What do pipes and anchors have to do with storing energy? More than you might think! A new IIASA-led study explored the potential of a lesser known, but promising sustainable energy storage system called Buoyancy Energy Storage. There is general consensus that renewable energy sources will play an important role in ensuring a healthier and more sustainable future for the planet and its people, and many countries are indeed already seeing such technologies displacing "dirty" fossil fuels in the power sector in an effort to lower emissions. The biggest problem with renewable energy sources, however, is that power supply is intermittent, meaning that the energy output at any given time does not necessarily meet the demand at that time. ...

Our homes and offices are only as solid as the ground beneath them. When that solid ground turns to liquid -- as sometimes happens during earthquakes -- it can topple buildings and bridges. This phenomenon is known as liquefaction, and it was a major feature of the 2011 earthquake in Christchurch, New Zealand, a magnitude 6.3 quake that killed 185 people and destroyed thousands of homes. An upside of the Christchurch quake was that it was one of the most well-documented in history. Because New Zealand is seismically active, the city was instrumented ...

Several eye clinics around Sweden are seeing a rise in eye damage related to the racket sport padel. In an article in the Journal of the Swedish Medical Association (Läkartidningen), eye researchers affiliated with the University of Gothenburg state that padel is a potential high-risk sport for eye injuries, and that wearing protective goggles is a good idea. Ball sports are often associated with an increased risk of eye injuries, and the risk seems to be even greater with padel, a sport that is now highly popular in Sweden (and should not be confused with the North American "paddle tennis"). "The ...

ITHACA, N.Y. - Coming soon to a lab tabletop near you: a method of magneto-thermal imaging that offers nanoscale and picosecond resolution previously available only in synchrotron facilities. This innovation in spatial and temporal resolution will give researchers extraordinary views into the magnetic properties of a range of materials, from metals to insulators, all from the comfort of their labs, potentially boosting the development of magnetic storage devices. "Magnetic X-ray microscopy is a relatively rare bird," said Greg Fuchs, associate professor of applied and engineering physics, who led the project. "The magnetic ...

A research collaboration based in Kumamoto University (Japan) has identified a novel lncRNA, Caren, that is abundantly expressed in cardiomyocytes. They showed that it enhances energy production by increasing the number of mitochondria in cardiomyocytes, and inhibits activation of the ATM protein, a key player in the DNA damage response pathway that accelerates heart failure severity. Caren RNA in cardiomyocytes is reduced by aging and high blood pressure (hypertension), which can lead to heart failure, and markedly reduced in the hearts of heart failure patients. The researchers believe that ...

Eating 2.5 grams of pure natural cocoa powder serves to improve visual acuity in healthy young adults and in daylight conditions, according to research by the Universidad Complutense de Madrid (UCM) and the ICTAN (Institute of Food and Nutrition Science and Technology) of the CSIC. The study, published in the Journal of Functional Foods, analyse the effects of two dietary polyphenols: cocoa flavanols and red berry anthocyanins. "Although this was the baseline hypothesis, we did not see any effect either on adaptation to darkness or on visual acuity measured in low light conditions (mesopic vision), either with cocoa or with berries," indicates María Cinta Puell Marín, researcher at the Optometry and Vision ...

Children who were exposed to higher levels of trace minerals manganese and selenium during their mothers' pregnancy had a lower risk of high blood pressure in childhood, according to a study led by researchers at the Johns Hopkins Bloomberg School of Public Health. The researchers analyzed the levels of toxic metals and trace minerals in blood samples drawn from nearly 1,200 women in the Boston area who gave birth between 2002 and 2013. They found that higher levels of selenium or manganese in the mothers' blood were associated with lower blood pressure readings in their children ...

A sensitive blood test being developed by a team of researchers at the University of Michigan Rogel Cancer Center shows promise for predicting whether patients with metastatic HPV-positive throat cancer will respond to treatment months earlier than standard imaging scans. That's according to a study, published in Oncotarget, validating the test in a small group of patients with metastatic human papillomavirus-related oropharyngeal squamous cell carcinoma -- a type of head and neck cancer that develops in the back of the mouth and in the throat. If the test can quickly determine that a treatment approach isn't ...

