The Titan submersible, lab-grown chicken, and GM’s wayward Cruise robotaxis made our annual list of the worst in tech.
Welcome to our annual list of the worst technologies.
The company launched 23 of its Starlink internet satellites on a Falcon 9 rocket that had flown 18 times before, breaking its own record for the most flights by a single booster.
SpaceX has achieved a new milestone in its quest to reuse rockets and reduce the cost of spaceflight. The company launched 23 Starlink internet satellites on a Falcon 9 rocket that had flown 18 times before, breaking its record for the most flights by a single booster.

Joe McEntee visits the Lawrence Berkeley National Laboratory to learn about QUANT-NET’s plan to create a quantum network tested for distributed quantum computing applications in the US. Joe McEntee visits Lawrence Berkeley National Laboratory (Berkeley Lab) in California to check out progress on the enabling quantum technologies.
A team of researchers, led by Professor Hyong-Ryeol Park from the Department of Physics at UNIST has introduced a technology capable of amplifying terahertz (THz) electromagnetic waves by over 30,000 times. This breakthrough, combined with artificial intelligence (AI) based on physical models, is set to revolutionize the commercialization of 6G communication frequencies.
Collaborating with Professor Joon Sue Lee from the University of Tennessee and Professor Mina Yoon from the Oak Ridge National Laboratory, the research team successfully optimized the THz nano-resonator specifically for 6G communication using advanced optimization technology.
The research findings have been published in the online version of Nano Letters.
The Human Genome Project promised medical advances from knowledge of the DNA inside nearly every human cell. Now, around 20 years later, nucleic acids — the building blocks of DNA and RNA — are at the centre of powerful approaches to new medicines.
Have you ever wondered what the universe looked like before the first stars were born? How did these stars form and how did they change the cosmos? These are some of the questions that the James Webb Space Telescope, or Webb for short, will try to answer. Webb is the most powerful and ambitious space telescope ever built, and it can observe the infrared light from the most distant and ancient objects in the universe, including the first stars. The first stars are extremely hard to find, because their light is very faint and redshifted by the expansion of the universe. But Webb has a huge mirror, a suite of advanced instruments, and a unique orbit that allows it to detect and study the first stars. By finding the first stars, Webb can learn a lot of information that can help us understand the early history and evolution of the universe, and test and refine the theoretical models and simulations of the first stars and their formation processes. Webb can also reveal new and unexpected phenomena and raise new questions about the first stars and their role in the universe. Webb is opening a new window to the cosmic dawn, where the first stars may shine. If you want to learn more about Webb and the first stars, check out this article1 from Universe Today.

A single, extremely cold atom could play the role of two slits in the classic double-slit experiment from quantum physics, something that was previously thought to be impossible.
Researchers at the University of Helsinki have uncovered a mechanism that instantaneously generates DNA palindromes, potentially leading to the creation of new microRNA genes from noncoding DNA sequences. This discovery, which was made while studying DNA replication errors and their impact on RNA molecule structures, offers new insights into gene origins.
The complexity of living organisms is encoded within their genes, but where do these genes come from? Researchers at the University of Helsinki resolved outstanding questions around the origin of small regulatory genes, and described a mechanism that creates their DNA palindromes. Under suitable circumstances, these palindromes evolve into microRNA genes.
