This nice; however, China’s Quantum Sat. announcement is the big news this morning.
Black holes might not be the bottomless pits we think they are.

Engineers at the University of California, Berkeley have created the very first dust-sized wireless sensors that may be implanted within the body. This is bringing technology closer to the day that technologies such as the Fitbit will be able to monitor internal nerves, muscles and organs all in real time.
These devices do not require batteries and may also be able to stimulate nerves and muscles opening up doors for electroceuticals to treat disorders including epilepsy and stimulate the immune system or lower inflammation.
The neural dust is implanted in the muscles and peripheral nerves of rats and is unique due to its use of ultrasound. It holds the ability to both power and read measurements. Ultrasound technology is already very thoroughly developed for the care of hospice patients and ultrasound vibrations are able to penetrate just about everywhere within the human body making them much more useful than radio waves.

Imagine a future where we can treat diabetes or autoimmune disorders with an electrical zap delivered by a device no larger than a speck of dust.
The device, implanted through microsurgery, sits silently on a single nerve bundle, monitoring electrical signals sent out by the brain to itself and various organs in the body.
When it detects a problem — a rogue misfire, or a shift in activity patterns — the device powers up, sending out counter-pulses to correct the signal. In this way, it keeps your body running smoothly and disease at bay. No pills. No injections. No pain.

Researchers from Polytechnique Montréal, Université de Montréal and McGill University have just achieved a spectacular breakthrough in cancer research. They have developed new nanorobotic agents capable of navigating through the bloodstream to administer a drug with precision by specifically targeting the active cancerous cells of tumours. This way of injecting medication ensures the optimal targeting of a tumour and avoids jeopardizing the integrity of organs and surrounding healthy tissues. As a result, the drug dosage that is highly toxic for the human organism could be significantly reduced.
This scientific breakthrough has just been published in the prestigious journal Nature Nanotechnology in an article titled “Magneto-aerotactic bacteria deliver drug-containing nanoliposomes to tumour hypoxic regions.” The article notes the results of the research done on mice, which were successfully administered nanorobotic agents into colorectal tumours.
“These legions of nanorobotic agents were actually composed of more than 100 million flagellated bacteria — and therefore self-propelled — and loaded with drugs that moved by taking the most direct path between the drug’s injection point and the area of the body to cure,” explains Professor Sylvain Martel, holder of the Canada Research Chair in Medical Nanorobotics and Director of the Polytechnique Montréal Nanorobotics Laboratory, who heads the research team’s work. “The drug’s propelling force was enough to travel efficiently and enter deep inside the tumours.”

Anti-inflammatory drug mefenamic acid completely reversed memory loss and brain inflammation in mice genetically engineered to develop symptoms of Alzheimer’s disease and amyloid beta-induced memory loss, a team led by David Brough, PhD, from the University of Manchester has discovered.
The non-steroidal anti-inflammatory drug (NSAID) drug targets an important inflammatory pathway called the NLRP3 inflammasome, which damages brain cells, according to Brough. This is the first time a drug has been shown to target this inflammatory pathway, highlighting its importance in the disease model, Brough said.

Recent findings indicating the possible discovery of a previously unknown subatomic particle may be evidence of a fifth fundamental force of nature, according to a paper published in the journal Physical Review Letters by theoretical physicists at the University of California, Irvine.
“If true, it’s revolutionary,” said Jonathan Feng, professor of physics & astronomy. “For decades, we’ve known of four fundamental forces: gravitation, electromagnetism, and the strong and weak nuclear forces. If confirmed by further experiments, this discovery of a possible fifth force would completely change our understanding of the universe, with consequences for the unification of forces and dark matter.”
The UCI researchers came upon a mid-2015 study by experimental nuclear physicists at the Hungarian Academy of Sciences who were searching for “dark photons,” particles that would signify unseen dark matter, which physicists say makes up about 85 percent of the universe’s mass. The Hungarians’ work uncovered a radioactive decay anomaly that points to the existence of a light particle just 30 times heavier than an electron.

Most NYC subway riders are pretty blasé when panhandlers hit them up for cash between stations. When a panhandler announced he was collecting funds to build a time machine, riders chuckled at the odd request—until another man boarded the train and announced he was the inventor’s future self. He implored them not to give any money because time travel will ruin everything.
It sounds just like that X-Files episode (“Synchrony”) where a scientist travels from the future to stop his younger self from making the cryobiological compound that will one day enable time travel. But it’s actually an elaborate prank by Improv Everywhere:
For our latest mission, we staged an elaborate time travel prank on a New York City subway car with four sets of identical twins. A man enters a subway car and announces he is raising money to complete his time machine. At the next stop, his future self enters to try to talk him out of it. More and more time travelers convene on the subway car as the train rolls along, surprising the random commuters caught up in the middle.
