New research suggests diabetes drug could slow Alzheimer’s progression

Posted on August 16, 2021 by Rich Haridy

The research found a link between slower cognitive decline and diabetic patients taking drugs called gliptins

A new study published in the journal Neurology is reporting an association between a particular class of drugs used to treat type 2 diabetes and decreased Alzheimer’s disease biomarkers. It is unclear exactly how these diabetes drugs could exert neuroprotective effects, but Alzheimer’s experts are calling for large-scale clinical trials to explore these potential treatments in non-diabetic groups.

Type 1 diabetes prevented in mice by immune-cell-regulating peptide

Posted on August 16, 2021 by Michael Irving

A peptide called MOTS-c has shown promise in preventing type 1 diabetes, according to new tests in human cells in culture and live mice. The peptide seems to regulate the immune system, potentially leading to treatments for type 1 diabetes and other au… Continue reading Type 1 diabetes prevented in mice by immune-cell-regulating peptide→

Can Alzheimer’s be tackled by cutting cholesterol in the brain?

Posted on August 16, 2021 by Nick Lavars

Scientists have uncovered a mechanism that may allow Alzheimer's to be tackled by controlling cholesterol levels in the brain

One interesting area of Alzheimer’s research focuses on the relationship between cholesterol in the brain and onset of the disease, with studies suggesting the compound can greatly accelerate the buildup of troublesome brain plaques. A new study has expanded our knowledge of this phenomenon by observing it in action in live mice, with the scientists even finding they could intervene in cholesterol production to make the plaques all but disappear.

Life story of one mammoth traced from birth to death, week by week

Posted on August 13, 2021 by Michael Irving

Scientists have been able to track the entire life of a mammoth that lived more than 17,000 years ago, right down to the week. By studying the isotopes in different parts of its tusk, the team figured out where in Alaska it likely was at any given poin… Continue reading Life story of one mammoth traced from birth to death, week by week→

Report slams “blue hydrogen” as worse for the climate than gas or coal

Posted on August 13, 2021 by Loz Blain

The hydrogen industry is gearing up to play an important role in the global transition to clean energy – particularly in hard-to-abate sectors like aviation and steel production. As it grows, you’re going to start hearing more about colors. Black hydro… Continue reading Report slams “blue hydrogen” as worse for the climate than gas or coal→

AI analyzes gray matter loss to predict the onset of Alzheimer’s

Posted on August 13, 2021 by Nick Lavars

Scientists have developed a new machine learning algorithm that analyzes gray matter density in the brain as a potential biomarker for Alzheimer's

Advances in artificial intelligence promise to open up all sorts of possibilities when it comes to health care, and analyzing medical images for signs of trouble is already proving to be a great strength of the technology. Scientists at Cambridge University have demonstrated a new type of machine learning algorithm they say can detect structural changes in the brain that are indicative of early dementia, and can be combined with standard memory tests to calculate the likelihood of someone going on to develop Alzheimer’s.

Landmark study finds surprising timing of life’s metabolic highs and lows

Posted on August 13, 2021 by Rich Haridy

Putting a little bit of weight on in middle age has often been waved away as a result of slowing metabolism. “I’m not burning those calories as quickly as I did when I was younger,” people often say. But a landmark new study tracking energy expenditure… Continue reading Landmark study finds surprising timing of life’s metabolic highs and lows→
