Sleep deprivation may speed up development of Alzheimer’s disease.

“Our main goal is to let patients control them as naturally as though they were their biological limbs,” says Professor Dario Farina from Imperial College.

A team of scientists from Imperial College London and the University of Göttingen have teamed up to create a ‘next generation’ bionic hand. This bionic hand is special because it uses artificial intelligence to improve its functionality.

Human lungs are coated with a substance called surfactant which allows us to breathe easily. When lung surfactant is missing or depleted, which can happen with premature birth or lung injury, breathing becomes difficult. In a collaborative study between Lawson Health Research Institute and Stanford University, scientists have developed and tested a new synthetic surfactant that could lead to improved treatments for lung disease and injury.

Lung surfactant is made up of lipids and proteins which help lower tension on the lung’s surface, reducing the amount of effort needed to take a breath. The proteins, called surfactant-associated proteins, are very difficult to create in a laboratory and so the surfactant most commonly used in medicine is obtained from animal lungs.

London, Ontario has a rich legacy in surfactant research and innovation. Dr. Fred Possmayer, a scientist at Lawson and Western University, pioneered the technique used to purify and sterilize lung surfactant extracted from cows. Called bovine lipid extract surfactant (BLES), the therapeutic is made in London, Ontario and used by nearly all neonatal intensive care units in Canada to treat premature babies with respiratory distress.

A commercially available “quantum computer” has been on the market since 2011, but it’s controversial. The D-Wave machine is nothing like other quantum computers, and until recently, scientists have doubted that it was even truly quantum at all. But the company has released an important new result, one that in part realizes Richard Feynman’s initial dreams for a quantum computer.

Scientists from D-Wave announced they have simulated a large quantum mechanical system with their 2000Q machine—essentially a cube of connected bar magnets. The D-Wave can’t take on the futuristic, mostly non-physics-related goals that many people have for quantum computers, such as finding solutions in medicine, cybersecurity, and artificial intelligence. Nor does it work the same way as the rest of the competition. But it’s now delivering real physics results. It’s simulating a quantum system.

Wounds and burns could one day be treated by the material spiders use to make their webs.

Though the disease was eradicated decades ago, national security experts fear that stocks of the virus in labs could be released as a bioweapon.

Drugs were created to block a protein called the mammalian target of rapamycin (mTOR) and it boosted the immune system by about 40% in elderly people.

They safely reducing infections in elderly volunteers around 40% by enhancing the immune system.

In 2004, tests that blocked a similar enzyme in fruit flies gave them a longer lifespan.

Millions of people take up to five or more medications a day, but doctors have no idea what side effects might arise from adding another drug.*

Now, Stanford University computer scientists have developed a deep-learning system (a kind of AI modeled after the brain) called Decagon** that could help doctors make better decisions about which drugs to prescribe. It could also help researchers find better combinations of drugs to treat complex diseases.

The HPV vaccine has eliminated skin cancer in a 97-year-old woman — giving doctors and patients hope it could be used to treat aggressive cases of skin cancer, such as squamous cell carcinoma.

A 97-year-old woman’s severe case of an untreatable form of squamous cell carcinoma was cleared with injections of the HPV vaccine, her doctors report.
