Machine vision, a rapidly evolving field where cameras, sensors, and algorithms collaborate to interpret the world and execute specific tasks, has traditionally relied on transferring data over long distances for analysis. This process, however, is too slow for many real-time applications. “The world is entering an AI era, but AI is very time- and energy-exhaustive,” said Lu Fang, associate professor at Tsinghua University’s Department of Electronic Engineering. In today’s fast-paced world, machine vision now requires on-device data processing, known as edge computing, to enable quicker decision-making.

Researchers at MIT, led by Damian Stefaniuk, have developed a groundbreaking material that could revolutionize energy storage. By combining water, cement, and carbon black—a highly conductive material commonly used in car tires—Stefaniuk and his team created a supercapacitor with the potential to significantly impact renewable energy storage.

Unlike lithium-ion batteries, supercapacitors are not ideal for long-term energy storage but excel at rapid charging and discharging. This makes them an intriguing complement to conventional batteries. The novel carbon-cement supercapacitor developed by Stefaniuk’s team could alleviate pressure on the electrical grid by providing efficient storage solutions for green energy, which often fluctuates throughout the day.

A new trend in green technology focuses on converting energy from water or air into drinkable water. DrinkingMaker, an innovative company, is set to launch DrinkingWater, a solar-powered, multifunctional dispenser that extracts water from the air.

Amid the climate crisis and increasing water scarcity, DrinkingMaker drew inspiration from desert beetles and cacti to develop DrinkingWater, an advanced air-to-water (AWD) dispenser. This new technology is designed to yield up to 19 liters of water per day and offers optional mineral-rich filter cartridges, allowing users to customize their mineral water to personal preferences.

Cirrus Therapeutics, the University of Bristol, and London’s Global University Institute of Ophthalmology have unveiled a revolutionary treatment for age-related macular degeneration (AMD), the leading cause of vision loss among older adults. Highlighted on the cover of Science Translational Medicine, this groundbreaking research shows that increasing levels of a specific protein, IRAK-M, in retinal cells could offer a highly effective therapy for AMD.

AMD severely impacts vision, starting with blurred sight or a central black dot, which can expand, leading to complete central vision loss. Currently, around 200 million people worldwide suffer from AMD, with projections suggesting this number will rise to 288 million by 2040 due to aging populations. The exact cause of AMD is complex, involving a mix of aging, environmental, and lifestyle factors.

A new heat-to-energy converter has achieved a record-breaking efficiency of 44%, significantly higher than the average steam turbine’s 35%. This innovative thermophotovoltaic (TPV) cell marks a significant advancement towards sustainable, grid-scale renewable energy storage.

As renewable energy prices plummet, the challenge lies in their intermittency. Critics often point out the variability of solar and wind power, asking, “What happens at night or when the wind isn’t blowing?” The solution lies in effective energy storage systems, which can bridge the gap during periods of low renewable energy generation. Traditional options include lithium-ion batteries and emerging technologies like iron-air, water-in-salt, and flow batteries. However, one of the most promising methods involves storing energy as heat.

A Swiss biocomputing startup, FinalSpark, has launched an innovative online platform called Neuroplatform, providing remote access to 16 human brain organoids. This groundbreaking service claims to be the world’s first online platform delivering access to biological neurons in vitro. Notably, FinalSpark states that bioprocessors like those used in Neuroplatform consume a million times less power than traditional digital processors, promising a significant reduction in the environmental impacts of computing.

FinalSpark asserts that its Neuroplatform is capable of learning and processing information. Its remarkably low power consumption could drastically cut the energy costs associated with computing. According to a recent research paper by FinalSpark, training a single large language model (LLM) like GPT-3 required approximately 10 GWh—around 6,000 times the annual energy consumption of an average European citizen. By deploying bioprocessors, such immense energy expenditure could be significantly reduced.

Having numerous glass surfaces in your home can make rooms feel bright and open, but they often bring in too much heat and expose you to prying eyes. A groundbreaking new metamaterial offers a solution by enhancing transparency, ensuring privacy, cooling interiors, and even cleaning itself. This innovation is known as the Polymer-based Micro-photonic Multi-functional Metamaterial (PMMM).

PMMM is a thin film that can be easily applied to standard glass. Its unique properties stem from the microscopic pyramid patterns etched on its surface, each just 10 microns wide. These tiny pyramids scatter 73% of incoming light, giving the material a frosted appearance while still allowing 95% light transmittance, compared to the 91% typical of regular glass. This feature ensures a brighter, more comfortable environment for both people and plants.
