Astronomers say they have spotted evidence of stars fuelled by the annihilation of dark matter particles. If true, it could solve the cosmic mystery of how supermassive black holes appeared so early.

“Science, Technology, and Exaltation,” Keynote Speech by Ralph Merkle
At the 2015 Conference of the Mormon Transhumanist Association, held 3 Apr 2015 at the Salt Lake City Public Library, speakers addressed the themes of Mormonism, Transhumanism and Transfigurism, with particular attention to topics at the intersection of technology, spirituality, science and religion. Members, friends and critics of the association have many views. This is one of them. It is not necessarily shared by others.
Suppressing negative thoughts may be good for mental health after all, study suggests
“We’re all familiar with the Freudian idea that if we suppress our feelings or thoughts, then these thoughts remain in our unconscious, influencing our behaviour and wellbeing perniciously,” said Anderson. “The whole point of psychotherapy is to dredge up these thoughts so one can deal with them and rob them of their power.” It had become dogma in clinical psychology that efforts to banish thoughts or memories of a particular subject were counterproductive and made people think more about them, he said. “We challenge the view that thought suppression worsens mental illness.” https://www.ft.com/content/5495b3ee-6c08-4d89-a614-c0acb83aa9a6
The commonly-held belief that attempting to suppress negative thoughts is bad for our mental health could be wrong, a new study from scientists at the University of Cambridge suggests.

New tool measures plasma source and color of light simultaneously to improve microchip production
Researchers at MESA+ Institute for Nanotechnology developed a tool that can measure the size of a plasma source and the color of the light it emits simultaneously. “Measuring both at the same time enables us to further improve lithography machines for smaller, faster and improved chips.” The article is highlighted as an Editor’s pick in Optics Letters.
Lithography machines are central to the process of making the microchips that are needed for almost all our electronic devices. To produce the smallest chips, these machines need precision-engineered lenses, mirrors and light sources. “Traditionally, we could only look at the amount of light produced, but to further improve the chipmaking process, we also want to study the colors of that light and the size of its source,” explains Muharrem Bayraktar, assistant professor at the XUV Optics Group.
The extreme ultraviolet light is emitted by a plasma source, produced by aiming lasers at metal droplets. With sets of special mirrors, this light is aimed at a silicon wafer to create the smallest microchips imaginable. “We want to make the plasma as small as possible. Too large and you ‘waste’ a lot of light because the mirrors cannot catch all the light,” says Bayraktar.
How long do residential solar batteries last?
In the first and second parts of this series, pv magazine reviewed the productive lifespan of residential solar panels and inverters. Here, we examine home batteries, how well they perform over time, and how long they last.
Residential energy storage has become an increasingly popular feature of home solar. A recent SunPower survey of more than 1,500 households found that about 40% of Americans worry about power outages on a regular basis. Of the survey respondents actively considering solar for their homes, 70% said they planned to include a battery energy storage system.
Besides providing backup power during outages, many batteries are integrated with technology that allows for intelligent scheduling of the import and export of energy. The goal is to maximize the value of the home’s solar system. And, some batteries are optimized to integrate an electric vehicle charger.
Toyota upends robot learning: New AI masters complex tasks in hours
“We’ve had a bit of a breakthrough.” Toyota, MIT and Columbia Engineering have shown off wild results from a new AI learning approach that massively accelerates how quickly robots can acquire new skills. It looks like a ChatGPT moment for robotics.
