A team at the University of California San Diego has developed a wearable, non invasive Vitamin C sensor that could provide a new, highly personalized option for users to track their daily nutritional intake and dietary adherence. The study was published in the May 18, 2020 issue of ACS Sensors.
Fires are one of the greatest threats to forest heritage. According to data from the Ministry of Agriculture, on average more than 17,000 fires occur per year in Spain, affecting 113,000 hectares and causing enormous financial and scenic losses.
Boston, Mass. - With nearly 5 million confirmed cases globally and more than 300,000 deaths from COVID-19, much remains unknown about SARS-CoV-2, the virus that causes the disease. Two critical questions are whether vaccines will prevent infection with COVID-19, and whether individuals who have recovered from COVID-19 are protected against re-exposure. A pair of new studies led by researchers at Beth Israel Deaconess Medical Center (BIDMC) sheds new light on these questions. Both studies were published today in the journal Science.
Retina is the only part of the central nervous system (CNS) that can be visualized noninvasively with optical imaging approaches. Direct retinal imaging plays an important role not only in understanding diseased eye and ocular therapeutic discovery, but also study of a variety of well-defined CNS disorders.
Climate scientists from the IBS Center for Climate Physics discover that, contrary to previously held beliefs, Neanderthal extinction was neither caused by abrupt glacial climate shifts, nor by interbreeding with Homo sapiens. According to new supercomputer model simulations, only competition between Neanderthals and Homo sapiens can explain the rapid demise of Neanderthals around 43 to 38 thousand years ago.
Australia has often been unfairly portrayed as an old and idle continent with little geological activity, but new research suggests that we remain geologically active and that some of our mountains are still growing.
The University of Melbourne study reveals that parts of the Eastern Highlands of Victoria, including popular skiing destinations such as Mt Baw Baw and Mt Buller, may be as young as five million years, not 90 million years as originally thought.
Living cells inside the body could be placed under surveillance--their location and migration noninvasively tracked in real time over many days--using a new method developed by researchers at KAUST.
The technique uses magnetic core-shell iron nanowires as nontoxic contrast agents, which can be implanted into live cells, lighting up those cells' location inside a living organism when scanned by magnetic resonance imaging (MRI). The technique could have applications ranging from studying and treating cancer to tracking live-cell medical treatments, such as stem cell therapies.
As the world looks to tighten up the illegal capture of wildlife, migratory birds are being threatened by widespread and unsustainable hunting across the Asia-Pacific region.
University of Queensland-led research has revealed that three quarters of migratory shorebird species in the region have been hunted since the 1970s.
UQ PhD student Eduardo Gallo-Cajiao said the finding was deeply concerning, as these globetrotters were already under pressure from other human impacts.
Millions of the world's poorest children are leaving school without mastering even basic levels of reading or maths because of an overlooked pattern of widespread, wealth-based inequalities in their countries' education systems, new research suggests.
The University of Cambridge-led study shows that children from the very poorest families, in what are already some of the lowest-income countries in the world, consistently perform worse in basic literacy and numeracy tests than those from more affluent backgrounds.
UPTON, NY--Scientists have discovered that the transport of electronic charge in a metallic superconductor containing strontium, ruthenium, and oxygen breaks the rotational symmetry of the underlying crystal lattice. The strontium ruthenate crystal has fourfold rotational symmetry like a square, meaning that it looks identical when turned by 90 degrees (four times to equal a complete 360-degree rotation). However, the electrical resistivity has twofold (180-degree) rotational symmetry like a rectangle.
