Anxiety levels in the United States are rising sharply and have especially intensified in younger populations. According to the Anxiety and Depression Association of America, anxiety disorders affect 31.9 percent of children ages 13 to 18 years old. Because of the COVID-19 pandemic, children and adolescents have experienced unprecedented interruptions to their daily lives and it is expected that these disruptions may precipitate mental illness, including anxiety, depression, and/or stress related symptoms. Traditional anxiety and depression treatments include ...

A critical ingredient for auroras exists much higher in space than previously thought, according to new research in the journal Scientific Reports. The dazzling light displays in the polar night skies require an electric accelerator to propel charged particles down through the atmosphere. Scientists at Nagoya University and colleagues in Japan, Taiwan and the US have found that it exists beyond 30,000 kilometres above the Earth's surface - offering insight not just about Earth, but other planets as well. The story of aurora formation begins with supersonic plasma propelled from the Sun into space as high-speed, charged particles. When these charged particles get close to Earth, they are ...

Scientists at the University of Virginia School of Medicine have developed a tool to monitor communications within the brain in a way never before possible, and it has already offered an explanation for why Alzheimer's drugs have limited effectiveness and why patients get much worse after going off of them. The researchers expect their new method will have tremendous impact on our understanding of depression, sleep disorders, autism, neurological diseases and major psychiatric conditions. It will speed scientific research into the workings of the brain, they say, and facilitate the development of new treatments. "We can now 'see' how brain cells communicate in sharp detail in both the healthy and diseased brains," said lead researcher J. Julius Zhu, PhD, of UVA's Department ...

(LOS ANGELES) - Recent advances in technology have opened many possibilities for using wearable and implantable sensors to monitor various indicators of patient health. Wearable pressure sensors are designed to respond to very small changes in bodily pressure, so that physical functions such as pulse rate, blood pressure, breathing rates and even subtle changes in vocal cord vibrations can be monitored in real time with a high degree of sensitivity. Such responses occur when a substance in the sensor "gates," or allows selected pressure signals to pass to a transistor, which then conducts and amplifies these signals for detection. A recent type of transistor, organic electrochemical transistors ...

Visual sensation begins at the retina, which is the neural tissue located at the back of eyeballs. It has been known that the retina detects light using photoreceptors which are light-sensitive nerve cells.In case of retinal degenerative diseases such as retinitis pigmentosa and age-related macular degeneration, those light sensing neurons are gradually damaged, leading to a profound vision loss. At this moment, no cure is available for the abovementioned ailments. But, microelectronic retinal prostheses can create artificial vision by electrically stimulating remaining retinal neurons although the prosthetic vision is still far removed from normal vision. To further improve the quality of prosthetic artificial vision, Dr. Maesoon ...

A staple for many, chickpeas are a rich source of vitamins, minerals, and fiber and offer many health benefits, such as improving digestion and reducing the risk of ailments including heart disease and cancer. However, chickpeas possess a rather narrow genetic diversity and are susceptible to Ascochyta blight, a devastating disease that can cause a yield loss of up to 100 percent. In Australia alone, this disease costs an average of $4.8 million annually. To help curtail the impact of Ascochyta blight, plant pathologists in Western Australia have turned to wild relatives of the ...

In the spring of 2020, the outbreak of the coronavirus pandemic appeared to coincide with the tree pollen season in the northern hemisphere. These observations prompted an international team of researchers to conduct an extensive investigation: The scientists wanted to know whether there is a demonstrable link between airborne pollen concentrations and SARS-CoV-2 infection rates. Pollen is a significant environmental factor influencing infection rates Under the leadership of first author Athanasios Damialis, the team at the Chair of Environmental Medicine at TUM collected data on airborne pollen concentrations, weather conditions and SARS-CoV-2 infections - taking into consideration the variation of infection rates from ...

Depending on the topic, people's attitudes can change from moment to moment or last a lifetime. The factors that make one opinion long-lasting and another ephemeral, however, are not always clear. Past studies have demonstrated that opinions based on hard facts and data can remain constant over time, but new research published in the journal Psychological Science reveals that attitudes based on feelings and emotions can also stand the test of time. This research has implications for both predicting whose attitudes are fixed versus fleeting and how to nudge people to form more long-lasting opinions. "We have ...

