An artificial intelligence (AI) known as AlphaStar — which was built by Google’s AI firm DeepMind — achieved a grandmaster rating after it was unleashed on the game’s European servers, placing within the top 0.15% of the region’s 90,000 players.
StarCraft II’s complexity poses immense challenges to AIs. Unlike chess, StarCraft II has hundreds of ‘pieces’ — soldiers in the factions’ armies — that move simultaneously in real time, not in an orderly, turn-based fashion. Whereas a chess piece has a limited number of legal moves, AlphaStar has 1026 actions to choose from at any moment. And StarCraft II, unlike chess, is a game of imperfect information — players often cannot see what their opponent is doing. This makes it unpredictable.

The university is launching a Center for Psychedelic and Consciousness Research within John Hopkins Medicine. It’s believed to be the first of its kind in the U.S. and the largest research center of its kind in the world, according to the school.
“Johns Hopkins is deeply committed to exploring innovative treatments for our patients,” said Paul B. Rothman, dean of the medical faculty at the Johns Hopkins University School of Medicine, in a statement. “Our scientists have shown that psychedelics have real potential as medicine, and this new center will help us explore that potential.”

Finally a positive evolution in the mentality of scientists, towards more openness?
How do statistics so often lead scientists to deny differences that those not educated in statistics can plainly see? For several generations, researchers have been warned that a statistically non-significant result does not ‘prove’ the null hypothesis (the hypothesis that there is no difference between groups or no effect of a treatment on some measured outcome). Nor do statistically significant results ‘prove’ some other hypothesis. Such misconceptions have famously warped the literature with overstated claims and, less famously, led to claims of conflicts between studies where none exists.

The human body naturally forms a protein called alpha-synuclein which is found, among other places, in the brain in the endings of nerve cells. However, misfolded forms of this protein that clump together are linked to damage to nerve cells, a deterioration of the dopamine system and the development of problems with movement and speech – hallmarks of Parkinson’s disease.
The latest findings, which are based on studies in mice, back up a long-held theory that abnormally folded alpha-synuclein may start off in the gut and then spread to the brain via the vagus nerve – a bundle of fibres that starts in the brainstem and transports signals to and from many of the body’s organs, including the gut.

“Cats are just as good as dogs at learning — they’re just not as keen to show their owners what they’ve learnt,” says John Bradshaw, a biologist at the University of Bristol, UK, who specializes in human–animal interactions.
The study took advantage of a technique known as ‘habituation–dishabituation’, commonly used in animal-behaviour studies. Atsuko Saito, a cognitive biologist at the University of Tokyo, and her colleagues visited 11 households with pet cats (Felis catus) and asked the owner to read a list of four nouns to their pet. These words were of the same length and rhythm as the cat’s name.

If you bled when you brushed your teeth this morning, you might want to get that seen to. We may finally have found the long-elusive cause of Alzheimer’s disease: Porphyromonas gingivalis, the key bacteria in chronic gum disease.
That’s bad, as gum disease affects around a third of all people. But the good news is that a drug that blocks the main toxins of P. gingivalis is entering major clinical trials this year, and research published today shows it might stop and even reverse Alzheimer’s. There could even be a vaccine.

Universities determine the future: they shape it through their research and prepare students for tomorrow’s jobs. But in the midst of the fourth industrial revolution, it’s hard to know what the future will look like. Technological changes such as automation and artificial intelligence are expected to transform the employment landscape. The question is: will our education system keep up?
The answer matters because an estimated 65% of children entering primary schools today will work in jobs and functions that don’t currently exist, according to a recent Universities UK report. The research, which explores the “rapid pace of change and increasing complexity of work”, also warns that the UK isn’t even creating the workers that will be needed for the jobs that can be anticipated. By 2030, it will have a talent deficit of between 600,000 and 1.2 million workers in the financial and business sector, and technology, media and telecommunications sector.
University leaders would be “foolish” not to pay attention, says Lancaster University vice-chancellor Mark E Smith. “We look at the trends in the job market and the skills employers are looking for, and we listen to what employers are saying. We don’t want to be talking about yesterday’s problem.”

Police in the UK want to predict serious violent crime using artificial intelligence, New Scientist can reveal. The idea is that individuals flagged by the system will be offered interventions, such as counselling, to avert potential criminal behaviour.
However, one of the world’s leading data science institutes has expressed serious concerns about the project after seeing a redacted version of the proposals.
The system, called the National Data Analytics Solution (NDAS), uses a combination of AI and statistics to try to assess the risk of someone committing or becoming a victim of gun or knife crime, as well as the likelihood of someone falling victim to modern slavery.
West Midlands Police is leading the project and has until the end of March 2019 to produce a prototype.
