Head Injuries Can Rewire Whole-Brain Networks in Mice, Important New Maps Reveal

Posted by in categories: mapping, neuroscience

We know the brain changes after traumatic injury, and now we have maps from mice showing what that change looks like.

A team of scientists has traced connections between nerve cells throughout the entire brain of mice, showing that distant parts of the brain become disconnected after a head injury.

The stunning visualizations of brain-wide connectivity could help scientists understand how a traumatic brain injury, or TBI, alters cross-talk between different cells and brain regions, first in mice and then in humans.

Mind-Bending Physics Reveals Electrons Travel in “Lanes” While Moving Along Quantum Wires

Posted by in categories: particle physics, quantum physics

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

Meta’s AI Takes an Unsupervised Step Forward

Posted by in category: robotics/AI

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.

Methane converted into methanol at room temperature — just add light

Posted by in categories: climatology, materials

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.

Off-grid hydrogen generation technology for on-demand power

Posted by in categories: energy, sustainability, transportation

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.
