Researchers at the University of Waterloo have developed a cheaper and more efficient method for Internet-of-Things devices to receive high-speed wireless connectivity.
With 75 billion Internet of Things (IoT) devices expected to be in place by 2025, a growing strain will be placed on requirements of wireless networks. Contemporary WiFi and cellular networks won't be enough to support the influx of IoT devices, the researchers highlighted in their new study.
Researchers from the University of Surrey have revealed a new ultra-fast method to detect materials that could be used to build explosives. The new detection method is able to analyse a wider range of materials than current thermal based detection systems used in today's airports, while reducing false positive reports.
Visible and infrared imagery from NASA's Terra satellite revealed that strong wind shear was adversely affecting Tropical Depression Erin, located about 200 miles off the Carolina coast.
On Aug. 27, the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Terra satellite provided a visible image of Tropical Depression Erin. In the image, Erin appeared as a swirl of clouds around its center with most of its clouds and thunderstorms pushed southeast of center. Strong northwesterly vertical wind shear was pushing at the storm.
A wireless sensor small enough to be implanted in the blood vessels of the human brain could help clinicians evaluate the healing of aneurysms -- bulges that can cause death or serious injury if they burst. The stretchable sensor, which operates without batteries, would be wrapped around stents or diverters implanted to control blood flow in vessels affected by the aneurysms.
NASA's Terra satellite passed over the northwestern Atlantic Ocean as Dorian reached hurricane status during the afternoon of August 28, 2019.
On Aug. 28, 2019 at 1:30 p.m. EDT, the Moderate Resolution Imaging Spectroradiometer or MODIS instrument aboard NASA's Terra satellite provided a visible image of Dorian near St. Thomas and the U.S. Virgin Islands. At 2 p.m. EDT, the National Hurricane Center noted, "Satellite and radar images indicate that the cloud pattern has become better organized during the past several hours."
Jellyfish are about 95% water, making them some of the most diaphanous, delicate animals on the planet. But the remaining 5% of them have yielded important scientific discoveries, like green fluorescent protein (GFP) that is now used extensively by scientists to study gene expression, and life cycle reversal that could hold the keys to combating aging.
Irvine, Calif. - An international team of Earth system scientists and oceanographers has created the first high-resolution global map of surface ocean phosphate, a key mineral supporting the aquatic food chain. In doing so, the University of California, Irvine-led group learned that marine phytoplankton are a lot more resilient to nutrient stress than previously thought.
Overflowing rivers can cause enormous damage: Worldwide, the annual damage caused by river floods is estimated at over 100 billion dollars - and it continues to rise. So far it has not been clear how climate change influences the magnitude of river floods. There were no apparent patterns.
Pancreatic cancer is one of the most insidious forms of the disease, in which an average of only 9% of patients are alive five years after diagnosis. One of the reasons for such a dismal outcome is that pancreatic cancer cells are able to escape from tumors and enter the bloodstream very early in the disease, meaning that by the time the cancer is discovered, it has usually already spread.
Addis Ababa, Ethiopia (Aug 28) -- Cleveland Museum of Natural History Curator and Case Western Reserve University Adjunct Professor Dr. Yohannes Haile-Selassie and his team of researchers have discovered a "remarkably complete" cranium of a 3.8-million-year-old early human ancestor from the Woranso-Mille paleontological site, located in the Afar region of Ethiopia. Working for the past 15 years at the site, the team discovered the cranium (MRD-VP-1/1), here referred to as "MRD," in February 2016.
OAKLAND, Calif. - Aug. 28, 2019 - Kaiser Permanente has demonstrated promising results in reducing secondary cardiac events and rehospitalizations by creating a virtual cardiac rehabilitation program that fits seamlessly into patients' lives. Increasing rates of program enrollment and completion have been key factors in the improved outcomes. Results and details about the program were published today in NEJM Catalyst.
Menlo Park, Calif. -- Scientists at the Department of Energy's SLAC National Accelerator Laboratory and Stanford University have made the first nickel oxide material that shows clear signs of superconductivity - the ability to transmit electrical current with no loss.
RIVERSIDE, Calif. -- A team led by a psychiatrist at the University of California, Riverside, has tested the orally administered investigational medication ecopipam on adults who stutter in an open-label, uncontrolled clinical trial and found that it reduced their stuttering symptoms from the start of therapy after eight weeks of dosing.
Positive results included increased speech fluency, faster reading completion, and shortened duration of stuttering events.
Two McGill University astronomers have assembled a "fingerprint" for Earth, which could be used to identify a planet beyond our Solar System capable of supporting life.
Researchers from the Moscow Institute of Physics and Technology have created a device that acts like a synapse in the living brain, storing information and gradually forgetting it when not accessed for a long time. Known as a second-order memristor, the new device is based on hafnium oxide and offers prospects for designing analog neurocomputers imitating the way a biological brain learns. The findings are reported in ACS Applied Materials & Interfaces.
