Glaucoma is a chronic condition that affects cells at the back of the eye. It is the leading cause of irreversible blindness worldwide, and is responsible for 1 in 10 cases of serious sight impairment in the UK.
People with glaucoma, or at risk of developing glaucoma, require lifelong monitoring, including regular eye tests to track the progression of the disease. Currently, these examinations require regular hospital visits (e.g., twice yearly, for life) and use expensive, specialist equipment.
Tokyo, Japan - Researchers from Tokyo Metropolitan University have realized high-throughput production of thin, ordered through-hole membranes of titanium dioxide. Titania layers were grown using anodization on mask-etched titanium before being crystallized. Applying a second anodization, they converted part of the layer back to an amorphous state. The amorphous portion was then selectively dissolved to free the film while leaving the template intact. This paves the way for industrial production of ordered titania membranes for photonics.
VIRTUAL MEETING (CST), November 22, 2020 -- Wear a mask. Stay six feet apart. Avoid large gatherings. As the world awaits a safe and effective vaccine, controlling the COVID-19 pandemic hinges on widespread compliance with these public health guidelines. But as colder weather forces people to spend more time indoors, blocking disease transmission will become more challenging than ever.
VIRTUAL MEETING (CST), November 22, 2020 -- Eric Hester has spent the last three years chasing icebergs. A mathematics graduate student at the University of Sydney in Australia, Hester and researchers at Woods Hole Oceanographic Institution in Massachusetts are studying how the shape of an iceberg shapes the way it melts.
"Ice deforms as it melts," said physical oceanographer Claudia Cenedese, who has worked with Hester on the project. "It makes these very weird shapes, especially on the bottom, like the way the wind shapes a mountain on a longer time scale."
Researchers at the University of Tokyo have identified how the architecture of the cell nucleus can change gene activity in plants. This discovery reveals fundamental knowledge about genome regulation and points towards future methods for potentially manipulating the expression of many genes simultaneously.
Thanks to modern medicine, humans tend to live much longer than before. Unfortunately, this also opens a wider window to develop chronic diseases with late onset, such as neurodegenerative diseases. Despite considerable research being devoted toward developing a cure for diseases like amyotrophic lateral sclerosis, there are currently no effective treatments.
Osaka City University scientists and colleagues in Japan have found a way to control an interaction between quantum dots that could greatly improve charge transport, leading to more efficient solar cells. Their findings were published in the journal Nature Communications.
Nanomaterials engineer DaeGwi Kim led a team of scientists at Osaka City University, RIKEN Center for Emergent Matter Science and Kyoto University to investigate ways to control a property called quantum resonance in layered structures of quantum dots called superlattices.
Leesburg, VA, November 20, 2020--According to an article in ARRS' American Journal of Roentgenology (AJR), although pediatric CT use has decreased for the evaluation of abdominal pain (perhaps due to implementing an ultrasound-first strategy for suspected appendicitis), CT use has continued to increase among adults with abdominal pain in U.S. emergency department (ED) visits.
A team of researchers has amplified 3D graphene's electrical properties by controlling its curvature.
"Our research showed the conservation and the degradation of the ultra-low dissipative transport of Dirac electrons on the 3D curved surface for the first time," said Yoichi Tanabe, leading author of the study.
Graphene is a 2D atomic-layer material, shaped like honeycombs, which possesses excellent electrical, chemical, thermal, and mechanical properties for a wide range of applications such as semiconductors, electrical batteries, and composites.
University of Virginia Cancer Center researchers have identified a gene responsible for the spread of triple-negative breast cancer to other parts of the body - a process called metastasis - and developed a potential way to stop it.
