NASA's Terra satellite passed over the western Gulf of Mexico during the early afternoon of Sept. 17 and captured a visible image of the newly formed Tropical Depression 11.
The eleventh tropical depression developed during the late morning of Sept. 17. Soon afterward it briefly strengthened into a tropical storm and was re-named Imelda. Then Imelda made landfall near Freeport, Texas. A Tropical Storm Warning was in effect from Sargent to Port Bolivar, Texas.
BOSTON (Sept. 18, 2019)--A novel new study suggests that the gut microbiome has a role in mechanisms related to muscle strength in older adults. The work, led by researchers at the Jean Mayer USDA Human Nutrition Research Center on Aging (HNRCA) at Tufts, is available as a pre-proof in advance of print in Experimental Gerontology.
Bottom Line: Uterine prolapse happens when weakened muscles and ligaments no longer provide enough support for the uterus, which then protrudes into or out of the vagina. This randomized clinical trial compared the effectiveness of two surgical methods to treat women: a vaginal hysterectomy to remove the uterus with ligament suspension to support remaining tissue or uterus-sparing suspension techniques, known as hysteropexy. A previous review of trials comparing these techniques didn't find one superior to the other.
WASHINGTON, D.C., September 17, 2019 -- An interdisciplinary team has found a solution to a problem plaguing developmental biology -- long-term cell tracking and manipulation.
Mechanical engineer Adela Ben-Yakar, at the University of Texas at Austin, collaborated with stem cell biologist Joshua Brickman, from the University of Copenhagen in Denmark, to painstakingly develop an automated microfluidic device for the stable imaging of mice embryonic stem cells over a three-day period. They describe the device and its utility in Biomicrofluidics, from AIP Publishing.
WASHINGTON, D.C., September 17, 2019 -- In a kaleidoscope, mirrors are placed at angles to create a visual illusion of multiple, symmetric images from one original object. The number of symmetric axes in the kaleidoscope depends on the number of mirrors and angles inside.
Drawing inspiration from this multiple-axis symmetry, researchers have discovered a new method for creating mirror-symmetric axes in the polarizations of light, which allows for complex manipulations that are useful in optical tools and technologies.
WASHINGTON, D.C., September 17, 2019 -- Scientists in Christine Hendon's and Michal Lipson's research groups at Columbia University, New York, have used a microchip to map the back of the eye for disease diagnosis.
The interference technology, like bat sonar but using light instead of sound waves, used in the microchip has been around for a little while. This is the first time that technical obstacles have been overcome to fabricate a miniature device able to capture high quality images.
New research by astrophysicists at the University of Kent reveals vital clues about the role recycling plays in the formation of life in our universe.
By investigating the different stages in the life journey of stars and gaining new knowledge about their evolutionary cycle, scientists at the Centre for Astrophysics and Planetary Science have discovered more about a crucial stage in the emergence of life in our Universe. Their research reveals for the first time how matter discarded as stars die is recycled to form new stars and planets.
Learning from each other and benefiting from each other: This is the basic idea behind the European Network for Health Technology Assessment (EUnetHTA). The aim of the collaboration is to promote scientific and technical collaboration between European health technology assessment (HTA) agencies across borders. A second aim is to avoid unnecessary duplication of work - not every diagnostic or therapeutic intervention requires a separate HTA report in every country.
Nitrous oxide is a greenhouse gas and ozone depleting substance.
The ability to exploit this gas as a chemical reagent is an attractive prospect, both as an abundant feedstock and means to remediate the detrimental impact it has on the environment.
Researchers at the University of Warwick have prepared transition metal compounds of nitrous oxide that provide a conceptional foundation for its application in new value-added chemical processes.
Hurricane Kiko continued to track west through the Eastern Pacific Ocean when NASA-NOAA's Suomi NPP satellite passed overhead and provided a view of the storm. Satellite imagery revealed an elongated shape, which indicated wind shear was still affecting Kiko.
The Visible Infrared Imaging Radiometer Suite (VIIRS) instrument aboard Suomi NPP provided an infrared image of the storm on Sept. 16 at 6:12 p.m. EDT (2212 UTC). The VIIRS image and microwave satellite imagery indicates that the northeasterly wind shear that was still affecting Kiko.
A new study led by researchers at the Columbia University Mailman School of Public Health in collaboration with that National Institute of Public Health, Mexico, that accounts for folic acid (FA) fortification in staple foods made from wheat and corn, such as bakery bread and tortillas, found that large proportion of women of childbearing age have FA intake below levels recommended by the World Health Organization, potentially raising the risk for neural tube defects in their offspring.
Physicists from the University of Groningen constructed a two-dimensional spin transistor, in which spin currents were generated by an electric current through graphene. A monolayer of a transition metal dichalcogenide (TMD) was placed on top of graphene to induce charge-to-spin conversion in the graphene. This experimental observation was described in the issue of the journal Nano Letters published on 11 September 2019.
NASA's Terra Satellite provided a visible image of Hurricane Humberto when it was off the coast of the Carolinas and slowly moving north. The satellite image revealed that Humberto is a very large storm.
ITHACA, N.Y. - Researchers are using ultrasonic waves to manipulate the viscosity of shear-thickening materials, turning solids to slush - and back again.
The study, "Using Acoustic Perturbations to Dynamically Tune Shear Thickening in Colloidal Suspensions," was published Sept. 17 in Physical Review Letters.
AURORA, Colo. (Sept. 17, 2019) - A research team led by scientists from the Consortium for Fibrosis Research & Translation (CFReT) at the University of Colorado School of Medicine has identified a potential target for treating heart failure related to fibrosis.
