When blood flow to the brain is somehow reduced or restricted, a person can suffer what we know as a stroke (from "ischemic stroke" in medical jargon). Stroke is one of those conditions that seems fairly common. This isn't a misperception: just in Europe, there are over 1.5 million new cases each year.
Researchers from North Carolina State University have developed a patch that plants can "wear" to monitor continuously for plant diseases or other stresses, such as crop damage or extreme heat.
"We've created a wearable sensor that monitors plant stress and disease in a noninvasive way by measuring the volatile organic compounds (VOCs) emitted by plants," says Qingshan Wei, co-corresponding author of a paper on the work. Wei is an assistant professor of chemical and biomolecular engineering at NC State.
The Hikurangi Margin, located off the east coast of the North Island of New Zealand, is where the Pacific tectonic plate dives underneath the Australian tectonic plate, in what scientists call a subduction zone. This interface of tectonic plates is partly responsible for the more than 15,000 earthquakes the region experiences each year. Most are too small to be noticed, but between 150 and 200 are large enough to be felt. Geological evidence suggests that large earthquakes happened in the southern part of the margin before human record-keeping began.
In a new study on mice, Johns Hopkins Medicine researchers report that using MRI scans to measure blood volume in the brain can serve as a noninvasive way to potentially track the progress of gene editing therapies for early-stage Huntington's disease, a neurodegenerative disorder that attacks brain cells. The researchers say that by identifying and treating the mutation known to cause Huntington's disease with this type of gene therapy, before a patient starts showing symptoms, it may slow progression of the disease.
Hamilton, ON (July 7, 2021) - A McMaster University team of researchers recently discovered how, exactly, the COVID-19 vaccines that use adenovirus vectors trigger a rare but sometimes fatal blood clotting reaction called vaccine-induced immune thrombotic thrombocytopenia or VITT.
The findings will put scientists on the path of finding a way to better diagnose and treat VITT, possibly prevent it and potentially make vaccines safer.
A genetic map of an aggressive childhood brain tumour called medulloblastoma has helped researchers identify a new generation anti-cancer drug that can be repurposed as an effective treatment for the disease.
This international collaboration, led by researchers from The University of Queensland's (UQ) Diamantina Institute and WEHI in Melbourne, could give parents hope in the fight against the most common and fatal brain cancer in children.
Some exceptionally gifted people have marked human history and culture. Leonardo, Mozart, and Einstein are some famous examples of this phenomenon.
Is talent in a given field a uniquely human phenomenon? We do not know whether gifted bees or elephants exist, just to name a few species, but now there is evidence that talent in a specific field exists, in at least one non-human species: the dog.
As society moves towards a renewable energy future, it's crucial that solar panels convert light into electricity as efficiently as possible. Some state-of-the-art solar cells are close to the theoretical maximum of efficiency--and physicists from the University of Utah and Helmholtz-Zentrum Berlin have figured out a way to make them even better.
Researchers at the IBS Center for Quantum Nanoscience at Ewha Womans University (QNS) have shown that dysprosium atoms resting on a thin insulating layer of magnesium oxide have magnetic stability over days. In a study published in Nature Communications they have proven that these tiny magnets have extreme robustness against fluctuations in magnetic field and temperature and will flip only when they are bombarded with high energy electrons through the STM-tip.
A recent study by scientists from Japanese universities has shown that the shape of cell-derived nanoparticles, known as "extracellular vesicles" (EVs), in body fluids could be a biomarker for identifying types of cancer. In the study, the scientists successfully measured the shape distributions of EVs derived from liver, breast, and colorectal cancer cells, showing that the shape distributions differ from one another. The findings were recently published in the journal Analytical Chemistry.
