Stronger Than Steel, Able to Stop a Speeding Bullet -- It's Super Wood!
Some varieties of wood, such as oak and maple, are renowned for their strength. But scientists say a simple and inexpensive new process can transform any type of wood into a material stronger than steel, and even some high-tech titanium alloys. Besides taking a star turn in buildings and vehicles, the substance could even be used to make bullet-resistant armor plates.
Wood is abundant and relatively low-cost - it literally grows on trees. And although it has been used for millennia to build everything from furniture to homes and larger structures, untreated wood is rarely as strong as metals used in construction. Researchers have long tried to enhance its strength, especially by compressing and "densifying" it, says Liangbing Hu, a materials scientist at the University of Maryland, College Park. But densified wood tends to weaken and spring back toward its original size and shape, especially in humid conditions.
Now, Hu and his colleagues say they have come up with a better way to densify wood

The Biggest Wastes of Time We Regret When We Get Older We spend a lot of energy looking for shortcuts to save time, and sure, those shortcuts add up. But when I look back, my biggest time regrets aren't spending too much time on Twitter or mismanaging my daily tasks. Those are bad habits, but there are bigger, more systematic time wasters that have really gotten in the way. Fixing these will free up a massive amount of time and energy.

Editor's Note: A wide-ranging discussion with Nandan Nilekani. He explains his three-phase Covid -19 vaccination process, says he doesn't see an advertising global giant like Facebook, Google coming out of India, asserts Indian IT is more than "back-end", and believes technology will become part of global geo-politics.
Our digital leap forward and a snare to beware As Information Age companies zoom ahead while most others languish under a covid cloud, India would need to ensure that earning gaps don't result in stagnant mass-market demand
Editor's Note: Indian IT seems to be accelerating during Covid (driven by trends like increased digitization, remote work, etc). This is a good thing, but these are jobs that the vast majority of India will not qualify for. The danger of India falling into the middle income trap (an economic development situation in which a country that attains a certain income (due to given advantages) gets stuck at that level) is real.
