ANOTHER OPTICAL BREAKTHROUGH COMPLEMENTING METALENSES. In addition to the ongoing revolution in optical science brought about by flat metalenses and single-photon image sensors, there is another parallel and complementing new dimension now added to the mix, which, according to this article, will allow telescopes as thin as a piece of paper.


Can you imagine one day using a telescope as thin as a sheet of paper, or a much smaller and lighter high-performance camera? Or no longer having that camera bump behind your smartphone?

In a paper published in Nature Communications, researchers from the University of Ottawa have proposed a new optical element that could turn these ideas into reality by dramatically miniaturizing optical devices, potentially impacting many of the applications in our lives.

To learn more about this project, we talked to lead author Dr. Orad Reshef, a senior postdoctoral fellow in the Robert Boyd Group, and research lead Dr. Jeff Lundeen, who is the Canada Research Chair in Quantum Photonics, Associate Professor in the Department of Physics at the University of Ottawa, and head of the Lundeen Lab.

Stefan Thomas really could have used a quantum computer this year.

The German-born programmer and crypto trader forgot the password to unlock his digital wallet, which contains 7002 bitcoin, now worth $265 million. Quantum computers, which will be several million times faster than traditional computers, could have easily helped him crack the code.

Though quantum computing is still very much in its infancy, governments and private-sector companies such as Microsoft and Google are working to make it a reality. Within a decade, quantum computers could be powerful enough to break the cryptographic security that protects cell phones, bank accounts, email addresses and — yes — bitcoin wallets.

Circa 2017 could be used on smartphones to scan the body for illnesses.


Medical techniques for looking inside our bodies have come a long way, but in the future it looks like doctors may be able to see absolutely everything going on under our skin.

Researchers have invented a new kind of camera that can actually see through structures inside the human body, detecting light sources behind as much as 20 centimetres (7.9 inches) of bodily tissue.

The current prototype, developed by researchers from the University of Edinburgh in the UK, is designed to work in conjunction with endoscopes – long, slender instruments that are often equipped with cameras, sensors and lights to peer inside hollow cavities inside the human body.

Mapping how humans move will help in future pandemics.


How people move around cities follows a predictable and universal pattern, scientist say, which will be crucial not only for urban planning but also controlling pandemics.

By analysing mobile-phone tracking data from across four continents, the team confirmed that people visit places more often when they don’t have to travel far to get there.

“We might shop every day at a bakery a few hundred metres away, but we’ll only go once a month to the fancy boutique miles away from our neighborhood,” says project leader Carlo Ratti, from the Massachusetts Institute of Technology (MIT).

Harvard University researchers have made a breakthrough in battery tech: a long-lasting solid-state lithium battery.

“A lithium-metal battery is considered the holy grail for battery chemistry,” researcher Xin Li told the Harvard Gazette.

Strong, cheaper, faster: Most of today’s electric vehicles (EVs) are powered by lithium-ion batteries, the same type of battery you’ll find in your laptop or smartphone.

Soon, the majority of portable PCs won’t need to be equipped with an ugly barrel jack and a proprietary power brick to charge. The USB Implementers Forum (USB-IF) has just announced that it’s more than doubling the amount of power you can send over a USB-C cable to 240 watts, which means you’ll eventually be able to plug in the same kind of multipurpose USB-C cable you currently use on lightweight laptops, tablets, and phones to charge all but the beefiest gaming laptops.


Extended Power Range.

As the world is running out of lithium, planet-friendlier batteries are waiting to hit the market. We are using up lithium, the essential metal in rechargeable batteries. Some experts estimate that there won’t be any lithium left by 2035, and some say that it may already disappear within four years. Who should lose sleep over this? Anyone with a smartphone, a laptop or an electric car. Without lithium, they would have to be plugged in at all times.

But it’s not just about comfort. Lithium also plays an important role in storing wind and solar energy, an increasingly important sector. Therefore, the world is in the midst of a battery revolution.

An iPhone app that estimates biological aging discovered that life expectancy has the capacity to be almost double the current norm.


GEYLANG, Singapore — Have you made any plans for the 22nd century yet? A new study finds you might want to think about it because it’s possible for humans to live to see their 150th birthday!

Scientists in Singapore have developed an iPhone app that accurately estimates biological aging. It discovered that life expectancy has the capacity to be almost double the current norm. The findings are based on blood samples from hundreds of thousands of people in the United States and United Kingdom.

The instrument, called DOSI, uses artificial intelligence to work out body resilience, the ability to recover from injury or disease. DOSI, which stands for dynamic organism state indicator, takes into account age, illnesses, and lifestyles to make its estimates.
