How would you like your burger printed? The launch of Israeli foodtech firm SavorEat’s plant-based burger system makes it one of the first restaurants to use 3D printing technology, according to Reuters. Their on-site printer has three cartridges filled with oils and other ingredients (including potato, chickpea, and pea protein), allowing customers to choose the amount of fat and protein in their burger for a personalized meal. SavorEats’ 3D-printing “robot chefs” will initially only be rolled out in some branches of a local burger chain, but the company is inking an agreement to serve the burgers at US universities. It’s now working on similar technology to create a vegan alternative for breakfast sausages to further penetrate the US market.

Elon Musk is getting slapped with one of the largest tax bills in US history after going on a selling spree of his Tesla shares last year, according to CNN. In November, Musk set up a Twitter poll asking his followers whether or not he should sell USD 21 bn (10%) of his shares in the automaker, claiming that it was “the only way” for him to pay taxes personally. During the second week of November, he sold USD 6.9 bn worth of his Tesla shares, and has continued to sell shares in the company through last week, bringing his federal tax bill to USD 10.7 bn, at a tax rate of 40.8%.

Blanket booster programs are likely to prolong the pandemic, rather than end it, warns WHO: World Health Organization (WHO) chief Tedros Ghebreyesus has criticized blanket vaccine booster programs that divert supply to wealthier countries as poor countries struggle to obtain initial doses. Unequal access to immunizations could lead to more mutated variants that drag out the global health emergency, Ghebreyesus told reporters in Geneva last month. The WHO has repeatedly discouraged booster programs amid rampant vaccine inequality, but has been widely ignored by developed countries, many of which have rolled out nationwide booster programs as they struggle to get a grip on the omicron variant.
