“IL-33 is a protein produced by various cell types in the body and is particularly abundant in the central nervous system (brain and spinal cord),” says lead researcher, Eddy Liew from the University of Glasgow in the UK. “We found that injection of IL-33 into aged APP/PS1 mice rapidly improved their memory and cognitive function to that of the age-matched normal mice within a week.”

Before we go any further, we should make it clear that these results are restricted to mice only, and at this stage, we have no idea if they will translate at all in humans with Alzheimer’s.

And the odds aren’t great — one study put successful translation of positive results in mice to humans at a rate of about 8 percent, so we can never get too excited until we see how things fare in human trials.

Whether it’s hay fever, food allergies, or asthma that plagues you, there’s no denying that our immune system can be a real punishment when it’s not working properly.

Which is why it’s so exciting to hear that researchers might have just come up with a system that could, in theory, put an end to all allergies — simply by forcing our bodies to recognise harmless objects, such as peanuts or pollens, as friend, rather than foe.

I know what you’re thinking — that sounds too good to be true, right? Because scientists have been trying to find a way to stop our immune system freaking out over harmless things, such as cat hair and pollen, for decades, and so far, nothing’s really stuck.

Many think author, inventor and data scientist Ray Kurzweil is a prophet for our digital age. A few say he’s completely nuts. Kurzweil, who heads a team of more than 40 as a director of engineering at Google, believes advances in technology and medicine are pushing us toward what he calls the Singularity, a period of profound cultural and evolutionary change in which computers will outthink the brain and allow people—you, me, the guy with the man-bun ahead of you at Starbucks—to live forever. He dates this development at 2045.

Raymond Kurzweil was born February 12, 1948, and he still carries the plain, nasal inflection of his native Queens, New York. His Jewish parents escaped Hitler’s Austria, but Kurzweil grew up attending a Unitarian church. He worshipped knowledge above all, and computers in particular. His grandmother was one of the first women in Europe to earn a Ph.D. in chemistry. His uncle, who worked at Bell Labs, taught Ray computer science in the 1950s, and by the age of 15, Kurzweil was designing programs to help do homework. Two years later, he wrote code to analyze and create music in the style of various famous composers. The program won him the prestigious Westinghouse Science Talent Search, a prize that got the 17-year-old an invitation to the White House. That year, on the game show I’ve Got a Secret, Kurzweil pressed some buttons on a data processor the size of a small car. It coughed out original sheet music that could have been written by Brahms.

After earning degrees in computer science and creative writing at MIT, he began to sell his inventions, including the first optical character recognition system that could read text in any normal font. Kurzweil knew a “reading machine” could help the blind, but to make it work, he first had to invent a text-to-speech synthesizer, as well as a flatbed scanner; both are still in wide use. In the 1980s Kurzweil created the first electronic music keyboard to replicate the sound of a grand piano and many other instruments. If you’ve ever been to a rock concert, you’ve likely seen the name Kurzweil on the back of a synthesizer.

It may sound like sci-fi. But millions and millions of dollars are pouring into projects to mine asteroids and the moon. And with a space gold rush comes space pirates.

With trillions of dollars worth of minerals lying just under the moon’s surface or spinning around the solar system inside asteroids, space mining is big business.

Well, big potential business. No one has dug nickel out of an asteroid or scooped any tantalum from the lunar dust—at least not for profit. Before space miners can get drilling, they need to invent specialized industrial robots, set up orbital outposts and—arguably most importantly—convince investors, workers, and prospective buyers that space minerals are worth the cost and effort of mining them.
