FRIDAY, March 25, 2016 — Brain stimulation may ease major symptoms of the eating disorder anorexia nervosa, a typically hard-to-treat condition, a new study suggests.

British researchers evaluated anorexia patients before and after they underwent repetitive transcranial stimulation (rTMS), a treatment approved for depression.

“With rTMS we targeted … an area of the brain thought to be involved in some of the self-regulation difficulties associated with anorexia,” study first author Jessica McClelland, a postdoctoral researcher at King’s College London, said in a school news release.

Researchers from Griffith University and the University of Queensland have overcome one of the key challenges to quantum computing by simplifying a complex quantum logic operation. They demonstrated this by experimentally realising a challenging circuit — the quantum Fredkin gate — for the first time.

“The allure of quantum computers is the unparalleled processing power that they provide compared to current technology,” said Dr Raj Patel from Griffith’s Centre for Quantum Dynamics.

“Much like our everyday computer, the brains of a quantum computer consist of chains of logic gates, although quantum logic gates harness quantum phenomena.”

Nuclear fusion needs a “Wright brothers” moment, to convince the world of its promise of unlimited clean and safe energy and so unlock significant private investment, according to a physicist whose says his company is closing in on that goal.

David Kingham, the chief executive of Tokamak Energy, has announced his company’s target of producing its first electricity by 2025 and feeding power into the grid by 2030, as well as investment from the UK’s Institution of Mechanical Engineers.

Harnessing the nuclear energy which powers the sun has long been touted as the ultimate solution to the challenge of powering the world while halting climate change. But, as fusion sceptics often say, the reality has stubbornly remained a decade or two away for many years.
