Stress ages the immune system faster

June 15, 2022

Immune aging increases a person’s risk of developing diseases such as cancer and cardiovascular disease, as well as increased susceptibility to infection. Researchers from the University of Southern California (USC) have showed that stress plays a crucial part in aging of the immune system in same-age adults, and propose a little-known therapeutic intervention. With aging […]

Scientists identify new prostate cancer tumour type

May 31, 2022

Scientists at Weill Cornell Medicine have identified two new subtypes of prostate cancer. The tumour subtypes can be resistant to hormone therapy, which reduces the levels of androgens (male hormones) like testosterone that the cancer cells depend on to grow – knowing the exact subtype is nevertheless important for successful cancer treatment. Of the four […]

Higher risk of heart disease for people with cognitive impairment

April 22, 2022

A study led by Canadian researchers suggest cognitive function could predict a person’s future risk of heart disease. In assessing the relationship between cognitive function and future cardiovascular events in over 8,700 people – who also had type 2 diabetes, the researchers found that people with the lowest level of cognitive function had a higher […]

Inner ear damage increases risk of falling in Alzheimer’s patients

April 14, 2022

Damage or impairment to the vestibular system in the inner ear – a common cause of dizziness, vertigo, and balance issues – has been found to elevate the risk for falls in patients with Alzheimer’s disease (Alzheimer’s). According to a research team at Johns Hopkins Medicine University School of Medicine (Johns Hopkins), impairment of the […]

Plastics found for the first time in human bloodstream

March 25, 2022

Scientists from Vrije Universiteit (VU) Amsterdam, the Netherlands, have produced evidence of plastic particles being absorbed into the bloodstream, with a novel method involving the use of mass spectrometry. “We have now proven that our bloodstream, our river of life as it were, has plastic in it,” said VU ecotoxicologist Heather Leslie. Discarded plastic waste […]

Gas flares linked to air pollution and premature death

March 2, 2022

Flaring of excess natural gas occurs when oil/gas producers lack the necessary infrastructures to bring it to market. Flaring reduces the direct venting of the powerful greenhouse gas methane into the atmosphere, but also produces harmful particulate matter known as black particulate matter, or soot. Recently environmental engineers at Rice University (Rice) in Houston have […]

Oestrogen levels linked to severity of COVID-19 infection and risk of death in women

February 21, 2022

An observational study based on Swedish public health records has revealed increased levels of the hormone oestrogen plays a protective role in older women, against severe infection and risk of death from COVID-19. Women seem to suffer less from severe COVID-19 than men, according to health data, hypothesised as due to differences in hormone distribution. […]

Simple retinal scan evaluates biological age and predicts risk of death

January 27, 2022

A new observational study found the gap between a person’s chronological age and retinal age was indicative of their risk of death. This led researchers to propose a simple retina scan as a screening tool to indicate whether a person is at risk of early death. The retinal age gap gleaned from an easy retinal […]
