To keep up with an impending astronomical increase in data about our universe, astrophysicists turn to machine learning.

Our universe is permeated with a vast, unseen force that seems to oppose gravity. Physicists call this force dark energy, and it is thought to be constantly pushing our universe outward.

But in June, a group of physicists published a paper in the preprint journal arXiv implying that dark energy changes over time. This means that the universe will not expand forever but might eventually collapse into the size it was before the Big Bang.

Almost immediately, however, physicists found problems with the theory: Several independent groups subsequently published papers that suggested revisions to the conjecture. Now, a paper published on Oct. 2 in the journal Physical Review D suggests that, as it stands, the original conjecture can’t be true because it can’t explain the existence of the Higgs boson — which we know exists, thanks to the Large Hadron Collider, the massive particle collider on the border between France and Switzerland.

Scientists from Russia, China and the United States predicted and have now experimentally identified new uranium hydrides, predicting superconductivity for some of them. The results of their study were published in Science Advances.

Fletcher told the ABC the guidelines were developed in consultation with people living with autism, researchers and doctors, and had been approved by the National Health and Medical Research Council.

“It does not change what the NDIS does and indeed it may well be that there are people who, today, would not be diagnosed who will be diagnosed,” he said. “That will be a judgment for clinicians and medical profession and the NDIS will continue to do what it does, which is make an assessment of the impairment that somebody suffers as a result of a disability. Is it likely to be permanent and lifelong? Is it significant? What impact does it have on the functioning?”

Dr Wenn Lawson, the co-chair of the Australian Autism Research Council, said a consistent assessment and diagnosis process for autism meant people would be able to access more appropriate supports.

The impact of gravitational-microlensing observations from 1993.

On October 16, 2017, an international group of astronomers and physicists excitedly reported the first simultaneous detection of light and gravitational waves from the same source—a merger of two neutron stars. Now, a team that includes several University of Maryland astronomers has identified a direct relative of that historic event.

“This may be the best example of an animal masquerading as a plant that we have,” biologist Nicholas Paul, an expert on seaweed and algae at Australia’s University of the Sunshine Coast, said in an email. He wasn’t involved with the new study.

The new species exclusively feed on the seaweed genus Caulerpa and are found throughout the Pacific, including Malaysia, Australia, Guam, and the Philippines. Humans consider the algae’s caviar-like bulbs, called sea grapes, a delicacy—but few sea creatures dare eat the stuff, making them highly invasive. Thanks to the global aquarium trade, the algae has invaded waters from the Mediterranean to Japan.
