Research on manufacturing battery cells is gaining momentum - and there is a strong need, considering the future demand for energy storage: For the year 2030, global production of rechargeable batteries will double from today's 750 gigawatt hours (GWh) per year to 1,500 GWh. A recently published review article in the magazine "Nature Energy" on cell production of various battery types suggests that the currently established lithium-ion batteries (LIB) dominate the market of rechargeable high-energy batteries in the coming years. Alternative battery technologies, ...

Large parts of today's Sahara Desert were green thousands of years ago. Prehistoric engravings of giraffes and crocodiles testify to this, as does a stone-age cave painting in the desert that even shows swimming humans. However, these illustrations only provide a rough picture of the living conditions. Recently, more detailed insights have been gained from sediment cores extracted from the Mediterranean Sea off the coast of Libya. An international research team examined these cores and discovered that the layers of the seafloor tell the story of major environmental changes in North Africa over ...

The biological process of photosynthesis is found at the beginning of nearly all food chains. It produces oxygen to breathe and provides the energetic foundation for using biotechnological processes to synthesize biofuels and chemical feedstock. Therefore, researchers are particularly interested in rapidly growing cyanobacteria. These organisms use light as an energy source and can carry out photosynthesis, similar to plants. However, the required photosynthetic protein complexes bind many nutrients. Vanessa Krauspe and Prof. Dr. Wolfgang Hess from the working group for Genetics & Experimental Bioinformatics of the Faculty of Biology of ...

Who hasn't at some point been chewing on an almond and tasted an unpleasant and unexpected aftertaste that has nothing to do with the taste we are used to from one of the most consumed nuts in the world? The culprit has a name: amygdalin, a diglucoside that, when in contact with enzymes present in saliva, breaks down into glucose, benzaldehyde (the cause of the bitter taste) and hydrogen cyanide. To reduce this unpleasant 'surprise', the Farming Systems Engineering (AGR-128) and Food Technology (AGR-193) research groups at the University of Cordoba's School of Agricultural and Forestry Engineering, ...

SORLA is a protein trafficking receptor that has been mainly studied in neurons, but it also plays a role in cancer cells. Professor Johanna Ivaska's research group at Turku Bioscience observed that SORLA functionally contributes to the most reported therapy-resistant mechanism by which the cell-surface receptor HER3 counteracts HER2 targeting therapy in HER2-positive cancers. Removing SORLA from cancer cells sensitized anti-HER2 resistant breast cancer brain metastasis to targeted therapy. HER2 protein is a strong driver of tumor growth. HER2 amplification occurs ...

High-intensity tropical cyclones have been moving closer to coasts over the past 40 years, potentially causing more destruction than before. The trend of tropical cyclones - commonly known as hurricanes or typhoons - increasingly moving towards coasts over the past 40 years appears to be driven by a westward shift in their tracks, say the study's authors from Imperial College London. While the underlying mechanisms are not clear, the team say it could be connected to changes in tropical atmospheric patterns possibly caused by climate change. The research is published today in Science. Globally, 80 to 100 cyclones develop over tropical oceans each year, impacting regions in the Pacific, ...

New research by Mimi E. Lam (University of Bergen) just published in Humanities and Social Sciences Communications identifies and explores the impacts of salient viral or COVID-19 behavioural identities that are emerging. "These emergent COVID-19 behavioural identities are being hijacked by existing social and political identities to politicize the pandemic and heighten racism, discrimination, and conflict," says Lam. She continues: "the COVID-19 pandemic reminds us that we are not immune to each other. To unite in our fight against the pandemic, it is important to recognize the basic dignity of all and value the human diversity currently dividing us." "Only ...

Drawing on animal-foraging theory, a new model predicts psychological factors that may lead to panic buying during times of crisis. The model is largely supported by real-world data from the COVID-19 pandemic. Richard Bentall of the University of Sheffield, England, and colleagues presented these findings in the open-access journal PLOS ONE on January 27. In the early stages of the pandemic, consumers in several countries around the world engaged in "panic buying" of household items, causing temporary shortages of toilet rolls and other products. Such behavior is typical during times of crisis, but few studies have examined the psychology of crisis-driven over-purchasing. To better understand this phenomenon, Bentall and colleagues turned to animal-foraging ...

