Which photophysical properties does carbyne have? This was the subject of research carried out by scientists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), the University of Alberta, Canada, and the Ecole Polytechnique Fédérale de Lausanne in Switzerland, which has led to a greater understanding of the properties of this unusual form of carbon. Their findings have now been published in the latest edition of the journal Nature Communications.
Across America, hazardous waste sites pose an ongoing threat to human and environmental health. The most severe cases are known as Superfund sites, of which over a thousand currently exist. Some 50 million Americans live within three miles of one of these zones, potentially placing them at increased risk for cancer and other serious diseases.
Philadelphia, November 17, 2020 - Scientists from Northwell Health Laboratories have developed a new diagnostic multiplex assay that can be used for epidemiological surveillance and clinical management of COVID-19. The Northwell Health Laboratories laboratory-developed test (NWHL LDT) uses a different set of reagents than current assays and can test 91 patients at a time for SARS-CoV-2, versus a maximum of 29 patients using the modified Centers for Disease Control and Prevention (CDC) assay.

The largest collection of public internet censorship data ever compiled shows that even citizens of what are considered the world's freest countries aren't safe from internet censorship.
Over the last few decades, conventional electronics has been rapidly reaching its technical limits in computing and information technology, calling for innovative devices that go beyond the mere manipulation of electron current. In this regard, spintronics, the study of devices that exploit the "spin" of electrons to perform functions, is one of the hottest areas in applied physics. But, measuring, altering, and, in general, working with this fundamental quantum property is no mean feat.
When a patient with cancer is told the devastating news that their disease has spread, or metastasized, to a new part of their body, it has most often moved to their lungs. The branching blood vessels that allow oxygen to diffuse from the lungs' air sacs into red blood cells are so tiny that a rogue cancer cell circulating in the bloodstream can easily get stuck there and take up residence, eventually growing into a secondary tumor. Once established, metastatic tumors unleash a campaign of chemical cues that thwart the body's defenses, hampering efforts to induce an immune response.
Though Alzheimer's disease (AD) is a common and fatal neurodegenerative brain disorder, most of AD treatments seem to not be making much headway to unravel the mystery of its cause. Many AD drugs have targeted the elimination of beta-amyloid (Aβ) or amyloid plaques, which block cell-to-cell signaling at synapses. But some AD patients continue to show neurodegeneration and cognitive decline even after the removal of the amyloid plaques. Conversely, many people indicate no signs of neurodegeneration and cognitive impairment even in very high level of Aβ.
The impact of the coronavirus pandemic has created concerns amongst the scientific research community that funding to their area will be impacted in the long term, a global survey shows. Half (47%)?of those surveyed believe less funding will be available in their area in the future because of COVID-19, signaling a potentially lasting impact on the scientific research landscape. Just one in 10 (9%) said they expected an increase.
A remote monitoring tool to help authorities manage public safety and environmental issues in recently abandoned coal mines has been developed by the University of Nottingham.
The tool uses satellite radar imagery to capture millimetre-scale measurements of changes in terrain height. Such measurements can be used to monitor and forecast groundwater levels and changes in geological conditions deep below the earth's surface in former mining areas.
SEATTLE -- Nov. 16, 2020 -- Results from a new trial published by a team led by researchers at Fred Hutchinson Cancer Research Center suggests lower dairy intake may be beneficial for people with metabolic syndrome. In a new study published in the American Journal of Clinical Nutrition, Dr. Mario Kratz, an associate professor in Fred Hutch's Public Health Sciences Division, led a team that looked at dairy's impact on regulating blood sugar levels in people with metabolic syndrome.
SAN ANTONIO -- Nov. 16, 2020 -- A new study by Southwest Research Institute scientists describes how they have expanded the capabilities of the prototype spaceflight instrument Chemistry Organic and Dating Experiment (CODEX), designed for field-based dating of extraterrestrial materials. CODEX now uses two different dating approaches based on rubidium-strontium and lead-lead geochronology methods. The instrument uses laser ablation resonance ionization mass spectrometry (LARIMS) to obtain dates using these methods.
Physicists from MIPT and Vladimir State University, Russia, have achieved a nearly 90% efficiency converting light energy into surface waves on graphene. They relied on a laser-like energy conversion scheme and collective resonances. The paper came out in Laser & Photonics Reviews.
Cambridge/Jena (16.11.2020) Linkages between organic and inorganic materials are a common phenomenon in nature, e.g., in the construction of bones and skeletal structures. They often enable combinations of properties that could not be achieved with just one type of material. In technological material development, however, these so-called hybrid materials still represent a major challenge today.

WESTMINSTER, Colorado - November 16 2020 - Today the journal Invasive Plant Science and Management (IPSM) announced the launch of a new series focused on the biology and ecology of invasive plants.
A new national survey, looking at how the COVID-19 pandemic has impacted young US adults' loneliness, reveals "significant depressive symptoms" in 80% of participants.
Over 1,000 Americans aged 18-35 took part in the online anonymous questionnaire, which also asked the subjects to report on their anxiety and substance use.
