Diabetes Drug Metformin May Protect Aging Brains
WEDNESDAY, Sept. 23, 2020 (HealthDay News) — A common type 2 diabetes drug called metformin may have an unexpected, but positive, side effect: New research suggests that people taking the drug appear to have significantly slower declines in thinking and memory as they age.
“Our six-year study of older Australians with type 2 diabetes has uncovered a link between metformin use and slower cognitive [mental] decline and lower dementia rates,” said study author Dr. Katherine Samaras. She’s the leader of the healthy aging research theme at the Garvan Institute of Medical Research in New South Wales, Australia.
“The findings provide new hope for a means of reducing the risk of dementia in individuals with type 2 diabetes, and potentially those without diabetes,” Samaras said.

Dr. matt kaeberlein researchers aging across species:
Dr. Matt Kaeberlein, is Professor of Pathology, Adjunct Professor of Genome Sciences, and Adjunct Professor of Oral Health Sciences at the University of Washington. With a PhD from MIT in Biology, and post-doctoral work in the Department of Genome Sciences, University of Washington, his research interests are focused on basic mechanisms of aging in order to facilitate translational interventions that promote healthspan and improve quality of life.
Dr. Kaeberlein has published nearly 200 papers in top scientific journals and has been recognized by several prestigious awards, including a Breakthroughs in Gerontology Award, an Alzheimer’s Association Young Investigator Award, an Ellison Medical Foundation New Scholar in Aging Award, a Murdock Trust Award, a Pioneer in Aging Award, and the Vincent Cristofalo Rising Star in Aging Research.
Microsoft AI boasts 97% accuracy in detecting software bugs
Software bugs are a tale as old as time — which, in the case of programming, means about 75 years. In 1947, programmer Grace Murray Hopper was working on a Mark II Computer at Harvard University when she noticed a moth that was stuck in the relay, preventing the computer program from running. It was the first “bug”, and countless others have followed since then.
In the history of programming, bugs have ranged from harmless to absolutely catastrophic. In 1986 and 1987, several patients were killed after a Therac-25 radiation therapy device malfunctioned due to an error by an inexperienced programmer, and a software bug might have also triggered one of the largest non-nuclear explosions in history, at a Soviet trans-Siberian gas pipeline.
While events such as this are rare, it’s safe to say that software bugs can do a lot of damage and waste a lot of time (and resources). According to recent analysis, the average programmer produces 70 bugs per 1,000 lines of code, with each bug demanding 30 times more time to fix than it took to write the code in the first place. In the US alone, an estimated $113 billion is spent identifying and fixing code bugs…
Metformin Treatment Linked to Slowed Cognitive Decline
Summary: Metformin, a drug commonly used to treat diabetes, slows cognitive decline and reduces dementia risk in older people with diabetes.

Metformin is the first-line treatment for most cases of type 2 diabetes and one of the most commonly prescribed medications worldwide, with millions of individuals using it to optimise their blood glucose levels.
Scientists identify dozens of genes allowing cancer cells to evade the immune system
Toronto scientists have mapped the genes allowing cancer cells to avoid getting killed by the immune system in a finding that paves the way for the development of immunotherapies that would be effective for larger patient populations and across different tumour types.
“Over the last decade, different forms of immunotherapy have emerged as really potent cancer treatments but the reality is that they only generate durable responses in a fraction of patients and not for all tumour types,” says Jason Moffat, a professor of molecular genetics in the Donnelly Centre for Cellular and Biomolecular Research at the University of Toronto who led the work.
The study also revealed the need for new therapy to take into account the genetic composition of tumours because of mutations in the cancer cells that can potentially make the disease worse in response to treatment, often referred to as cancer resistance mutations.
