Scientists use food industry byproduct to recover gold from electronic waste

Posted by in categories: chemistry, computing, food, mobile phones, sustainability

Transforming base materials into gold was one of the elusive goals of the alchemists of yore. Now Professor Raffaele Mezzenga from the Department of Health Sciences and Technology at ETH Zurich has accomplished something in that vein. He has not of course transformed another chemical element into gold, as the alchemists sought to do. But he has managed to recover gold from electronic waste using a byproduct of the cheesemaking process.

Electronic waste contains a variety of valuable metals, including copper, cobalt, and even significant amounts of gold. Recovering this gold from disused smartphones and computers is an attractive proposition in view of the rising demand for the precious metal.

However, the recovery methods devised to date are energy-intensive and often require the use of highly toxic chemicals. Now, a group led by ETH Professor Mezzenga has come up with a very efficient, cost-effective, and above all far more sustainable method: with a sponge made from a , the researchers have successfully extracted gold from electronic waste.

Scientists Develop a Technique to Protect a Quantum-era Metaverse

Posted by in categories: computing, encryption, quantum physics, security

A team of Chinese scientists introduced a quantum communication technique that they say could help secure Web 3.0 against the formidable threat of quantum computing.

Their approach, called Long-Distance Free-Space Quantum Secure Direct Communication (LF QSDC), promises to improve data security by enabling encrypted direct messaging without the need for key exchange, a method traditionally vulnerable to quantum attacks.

They add the approach not only enhances security but also aligns with the decentralized ethos of Web 3.0, offering a robust defense in the rapidly evolving digital landscape.

Study identifies multi-organ response to seven days without food

Posted by in categories: biotech/medical, food, health

New findings reveal that the body undergoes significant, systematic changes across multiple organs during prolonged periods of fasting. The results demonstrate evidence of health benefits beyond weight loss, but also show that any potentially health-altering changes appear to occur only after three days without food.

The study, published in Nature Metabolism, advances our understanding of what’s happening across the body after prolonged periods without food.

By identifying the potential health benefits from fasting and their underlying molecular basis, researchers from Queen Mary University of London’s Precision Healthcare University Research Institute (PHURI) and the Norwegian School of Sports Sciences provide a road map for future research that could lead to therapeutic interventions—including for people that may benefit from fasting but cannot undergo prolonged fasting or fasting-mimicking diets, such as ketogenic diets.

Is nuclear power the key to space exploration?

Posted by in categories: climatology, nuclear energy, space travel, sustainability

The Voyager 1 was launched in 1977. Almost 50 years later, it’s still going and sending back information, penetrating ever deeper into space. It can do that because it’s powered by nuclear energy.

Long a controversial energy source, nuclear has been experiencing renewed interest on Earth to power our fight against climate change. But behind the scenes, nuclear has also been facing a renaissance in space.

In July, the US National Aeronautics and Space Administration (NASA) and Defense Advanced Research Projects Agency (DARPA) jointly announced that they plan to launch a nuclear-propelled spacecraft by 2025 or 2026. The European Space Agency (ESA) in turn is funding a range of studies on the use of nuclear engines for space exploration. And last year, NASA awarded a contract to Westinghouse to develop a concept for a nuclear reactor to power a future moon base.

Real-time navigation is a useful tool for liver cancer procedures, according to new study

Posted by in category: biotech/medical

A University of Cincinnati Cancer Center study has found that real-time navigation is a useful tool for surgeons performing ablation procedures to destroy tumors in the liver.

The research, led by David A. Gerber, MD, is published in the journal JAMA Network Open.

Ablation, Gerber said, uses focused energy to kill in a similar way that focused energy in a microwave heats up food.

Hong Kong’s First Hydrogen Bus Hits The Streets Marking A Historic Step In #MissionZero

Posted by in category: space travel

Hong Kong’s public transportation landscape undergoes a revolutionary transformation with the deployment to service of a cutting-edge zero-emission hydrogen bus today. The first-ever hydrogen double deck bus has commenced service on our Route 20, marking a remarkable achievement and the next step in the transition of Hong Kong’s rich transport history as it takes to the road with customers on board, following our previous debut of Hong Kong’s first ever electric double deck bus two years ago. We eagerly anticipate reaching even more significant milestones in the near future, as the hydrogen bus will expand its operations to two additional routes in the next phase, underscoring our leading position in the public transport zero-emission space and making a further transformation for citizens and travellers in the vibrant heart of Kowloon.

Our hydrogen double deck bus, which is operated from and refuelled at Hong Kong’s first hydrogen refuelling station in our West Kowloon Depot, embarks on its first journey at 11:00am today. We were proud to welcome many joyful bus and transport enthusiasts on board the bus and share in the joy by handing out some certificates and gifts to commemorate this historic moment – “The Future is H2re”. Serving Route 20, the hydrogen bus will travel from Kai Tak (Muk On Street) to Cheung Sha Wan (Hoi Tat), offering in the initial phase a daily schedule of 6 to 8 trips.

Roger Ma, General Manager (Operations) of Citybus expressed his pride in the groundbreaking achievement of our “#MissionZero” campaign. “We take great pride as a company in serving the citizens of Hong Kong every day and in debuting Hong Kong’s first ever hydrogen double deck bus, which will shuttle through the bustling heart of Kowloon, encompassing the districts of Sham Shui Po, Yau Tsim Mong, and Kowloon City. In the next phase, our hydrogen bus will expand its service coverage to include Routes 20A and 22M.These three routes, include two prominent trunk routes, serve as core routes for Citybus, enabling us to gather further invaluable operational insights into real-world scenarios, including differing traffic conditions, weather factors and performance.”
