Equitable and accessible education in life sciences, bioengineering, and synthetic biology is crucial for training the next generation of scientists. Here the authors present the CRISPRkit, a cost-effective educational tool that enables high school students to perform CRISPR experiments affordably and safely without prior experience, using smartphone-based quantification and an automated algorithm for data analysis.

The idea of Dyson Spheres was a radical proposal by the physicist Freeman Dyson, an enormous shell of material enveloping a star. Dyson’s idea may be over half a century old, but interest in looking for such objects has only grown in the decades since. But how would such structures work? Are they physically even possible? And what might someone use them for? Today, we dive into the physics of Dyson spheres. Written & presented by Prof. David Kipping. Edited by Jorge Casas.

Nvidia’s upcoming artificial intelligence chips will be delayed by three months or more due to design flaws, a snafu that could affect customers such as Meta Platforms, Google and Microsoft that have collectively ordered tens of billions of dollars worth of the chips, according to two people who help produce the chip and server hardware for it.
Nvidia this week told Microsoft, one of its biggest customers, and another large cloud provider about a delay involving the most advanced AI chip in its new Blackwell series of chips, according to a Microsoft employee and another person with direct knowledge.
Electrically powered artificial muscle fibers (EAMFs) are emerging as a revolutionary power source for advanced robotics and wearable devices. Renowned for their exceptional mechanical properties, integration flexibility, and functional versatility, EAMFs are at the forefront of cutting-edge innovation.
A recent review article on this topic was published online in the National Science Review (“Emerging Innovations in Electrically Powered Artificial Muscle Fibers”).

Weather and climate experts are divided on whether AI or more traditional methods are most effective. In this new model, Google’s researchers bet on both.
Baidu’s novel self-reasoning AI framework aims to enhance language model reliability, potentially eliminating ‘hallucinations’ and setting new standards for AI accuracy and transparency.
It seems that Silicon Valley giants, AAA game developers, and other companies desperately clinging to the AI trend and trying to integrate the technology into any product they own will soon have to rethink their marketing strategies, as a new study conducted by researchers from Washington State University indicates that using terms like “AI” or “artificial intelligence” in product descriptions can negatively impact sales.
To explore the impact of including “AI” in goods and service descriptions on consumers’ purchase intentions, the team conducted six experiments and surveyed over a thousand people, discovering that the use of these terms decreases purchase intention and lowers emotional trust, leading to what any company fears the most – diminishing sales numbers.
Furthermore, the researchers found that putting artificial intelligence in the spotlight can be even more detrimental when it comes to high-risk products – those consumers typically think twice about buying, such as expensive gadgets and medical services – compared to low-risk items, primarily because of the greater likelihood of incurring monetary losses or facing health risks.
Injuries, infection and inflammatory diseases that damage the spinal cord can lead to intractable pain and disability. Some degree of recovery may be possible. The question is, how best to stimulate the regrowth and healing of damaged nerves.
At the Vanderbilt University Institute of Imaging Science (VUIIS), scientists are focusing on a previously understudied part of the brain and spinal cord —white matter. Their discoveries could lead to treatments that restore nerve activity through the targeted delivery of electromagnetic stimuli or drugs.
As in the brain, the spinal cord is made up nerve cell bodies (gray matter), which process sensation and control voluntary movement, and axons (white matter), fibers that connect nerve cells and which project to the rest of the body.
