High-intensity interval training (HIIT) has become very popular; alternating short periods of intense anaerobic exercise with recovery periods, it is designed to help to decrease body fat, increase strength and endurance, and improve healthspan in protocols that last approximately half an hour.

But these days, even finding half an hour can be tricky – enter CAROL Bike, an exercise bike designed around Reduced Exertion HIIT (REHIT) and AI-personalization, meaning an effective workout can be delivered in just 5 minutes.

Longevity. Technology: Developed in collaboration with leading exercise researchers, CAROL Bike not only improves fitness, but increases VO₂, reduces blood pressure and decreases the risk of diabetes. Given CAROL Bike’s foundation being scientific studies, rather than just ‘feel the burn’ or ‘if it hurts, it must be working’, we were intrigued. We sat down with CAROL Bike’s cofounder and CEO Ulrich Dempfle, who leveraged his background in mechanical engineering to develop the world’s only Reduced Exertion HIIT (REHIT) bike.

Target validation is a crucial step in pre-clinical drug discovery workflows that builds confidence on the identification of a genetic target as relevant to a disease. With recent advancements, CRISPR serves as a particularly powerful tool for this process, as it enables researchers to accurately modify genes and determine their function in a variety of experimental systems.

One scientist leveraging CRISPR gene editing in this way is Dr. Panos Zalmas, Head of the Open Targets Validation Lab based at the Wellcome Sanger Institute, whose work focuses on discovering and validating new putative disease targets for the development of safe and effective medicines.

In this SelectScience® interview, we speak with Zalmas to learn how he is working to improve the rate of target adoption into drug discovery pipelines across therapy areas such as oncology, neurodegeneration, and immunology and inflammation. Here, Zalmas explains the importance of gene editing in his target validation workflows and highlights how CRISPR technologies in particular are key to the success of drug discovery.

The notion of black holes is one that invokes terror and dread. They’re inescapable! They devour everything! Nothing ever comes out!

The accuracy of these beliefs falls on the spectrum of debatable to incorrect. And a pair of physicists has now calculated how proverbial blood might be wrung from the black hole stone. According to Zhan-Feng Mai and Run-Qiu Yang of Tianjin University in China, teeny tiny black holes could theoretically be used as a source of power.

Their calculations find that these ultradense objects could work as rechargeable batteries and nuclear reactors, providing energy on the scale of gigaelectronvolts.

That’s good news. Maybe there’s gonna be fewer super bugs springing up.


Researchers have developed a method that identifies bacteria easily, cheaply and more precisely than before. This can help reduce use of antibiotics.

Far too many antibiotics are used around the world. As a result, bacteria are becoming resistant.

Curing bacterial diseases is becoming more difficult than before, because antibiotics are perhaps our foremost weapons in the fight against them.

The brain-computer interface (BCI) space continues to rise in notoriety, and a number of players are throwing their hats in the ring.

Such technologies could enable users to control a computer with their brain, or even go beyond that. Countless immobile people someday could control a mouse cursor, keyboard, mobile device/tablet, wheelchair or prosthetic device by only thinking.

Big names have already established their presence in the space. Elon Musk’s Neuralink continues to make headway, while Bill Gates-and Jeff Bezos-backed Synchron has an innovative catheter-delivered implant. Blackrock Neurotech, which has a next-generation BCI, has been implanting its Utah Array in patients since 2004.
