New model accurately predicts how coasts will be impacted by storms and sea-level rise
2021-07-07
Coastal communities across the world are increasingly facing up to the huge threats posed by a combination of extreme storms and predicted rises in sea levels as a result of global climate change.
However, scientists at the University of Plymouth have developed a simple algorithm-based model which accurately predicts how coastlines could be affected and - as a result - enables communities to identify the actions they might need to take in order to adapt.
The Forecasting Coastal Evolution (ForCE) model has the potential to be a game-changing advance in coastal evolution science, allowing adaptations in the shoreline to be predicted over timescales of anything from days to decades and beyond.
This broad range of timescales means that the model is capable of predicting ...
Brain functional connectivity in Tourette syndrome
2021-07-07
Philadelphia, July 7, 2021 - Tourette syndrome, a neurodevelopmental disorder, causes motor and phonic "tics" or uncontrollable repeated behaviors and vocalizations. People affected by Tourette syndrome can often suppress these tics for some time before the urges become overwhelming, and researchers have long wondered at the neural underpinnings of the suppression effort.
Now, in a new study using a non-invasive technique to measure brain activity called high-density electroencephalography (hdEEG), researchers at Yale School of Medicine have assessed the impact of tic suppression on functional ...
Understanding frailty will lead to better care for older adults
2021-07-07
Frailty is a better predictor than factors such as age when determining how older adults fare one year after receiving critical care.
A team led by researchers from the University of Waterloo analyzed data from more than 24,000 community-dwelling older adults receiving home care in Ontario who were subsequently admitted into an intensive-care unit (ICU).
They applied three different measures for baseline frailty and found that an individual's level of frailty was linked to survival one year later. The most frail ICU survivors had only a one in five chance of living to one year after discharge.
Clinical frailty is age-related and characterized ...
UK public view COVID-19 as a threat because of lockdowns, new study suggests
2021-07-07
The UK public is likely to take the COVID-19 pandemic less seriously once restrictions are lifted, according to new research led by Cardiff University.
Psychologists found lockdown in itself was a primary reason why so many people were willing to abide by the rules from the start - believing the threat must be severe if the government imposes such drastic measures.
The team from Cardiff and the universities of Bath and Essex examined the reasons behind headline polling support for COVID-19 measures. They carried out two UK surveys*, six months apart, during 2020. Their findings are published today in the journal Royal Society Open Science.
Lead author Dr Colin Foad said: "Surprisingly, we found that people judge the severity ...
Methane in the plumes of Saturn's moon Enceladus: Possible signs of life?
2021-07-07
An unknown methane-producing process is likely at work in the hidden ocean beneath the icy shell of Saturn's moon Enceladus, suggests a new study published in Nature Astronomy by scientists at the University of Arizona and Paris Sciences & Lettres University.
Giant water plumes erupting from Enceladus have long fascinated scientists and the public alike, inspiring research and speculation about the vast ocean that is believed to be sandwiched between the moon's rocky core and its icy shell. Flying through the plumes and sampling their chemical makeup, the Cassini spacecraft detected a relatively high concentration of certain molecules associated with hydrothermal vents on the bottom of Earth's oceans, specifically dihydrogen, ...

Secret to weathering climate change lies at our feet
2021-07-06
AMHERST, Mass. - Researchers at the University of Massachusetts Amherst recently discovered that the ability of agricultural grasses to withstand drought is directly related to the health of the microbial community living on their stems, leaves and seeds.
"Microbes do an enormous amount for the grasses that drive the world's agriculture," says Emily Bechtold, a graduate student in UMass Amherst's microbiology department and lead author of the paper recently published in Applied and Environmental Microbiology. "They protect from pathogens, provide the grass with nutrients such as nitrogen, supply hormones to bolster the plant's health and growth, protect from UV radiation ...

