By grinding up nanotubes and dipping them in special solvents, the team showed it’s possible to generate enough current to run important electrochemical reactions, and maybe one day to power super-small devices.
As more kids go down the ‘deep, dark tunnel’ of long Covid, doctors still can’t predict who is at risk.
“She was a completely healthy, active kid and this just totally changed her life,” her mother, Sara Dardis, said. “So obviously, Covid is real and it’s real for kids. It needs to be taken seriously.”
Kate’s story makes clear that long Covid is not an adults-only phenomenon. Numbers are hard to come by, but more children and adolescents are experiencing chronic symptoms after Covid even as the pandemic ebbs in the U.S., say doctors at the few clinics devoted to caring for them. Although the disease has played out in ways that differ between adults and children, long Covid is posing the same mystery in kids as in adults.

Researchers at Purdue University, Indiana, have developed a method to transform ordinary clothes into battery-free wearables that are waterproof and resistant to laundry. These smart fabrics can be powered wirelessly through a flexible, silk-based coil sewn on the textile.
The Hong Kong team behind celebrity humanoid robot Sophia is launching a new prototype, Grace, targeted at the healthcare market and designed to interact with the elderly and those isolated by the COVID-19 pandemic.

They’ve only gone and upended a widely held scientific idea.
Lilia Koelemay, a graduate researcher at the University of Arizona, said in a statement about the study that “the detection of these organic molecules at the galactic edge may imply that organic chemistry is still prevalent at the outer reaches of the galaxy, and the [galatic habitable zone] may extend much further from the galactic center than the currently established boundary.”
Koelemay also said, “The widely held assumption was that in the outskirts of our galaxy, the chemistry necessary to form organics just doesn’t occur.”
I believe that telepathy is a universal language that breaks all borders between all creatures and we should do more researches on it.
An international research team develops a way to say “hello” with your mind.

Our genetic material is stored in our cells in a specific way to make the meter-long DNA molecule fit into the tiny cell nucleus of each body cell. An international team of researchers at the Max Planck Institute for Biology of Aging, the CECAD Cluster of Excellence in Aging Research at the University of Cologne, the University College London and the University of Michigan have now been able to show that rapamycin, a well-known anti-aging candidate, targets gut cells specifically to alter the way of DNA storage inside these cells, and thereby promotes gut health and longevity. This effect has been observed in flies and mice. The researchers believe this finding will open up new possibilities for targeted therapeutic interventions against aging.
Our genetic material lies in the form of DNA in every cell nucleus of our body cells. In humans, this DNA molecule is two meters long—yet it fits into the cell nucleus, which is only a few micrometers in size. This is possible because the DNA is precisely stored. To do this, it is wound several times around certain proteins known as histones. How tightly the DNA is wound around the histones also determines which genes can be read from our genome. In many species, the amount of histones changes with age. Until now, however, it has been unclear whether changes in cellular histone levels could be utilized to improve the aging process in living organisms.

Going to eco-extremes to try and save the planet is a great thing to do, but for the majority of us, it’s not an easy thing to do. If everybody makes a few easy little changes to live more sustainably, it’ll have a far bigger impact. And with our range of affordable, everyday solutions, the power of change is in everybody’s hands. The difference isn’t going to be made with a few grand gestures, it’ll be when we all change a bit for good.