Washington, March 9, 2021--A comprehensive meta-analysis of prior research has found, overall, that children ages 1 to 8 were less likely to understand picture books when they read the digital, versus print, version. However, when digital picture books contain the right enhancements that reinforce the story content, they outperform their print counterparts. The results were published today in Review of Educational Research, a peer-reviewed journal of the American Educational Research Association. Authors Natalia Kucirkova at the University of Stavanger in Norway and The Open University in the United Kingdom, and May Irene Furenes and Adriana G. Bus at the University of Stavanger, analyzed the results of 39 studies that included a total 1,812 children between the ages of 1 and 8. For their ...

Imagine using stem cells from your bone marrow to grow a piece of bone tissue in the lab, after which medical doctors explore which drugs have the desired effect on your bones. In this way, a tailor-made treatment plan would be made for everyone, with the best approach being clear in advance. Personalized medicine at its best. That vision of the future is no longer science fiction now that researchers from Eindhoven University of Technology and Radboud university medical center have actually realized the first part: growing a lifelike piece of bone tissue from human stem cells. It is the first organoid of bone, a simplified version of the original, the researchers report today in the journal Advanced Functional Materials. Coherent picture "With ...

Smart speakers, such as Amazon Echo and Google Home, have proven adept at monitoring certain health care issues at home. For example, researchers at the University of Washington have shown that these devices can detect cardiac arrests or monitor babies breathing. But what about tracking something even smaller: the minute motion of individual heartbeats in a person sitting in front of a smart speaker? UW researchers have developed a new skill for a smart speaker that for the first time monitors both regular and irregular heartbeats without physical contact. The system sends inaudible sounds from the speaker out into ...

Nanoengineers at the University of California San Diego have developed a "wearable microgrid" that harvests and stores energy from the human body to power small electronics. It consists of three main parts: sweat-powered biofuel cells, motion-powered devices called triboelectric generators, and energy-storing supercapacitors. All parts are flexible, washable and can be screen printed onto clothing. The technology, reported in a paper published Mar. 9 in Nature Communications, draws inspiration from community microgrids. "We're applying the concept of the microgrid to create wearable systems that are powered sustainably, reliably and independently," said co-first author Lu Yin, a nanoengineering Ph.D. student ...

Charcot-Marie Tooth disease is the most common hereditary neurological disease in the world. It affects the peripheral nerves and causes progressive paralysis of the legs and hands. No treatment is currently available to fight this disease, which is due to the overexpression of a specific protein. Scientists from the CNRS, INSERM, the AP-HP and the Paris-Saclay and Paris universities have developed a therapy based on degrading the coding RNA for this protein in mice. Their work is patented and was published on 9 March 2021 in Communications Biology. In molecular biology, transcription is when a DNA molecule is copied to make an RNA molecule. This RNA molecule is then "translated" into a protein, which can perform different functions within the body's cells. When a specific protein called ...

Modern hospitals and antibiotic treatment alone did not create all the antibiotic resistant strains of bacteria we see today. Instead, selection pressures from before widespread use of antibiotics influenced some of them to develop, new research has discovered. By using analytical and sequencing technology that has only been developed in recent years, scientists from Wellcome Sanger Institute, University of Oslo and University of Cambridge have created an evolutionary timeline of the bacterium, Enterococcus faecalis, which is a common bacterium that can cause antibiotic resistant infections in hospitals. The results, published today (9th March 2021) in Nature Communications ...

An increase in overall hospitalizations was reported for older adults in the week following exposure to a tropical cyclone, according to a new study by researchers at Columbia University Mailman School of Public Health, Columbia University's Earth Institute and colleagues at Colorado State University and Harvard T. H. Chan School of Public Health. The researchers used data over 16 years on 70 million Medicare hospitalizations and a comprehensive database of county-level local winds associated with tropical cyclones to examine how tropical cyclone wind exposures ...

Luxembourg, 9 March 2021 - Today, Alzheimer Europe launches a new report, "Legal capacity and decision making: The ethical implications of lack of legal capacity on the lives of people with dementia", which looks at the intersection between legal rights and ethical considerations in relation to legal capacity and decision making. The working group responsible for the report was set up by Alzheimer Europe in 2020 and was composed of experts in dementia, law, ethics, policy, research, psychology and the experience of having dementia and supporting people with ...

