Sparks of joy

What if a jolt of electricity could make you happy? People all around the world have been exhausting themselves of late trying to “spark joy” in their lives. Any emotion we feel has a physical cause inside our brains: Electrical charges pass from neuron to neuron. It seems that what we call happiness is

Turns out the science saying screen time is bad isn’t science | TechCrunch Is screen time good or bad? Hard to sau for sure. A new study is making waves in the worlds of tech and psychology by questioning the basis of thousands of papers and analyses with conflicting conclusions on the effect of screen time on well-being. There seems to be a lot bad science.

Amoeba finds approximate solutions to NP-hard problem in linear time This is intresting finding that Researchers have demonstrated that an amoeba (a single-celled organism) has unique computing abilities. The researchers found that an amoeba can find reasonable (nearly optimal) solutions to the TSP in an amount of time that grows only linearly as the number of cities increases. Traveling Salesman Problem (TSP) is an

The microscope revolution that’s sweeping through materials science 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 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

NASA’s InSight Probe Has Successfully Touched Down On The Surface Of Mars | IFLScience NASA has confirmed that its InSight spacecraft has safely touched down on Mars, the first successful landing on the Red Planet in more than six years. Check also posting on older Mars probe at

Definition of kilogram set to change – BBC News 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 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.
