The World’s Smallest Nuke- Detonation Clip

Posted by in categories: military, nuclear weapons

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.

No Propeller? No Problem. This Blimp Flies on Buoyancy Alone

Posted by in categories: energy, transportation

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.

Elon Musk accepts Oklahoma Gov. invite, visits site of proposed Tesla factory in Tulsa

Posted by in categories: Elon Musk, government, policy, sustainability, transportation

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.

You may soon be able to ride to the edge of space from Alaska in a Balloon

Posted by in category: space travel

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.

This steampunk-looking robot could be NASA’s newest way to explore frozen alien moons

Posted by in categories: robotics/AI, space travel

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.

Scientists develop method to reveal the cell types most affected by genetic variation

Posted by in categories: biotech/medical, genetics, neuroscience

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 , including a diversity of .

“Every common 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 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.”

High-tech glove translates sign language into speech in real time

Posted by in categories: mobile phones, wearables

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.

Some Blind People Can Still See, And Their Brains Could Help Explain Consciousness

Posted by in category: neuroscience

Imagine being completely blind but still being able to see. Does that sound impossible? Well, it happens.

A few years ago, a man (let’s call him Barry) suffered two strokes in quick succession. As a result, Barry was completely blind, and he walked with a stick.

One day, some psychologists placed Barry in a corridor full of obstacles like boxes and chairs. They took away his walking stick and told him to walk down the corridor.

Astronaut Christina Koch On Her Journey From Space To A Nation In Lockdown

Posted by in category: space

Astronaut Christina Koch spent a record 11 months in space, the longest spaceflight of any woman. She returned to Earth in February and is just completing her NASA-mandated readjustment period. What’s life like when you leave a space station, only to be confined in your own home under lockdown?
