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.

More democracy: A second chance for climate politics

Hope was high when the Paris Climate Agreement was adopted 2015. Under the agreement, countries pledged to keep global warming well below two degrees Celsius. Five years later, the situation is sobering: Global emissions of carbon dioxide and other climate-relevant gases continue to rise. In an article in Science, Mark Lawrence and Stefan Schäfer of the Institute for Advanced Sustainability Studies (IASS) argue that the centralized approach to addressing global warming has failed and only greater democratic engagement can reanimate global climate politics.

Nanoscale sculpturing leads to unusual packing of nanocubes

From the ancient pyramids to modern buildings, various three-dimensional (3-D) structures have been formed by packing shaped objects together. At the macroscale, the shape of objects is fixed and thus dictates how they can be arranged. For example, bricks attached by mortar retain their elongated rectangular shape. But at the nanoscale, the shape of objects can be modified to some extent when they are coated with organic molecules, such as polymers, surfactants (surface-active agents), and DNA. These molecules essentially create a "soft" shell around otherwise "hard," or rigid, nano-objects. When the nano-objects pack together, their original shape may not be entirely preserved because the shell is flexible—a kind of nanoscale sculpturing.

Early dengue virus infection could 'defuse' Zika virus

"We now know for sure that Zika virus infection during pregnancy can affect the unborn foetus in such a way that the child develops microcephaly and other severe symptoms," explains Prof Felix Drexler, a virologist at Charité who has been developing diagnostic tests for Zika and other viruses at the DZIF. Just a few years ago, pictures of affected newborns were cause for worldwide dismay and perplexity. "However, what we did not understand then was that high incidence of microcephaly seemed to occur particularly in northeastern Brazil," says Drexler. Why are expecting mothers in these regions at a higher risk of developing a severe Zika-associated disease than in other regions? The scientists consequently began to search for cofactors that have an influence on whether a Zika infection during pregnancy will develop fatal consequences or not.

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.

Long associated with decreased risk of cancer, broccoli and other cruciferous vegetables—the family of plants that also includes cauliflower, cabbage, collard greens, Brussels sprouts and kale—contain a molecule that inactivates a gene known to play a role in a variety of common human cancers.

Other symptoms, such as loss of strength and sensation in the arms and legs, muscle stiffness, and impaired speech, hearing, and vision, can also result. New research in cell models and in mice suggests that limited environmental oxygen, known as hypoxia, might one day help FRDA patients, although the safety of doing so is yet unknown.

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

A surprising experiment opens the path to new particle manipulation methods

Researchers at Aalto University have discovered a surprising phenomenon that changes how we think about how sound can move particles. Their experiment is based on a famous experiment recognisable from high school science classrooms worldwide—the Chlandni Plate experiment, where particles move on a vibrating surface. The experiment was first performed in 1787 by Ernst Chladni, who is now known as the father of acoustics. Chladni's experiment showed that when a plate is vibrating at a certain frequency, heavy particles move towards the regions with less vibration, called nodal lines. This experiment has been extensively repeated during the centuries since, and has shaped the common understanding of how heavy particles move on a vibrating plate. But researchers at Aalto University have now shown a case where heavy particles move towards the regions with more vibrations, or antinodes. "This is a surprising result, almost a contradiction to common beliefs," says Professor Quan Zhou.