AMHERST, Mass. - As summer unfolds, more than 500 species of invasive plants will be taking root in fields, lawns, and gardens across the US. As plants continue to move north driven by climate change, the number of invasives will only increase. Unfortunately, inconsistent regulations that vary from state to state means that invasive plants have an edge on our attempts to control them. However, new research from the University of Massachusetts Amherst recently published in the Journal of Applied Ecology suggests that we already have an answer in hand - communication. "We know that invasive plants are causing both ecological and economic harm in the US," says Emily Fusco, one of the paper's lead authors and a postdoctoral research fellow in the department of environmental conservation ...

OAK BROOK, Ill. - Researchers have developed an artificial intelligence (AI)-based brain age prediction model to quantify deviations from a healthy brain-aging trajectory in patients with mild cognitive impairment, according to a study published in Radiology: Artificial Intelligence. The model has the potential to aid in early detection of cognitive impairment at an individual level. Amnestic mild cognitive impairment (aMCI) is a transition phase from normal aging to Alzheimer's disease (AD). People with aMCI have memory deficits that are more ...

A year-long Australian population study has found that full time workers employed by organisations that fail to prioritise their employees' mental health have a threefold increased risk of being diagnosed with depression. And while working long hours is a risk factor for dying from cardiovascular disease or having a stroke, poor management practices pose a greater risk for depression, the researchers found. The University of South Australia study, published in the British Medical Journal today, is led by UniSA's Psychosocial Safety Climate Observatory, the world's first research platform exploring workplace psychological health and safety. Psychosocial safety climate (PSC) is the term used to describe management practices ...

In our future electrified world, the demand for battery storage is projected to be enormous, reaching to upwards of 2 to 10 terawatt-hours (TWh) of annual battery production by 2030, from less than 0.5 TWh today. However, concerns are growing as to whether key raw materials will be adequate to meet this future demand. The lithium-ion battery - the dominant technology for the foreseeable future - has a component made of cobalt and nickel, and those two metals face severe supply constraints on the global market. Now, after several years of research led by Lawrence Berkeley National Laboratory (Berkeley Lab), scientists have made significant progress in developing battery cathodes using ...

Tokyo, Japan - Stem cell therapy is at the cutting edge of regenerative medicine, but until now researchers and clinicians have had to painstakingly evaluate stem cell quality by looking at each cell individually under a microscope. Now, researchers from Japan have found a way to speed up this process, using the power of artificial intelligence (AI). In a study published in February in Stem Cells, researchers from Tokyo Medical and Dental University (TMDU) reported that their AI system, called DeepACT, can identify healthy, productive skin stem cells with the same accuracy that a human can. Stem cells are able to develop into several different kinds of mature ...

A team of researchers developed a biomimetic mineralization of calcium carbonate using a multifunctional peptide template that can self-supply mineral sources, which in this case is a supply of carbonate ions, the precursor of calcium carbonate, and following the mechanism of biosynthesis of hard tissues by living organisms, called biomineralization, the ability to form hydrogels, which is modeled after the reaction environment of living organisms. Previous studies on mineralization have discussed the formation mechanism of inorganic crystals synthesized on ...

Current American Heart Association, European Society of Cardiology, and UK National Health Service guidelines recommend a 5-yearly health checks for screening of individuals at high cardiovascular disease risk. These health checks include measurement of major risk factors, such as systolic blood pressure, cholesterol profile, blood glucose, and smoking status. If lifestyle interventions are unsuccessful in reducing risk factor levels, prevention guidelines recommend initiation of preventive medication therapies such as statins. However, current guidelines advice only using the latest ...

The results of the study were published in the journal "Neurology" on 19 May 2021 under the leadership of Professor Elena Enax-Krumova, holder of the endowed professorship of the German Social Accident Insurance (DGUV). Nerve injuries: frequent complication after occupational accidents Peripheral nerves refer to nerves that lie outside of the brain and spinal cord. They run throughout the entire body. These bundles of nerve fibres can be damaged in the event of blunt or sharp force trauma due to accidents, as well as during surgery. Injuries to the peripheral nerves are a frequent complication, particularly after occupational accidents. Patients often suffer from motor and sensory disorders in the affected area of the body. These can lead to persistent complaints and ...

Beware of those snack attacks. A new study in Appetite has confirmed the small luxuries, from sweets and chocolate to salty treats, have helped to lift our spirits - and kilojoule intake - during COVID-19 lockdowns. Researchers in England and Australia have gathered evidence about similar experiences in the UK and Victoria, Australia to warn about the effect of extended pandemic lockdowns on our eating behaviours. While time at home provides more time for healthy food preparation, intake of high-energy density foods (HED) has risen for some - presenting at-risk adults with the prospect of managing weight gain, the psychology researchers warn. "The ...

