A new laboratory study suggests that human body lice are more efficient at transmitting Yersinia pestis, the bacterium that causes plague, than previously thought, supporting the possibility that they may have contributed to past pandemics. Read more ›

Dozens of Alaska's rivers and streams are turning orange. The staining could be the result of minerals exposed by thawing permafrost and climate change, finds a new study. Read more ›

On the heels of a shortage of nirsevimab for infant respiratory syncytial virus (RSV) lower respiratory tract infection (LRTI) prevention, a new tool may help identify newborns at highest risk for developing serious RSV LRTI, according to new research. Read more ›

Currently available flu medications only target the virus after it has already established an infection, but what if a drug could prevent infection in the first place? Now, scientists have designed drug-like molecules to do just that, by thwarting the first stage of influenza infection. Read more ›

Researchers have been focusing on non-thermal atmospheric-pressure plasma as a treatment method that can shorten recovery times, such as for tendon repair. Using a helium plasma jet, they demonstrated that irradiation of ruptured Achilles tendons showed accelerated regeneration and increased strength at an earlier stage than if the injury site was not irradiated.

University of Copenhagen astrophysicists help explain a mysterious phenomenon, whereby stars suddenly vanish from the night sky. Their study of an unusual binary star system has resulted in convincing evidence that massive stars can completely collapse and become black holes without a supernova explosion. Read more ›

Researchers have for the first time been able to pin down a prehistoric settlement of early farmers in northern Greece dating back more than 7,000 years to the year. For this they combined annual growth ring measurements on wooden building elements with the sudden spike of cosmogenic radiocarbon in 5259 BC. This provides a reliable chronological reference point for many other archaeological sites in Southeast Europe. Read more ›

Researchers have used a unique microscopic technique to examine the dynamics of pollen tubes in the Arabidopsis plant. They were able to observe the mechanism of one-to-one pollen tube guidance, a process that ensures successful pollination of plants. This process is influenced by multi-step repelling and attracting signals. The results are important for the cultivation of crops, especially under unfavorable environmental conditions. Read more ›

Researchers show that nocturnal heat significantly increases the risk of stroke. The findings can contribute to the development of preventive measures: With them, the population can better protect themselves against the risks of climate change with increasingly frequent hot nights. In addition, knowledge of the consequences of hot nights can improve patient care. Read more ›

Researchers have developed a type of chocolate that is more sustainable and nutritious than conventional varieties. Cocoa-fruit chocolate uses cocoa fruit jelly as a replacement for powdered sugar, reducing the sugar content and increasing the product's nutritional value. This new chocolate recipe also has the potential to diversify the income sources of small farmers. Read more ›

Current methods to model or correct mutations in live cells are inefficient, especially when multiplexing -- installing multiple point mutations simultaneously across the genome. Researchers have developed new, efficient genome editing tools called multiplexed orthogonal base editors (MOBEs) to install multiple point mutations at once. Read more ›

Although periodontitis is an extremely prevalent disorder, it is challenging to conduct detailed and comprehensive analyses of its progression at the cellular level. Recently, researchers developed an improved periodontitis mouse model that simplifies the collection and analysis of multiple periodontal tissue types. Using this model, they clarified the role of an important signaling pathway in the inflammatory response of periodontal tissue, paving the way for better diagnostic and therapeutic strategies...

Scientists discover 'zoned development' in dinosaur skin, with zones of reptile-style scales and zones of bird-like skin with feathers. A new dinosaur skin fossil has been found to be composed of silica -- the same as glass. Read more ›

Natural materials like bone, bird feathers and wood have an intelligent approach to physical stress distribution, despite their irregular architectures. However, the relationship between stress modulation and their structures has remained elusive. A new study that integrates machine learning, optimization, 3D printing and stress experiments allowed engineers to gain insight into these natural wonders by developing a material that replicates the functionalities of human bone for orthopedic femur restoration.

Two new studies detail the changes seen at the single-cell level in pig organs and recipient human bodies before, during, and just after the xenotransplantation surgeries in the decedents. Read more ›

Sudden, severe dry spells known as flash droughts are rising in intensity around the world, with a notable exception in mountainous Central Asia, where flash drought extent is shrinking, according to new research. Heat and changes to precipitation patterns caused by a warming climate are driving these trends, the study found. Read more ›
