After 180 years, new clues are revealing just how general anaesthesia works in the brain

Posted by in categories: biotech/medical, neuroscience

Over 350 million surgeries are performed globally each year. For most of us, it’s likely at some point in our lives we’ll have to undergo a procedure that needs general anaesthesia.

Even though it is one of the safest medical practices, we still don’t have a complete, thorough understanding of precisely how anaesthetic drugs work in the brain.

In fact, it has largely remained a mystery since general anaesthesia was introduced into medicine over 180 years ago.

Segway unveils futuristic new electric bike and arguably electric motorcycle

Posted by in categories: law, sustainability, transportation

Segway has taken to the Consumer Electronics Expo (CES) in Las Vegas to unveil a pair of new electric two-wheelers. The first is an electric bicycle called the Xafari, while the latter is a borderline electric motorcycle known as the Xyber.

Both bikes are ostensibly categorized as electric bicycles in the US, fitting within the legal definition of the category. The Xafari even feels like it fits nicely under the e-bike classification, though the Xyber seems to carry a bit more Sur Ron vibes than Schwinn vibes, if you get the idea.

Any way you slice them, both bikes mark a major push deeper into the industry for Segway as the company continues to expand in the micromobility category.

Mapping the Milky Way’s Magnetic Field in 3D

Posted by in categories: mapping, particle physics, space

We are all very familiar with the concept of the Earth’s magnetic field. It turns out that most objects in space have magnetic fields but it’s quite tricky to measure them. Astronomers have developed an ingenious way to measure the magnetic field of the Milky Way using polarized light from interstellar dust grains that align themselves to the magnetic field lines. A new survey has begun this mapping process and has mapped an area that covers the equivalent of 15 times the full moon.

Many people will remember experiments in school with iron filings and bar magnets to unveil their magnetic field. It’s not quite so easy to capture the magnetic field of the Milky Way though. The new method to measure the field relies upon the small dust grains which permeate space between the stars.

The grains of dust are similar in size to smoke particles but they are not spherical. Just like a boat turning itself into the current, the dust particles’ long axis tends to align with the local magnetic field. As they do, they emit a glow in the same frequency as the cosmic background radiation and it is this that astronomers have been tuning in to.

New Circuit Boards can be Repeatedly Recycled

Posted by in categories: chemistry, computing, sustainability

A recent United Nations report found that the world generated 137 billion pounds of electronic waste in 2022, an 82% increase from 2010. Yet less than a quarter of 2022’s e-waste was recycled. While many things impede a sustainable afterlife for electronics, one is that we don’t have systems at scale to recycle the printed circuit boards (PCBs) found in nearly all electronic devices.

PCBs — which house and interconnect chips, transistors and other components — typically consist of layers of thin glass fiber sheets coated in hard plastic and laminated together with copper. That plastic can’t easily be separated from the glass, so PCBs often pile up in landfills, where their chemicals can seep into the environment. Or they’re burned to extract their electronics’ valuable metals like gold and copper. This burning, often undertaken in developing nations, is wasteful and can be toxic — especially for those doing the work without proper protections.

A team led by researchers at the University of Washington developed a new PCB that performs on par with traditional materials and can be recycled repeatedly with negligible material loss. Researchers used a solvent that transforms a type of vitrimer — a cutting-edge class of sustainable polymers — to a jelly-like substance without damaging it, allowing the solid components to be plucked out for reuse or recycling.

Vitamin D Alters Mouse Gut Bacteria to give Better Cancer Immunity

Posted by in categories: bioengineering, biotech/medical, health

Researchers at the Francis Crick Institute, the National Cancer Institute (NCI) of the U.S. National Institutes of Health (NIH) and Aalborg University in Denmark have found that vitamin D encourages the growth of a type of gut bacteria in mice which improves immunity to cancer.

Reported today in Science, the researchers found that mice given a diet rich in vitamin D had better immune resistance to experimentally transplanted cancers and improved responses to immunotherapy treatment. This effect was also seen when gene editing was used to remove a protein that binds to vitamin D in the blood and keeps it away from tissues.

Surprisingly, the team found that vitamin D acts on epithelial cells in the intestine, which in turn increase the amount of a bacteria called Bacteroides fragilis. This microbe gave mice better immunity to cancer as the transplanted tumours didn’t grow as much, but the researchers are not yet sure how.

Einstein completed his theory of general relativity in 1915 when he was 37 years old. What did he do for the remaining 40 years of his life? He continued developing his masterwork of course! Feeling that his theory was incomplete, Einstein pursued a unified field theory. Though he ultimately failed, the ideas he came up with were quite interesting. I have read a lot of old Einstein papers in the past weeks and here is my summary of what I believe he tried to do.
