2025 is … was the international year of quantum science and technology. Yes because quantum tech is increasingly important, but especially because quantum mechanics was invented 100 years ago this year. In 1925, our strangest true theory went from being a peculiar set of ideas to describe some funny results from experiments, to a full-blown theoretical framework that overturned how we think reality really works. So today, as the centenary year approaches its end I want to take you on a little journey through what may be the most paradigm-destroying several months in scientific history.

Wind-powered robot could enable long-term exploration of hostile environments

Researchers at Cranfield University have created WANDER-bot, a low-cost, 3D-printed robot that is powered by wind energy. Designed to spend long durations in hostile, windy environments such as certain deserts, polar regions or even other planets, WANDER-bot doesn’t need a battery to power movement, enabling longer operations without having to pause and recharge.

Movement accounts for around 20% of battery use in most robots, so running on natural energy makes WANDER-bot an efficient solution for long-term exploration or mapping of unknown terrains. As a result, any electronic elements added to future versions for data collection or transmission purposes could have their own smaller, lighter power source. Using natural energy also counters the issue of performance degradation over time in traditional power sources, such as solar cells and radioisotope thermoelectric generators.

Designed by Dr. Saurabh Upadhyay and Sam Kurian, Research Associate in Space Engineering, the robot uses parts that are entirely 3D printed, with the design deliberately simple to allow for quick repair and replacement. This means that, in theory, you could print and construct WANDER-bot anywhere and make replacement parts in situ as needed, removing the need for time-consuming and costly resupply missions.

Researchers uncover gut-liver serotonin pathway that limits nanoparticle and viral delivery

A new study has for the first time elucidated the gut-liver immune regulatory axis jointly maintained by intestinal commensal bacteria and the intestinal endocrine system, and uncovered the fundamental mechanism underlying the body’s nonspecific clearance of drug delivery carriers. It provides a universal solution to the core problem plaguing the delivery field for decades, significantly improves the delivery efficiency and therapeutic effect of tumor-targeted therapy, mRNA therapy, gene editing and other treatments, and blazes a new trail for the clinical translation of biomedical delivery technologies.

The research team led by Professors Wang Yucai, Zhu Shu and Jiang Wei from the University of Science and Technology of China (USTC) published their research paper titled “Commensal-driven serotonin production modulates in vivo delivery of synthetic and viral vectors” in Science on March 19.

What Happens When A Black Hole Dies and the End of the Universe

An exploration of the question of what happens when a back hole evaporates and ultimately what that means for the end of the universe, and what that end might be like.
