How to Create a Black Hole Out of Thin Air

Posted by in category: cosmology

Black holes were thought to arise from the collapse of dead stars. But a Webb telescope image showing the early universe hints at an alternative pathway.

NH Bill Seeks to Ban Cloud Seeding and Other Forms of Atmospheric Geoengineering

Posted by in categories: engineering, geoengineering

Every legislative session is presented with too many bills and, in recent years, too slim of a majority to get the good ones to the Governor. But because we have so many new ideas, there are always some you might not expect, like legislation to ban weather modification.

To be clear, I’m not making fun of the bill or its sponsors. In a world where some folks can’t shut up about unnecessary “emissions” or pollutants in our atmosphere, this should play well on both sides of the aisle. New Hampshire House Bill 1,700 (HB1700).

Blood Test Uses Fragmentomics to Detect Liver Cancer

Posted by in category: biotech/medical

Another advantage of fragmentomics is that it requires much less blood than other liquid biopsy tests, she added.

The fragmentomics approach is also appealing because it requires only a blood draw, Dr. Greten noted, which is typically faster, easier to get, and less expensive than an ultrasound.

Fragmentomics is a next-generation liquid biopsy approach, said Dr. Velculescu. And it can potentially be used to detect other kinds of cancer, in addition to those the team has already studied, he added.

Stem cell injections could be the key to curing MS

Posted by in category: biotech/medical

Researchers are honing in on ways to halt the progression of MS and maybe even prevent it altogether:


From promising stem cell therapies to EBV vaccines, researchers are closer than ever to finding a cure for MS.

Cancer Treating Nano-Drones

A research team from UNIST has made a discovery that might revolutionize cancer treatment as we know it-new cell-engaging nano-drones that were designed to target and eliminate cancer cells selectively.

These tiny bots are called NK cell-engaging nano-drones (NKeNDs), and their success lies in their ability to engage natural killer (NK) cells, the body’s frontline defenders against cancer. Using NK cells in cancer treatment is not new, but what sets these nanodrones apart is their precision. They are engineered to zero in on cancer cells almost like guided missiles.

How the brain learns to deal with surprises

Posted by in category: neuroscience

How does the developing brain process surprising sounds and what changes as we grow up?


For children, the world is full of surprises. Adults, on the other hand, are much more difficult to surprise. And there are complex processes behind this apparently straightforward state of affairs. Researchers at the University of Basel have been using mice to decode how reactions to the unexpected develop in the growing brain.

Babies love playing peekaboo, continuing to react even on the tenth sudden appearance of their partner in the game. Recognizing the unexpected is an important cognitive ability. After all, new can also mean dangerous.

The Kessler Effect and how to stop it

Posted by in categories: robotics/AI, satellites

NASA space debris expert Don Kessler observed that, once past a certain critical mass, the total amount of space debris will keep on increasing: collisions give rise to more debris and lead to more collisions, in a chain reaction. So Clean Space is seeking not just to cut debris production from future ESA missions but to reduce the total mass of current debris, such as the robotic salvage of derelict satellites. The task is an urgent one: debris levels have increased 50% in the last five years in low orbit.
