocaen Worlds), a new steam-powered robot concept that could potentially unearth life on moons like Enceladus or Europa. Sure, our space agency might be known for the most cutting-edge technology, but even that could face potential disaster on frozen moons whose surfaces could be perilous. This relatively simple contraption is capable of doing things more complex robots can’t.
The first black US Drone company has created a new drone training program to help people re-tool their careers in a post-Covid-19 world.
Scientists at Johns Hopkins Medicine have found types of cells in the brain that are most susceptible to inherited genetic variants linked to schizophrenia. As a result, their work reveals a shortlist of the variants that most likely impact disease risk.
Details of the scientists’ analysis, published April 17, 2020, in Genome Research, compared human genetic studies with data on how DNA is folded in mouse cells, including a diversity of brain cells.
“Every common disease has a major genetic component at its root,” says Andrew McCallion, Ph.D., professor of genetic medicine at the Johns Hopkins University School of Medicine. “Studying genomes across human populations helps us find the genetic landmarks that are linked to disease, but these often don’t give us the biological insight that pinpoints the cells in which that variation acts to impact disease risk.”
A glove that translates sign language into speech in real time has been developed by scientists — potentially allowing deaf people to communicate directly with anyone, without the need for a translator.
A glove that translates sign language into speech in real time has been developed by scientists — potentially allowing deaf people to communicate directly with anyone, without the need for a translator.
The wearable device contains sensors that run along the four fingers and thumb to identify each word, phrase or letter as it is made in American Sign Language.
Those signals are then sent wirelessly to a smartphone, which translates them into spoken words at a rate of one word per second.
