Narrating the basic knowledge of nanofibrous filters. The mechanical-dependent and electrostatic-dependent nanofibrous filters were summarized according to their mechanical adsorption and electrostatic adsorption to the nanoparticles, respectively, which will help to understand and design better performance nanofibrous filters.

The authors, Kirill Vasin and Mikhail Eremin, contribute to the theory of electronic and structural properties of FeCr2O4 ferrimagnet.

A Cornell University-developed technology provides beekeepers, consumers and farmers with an antidote for deadly pesticides, which kill wild bees and cause beekeepers to lose around a third of their hives every year on average.

Proton transfer is an essential process for energy conversion in biological systems, but the transfer mechanism is little understood. Now, in a new study, a team of researchers from Japan has investigated the nature of proton transport for various concentrations of a proton-donating group in thin film polymers mimicking a biomaterial, providing important insights about the transport pathways and opening doors to biological technology involving proton conduction and eco-friendly fuel cells.

University of Montana researchers recently published a new study in the Journal of Wildlife Management analyzing why landowners do or don't secure attractants in bear country. The results suggest that collective or socially motivated factors may be a missing and important piece of the puzzle for encouraging voluntary steps to secure attractants and improve wildlife-human coexistence. The researchers also offer suggestions for how wildlife managers might help increase these behaviors through improved messaging and outreach.

While DNA is often idealised as the "molecule of life", it is also a highly sophisticated polymer that can be used for next-generation materials. Now, a collaboration of scientists from the Universities of Edinburgh, San Diego and Vienna have started to harness these properties to craft "topologically tunable" DNA-based complex fluids and soft materials with potential applications in drug delivery and tissue regeneration as published in Science Advances.

A look at Japan's mimamoru approach suggests that adults' non-intervention in kids' fights allows children to nurture social and interpersonal skills on their own. Is it worth a try in other countries?

The microscopic algae that live inside and provide nutrients to their reef-building coral hosts may be evolving in tandem with the corals they inhabit. A new study by Penn State biologists reveals that genetic differences within a species of these microalgal symbionts correspond to the coral species they inhabit, a discovery that could have implications for the conservation of these endangered corals.

This study aimed to assess the prognostic value of cTnI in COVID-19 patients.

Scientists from Japan, Europe and the USA have described a pathway leading to the accelerated flowering of plants in low-nitrogen soils. These findings could eventually lead to increases in agricultural production.

Australian scientists have found what could prove to be a new and effective way to treat a particularly aggressive blood cancer in children.

Researchers at the Department of Robotics Engineering at South Korea's Daegu Gyeongbuk Institute of Science and Technology (DGIST) have developed and tested a new type of human-like mechanical hand that combines the benefits of existing robot hands while eliminating their weaknesses. They describe their new design in the journal Soft Robotics.

A genetic study of 840,000 people found that shifting sleep time earlier by just an hour decreases risk of major depression by 23%.

The new findings identify a potential contributor to microcephaly, a birth defect in which the head is underdeveloped and abnormally small.

A breast cancer therapy that requires just one shot of radiotherapy is as effective as traditional radiotherapy, and avoids potential damage to nearby organs.

In collaboration with Kanazawa University, researchers from Osaka City University used high-speed atomic force microscopy (HS-AFM) to visualize at the nanometer level the movement of individual particles within the parasitic bacterium Mycoplasma mobile. After confirming the outline on the surface of the cell structure in an immobilized state with previous data gathered from electron microscopy, the team succeeded in visualizing the real-time movements of the internal structure by scanning the outside of the cell with HS-AFM.

A new study exploits the characteristic epigenetic signatures of childhood tumors to detect, classify and monitor the disease. The scientists analyzed short fragments of tumor DNA that are circulating in the blood. These "liquid biopsy" analyses exploit the unique epigenetic landscape of bone tumors and do not depend on any genetic alterations, which are rare in childhood cancers. This approach promises to improve personalized diagnostics and, possibly, future therapies of childhood tumors.

Understanding every step in the life cycle of a virus is crucial for identifying potential targets for treatment. Now, scientists at the Institute of Science and Technology (IST) Austria were able to show how a virus from the retrovirus family - the same family as HIV - protects its genetic information and becomes infectious. Furthermore, they show an unexpected flexibility of the virus. This study is published in the journal Nature Communications.

A new study published in Nature Scientific Reports has found that Methylene Blue, a century old medicine, has the potential to be a highly effective, broad-spectrum UV irradiation protector that absorbs UVA and UVB, repairs ROS and UV irradiation induced DNA damages, and is safe for coral reefs. The study suggests that Methylene Blue could become an alternative sunscreen ingredient that supports the environment and protects human skin health.

The technology using DNA-based genealogy that solved a double murder in Linköping opens completely new possibilities in investigating serious crime. LiU researchers are now involved in spreading new knowledge about the technology, which brings hope to police forces and has aroused major international interest.