As one of the most experienced archaeologists studying California's Native Americans, Lynn Gamble(link is external) knew the Chumash Indians had been using shell beads as money for at least 800 years. But an exhaustive review(link is external) of some of the shell bead record led the UC Santa Barbara professor emerita of anthropology to an astonishing conclusion: The hunter-gatherers centered on the Southcentral Coast of Santa Barbara were using highly worked shells as currency as long as 2,000 years ago. "If the Chumash were using beads as money 2,000 years ago," Gamble said, "this changes our thinking of hunter-gatherers and sociopolitical and economic complexity. This may be the first example of the use of money anywhere in the ...

As part of standard patient protocol, doctors inform women of the risks of pregnancy. But there is one exception to this standard: stillbirth. University of Arkansas law professor Jill Wieber Lens argues that women have a right to know of the risk of stillbirth, and, consistent with the evolution of informed consent law, this right should be enforceable through a medical malpractice tort claim. Stillbirth, or pregnancy loss after 20 weeks but before birth, is not uncommon. Annually, 26,000 U.S. women give birth to a stillborn baby, or roughly one out every 160 pregnancies. The United States' stillbirth rate ...

COLLEGE PARK, Md.--The amount of methane released into the atmosphere as a result of coal mining is likely much higher than previously calculated, according to research presented at the annual meeting of the American Geophysical Union recently. The study estimates that methane emissions from coal mines are approximately 50 percent higher than previously estimated. The research was done by a team at the U.S. Department of Energy's Pacific Northwest National Laboratory, the U.S. Environmental Protection Agency and others. The higher estimate is due mainly to two factors: methane that continues to be emitted from thousands of abandoned mines and the higher methane content in coal seams that are ever deeper, according to chief ...

The Japanese now have their own reference genome thanks to researchers at Tohoku University who completed and released the first Japanese reference genome (JG1). Their study was published in the journal Nature Communications on January 11, 2021. "JG1 can aid with the clinical sequence analysis of Japanese individuals with rare diseases as it eliminates the genomic differences from the international reference genome," said Jun Takayama, co-author of the study. Back in 2003, the Human Genome Project, through a gargantuan global effort, cracked the code of life and mapped all the genes of the human genome. Since then, more accurate versions of the human reference genome have ...

The researchers of the Institute for Atmospheric and Earth system research at the University of Helsinki have investigated how atmospheric particles are formed in the Arctic. Until recent studies, the molecular processes of particle formation in the high Arctic remained a mystery. During their expeditions to the Arctic, the scientists collected measurements for 12 months in total. The results of the extensive research project were recently published in the Geophysical Research Letters journal. The researchers discovered that atmospheric vapors, particles, and cloud formation have clear differences within various Arctic environments. The study clarifies how Arctic warming and sea ice loss strengthens processes where different vapors are emitted to the atmosphere. The ...

The Covid-19 pandemic has made home offices, virtual meetings and remote learning the norm, and it is likely here to stay. But are people paying attention in online meetings? Are students paying attention in virtual classrooms? Researchers Jens Madsen and Lucas C. Parra from City College of New York, demonstrate how eye tracking can be used to measure the level of attention online using standard web cameras, without the need to transfer any data from peoples computers, thus preserving privacy. In a paper entitled "Synchronized eye movements predict test scores in online video education," published in the Proceedings of the National Academy of Sciences, they show that just ...

Scientists at Johannes Gutenberg University Mainz (JGU) and ETH Zurich have developed a process to produce commodity chemicals in a much less hazardous way than was previously possible. Such commodity chemicals represent the starting point for many mass-produced products in the chemical industry, such as plastics, dyes, and fertilizers, and are usually synthesized with the help of chlorine gas or bromine, both of which are extremely toxic and highly corrosive. In the current issue of Science, the researchers report that they have been able to utilize electrolysis, i.e., the application of an electric current, to obtain chemicals known as dichloro and dibromo compounds, which can then be used to synthesize ...

A new study has found that mobile apps can play a vital role in helping immigrants integrate into new cultures, as well as provide physical and mental health benefits. Researchers at Anglia Ruskin University (ARU) surveyed new migrants and refugees undertaking free beginners' language classes in Greece, often the first destination for people arriving into Europe from Africa and Asia, over a 10-month period. The findings, published in the journal Computers in Human Behavior, show that those using mobile apps aided by artificial intelligence (AI), such as language assistants, customised information sites, or health symptom trackers, experienced ...

New research has revealed how an invasion of the alien evergreen tree, Prosopis juliflora seriously diminishes water resources in the Afar Region of Ethiopia, consuming enough of this already scarce resource to irrigate cotton and sugarcane generating some US$ 320 million and US$ 470 million net benefits per year. A team of Ethiopian, South African and Swiss scientists, including lead author Dr Hailu Shiferaw, Dr Tena Alamirew, and Dr Gete Zeleke from the Water and Land Resource Centre of Addis Ababa University, Ethiopia, and Dr Sebinasi Dzikiti from Stellenbosch University, ...

