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.

So for us the World is truly One.
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.”
What’s next — The new finding overturns this assumption, and researchers can now widen the search for life to stars closer to the galaxy’s outer edge, a no-man’s-land of cold matter, isolated stars, and black holes left from long-ago stellar explosions. It’s a place Koelemay says has fewer stars like our life-giving Sun.
I believe that telepathy is a universal language that breaks all borders between all creatures and we should do more researches on it.

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.

A Penn State scientist studying crystal structures has developed a new mathematical formula that may solve a decades-old problem in understanding spacetime, the fabric of the universe proposed in Einstein’s theories of relativity.
“Relativity tells us space and time can mix to form a single entity called spacetime, which is four-dimensional: three space-axes and one time-axis,” said Venkatraman Gopalan, professor of materials science and engineering and physics at Penn State. “However, something about the time-axis sticks out like sore thumb.”
For calculations to work within relativity, scientists must insert a negative sign on time values that they do not have to place on space values. Physicists have learned to work with the negative values, but it means that spacetime cannot be dealt with using traditional Euclidean geometry and instead must be viewed with the more complex hyperbolic geometry.
