The efficiency of solar cells can be increased by exploiting a phenomenon known as singlet fission. However, unexplained energy losses during the reaction have until now been a major problem. A research group led by scientists at Linköping University, Sweden, has discovered what happens during singlet fission and where the lost energy goes. The results have been published in the journal Cell Reports Physical Science.
(LOS ANGELES) - Non-alcoholic fatty liver disease (NAFLD) is the most prevalent chronic liver disease worldwide. It is found in 30% of people in developed countries and occurs in approximately 25% of people in the United States. Risk factors for the disease include obesity, diabetes, high cholesterol and poor eating habits, although this does not exclude individuals without these risk factors.
WEST LAFAYETTE, Ind. - New contact lens technology to help diagnose and monitor medical conditions may soon be ready for clinical trials.
A team of researchers from Purdue University worked with biomedical, mechanical and chemical engineers, along with clinicians, to develop the novel technology. The team enabled commercial soft contact lenses to be a bioinstrumentation tool for unobtrusive monitoring of clinically important information associated with underlying ocular health conditions.
Native to the southeastern United States, a weedy grass has spread northward to Canada and also made its way to Australia and Japan. Andropogon virginicus grows densely packed and up to seven feet tall, disrupting growth patterns of other plants and competing for resources. When burned, it grows back stronger. There is no way to effectively remove the weed once it has invaded. But there might be a way to use it to human advantage.
Hydrogen has been hailed as the 'fuel of the future' owing to several reasons. First, compared to the conventionally used hydrocarbons, hydrogen exhibits higher energy yield. Second, the commercial use of hydrogen fuel, which yields only water as a byproduct product, would help mitigate the imminent global warming crisis by reducing the use of exhaustible and polluting fossil fuels. Thus, ongoing research has been focusing on efficient and environment-friendly ways to produce of hydrogen fuel.
Mental health issues such as burnout and psychological distress are matters for concern among young adults, and are even more pertinent in today's uncertain global climate. A recent paper by Yale-NUS College alumna Ms Joanna Chue (Class of 2019) and Assistant Professor of Social Sciences (Psychology) Cheung Hoi Shan identified five components of resilience that are applicable in Singapore's cultural context, and demonstrated that college students possessing a higher degree of resilience were less susceptible to burnout and psychological distress.
PHILADELPHIA--Even before the COVID-19 pandemic, mental health issues have been on the rise across the nation, but many struggle to access the care they need. Collaborative care--a proven approach for improving psychiatric care--combats this issue by integrating mental health professionals into the primary care setting. Penn Medicine's collaborative care program, Penn Integrated Care (PIC), utilizes a centralized resource center to facilitate intake, triage, and referral management for all patients with mental health needs.
Researchers at the UAB have designed minimalist biostructures that imitate natural enzymes, capable of carrying out two differentiated and reversibly regulated activities thanks to a unique combination of structural and functional properties. The strategy used opens the door to the creation of "intelligent" nanomaterials with tailor-made combinations of catalytic functions.
Several processes in the human body are regulated by biochemical reactions involving hydrogen peroxide (H2O2). Although it can act as a 'secondary messenger', relaying or amplifying certain signals between cells, H2O2 is generally toxic because of its oxidant character. The latter means that it converts (oxidizes) biochemical molecules like proteins and DNA. The oxidizing property of H2O2 is of potential therapeutic relevance for cancer, though: deliberately causing tumor cells to increase their H2O2 concentration would be a way to destroy them.
The sensor network MUCCnet (Munich Urban Carbon Column network) consists of five high-precision optical instruments that analyze the sun's light spectra. They measure the concentration of the gases carbon dioxide (CO2), methane (CH4) and carbon monoxide (CO). Since each gas has its own unique spectral "fingerprint", concentrations of these gases can be determined in the columns of air between the instruments and the sun.
Research from Queen Mary University of London has concluded that there is convincing evidence that type 2 diabetes is associated with an increased risk of Parkinson's disease. The same study found that there was also evidence that type 2 diabetes may contribute to faster disease progression in patients who already have Parkinson's.
Treating people with drugs already available for type 2 diabetes may reduce the risk and slow the progression of Parkinson's. Screening for and early treatment of type 2 diabetes in patients with Parkinson's may be advisable.
A new fabrication technique could allow solid-state automotive lithium-ion batteries to adopt nonflammable ceramic electrolytes using the same production processes as in batteries made with conventional liquid electrolytes.
The melt-infiltration technology developed by materials science researchers at the Georgia Institute of Technology uses electrolyte materials that can be infiltrated into porous yet densely packed, thermally stable electrodes.
HOUSTON - (March 8, 2021) - Health care teams must prepare for anything, including the unconventional work environments brought about by a global pandemic and social unrest.

Squids have long been a source of fascination for humans, providing the stuff of legend, superstition and myth. And it's no wonder -- their odd appearances and strange intelligence, their mastery of the open ocean can inspire awe in those who see them.
