Many approaches shown to slow aging in animal studies involve an increased efficiency of cell maintenance processes such as the ubiquitin-proteasome system and various types of autophagy. Here researchers discuss the improvement of autophagy in order to slow the age-related decline of mitochondrial function. Mitochondria are the power plants of […]

COVID-19 is not the first viral epidemic and it is not going to be the last one either. Humans have always dealt with such issues, but in the future they may become increasingly more common. One reliable way to make your body more resilient to such threats is regular physical […]

A new study of nearly 5 million live births recorded in California from 2001 to 2012 found that babies born to mothers diagnosed with cannabis use disorders at delivery were more likely to experience negative health outcomes, including preterm birth and low birth weight, compared to babies born to mothers […]

In two landmark studies, researchers have used cutting-edge genomic tools to investigate the potential health effects of exposure to ionizing radiation, a known carcinogen, from the 1986 accident at the Chernobyl nuclear power plant in northern Ukraine. One study found no evidence that radiation exposure to parents resulted in new […]

Cancer accounted for nearly 10 million deaths worldwide in 2020, and almost 2 million new cases are expected to be diagnosed this year in the United States alone. Fighting cancer’s many forms is a complex endeavour for doctors and researchers since there is no one-size-fits-all treatment option, but researchers at […]

The immune system is intimately involved in tissue function throughout the body, but particularly so in the brain. The immune system of the brain is distinct from that of the rest of the body, the two separated by the blood-brain barrier, and the immune cells of the brain participate in […]

Patients with atherosclerosis today usually receive preventive treatment only after a heart attack or stroke because diagnostic methods that can identify individuals and atherosclerotic plaques with high risk are lacking. In addition, the choice of treatment, both surgical and medical, is based on large patient studies and the possibilities for […]

The diagnosis of diseases like cancer almost always needs a biopsy – a procedure where a clinician removes a piece of suspect tissue from the body to examine it, typically under a microscope. Many areas of diagnostic medicine, especially cancer management, have seen huge advances in technology, with genetic sequencing, […]

University of Manchester scientists have cast new light on how our skin repairs itself, bringing the possibility of regeneration of the organ a step closer. The study team, funded by the Medical Research Council and Helmut Horten Foundation, showed the activation of specific parts of the DNA leading to better division of human skin cells. […]

New research has uncovered a possible link between vitamin D deficiency and impaired muscle function, which could help older adults better maintain muscle strength as they age. A study led by Dr Andrew Philp from the Garvan Institute of Medical Research, recently published in the Journal of Endocrinology, used experimental models to […]

The gut microbiome is a highly varied collection of microbial populations that acts in symbiosis with the body to process food and provide needed metabolites. With age, there is a detrimental shift in these populations. Those generating useful metabolites, such as butyrate, diminish in number. Those capable of infiltrating tissue, […]

A new study in laboratory rats has discovered a direct link between low oxygen in the womb and impaired memory function in the adult offspring. It also finds that anti-oxidant supplements during pregnancy may protect against this. Low oxygen in the womb – known as chronic fetal hypoxia – is […]
