Swapping animal products for future foods such as insect protein or cultured milk could reduce global warming, water and land use by over 80 per cent, a new study suggests. Researchers used computer modelling to find the optimal diet combination to meet nutritional needs, while also minimising global warming potential, water and land use. They found that if people in Europe replaced meat and dairy with foods produced through new technologies, such as making fake steak out of bovine cells, it could significantly reduce all environmental impacts. Not only that, but it would be nutritionally adequate and meet the constraints...

A third dose of coronavirus vaccine may be needed to prevent serious cases of new variants of the disease, Bill Gates said Tuesday. The billionaire philanthropist's comments come amid to the growing concern that current vaccines are less effective against the South African and Brazilian variants.

We pooped out before all the snow was gone, and when we asked to be paid, the old man refused. "You don't finish, I don't pay," he said. We skulked off. But those were the rules of the marketplace. You wanna get paid, you gotta do the job. Simple enough, right? Apparently not in corporate America, where CEOs regularly leave their companies in no better shape than when they got there, yet walk...

Jeddah: George Soros is warning all oil-producing countries about pegging their currencies and oil revenues to the dollar. "The US dollar is weak, and is expected to deteriorate more," said Soros.

Many central banks intend to peg their currencies to the euro and increase their balances of European currency against the...
