Breathtaking Image Shows Powerful Magnetic ‘Ropes’ Surrounding The Whale Galaxy

Posted by in category: space

Sometimes you just have to stand back in awe at the beauty of the Universe – and that’s absolutely the case with this image from the National Radio Astronomy Observatory (NRAO), which captures the side view of a spiral galaxy know as the Whale Galaxy.

But if you look closer, the stunning picture also shows something else: the magnetic ‘ropes’ around the edges of the galaxy’s disc.

These filaments, like cosmic strands of hair, show the galaxy’s magnetic field extending into its halo.

Blood Test to Diagnose Brain Cancer in Development

Posted by in categories: biotech/medical, robotics/AI

Brain cancer remains challenging to diagnose, due to nonspecific symptoms and a lack of cost-effective tests. A new blood test that uses attenuated total reflection (ATR)-Fourier transform infrared (FTIR) spectroscopy in conjunction with machine learning technology, may help advance the detection of brain cancer.

The patented technology, developed by a team at the University of Strathclyde, uses infrared light to produce a “bio-signature” of a blood sample and applies artificial intelligence to check for the signs of cancer.

The research is published in Nature Communications in a paper titled, “Development of high-throughput ATR-FTIR technology for rapid triage of brain cancer.

Tiny Electric Thrusters from Phase Four, Accion Could Go Interplanetary

Posted by in category: space travel

Circa 2019


Electric thrusters for spacecraft are increasingly shrinking, and could prove key for new space missions. And, according to two novel space tech companies, Phase Four and Accion Systems, they might even go interplanetary.

Conventional rockets that rely on chemical reactions “are a great way to generate a lot of thrust, but they are very inefficient when it comes to generating thrust given the amount of propellant they carry,” Simon Halpern, founder and CEO of space propulsion company Phase Four in El Segundo, California, told Space.com. “That’s why launching even a small satellite requires a gigantic multistory rocket.”
