Uber discontinues its loyalty program, renewable energy could pay for itself within six years, and scientists create a promising bioengineered cornea.

Uber will be discontinuing its Uber Rewards loyalty program this November. The program, first launched in 2018, gave points to Uber riders and Uber Eats users, which can then be used to unlock perks, like price protection against price surges, and priority pickup at airports. According to Verge, there won’t be a replacement for Uber Rewards, but Uber suggests signing up for the Uber One membership, which costs $10 a month and provides its own perks, like reduced delivery fees on Uber Eats orders.
New research from Stanford University has found that it takes just six years for renewable energy to recuperate the transition cost. Additionally, the study estimates that the transition would create 28 million more jobs than it would cause loss. Out of the 145 countries studied, the only three regions expected to see a net job loss were Russia, Canada, and parts of Africa, all of which are major oil producers. The study concluded that once the transition completes, it would be cheaper than continuing with current energy systems.

A bioengineered cornea has successfully restored vision to people with impaired eyesight. According to a paper published in Nature Biotechnology, these corneas could replace human corneas when they’re in short supply. And unlike corneas extracted from humans that need to be transplanted within two weeks, the man-made ones can be stored for two years. These corneas, which are made from collagen protein extracted from pig skin, are also cheaper than human ones. According to the MIT Technology Review, around 12.7 million people suffer from Corneal blindness globally.

The Lawrence Livermore National Laboratory has confirmed that it has achieved ignition during a fusion nuclear reaction. The milestone was actually made last year, but now it’s been officially published. Nuclear fusion is an attractive method of creating energy as it creates less radioactive materials. Additionally, it can use more abundant materials, like hydrogen, as fuel, instead of uranium used in today’s fission reactors. Achieving ignition during a fusion reaction means that the reaction is producing enough energy to sustain itself. This has been extremely difficult to accomplish due to the difficulties in creating an optimal environment for the reaction.
