New heat-shrinking method integrates electronic circuits on irregular shapes
Most electronics are built on flat, stiff boards, which makes it incredibly difficult to fit them onto curved and irregular shapes we find in the real world, such as human limbs or curved aircraft wings. While flexible electronics have made some progress, they are often not durable enough or are too complex to manufacture for everyday use.
But now scientists from Tianjin University and Tsinghua University in China have developed a way to integrate high-performance circuits into irregular 3D surfaces. Their findings are published in the journal Nature Electronics.

Cannot overstate my hatred for breadboards. Yeah sure they’re fine for circuits with < 10 components, but as soon as you have *any* part density.
Every component is liable to just *not* make a good connection, and every time you jam your fingers in there to fix it you knock another component out of its connection. You go to fix that one and you’ll *never guess* what happens next.
This is not a breadboard safe space. Perf-board supremacy.

A recollection- Visiting Col. Leslie King
( Image created by AI has no resemblance with any real life property)
One of my happy childhood memories, when I was about 10 years old lad, has always been those rare visits to Col. Laslie King’s household along with my father. Col. King was my father’s fellow amateur radio enthusiast and a friend. He used to stay in a bungalow allotted to him by Indian Army southern command, in Pune Cantonment area somewhere near today’s Dr. Koyaji Road. To add to my excitement of the visit to his house, there was always that pillion seat ride on my father’s AJS motor bike.
Col. Leslie king must have been much elder to my father, who was in his late thirties then. However, he used to be so friendly with us that I never realized it then. He was a great Amateur Radio enthusiast (HAM) and actively participated in all their activities. His call sign was VU2AK. He never believed in buying gear (Radio receiving and transmitting equipment) and was always keen to build his own gear (home-brewed stuff). His posting in Pune perhaps helped him, as lots of WWII electronic equipment left over by Allied forces in Pune Air Force station was being scrapped and sold in local market. He had many friends in Air Force, and he would know what stuff is going to be sold in advance. I remember giving him very exclusive items to my father such as Klystrons and a small 2-inch CRT tube, as gifts.
(An Amateur Radio enthusiast’s shack)
My father was also a keen Amateur Radio enthusiast (Call sign VU2EJ) and that was probably the only connection to their friendship. They would discuss for hours their home brewed stuff, and I would watch them fascinated, without saying even a word. SSB (Single side band) was the latest thing in HAM radio then and they would discuss circuits, parts, tubes for that.
“Leslie uncle”, as I used to call him then, had a very specious bungalow. There were a large veranda and and a hall/ There were two wings on the sides. His Amateur Radio station or shack was in the right wing and was full of electronics stuff, old ARL magazines and notebooks. His wife Audrey was a typical army wife (XYL in HAM jargon). Perfect in manners and most gracious. I was supposed to call her “aunty”, but she always insisted to my embarrassment, that I must address her as Audrey only. In any case, my conversational skills in English, at that time, were almost equal to none and I mostly kept quiet in her presence. King’s only son then, had gone to England and I remember Audrey telling me that he does not want to return to India and wanted to settle there. She could not talk or communicate with her son often as telephones were just primitive. So she had finally decided to become an Amateur Radio enthusiast (HAM) herself and earned a call sign VU2YL. In this way she could communicate with her son for as long as possible. My only regret now is that I could never communicate with Audrey properly with my extremely poor English speaking skills.
Audrey made wonderful cakes. Sponge cake was one of her best recipes. My mother always wanted to learn to make cakes, and Audrey gladly taught her recipes. With Audrey’s guidance my mother became expert in making delicious cakes. During my visits to King household, Audrey’s cakes used to be a prime attraction.
Leslie Uncle was really my father’s Guru in HAM world and guided him to build his basic stuff, Antenna etc. He also suggested purchasing the Hallicrafters radio receiver, which my father did. Hallicrafters model SX-28 was very popular with Indian HAMS at that time, with both Leslie Uncle and my father owning it. Another popular radio was RCA AR-88.
I recently found from net that ‘Leslie uncle’ was later promoted as a Brigadier and posted to Bangalore. He continued his HAM activity there and made improvements to his SSB gear. After he moved to Bangalore, my father lost all contact with him, except for occasional talk on radio. I have no information about when he …

Best F1 circuits. Racing that deserves an overhaul
Some tracks feel like sacred ground. Others feel like they are one dull race away from being a debate topic again.
This article looks at the best F1 circuits with a sharp eye on what makes great racing today. Flow, overtaking zones, strategy variety, and the way a track punishes small mistakes. It also asks the uncomfortable question. Which iconic venues still deliver, and which ones might need real updates to keep up with the modern cars.
That does not mean tearing down history. It means protecting it by making sure the racing stays alive. A small change to a corner entry or a reworked DRS approach can turn a predictable Sunday into a classic.
The piece balances nostalgia with honesty, which is exactly how fans talk about this sport. You can love a track and still admit the show has gone flat there lately.
If you want a list that respects the legends while pushing the conversation forward, this one is worth your time.

Electricity is the closest thing we have to, if not, magic
Think about how electrons flow, how we harness their properties, how we are able to share information, all just from these things that we have never seen.
You point a remote at the TV and it obeys your commands - that is literally a wand!
Studying electrical engineering is like attending Hogwarts.

ALTMemristors achieve stable resistance values tied to fundamental constants of nature
Researchers at Forschungszentrum Jülich, together with international collaborators, have demonstrated for the first time that memristors—novel nanoscale switching devices—can provide stable resistance values directly linked to fundamental constants of nature. This paves the way for electrical units such as electrical resistance to be traced back far more simply and directly than it has been possible to date. By contrast, conventional, quantum-based measurement technology is so demanding that it can only be carried out in a few specialized laboratories worldwide.
The paper is published in the journal Nature Nanotechnology.
Since 2019, all base units of the International System of Units (SI)—including the meter, second, and kilogram—have been based on fundamental natural constants. For example, the kilogram, which was once based on the “prototype kilogram,” is now linked to Planck’s constant h. A meter is defined by the speed of light, and a second by the oscillation of the cesium atom.
