Young clownfish living closest to shore are dying faster than those further offshore because they are being exposed to artificial lighting, says an international research team.
Working on the reefs around Moorea in French Polynesia, scientists from France, the United Kingdom, Chile and Australia found that nearshore juvenile clownfish living in anemones under lights had higher mortality than juveniles in anemones not exposed to artificial light.
New Curtin research has shown how a readily available, cheap and safe-to-use product found in the medicine cabinet of most homes could be the key to better ecological restoration practices with major benefits for the environment and agriculture.
The study revealed that aspirin, which naturally occurs in the bark of the willow tree and other plants, can improve the survival of grass species important for ecological restoration and sustainable pasture when applied in a seed coating.
Scientists have leapt over the emerging problem of publication bias within genetic research by performing a meta-analysis of publicly available databases of 'transcriptomes', or the full range of messenger RNA molecules produced by an organism. Researchers from Hiroshima University applied the technique to their own field--the study of the genes that are activated when an organism experiences low-oxygen conditions--but it should also be applicable in any other fields that make use of the transcriptome, providing a powerful weapon against the threat posed by publication bias.
A research collaboration based in Kumamoto University, Japan has revealed the DNA methylation status of gene transcriptional regulatory regions in the frontal lobes of patients with bipolar disorder (BD). The regions with altered DNA methylation status were significantly enriched in genomic regions which were reported to be genetically related to BD. These findings are expected to advance the understanding of the pathogenesis of BD and the development of therapeutic drugs targeting epigenetic conditions.
RUDN University chemist with his colleagues from Portugal has developed two types of coating based on new coordination polymers with silver. Both compounds were successfully tested against four common pathogens. The results are published in ACS Publications (ACS Appl. Mater. Interfaces).
Tokyo, Japan - Incoming sensory information can affect the brain's structure, which may in turn affect the body's motor output. However, the specifics of this process are not always well understood. In a recent study published in Scientific Reports, researchers from Tokyo Medical and Dental University (TMDU) found that when young rats were fed a diet of either soft or regular food, these different sensory inputs led to differences in muscle control and electrical activity of the jaw when a specific chewing-related brain region was stimulated.
Indigenous Māori people may have set eyes on Antarctic waters and perhaps the continent as early as the 7th century, new research published in the peer-reviewed Journal of the Royal Society of New Zealand shows.
Over the last 200 years, narratives about the Antarctic have been of those carried out by predominantly European male explorers.
RUDN University professor and her colleagues from France proved that higher intake of magnesium and vitamin B6 helps to cope with the consequences of magnesium deficiency during pregnancy and in hormone-related conditions in women. Within four weeks, the painful symptoms become less severe, the quality of life improves, and the risks of miscarriage are reduced. The results of the study are published in Scientific Reports.
The research team led by Prof. GUO Guangcan from the University of Science and Technology of China (USTC) of the Chinese Academy of Sciences (CAS), together with Prof. Adam Gali from Wigner Research Centre for Physics, realized robust coherent control of solid-state spin qubits using anti-Strokes (AS) excitation, broadening the boundary of quantum information processing and quantum sensing. This study was published in Nature Communications.
A research team led by Professor Jianping Huang from Lanzhou University has launched a Global Prediction System for COVID-19 pandemic. Their recent work explored the periodicity and mutability in the evolutionary history of the COVID-19 pandemic and investigated the principle mechanisms behind them. They attributed the periodic oscillations of COVID-19 daily cases to seasonal modulations and reporting bias, and identified the unrestricted mass gatherings as the main culprit of the COVID-19 disaster.
Scientists from the lab of Franz Klein from the Department of Chromosome Biology at the Max Perutz Labs, a joint venture of the University of Vienna and the Medical University of Vienna, have now discovered that cells sometimes liberate DNA fragments at sites of paired, or double, DSBs. Whilst this presents an obvious risk of germline mutations as a consequence of erroneous repair or of integration of fragments from elsewhere at break sites, it may also be a source of evolutionary diversity. The study is published as a research article in Nature.
Language is one of our species' most important skills, as it has enabled us to occupy nearly every corner of the planet. Among other things, language allows indigenous societies to use the biodiversity that surrounds them as a "living pharmacy" and to describe the medicinal properties of plants. Linguists estimate that there are nearly 7,400 languages in the world today.
Researchers at the University of Geneva (UNIGE) demonstrate that innovative projects spearheaded by United Nations (UN) country offices are remodeling the institution and expanding its role. Digital initiatives, particularly those scaled through headquarters, were shown to have the strongest impact, changing ways of working, embedding new skills, and restructuring teams across the UN. These findings, published in the Journal of Management Studies, highlight that fostering even single innovative projects could lead to fundamental transformations in the UN.
Scientists from the University of Melbourne and University of Queensland have revealed the mystery behind the unique reproductive parts of the much-loved echidna.
In the paper, "The Unique Penile Morphology of the Short-Beaked Echidna, Tachyglossus aculeatus", the team detail how the male monotreme's testes never descend, have no scrotum, and when not in use, their penis is stored internally.
Led by Professor Andreas Hartmann, from the University of Freiburg (Germany), the researchers analyzed the presence of several pollutants in water from many karst aquifers of Europe, North Africa, and the Middle East, relating fast infiltration processes to an increased concentration of these substances. The findings of this research are published in the scientific journal Proceedings of the National Academy of Sciences (PNAS).
