And it’s a hybrid mix of hydrogen and electric power.

Global mining company Anglo American is experimenting with hydrogen to power the giant mining trucks.

Mining trucks consume 35.3 gallons (134 liters) of diesel per hour with their enormous weight of around 220 metric tonnes and therefore emitting vast amounts of carbon dioxide into the atmosphere.

In order to reduce the mining industry’s carbon footprint, Anglo American is focused on mining trucks.

The company is collaborating with several partners, such as Engie, NPROXX, First Mode, Williams Advanced Engineering, Ballard, ABB, Nel, and Plug Power, to develop a hybrid mining vehicle, fueled with hydrogen and electricity.

Thyme and oregano possess an anti-cancer compound that suppresses tumor development, but adding more to your tomato sauce isn’t enough to gain significant benefit. The key to unlocking the power of these plants is in amplifying the amount of the compound created or synthesizing the compound for drug development.

Researchers at Purdue University achieved the first step toward using the compound in pharmaceuticals by mapping its biosynthetic pathway, a sort of molecular recipe of the ingredients and steps needed.

“These contain important compounds, but the amount is very low and extraction won’t be enough,” said Natalia Dudareva, a Distinguished Professor of Biochemistry in Purdue’s College of Agriculture, who co-led the project. “By understanding how these compounds are formed, we open a path to engineering plants with higher levels of them or to synthesizing the compounds in microorganisms for .

Abstract: A central goal of condensed-matter physics is to understand how the diverse electronic and optical properties of crystalline materials emerge from the wavelike motion of electrons through periodically arranged atoms. However, more than 90 years after Bloch derived the functional forms of electronic waves in crystals [1] (now known as Bloch wavefunctions), rapid scattering processes have so far prevented their direct experimental reconstruction. In high-order sideband generation [2–9], electrons and holes generated in semiconductors by a near-infrared laser are accelerated to a high kinetic energy by a strong terahertz field, and recollide to emit near-infrared sidebands before they are scattered. Here we reconstruct the Bloch wavefunctions of two types of hole in gallium arsenide at wavelengths much longer than the spacing between atoms by experimentally measuring sideband polarizations and introducing an elegant theory that ties those polarizations to quantum interference between different recollision pathways. These Bloch wavefunctions are compactly visualized on the surface of a sphere. High-order sideband generation can, in principle, be observed from any direct-gap semiconductor or insulator. We thus expect that the method introduced here can be used to reconstruct low-energy Bloch wavefunctions in many of these materials, enabling important insights into the origin and engineering of the electronic and optical properties of condensed matter.

Rolls-Royce, the 115-year-old iconic British Engineering firm, has now achieved a new feat. After manufacturing world-class jet engines, it has left its mark in the electric aviation world.

Spirit of Innovation, a single-seat, electric-powered propeller plane built by Rolls-Royce, obliterated the zero-emission speed record, reaching over 556 kilometers per hour (345 mph) over a three-kilometer distance—and even maxing out at 623 kilometers per hour. This flight successfully smashed all previous records of electric planes which are environment friendly.

With a clarion call given by the COP26 on the need to cut emissions, Rolls-Royce has presented itself as a company that could earnestly provide that solution. With the aviation industry registering a record number of flights after a year of lockdowns, the emissions are set to grow further.

Infection during pregnancy with elevated levels of the cytokine IL-17a may yield microbiome alterations that prime offspring for aberrant immune responses, mouse study suggests.

Though many people with autism spectrum disorders also experience unusual gastrointestinal inflammation, scientists have not established how those conditions might be linked. Now MIT

MIT is an acronym for the Massachusetts Institute of Technology. It is a prestigious private research university in Cambridge, Massachusetts that was founded in 1861. It is organized into five Schools: architecture and planning; engineering; humanities, arts, and social sciences; management; and science. MIT’s impact includes many scientific breakthroughs and technological advances.
