Physicists 3D-print a Christmas tree made of pure ice using only water and vacuum A team at the University of Amsterdam has managed to 3D-print an 8-centimeter Christmas tree made entirely of pure ice, using no freezers or cryogenic gases—only water and a vacuum chamber.

Ten People Who Shaped Science in 2025: From a Trailblazing Baby to Guardians of Integrity In 2025, science moved forward not just through big discoveries, but through the courage of individuals willing to push boundaries, challenge power, and protect evidence-based decisions. Nature’s annual “Nature’s 10” list captures that human side of science with ten stories that connect deep space, deep oceans, gene editing, and global health.

MIT Artificial Tendons Supercharge Muscle-Powered Robots MIT engineers have created hydrogel artificial tendons that link lab-grown muscles to robotic structures, enabling biohybrid grippers to operate three times faster and up to 30 times stronger than previous tendonless designs. This breakthrough slashes the tissue needed, skyrockets the power-to-weight ratio, and paves the way for "living" robots that adapt, grow stronger, and self-repair outside the lab.?

Chernobyl Fungus: Space Radiation Shield Picture a black fungus growing toward radiation in Chernobyl like it's its favorite snack. In 1991, microbiologist Nelli Zhdanova found Cladosporium sphaerospermum on Reactor 4 walls, packed with melanin that protects it and seems to turn gamma rays into energy via "radiosynthesis." In 2007, Ekaterina Dadachova and Arturo Casadevall showed it grows faster under radiation, exhibiting radiotropism.?

French universal law predicts how most objects shatter French researchers have introduced a universal mathematical law that describes how objects fragment when they break, whether they are brittle solids like glass and ceramics or liquid structures such as droplets and bubbles. When scientists count how many fragments appear in each size range and plot those data, they consistently see the same type of curve, almost independent of the material or the specific breaking event.?

More stable perovskite–silicon solar cells A team at the National University of Singapore has reported a key improvement in the operational stability of perovskite–silicon tandem solar cells, seen as one of the most promising technologies to surpass the efficiency limits of current photovoltaic modules. These devices use a self-assembled monolayer (SAM) to connect the perovskite absorber to the silicon cell, but this layer had been identified as a weakness at elevated temperatures. The current work analyses the degradation mechanism in detail and proposes a new formulation of the contact layer that is more resistant to heat.?

THE HIDDEN PROBLEM BEHIND THE PROLIFERATION OF OFFSHORE WIND TURBINES In this section of DYNA, we have frequently reported on the efforts being made to find appropriate recycling for the blades removed from operating wind turbines (see https://www.revistadyna.com/noticias-de-ingenieria/el-primer-alabe-totalmente-reciclable-de-aerogenerador), although the results so far have not been encouraging: thousands of them are already piling up in landfills with no specific destination.

THE ETERNAL RETURN OF THE HYPERLOOP More than ten years have passed since the visionary Elon Musk published his proposal for the much talked about tubular transport which, apart from having already had centuries of tests and experiences, had only consolidated itself as a modest means of movement for documents and/or parcels that other more modern means had ended up condemning to oblivion.
