A new coating for lithium-ion batteries (LIBs), developed by scientists at UNIST promises extended driving for future electric vehicles (EVs). The coating, described in a paper published in the journal Nature Energy, when applied to LIBs is shown to have improved cycling stability even after being charged and discharged more than 500 times. As a result, the development of EV batteries that can drive longer distances with a single battery charge has gained considerable momentum. Distinguished Professor Jaephil Cho and his research team in the School of Energy and Chemical Engineering at UNIST unveiled ...

Binge drinking in adolescence is associated with changes in the volume of the cerebellum in young adulthood, a new study from the University of Eastern Finland and Kuopio University Hospital shows. Earlier studies have shown that excessive, long-term alcohol consumption causes damage to the cerebellum in adults, but there is very little data on the effects of adolescent drinking on the cerebellum. The findings were published in Alcohol. The study included 58 young adults aged 21 to 28 years, whose alcohol consumption had been monitored for the previous ten years. Of the participants, 33 had been heavy drinkers since adolescence, while 25 were light drinkers, consuming little or no alcohol at all. All of them were highly functional and had normal ...

An international research collaboration has used an omnidirectional camera attached to humpback whale to reveal how these creatures rest underwater.

The research group consisted of Assistant Professor Takashi Iwata of Kobe University's Graduate School of Maritime Sciences, Researcher Martin Biuw of the Norwegian Institute of Marine Research, Assistant Professor Kagari Aoki and Professor Katsufumi Sato of the Atmosphere and Ocean Research Institute, the University of Tokyo, and Professor Patrick Miller of the University of St. Andrews. These research results ...

A growing number of studies show that the environmental factors and lifestyle habits of pregnant women play an important role in the health of their child. But how about the semen quality of young men? Researchers at the University of Geneva (UNIGE), Switzerland, showed two years ago that only 38% of Swiss men had semne parameters above the thresholds set by the World Health Organisation (WHO) for fertile men. Epidemiologists from the Institut de recherche en santé, environnement et travail (IRSET, Rennes, France), in collaboration with the UNIGE team analyzed the potential impact of endocrine disruptors on semen quality of men whose mothers were working at the early ...

For the first time researchers from Hebrew University of Jerusalem, Radboudumc, Maastricht UMC+ and international colleagues have gained insight into the "hidden genetic defects" of the general European population. This is important because these defects, if inherited from both father and mother, can lead to all kinds of illnesses in their children. Research in the Dutch and Estonian population shows that every person has two to four such hidden genetic defects. In 1 in 100 couples, this leads to a situation with an increased risk of a genetic disease for future children. In the case of consanguinity, even 20 percent of the couples appear to be at high risk. This research is published in The American Journal of Human Genetics and Genetics in Medicine. The genes of a every ...

Aspergillus fumigatus kills as many people as malaria and tuberculosis, but is less known. It is found "everywhere", for example in the soil or in our compost, but is not normally dangerous to healthy people. Those who die from it often have a poor immune system or are hospitalized for lung infections, such as covid-19. Aspergillus also constitutes an increasing problem in agriculture, because the fungus causes deadly infections in both plants and animals. In the same way that many bacteria are resistant to antibiotics, also this fungus is now becoming more and more resistant to the limited repertoire of treatments. It is therefore important to find new ways to fight fungal ...

March 19, 2021, Bristol, UK - A new peer-reviewed study published in the journal Toxicological Research & Application shows acute exposure of a 3D human bronchial tissue model to e-cigarette aerosol has minimal impact on gene expression compared to smoke from combustible cigarettes. The research involved sub-cytotoxic exposure to cells in a 3D human bronchial model (MucilAirTM) to nicotine-containing vape aerosol, combustible cigarette smoke and fresh air control under strict laboratory conditions. The highly sensitive Toxicity Testing in the Twenty-First Century (TT21C)-based technique allows researchers to gain a ...

