What Would It Mean for AI to Become Conscious?

Posted by in categories: Ray Kurzweil, robotics/AI

As artificial intelligence systems take on more tasks and solve more problems, it’s hard to say which is rising faster: our interest in them or our fear of them. Futurist Ray Kurzweil famously predicted that “By 2029, computers will have emotional intelligence and be convincing as people.”

We don’t know how accurate this prediction will turn out to be. Even if it takes more than 10 years, though, is it really possible for machines to become conscious? If the machines Kurzweil describes say they’re conscious, does that mean they actually are?

Perhaps a more relevant question at this juncture is: what is consciousness, and how do we replicate it if we don’t understand it?

Potential therapy discovered for deadly breast cancer that has few treatment options

Posted by in categories: biotech/medical, innovation

Mount Sinai researchers have designed an innovative experimental therapy that may be able to stop the growth of triple-negative breast cancer, the deadliest type of breast cancer, which has few effective treatment options, according to a study published in Nature Chemical Biology in December.

The therapy is known is MS1943. In a cell line and mouse models, it degraded a called EZH2 that drives the growth of triple-negative breast cancer.

Research teams led by Jian Jin, Ph.D., Director of the Mount Sinai Center for Therapeutics Discovery, and Ramon Parsons, MD, Ph.D., Director of The Tisch Cancer Institute at Mount Sinai, developed MS1943 as a first-in-class small-molecule agent that selectively degrades EZH2. They also showed that agents that inhibit the enzymatic activity of EZH2 but do not degrade EZH2 did not work in triple-negative breast cancer.

Study shows inhibition of gene helps overcome resistance to immunotherapy

Posted by in categories: biotech/medical, genetics

Cancer immunology drugs, which harness the body’s immune system to better attack cancer cells, have significantly changed the face of cancer treatment. People with aggressive cancers are now living longer, healthier lives. Unfortunately, cancer immunology therapy only works in a subset of patients.

Now, a new study from scientists at the UCLA Jonsson Comprehensive Cancer Center helps explain why some people with advanced cancer may not respond to one of the leading immunotherapies, PD-1 blockade, and how a new combination approach may help overcome resistance to the immunotherapy drug.

The UCLA study, published today in the inaugural issue of the new scientific journal Nature Cancer, showed that genetic and pharmacological inhibition of the oncogene PAK4 overcomes resistance to anti-PD-1 therapy in preclinical models.

Key mystery about how the brain produces cognition is finally understood

Posted by in category: neuroscience

Human behavior is often explained in terms of unseen entities such as motivation, curiosity, anxiety and confidence. What has been unclear is whether these mental entities are coded by specific neurons in specific areas of the brain.

Professor Adam Kepecs at Cold Spring Harbor Laboratory has answered some of these questions in new research published in Nature. The findings could lead to the development of more effective treatments for , compulsive gambling and other psychiatric disorders.

The team studied the , an area critical for decision-making in humans and animals alike. Damage to this region impairs decision-making. In a famous example, Phineas Gage, a railway worker, survived extreme damage to this area when an iron rod pierced his skull in an explosion. Gage survived but his personality and decision-making skills didn’t.

Liquid flow is influenced by a quantum effect in water

Posted by in categories: biotech/medical, quantum physics

Researchers at EPFL have discovered that the viscosity of solutions of electrically charged polymers dissolved in water is influenced by a quantum effect. This tiny quantum effect influences the way water molecules interact with one another. Yet, it can lead to drastic changes in large-scale observations. This effect could change the way scientists understand the properties and behavior of solutions of biomolecules in water, and lead to a better understanding of biological systems.

Water is the basis of all life on earth. Its structure is simple—two bound to one —yet its behavior is unique among liquids, and scientists still do not fully understand the origins of its distinctive properties.

When charged polymers are dissolved in water the aqueous becomes more viscous than expected. This high viscosity is used by nature in the human body. The lubricating and shock-absorbing properties of the synovial fluid—a solution of water and charged biopolymers—is what allows us to bend, stretch and compress our joints over our entire lives without damage.

The US just promised to adopt universal health care

Posted by in categories: biotech/medical, finance, health, sustainability

Every single member of the UN doubled-down today on a commitment to provide universal health coverage to their citizens. The fact that the US will be among them is perhaps evidence of how disconnected these declarations can be from actual domestic political agendas.

Yet the issue is important, and it shows just how out of line the US approach to health care coverage is compared to the rest of the world. Only about half the world’s population has access to the kind of affordable health care services that don’t require crippling out-of-pocket costs. Most of those people are in mid- and low-income countries. Or they are in the wealthiest country on Earth: the US.

Bringing universal health care to everyone is one of the “sustainable development goals,” the ambitious to-do list for UN member countries to complete by 2030. For the UN, universal health care means, “financial risk protection, access to quality essential health-care services and access to safe, effective, quality and affordable essential medicines and vaccines for all.”

Paralyzed man walks using brain-controlled robotic suit

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

A tetraplegic man has been able to move all four of his paralyzed limbs by using a brain-controlled robotic suit, researchers have said.

The 28-year-old man from Lyon, France, known as Thibault, was paralyzed from the shoulders down after falling 40 feet from a balcony, severing his spinal cord, the AFP news agency reported.

He had some movement in his biceps and left wrist, and was able to operate a wheelchair using a joystick with his left arm.

Ultrasound destroys 80 percent of prostate cancers in one-year study

Posted by in categories: biotech/medical, information science

Treating prostate cancer through traditional means such as surgery or radiotherapy carries certain risks, with some patients experiencing impotence, urinary problems and bowel trouble, among other unwanted side effects. Safer and less invasive treatment options could soon be on the table, however, including a novel MRI-guided ultrasound technique that eliminated significant cancers in 80 percent of subjects in a year-long study.

The new technique is called MRI-guided transurethral ultrasound ablation (TULSA) and has been under development for a number of years. The minimally invasive technology involves a rod that enters the prostate gland via the urethra and emits highly controlled sound waves in order to heat and destroy diseased tissue, while leaving healthy tissue unharmed.
