� � � � � � Eating fewer calories can ward off ageing - The Economist    In 1991 eight volunteers sealed themselves into a huge greenhouse in the desert near Tucson, Arizona. They were part of an experiment seeking to discover whether a carefully curated selection of plants and animals could develop into a self-sustaining ecosystem: a “Biosphere 2” independent of “Biosphere 1”, aka the outside world. In terms of proving grand ecological truths the Biosphere 2 experiments were something of a bust. As an illustration of what can happen when somewhat fringe-y science meets extreme wealth they were fascinating. There were fierce fallings-out on both sides of the glass. In 1994 Ed Bass, an oil dynast who had paid for the facility, threw out the management team and handed the reins to Steve Bannon, later a key adviser to Donald Trump. At the same time, though, there was what some took to be a breakthrough in the science of human ageing. Biosphere 2 allowed him to test the theory on humans in no position to sneak off for snacks. With a daily intake of 1,750-2,100 calories (7,320-8,790 kilojoules) the biospherians, trim to begin with, all slimmed down. But after eight months their weight stabilised. Gaunt as they were, their energy levels remained high. Blood tests showed physiological responses which matched those of calorie-restricted rodents with extended lifespans.

Go ad-free with TradeBriefs Premium Iran Says It Launched an Imaging Satellite Into Orbit - TIME    (DUBAI, United Arab Emirates) — Iran claimed on Wednesday that it successfully launched an imaging satellite into space, a move that could further ratchet up tensions with Western nations that fear its space technology could be used to develop nuclear weapons. Iran's Communication Minister Isa Zarepour said the Noor-3 satellite had been put in an orbit 450 kilometers (280 miles) above the Earth's surface, the state-run IRNA news agency reported. It was not clear when exactly the launch took place. There was no immediate acknowledgment from Western officials of the launch or of the satellite being put into orbit. The U.S. military did not immediately respond to a request for comment. Iran has had a series of failed launches in recent years.

While there is vast farmland as far as the eye can see, you will be surprised to learn that much of it is owned by only a few families. Many traditionally have kept their land through generations of heirs, but times are changing. More farmland is now hitting the market as a large percentage of America’s farmland is owned by people aged 75 or older, and experts say millions of acres will change hands, with investors being the main recipients. Due to increasing numbers of extended families now separated in remote locations, families are not gathering at these iconic ranches like they used to. Bill McDavid from Hall and Hall, one of the leading brokers for farmland and ranches, says, "When I first entered the business several decades ago, most major ranches for sale were owned by folks who had inherited the property through a generational chain often stretching back to homestead days... they were mostly land rich - cash poor. Their kids had grown up working on the ranch but went off and built a life somewhere else with little interest in returning to the ranch. Or too many siblings created a challenge in fairly bequeathing the ranch. In either case, the owners reached an age where the workload became too much, and it was time to pass the torch."

In those few days, relations between Canada and India have gone from bad to worse. That is serious enough. But the bigger question is what might happen to America’s till now rapidly deepening ties with the South Asian giant. Many in India believe the Americans have hung Mr Trudeau out to dry. They note what appeared to be a fairly non-committal response to his allegation by the administration of President Joe Biden. Instead of fulsomely sounding the alarm, it merely expressed concern and called for India to co-operate with the Canadian investigation into the killing. That perhaps stiffened the resolve of Narendra Modi’s government to brazen the allegations out. India angrily denies them, even as it hints that, whoever did for Mr Nijjar, he had it coming. In this, many Indians cheer their government on. It had long branded the dead Canadian a terrorist for advocating a separate Sikh homeland in Punjab and associating with violent groups dedicated to that cause. Indians grimly recall—as the West generally does not—the bloody insurgency and fierce repression this inspired, from the late 1970s to the early 1990s. It led to tens of thousands of deaths in Punjab and to the assassination in 1984 of Indira Gandhi, India’s then prime minister, by her Sikh bodyguards. Continued here
