An AI taught itself to play a video game and now it's beating humans

Since the earliest days of virtual chess and solitaire, video games have been a playing field for developing artificial intelligence (AI). Each victory of machine against human has helped make algorithms smarter and more efficient. But in order to tackle real world problems—such as automating complex tasks including driving and negotiation—these algorithms must navigate more complex environments than board games, and learn teamwork. Teaching AI how to work and interact with other players to succeed had been an insurmountable task—until now.

Combination of three gene mutations results in deadly human heart disease

Congenital heart disease occurs in up to 1% of live births, and the infants who are affected may require multiple surgeries, life-long medication, or heart transplants. In many patients, the exact cause of congenital heart disease is unknown. While it is becoming increasingly clear that these heart defects can be caused by genetic mutations, it is not well understood which genes are involved and how they interact. Genetic mutations, also called genetic variants, can also cause poor heart function, but the type and severity of dysfunction varies widely even among those with the same mutation.

'Neural Lander' uses AI to land drones smoothly

Landing multi-rotor drones smoothly is difficult. Complex turbulence is created by the airflow from each rotor bouncing off the ground as the ground grows ever closer during a descent. This turbulence is not well understood nor is it easy to compensate for, particularly for autonomous drones. That is why takeoff and landing are often the two trickiest parts of a drone flight. Drones typically wobble and inch slowly toward a landing until power is finally cut, and they drop the remaining distance to the ground.

Groundwater swelled up and down in wells as far away as Hawaii. Twenty-eight people died. It went down in Yellowstone history as the Hebgen Lake earthquake, with a magnitude of 7.2.

Until now, researchers—and companies that sell the compound for human use in the form of a nutraceutical—have attributed the effects to SR9009's role in altering the body's circadian clock, specifically its work through proteins called REV-ERBS that link metabolism and circadian rhythm. However, in a first-of-its-kind study from Penn Medicine, published today in PNAS, researchers found that SR9009 can effect cell growth and metabolic function without the involvement of REV-ERBs.

Computer scientists at The University of Texas at Austin have taught an artificial intelligence agent how to do something that usually only humans can do—take a few quick glimpses around and infer its whole environment, a skill necessary for the development of effective search-and-rescue robots that one day can improve the effectiveness of dangerous missions. The team, led by professor Kristen Grauman, Ph.D. candidate Santhosh Ramakrishnan and former Ph.D. candidate Dinesh Jayaraman (now at the University of California, Berkeley) published their results today in the journal Science Robotics.

Just like toothpaste: Fluoride radically improves the stability of perovskite solar cells

Solar cells made of perovskite hold much promise for the future of solar energy. The material is cheap, easy to produce and almost as efficient as silicon, the material traditionally used in solar cells. However, perovskite degrades quickly, severely limiting its efficiency and stability over time. Researchers from Eindhoven University of Technology, energy research institute DIFFER, Peking University and University of Twente have discovered that adding a small amount of fluoride to the perovskite leaves a protective layer, increasing stability of the materials and the solar cells significantly. The solar cells retain 90 percent of their efficiency after 1000 hours operation at various extreme testing conditions. The findings are published today in the leading scientific journal Nature Energy.

Imagine: Our attitudes can change solely by the power of imagination

Sometimes in life there are special places that seem to stand out to us—a school playground, perhaps an old church, or that inconspicuous street corner where you were kissed for the first time. Before the kiss you had never even noticed that corner. It's as if the special experience with that beloved person transferred positive emotion to the location. Our attitude towards these places thus suddenly changes—they become valuable to us. But could this also happen purely by the power of imagination rather than by actual experiences?

A simplified method to categorize olive oil

Olive oil classification is currently very costly and slow. In order to categorize oil into extra virgin (EVOO), virgin (VOO) and lampante olive oil (LOO), an offical method is used, consisting of a physicochemical analysis and a sensory analysis in the end. This last part is based on the work of a panel of expert tasters who try each olive oil one by one in order to determine its category. This process is very costly for the bottlers. For this reason, they are keen on developing a complementary analytical classification method. Moreover, there are very few expert olive oil tasters in other countries, hence the urgency to find another way to categorize olive oil that does not involve sensory analysis.

Clean and effective electronic waste recycling

As the number of electronics devices increases around the world, finding effective methods of recycling electronic waste (e-waste) is a growing concern. About 50 million tons of e-waste is generated each year and only 20% of that is recycled. Most of the remaining 80% ends up in a landfill where it can become an environmental problem. Currently, e-waste recycling involves mechanical crushers and chemical baths, which are expensive, and manual labor, which can cause significant health and environmental problems when not performed properly. Thus, researchers from Kumamoto University, Japan have been using pulsed power (pulsed electric discharges) to develop a cleaner and more efficient recycling method.

A versatile experimental method to achieve simultaneous control of the number and the transfer energy of the electrons has been long desired.
