The microscope revolution that’s sweeping through materials science

https://www.nature.com/articles/d41586-018-07448-0 Technological advances are transforming what researchers can study at the atomic scale. Using an ultra-sensitive detector that the researchers had created and a special method for reconstructing the data, they resolved features in MoS2 down to 0.39 angstroms, two and a half times better than a conventional electron microscope would achieve. The advanced transmission

To Crack the Toughest Optimization Problems, Just Add Lasers – IEEE Spectrum

https://spectrum.ieee.org/computing/hardware/to-crack-the-toughest-optimization-problems-just-add-lasers Optimization is very important but is usually computationally very hard. Optimization encompasses far more than the traveling salesman problem. Scheduling is another difficult optimization challenge. Given the fact that the era of steady, large improvements in computer-processor performance appears to be coming to a close, researchers have begun to explore machines specially designed for

Definition of kilogram set to change – BBC News

https://www.bbc.com/news/science-environment-46143399 Soon kilogram might not be exactly what it used to be. Scientists plan to change the way the kilogram is defined. Currently, it is defined by the weight of an aging platinum-based ingot called “Le Grand K” located in Paris. Many scientists favour of defining a kilogram in terms of an electric current, but

Ageing in Human Cells Successfully Reversed in the Lab

https://www.technologynetworks.com/neuroscience/articles/ageing-in-human-cells-successfully-reversed-in-the-lab-307820 The ability to reverse ageing is something many people would hope to see in their lifetime. We still don’t fully understand why cells become senescent as we age. Reversing aging is still a long way from reality, but this latest laboratory experiment seems to show that scientists have reversed the ageing of human cells.

Landmark UN Climate Change Report: Act Now To Avoid Climate Catastrophe | IFLScience

https://www.iflscience.com/environment/landmark-un-climate-change-report-act-now-to-avoid-climate-catastrophe/ The Intergovernmental Panel on Climate Change (IPCC) has unleashed their Special Report on the impact of global warming reaching 1.5°C above pre-industrial levels. “This IPCC report is set to outline a rescue plan for humanity,” “1.5°C is the new 2°C,” If we stick to Paris Climate Agreement commitments, we could still see a global

Scientists Have Connected The Brains of 3 People, Enabling Them to Share Thoughts

https://www.sciencealert.com/brain-to-brain-mind-connection-lets-three-people-share-thoughts This is fancy as one science fiction coming reality! Neuroscientists have successfully hooked up a three-way brain connection to allow three people share their thoughts – and in this case, play a Tetris-style game. The team thinks this wild experiment could be scaled up to connect whole networks of people. It works through a

Ig Nobel win for kidney stone removing roller-coaster – BBC News

https://www.bbc.co.uk/news/science-environment-45513012 Some science news for this Friday: Riding on some types of roller-coaster is an effective way of removing kidney stones is the conclusion of research that has won this year’s Ig Nobel Prize for Medicine. The Ig Nobels are spoof prizes that recognise achievements that make people laugh but also then think for a
