By exerting "crowd control" over mouse cells, scientists make progress towards engineering tissues
Genes aren't the sole driver instructing cells to build multicellular structures, tissues, and organs. In a paper published in Nature Communications, USC Stem Cell scientist Leonardo Morsut and Caltech computational biologist Matt Thomson characteriz.....»»
Plasma heating efficiency in fusion devices boosted by metal screens
Heating plasma to the ultra-high temperatures needed for fusion reactions requires more than turning the dial on a thermostat. Scientists consider multiple methods, one of which involves injecting electromagnetic waves into the plasma, the same proce.....»»

Quantum technologies are radically transforming our understanding of the universe. One emerging technology is macroscopic mechanical oscillators, devices that are vital in quartz watches, mobile phones, and lasers used in telecommunications. In the q.....»»
Molecular tool demonstrates how bad eggs are identified for destruction by reproductive system
The biological factory that produces reproductive cells has a robust quality control system to identify and eliminate eggs with chromosomal abnormalities. For years, cell biologists have sought to uncover the mechanisms behind this system, relying on.....»»
Apollo lunar mission samples reveal origins of lunar water and its connection to Earth"s early history
A team of international scientists has unveiled groundbreaking research on the origins of lunar water, offering insights that could reshape our understanding of the Earth-moon system and the broader solar system. Published in the journal Proceedings.....»»
Scientists document rich biodiversity along underexplored Chilean coastline
An international team of scientists on board a recent Schmidt Ocean Institute R/V Falkor (too) expedition surveyed nearly 20 methane seeps, some of which are new discoveries, and four submarine canyon systems previously never before seen by humans......»»
Cellular RNA plays key role in antiviral defense, study finds
Scientists have uncovered a new role for a cell's own RNA in fending off attacks by RNA viruses. Some of the cell's RNA molecules, researchers found, help regulate antiviral signaling. These signals are part of the intricate coordination of immune re.....»»
Early warning tool may help control huge locust swarms
Desert locusts typically lead solitary lives until something—like intense rainfall—triggers them to swarm in vast numbers, often with devastating consequences......»»
Cenotectic concept redefines search for life on icy worlds
As NASA's Europa Clipper embarks on its historic journey to Jupiter's icy moon, Europa, Dr. Matt Powell-Palm, a faculty member at Texas A&M University's Department of Mechanical Engineering, has unveiled research that could transform our understandin.....»»
Easy tips to save money don"t always work. Here"s why.
Amid spending season and a plethora of articles listing ways to control your budget during these holidays, a Deakin University researcher warns there are no quick and easy solutions......»»
Scientists recreate molecular timers to control nanomachine activation rates
Living organisms monitor time—and react to it—in many different ways, from detecting light and sound in microseconds to responding physiologically in pre-programmed ways, via their daily sleep cycle, monthly menstrual cycle, or to changes in the.....»»
Optical spring enables programmable defect mode in new mechanical crystal
Mechanical crystals, also known as phononic crystals, are materials that can control the propagation of vibrations or sound waves, just like photonic crystals control the flow of light. The introduction of defects in these crystals (i.e., intentional.....»»
Molecular gardening: New enzymes discovered for protein modification pruning
Deubiquitinases (DUBs) are enzymes used by cells to trim protein modifications made from the protein ubiquitin, and thereby regulate proteins. Malfunctioning of DUBs could lead to diseases, including cancer and neurodegenerative disorders......»»
Top 10 plant and fungal species named new to science in 2024
Scientists from the Royal Botanic Gardens, Kew and their partners reveal their pick of the top 10 plants and fungi named new to science in 2024......»»
Researchers develop edible biofilm for extending fruit shelf life
With significant improvements in transportation technology, the accessibility of fresh food has considerably increased. However, this progress has been accompanied by escalating concerns about food waste during transportation and storage. Globally, a.....»»
Miniaturized all-fiber photoacoustic spectrometer for intravascular gas detection rivals lab-based systems
Miniaturized spectroscopy systems that can detect trace concentrations at the parts-per-billion (ppb) level are of the utmost importance in applications ranging from environmental monitoring and industrial process control to biomedical diagnostics. H.....»»
Massive volcanic eruptions did not cause the extinction of dinosaurs, say climate scientists
Massive volcanic eruptions on the Indian peninsula have long been proposed as an alternative cause for the demise of the dinosaurs. This phase of active volcanism took place in a period just before Earth was struck by a meteorite, 66 million years ag.....»»
Clouds obscure link between extreme rainfall and rising temperatures
Extreme rainfall is usually defined as the heaviest 5% of rain events in a specific area. As global air temperatures rise, scientists expect extreme rainfall to increase. This is because warmer air can hold more moisture. Recent examples of more extr.....»»
