HOUSTON -- (July 22, 2021) -- Researchers who want bacteria to feel right at home in the laboratory have put out a new welcome mat.
Rice University bioengineers and Baylor College of Medicine scientists looking for a better way to mimic intestinal infections that cause diarrhea and other diseases have built and tested a set of hydrogel-based platforms to see if they could make both transplanted cells and bacteria comfy.
Many people find it morally impermissible to put kidneys, children, or doctorates on the free market. But what makes a market transaction morally repugnant in the eyes of the public? And which transactions trigger the strongest collective disapproval? Researchers from the Max Planck Institute for Human Development and the Robert Koch Institute have addressed these questions. Their findings, published in Cognition, offer new entry points for policy interventions.
ITHACA, N.Y. - A new method that analyzes how individual immune cells react to the bacteria that cause tuberculosis could pave the way for new vaccine strategies against this deadly disease, and provide insights into fighting other infectious diseases around the world.
The cutting-edge technologies were developed in the lab of Dr. David Russell, the William Kaplan Professor of Infection Biology in the Department of Microbiology and Immunology in the College of Veterinary Medicine, and detailed in new research published in the Journal of Experimental Medicine on July 22.
The rapid spread of the Alpha variant of COVID-19 resulted from biological changes in the virus and was enhanced by large numbers of infected people 'exporting' the variant to multiple parts of the UK, in what the researchers call a 'super-seeding' event.
Engineers at the University of California San Diego developed a soft and stretchy ultrasound patch that can be worn on the skin to monitor blood flow through major arteries and veins deep inside a person's body.
Knowing how fast and how much blood flows through a patient's blood vessels is important because it can help clinicians diagnose various cardiovascular conditions, including blood clots; heart valve problems; poor circulation in the limbs; or blockages in the arteries that could lead to strokes or heart attacks.
The University of Surrey has built an artificial intelligence (AI) model that identifies chemical compounds that promote healthy ageing - paving the way towards pharmaceutical innovations that extend a person's lifespan.
As a fourth-generation cattle farmer, Jared Decker knows that cattle suffer from health and productivity issues when they are taken from one environment -- which the herd has spent generations adapting to -- to a place with a different climate, a different elevation or even different grass. But as a researcher at the University of Missouri, Decker also sees an opportunity to use science to solve this problem, both to improve the welfare of cattle and to plug a leak in a nearly $50 billion industry in the U.S.
Having friends may not only be good for the health of your social life, but also for your actual health--if you're a hyena, that is. Strong social connections and greater maternal care early in life can influence molecular markers related to gene expression in DNA and future stress response, suggests a new University of Colorado Boulder study of spotted hyenas in the wild.
Most people can expect to break close to two bones in their lifetime, but those with osteogenesis imperfecta -- also known as brittle bone disease -- can break hundreds of bones before they even hit puberty. And while healthy bones can break from a hard fall or a bad car wreck, there may not be an apparent reason at all with brittle bone disease.
DURHAM, N.C. - Scientists at Duke University have developed a suite of four new tests that can be used to detect coal ash contamination in soil with unprecedented sensitivity.
The tests are specifically designed to analyze soil for the presence of fly ash particles so small other tests might miss them.
New University of Otago research has been examining how alpine-based hedgehogs hibernate from a different perspective - their backs.
Dr Nick Foster from the Department of Zoology has been involved with the Te Manahuna Aoraki project and has been attaching small transmitting 'backpacks' onto hedgehogs in the Mackenzie Basin's alpine zones. The mammals are considered pests in New Zealand for the damage they cause to native insects and wildlife throughout the country.
The future of Samoa's electricity system could go green, a University of Otago study has shown.
Pacific Island nations are particularly susceptible to climate change and face high costs and energy security issues from imported fossil fuels.
For these reasons many Pacific Island nations have developed ambitious 100 per cent renewable energy targets. However, they have not been subject to rigorous peer-reviewed studies to help develop these targets and pathways for achieving them in the same way as more developed countries.
Cambridge, MA ¬- Astronomers at the Center for Astrophysics | Harvard & Smithsonian have helped detect the clear presence of a moon-forming region around an exoplanet -- a planet outside of our Solar System. The new observations, published Thursday in The Astrophysical Journal Letters, may shed light on how moons and planets form in young stellar systems.
Adults and children with COVID-19 who have a history of malnutrition may have an increased likelihood of death and the need for mechanical ventilation, according to a study published in Scientific Reports.
Malnutrition hampers the proper functioning of the immune system and is known to increase the risk of severe infections for other viruses, but the potential long-term effects of malnutrition on COVID-19 outcomes are less clear.
