How scientists discovered a math equation in rat whiskers

Rats have up to 70 whiskers on their faces, varying hugely in size, and shape. Almost every mammal possesses whiskers, but these rodents are what we call “whisker specialists,” meaning they have super-sensitive, moveable hairs that they use to explore and sense their surroundings. Rat whiskers can vary hugely. In our recent research, my colleagues and I analyzed 523 whiskers from 15 rats and found that each whisker had a different length and shape. We wanted to investigate more about the shape of these hairs as a first step in understanding what rats feel through their whiskers. We found that…

‘Freezing’ our bodies is the key to long-distance space travel — but can we do it?

Long-distance space travel, traveling at sub-light speeds, will require a way to make the journey with a crew of aging humans. While it’s possible to avoid some of that through time dilation (a quirk of physics that slows down time for anything that speeds up), humans wouldn’t save a large amount of time until the ship reaches 90% of the speed of light. Assuming we could build ships that can go that fast, we could cut aging in half. At 99.5% light speed, we would age at only ten percent relative to an observer at rest. The problem is physics. More…

I am in a location where not every hospital/clinic is digital and not neccesaily one can have access to others. In this case I have to always maintain and carry the thick file of prescriptions and reports with me for every visit . Is theer a open source tool or web based tool where records can be maintained chronolgically for me and family members.

Machine learning for everyone: How to implement pose estimation in a browser using your webcam

The 20th century turned out to be an era of exponential growth in the field of machine learning. The 3000-year-old ancient game of ‘Go’ that computer scientists predicted will take another decade to crack was made possible by Google Brain teams AlphaGo AI, defeating multiple-time world champion Lee Sudol. And, by the way, this Chinese game has more combinations than predicted atoms in the universe or, in short, this game can’t be won just by running through all the possible moves, what IBM Blue did in 1997, defeating world champion Gary Kasparov. Then, the rise of OpenAI’s bot in DOTA2 and other fun (potentially harmful) stuff like Deepfake. Research communities are…

India finally commits to quantum computing, promises $1.12B investment

The Indian government said today it plans to invest ₹8000 crores ($1.12 billion) in quantum computing research over five years. The country’s finance minister, Nirmala Sitharaman, said the scheme will boost the research for technology under the National Mission of Quantum Technology and Application project. India’s investment comes quite late as plenty of nations have already allotted grants for research in the area. In 2016, the European Commission announced €1-billion ($1.13 billion) funding for quantum computing projects. In 2018, US President Donald Trump signed a bill that promised investment of $1.2 billion in the area. Meanwhile, China has already committed over $2 billion…