MUNICH -- Around the world each year, extreme precipitation events cause catastrophic flooding that results in tragic loss of life and costly damage to infrastructure and property. However, a variety of different weather systems can cause these extreme events, so a detailed understanding of the atmospheric processes that lead to their formation is crucial. Now, for the first time, a global analysis reveals that two intertwined atmospheric processes drive the formation of many large-scale extreme precipitation events around the world, particularly in dry subtropical regions where they can inflict catastrophic flooding, as occurred in March 2015 in the Atacama Desert. Previous research on extreme precipitation events ...

CHAMPAIGN, Ill. -- A six-week training program designed to strengthen resilience against emotional distress in military veterans was associated with positive changes in brain function and increased confidence in their ability to regulate emotions, researchers report. Published in the journal Frontiers in Psychology, the new proof-of-concept study tested two approaches for building emotional resilience in 19 veterans. The first involved weekly, 90-minute group therapy sessions focused on sharing and skills-building in 10 participants. The second trained nine veterans in the use of specific emotion-regulation strategies that previous ...

CHARLOTTESVILLE, VA (MARCH 9, 2021). In 2014, the Journal of Neurosurgery published a paper by a group of researchers from Baylor College of Medicine in Houston, who developed a prognostic scoring system for use in patients who present to the emergency department with a gunshot wound to the head (GSWH).[1] Today, we publish two papers by a group of researchers at Vanderbilt University Medical Center that extend our understanding of the Baylor GSWH scoring system and its application, externally validating it in a different group of patients presenting during a more recent time period in which ...

People living with a patient undergoing an intensive weight loss treatment also benefit from this therapy. This has been demonstrated by a team of researchers from the Hospital del Mar Medical Research Institute (IMIM-Hospital del Mar) along with doctors from Hospital del Mar and the CIBER on the Physiopathology of Obesity and Nutrition (CIBERObn), in collaboration with IDIAPJGol, the Pere Virgili Health Research Institute (IISPV), IDIBELL, IDIBAPS and the Sant Joan de Reus University Hospital. The study has been published in the journal International Journal of Obesity. The study analysed data ...

About 11% of women who carry to term will experience prelabor rupture of membrane--a condition where the amniotic sac breaks open early, but labor doesn't begin. Typically, when a woman's water breaks but labor doesn't start, labor is induced. But a new University of Michigan study found that expectant management--waiting a period of time after the water breaks for labor to begin spontaneously--did not significantly increase risk to the fetus or the mother in healthy pregnancies. Therefore, both induction and expectant management should be considered, and the decision should be made in the context of the mother's wishes and health, said study ...

People who frequently try to impress or persuade others with misleading exaggerations and distortions are themselves more likely to be fooled by impressive-sounding misinformation, new research from the University of Waterloo shows. The researchers found that people who frequently engage in "persuasive bullshitting" were actually quite poor at identifying it. Specifically, they had trouble distinguishing intentionally profound or scientifically accurate fact from impressive but meaningless fiction. Importantly, these frequent BSers are also much more likely to fall for fake news headlines. "It probably seems intuitive to believe that you can't bullshit ...

The rapid spread of SARS-CoV2 (COVID-19) has not only left societies with a high number of excess deaths and a wide range of health consequences, but also taken a heavy toll on wider global economies - impacting other sectors outside health. Future analysis must take into account societal impacts of a wide range of responses to COVID-19, if policymakers are to take better decisions about resource allocation, intervention implementation and boosting economic and social recovery. In practice, many health economic evaluations tend to adopt a narrow study perspective predominantly estimating the economic impact around healthcare costs. They fail ...

Digital COVID-19 'symptom checkers' may stop some patients from getting prompt treatment for serious illness, suggests an international case simulation study, published in the online journal BMJ Health & Care Informatics. Both the US and UK symptom checkers consistently failed to identify the symptoms of severe COVID-19, bacterial pneumonia, and sepsis, frequently advising these cases to stay home, the findings indicate. The availability and use of symptom checkers is on the rise, and they are currently being used at a national level to pick up COVID-19 infection. Identifying which patients with COVID-19 require treatment is difficult, because the infection can mimic common conditions ...
