Optical tweezers prove Einstein right

Researchers have successfully measured the back-flow effect in Brownian motion, a phenomenon Einstein predicted but overlooked 100 years ago. The discovery uses optical tweezers technology to detect this effect, confirming a key aspect of Brownian motion theory.

Fingerprints in the sky explained

Researchers used elliptic integrals to predict polarisation patterns in skylight, finding that singularities play a vital role in shaping the overall pattern. The study provides a simple and beautiful explanation for this natural phenomenon.

Physicists reveal first 'nanoflowers'

Researchers at Cambridge University have successfully grown nanometer-scale wires into flower-like structures, which can be used as water-repellent coatings and a base for new solar cells. The unique nanostructures are created by controlling the growth process of silicon-carbon materials using liquid metals.

Freedom in the conduct of science

The International Council for Science (ICSU) examines current threats to scientific freedom and proposes recommendations to address visa restrictions and promote international collaboration. ICSU emphasizes the need for scientists to recognize their responsibilities and provide adequate information for processing visa applications.

Jurors' comprehension of scientific evidence

Recent research shows that jurors' comprehension of scientific evidence is a significant challenge, particularly when dealing with complex and nuanced facts. Dr. Solan identifies several problems, including diminished juror comprehension, inappropriate influence by expert credentials, and varying understandings of causation concepts.
