Human brain can process a massive number of light/spectral signals at high speed, partly because it perceives lights as a combination of colors and intensities. However, the existing photodetectors can only indicate light intensities. It was recently reported that integrating dozens of photodetectors with semiconductors presenting different bandgaps can reconstruct spectral curves of incident lights.
The understanding of unconventional superconductivity is one of the most challenging and fascinating tasks of solid-state physics. Different classes of unconventional superconductors share that superconductivity emerges near a magnetic phase despite the underlying physics is different. Two of these unconventional materials are the heavy-fermion and the iron-based superconductors.
Cataclysmic astrophysical events such as black hole mergers could release energy in unexpected forms. Exotic low-mass fields (ELFs), for example, could propagate through space and cause feeble signals detectable with quantum sensor networks such as the atomic clocks of the GPS network or the magnetometers of the GNOME network. These are the results of theoretical calculations undertaken by a research group including Dr. Arne Wickenbrock of the PRISMA+ Cluster of Excellence at Johannes Gutenberg University Mainz (JGU) and the Helmholtz Institute Mainz (HIM).
Announcing a new article publication for BIO Integration journal. In this review article the authors Yun Chen, Gongfa Jiang, Yue Li, Yutao Tang, Yanfang Xu, Siqi Ding, Yanqi Xin and Yao Lu from Xiangtan University, Xiangtan, China and Sun Yat-sen University, Guangzhou, China consider the application of artificial intelligence imaging analysis methods for COVID-19 clinical diagnosis.
Thermoelectric materials can turn a temperature difference into electricity. Organic thermoelectric materials could be used to power wearable electronics or sensors; however, the power output is still very low. An international team led by Jan Anton Koster, Professor of Semiconductor Physics at the University of Groningen, has now produced an n-type organic semiconductor with superior properties that brings these applications a big step closer. Their results were published in the journal Nature Communications on 10 November.
Solar power is an eco-friendly alternative to conventional, non-renewable sources of energy. However, current solar panels require the use of toxic materials as buffers, which is not sustainable. To this end, a team of scientists in Korea developed a new eco-friendly alternative, called the ZTO buffer, which can overcome this limitation. This new development to make solar panels even more sustainable is indeed a cherry on top.
A new study from researchers in the Perelman School of Medicine at the University of Pennsylvania and Independence Blue Cross shows that when patients' primary care doctors were able to photograph areas of concern and share them with dermatologists, the response time for a consultation dropped from almost 84 days to under five hours. In addition, the study did not show any undue increases in utilization or cost that might be prohibitive to making the practice widespread. The findings were published today in Telemedicine and e-Health.
New source of lymphatic system leak discovered in children with rare open heart surgery complication
WILMINGTON, Del. (November 11, 2020) - Interventional radiologists with Nemours Children's Health System have identified a new source of abnormal lymphatic flow between the liver and the lungs that may be responsible for some cases of plastic bronchitis. Plastic bronchitis is a rare but serious late complication in patients with congenital heart disease who had Fontan surgery. A report detailing the discovery of this fluid leak, and successful treatment of two cases was published in European Heart Journal.
A team from City, University of London's Department of Engineering believes that a new approach to generating energy through waste heat could yield important insights into delivering environmentally-friendly power.
In this recent paper, Making the case for cascaded organic Rankine cycles for waste-heat recovery, published in the Energy journal, Dr Martin White has identified optimal single-stage and cascaded organic Rankine cycle systems (ORC) to maximise performance, and has designed accompanying heat exchangers.
Wales faces a wave of mental health problems in the wake of Covid-19, with younger adults, women and people from deprived areas suffering the most.
That is the warning contained in new research, led by Swansea University's Professor Nicola Gray and Cardiff University's Professor Robert Snowden, which examines the pandemic's impact on the mental wellbeing of the Welsh population.
The initial findings of the survey reveal that around half of the 13,000 participants showed clinically significant psychological distress, with around 20 per cent suffering severe effects.
Racially diverse congregations have more than tripled in the United States over the past 20 years, and the percentage of all-white congregations has declined, according to a study by a Baylor University sociologist and two colleagues.
Approximately a quarter of evangelical and Catholic churches are now multiracial -- defined as those in which no one racial or ethnic group comprises more than 80% of the congregants.
Mammal defaunation – the loss of mammals to extinction, extirpation and population decline – in the Neotropics and its adverse effects is the focus for two scientific papers produced recently by a group of scientists led by Juliano André Bogoni, an ecologist at the University of São Paulo (USP) in Brazil. The Neotropical realm extends south from the Mexican desert into South America as far as the Sub-Antarctic zone.
UNIVERSITY PARK, Pa. -- Self-reports of smell and taste changes provide earlier markers of the spread of infection of SARS-CoV-2 than current governmental indicators, according to an international team of researchers. The researchers also observed a decline in self-reports of smell and taste changes as early as five days after lockdown enforcement, with faster declines reported in countries that adopted the most stringent lockdown measures.
LA JOLLA--Every day, ten Americans die from asthma. While quick-acting inhalers and medications can reduce inflammation during an asthma attack, people with asthma have few tools to prevent the next attack from coming.
Now researchers at La Jolla Institute for Immunology (LJI) have discovered that blocking two immune molecules at the same time is key to preventing asthma attacks in a mouse model.
Researchers studying the Bering and Chukchi seas for three weeks in October found no ice and a surprisingly active ecosystem as they added another year's data to a key climate change record.
The research vessel Norseman II carried scientists from the University of Alaska Fairbanks, the University of Maryland Center for Environmental Science and Clark University.
