X-ray imaging has been actively utilized in the fields of industrial material inspection, medical diagnosis and scientific research. The key component to detect X-ray is the scintillator which can convert X-ray photons to visible photons and then be detected by a photodiode array. Despite of decades of intensive research of scintillators, the performances of conventional scintillators are still far from ideal.
A new study published in the Journal of Alzheimer's Disease provides insight into the association of blood markers of diabetes with brain beta-amyloid accumulation among older people at risk of dementia. The results suggest a link between Alzheimer's pathology, lower levels of insulin and lower insulin resistance.
At the start of a COVID-19 infection, the coronavirus SARS-CoV-2 docks onto human cells using the spike-like proteins on its surface. The spike protein is at the centre of vaccine development because it triggers an immune response in humans.
DALLAS - Aug. 18, 2020 - The amount of calcified plaque in the heart's arteries is a better predictor of future heart attacks than of strokes, with similar findings across sex and racial groups, according to new research from UT Southwestern.
In 2020 China plans to launch the largest battery complex in the world with a capacity of 800 MW*h (approximately this amount of energy per year is consumed by a household with 200 apartments). This complex is based not on the usual lithium-ion or lead-acid batteries, but on the redox flow battery where the electricity is stored in the form of chemical energy of solutions - electrolytes.
Scientists have revealed how nanomaterials inspired by insect wings are able to destroy bacteria on contact.
The wings of cicadas and dragonflies are natural bacteria killers, a phenomenon that has spurred researchers searching for ways to defeat drug-resistant superbugs.
New anti-bacterial surfaces are being developed, featuring different nanopatterns that mimic the deadly action of insect wings, but scientists are only beginning to unravel the mysteries of how they work.
BLOOMINGTON, Ind. -- About $7 billion reportedly will be spent this fall on television and digital commercials from political campaigns and political action committees, filling the airwaves with political ads many viewers dislike. Companies running ads immediately afterward have been concerned about the potential of a negative spillover effect on how they and their products and services are perceived.
WASHINGTON--Earth's tropics are expanding poleward and that expansion is driven by human-caused changes to the ocean, according to new research.
The tropics wrap around Earth's middle like a warm, wet belt. This part of the globe gets the most direct sunlight throughout the year and is characterized by high average temperatures and heavy rainfall. In contrast to the tropics' lush interior, however, this region's edges are hot and parched.
Irvine, Calif. - University of California, Irvine materials science researchers are learning about resilience from the mantis shrimp. The ancient crustaceans are armed with two hammerlike raptorial appendages called dactyl clubs that they use to bludgeon and smash their prey. These fists, able to accelerate from the body at over 50 mph, deliver powerful blows yet appear undamaged afterward.
Imagine if every time you looked at a face, one side of the face always appeared distorted as if it were melting, resembling a painting by Salvador Dalí. This is the case for people who have a rare condition known as hemi-prosopometamophosia (hemi-PMO), which makes looking at faces discomforting. According to a new study published in Current Biology, some people with hemi-PMO see distortions to the same half of a person's face regardless of how the face is viewed.
In a new study published in Cell Research, Chen-Yu Zhang's group at Nanjing University School of Life Sciences, China, reports that SIDT1 in the mammalian stomach mediates host uptake of dietary and orally administered microRNAs (miRNAs), thus exerting biological functions in the host.
Most of modern medicine has physical tests or objective techniques to define much of what ails us. Yet, there is currently no blood or genetic test, or impartial procedure that can definitively diagnose a mental illness, and certainly none to distinguish between different psychiatric disorders with similar symptoms. Experts at the University of Tokyo are combining machine learning with brain imaging tools to redefine the standard for diagnosing mental illnesses.
Emerging technologies can be harnessed to use the strengths of hot, humid coastal deserts of the Middle East and North Africa (MENA) region to grow food and other crops.
KAUST researchers are calling for a new generation of vast greenhouse complexes, supported by novel solar panels, air-cooling technologies, and advances in salt-tolerant agriculture. Their concept could kickstart a sustainable agriculture revolution in coastal desert regions across the world.
With the increasing miniaturization of electronic components, researchers are struggling with undesirable side effects: In the case of nanometer-scale transistors made of conventional materials such as silicon, quantum effects occur that impair their functionality. One of these quantum effects, for example, is additional leakage currents, i.e. currents that flow "astray" and not via the conductor provided between the source and drain contacts.
A research team from the University Hospital at Ruhr-Universität Bochum (RUB) has developed a test that provides information on the immune response to the novel coronavirus in patients who need to take immunosuppressive drugs. This is necessary, for instance, following an organ transplantation. "We were able to show that these patients can achieve a good immune response to Sars-Cov-2 despite immunosuppression," says Professor Nina Babel, Head of the Centre for Translational Medicine at Marien Hospital Herne.
