The universe is expanding at an ever-accelerating rate. At least, that’s what the vast majority of scientists would have you believe. But according to a team of Spanish physicists, it may not be the expansion of the universe that’s changing rate, but time itself. Time might be slowing down, and that means that it could eventually stop altogether.
I can imagine the meeting: A dozen engineers are gathered around a conference table to discuss automobile safety. How can we protect people during a car crash? We have already added seat belts and crumple zones to cars. Is there anything else we can include? One attendee reluctantly raises their hand with a suggestion: “How about we add an explosive in the steering wheel?”
New Delhi, Oct 6: There are many unsung and forgotten heroes that India has in abundance. One such man whose 125th birth anniversary falls today is Meghnad Saha who was not only nominated for the Nobel Prize in Physics more than once but was also elected to the first Lok Sabha in 1952 as an independent candidate defeating the Congress nominee Prabhu Dayal Himatsingka. But more interestingly he was the chairperson of Calender Reforms Committee set up in 1952.
No one can forget the role of Planning Commission of India in the growth trajectory of the country which was actually conceived by Subhash Chandra Bose at the Haripura Congress in 1938. Bose as a president proposed it as National Planning Committee in which Saha had shown very keen interest.

IBM researchers are developing a new computer architecture, better equipped to handle increased data loads from artificial intelligence. Their designs draw on concepts from the human brain and significantly outperform conventional computers in comparative studies. They report on their recent findings in the Journal of Applied Physics.
Today’s computers are built on the von Neumann architecture, developed in the 1940s. Von Neumann computing systems feature a central processer that executes logic and arithmetic, a memory unit, storage, and input and output devices. Unlike the stovepipe components in conventional computers, the authors propose that brain-inspired computers could have coexisting processing and memory units.
Abu Sebastian, an author on the paper, explained that executing certain computational tasks in the computer’s memory would increase the system’s efficiency and save energy.
It might already feel like social media is taking up too much of our mental space, but just wait until it’s literally inside of our brains.
Physicists and neuroscientists have developed the world’s first “brain-to-brain” network, using electroencephalograms (EEGs), which record electrical activity in the brain, and transcranial magnetic stimulation (TMS), which can transmit information into the brain, to allow people to communicate directly with each other’s brains — a new and thrilling (and a little terrifying?) example of science fiction brought to life.
Researchers at the University of Washington in Seattle announced last week that they successfully used their interface, which they call BrainNet, to have a small group of people play a collaborative “Tetris-like” game — with their minds.
