This Is What it Looks Like When a Black Hole Shreds a Star

Posted by in categories: cosmology, evolution

When a star wanders too close to a black hole, immense gravitational forces begin to rip it apart in an epic cosmic slaying called a “tidal disruption event.” Some of the star’s mass is flung outward into space, while the rest is drawn in, triggering a powerful flare that showers the sky with x-rays.

Using NASA’s Chandra X-ray Observatory and other telescopes, a team of astronomers has now pieced together one such astronomical feasting frenzy. The event in question, appropriately named “ASASSN-14li,” was spotted near the center of PGC 043234, a galaxy that lies 290 million light years from Earth.

98% Of Drugs Never Make It To The Brain, But This Method Could Change That

Posted by in categories: biotech/medical, neuroscience

Treating the brain isn’t like the rest of the body. Your blood-brain barrier shields it; filtering the blood to ensure nothing untoward makes it through. This protection is normally a good thing, but it becomes a problem if you want to deliver therapeutic drugs through it. This method could be a solution.

Smuggling therapeutics

Many diseases like Parkinson’s and Alzheimer’s disease are extremely difficult to treat. Only very specific molecules can make it through the brain’s secure barrier, and most drugs don’t make the cut. This poses a challenge when you want to treat disease inside the brain, and so efforts have been focused on finding a way to overcome this. New research has now demonstrated a way of treating Parkinson’s disease with a surgical treatment that opens up a small route to bypass the barrier; essentially a smuggling hatch into your brain.

Key to longevity? Sharing DNA info is necessary to extend human life, Google exec says

Posted by in categories: biotech/medical, genetics, life extension

The much pursued fountain of youth can become a reality if humans agree to share their DNA information, according to Google Ventures’ CEO Bill Maris, who has warned that “we’re all going to die” earlier if we keep our genetic codes secret.

Maris, who aims to digitize DNA, stressed during a Wall Street Journal technology conference in California that our genomes “aren’t really secret,” urging those protective of their genetic information to loosen the reins a bit.

Noting that genetic material is constantly left lying around in public, Maris addressed those who remain nervous about the digitization of DNA. “What are you worried about?” he said on Tuesday, adding that a person could easily gather information by fishing a used cup out of the trash and taking it to a lab for analysis.

Quantum Theory: ‘Spooky Action at a Distance’ confirmed

Posted by in categories: encryption, general relativity, physics, quantum physics, science

In one of my first articles for Lifeboat,* I provided an experimental methodology for demonstrating (or proving) the instantaneous ‘communication’ between quantum entangled particles. Even though changes to one particle can be provably demonstrated at its far away twin, the very strange experimental results suggested by quantum theory also demonstrate that you cannot use the simultaneity for any purpose. That is, you can provably pass information instantly, but you cannot study the ‘message’ (a change in state at the recipient), until such time as it could have been transmit by a classical radio wave.

Now, scientists have conducted an experiment proving that objects can instantaneously affect each other, regardless o the distance between them. [continue below]

Robot taught to navigate with simulated brain cells

Posted by in categories: neuroscience, robotics/AI

But it may offer advantages over these systems, which are often confused by changes to an environment. And researchers hope that the work will not only allow a more efficient way for robots to navigate but also provide neuroscientists a better understanding of place cells, grid cells and cognitive maps.

The First Robot Operated Hospital in North America Has Finally Opened

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

The $1.7 billion investment has finally opened its doors to the public, and the robots are ready to provide patients with a medical experience that’s truly revolutionary.

Hailed as the first fully digital hospital in North America, the Humber River Hospital in Toronto, CA finally opened its doors to the public on October 18. In addition to being equipped with the most advanced technologies, robots currently man several areas of the facility. This includes the radiology area where they facilitate the X-Ray procedure and the chemotherapy area where they mix, prepare, and monitor the drugs being administered to the patients. Before the drugs get to the patients, each package is checked and scanned thoroughly through an information management system to make sure that the patients get the correct treatment. These automated robots will also be assisting the health care staff by carrying and delivering medical supplies and food for patients.

This smart pavement is giving pedestrians access to free Wi-Fi

Posted by in categories: business, internet

A footpath in the UK has been equipped with free Wi-Fi coverage, with manholes, on-street cabinets, and other ‘street furniture’ being used to broadcast the signal, which reaches maximum speeds of 166 Mbps and can be accessed from up to 80 metres (260 feet) away.

For the time being, this is a very small-scale scheme: the connected street has been set up in the market town of Chesham, home to some 21,000 people, about 50 km outside of London. As you might expect, it’s a promotional stunt on the part of Virgin Media, but the company says it’s committed to improving public Wi-Fi access across the country, and will be using feedback from the trial in Chesham to help inform its future plans.

“The unlimited Wi-Fi service is available to residents, businesses, and visitors passing through the centre of Chesham,” explains the Virgin Media team. “The service even covers parts of Lowndes Park — Chesham’s 36-acre park space.”
