The LAVO bike from StudioMOM is the world’s first hydrogen bike, requiring no heavy batteries, particulates, or CO₂ emissions for operation.

Nowadays, it seems bikes are the preferred mode of transportation in crowded cities. Traffic is no joke and public transportation has seen some major changes since the onset of the COVID-19 pandemic, so people are hitting the streets with shiny electric and portable bicycles. While bikes are generally more environmentally friendly than cars and trucks, they come with their own list of setbacks. Becoming the world’s first hydrogen bike, the LAVO bike from StudioMOM is a small solution to a big problem.

The contraption can charge the car in 40 hours. 🚗

The heavy trailer is bound to reduce the car’s range.

A constitution for Mars’ future government is further along than you think.

A constitution for a colonized Mars’ future government is further along than you think. Former SpaceX general counsel, David Anderman, tells us how it could work.

Your brain does not process information, retrieve knowledge or store memories. In short: your brain is not a computer by Robert Epstein + BIO.

Dubbed 4660 Nereus, or 1982 DB, this vaguely egg-shaped asteroid has a size making it taller than the Eiffel Tower and nearly twice as tall as the Washington Monument. It is set to pass by the planet on December 11 at a distance of approximately 3.9 million kilometers and at a speed of 6.578 km/s.

For comparison, the distance between the Earth and the Moon is about a thousandth of that – around 385,000 km. As such, despite being classified as a Potentially Hazardous Asteroid (PHA) due to its size and close proximity to Earth, it seems unlikely to pose a threat to the planet.

NASA is getting ready to launch a spacecraft to test an experimental method to deflect near-Earth objects, and you can participate in the mission by testing your own planetary defense know-how.

The space agency’s Double Asteroid Redirection Test (DART) mission is designed to test a “kinetic impactor” technique for deflecting any asteroid or comet that might otherwise impact Earth.

“It doesn’t sound like a lot when you look at the numbers, but those are completely preventable deaths,” Zane Zents, the lead software engineer for the Grain Weevil robot, told NTV News. “It’s something that in the 21st century I don’t think we should still be dealing with.”

The Grain Weevil: Zents’ fellow student Ben Johnson was studying electrical engineering at UNO when he received a special request from a farmer friend, Zach Hunnicutt.

“(He) said, ‘Hey, look, you guys build robots. Why don’t you build me a robot so I and my children never have to go into a grain bin again?’” Johnson told AgWeb in May.

A new database aims to make it easier than ever to access and search through the world’s massive trove of research papers.

Each year, millions of scientific and academic papers get published across thousands of journals. The majority of those papers lie behind paywalls, costing $9 to $30 (or more) to read. Finding them can be difficult: Tools like Google Scholar allow you to search for paper titles and keywords, but more specialized queries are difficult.

The General Index was designed to reduce those obstacles without breaking the law. Developed by the technologist Carl Malamud and his nonprofit foundation Public Resource, the free-to-use index contains words and phrases from more than 107 million research papers, comprising 8.5 terabytes when compressed.
