Summary: The pioneering “soleus pushup” effectively elevates muscle metabolism for hours, even when sitting.

From the same mind whose research propelled the notion that “sitting too much is not the same as exercising too little,” comes a groundbreaking discovery set to turn a sedentary lifestyle on its ear: The soleus muscle in the calf, though only 1% of your body weight, can do big things to improve the metabolic health in the rest of your body if activated correctly.

An information engine uses information to convert heat into useful energy. Such an engine can be made, for example, from a heavy bead in an optical trap. A bead engine operates using thermal noise. When noise fluctuations raise the bead vertically, the trap is also lifted. This change increases the average height of the bead, and the engine produces energy. No work is done to cause this change; rather, the potential energy is extracted from information. However, measurement noise—whose origin is intrinsic to the system probing the bead’s position—can degrade the engine’s efficiency, as it can add uncertainty to the measurement, which can lead to incorrect feedback decisions by the algorithm that operates the engine. Now Tushar Saha and colleagues at Simon Fraser University in Canada have developed an algorithm that doesn’t suffer from these errors, allowing for efficient operation of an information engine even when there is high measurement noise [1].

To date, most information engines have operated using feedback algorithms that consider only the most recent bead-position observation. In such a system, when the engine’s signal-to-noise ratio falls below a certain value, the engine stops working.

To overcome this problem, Saha and colleagues instead use a “filtering” algorithm that replaces the most recent bead measurement with a so-called Bayesian estimate. This estimate accounts for both measurement noise and delay in the device’s feedback.

French hydrogen specialist Hydrogène de France (HDF) is moving forward with its green hydrogen project in Swakopmund, a city located on the Namibian coast, in the administrative region of Erongo.

The company said it obtained new permits for the project from the Namibian authorities. “This important step in the authorization process confirms a favorable environment for the project. As a result, HDF Energy is moving closer to building the first green hydrogen power plant in Africa, among the first deployed by HDF Energy globally, ” said Nicolas Lecomte, HDF Energy’s director for southern Africa.

These wind turbines have the potential to produce more energy at lower cost.

This novel technology can be built in many ways, even like a snake.

The National Renewable Energy Laboratory (NREL) has revealed a breakthrough technology with wave energy. The lab claims that with this new technology, electricity can be produced from waves and even from clothes, and cars.

NREL — which specializes in the research and development of renewable energy, energy efficiency, energy systems integration, and sustainable transportation — has already taken out the patent of its unique distributed embedded energy converter technologies (DEEC-Tec).

Chinese researchers expect to significantly reduce the costs of commercial hypersonic travel with a novel engine using a combination of ethylene and coal powder, according to an article published by the South China Morning Post (SCMP) on Tuesday.

In tests conducted, a prototype using the affordable and efficient mixture produced shocks traveling at more than 2km (1.24 miles) per second, or six times the speed of sound, the scientists claimed in a new paper published in the China Ordnance Society’s peer-reviewed Acta Armamentarii journal on September.

A solar flare erupted from a departing sunspot on September 16, releasing a pulse of X-rays and extreme UV radiation which caused a shortwave radio blackout in Africa and the Middle East. Frequencies below 25 MHz were affected for up to an hour after the flare.

Solar flare strength is measured much like the Richter scale which measures earthquakes. Solar flares are classed A, B, C, M or X where each successive letter corresponds to a 10-fold increase in energy output. A-class solar flares are barely above background radiation emission from the sun.

Spaceweather.com reports that the September 16 solar flare, exploding out of sunspot AR3098, was an M8-class, meaning it was nearly an X-flare, the most powerful kind.

MIT students are part of the large team that achieved fusion ignition for the first time in a laboratory. Researchers around the world have been engaged in attempts to achieve fusion ignition in a laboratory for more than half a century. It is a grand challenge of the 21st century. An approach called inertial confinement fusion (ICF), which uses lasers to implode a pellet of fuel in a quest for ignition, has been the focus of the High-Energy-Density Physics (HEDP) group at MIT’s Plasma Science and Fusion Center. This group, including nine former and current MIT students, was crucial to a historic ICF ignition experiment performed in 2021. The results were published this year on the anniversary of that success.

Everything you need to know about red-light therapy!

Red light therapy might sound like something that you would file in your mind alongside homeopathic remedies, or maybe even pyramid power. A completely unproven, unsubstantiated fad sold to the uneducated masses who inexplicably posses more money than sense. However, as it turns out red light therapy might very well be more than the latest cosmetic fad.

What exactly is red light therapy?
