‘Nanomagnetic’ computing can provide low-energy AI, researchers show

Researchers have shown it is possible to perform artificial intelligence using tiny nanomagnets that interact like neurons in the brain.

The new method, developed by a team led by Imperial College London researchers, could slash the of (AI), which is currently doubling globally every 3.5 months.

In a paper published today in Nature Nanotechnology, the international team have produced the first proof that networks of nanomagnets can be used to perform AI-like processing. The researchers showed nanomagnets can be used for ‘time-series prediction’ tasks, such as predicting and regulating insulin levels in .

Scientists engineer a bacteria to produce a drug used to treat Parkinson’s disease

The results of the study could lead to new treatment options. In a groundbreaking new study published in the journal Nature on Thursday, researchers have compared the brain cells of patients who had died from either Parkinson’s disease or dementia to people unaffected by the disorders and found which brain cells are responsible for both conditions.

A team of researchers has created a bacteria that can produce a steady and consistent source of medicine inside a patient’s gut, suggesting the possibility for genetically edited bacteria to be an efficient Parkinson’s disease treatment.

Moreover, the researchers have shown via preclinical experiments that the novel treatment technique is not only safe and well-tolerated, but it also reduces side effects that can occur when other treatments are utilized.

An engineered probiotic

For long, scientists have been experimenting with ways of engineering bacteria to fit our needs for decades. The new research is the latest example of that.

Scientists engineer new tools to electronically control gene expression

Researchers, led by experts at Imperial College London, have developed a new method that allows gene expression to be precisely altered by supplying and removing electrons.

This could help control biomedical implants in the body or reactions in large ‘bioreactors’ that produce drugs and other useful compounds. Current stimuli used to initiate such reactions are often unable to penetrate materials or pose risk of toxicity—electricity holds the solution.

Gene expression is the process by which are ‘activated’ to produce new molecules and other downstream effects in cells. In organisms, it is regulated by regions of the DNA called promoters. Some promoters, called inducible promoters, can respond to different stimuli, such as light, chemicals and temperature.

Carbon-Neutral Gas Is Coming That Cleans Our Air

EVs are pretty widely accepted as the newer, greener path of the automobile. Sometimes, they’re pitched as a solution to climate change that we can all buy at a dealership. But some haven’t given up on conventional motors yet. Porsche is perhaps the best example. The brand has been exploring synthetic, carbon-neutral fuels for a while now, and being able to run our Porsche 911 on green fuel sounds like a win-win to us.

But it appears that another company might have figured out how to do it better. The firm claims that it can produce a carbon-neutral fuel that’ll also clean the air around us. It sounds like a magic cure-all for personal vehicle emissions, but the technology is solid.

Using radar to monitor burn victims and babies? It’s now possible

University of Sydney scientists have achieved a technology breakthrough with potentially life-saving applications—all using an improved version of radar.

Traditionally, is associated with airport control towers or military fighter jets, but a new, highly sensitive radar developed at the University of Sydney takes this technology into the human range.

Called advanced photonic radar, the ultra-high-resolution device is so sensitive it can detect an object’s location, speed, and/or angle in millimeters as opposed to meters. This could enable usage in hospitals to monitor people’s vital signs such as breathing and heart rate.

Spontaneous Magnetic Reversal of Monster Black Hole Sparks Enigmatic Outburst

NASA’s Swift Observatory Tracks Potential Magnetic Flip of Monster Black Hole A rare and enigmatic outburst from an active galaxy 236 million light-years away may have been sparked by a magnetic reversal, a spontaneous flip of the magnetic field surrounding its central black hole. In a comprehen.

A device, created at Stevens Institute of Technology, uses millimeter-wave imaging — the same technology used in airport security scanners — to scan a patient’s skin to detect if they have skin cancer. Millimeter-wave rays harmlessly penetrate about 2mm into human skin, so the team’s imaging technology provides a clear 3D map of scanned skin lesions.
