Researchers have demonstrated a new technique for self-assembling electronic devices. The proof-of-concept work was used to create diodes and transistors, and paves the way for self-assembling more complex electronic devices without relying on existing computer chip manufacturing techniques.

A theoretical study suggests that small black holes born in the early universe may have left behind hollow planetoids and microscopic tunnels, and that we should start looking within rocks and old buildings for them. The research proposes thinking both big and small to confirm the existence of primordial black holes, suggesting that their signatures could range from very large -- hollow planetoids in space -- to minute -- microscopic...

A new study increases our knowledge about the gut and the life of gut bacteria. The study shows, among other things, that changes in the gut environment have an impact on the composition and activity of gut bacteria. Ultimately, this may help explain why we all have different gut bacteria and probably also why we react differently to the same food. Read more ›

Scientists have a new way to use data from high-energy particle smashups to peer inside protons. Their approach uses quantum information science to map out how particle tracks streaming from electron-proton collisions are influenced by quantum entanglement inside the proton. The results reveal that quarks and gluons, the fundamental building blocks that make up a proton's structure, are subject to so-called quantum entanglement. Read more ›

A cancer therapy that prompts the body's immune defenses against viruses and bacteria to attack tumors can make patients more vulnerable to heart attack and stroke. A possible explanation for this side effect is that the treatment interferes with immune regulation in the heart's largest blood vessels, a new study suggests. Read more ›

Scientists have invented a liquid ink that doctors can print onto a patient's scalp to measure brain activity. The technology offers a promising alternative to the cumbersome process currently used for monitoring brainwaves and diagnosing neurological conditions. It also has the potential to enhance non-invasive brain-computer interface applications. Read more ›

Ketone bodies are not just about energy. These metabolites are powerful signaling molecules that have profound effects on the proteome and protein quality control in the brain. Scientists, working in mouse models of Alzheimer's disease and aging, and in the nematode C. elegans, reveal the ketone body -hydroxybutyrate interacts directly with misfolded proteins, altering their solubility and structure so they can be cleared from the brain through the process of...

An international team has tracked at BESSY II how heavy molecules -- in this case bromochloromethane -- disintegrate into smaller fragments when they absorb X-ray light. Using a newly developed analytical method, they were able to visualize the ultrafast dynamics of this process. In this process, the X-ray photons trigger a 'molecular catapult effect': light atomic groups are ejected first, similar to projectiles fired from a catapult, while the heavier... Read more ›

In June of 2024, the Endocrine Society, influenced by a substantial body of research conducted in recent years, published new clinical practice guidelines for the testing and supplementation of Vitamin D for the prevention of disease. These new recommendations included limiting vitamin D supplementation beyond the daily recommended intake to specific risk groups and advised against routine 25-hydroxyvitamin D [25(OH)D] testing in healthy individuals.

A team of astronomers has found that Venus has never been habitable, despite decades of speculation that our closest planetary neighbor was once much more like Earth than it is today. Read more ›

Where do you see patterns in chaos? It has now been demonstrated in the incredibly tiny quantum realm. Researchers detail an experiment that confirms a theory first put forth 40 years ago stating that electrons confined in quantum space would move along common paths rather than producing a chaotic jumble of trajectories.

A new study finds that two subtypes of pathogenic Escherichia coli (E. coli) produce five to 16 times more protective capsular 'slime' when Enterococcus faecalis (EF) is present. The finding could lead to targeted therapies for E. coli infections specific to dogs and poultry. Read more ›

As muscles age, their cells lose the ability to regenerate and heal after injury. Now, researchers have created the most comprehensive portrait to date of how that change, in mice, unfolds over time. Read more ›

Researchers developed a fully integrated photonic processor that can perform all the key computations of a deep neural network on a photonic chip, using light. This advance could improve the speed and energy-efficiency of running intensive deep learning models for demanding applications like lidar, astronomical research, and navigation. Read more ›

Researchers have created the smallest walking robot yet. Its mission: to be tiny enough to interact with waves of visible light and still move independently, so that it can maneuver to specific locations -- in a tissue sample, for instance -- to take images and measure forces at the scale of some of the body's smallest structures.

Some animals, such as the starlet sea anemone, can regenerate large parts of their body, even after major injuries. Researchers have shown this regeneration response involves cells and molecules in body parts far from the injury site and is directed towards restoring the animal's original shape. The study sheds new light on the fundamental importance of maintaining body shape in animals and enhances our understanding of the molecular pathways involved... Read more ›

A new study has provided further evidence that the deaths of 350 African elephants in Botswana during 2020 were the result of drinking from water holes where toxic algae populations had exploded due to climate change. Read more ›

Bacteria modify their ribosomes when exposed to widely used antibiotics, according to new research. The modified ribosomes have changes specifically in the regions where antibiotics latch on to and halt protein production. The study found this made the bacteria more resistant to the drugs. The subtle changes might be enough to alter the binding site of drug targets and constitute a possible new mechanism of antibiotic resistance. Read more ›
