University of Calgary study shows BPA exposure below regulatory levels can impact development of the brain's sleep centre, effecting behavior. The researchers found striking changes to the brain region responsible for driving circadian rhythms. The suprachiasmatic nucleus, located in the hypothalamus, failed to develop properly. This change can have implications for sleep, activity levels, and other behaviors. Bisphenol A, also known as BPA is commonly found in plastics, and canned food linings.

Machine learning, when used in climate science builds an actual understanding of the climate system. This means we can trust machine learning and further its applications in climate science, say the authors.

The University of Ottawa's Positive Energy program released new survey results showing that a large segment of the Canadian public does not trust the courts to settle disputes over energy projects or climate policy. The survey was conducted by Positive Energy's official pollster, Nanos Research.

Using a Fitbit and a spy mic, scientists have discovered new insight into the behavior of the elusive Canada lynx. A new study by researchers from McGill University, University of Alberta, and Trent University provides a first look at how miniaturized technology can open the door to remote wildlife monitoring.

The so-called Plexin-A1 gene seems to play a more extensive role in brain development than previously assumed. This is shown by a current study led by the University of Bonn (Germany) with more than 60 international partners. The gene is also interesting for another reason: Its mutations are inherited either dominantly or recessively, depending on which part of the gene is affected. The results of the study are published in the journal "Genetics in Medicine".

The study recently published in Biomedical Optics Express and authored by members of the consortium reports on several study cases and clinical tests conducted to validate the accuracy and high quality of measurements achieved by the LUCA device.

Energy communities will play a key role in building the more decentralized, less carbon intensive, and fairer energy systems of the future. Such communities enable local prosumers (consumers with own generation and storage) to generate, store and trade energy with each other -- using locally owned assets, such as wind turbines, rooftop solar panels and batteries.

Researchers use the abundant chemical element manganese as active material.

YouTube is a treasure trove of virtual reality fails: users tripping, colliding into walls and smacking inanimate and animate objects. By investigating these "VR Fails" on YouTube, researchers at the University of Copenhagen have sought to learn more about when and why things go sideways for users and how to improve VR design and experiences so as to avoid accidents.

Researchers from Trinity College Dublin have developed a novel set of tools for designing vitamin D clinical trials that capture large seasonal and population-wide differences in vitamin D status, typically seen in individuals. Their study provides a framework for clinical trials to establish whether vitamin D supplementation is effective against a given disease.

In many species including humans, the cells responsible for reproduction, the germ cells, are often highly interconnected and share their cytoplasm. In the hermaphrodite nematode Caenorhabditis elegans, up to 500 germ cells are connected to each other in the gonad, the tissue that produces eggs and sperm. These cells are arranged around a central cytoplasmic 'corridor' and exchange cytoplasmic material fostering cell growth, and ultimately produce oocytes ready to be fertilized.

The National Institute of Polar Research publishes Polar Science, a peer-reviewed quarterly journal dealing with polar science in collaboration with the Elsevier B. V.. The most recent issue was a special issue entitled "Arctic Challenge for Sustainability Project (ArCS)," which featured the former national (nationwide) Arctic research project in Japan. The full text of this issue is freely accessible worldwide for a limited time until Sept. 10, 2021.

The intriguing chemistry and biology of sulfur?containing natural products from marine microorganisms (1987-2020)https://doi.org/10.1007/s42995-021-00101-2Announcing a new publication for Marine Life Science & Technology journal. In this review article the authors Yang Hai, Mei?Yan Wei, Chang?Yun Wang, Yu?Cheng Gu and Chang?Lun Shao from Ocean University of China, Qingdao, China and Syngenta Jealott's Hill International Research Centre, Berkshire, UK consider the chemistry and biology of sulfur?containing natural products from marine microorganisms.

Skoltech researchers used the resources of the university's Zhores supercomputer to study a new method of generating gamma-ray combs for nuclear and X-ray photonics and spectroscopy of new materials.

In an article published in JACC, CNIC scientists report a method for improved ranking of cardiovascular risk in individuals without diabetes

New research has found that adolescents with higher levels of an omega-3 fatty acid in their blood were less likely to develop psychotic disorder in early adulthood, suggesting that it may have a potential preventative effect of reducing the risk of psychosis.

The study demonstrates for the first time that a problem with angiogenesis (the mechanism by which new blood vessels are produced) causes the destruction of capillaries and, therefore, a decrease in the supply of nutrients and oxygen to the brain.

RNA sequencing is a powerful technology for studying cells and diseases. Scientists from the research group of Christoph Bock, principal investigator at the CeMM Research Center for Molecular Medicine of the Austrian Academy of Sciences and professor at the Medical University of Vienna, developed a new method for sequencing huge numbers of single cells in an efficient manner. The study has now been published in Nature Methods.

Women carrying human papillomavirus (HPV) run an elevated risk of preterm birth, a University of Gothenburg study shows. A connection can thus be seen between the virus itself and the risk for preterm birth that previously has been observed in pregnant women who have undergone treatment for abnormal cell changes due to HPV.

In the deep waters that underlie the productive zones of the ocean, there is a constant rain of organic material called 'marine snow.' Marine snow behaves similarly to real snow: large flakes are rare and fall quickly while abundant smaller flakes take their time. Scientists have now discovered that precisely those features explain why small particles play an important role for the nutrient balance of the oceans. These findings have been published in Nature Communications.
