POSTECH has created a solid oxide fuel cell (SOFC) that not only adds life to drones but can also replace lithium-ion batteries in smartphones.

Battery life. Two words that can turn anyone who owns an electronic device into a total wreck. But scientists at POSTECH may have found the solution to prevent you from having a panic attack each time you see your device almost out of juice.

Prof. Gyeong Man Choi and his Ph.D. student Kun Joong Kim have developed a miniaturized solid oxide fuel cell (SOFC) powerful enough to extend the flying time of drones to more than an hour. And that’s just the start.

Forget bionic knees, this company will let you grow a new one.

BEIJING China’s production and sale of electric cars will more than double this year, the industry minister said on Sunday.

More than 300,000 electric cars were sold in China last year, Miao Wei, the head of the Ministry of Industry and Information Technology told reporters on the sidelines of the annual meeting of parliament on Sunday.

The reliability, mileage and lifespan of electric batteries needs improvement and China needs to speed up the installation of electric car charging stations, Miao said.

Biohacker Andrew Pelling has figured out a way to create living, functional biological objects that don’t exist in nature — without deliberately modifying DNA in any way. In one experiment, h…

Researchers in Finland have figured out a way to reliably make quantum computers — technology that’s tipped to revolutionise computing in the coming years — even more powerful. And all they had to do was throw common sense out the window.

You’re almost certainly reading this article on a classical computer — which includes all phones, laptops, and tablets — meaning that your computer can only ever do one thing at a time. It reads one bit, then the next bit, then the next bit, and so on. The reading is lightning fast and combines millions or billions or trillions of bits to give you what you want, but the bits are always read and used in order.

So if your computer searches for the solution to a problem, it tries one answer (a particular batch of ones and zeros), checks how far the result is from the goal, tries another answer (a different batch), and repeats. For complicated problems, that process can take an incredibly long time. Sometimes, that’s good. Very clever multiplication secures your bank account, and faster or more efficient equation-solvers put that in jeopardy.

A quantum computer has been built that can find prime factors, potentially signalling the beginning of the end for cryptography that relies on the multiplication of large prime numbers, such as RSA encryption.

Going back to the start, how did you come to studying Theoretical Physics?

As with most people my path was determined by a series of choices involving random factors. I liked mathematics and physics at school, and did well in the olympiads, but I liked also literature, history, etc. At the age of fourteen I choose a technical-type high school oriented at nuclear disciplines, as popular then as they are despised by many these days, probably because it was one of the most difficult and challenging ones.

The way from there to the Technical University was straightforward. Since I have the need to understand things from the first principles, I drifted gradually towards theoretical physics and it was only natural that in the middle of my studies, corresponding roughly to the bachelor degree nowadays, I ended up at the Theoretical Physics Department of the Charles University, where I subsequently graduated.
