Batteries are getting better.

Bai and his team believe they have come up with a solution to these shortcomings, by doing away with the anode and incorporating a thin layer of copper foil instead. This sits on the anode side of the battery's current collector, which gathers the free electrons as the battery is discharged and channels them into the device being powered.

“We’ve found that the minimal is maximum,” Bai said. “No anode is the best anode.”

Battery Myths Busted: Full Charging

A full charge of the battery does not mean it does not have any more battery cells that can be charged.

The Lithium ions inside the lithium cobalt oxide layer are designed by manufacturers so that only half of it is used, to ensure repeat charging and discharging for maximum cycles

Artificial eyes look to the future

Bionic eyes have been a mainstay of science fiction for decades, but now real-world research is beginning to catch up with far-sighted storytellers. A raft of technologies is coming to market that restore sight to people with different kinds of vision impairment.

Israeli surgeons implanted the world’s first artificial cornea into a bilaterally blind, 78-year-old man. When his bandages were removed, the patient could read and recognise family members immediately. The implant also fuses naturally to human tissue without the recipient’s body rejecting it.

Elon Musk

"I tend to approach things from a physics framework. And physics teaches you to reason from first principles rather than by analogy. So I said, OK, let’s look at the first principles. What is a rocket made of? Aerospace-grade aluminum alloys, plus some titanium, copper, and carbon fiber. And then I asked, what is the value of those materials on the commodity market? It turned out that the materials cost of a rocket was around 2 percent of the typical price—which is a crazy ratio for a large mechanical product."
