Taking on Harmful Cells That Contribute to Age-Related Diseases

A Tufts scientist is testing senolytics to counter senescent cells that promote afflictions like arthritis and Parkinson's disease. It’s not the fountain of youth, but a fast-emerging class of drugs could bring us closer to achieving the age-old quest for longer life, better health, and greater vitality. The drugs, called […]

A noninvasive test to detect cancer cells and pinpoint their location

Diagnostic nanoparticles could be used to monitor tumor recurrence after treatment or to perform routine cancer screenings. Most of the tests that doctors use to diagnose cancer — such as mammography, colonoscopy, and CT scans — are based on imaging. More recently, researchers have also developed molecular diagnostics that can […]

Fungi that live in the gut influence health and disease

Bacteria’s role in gut health has received a lot of attention in recent years. But new research led by scientists at the University of Utah Health shows that fungi—another microorganism that lives within us—may be equally important in health and disease. Fungi thrive in the healthy gut, but they can also […]

Chronic Inflammation Negatively Impacts Proteostasis in Aging Tissues

Proteostasis describes the steady state of a cell, maintaining an appropriate balance of various forms of protein machinery in order to enable continued normal function. With advancing age, proteostasis becomes disrupted in numerous complicated ways. This is a downstream outcome of underlying molecular damage, the reactions to that damage, and […]

Getting to the Heart of Genetic Cardiovascular Diseases: How One Penn Researcher is Using Her Expertise to Help Patients Lead More Active Lives

When she isn’t pursuing her favorite heart-pumping activities of running, swimming, or cycling, Sharlene M. Day, MD, a Presidential Associate Professor of Cardiovascular Medicine and director of Translational Research for the Penn Cardiovascular Institute, is focused on the heart in another way; trying to unlock and treat the mysteries of genetic […]

Study reveals extent of brain complications in children hospitalised with COVID-19

Although the risk of a child being admitted to hospital due to COVID-19 is small, a new UK study has found that around 1 in 20 of children hospitalised with COVID-19 develop brain or nerve complications linked to the viral infection. The research, published in The Lancet Child and Adolescent Health and […]

Ferroptosis in Aging

Ferroptosis is a mode of programmed cell death that manages to be both fairly well explored in the broader research community and far less visible than other programmed cell death processes. It was first named and described about a decade ago, though of course researchers have long explored aspects of […]

Highlighting the effectiveness of the COVID-19 vaccines could hold key to converting doubters

The study, led by the University of Bristol and published in the British Journal of Health Psychology, shows the importance of raising awareness of vaccine efficacy, especially if it compares very favourably to another well-established vaccine. The research focused on adults who were unsure about being vaccinated against COVID-19. Those who were […]

A Breakthrough in Photodynamic therapy

An international team led by physics researchers at The University of Texas at Arlington has published a paper in the high-impact journal Bioactive Materials that describes a breakthrough method of photodynamic therapy (PDT), an emerging cancer treatment. Nil Kanatha Pandey, a doctoral student in physics Professor Wei Chen’s lab, is the first […]

Memory-making involves extensive DNA breaking

The urgency to remember a dangerous experience requires the brain to make a series of potentially dangerous moves: Neurons and other brain cells snap open their DNA in numerous locations — more than previously realized, according to a new study — to provide quick access to genetic instructions for the mechanisms […]

Breakthrough into leading cause of blindness

A University of Manchester led a team of scientists has discovered that the most common form of adult blindness is probably caused by a failure of at least one of five proteins to regulate the immune system. The breakthrough could one day herald the development of transformative treatments for developing […]

Using “guilt by association” to classify cells

Biologists are trying to figure out what makes a cell unique in form and function. But they are not certain which components are key to making similar cells behave differently. Cold Spring Harbor Laboratory (CSHL) Associate Professor Jesse Gillis and his lab are tackling this problem with a new statistical method: they […]

Preventing lung cancer’s unwelcome return

When a doctor gives a patient antibiotics for a bacterial infection, they usually require them to finish the entire treatment, even when symptoms go away. This is to ensure the drugs kill off any remaining bacteria. Cold Spring Harbor Laboratory (CSHL) Visiting Scientist Raffaella Sordella investigated a similar problem that occurs in […]

Your Immune System Could Turn COVID-19 Deadly

Hidden autoimmunity may explain how the coronavirus wreaks such widespread and unpredictable harm. One of the enduring mysteries of COVID-19 is why it makes some people deathly sick but gives others only mild symptoms or none at all. We know that age matters, as do race; gender; and pre-existing medical […]
