Concerned about the war Ukraine? You’re not alone. Historian Yuval Noah Harari provides important context on the Russian invasion, including Ukraine’s long history of resistance, the specter of nuclear war and his view of why, even if Putin wins all the military battles, he’s already lost the war.

Circa 2013 o,., o! Unlimited cell division. Basically this means a possibility for unlimited cell division throughout the human body if used in crispr.


Whole-genome sequencing of the widely used HeLa cell line provides a nucleotide-resolution view of a greatly mutated and in some places shattered genome.

Last year, a team of former SpaceX engineers launched Californian marine startup Arc with a plan to develop a luxury electric cruiser with “far superior range, acceleration and performance than any boat in its class.” Now a pre-production Arc One has spent a day of testing on Lake Arrowhead ahead of deliveries to the first customers later in the year.

The first boat out of the company’s factory in Los Angeles is being aimed squarely at the luxury end of the market, and will be produced in very limited numbers.

The spec sheet for the Arc One is actually pretty thin, but the development team has recently upped the power of the electric motor to 500 hp (373 kW) for a top speed of 40 mph (34 knots/64 km/h). The battery size has also been increased by 10 percent to 220 kWh – that’s “three times the capacity of a Tesla Model Y” and is reckoned big enough for users to stay out on the water for between three and five hours per charge, though high speeds will drain the battery quicker than cruising at lower speeds.

Hydrogen is already a key component of chemical industrial processes and in the steel industry. So making clean hydrogen to use in those industrial processes is critical to reducing carbon emissions, says Jake Stones at market research firm Independent Commodity Intelligence Services (ICIS).

But as an energy source itself, hydrogen’s big advantage is its versatility according to Sunita Satyapal, who oversees hydrogen fuel cell technology for the Department of Energy.

“It’s often called the Swiss Army knife of energy,” she says.

(TNS) — The legal tug-of-war over development of waterfront land in Baltimore’s Westport neighborhood has tilted in favor of a high-speed maglev train operator seeking to build a passenger station on the site where a developer separately proposed housing.

The Court of Special Appeals, the state’s second-highest court, granted the appeal of Baltimore Washington Rapid Rail LLC, which is planning a $10 billion project to link Washington and Baltimore and eventually New York with a superconducting magnetic levitation rail system.

The opinion clears the way for Rapid Rail to pursue its eminent domain lawsuit against Westport property owner Stonewall Capital, prolonging a monthslong dispute.
