How Ebola virus manages to evade the body"s immune defenses
Researchers have uncovered the complex cellular mechanisms of Ebola virus, which could help explain its severe toll on humans and identify potential pathways to treatment and prevention......»»
ACE-ing protein detection in single cells
Since the 1950s, researchers have used a famous method invented by Wallace Coulter known as "flow cytometry" to characterize different types of immune cells in research studies and in blood samples from human individuals. This has enabled a much deep.....»»
How bacteria attach their cloaks of invisibility to immune defenses
Bacteria have different strategies for protecting themselves. Some bacterial pathogens surround themselves with a shell made of many sugar chains that lie close together, also known as capsular polymers. This protects the bacteria from drying out and.....»»
Highways to health: Bicontinuous structures speed up cell migration
One of the most important but least understood aspects of healing is cell migration, or the process of cells moving from one part of the body to another. "If you are an ambulance out in the woods," says Karen Xu, an M.D/Ph.D. student in Medicine and.....»»
Cow challenge study should help turn tables on H5N1 in dairy herds
Animal challenge studies completed by U.S. Department of Agriculture (USDA) scientists show that infecting dairy cows with the H5N1 virus in a laboratory setting can trigger clinical signs of disease similar to those of naturally infected animals on.....»»
The Bird Flu Threat Keeps Growing
Human cases keep ticking up, are very likely to be underreported, and offer the virus the opportunity to learn how to spread from person to person......»»
New research offers insight on modeling belief dynamics
Researchers who study belief dynamics often use analogies to understand and model the complex cognitive–social systems that underlie why we believe the things we do and how those beliefs can change over time. Ideas can be transmitted like a virus,.....»»
What shapes a virus"s pandemic potential? SARS-CoV-2 relatives yield clues
Two of the closest known relatives to SARS-CoV-2—a pair of bat coronaviruses discovered by researchers in Laos—may transmit poorly in people despite being genetically similar to the COVID-19-causing virus, a new Yale study reveals......»»
Virus that causes COVID-19 is widespread in wildlife, scientists find
SARS-CoV-2, the virus responsible for COVID-19, is widespread among wildlife species, according to Virginia Tech research published July 29, 2024 in Nature Communications. The virus was detected in six common backyard species, and antibodies indicati.....»»
Apple continuing work on ad-supported TV+ plan; in discussions about UK advertising
After hiring a number of advertising executives earlier in the year, Apple is continuing to show signs of an upcoming ad-supported Apple TV+ plan. According to a new report from The Telegraph, Apple has held meetings with a large UK ratings body to d.....»»
Dengue Fever Threatens to Gate-Crash the 2024 Summer Olympics
Measles, bedbugs, and dengue have all been cited as concerns for tourists and athletes at the 2024 Summer Olympics in Paris, with the tropical virus in particular forcing authorities into action......»»
New nanoparticles boost immune system in mice to fight melanoma and breast cancer
Vanderbilt researchers have developed a set of nanoparticles that stimulate the immune system in mice to fight cancer and may eventually do the same in humans......»»
The Highly Infectious FLiRT Variants Behind the Summer Covid Wave
The latest dominant Covid variants have stronger infectiousness than their predecessors and the ability to evade vaccine-induced antibodies......»»
Scientists hijack natural delivery system to send engineered proteins to target cells
Each cell in the body has its own unique delivery system that scientists are working on harnessing to move revolutionary biological drugs—molecules like proteins, RNA and combinations of the two—to specific diseased parts of the body......»»
New rapid method for determining virus infectivity
A new method that can rapidly determine whether a virus is infectious or non-infectious could revolutionize the response to future pandemics......»»
Scientists resolves a long-debated anomaly in how nuclei spin
Atomic nuclei come in different shapes, varying from football-like ("prolate") to pancake-like ("oblate"). Prolate and oblate shapes have different moments of inertia. This is a body's resistance to having its speed of rotation altered by an external.....»»
Discovery of Piezo1"s new signaling mechanism may aid search for better pain and itch treatments
The human body's sense of touch is so important it can be found throughout the body, not just on the skin. Two tiny sensors of touch, Piezo1 and Piezo2, signal the lightest pressures and can be found monitoring the circulatory system, telling the bod.....»»
Scientists uncover fundamental rules for how dengue virus infects its mosquito and human hosts
Mosquito-borne viral infections once confined to tropical regions are spreading. Dengue virus infects up to 400 million people worldwide each year according to World Health Organization estimates, and no available treatments exist for this disease......»»
Working to strengthen Pacific Northwest defenses against wildfires and wildfire smoke
In the summer of 2020, wildfire smoke blanketed the city of Portland, Oregon, leading to a prolonged period of poor air quality and health concerns for residents. Subsequently, in 2021 the city experienced a heat wave with temperatures reaching as hi.....»»
AMD just snatched the performance crown, even with an impaired Ryzen 9 9950X
An early sample of AMD's Ryzen 9 9950X has been tested, and it already manages to beat the Intel Core i9-14900KS......»»
Five people infected as bird flu appears to go from cows to chickens to humans
High temperatures made it hard for workers to use protective gear during culling. Enlarge (credit: Getty | Edwin Remsberg) The highly pathogenic avian influenza H5N1 virus that spilled from wild birds into US dairy cows.....»»
