Quantum repeaters: From quantum networks to the quantum internet

Posted by in categories: internet, quantum physics

Quantum technology is now at a point where practical work can begin on creating the quantum internet. However, numerous challenges must be overcome before this vision becomes a reality. A global-scale quantum internet requires the development of the quantum repeater, a device that stores and manipulates qubits while interacting with or emitting entangled photons. This review examines different approaches to quantum repeaters and networks, covering their conceptual frameworks, architectures, and current progress in experimental implementation.

Can We Train Massive Neural Networks More Efficiently? Meet ReLoRA: the Game-Changer in AI Training

Posted by in categories: robotics/AI, transportation

In machine learning, larger networks with increasing parameters are being trained. However, training such networks has become prohibitively expensive. Despite the success of this approach, there needs to be a greater understanding of why overparameterized models are necessary. The costs associated with training these models continue to rise exponentially.

A team of researchers from the University of Massachusetts Lowell, Eleuther AI, and Amazon developed a method known as ReLoRA, which uses low-rank updates to train high-rank networks. ReLoRA accomplishes a high-rank update, delivering a performance akin to conventional neural network training.

Scaling laws have been identified, demonstrating a strong power-law dependence between network size and performance across different modalities, supporting overparameterization and resource-intensive neural networks. The Lottery Ticket Hypothesis suggests that overparameterization can be minimized, providing an alternative perspective. Low-rank fine-tuning methods, such as LoRA and Compacter, have been developed to address the limitations of low-rank matrix factorization approaches.

Nanotechnology approaches for creating biodeterioration-resistant wood

Posted by in categories: nanotechnology, sustainability

Emerging technologies such as nanotechnology can provide efficient approaches by which new materials with broad functions, such as durable and fire-retardant properties, can be developed and subsequently used for the treatment of wood materials.

In a study published in the Journal of Bioresources and Bioproducts, an international team from New Zealand (Scion) and China (Northeast Forestry University) report a review that nanotechnology-based methods can be employed to mitigate these weaknesses and create durable, sustainable wood materials.

These wood nanotechnologies also can be employed to develop wood products with antimicrobial surfaces for various applications. Furthermore, analytical tools used in nanoscience and nanotechnology enable the precise study of wood structure and its components on a nanometer scale, particularly those aspects that can affect wood products’ biodeterioration resistance properties.

A Grave Warning About Antarctica Is Encoded in Octopus DNA

Posted by in categories: biotech/medical, health

Ocean bays that pinch West Antarctica are home to two distinct populations of Turquet’s octopus (Pareledone turqueti). The shared secrets of their ancestors do not bode well for the future health of our planet.

A new DNA analysis of the two geographically separated octopus populations indicates they were once part of one big family.

This direct historical connection suggests that around 125,000 years ago, the massive 2.2 million cubic kilometer (530,000 cubic mile) West Antarctic Ice Sheet (WAIS) that separates the two bays had fully collapsed into the sea.

Discovery of new material is ‘giant leap’ towards clean energy production and colonisation of Mars

Posted by in categories: energy, nanotechnology, space, sustainability

Scientists have developed a new material from a mineral abundant on Mars that they claim could open the door to sustainable habitation on the red planet.

Researchers assessed the potential of a type of nanomaterials – ultrasmall components thousands of times smaller than a human hair – for clean energy production and building materials on Mars.

The study, published in the journal Advanced Functional Materials, found that a material typically considered a waste product by NASA can be altered to provide clean energy and sustainable electronics.

Scientists just had a 20-minute ‘conversation’ with a humpback whale

Posted by in categories: alien life, innovation

Researchers have had an unprecedented and exceptional encounter with a humpback whale, allowing them to learn more about humpback whale communication systems. The encounter happened earlier this year when a group of researchers known as Whale-SETI held a 20-minute “conversation” with a humpback named Twain.

The conversation is heavily detailed in a paper published in the journal Peer J and it showcases the first conversation between humans and humpback whales using “humpback language.” To pull off such a wonderful breakthrough, researchers used a recorded humpback contact call to get Twain’s attention. From there, the whale responded with a greeting signal and began to circle their boat.

The Mystery of the Paulding Light: Unveiled by Science

Posted by in categories: engineering, science, space

The Paulding Light, a perplexing glow in the Michigan sky, has fueled folklore with its eerie nightly appearances since the 1960s. What was once thought to be a ghostly signal has turned into a case study for scientific inquiry. A team of Michigan Tech students, led by Jeremy Bos, a PhD candidate in electrical engineering, undertook a methodical investigation to expose the truth behind the spectral luminance that intrigued both locals and visitors in Michigan’s Upper Peninsula.

Their rigorous scientific approach involved telescopes, spectrographs, and atmospheric modeling, which demystified the paranormal claims. By observing the phenomenon through a telescope, the researchers identified the lights as nothing more than the headlights and taillights of vehicles on a distant stretch of US Highway 45. This was further supported by spectral analysis, confirming the automotive origin of the lights. The team’s findings pointed to atmospheric conditions and the geography of the Paulding area, which caused the vehicle lights to refract and create the illusion of the unexplained Paulding Light.

Despite the logical explanations provided by these dedicated students, the Paulding Light’s allure remains undiminished. The legend continues to attract those drawn to the supernatural, demonstrating the human fascination with mystery over the mundane. The Paulding Light stands as a symbol of our enduring attraction to the unexplained, a reminder that sometimes, even when the truth is revealed, the legend never dies.

MIT’s Breakthrough: Cooling Homes Without Electricity

Posted by in categories: climatology, habitats, sustainability

Let’s face it: on a scorching hot day, the sweet hum of an air conditioner feels like a lifeline. But what if that lifeline is actually tying us into a knot of environmental woes?

It turns out, our reliance on air conditioning is heating up the planet just as much as it’s cooling our homes.

Enter a team of ingenious researchers from MIT with a revolutionary idea: aerogel. This isn’t just another tech buzzword; it’s a potential game-changer in our fight against climate change.