Approximately 8 out of every 10 health professionals in Spain are willing to be vaccinated against COVID-19, according to a study led by researchers from the Universitat Oberta de Catalunya (UOC). Published in the open-access journal Vaccines, the study assessed for the first time this population segment's willingness to be vaccinated against SARS-CoV-2 and concluded that the level of acceptance is higher among physicians than among nursing staff. Among the reasons given by health personnel for not wanting to be immunized, fears about the vaccines' safety and the potential side effects stood out. Although vaccination is considered to the most effective method for preventing and eradicating viral infections and stopping ...

The risk of being bullied at work is twice as high if you were born abroad. And if you come from a culture that is culturally dissimilar to Sweden's, the risk is even higher. These are the results of a Swedish study from Linköping University that was recently published in The International Journal of Human Resource Management. Employers in Sweden have a duty to ensure that the workplace is safe, with a healthy atmosphere. Despite this, some employees are treated poorly, excluded and ignored. When such treatment has continued for a longer period, it is defined as bullying. Researchers at Linköping University wanted to see if people born abroad run a greater risk of being bullied at work. "Our results show an increased risk of bullying ...

The headquarter of a eukaryotic cell is the nucleus, and most of the cell's information and instructions are stored there in the form of DNA (Deoxyribonucleic acid). The DNA, which is twisted, rolled and bundled two-meter-long chain, together with protein molecules, makes up the chromatin fiber that lays inside the nucleus. For years, scientists were curious how these components are organized. How is it possible that proteins necessary in biochemical reactions move efficiently within the nucleus full of DNA? Recent studies have finally solved the mystery. Findings describing it in detail were published in the Journal of Physical Chemistry Letters on December 21st, 2020. Molecules ...

Solar energy is a clean, renewable source of electricity that could potentially play a significant part in fulfilling the world's energy requirements, but there are still some challenges to fully capitalizing on this potential. Researchers looked into some of the issues that hamper the uptake of solar energy and proposed different policies to encourage the use of this technology. Installing solar panels to offset energy costs and reduce the environmental impact of their homes has been gaining popularity with homeowners in recent years. On a global scale, an increasing number of countries are similarly encouraging the installation of solar photovoltaics ...

CHAMPAIGN, Ill. -- A camera-trap study in the Mendocino National Forest in Northern California reveals that black bears are adept at finding and stealing the remains of adult deer killed by pumas. This "kleptoparasitism" by bears, as scientists call it, reduces the calories pumas consume in seasons when the bears are most active. Perhaps in response to this shortage, the pumas hunt more often and eat more small game when the bears are not in hibernation. The findings are published in the journal Basic and Applied Ecology. Pumas, also known as mountain lions or cougars, are apex ...

Due to their tissue-like mechanical properties, hydrogels are being increasingly used for biomedical applications; a well-known example are soft contact lenses. These gel-like polymers consist of 90 percent water, are elastic and particularly biocompatible. Hydrogels that are also electrically conductive allow additional fields of application, for example in the transmission of electrical signals in the body or as sensors. An interdisciplinary research team of the Research Training Group (RTG) 2154 "Materials for Brain" at Kiel University (CAU) has now developed a method to produce hydrogels with an excellent level of electrical conductivity. What makes this method special is that the mechanical properties of ...

How did life begin on Earth and could it exist elsewhere? Researchers at Simon Fraser University have isolated a genetic clue--an enzyme known as an RNA polymerase--that provides new insights about the origins of life. The research is published today in the journal Science. Researchers in SFU molecular biology and biochemistry professor Peter Unrau's laboratory are working to advance the RNA World Hypothesis in answer to fundamental questions on life's beginnings. The hypothesis suggests that life on our planet began with self-replicating ribonucleic acid (RNA) molecules, capable of not only carrying genetic information but also driving chemical reactions essential for life, prior to the evolution ...

