In the most comprehensive analysis to date of U.S. children tested and treated for COVID-19, an organization representing seven of the nation's largest pediatric medical centers reports that some groups of children are faring significantly worse than children in general during the pandemic.
The savanna tree frog Bokermannohyla ibitiguara is about 4 cm long and is found only in gallery forest along streams in the Serra da Canastra mountain range in the state of Minas Gerais, Southeast Brazil. In this watery forest environment, it can grow, feed, mate, and lay eggs without needing to range very far throughout its life cycle, according to a study published in Diversity and Distributions.
Deep neural networks, multilayered systems built to process images and other data through the use of mathematical modeling, are a cornerstone of artificial intelligence.
They are capable of seemingly sophisticated results, but they can also be fooled in ways that range from relatively harmless - misidentifying one animal as another - to potentially deadly if the network guiding a self-driving car misinterprets a stop sign as one indicating it is safe to proceed.
While respiratory issues continue to be the most common symptom of a COVID-19 infection, new research indicates the disease could also be associated with hypercoagulability, or increased tendency of the blood to clot. In a new study published November 20, 2020 in the journal EClinical Medicine by The Lancet, researchers from UC San Diego Health found that blood clots led to an increased risk of death by 74 percent.
The spiral-shaped disc of stars and planets is being pulled, twisted and deformed with extreme violence by the gravitational force of a smaller galaxy - the Large Magellanic Cloud (LMC).
Scientists believe the LMC crossed the Milky Way's boundary around 700 million years ago - recent by cosmological standards - and due to its large dark matter content it strongly upset our galaxy's fabric and motion as it fell in.
The effects are still being witnessed today and should force a revision of how our galaxy evolved, astronomers say.
Changes in climate can increase infectious disease risk in animals, researchers found -- with the possibility that these diseases could spread to humans, they warn.
The insulation around nerve cell components in our corneas have unique properties, and little is known about them. But UConn School of Medicine neuroscience professor Royce Mohan believes his lab is on the verge of uncovering a path to better understanding that ultimately could lead to several vision-preserving advances.
Physicians and scientists are constantly on the lookout for new disease genes that can help them understand why patients have undiagnosed medical problems. Often the first clues come from genetic testing that reveals a change or mutation in a gene that they see in a child but not their parents. This is exactly what led to a new study published today in the American Journal of Human Genetics.
VIRTUAL MEETING (CST), November 22, 2020 -- The rapid spread of COVID-19 overwhelmed hospitals that were unable to contend with the increasing number of patients, many requiring ventilators and other critical care. Such conditions can put medical workers at risk. Now researchers are studying methods to increase hospital safety and efficacy during the pandemic.
A shortage of life-saving ventilators, which typically cost around $30,000 each, hit hospitals particularly hard.
VIRTUAL MEETING (CST), November 22, 2020 -- Mechanical engineer Roberto Zenit spent the summer of 2019 trying to solve a problem that now plagues science departments around the world: How can hands-on fluid dynamics experiments, usually carried out in well-stocked lab rooms, be moved off campus? Since the pandemic hit, leading researchers like Zenit have found creative ways for students to explore flow at home.
VIRTUAL MEETING (CST), November 22, 2020 --They burst out of toilet bubbles, swim across drinking water, spread through coughs. Tiny infectious microbes--from the virus that causes COVID-19 to waterborne bacteria--kill millions of people around the world each year. Now engineers are studying how zinc oxide surfaces and natural hydrodynamic churning have the power to kill pathogens first.
Engineering a spaceship is as difficult as it sounds. Modeling plays a large role in the time and effort it takes to create spaceships and other complex engineering systems. It requires extensive physics calculations, sifting through a multitude of different models and tribal knowledge to determine singular parts of a system's design.
Faster, smaller, smarter and more energy-efficient chips for everything from consumer electronics to big data to brain-inspired computing could soon be on the way after engineers at The University of Texas at Austin created the smallest memory device yet. And in the process, they figured out the physics dynamic that unlocks dense memory storage capabilities for these tiny devices.
A gene known for helping facilitate communication between neurons in the nervous system has been discovered to be connected with Alzheimer's dementia and cognitive decline, according to a national research team led by The Jackson Laboratory and University of Maine.
ITHACA, N.Y. - A multi-institution team co-led by a Cornell University researcher has identified the genetic mechanisms that enable the production of a deadly toxin called Victorin - the causal agent for Victoria blight of oats, a disease that wiped out oat crops in the U.S. in the 1940s.
Victoria blight is caused by the fungus Cochliobolus victoriae, which produces the Victorin toxin, but until now no one has uncovered the genes and mechanisms involved.
