Hydrogen power is here to stay. How do we convince the public that it’s safe?

Posted by in category: energy

Via World Economic Forum


It’s a clean and viable replacement for fossil fuels in transport, energy storage and power-to-gas applications. But public doubts around hydrogen safety are contributing to the delay in its adoption around the world.

Powerful new telescope joins the search for possible laser pulses from aliens

Posted by in category: alien life

Statistically, it’s pretty much a given that alien life is out there somewhere, whether that’s Martian microbes or highly intelligent life beaming comms through the cosmos. While the Curiosity rover is poking around in the dirt for the former, the Breakthrough Listen initiative is searching for the latter. Now, a new telescope array has joined the hunt, scanning the skies for flashes of laser light that alien civilizations might be giving off.

Scientists discovered a new species of tiny sharks that glow in the dark

Posted by in category: futurism

Sharks are known to stalk and sniff out prey before they attack. But all this newly discovered shark species has to do is glow in the dark, and the prey comes to them.

The 5 1/2-inch American Pocket Shark is the first of its kind to be discovered in the Gulf of Mexico, according to a new Tulane University study. It’s less fearsome than it is wondrous.

Scientists stumbled upon a teeny male kitefin shark in 2010 while studying sperm whales in the Gulf. It wasn’t observed again until 2013, when National Oceanic and Atmospheric Administration (NOAA) researcher Mark Grace found it in a pool of less luminous specimens.

Will the X3 ion thruster propel us to Mars?

Posted by in category: space travel

X3 is a powerful ion thruster that could one day propel humans beyond Earth. The thruster was successfully tested few months ago, and could be selected by NASA as a crucial component of propulsion system for future Mars missions.

X3 is a Hall-effect thruster—a type of ion thruster in which the propellant (most commonly xenon) is accelerated by electric and magnetic fields. Such thrusters are safer and more fuel efficient than engines used in traditional chemical rockets. However, they currently offer relatively low thrust and acceleration. Therefore, engineers are still working to make them more powerful.

Nearly 31.5 inches (80 centimeters) in diameter and weighing around 507 lbs. (230 kilograms), X3 is a three-channel nested thruster designed to operate at power levels up to 200 kW. The thruster is jointly developed by the University of Michigan (U-M), NASA and the U.S. Air Force. The project is funded through NASA’s Next Space Technologies for Exploration Partnership (NextSTEP).

Regenerative Medicine: Fat-derived Stem Cells — Medical Frontiers-JAPAN Live & Programs

Posted by in categories: biotech/medical, life extension

This 2-part series on “Regenerative Medicine” shows how it is possible to replace lost or damaged body parts by using human cells. Surviving a disease such as cancer can leave scars, both physical and emotional. Whether it’s due to a mastectomy or radiation therapy, scars are hard to avoid. Fat-derived stem cells can help patients return close to their original state, providing peace of mind. We also look at the benefits of using oil to balance the amount of fat in a body.

The military’s future body armor could be as thin as 2 atoms

Posted by in categories: military, particle physics, weapons

If you’ve been a grunt, then you probably have a love-hate relationship with body armor. You love having it in a firefight — it can save your life by stopping or slowing bullets and fragments — but you hate how heavy it is — it’s often around 25 pounds for the armor and outer tactical vest (more if you add the plate inserts to stop up to 7.62 mm rounds).

It’s bulky — and you really can’t move as well in it. In fact, in one firefight, a medic removed his body armor to reach wounded allies, earning a Distinguished Service Cross.

Imagine if the body armor were just another part of your clothes, like a light jacket. Imagine not having to haul around those extra 30 pounds. Well, troops may not have to imagine much longer. According to a release from the Advanced Science Research Center at the City University of New York, body armor could soon have the thickness of just two atoms. This is due to how graphene acts under certain conditions.

Physicists Just Discovered The First Elusive Candidate For a 3D Quantum Spin Liquid

Posted by in categories: particle physics, quantum physics

Physicists in the US have discovered a material that could qualify as the first known three-dimensional example of a quantum spin liquid — an exotic theoretical phase of matter.

Quantum spin liquids were first predicted by scientists back in the 1970s. While researchers have studied them for decades, these phases largely remain a theoretical concept, although that’s not the same as saying they don’t exist.

To confuse you further, quantum spin liquids aren’t actually liquids, but a kind of solid, magnetic matter that exhibits a strange form of behaviour at the subatomic particle level, specifically in terms of its electrons.
