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.
