Study reveals potential target for treatment of diseases associated with mitochondrial DNA mutations
https://www.eurekalert.org/news-releases/954172

May 27th, 2022 - A study by Brazilian scientists points to the probable biological mechanism that modulates the accumulation of mutant mitochondrial DNA in cells during aging, especially in the liver. The mechanism is called autophagy, a process of cellular cleansing that destroys organelles, including mitochondria, and recycles their components. The findings resolve a paradigm in the field and raise a hypothes...

Social media data show language related to depression didn’t spike after initial pandemic wave
https://www.eurekalert.org/news-releases/954190

May 27th, 2022 - Researchers who analyzed language related to depression on social media during the pandemic say the data suggest people learned to cope as the waves wore on. University of Alberta researcher Alona Fyshe and her collaborators at the University of Western Ontario hypothesized that depression-related language would spike during each wave of COVID-19. But their study shows that wasn’t the case. “Th...

Comparing cancer-related spending, mortality rates in high-income countries
https://www.eurekalert.org/news-releases/953997

May 27th, 2022 - About The Study: Researchers found in this study of 22 high-income countries that cancer care spending in 2020 was not associated with age-standardized cancer mortality rates, and that although the United States spent more on cancer care than any other country, this expenditure was not associated with substantially lower cancer mortality rates. Authors: Cary P. Gross, M.D., of the Yale School o...
