ALBUQUERQUE, N.M. -- Geoscientists at Sandia National Laboratories used 3D-printed rocks and an advanced, large-scale computer model of past earthquakes to understand and prevent earthquakes triggered by energy exploration. Injecting water underground after unconventional oil and gas extraction, commonly known as fracking, geothermal energy stimulation and carbon dioxide sequestration all can trigger earthquakes. Of course, energy companies do their due diligence to check for faults -- breaks in the earth's upper crust that are prone to earthquakes -- but sometimes ...

Eye contact is a key to establishing a connection, and teachers use it often to encourage participation. But can a robot do this too? Can it draw a response simply by making "eye" contact, even with people who are less inclined to speak up. A recent study suggests that it can. Researchers at KTH Royal Institute of Technology published results of experiments in which robots led a Swedish word game with individuals whose proficiency in the Nordic language was varied. They found that by redirecting its gaze to less proficient players, a robot can elicit involvement from even the most reluctant participants. Researchers Sarah Gillet and Ronald Cumbal say the results offer evidence that robots could play a productive role in educational settings. Calling on someone by name isn't ...

The protein α-synuclein is one of the most abundant proteins in the human brain. It is often referred to as the "Parkinson protein", as deposition of this protein in brain cells is a hallmark of Parkinson's disease. Despite the high interest of biomedical research in the protein, many questions concerning the function and physiology of α-synuclein in living cells still remain to be answered. For example, it was previously unclear whether and to what extent the protein binds to and interacts with internal cell components such as membranes. As such processes could play a role in the development of the disease, the team led by Konstanz-based physical chemist Professor Malte Drescher used the further development of an established measurement method called ...

An article published by the researchers of the Biodiversity Unit at the University of Turku, Finland, highlights how amateur venom-extraction business is threatening scorpion species. Sustainably produced scorpion venoms are important, for example, in the pharmacological industry. However, in the recent years, there has been a dramatic increase in the number of people involved in the trade and vast numbers of scorpions are harvested from nature. This development is endangering the future of several scorpion species in a number of areas. Scorpions have existed on Earth for over 430 million years. Currently comprising over 2,500 extant species, scorpions occur on almost all the major landmasses in a range of habitats from ...

Gravity is the weakest of all known forces in nature - and yet it is most strongly present in our everyday lives. Every ball we throw, every coin we drop - all objects are attracted by the Earth's gravity. In a vacuum, all objects near the Earth's surface fall with the same acceleration: their velocity increases by about 9.8 m/s every second. The strength of gravity is determined by the mass of the Earth and the distance from the center. On the Moon, which is about 80 times lighter and almost 4 times smaller than the Earth, all objects fall 6 times slower. And on a planet of the size of a ladybug? ...

A new study published Tuesday 10 March, No Smoking Day, from King's College London highlights the 'clear benefit' of using e-cigarettes daily in order to quit smoking, and supports their effectiveness when compared to other methods of quitting, including nicotine replacement therapy or medication. Although the number of people in England who smoke has continued to fall in recent years, tobacco smoking is still the leading preventable cause of premature death and disease - killing nearly 75,000 people in England in 2019. While e-cigarettes have been around for more than a decade, evidence on their effectiveness for helping people to ...

There's a surprising amount of information stored in the hardened plaque, or calculus, between teeth. And if that calculus belongs to the remains of a person who lived in ancient times, the information could reveal new insights about the past. But the tiny samples can be difficult to work with. Now, in ACS' Journal of Proteome Research, scientists apply a new method to this analysis, finding more proteins than traditional approaches. The human mouth is full of interesting molecules: DNA and enzymes in saliva, proteins and lipids from bits of food stuck between teeth, the bacterial ...

Amsterdam, NL, March 10, 2021 - Music-based interventions have become a core ingredient of effective neurorehabilitation in the past 20 years thanks to the growing body of knowledge. In this END ...

