The new study found that in the subtropical North Atlantic (25°N), 62% of the warming from 1850-2018 is held in the deep ocean.The researchers – from the University of Exeter and the University of Brest – estimate that the deep ocean will warm by a further…

The buildup of bacteria deep in our teeth can cause infections in difficult-to-reach areas, and scientists at the Indian Institute of Science have developed a set of tiny cleaning robots they believe are up to the task. The nano-sized machines can be steered with a magnetic field into microscopic channels in the teeth and kill bacteria with heat, offering a safe and potent way to improve the success of standard root canal treatments.The robots came about through the team's pursuit of new and improved ways to tackle the…

Amber Heard is set to be cross-examined in court as part of her continued testimony in the defamation trial against Johnny Depp this week. Ahead of that, however, new information came to light regarding Heard’s divorce from the Pirates of the Caribbean actor and what actually happened to the money from the settlement that she had vowed to donate. We’d previously heard she donated in the seven-figure range, but that’s a far cry from the millions of dollars she had seemingly pledged around the time of her high-profile…

A top-of-the-line farm tractor stands taller than an African elephant. And fully loaded with grain, a combine harvester weighs up to 36 tons—as much as a small herd of pachyderms. As these mechanical beasts lumber across fields, their extreme heft can slowly crush the soil and make it harder for plant roots to grow. Such effects, a new study suggests, could diminish harvests across 20% of global cropland in the coming decades. “Heavy machinery is something we should not ignore,”…

Every now and then, there is a debate whether Aurangzeb was a villain or a hero. Such debates become even more important when very few people know about his personal life. Aurangzeb had two Hindu wives-one a Rajput named Udaipuri and another Nawab Bai. Udaipuri was so much in love with the sixth Mughal emperor that she had expressed her wish to perform ‘sati’ if Aurangzeb died before her. This fact was mentioned by Aurangzeb himself in a letter to his son Kambaksh. Interestingly, the two died within months in 1707.…
