Why are the biggest and most influential tech companies making deals with oil companies that exacerbate one of the biggest threats to human civilisation?

Though it may not have the sting of death and taxes, presbyopia is another of life’s guarantees. This vision defect plagues most of us starting about age 45, as the lenses in our eyes lose the elasticity needed to focus on nearby objects. For some people reading glasses suffice to overcome the difficulty, but for many people the only fix, short of surgery, is to wear progressive lenses.

“More than a billion people have presbyopia and we’ve created a pair of autofocal lenses that might one day correct their vision far more effectively than traditional glasses,” said Stanford electrical engineer Gordon Wetzstein. For now, the prototype looks like virtual reality goggles but the team hopes to streamline later versions.

Wetzstein’s prototype glasses—dubbed autofocals—are intended to solve the main problem with today’s progressive lenses: These traditional glasses require the wearer to align their head to focus properly. Imagine driving a car and looking in a side mirror to change lanes. With progressive lenses, there’s little or no peripheral focus. The driver must switch from looking at the road ahead through the top of the glasses, then turn almost 90 degrees to see the nearby mirror through the lower part of the lens.

Researchers at Germany’s Max Planck Institute for Intelligent Systems have developed a new type of self-assembling mobile micromachine that can be programmed to assemble into different formations — ranging from a tiny car to a miniature rocket. Here’s what’s next for the project.

Researchers may be closer to improving the lives of people with coronary artery disease and children born with pediatric congenital cardiovascular defects through the development of a new vascular graft created by Johns Hopkins engineers that takes less than one week to make and has regenerative properties.

Coronary artery disease, or CAD, is the leading cause of death worldwide and people with the disease often require surgery to repair damaged cardiovascular tissue. Bypass surgery, another common intervention, requires removing the damaged tissue and replacing it with blood vessels from another part of the body, such as the saphenous vein, which runs the length of the leg and is the longest vein in the body. This method puts substantial stress on the body and has other risk factors: it requires patients to have multiple surgical sites, and those in need of the surgery because of plaque build-up may also have plaque accumulation in the grafted vein, causing further complications.

Congenital cardiovascular defects, or CCD, occurs in 1% of live births worldwide, and children born with the condition often undergo repeated surgical reconstruction as they grow. But repeated surgeries reduce the amount of usable vascular tissue for reconstruction and synthetic grafts do not grow as the child grows.

Lurking behind Einstein’s theory of gravity and our modern understanding of particle physics is the deceptively simple idea of symmetry. But physicists are beginning to question whether focusing on symmetry is still as productive as it once was.

Just a few months ago, Augustín Carstens, the general manager for the Bank for International Settlements (BIS), the so-called central bank for central banks, said his organization saw no value in the potential of central-bank-issued digital currencies. Well, he’s apparently had a change of heart, and the entrance of Facebook and other “big techs” into financial services appears to be the reason.

The news: Carstens told the Financial Times that the BIS is supporting the “many” central banks currently developing or researching digital currencies. “And it might be that it is sooner than we think that there is a market and we need to be able to provide central bank digital currencies,” he said.

The context: Many other central bankers have dismissed cryptocurrencies like Bitcoin, which tend to be volatile and whose most popular use has been speculation. But Facebook’s proposed digital currency, Libra, will be backed by fiat money and designed to maintain a stable value.