People are different. New technology is good for patients and the healthcare system. But it could also expand the already significant health disparities in Norway and other countries. "Women and men with higher education in Norway live five to six years longer than people with that only have lower secondary school education," says Emil Øversveen, a postdoctoral fellow at the Norwegian University of Science and Technology's (NTNU) Department of Sociology and Political Science. He is affiliated with CHAIN, the Centre for Global Health Inequalities Research. The centre works to reduce social health ...

In the dry air and soil of Texas' Southern High Plains, improving soil health can be tough. We usually think of healthy soil as moist and loose with lots of organic matter. But this can be hard to achieve in this arid area of Texas. Lindsey Slaughter, a member of the Soil Science Society of America, set out with her fellow researchers to test a solution that kills two birds with one stone. They put excess cow manure on these soils to see if they could make them healthier. The team recently published their research in the Soil Science Society of America Journal. "We know that planting perennial grasslands for cattle production can help protect and restore soil in semi-arid lands that are likely to erode and degrade from intense ...

The per-capita rates of new COVID-19 cases and COVID-19 deaths were higher in states with Democrat governors in the first months of the pandemic last year, but became much higher in states with Republican governors by mid-summer and through 2020, possibly reflecting COVID-19 policy differences between GOP- and Democrat-led states, according to a study led by researchers at the Johns Hopkins Bloomberg School of Public Health and the Medical University of South Carolina. For their study, the researchers analyzed data on SARS-CoV-2-positive nasal swab tests, COVID-19 diagnoses, and COVID-19 ...

Immune cells specialize to ensure the most efficient defense against viruses and other pathogens. Researchers at the University of Basel have shed light on this specialization of T cells and shown that it occurs differently in the context of an acute and a chronic infection. This could be relevant for new approaches against chronic viral infections. Researchers led by Professor Carolyn King of the University of Basel have developed a method to study the specialization of T cells in the context of infections. In the journal eLife, they report the different directions ...

According to the researchers, they have synthesized a new nanomaterial that can replace low-efficiency graphite used in lithium-ion batteries today. The results of the research are published in the Journal of Alloys and Compounds. Lithium-ion batteries are widely used for household appliances from smartphones to electric vehicles. The charge-discharge cycle in such battery is provided by ...

As plastic debris weathers in aquatic environments, it can shed tiny nanoplastics. Although scientists have a good understanding of how these particles form, they still don't have a good grasp of where all the fragments end up. Now, researchers reporting in ACS' Environmental Science & Technology have shown experimentally that most nanoplastics in estuarine waters can clump, forming larger clusters that either settle or stick to solid objects, instead of floating on into the ocean. There is a huge discrepancy between the millions of tons of plastic waste entering rivers and streams and the amount researchers have found in the oceans. As large pieces of plastic break apart into ...

The mosquito protein AEG12 strongly inhibits the family of viruses that cause yellow fever, dengue, West Nile, and Zika and weakly inhibits coronaviruses, according to scientists at the National Institutes of Health (NIH) and their collaborators. The researchers found that AEG12 works by destabilizing the viral envelope, breaking its protective covering. Although the protein does not affect viruses that do not have an envelope, such as those that cause pink eye and bladder infections, the findings could lead to therapeutics against viruses that affect millions of people around the world. The research ...

Throughout history, leather has been a popular material for clothes and many other goods. However, the tanning process and use of livestock mean that it has a large environmental footprint, leading consumers and manufacturers alike to seek out alternatives. An article in Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society, details how sustainable materials are giving traditional leather a run for its money. Traditional leather goods are known for their durability, flexibility and attractive finish, with a global market worth billions, writes ...

Since its introduction, the emerald ash borer (EAB) has become the most devastating invasive forest insect in the United States, killing hundreds of millions of ash trees at a cost of hundreds of millions of dollars. Now, new research from the University of Minnesota's Minnesota Invasive Terrestrial Plants and Pests Center (MITPPC) shows a possible path forward in controlling the invasive pest that threatens Minnesota's nearly one billion ash trees. In a recent study published in Fungal Biology, MITPPC researchers identified various fungi living in EAB-infested trees -- a critical ...

