Research team of Samara Polytech in cooperation with the crystallographic research group of Lomonosov Moscow State University studied non-racemic 4,5-dihydrofurans.

1. Development of a two-photon excitation light-sheet microscope which achieves low phototoxicity, an extended field of view, and high resolution for the observation of the growth of living organisms2. Applications of the microscope demonstrate long-term time-lapse observations for a three-day span of the embryonic development of medaka fish

The work was conducted under the auspices of the Russian Foundation for Basic Research and organizations-participants of the BRICS framework program in science, technology and innovation; the grant title is "Nanosized peptide-based biomaterials for photodynamic diagnostics of tumors".

An international archaeological study, led by researchers from the Culture and Socio-Ecological Dynamics (CaSEs) research group, has advanced in the understanding and preservation of archaeological sites and in improving their analysis, thanks to the application of pXRF (portable X-ray fluorescence analysis) to anthropogenic sediments in Africa. It is a rapid, inexpensive, non-invasive procedure, which enables generating an additional archaeological record from the anthropogenic deposit by analysing chemical elements, combined with geostatistics.

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.
