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.
Elon Musk’s Neuralink rival Synchron has begun human trials of its brain implant that lets the wearer control a computer using thought alone.
The firm’s Stentrode brain implant, about the size of a paperclip, will be implanted in six patients in New York and Pittsburgh who have severe paralysis.

With the GPU industry finally stabilizing after two years of shortages and inflated costs, prices for graphics cards are finally approaching their MSRPs.
The team, part of Surrey’s research program in the exciting new field of quantum biology, have shown that this modification in the bonds between the DNA strands is far more prevalent than has hitherto been thought. The protons can easily jump from their usual site on one side of an energy barrier to land on the other side. If this happens just before the two strands are unzipped in the first step of the copying process, then the error can pass through the replication machinery in the cell, leading to what is called a DNA mismatch and, potentially, a mutation.
In a paper published this week in the journal Communications Physics, the Surrey team based in the Leverhulme Quantum Biology Doctoral Training Center used an approach called open quantum systems to determine the physical mechanisms that might cause the protons to jump across between the DNA strands. But, most intriguingly, it is thanks to a well-known yet almost magical quantum mechanism called tunneling—akin to a phantom passing through a solid wall—that they manage to get across.
The molecules of life, DNA, replicate with astounding precision, yet this process is not immune to mistakes and can lead to mutations. Using sophisticated computer modeling, a team of physicists and chemists at the University of Surrey have shown that such errors in copying can arise due to the strange rules of the quantum world.

The copper fangs of these feisty marine worms could inspire future sustainable manufacturing processes.
In this video we discuss, Science Fiction book, “Children of Time” By Adrian Tchaikovsky. It’s the best book I’ve read this year by a long shot! It’s about evolution, consciousness, humanity’s future, and more! Also SPIDERS!

The stars are officially aligned for NASA’s James Webb Space Telescope.
The extremely expensive space observatory has finished its alignment phase, with scientists confirming that it’s almost ready to kick off official scientific operations later this year.
In other words, the $10 billion telescope is on the home stretch, nearing its biggest milestone yet. NASA also released a slew of stunning new sample images taken by the telescope, showing the Large Magellanic Cloud, a small satellite galaxy of our Milky Way — stunning previews, hopefully, for a slew of imagery we’ll see from the ‘scope.
Admatec has steadily been increasing its 3D printing capabilities, taking its slurry-based digital light processing (DLP) process further. First it expanded from resins loaded with ceramic particles to those loaded with metal particles. It then increased the build volume of its Admaflex300 3D printer. Now, the company has introduced a new integrated debinding and sintering furnace with a larger work volume.
The majority of ceramic 3D printing processes rely on the use of a photopolymer slurry loaded with ceramic particles. Once printed, these green parts first go through a debinding process, in which the photopolymer material is removed, followed by sintering, causing the part to become fully dense.
Machines are learning things fast and replacing humans at a faster rate than ever before. Fresh development in this direction is a robot that can taste food. And not only it can taste the food, it can do so while making the dish it is preparing! This further leads to the robot having the ability to recognise taste of the food in various stages of chewing when a human eats the food.
The robot chef was made by Mark Oleynik, a Russian mathematician and computer scientist. Researchers at the Cambride University trained the robot to ‘taste’ the food as it cooks it.
The robot had already been trained to cook egg omelets. The researchers at Cambridge University added a sensor to the robot which can recognise different levels of saltiness.
