A hybrid microscope allows scientists to simultaneously image the full 3D orientation and position of an ensemble of molecules, such as labeled proteins inside cells. The microscope combines polarized fluorescence technology, a valuable tool for measuring the orientation of molecules, with a dual-view light sheet microscope (diSPIM), which excels at imaging along the depth (axial) axis of a sample.

Agricultural fertilizers are critical for feeding the world’s population, restoring soil fertility and sustaining crops. Excessive and inefficient use of those resources can present an environmental threat, contaminating waterways and generating greenhouse gases such as nitrous oxide. Now, researchers have addressed those challenges with glass fertilizer beads. The beads control nutrient release, and the researchers say they’re environmentally compatible.

Researchers have developed a fully biobased hair conditioner using lignin gel emulsions, offering a sustainable and environmentally friendly alternative to conventional haircare products.

Artificial Intelligence (AI), particularly large language models like GPT-4, has shown impressive performance on reasoning tasks. But does AI truly understand abstract concepts, or is it just mimicking patterns? A new study reveals that while GPT models perform well on some analogy tasks, they fall short when the problems are altered, highlighting key weaknesses in AI’s reasoning capabilities.

Sweden’s Viking Age population appears to have suffered from severe oral and maxillofacial disease, sinus and ear infections, osteoarthritis, and much more. This is shown in a study in which Viking skulls were examined using modern X-ray techniques.

Safety critical components for aircraft and Formula 1 racing cars could one day be 3D printed via a new technique that substantially reduces imperfections in the manufacturing process.

Rapid, localized heat management is essential for electronic devices and could have applications ranging from wearable materials to burn treatment. While so-called thermoelectric materials convert temperature differences to electrical voltage and vice versa, their efficiency is often limited, and their production is costly and wasteful. Researchers have now used a 3D printing technique to fabricate high-performance thermoelectric materials, reducing production costs significantly.

An international research collaboration has overturned the long-standing belief that the atomic nucleus of lead-208 is perfectly spherical. The discovery challenges fundamental assumptions about nuclear structure and has far-reaching implications for our understanding of how the heaviest elements are formed in the universe.

Researchers have found that stars in the early universe may have formed from ‘fluffy’ molecular clouds. Using the ALMA telescope to observe the Small Magellanic Cloud — whose environment is similar to the early universe — they observed that about 60% of the observed clouds had the common filamentary structure, while the remaining 40% had a ‘fluffy’ shape. These results could provide new insights into the formation of stars in the universe.

A discovery offers new hope in the battle against pulmonary fibrosis, a debilitating lung condition that progressively makes it harder for patients to breathe. Scientists have pinpointed proteins in immune cells that, when blocked, could significantly reduce lung tissue scarring.
