During the era of commercial whaling, fin whales were hunted so intensively that only a small percentage of the population in the Southern Hemisphere survived, and even today, marine biologists know little about the life of the world's second-largest whale.

Researchers designed a alloy comprised of cheap and earth-abundant metal element with better efficiency than traditional platinum-based anode and time endurance to boost the commercialization of hydrogen energy.

Metal-organic framework compounds (MOFs) are widely used in gas storage, material separation, sensor technology or catalysis. A team led by Prof. Dr. Stefan Kaskel, TU Dresden, has now investigated a special class of these MOFs at the MX beamlines of BESSY II. These are "switchable" MOFs that can react to external stimuli. Their analysis shows how the behaviour of the material is related to transitions between ordered and disordered phases. The results have now been published in Nature Chemistry.

Researchers have combined two or three types of nanoparticles to produce new materials with structures known as superlattices. In some instances, the structures display fundamental new properties such as superfluorescence. The researchers' discovery is reported in the journal Nature and featured on the current issue's cover.

The countries around the Baltic Sea do not respect their binding international agreement to reduce agricultural pollution of the marine environment. Despite farming activities being the single most important source of nutrient pollution to the Baltic Sea.

Engineering researchers from Aarhus University have developed electronic support stockings and tested them on 16 bed-ridden Covid-19 patients at Copenhagen University Hospitals, Bispebjerg and Herlev. The experiments show that the stockings counteract a significant loss of muscle mass.

The basis for this new take on the classification was laid in 1985, when John Long attributed a fossil tooth plate to a new species, Edaphodon eyrensis. The species was named after Lake Eyre, near which the tooth was found in 1978.

Scientists from the University of Sussex have recorded blood oxygen levels in the hippocampus and provided experimental proof for why the area, commonly referred to as 'the brain's memory centre', is vulnerable to damage and degeneration, a precursor to Alzheimer's disease.

World Vape Day: BAT publishes review highlighting 10 years of scientific evidence on vaping

Colchicine could be considered as a treatment for non-hospitalized patients diagnosed with COVID-19 by PCR test and at risk of complications.

This study aimed to investigate self-reported symptoms of disease flares among patients with rheumatoid arthritis or systemic lupus erythematosus during the COVID-19 pandemic.

A deeper understanding of how the environment impacts quantum behaviour is bringing quantum devices one step closer to widespread adoption.

Developing a novel and convenient method to prepare dual emission nitrogen-doped carbon dots, which can be used as a ratiometric fluorescent probe for detecting dopamine based on the variation of the ratio (I595nm/I435nm).

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?