mRNA vaccines slash risk of COVID-19 infection by 91% in fully vaccinated people
2021-07-06
People who receive mRNA COVID-19 vaccines are up to 91 percent less likely to develop the disease than those who are unvaccinated, according to a new nationwide study of eight sites, including Salt Lake City. For those few vaccinated people who do still get an infection, or "breakthrough" cases, the study suggests that vaccines reduce the severity of COVID-19 symptoms and shorten its duration.
Researchers say these results are among the first to show that mRNA vaccination benefits even those individuals who experience breakthrough infections.
"One of the unique things about this study is that it measured the secondary benefits of the vaccine," says END ...
Still waiting at an intersection? Banning certain left turns helps traffic flow
2021-07-06
When traffic is clogged at a downtown intersection, there may be a way to reduce some of the congestion: Eliminate a few left turns.
According to Vikash Gayah, associate professor of civil engineering at Penn State, well-placed left-turn restrictions in certain busy intersections could loosen many of the bottlenecks that hamper traffic efficiency. He recently created a new method that could help cities identify where to restrict these turns to improve overall traffic flow.
"We have all experienced that feeling of getting stuck waiting to make a left turn," Gayah said. "And ...
Simple blood tests may help improve malaria diagnosis in clinical studies
2021-07-06
Using simple blood tests could help researchers identify children who have been misidentified as having severe malaria, according to a study published today in eLife.
Researchers are working to develop better ways to treat severe malaria, which kills about 400,000 children in Africa each year. The discovery could help expedite such research by helping them more accurately identify children with severe malaria. It also reinforces the importance of the World Health Organization's recommendation that all children being treated for severe malaria also receive antibiotics to ensure any misdiagnosed children receive life-saving care.
Diagnosing severe malaria in children in Africa is challenging because the ...
Enzyme from fungi shows molecules which way to turn
2021-07-06
HOUSTON - (July 6, 2021) - A small fungal enzyme could play a significant role in simplifying the development and manufacture of drugs, according to Rice University scientists.
The Rice lab of chemical and biomolecular engineer Xue Sherry Gao and collaborators isolated a biocatalyst known as CtdE after identifying it as the natural mechanism that controls the chirality -- the left- or right-handedness -- of compounds produced by the native fungal host.
The open-access study appears in Nature Communications.
Two chiral things are, like hands, alike in structure but cannot perfectly ...
Why men take more risks than women
2021-07-06
Researchers from HSE University and Max Planck Institute for Human Cognitive and Brain Sciences have discovered how the theta rhythm of the brain and the gender differences in attitudes to risk are linked. In an article published in the journal Frontiers in Neuroscience, the researchers addressed which processes can be explained by knowing this connection. https://www.frontiersin.org/articles/10.3389/fnins.2021.608699/full

Predicting the future of cod
2021-07-06
The future of cod stocks in the North Sea and the Barents Sea may be much easier to predict than before. This is the result of an international research project led by the Helmholtz-Zentrum Hereon and its Institute of Coastal Systems - Analysis and Modeling. For the first time, the team has succeeded in predicting the development of stocks for ten years in advance, taking into account both changes due to climate and fishing. Traditionally, fisheries experts provide catch recommendations for about a year in advance, on the basis of which fishing quotas are negotiated and set internationally. This involves first estimating the size of current cod stocks and then calculating how much cod can be caught in the coming year without endangering the stocks ...
Acid sensor discovered in plants
2021-07-06
Climate change is causing increased flooding and prolonged waterlogging in northern Europe, but also in many other parts of the world. This can damage meadow grasses, field crops or other plants - their leaves die, the roots rot.
The damage is caused by a lack of oxygen and the accumulation of acids. How do plants perceive this over-acidification, how do they react to it? This is what researchers from Würzburg, Jena (Germany) and Talca (Chile) describe in the journal Current Biology.
Biophysicists Dr. Tobias Maierhofer and Professor Rainer Hedrich from the Chair of Molecular Plant Physiology and Biophysics at Julius-Maximilians-Universität ...