Energy-efficient light-emitting diodes (LEDs) have been used in our everyday life for many decades. But the quest for better LEDs, offering both lower costs and brighter colours, has recently drawn scientists to a material called perovskite. A recent joint-research project co-led by the scientist from City University of Hong Kong (CityU) has now developed a 2D perovskite material for the most efficient LEDs. From household lighting to mobile phone displays, from pinpoint lighting needed for endoscopy procedures to light source to grow vegetables in Space, LEDs ...

Hip fractures are serious, especially for the elderly. The operation can be a great strain, and 13 per cent of patients over the age of 70 do not survive 60 days after the fracture. Their chance of survival may depend on how busy the surgeons are with other emergency procedures. "When the operating room is busy, 20 per cent more of the patients die within 60 days after the operation," says Professor Johan Håkon Bjørngaard at the Norwegian University of Science and Technology's (NTNU) Department of Public Health and Nursing. Surgeons can get especially busy during periods when the patient demand for surgery is high. In busy periods, hip fracture patients ...

Bone is not just a fixed material - it's a dynamic set of structures that can adapt their mass and strength based on the loads they must support. Developing that sort of adaptive material has long been the dream of scientists. Now for the first time, scientists at the Pritzker School of Molecular Engineering (PME) at the University of Chicago have developed a gel material that strengthens when exposed to vibration. Not only were scientists able to make the material 66 times stronger through vibrations, they were also able to strengthen only the areas exposed to movement. That sort of specificity could lead to new adhesives and ...

Scientists have developed a see-through glass display with a high white light contrast ratio that smoothly transitions between a broad spectrum of colors when electrically charged. The technology, from researchers at Jilin University in Changchun, China, overcomes limitations of existing electrochromic devices by harnessing interactions between metal ions and ligands, opening the door for numerous future applications. The work appears March 10 in the journal Chem. "We believe that the method behind this see-through, non-emissive display may accelerate the development of transparent, eye-friendly displays with improved readability for bright working conditions," says Yu-Mo Zhang, an associate professor of chemistry at Jilin ...

The cryptocurrency market has been abuzz as Bitcoin gains popularity with investors, reaching an all-time high of over $58,000 apiece in February. In a commentary published March 10 in the journal Joule, financial economist Alex de Vries quantifies how the surging Bitcoin price is driving increasing energy consumption, exacerbating the global shortage of chips, and even threatening international safety. Theoretically, any computer with access to the internet and electricity can "mine" Bitcoin, a process to receive cryptocurrency by solving sophisticated mathematical equations. It is estimated that all miners combined make over 150 quintillion--that is 18 zeros following 150--attempts every second to solve the equation, according to numbers from January 11, 2021. Computational power ...

Scientists and healthcare providers are beginning to use a new approach for assessing a person's inherited risk for diseases like Type 2 diabetes, coronary heart disease and breast cancer, which involves calculating a END ...

When we think about the causes of neurological disorders and how to treat them, we think about targeting the brain. But is this the best or only way? Maybe not. New research by scientists at Baylor College of Medicine suggests that microbes in the gut may contribute to certain symptoms associated with complex neurological disorders. The findings, published in the journal Cell, also suggest that microbe-inspired therapies may one day help to treat them. Dr. Mauro Costa-Mattioli, professor and Cullen Foundation Endowed Chair in neuroscience and director of the Memory and Brain Research Center at Baylor, discovered ...

Ottawa, March 10, 2021 - A new study of fossilized lampreys dating from more than 300 million years ago is challenging a long-held theory about the evolutionary origin of vertebrates (all animals with a backbone). The findings are published March 10 in the science journal Nature. Lampreys are ancient, jawless, eel-like fishes that arose around half a billion years ago and they have long provided insights into vertebrate evolution. Now, scientists with the Canadian Museum of Nature, the University of Chicago and the Albany Museum in South Africa are reporting their analysis of dozens of tiny fossils that track the life stages and growth of ancient lampreys, from hatchlings to juveniles to adults. Their results counter the established view that the blind, filter-feeding ...
