Twisting optical fiber creates a robust new pathway for light

Light powers everything from communications to sensing, yet even tiny imperfections can scatter it and weaken signals. To address this, a team led by the University of Bath—working with the University of Cambridge and international partners—has developed a new structure that keeps light flowing smoothly even through bends, twists or damage, with the potential to operate over unprecedented distances.

How the humble silkworm could help us discover new anti-aging treatments

When scientists want to study aging and how to slow it down, they often turn to microscopic worms or lab mice among other models. The former are too different from humans, while the latter are expensive and take too long to study. But there's a new model in town that can potentially help us wind the clock back, and that is the silkworm (Bombyx mori).

The 'Little red dots' observed by Webb were direct-collapse black holes

The James Webb Space Telescope (JWST) was designed to look back in time and study galaxies that existed shortly after the Big Bang. In so doing, scientists hoped to gain a better understanding of how the universe has evolved from the earliest cosmological epoch to the present. When Webb first trained its advanced optics and instruments on the early universe, it discovered a new class of astrophysical objects: bright red sources that were dubbed "Little Red Dots" (LRDs). Initially, astronomers hypothesized that they could be massive star-forming regions, but this was inconsistent with established cosmological models.

Photosynthesis: Study reveals how minerals are involved in homeostasis of chloroplasts

Plants fix 258 billion tons of CO2 in their chloroplasts through photosynthesis every year. For these cell organelles to work properly, they require certain minerals—particularly ions of the metals iron (Fe), manganese (Mn), copper (Cu), and zinc (Zn). Disruptions of ion homeostasis impair photosynthesis and thus growth and yields. A team with members from Munich, Bochum, Columbia (MO), and Saarbrucken, led by LMU biologist Professor Hans-Henning Kunz has now deciphered the chloroplast ionome—the totality of metal ions in the chloroplast—of various plant species.

Nanotubes with lids mimic real biology

When water and ions move together through channels only a nanometer wide, they behave in unusual ways. In these tight spaces, water molecules line up in single file. This forces ions to shed some of the water molecules that normally surround them, leading to the unique physics of ion transport. Biological channels are especially adept at this behavior, often choreographing channel openings and closings to achieve complex behaviors such as signals in the nervous system.

Gold 'supraballs' nearly double solar energy absorption in tests

Sunbeams contain a lot of energy. But current technology for harvesting solar power doesn't capture as much as it could.

Applying a layer of supraballs onto a commercially available electricity converter demonstrated that the technology nearly doubled solar energy absorption compared to traditional materials.

Epigenetic switch found to halt fat cell formation in adipose tissue

Metabolic diseases such as obesity, fatty liver, and insulin resistance are rapidly increasing worldwide, but fundamental methods to regulate the process of fat formation remain limited. In particular, once adipocytes (fat cells) are formed, they are difficult to reduce, making treatment challenging. A research team from KAIST has discovered the existence of a switch that prevents fat formation. This discovery elucidates how an epigenetic switch, which regulates gene activity without altering the DNA sequence itself, functions during the process of adipogenesis, presenting new possibilities for the precise control of obesity and metabolic diseases in the future.
