Hurricane Teddy has transitioned to a large post-tropical cyclone over eastern Canada. Using a NASA satellite rainfall product that incorporates data from satellites and observations, NASA estimated Teddy's rainfall rates. In addition to the heavy rainfall, Teddy causing destructive waves and strong winds today, Sept. 23, for portions of Atlantic Canada.
Teddy made landfall in the Sheet Harbour area of Nova Scotia on the province's Eastern Shore around 7:30 a.m. EDT, Sept. 23.
Warnings and Watches in Effect on Sept. 23
Skoltech researchers have designed and developed an interface that allows a user to direct a small drone to light-paint patterns or letters through hand gestures. The new interface, DroneLight, can be used in distant communications, entertainment, and even search and rescue: https://youtu.be/SdnIqLjtGeU. The paper was published on the preprint server arXiv.org and presented at IEEE International Conference on Robot & Human Interactive Communication (IEEE RO_MAN 2020).
NASA's Terra satellite provided a visible image of a slightly elongated Tropical Storm Dolphin as it battled wind shear upon its approach to east central Japan.
A Visible Satellite Image
The Moderate Resolution Imaging Spectroradiometer or MODIS instrument that flies aboard NASA's Terra satellite captured a visible image of Tropical Storm Dolphin on Sept. 23 at 12:30 a.m. EDT (0430 UTC). Dolphin appeared somewhat elongated from west to east likely from the strong vertical wind shear the storm has been battling.
According to the World Health Organization, more than a billion people, that is, about 15% of the world's population, have various forms of disability. Every year, up to half a million people receive spinal cord injuries, which are often accompanied by paralysis, and disorders of autonomic functions. To find ways to restore health to people with disabilities, researchers are developing invasive neuroprostheses that can transmit electrical signals to the spinal cord and brain and recover lost functions.
Recent work published by researchers at the University of Kentucky's Sanders-Brown Center on Aging (SBCoA) highlights what the lead investigator calls the "cornerstone" of her lab. Maj-Linda Selenica, assistant professor at SBCoA, led the study recently published in BBA Molecular Basis of Disease. She says their approach was unconventional as it looked at the molecular mechanisms implicated in TDP-43 biology, which is the focus of her lab.
Slow-moving post-tropical storm Beta continues to drop large amounts of rainfall in Texas as it moves into the Lower Mississippi Valley on Sept. 23. A NASA satellite rainfall product that incorporates data from satellites and observations estimated Beta's rainfall rates.
Flash Flood Watches in Effect on Sept. 23
NOAA's National Weather Service issued warnings and watches for Beta on Sept. 23. There are Flash Flood Watches currently in effect across southeast Texas and southern Louisiana.
What is a Post-tropical Cyclone?
NASA's Terra satellite passed over post-tropical storm Paulette after it had transitioned for a second time. Using infrared imagery, Terra found no strong storms remained.
Got a cat that always seems hungry? New University of Guelph research suggests you might want to reduce -- not increase -- how often you feed them.
Animal nutrition specialists in U of G's Ontario Veterinary College (OVC) and Ontario Agricultural College (OAC) have found that feeding cats one large meal a day may help control hunger better than feeding them several times a day.
The research, published in the journal PLOS One, revealed that cats that ate one meal a day were more satisfied, which could result in less food-begging behaviour.
PULLMAN, Wash. - Researchers at Washington State University have predicted how and where the Asian giant hornet, an invasive newcomer to the Pacific Northwest, popularly dubbed the "murder hornet," could spread and find ideal habitat, both in the United States and globally.
Sharing their discoveries in a newly published article in the Proceedings of the National Academy of Sciences, the team found that if the world's largest hornet gains a foothold in Washington state, it could spread down much of the west coast of the United States.
PHILADELPHIA - Exposure to hydraulic fracturing fluid in drinking water has been shown to increase the risk of respiratory problems, premature births, congenital heart defects, and other medical problems. But not all wells are created equal. Since different hydraulic fracturing -- or fracking -- sites use a diverse mix of chemical ingredients, often individuals and researchers are in the dark about the health consequences of living near a particular well.
A vast amount of data is booming generated every single day in this information era, which triggered the development of new highspeed wireless data communication technologies, such as the fifth generation of cellular systems (5G) and the light-fidelity (LiFi). This, combined with the emerging fields of 'Internet of Things' (IoT) and big data, persistently pushing the miniaturization and densification of wireless communication terminals.
Maturation of the ribosome is a complex operation. Work by an Ludwig-Maximilians-Universitaet (LMU) in Munich team now shows that the 90S precursor of the small 40S subunit undergoes a 'molting' process, during which it progressively discards its outermost components.
Colorectal cancer constitute the third most common cancer in the Western world. Their incidence constantly increases as the population ages, and despite recent advances in colorectal cancer therapy, the cancer metastasizes in every third of colorectal cancer patients, and a significant part of these patients eventually die from the disease.
An analysis of genetic data collected from more than 850,000 individuals of European ancestry has found a link between obesity-related genes and rheumatoid arthritis.
In the Arthritis & Rheumatology analysis, investigators found an increased risk of rheumatoid arthritis when body mass index was predicted to be high based on an individual's genetics. This was observed for both men and women.
As the antimalarial drugs hydroxychloroquine and chloroquine have drawn attention as potential therapies for COVID-19 and are being widely used off-label, it's now more important than ever to have a thorough assessment of the safety of these medications. A recent analysis published in the British Journal of Clinical Pharmacology provides new insights.