Scientists have broadened our understanding of how 'weak' cells bond with their more mature cellular counterparts to boost the body's production of insulin, improving our knowledge of the processes leading to type 2 diabetes - a significant global health problem. Type 2 diabetes mellitus occurs when β-cells cannot release enough insulin - a tightly controlled process requiring hundreds of such cells clustered together to co-ordinate their response to signals from food, such as sugar, fat and gut hormones. An international research team - led by scientists at the University of ...

Engineers at Tufts University have created and demonstrated flexible thread-based sensors that can measure movement of the neck, providing data on the direction, angle of rotation and degree of displacement of the head. The discovery raises the potential for thin, inconspicuous tatoo-like patches that could, according to the Tufts team, measure athletic performance, monitor worker or driver fatigue, assist with physical therapy, enhance virtual reality games and systems, and improve computer generated imagery in cinematography. The technology, described today in Scientific Reports, adds to a growing number of thread-based ...

Researchers from the Hubrecht Institute mapped the recovery of the heart after a heart attack with great detail. They found that heart muscle cells - also called cardiomyocytes - play an important role in the intracellular communication after a heart attack. The researchers documented their findings in a database that is accessible for scientists around the world. This brings the research field a step closer to the development of therapies for improved recovery after heart injury. The results were published in Communications Biology on the 29th of January. In the Netherlands, an average of 95 people end up in the hospital each day ...

Efforts to understand when corals reproduce have been given a boost thanks to a new resource that gives scientists open access to more than forty years' worth of information about coral spawning. Led by researchers at Newcastle University, UK, and James Cook University, Australia, the Coral Spawning Database (CSD) for the first time collates vital information about the timing and geographical variation of coral spawning. This was a huge international effort that includes over 90 authors from 60 institutions in 20 countries. The data can be used by scientists and conservationists to better understand the environmental cues that influence when coral ...

(Singapore--16:45 p.m. SPT/3:45 EST January 29, 2021)--Two presentations from the ADAURA clinical trial advanced previous research that demonstrated improved disease-fee survival (DFS) outcomes for patients with surgically resected non-small cell lung cancer (NSCLC) receiving osimertinib. The data were reported today at the International Association for the Study of Lung Cancer's 2020 World Conference on Lung Cancer (WCLC) Singapore. Osimertinib is a third-generation, irreversible, central nervous system-active, epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitor. ADAURA is a randomized Phase III trial comparing adjuvant osimertinib with placebo in patients ...

Beyond the ski slopes, one of the most iconic symbols of the Alps are the alpine flowers. These plants are not only beautiful -- they are also used in liqueurs and medicines, and they form the foundation of the local food chains. But a recent study in Frontiers in Ecology and Evolution shows that, although plant diversity may initially increase with glacier retreat, many of these species may soon become endangered. "Our results indicate that plant diversity will ultimately decrease once the glaciers disappear -- and up to 22% of the species we analyzed may locally disappear or even go extinct once the glaciers are gone," says lead author Dr Gianalberto Losapio of Stanford University in the USA. "We show that 'not all species are equal before global warming' and that there are some species ...

Methane (CH4) is the second most important greenhouse gas after carbon dioxide (CO2). Its concentration in the atmosphere has increased more than twice since the preindustrial era due to enhanced emissions from human activities. While the global warming potential of CH4 is 86 times as large as that of CO2 over 20 years, it stays in the atmosphere for about 10 years, much shorter than more than centuries of CO2. It is therefore expected that emission controlling of CH4 can benefit for relatively short time period toward the Paris Agreement target to limit the global warming well below 2 degrees. A study by an international team, published ...

New research from the University of Sheffield has found being overweight is an additional burden on brain health and it may exacerbate Alzheimer's disease. The pioneering multimodal neuroimaging study revealed obesity may contribute toward neural tissue vulnerability, whilst maintaining a healthy weight in mild Alzheimer's disease dementia could help to preserve brain structure. The findings, published in The Journal of Alzheimer's Disease Reports, also highlight the impact being overweight in mid-life could have on brain health in older age. Lead author of the study, Professor Annalena Venneri from the University of Sheffield's Neuroscience Institute and NIHR Sheffield Biomedical Research Centre, ...
