A new study from the University of Cambridge reveals that electrons can simultaneously possess different energy levels.

Electrons, one of the most fundamental components of our universe, still hold a few secrets that puzzle modern scientists. Since the 1920s, physicists have worked to try and unravel the workings of these negatively charged particles, and how they behave in different situations. Now, research conducted at the University of Cambridge has shed new light on a pair of key factors–the spins and charges of electrons–revealing even more about their unique behavior.

Background: Spin and Charge

In the 1920s, scientists conducted several experiments that revealed electrons possess multiple spins. One of these, the Stern-Gerlach experiment, involved a beam of silver atoms directed at an uneven magnetic field. The magnetic field split the beam in two, revealing two different spins for the electron.

Meta researchers believe that self-supervised learning is a necessary prerequisite for AI systems that can build “world models” and can therefore begin to gain human-like faculties such as reason, common sense, and the ability to transfer skills and knowledge from one context to another.

In the quest for human-level intelligent AI, Meta is betting on self-supervised learning.

Science fiction amazes us with futuristic technology and weapons, but many like the laser pistol, raygun, or lightsaber seem high-tech versions of old tech. Are such weapons possible and if so, could they have a role in future warfare?

Scientists have developed an efficient new way to convert methane into methanol at room temperature. The technique could help reduce greenhouse gas emissions and provide a cleaner way to make key products.

While carbon dioxide gets most of the attention, it’s not the only greenhouse gas changing the Earth’s climate. Methane is emitted in smaller amounts but is 34 times more potent, so reducing its levels remains a priority. Excess methane from industrial processes is often burned off, but that produces CO2.

A commonly sought alternative is to convert methane into methanol, which can be used to make a range of products like fuels, plastics and construction materials. The problem is, the conversion process usually requires high temperatures and pressures, which makes it energy-intensive.

Spotted: Although relatively expensive to produce at present, and with storage often cited as a concern, green hydrogen fuel production is increasing. A naturally occurring and superabundant element, hydrogen is popular for several reasons, including the ability to produce it using renewable energy sources. And now, Element 1’s modular, grid-independent hydrogen generation technology is making the fuel even more accessible.

Designed to efficiently convert methanol to hydrogen to electricity, the technology supports both hydrogen fuel cell vehicles and electric vehicles. The company’s catalytic reactor heats a methanol and water feedstock mix before sending it through a membrane purifier for almost 100 per cent fuel cell grade hydrogen.

Because the modular system produces the fuel as needed, the risk of combustion is nearly eliminated, and specialty storage facilities are redundant. This is because the only material that needs to be stored and transported is the methanol and water feedstock. The hydrogen is then produced on-site. Element 1 provides both small and large-scale solutions, as well as a mobile version specifically for refuelling electric vehicles on the go.

NASA has set an aggressive launch target for its following the of the SLS rocket that will carry the flight to space. In an interview with , Jim Free, associate administrator with the agency’s Explorations Systems Development program, said this week NASA is working toward an August 23rd to September 6th launch window for Aretmis 1. “That’s the one we’re targeting,” Free told the outlet. “We’d be foolish not to target that right now. We made incredible progress last week.”

For those keeping track, NASA recently the earliest it could get Artemis 1 in space following a successful fueling test of the SLS was between July 26th and August 10th. Instead, NASA selected the second earliest launch window it had open to it.

Before the flight can get underway, technicians must complete final preparations on the SLS rocket, including replacing a seal that led to a hydrogen leak during its June 20th test. NASA began rolling the SLS back to the Kennedy Space Center’s Vehicle Assembly Building, where staff will work on the launch vehicle, on. “I don’t think we’re stretching ourselves to get there,” Free said. “We’re probably pushing ourselves a little bit, but we’re not going to do something stupid.”

We’re about to have an entirely new perspective on the universe.

The James Webb Space Telescope will release its first high-resolution color images on July 12. One of those images “is the deepest image of our universe that has ever been taken,” said NASA Administrator Bill Nelson during a news conference on Wednesday.

“If you think about that, this is farther than humanity has ever moved before,” Nelson said. “And we’re only beginning to understand what Webb can and will do. It’s going to explore objects in the solar system and atmospheres of exoplanets orbiting other stars, giving us clues as to whether potentially their atmospheres are similar to our own.”
