German nanotechnology specialist attocube says its attoDRY800 cryostat enables quantum scientists to “reclaim the optical table” and focus on their research not the experimental set-up.

Twin-track innovations in cryogenic cooling and optical table design are “creating the space” for fundamental scientific breakthroughs in quantum communications, allowing researchers to optimize the performance of secure, long-distance quantum key distribution (QKD) using engineered single-photon-emitting light sources.

In a proof-of-concept study last year, Tobias Heindel and colleagues in the Institute of Solid State Physics at the Technische Universität (TU) Berlin, Germany, implemented a basic QKD testbed in their laboratory. The experimental set-up uses a semiconductor quantum-dot emitter to send single-photon pulses along an optical fibre to a four-port receiver that analyses the polarization state of the transmitted qubits.

LYNCHBURG, Va (WSET) — Strangers may soon be able to use your Wi-Fi — It’s all through Amazon Sidewalk.

It’s an internet-sharing network for Amazon Echo, Ring and Tile devices. Officials say it’s a way to use WiFi from neighboring homes that also have Amazon products.

Randy Marchany a cybersecurity expert with Virginia Tech feels this is another way to collect information. He says it’s specifically picking up on user habits and whereabouts.

Morocco-born Dr Rachid Yazami has lived all over the world, thanks to an invention he made in his first year as a PhD student – the graphite anode – which is one of the key components that make lithium-ion batteries perform so well.

With electric vehicles on the rise, he believes the invention will soon take you everywhere, too.

Yazami’s story starts in the mid-1970s when scientists knew that graphite could help to form molten or powdered lithium into a usable energy storage material but struggled to turn it into a product. In 1983 Yazami and co-author Ph. Touzain cracked the problem by using a solid polymer electrolyte.

History seems to keep repeating when it concerns nuclear fission. Hopefully, no one gets hurt.


The US government has spent the past week assessing a report of a leak at a Chinese nuclear power plant, after a French company that part owns and helps operate it warned of an “imminent radiological threat,” according to US officials and documents reviewed by CNN.

The warning included an accusation that the Chinese safety authority was raising the acceptable limits for radiation detection outside the Taishan Nuclear Power Plant in Guangdong province in order to avoid having to shut it down, according to a letter from the French company to the US Department of Energy obtained by CNN.

Despite the alarming notification from Framatome, the French company, the Biden administration believes the facility is not yet at a “crisis level,” one of the sources said.

High levels of labile iron have been linked to neurodegenerative disorders like Alzheimer’s before. Similarly, copper is another mineral typically shielded safely in a protein, yet thoroughly capable of making a mess of our brains in labile form.


Set aside every scrap of iron inside a human body and you might have enough to fashion a nail or two. As for copper, you’d be lucky to extract just enough to make a small earring.

Scarce as they are, these two metals are necessary for our survival, playing essential roles in human growth and metabolism. But one place we wouldn’t expect to find either is clumped inside our brain cells.

However, for people with the neurodegenerative disorder Alzheimer’s disease, something seems to be turning these elements into microscopic ingots.

Tesla’s NEW Giga Press Is a BIG Game Changer Tesla and big things are inseparable. Be it ambition, idea, or more tangible items, Tesla would rather go big. Perhaps that is due to the many successes the company has racked up in the short time it has existed or just the personality of the CEO, Elon Musk. Whatever the case, Tesla tends to come along and fundamentally change how things are done, just like with its Giga Press. What is a Giga Press and how does it work? Why is it a game changer in the auto making business? Welcome to Tech Archives.

What is a Giga Press?

They are giant machines made by IDRA Group based out in Italy. The name was actually coined by IDRA, not Tesla. Their purpose is die casting large parts in a single piece. If you have a head for figures, Giga Presses produce a clamping forces of between 55000 kilonewtons and 61000 kilonewtons. Giga Presses are the biggest casting machines to ever exist. To get a sense of how massive these machines are, they weigh 410 to 430 tonnes. That is the equivalent of five Space Shuttles. They are the sizes of houses, at 20 meters by 7.5 meters by 6 meters and require dozens of flatbed trucks for transportation. And to get a sense of what a Giga Press does, think of a small plastic toy car. You would notice the chassis is made from a single piece. That is what a Tesla Giga Press tries to achieve. Instead of a chassis that uses up to 70 bolted and welded parts as it is done by all other car makers, the new Tesla chassis will be one solid piece of engineering feat. Tesla’s NEW Giga Press Is a BIGI Game Changer Buckle up because on this channel we will go through all things Tesla, ev, and Elon Musk. Stay tuned for the latest Tesla news and Tesla updates.
