Inspired by nature: Leaftronics pave way for biodegradable electronics

Posted by in categories: mobile phones, sustainability

A research team headed by Prof. Karl Leo at TUD Dresden University of Technology have developed an innovative, nature-inspired solution that could revolutionize the electronics industry: “Leaftronics.” This innovative approach leverages the natural structure of leaves to create biodegradable electronic substrates with enhanced properties and offers a sustainable, efficient, and scalable solution to the global-waste problem. These findings have now been published in the journal Science Advances.

Electronic devices, from toys to smartphones, consist of circuits. Specific substrates are used to manufacture these circuits. In commercial electronics, these are printed circuit boards (PCBs) made of glass fiber-reinforced epoxy resin.

Most of these materials are not recyclable, let alone biodegradable. Given the sheer volume of electronic waste of more than 60 million tons per year (of which over 75% is not collected worldwide), there is an urgent need for sustainable alternatives.

PlayStation at 30: How Sony’s gray box conquered gaming

Posted by in category: entertainment

Japanese electronics giant Sony is set to celebrate 30 years since it launched the PlayStation console, the little gray box that catapulted the firm into the gaming big league.

PlayStation was Sony’s first foray into the world of video games and when it hit the shelves in Japan on December 3, 1994, the company needed to sell one million units to cover its costs.

In the end, the gadget became a legend, selling more than 102 million units, helping to launch many of the industry’s best-loved franchises and positioning Sony as a heavyweight in a hugely lucrative sector.

High-dose vitamin C: Promising treatment may extend survival of pancreatic cancer patients

Posted by in category: biotech/medical

A study published in the November issue of Redox Biology has found that adding intravenous, high-dose vitamin C to a chemotherapy regimen doubled the survival of patients with late-stage, metastatic pancreatic cancer from eight months to 16 months.

“This is a deadly disease with very poor outcomes for patients. The median survival is eight months with treatment, probably less without treatment, and the five-year survival is tiny. When we started the trial, we thought it would be a success if we got to 12 months survival, but we doubled overall survival to 16 months. The results were so strong in showing the benefit of this therapy for patient survival that we were able to stop the trial early,” explains Joseph J. Cullen, MD, FACS, a professor of Surgery and Radiation Oncology at the University of Iowa, in a statement to StudyFinds.

The study consisted of 34 patients with stage 4 pancreatic cancer who were randomized to two groups. One group received standard chemotherapy (gemcitabine and nab -paclitaxel). The other group received the same chemotherapy plus intravenous infusions of 75 grams of vitamin C three times a week.

Dynamics of self-hybridized exciton–polaritons in 2D halide perovskites

Posted by in categories: solar power, sustainability

Basically I believe that this could be the answer for solar panels having super high output as exciton polariton energy is very powerful.


Self-hybridized exciton–polaritons are shown to enable sub-bandgap absorption and emission in 2D perovskites. The energy absorbed by the perovskites are also found to transfer to few-layer graphene in a heterostructure.

New Study Shows How Light Sleep Improves Your Cognition

Posted by in categories: biotech/medical, neuroscience

Although it is widely recognized that sleep boosts cognitive performance, the neural mechanisms underlying this effect—especially those associated with non-rapid eye movement (NREM) sleep—are still not well understood.

A new study by a team of researchers at Rice University and Houston Methodist’s Center for Neural Systems Restoration and Weill Cornell Medical College, coordinated by Rice’s Valentin Dragoi, has nonetheless uncovered a key mechanism by which sleep enhances neuronal and behavioral performance, potentially changing our fundamental understanding of how sleep boosts brainpower.

The research, published in Science, reveals how NREM sleep — the lighter sleep one experiences when taking a nap, for example — fosters brain synchronization and enhances information encoding, shedding new light on this sleep stage. The researchers replicated these effects through invasive stimulation, suggesting promising possibilities for future neuromodulation therapies in humans. The implications of this discovery potentially pave the way for innovative treatments for sleep disorders and even methods to enhance cognitive and behavioral performance.

Silicon chips are no longer sustainable. Here’s what’s next

Posted by in categories: computing, sustainability

The classic strategy of continually shrinking transistors in silicon chips to create faster, more powerful computers is starting to fail us.

“Even though silicon works at these extremely small dimensions, the energy efficiency required to do one calculation has been going up, and this makes it highly unsustainable,” Deep Jariwala, an engineering professor at the University of Pennsylvania, told the Wall Street Journal in 2022. “Energy-wise it doesn’t make sense anymore.”
