An important piece of SpaceX's new Starship megarocket just got its first workout. The first vacuum Raptor — the in-space version of Starship's Raptor engine — blazed up in a debut test at SpaceX's development facility in McGregor, Texas, company representatives announced via Twitter last night (Sept. 24).

With personal protective equipment still in short supply, researchers at the University of Cincinnati examined what common household fabrics might work best as a face covering. Next to a single-use N95 respirator or surgical mask, UC found the best alternative could be made by a hungry little caterpillar. Silk face masks are comfortable, breathable, and repel moisture, which is a desirable trait in fighting an airborne virus.

A new study reveals how video games can influence cognitive changes even after years of not playing them.

America’s worsening climate change problem is as polarized as its politics. Some parts of the country have been burning this month while others were underwater in extreme weather disasters. The already parched West is getting drier and suffering deadly wildfires because of it, while the much wetter East keeps getting drenched in mega-rainfall events, some hurricane-related and others not. Climate change is magnifying both extremes, but it may not be the only factor, several scientists told The...

Nearly 8,000 Facebook users die daily. By the end of this century, Facebook will become the world’s biggest virtual graveyard as there will be more profiles of dead people than of living users. Facebook is just one of the several social media platforms. Twitter, Instagram, WhatsApp, Snapchat, Reddit and others have flooded us, garnering millions of users.

The company just gave itself two decades to reach zero emissions. Can it put both customers and the climate first? The vast Illinois factory floor that will produce electric delivery vans for Amazon.com Inc. is starting to fill up. Battery and chassis assembly here. Tire storage there. A titanic, three-story metal press.

In 1965, Gordon Moore, a co-founder of Intel, forecast that computing would increase in power and decrease in price exponentially. For decades what later became known as Moore’s Law proved true, as microchip processing power roughly doubled and costs dropped every couple of years. But as power increased exponentially, so did the heat produced by packing billions of transistors atop a chip the size of a fingernail.

On Saturday, Twitter once again labeled one of President Donald Trump’s tweets with a public interest notice -- this time because it violated the social media platform’s “Civic Integrity Policy" for encouraging "people to potentially vote twice," according to the social media platform. “This Tweet violated the Twitter Rules about civic and election integrity,” the notice said. “However, Twitter has determined that it may be in the public’s interest for the Tweet to r...

You know that clip of Steve Carell from The Office where he’s shouting “No, God! No, God, please no! No! No! Nooooooooo!” That’s how I feel about Amazon’s announcement that it’s adding a new service to Alexa for landlords. It’s called Alexa for Residential that, according to Amazon, “makes it easy for property managers to set up and manage Alexa-powered smart home experiences throughout their buildings.”

Religion does not help us to explain nature. It did what it could in pre-scientific times, but that job was properly unseated by science. Most religious laypeople and even clergy agree: Pope John Paul II declared in 1996 that evolution is a fact and Catholics should get over it. No doubt some extreme anti-scientific thinking lives on in such places as Ken Ham’s Creation Museum in Kentucky, but it has become a fringe position. Most mainstream religious people accept a version of Galileo’s div...

Two space companies are teaming up on a planned 2022 mission that could help open up the off-Earth economy. California-based Momentus and Made In Space Europe (MIS EU) have finalized a memorandum of understanding to develop the flight to Earth orbit, the companies announced last week.

The Michael Moore-produced ‘Planet of the Humans’ faced a coordinated suppression campaign led by professional climate activists backed by the same ‘green’ billionaires, Wall Street investors, industry insiders and family foundations skewered in the film.

The cast of The Princess Bride will reunite virtually for a reading of the script of the 1987 classic, as a virtual fundraiser for the Democratic Party of Wisconsin.

The livestreamed event will be held at 4 p.m. PT on September 13.

“I was at home and that scary red monster thing from that stupid Looney Tunes show was hanging around,” reads the dream diary of Izzy, a teenage girl. “There were lots of them trying to get in and I was scared to death.”

But it won’t be easy.

Toronto Raptors head coach Nick Nurse has been named the NBA coach of the year.

The president’s insatiable need to traffic in rumor and conspiracy blows larger holes in our shared reality with each passing day.
