The immune system becomes disordered and dysfunctional with age in numerous different ways. The B cell component accumulates inflammatory and problematic cells that are known as age-associated B cells. Here, researchers show that these errant B cells produce antibodies that provoke autoimmunity. B cell aging is a problem with a […]

The proteasome is a complex structure in the cell that is responsible for breaking down unwanted proteins. Like other recycling processes, proteasomal function is connected to life span in short-lived species. Better cell maintenance in response to stress and damage improves cell function, organ function, and longevity. The proteasome is […]

Electricity may slow – and in some cases, stop – the speed at which breast cancer cells spread through the body, a new study indicates. The research also found that electromagnetic fields might hinder the amount of breast cancer cells that spread. The findings, published recently in the journal Bioelectricity, suggest […]

A new study has found that about 35% of Americans with a cancer history had an elevated risk of cardiovascular disease in the next decade, compared with about 23% of those who didn’t have cancer. Based on a risk calculator that estimates a person’s 10-year chances of developing heart disease or stroke, […]

While the drug tamoxifen reduces the risk of developing breast cancer and prevents recurrence, the side-effects cause many women to discontinue their treatment. A study involving researchers at Karolinska Institutet in Stockholm has now found that a much lower dose than the standard produces a good effect with fewer adverse […]

Using artificial intelligence and mobile digital microscopy, researchers hope to create screening tools that can detect precursors to cervical cancer in women in resource-limited settings.

More than 37 million people in the United States have chronic kidney disease, the result of ever-increasing rates of common health conditions such as diabetes and high blood pressure. Normal kidneys work relentlessly to maintain a crucial balance of fluids inside our bodies. They also filter sodium, other minerals and […]

A long noncoding RNA whose function was previously unknown turns out to play a vital role in mobilizing the immune response following a bone marrow transplant or solid organ transplantation. This RNA molecule, catalogued in scientific databases simply as Linc00402, helps activate immune defenders known as T cells in response […]

Prebiotics are an intriguing potential approach to curbing some of the severe side effects that life-saving immunotherapy treatments can wreak on the gut, according to an analysis of recent studies and clinical trials by researchers at the University of Michigan Rogel Cancer Center. Rather than trying to introduce beneficial strains of […]

A team of researchers from the University of Michigan and the Henry Ford Health System is shedding new light on important differences in triple-negative breast cancer tumours from African, African American and white patients. The work was conducted using mouse xenograft models implanted with patient breast tumours. The findings, which […]

A major challenge in the study of aging and age-related disease is establishing the direction of causation. A great many mechanisms of aging are known, but it is difficult to firmly establish the relationships between them. The body is made up of many interacting systems, and changes in any one […]

A new study from the Maurice and Gabriela Goldschleger School of Dental Medicine at Tel Aviv University (TAU) has found that the excessive use of smartphones and social media can lead to problems sleeping; drowsiness and fatigue during the day; teeth-grinding; and pain in the mouth muscles and jaws. The researchers compared about 600 […]

A study of Japanese university students and recent graduates has revealed that writing on physical paper can lead to more brain activity when remembering the information an hour later. Researchers say that the unique, complex, spatial and tactile information associated with writing by hand on physical paper is likely what […]

A groundbreaking new study led by University of Minnesota Twin Cities researchers from both the College of Science and Engineering and the Medical School shows for the first time that lab-created heart valves implanted in young lambs for a year were capable of growth within the recipient. The valves also […]

Have you forgotten where you laid your keys?  Ever wondered where you had parked your car? Or having trouble remembering the name of the new neighbor? Unfortunately, these things seem to get worse as one gets older. A big question for researchers is where does benign forgetfulness end and true […]

In a recent study testing the effects of exercise on overall metabolism, researchers at Oregon State University found that even a single session of moderate aerobic exercise makes a difference in the cells of otherwise sedentary people. Mitochondria are the part of the cell responsible for the biological process of […]

In researching the causes and potential treatments for degenerative conditions such as Alzheimer’s or Parkinson’s disease, neuroscientists frequently struggle to accurately identify cells needed to understand brain activity that gives rise to behaviour changes such as declining memory or impaired balance and tremors. A multidisciplinary team of the Georgia Institute […]

The small intestine is ground zero for survival of animals. It is responsible for absorbing the nutrients crucial to life and it wards off toxic chemicals and life-threatening bacteria. In a new study published in the journal Science, Yale researchers report the critical role played by the gut’s immune system […]

New insights into a little-understood DNA structure could provide the basis for new cancer therapies. DNA is usually depicted as double-stranded, but not much is known about parts of the genome that adopt four-stranded structures known as quadruplexes. UC Riverside researchers have discovered that they play a key role in […]

Researchers here note an association between vision impairment and mortality in later life. This has the look of a correlation that exists because aging is a global process at work throughout the body. It stems from the accumulation of a few classes of cell and tissue damage. That damage causes […]

University of Manchester scientists have discovered previously unseen blood biomarkers which could one day be used to test for Alzheimer’s disease, years before its symptoms appear. The ground-breaking study, published in ACS Nano, used cutting-edge nanotechnology uniquely developed and patented by the Nanomedicine Lab in Manchester, to extract blood signals of […]

In the past few years, several medications have been found to be contaminated with NDMA, a probable carcinogen. This chemical, which has also been found at Superfund sites and in some cases has spread to drinking water supplies, causes DNA damage that can lead to cancer. MIT researchers have now […]

TARM1 is a receptor protein whose role in the functioning of the immune system is unknown. In a new study, scientists from Japan have explored the potential role of TARM1 in the pathogenesis of rheumatoid arthritis by analyzing mouse models. They found that TARM1 activated dendritic cells, and the development of […]

CytoSeek’s technology is designed to help target the immune cells to the solid tumour and improve their cancer cell-killing ability. Solid tumours account for the majority of deaths from cancer and are notoriously difficult to treat, even with existing immune cell therapies, because the tumour suppresses immune cells’ ability to […]

It has long been understood that a parent’s DNA is the principal determinant of health and disease in offspring. Yet inheritance via DNA is only part of the story; a father’s lifestyle such as diet, being overweight and stress levels have been linked to health consequences for his offspring. This […]

More than 1,200 people with rare diseases have received a diagnosis thanks to the integration of large-scale genomics into the Stockholm region’s healthcare system. This is according to a study from Karolinska Institutet in Sweden that analysed the result of the first five years of collaboration on whole-genome sequencing between […]

The vast majority of people infected with SARS-CoV-2 clear the virus, but those with compromised immunity—such as individuals receiving immune-suppressive drugs for autoimmune diseases—can become chronically infected. As a result, their weakened immune defenses continue to attack the virus without being able to eradicate it fully. This physiological tug-of-war between […]

The ears don't just help you hear. They also help a person walk, stand, and stay balanced. In fact, they work together with other systems in the body to help one understand our place in space. Many people who have sensations of vertigo find that the problem lies in their […]

Even though a fruit fly doesn’t have ears, it can hear with its antennae. In a study published in the journal Development, USC Stem Cell scientists describe how adult flies can regenerate sensory hearing cells in their antennae, and how studying flies can provide a new way to understand and […]