In the future, droughts could be even more severe than those that struck parts of Germany in 2018. An analysis of climate data from the last millennium shows that several factors have to coincide to produce a megadrought: not only rising temperatures, but also the amount of solar radiation, as well as certain meteorological and ocean-circulation conditions in the North Atlantic, like those expected to arise in the future. A group of researchers led by the Alfred Wegener Institute have just released their findings in the journal Communications Earth & Environment. Despite the precipitation this winter, which in ...

Large areas of forests regrowing in the Amazon to help reduce carbon dioxide in the atmosphere, are being limited by climate and human activity. The forests, which naturally regrow on land previously deforested for agriculture and now abandoned, are developing at different speeds. Researchers at the University of Bristol have found a link between slower tree-growth and land previously scorched by fire. The findings were published today [date] in Nature Communications, and suggest a need for a better protection of these forests if they are to help mitigate the effects of climate change. Global forests are expected to contribute a quarter of pledged mitigation under the ...

OSAKA, Japan. If you were given the option to eat a delicious meal by yourself, or share that meal with your loved ones, you would need as very good excuse ready if you chose the former. Turns out, fish share a similar inclination to look after each other. For the first time ever, a research group led by researcher Shun Satoh and Masanori Kohda, professor of the Graduate School of Science, Osaka City University, have shown these altruistic tendencies in fish through a series of prosocial choice tasks (PCT) where they gave male convict cichlid fish two choices: the antisocial option of receiving food for themselves alone and the prosocial option of receiving food for themselves and their partner. "As a result, it can be said that the convict cichlid ...

In a recent study led by the University of Bristol, scientists have shown how to simultaneously harness multiple forms of regulation in living cells to strictly control gene expression and open new avenues for improved biotechnologies. Engineered microbes are increasingly being used to enable the sustainable and clean production of chemicals, medicines and much more. To make this possible, bioengineers must control when specific sets of genes are turned on and off to allow for careful regulation of the biochemical processes involved. Their findings are reported today in the journal Nature Communications. Veronica Greco, lead author ...

Scientists have discovered in more detail than ever before how the human body's immune system reacts to malaria and sickle cell disease. The researchers from the universities of Aberdeen, Edinburgh, Exeter and Imperial College, London have published their findings in Nature Communications. Every year there are ~200 million cases of malaria, which causes ~400,000 deaths. As it causes resistance against malaria, the sickle cell disease mutation has spread widely, especially in people from Africa. But if a child inherits a double dose of the gene - from both mother and father - they will develop ...

Researchers at the Paul Scherrer Institute PSI have for the first time observed photochemical processes inside the smallest particles in the air. In doing so, they discovered that additional oxygen radicals that can be harmful to human health are formed in these aerosols under everyday conditions. They report on their results today in the journal Nature Communications. It is well known that airborne particulate matter can pose a danger to human health. The particles, with a maximum diameter of ten micrometres, can penetrate deep into lung tissue and settle ...

Researchers looking at miniscule levels of plutonium pollution in our soils have made a breakthrough which could help inform future 'clean up' operations on land around nuclear power plants, saving time and money. Publishing in the journal Nature Communications, researchers show how they have measured the previously 'unmeasurable' and taken a step forward in differentiating between local and global sources of plutonium pollution in the soil. By identifying the isotopic 'fingerprint' of trace-level quantities of plutonium in the soil which matched the ...

A study of Japanese university students and recent graduates has revealed that writing on physical paper can lead to more brain activity when remembering the information an hour later. Researchers say that the unique, complex, spatial and tactile information associated with writing by hand on physical paper is likely what leads to improved memory. "Actually, paper is more advanced and useful compared to electronic documents because paper contains more one-of-a-kind information for stronger memory recall," said Professor Kuniyoshi L. Sakai, a neuroscientist at the University of Tokyo and corresponding author of the research recently published in Frontiers in Behavioral Neuroscience. The research was completed with collaborators from the NTT Data Institute of Management Consulting. Contrary ...
