A new study increases knowledge of the genetics behind aortic aneurysm, a disease that can spark life-threatening events like aortic dissections and ruptures.
University of Michigan Health-led researchers compared blood samples from more than 1,300 people who had a thoracic aortic aneurysm with more than 18,000 control samples, in partnership with U-M's Cardiovascular Health Improvement Project and its Michigan Genomics Initiative.
Scientists at Cambridge and Leeds have successfully reversed age-related memory loss in mice and say their discovery could lead to the development of treatments to prevent memory loss in people as they age.
In a study published today in Molecular Psychiatry, the team show that changes in the extracellular matrix of the brain - 'scaffolding' around nerve cells - lead to loss of memory with ageing, but that it is possible to reverse these using genetic treatments.
Over the last few decades, neurodegenerative diseases became one of the top 10 global causes of death. Researchers worldwide are making a strong effort to understand neurodegenerative diseases pathogenesis, which is essential to develop efficient treatments against these incurable diseases. However, our knowledge about the basic molecular mechanisms underlying the pathogenesis of neurodegenerative diseases is still lacking. A team of researchers found out the implication of lysosomes in the spread of Parkinson's disease.
Replication of SARS-CoV-2, the virus responsible for COVID-19, depends on a series of interactions between viral proteins and different cellular partners such as nucleic acids (DNA or RNA). Characterizing these interactions is crucial to elucidate the process of viral replication and identify new drugs for treating COVID-19.
When Alexander Flemming discovered a mould on a culture plate overgrown with bacteria in 1928, he did not expect to find one of the most widely used active substances: penicillin. Accidental discoveries and the identification of active ingredients from traditional remedies, such as the morphine of the opium poppy, have shaped the discovery of new medicines for a long time.
Modern drug discovery - from chance to system
TROY, N.Y. -- An innovative testing platform that more closely mimics what cancer encounters in the body may allow for more precise, personalized therapies by enabling the rapid study of multiple therapeutic combinations against tumor cells. The platform, which uses a three-dimensional environment to more closely mirror a tumor microenvironment, is demonstrated in research published in Communications Biology.
It's a favourite first-order for the day, but while a quick coffee may perk us up, new research from the University of South Australia shows that too much could be dragging us down, especially when it comes to brain health.
In the largest study of its kind, researchers have found that high coffee consumption is associated with smaller total brain volumes and an increased risk of dementia.

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.
