Elon Musk says Twitter is recruiting just weeks after laying off half the company’s staff

Posted by in category: Elon Musk

Since then, the tech mogul and Tesla CEO has let further staff go, some through layoffs aimed at downsizing the company and others through more targeted firings.

But after scrambling to get rid of staff, Twitter is still now actually hiring, Musk said in a presentation to the company, slides from which he posted on Twitter.

“We’re recruiting,” the slide simply read.

Rolls-Royce tests hydrogen-fueled aircraft engine in aviation world first

Posted by in categories: energy, government, military

British engineer Rolls-Royce has successfully used hydrogen instead of conventional jet fuel to power a modern aircraft engine in a world first for the aviation industry, according to the company.

The ground test, which took place at a government test facility at Boscombe Down, used green hydrogen generated by wind and tidal power from the Orkney Islands in Scotland.

Rolls-Royce used a converted AE 2100-A turboprop engine that powers civil and military aircraft to conduct the test in partnership with easyJet.

In a first, Rolls-Royce and easyJet successfully test a hydrogen-powered aircraft engine

Posted by in categories: energy, transportation

The test is a stepping stone to achieving carbon neutrality by 2050.

In what can be considered a promising first step towards transforming the aviation industry to become carbon-neutral, a project led by Rolls Royce and easyJet has successfully tested a modern-day jet engine that runs solely on hydrogen.

The prototype for the experiment, which was conducted at a test facility at the Ministry of Defence Boscombe Down, U.K., was a commonly-used Rolls-Royce AE-2100A regional aircraft engine. The turbine was supplied with ‘green’ hydrogen, which was made by splitting water into its constituent components at European Marine Energy Centre in the Orkney Islands, U.K.

A new analysis of the early universe sheds new light on the “cosmic dawn” of the universe

Posted by in categories: energy, space

The absence of the 21-centimeter hydrogen line allowed scientists to determine specific properties of the earliest galaxies in the universe.

An international group of astronomers, led by scientists at the University of Cambridge, just shed new light on the cosmic dawn of the universe, a press statement reveals.

The cosmic dawn is a very early period of the universe, during which the first stars and galaxies formed. The researchers used data from India’s SARAS3 radio telescope to analyze this period of the cosmos and determine mass and energy output limits for the first stars and galaxies.

China’s solar observatory beams back its first image of our host star

Posted by in category: space travel

The ASO-S observatory, which launched in early October, captured an image of a solar flare eruption.

China’s recently launched Advanced Space-based Solar Observatory (ASO-S) beamed its first image back to Earth, a report from Space.com reveals. The new image shows an M-Class flare erupting on the Sun.

China’s ASO-S solar observatory launched to orbit aboard one of the China Aerospace and Technology Corporation’s (CASC’s) Long March-2C rockets on October 9. The country’s first dedicated solar observatory is positioned in a sun-synchronous orbit around Earth, flying at an altitude of approximately 430 miles (700 km).

In a first, researchers discovered a rare mineral that comes directly from Earth’s lower mantle

Posted by in category: education

This is “the first time that lower mantle minerals have ever been observed in nature.”

Researchers claim they have discovered a rare mineral that comes directly from Earth’s lower mantle-the region between the planet’s core and crust — in a new study published in Science.

However, thanks to a diamond-in which it was entrapped — the new mineral dubbed ‘davemaoite,’ managed to make the improbable voyage from at least 412 meters within the lower mantle.

For the first time, Tesla just completed a full load 500-mile trip with its Semi truck

Posted by in categories: Elon Musk, energy, sustainability, transportation

Tesla Semi carried 81,000 pounds for 500 miles on a single charge.

Just a few days before Tesla begins shipping the truck, Elon Musk has verified that Tesla Semi, the company’s Class 8 semi-truck, has successfully completed a crucial voyage.

Although there is no reason to question the outcome, it would be interesting to learn more about speed and energy usage. We are pretty interested in seeing some impartial vehicle tests.