Ultrathin semiconductors electrically connected to superconductors for the first time
2021-07-06
For the first time, University of Basel researchers have equipped an ultrathin semiconductor with superconducting contacts. These extremely thin materials with novel electronic and optical properties could pave the way for previously unimagined applications. Combined with superconductors, they are expected to give rise to new quantum phenomena and find use in quantum technology.
Whether in smartphones, televisions or building technology, semiconductors play a central role in electronics and therefore in our everyday lives. In contrast to metals, it is possible to adjust their electrical conductivity by applying a voltage and hence to switch the current flow on and off.
With a view to future applications in electronics and quantum technology, researchers are focusing on the development ...
NYU Abu Dhabi researchers unlock secrets behind liver regrowth and regenerative medicine
2021-07-06
Abu Dhabi, UAE, July 5, 2021: NYU Abu Dhabi (NYUAD) researchers uncovered a code that sets the genome of the liver to account for the remarkable ability for this organ to regenerate. This finding offers new insight into how the specific genes that promote regeneration can be activated when part of the liver is removed. These findings have the potential to inform the development of a new form of regenerative medicine that could help non-regenerative organs regrow in mice and humans.
While other animals can regenerate most organs, humans, mice, and other mammals can only regenerate their liver in response to an injury or when a piece is removed. NYUAD researchers ...
Work like a dream: new anticholinergic drug keeps PTSD flashbacks and nightmares away
2021-07-06
Post-traumatic stress disorder (PTSD) rings a bell for many, due to its rampant references in pop culture, and more, importantly, its prevalence in today's society. It is only probable that this disorder, which develops after shocking or dangerous events, would unfortunately affect the lives of many people. Medical researchers have been hard at work trying to come up with solutions to combat this condition and its manifestations effectively. Unfortunately, the neurological mechanisms of PTSD aren't clear, and without knowing this exactly, trying to find a cure is a shot in the dark.
Fortunately, a group ...
From eyebrow beans to 'lost' rice: community seedbanks are protecting China's crops
2021-07-06
"Plant a hundred kinds of crops"
Wangjinzhuang village is nestled amongst the steep slopes of the South Taihang Mountains in Hebei Province, China. To prosper in the northern climate, the villagers have developed a tried-and-true strategy: "using the land to plant a hundred kinds of crops and not rely on the sky". Their fields contain red millet, white sorghum, purple and green eyebrow beans, and yellow radishes. Having survived for over a thousand years, this agrobiodiversity is a vibrant cornerstone of the village's agricultural heritage that is too precious to lose.
In an effort to combat dwindling crop diversity across China (the Ministry of Agriculture found that of 11,590 grain crop varieties planted ...

About half of people living with HIV have coronary artery plaque despite low cardiac risk
2021-07-06
BOSTON - Significant amounts of atherosclerotic plaque have been found in the coronary arteries of people with HIV, even in those considered by traditional measures to be at low-to-moderate risk of future heart disease, according to a study published in JAMA Network Open.
This finding emerged from the global REPRIEVE (Randomized Trial to Prevent Vascular Events in HIV) study, in which Massachusetts General Hospital (MGH) is playing a key coordinating role. Researchers found that the higher-than-expected levels of plaque could not be attributed simply to traditional cardiovascular disease risk factors like smoking, hypertension, and lipids in the blood, but were independently related to increased arterial inflammation ...
What to do with food waste? Well, that depends
2021-07-06
The expected decline in the number of landfills across the United States coupled with bans on disposing large amounts of organic waste in landfills that have been enacted in multiple states has prompted researchers at the U.S. Department of Energy's (DOE's) National Renewable Energy Laboratory (NREL) to examine other ways to grapple with the issue of food waste disposal.
The researchers determined no single solution exists in the United States for dealing with food waste disposal. NREL researchers Alex Badgett and Anelia Milbrandt came to that conclusion after examining the economics involved in five different ways to ...