The response times of footballers is slowed down when part of the kit worn by both teams is of the same colour, a new study shows. The research from the University of York revealed that when players have any kit colour clash - either shirt or shorts - it takes them twice as long to find a fellow player on the pitch. Study authors are calling for a change in the laws of the game or for clearer guidance. Researchers used two experiments to investigate how kit variations affect the visual search for teammates. Their first experiment confirmed that a ...

Profs. Okujima and Uno at Ehime University, in collaboration with Prof. Kobayashi at Shinshu University, reported the selective synthesis, the molecular structure, optical properties and electronic structure of cyclo[9]pyrrole, a ring-expanded porphyrin consisting of directly connected pyrrole rings. Porphyrins, which are well-known natural porphyrin molecules, e.g. heme and chlorophyll, are attractive for use in practical materials because of the easy optimization of their optical and physical properties by conjugation expansion and functionalization. In 2002, Sessler reported the first synthesis of cyclo[n]pyrrole (n: ...

A new analysis of known exoplanets has revealed that Earth-like conditions on potentially habitable planets may be much rarer than previously thought. The work focuses on the conditions required for oxygen-based photosynthesis to develop on a planet, which would enable complex biospheres of the type found on Earth. The study is published today in Monthly Notices of the Royal Astronomical Society. The number of confirmed planets in our own Milky Way galaxy now numbers into the thousands. However planets that are both Earth-like and in the habitable zone - the region around a star where the temperature is just right for liquid water to exist on the surface - are much less common. At the moment, only a handful of such rocky and potentially habitable exoplanets ...

Research Associate Artyom Gusarov studied a vast array of erosion data to make a general takeaway that soil erosion and river sediment load in the aforementioned region has significantly decreased throughout the post-Soviet period. "The decrease has been especially profound in the forest steppe, a part of which covers the Republic of Tatarstan, because of the combined influence of climate change and land cultivation," explains Gusarov. "To the north of the forest steppe, in the southern part of the boreal zone, the anthropogenic factor was the primary influence on the changes in soil erosion, at least in the east of the East European Plain. ...

As much as 20% of premature mortality can be attributed to poor urban and transport planning. Nevertheless, quantitative indicators to guide the integration of health components into urban design have been lacking. To address this gap, a team from the Barcelona Institute for Global Health (ISGlobal), a centre supported by the "la Caixa" Foundation, has identified 10 principles--and corresponding indicators--to help urban planners incorporate public health into their work. The new study, published in the International Journal of Hygiene and Environmental Health, was undertaken at the request of the Directorate-General for Environmental Policies and the Natural Environment, which forms ...

Organic solar elements with the self-assembling molecular-thin layer (SAM) of hole-transporting material, the technology, which was used in producing a record-breaking tandem solar cell, achieved 18.4 power conversion efficiency. The invention of Lithuanian chemists working at Kaunas University of Technology (KTU), commercialized by several global companies proved versatile and applicable to different solar technologies. Organic solar cells are made of common organic elements such as carbon, hydrogen, nitrogen, fluorine, oxygen, and sulphur. Their raw materials are cheap, abundant, and can ...

The Earth is a sphere, and it comprises spheres: atmosphere, hydrosphere, cryosphere, lithosphere and biosphere -- in short, all of the cycles that interact to influence Earth's weather and climate. Now, to better research how the spheres interact and impact the planet, China is launching EarthLab in Beijing. On June 23, after EarthLab's opening ceremony, researchers will begin trials to demonstrate the facility's ability to integrate simulations and observations to more accurately project outcomes and provide a scientific foundation to predict and mitigate such things as natural weather disasters. EarthLab's ...

A beetle bores a tree trunk to build a gallery in the wood in order to protect its lay. As it digs the tunnel, it spreads ambrosia fungal spores that will feed the larvae. When these bore another tree, the adult beetles will be the transmission vectors of the fungal spores in another habitat. This mutualism among insects and ambrosia fungi could be more than 100 years old --more than what was thought to date-- according to an article published in the journal Biological Reviews. The study analyses for the first time the symbiotic associations and the coevolution between ambrosia fungi and beetles from a paleontological perspective using the Cretaceous ...
