Two of my passions are electric bicycle projects and DIY solar powered projects. In fact I’ve written the book on both topics. So to see these two fields combined in one quirky-yet-awesome product totally made my week. I just hope you’re as excited as I am to dive into this strange electric bike/car contraption that boasts a heap of features from seating for two to a giant solar panel array offering nearly unlimited range!

It’s just one of many strange, awesome and fun-looking electric vehicles I’ve discovered while window shopping on the world’s most eclectic digital thrift store: Alibaba. And now it has the honor of officially becoming this week’s Awesomely Weird Alibaba Electric Vehicle of the Week!

We’ve seen solar powered electric bicycles before, but they’re usually designed with some serious pedaling requirements. The low power of even large-sized panels means that riders generally still have to provide some significant leg assist.

There are trillions of microbes in the human gastrointestinal tract, each of which expresses its own genome, and carries out a variety of biochemical processes. Gut microbes can generate a variety of molecules that can have a significant impact on human health, such as vitamins, specially modified bile acids, and short-chain fatty acids (SCFAs).

SCFAs have fewer than six carbon atoms, and are found in a few major forms, including acetate, propionate, and butyrate. When we eat fibers that are tough to digest, gut microbes metabolize them instead, and generate SCFAs. Many links have been found between butyrate and human health; it is thought to have roles in the maintainence of epithelial barriers, prevention of gut inflammation in the gut and colorectal cancer, and oxidative stress relief.

This article is almost a year old, yet still wildly interesting.

An MIT scientist developed a wearable BCI device that allows users to access the internet with their minds.

The wearable device records neural signals as and when a person hears or thinks of words.

Arnav Kapur, an India-born MIT student, has invented a device which can let you converse with machines and AI without speech, simply by ‘articulating words internally’

Don’t want Google’s experimental AI search feature embedded into your search pages? Too bad.

According to Search Engine Land, Google has started unleashing its AI-powered Search Generative Experience (SGE) product, which was previously available for users only on an opt-in basis, into the browsers of users who didn’t choose to partake in Google’s AI search experiment.

Google has defended the unsolicited SGE-ification of its platform, telling Search Engine Land that it’s thus far only incorporated SGE automatically into a “subset of queries” that take up a “small percentage of search traffic in the US” and arguing further that the rollout will allow them to glean feedback from the users who, again, didn’t elect to opt into the generative AI search service.

What non-invasive methods can be developed to kill viruses on site? This is what a recent study published in ACS Nano hopes to address as a team of international researchers have developed a silicon surface containing nanospikes capable of preventing viruses from replicating or killing them entirely. This study holds the potential to help develop a passive way of mitigating the spread of viruses within a myriad of environments, including scientific laboratories and healthcare facilities.

“Our virus-killing surface looks like a flat black mirror to the naked eye but actually has tiny spikes designed specifically to kill viruses,” said Dr. Natalie Borg, who is a senior lecturer in the STEM | Health and Biomedical Sciences at RIMT University and a co-author on the study. “This material can be incorporated into commonly touched devices and surfaces to prevent viral spread and reduce the use of disinfectants.”

For the study, researchers at the Melbourne Centre for Nanofabrication took inspiration from insects, some of which possess their own version of nanospikes on their wings that can damage fungi and bacteria. To produce the nanospikes, the team blasted smooth silicon wafers with ions, resulting in nanospikes measuring 290 nanometers in height and 2 nanometers thick, the latter of which is 30,000 times thinner than a human hair. They then tested their new material on the hPIV-3 virus, which is responsible for causing pneumonia and bronchitis, finding their nanospikes exhibited a 96 percent success rate in either preventing the virus from replicating or shredding them to pieces completely.
