Living skin can now be 3D-printed with blood vessels included

Posted by in categories: 3D printing, biotech/medical, engineering

Researchers at Rensselaer Polytechnic Institute have developed a way to 3D print living skin, complete with blood vessels. The advancement, published online today in Tissue Engineering Part A, is a significant step toward creating grafts that are more like the skin our bodies produce naturally.

“Right now, whatever is available as a clinical product is more like a fancy Band-Aid,” said Pankaj Karande, an associate professor of chemical and and member of the Center for Biotechnology and Interdisciplinary Studies (CBIS), who led this research at Rensselaer. “It provides some accelerated wound healing, but eventually it just falls off; it never really integrates with the host .”

Mayo Clinic Minute: What you need to know about stroke

Oct. 29 is World Stroke Day. Sometimes called a brain attack, stroke is the second leading cause of death worldwide and the fifth leading cause of death in the U.S. Men and women are at risk of a stroke, but women are more likely to have – and die – of a stroke than men. Dr. Kara Sands, a Mayo Clinic neurologist, says stroke kills twice as many women as breast cancer. The good news is that strokes are preventable, treatable and beatable.

Smaller Is Better: Lightweight Face Detection For Smartphones

Posted by in categories: internet, mobile phones, robotics/AI, security, surveillance

Although mobile devices were not designed to run compute-heavy AI models, in recent years AI-powered features like face detection, eye tracking, and voice recognition have all been added to smartphones. Much of the compute for such services is done on the cloud, but ideally these applications would be light enough to run directly on devices without an Internet connection.

In this spirit of “smaller is better,” Shanghai-based developer “Linzai” (GitHub user name @Linzaer) recently shared a new lightweight model that enables real-time face detection for smartphones. The “Ultra-Light-Fast-Generic-Face-Detector-1MB” is designed for general-purpose face detection applications in low-power computing devices and is applicable to both Android and iOS phones as well as PCs (CPU and GPU). The project has garnered a whopping 3.3k Stars and over 600 forks on GitHub.

Facial recognition technology is widely applied in security monitoring, surveillance, human-computer interaction, entertainment, etc. Detecting human faces in digital images is the first step in facial recognition, and an ideal face detection model can be evaluated by how quickly and accurately it performs.

How Silicon Valley billionaires claim they’ve discovered the secret to everlasting life

Posted by in category: life extension

The scene last weekend at the Westgate, a Las Vegas mega resort, was like many others in Sin City. Alongside the one-armed bandits and craps tables, around 1,000 people milled around a mega convention centre. Many would have been close to pensionable age, and came from all corners of the Earth. But all the attendees at the event, RAADfest, were pursuing something out of the ordinary: immortality.


‘Immortalists’ say they have discovered how to slow and perhaps even reverse the ageing process — but is that really a good thing?

How a Man’s Fecal Transplant Turned Fatal

Posted by in category: biotech/medical

The first person known to die as a result of a fecal transplant is a 73-year-old man who developed a fatal infection with antibiotic-resistant bacteria that were in the donor’s stool sample.

News of the man’s death surfaced in June; he was one of two patients in separate clinical trials who became ill after receiving fecal transplants from the same donor, Live Science previously reported.

Could the key to fighting antibiotic resistance in humans be found in the blood of the deadly Komodo dragon?

Posted by in categories: biotech/medical, health

Bacterial infections that are resistant to treatment by our existing antibiotics are a huge threat to human health — and an enormous challenge for medicine. Scientists are exploring one fascinating line of research: compounds modeled after those found in the blood of the fearsome Komodo dragon.

Sheldon Breiner, 82, Dies; Used Magnetism for Explorations

Posted by in categories: government, military

Ever since the compass was invented, perhaps about 2,000 years ago, humans have used Earth’s magnetic field to guide them. Many ages later, Sheldon Breiner devised ways to use magnetism to guide him to things that might otherwise never have been found — like sunken ships, a lost city and colossal basalt heads buried underground.

Dr. Breiner, a geophysicist, inventor and serial entrepreneur, started a company called Geometrics in 1969 that built sophisticated magnetometers, which measure magnetic fields. (A compass is probably the most simple example of one.) He then discovered how to use them to detect objects by observing the way the objects affect the magnetic fields that surround them.

Dr. Breiner had started employing rubidium magnetometers to detect seismic activity along the San Andreas Fault when he was studying geophysics at Stanford University. In time he harnessed magnetometers to search for mineral and oil deposits deep underground; find hidden weapons; locate skiers lost in avalanches; and help the government track down sunken submarines and a hydrogen bomb that had fallen into the ocean after a B-52 bomber collided with a refueling jet over Spain in 1966.

Big Bang theory: Scientists discover what happened BEFORE the Big Bang

Posted by in category: cosmology

THE Big Bang theory has long been accepted as scientific fact as an explanation of the universe came into being – but it has always begged the question ‘what happened before the big bang?’
