Dr. David Sinclair: Why We Get Old And Why We Don’t Have To
Want a longer, healthier life? Resolve your arguments by day’s end
A recent study found that when people feel they have resolved an argument, the emotional response associated with that disagreement is significantly reduced and, in some situations, almost entirely erased.
Cannabis legalization and link to increase in fatal collisions
The legalization of recreational cannabis may be associated with an increase in fatal motor vehicle collisions based on data from the United States, and authors discuss the implications for Canada in an analysis in CMAJ (Canadian Medical Association Journal).
Study strengthens links between red meat and heart disease
An observational study in nearly 20,000 individuals has found that a greater intake of red and processed meat is associated with worse heart function.
Mediterranean diet with lean beef may lower risk factors for heart disease
Eating red meat may have a bad reputation for being bad for the heart, but new research found that lean beef may have a place in healthy diets, after all.
New benefits from anti-diabetic drug metformin
Metformin inhibits disease progression in non-diabetic chronic kidney disease (ND-CKD)
Two blood thinners at once: More risk with the same reward
For some patients, adding aspirin to a direct oral anticoagulant is an equation that rarely adds up.
Once-a-week insulin treatment could be game-changing for patients with diabetes
Treating people with Type 2 diabetes with a new once-a-week injectable insulin therapy proved to be safe and as effective as daily insulin injections, according to the results of two international clinical trials. The studies suggest that the once-weekly treatment could provide a convenient alternative to the burden of daily insulin shots for diabetes patients.
Role of physical, mental health in cognitive impairment
A recent study suggests that preserving physical and mental health helps older adults experiencing cognitive impairment stave off declines in cognitive engagement.
Flushing a public toilet? Don’t linger, because aerosolized droplets do
Because COVID-19 has been detected in urine and stool samples, public restrooms can be cause for concern. Researchers measured droplets generated from flushing a toilet and a urinal in a public restroom and found a substantial increase in the measured aerosol levels in the ambient environment with the total number of droplets generated in each flushing test ranging up to the tens of thousands. Due to their small size, these droplets can remain suspended for a long time.
Multivitamins, omega-3, probiotics, vitamin D may lessen the risk of a positive COVID-19 test
Taking multivitamins, omega-3, probiotics or vitamin D supplements may lessen the risk of testing positive for SARS-CoV-2, the virus responsible for COVID-19 infection — at least among women, indicates a large population study.
Novel drug regenerates erectile nerves damaged by prostate surgery
Researchers have developed a topical drug that regenerates and restores the function of erectile nerves damaged by radical prostatectomy, the most common treatment for localized prostate cancer. The drug was tested in rats.
Mirror, mirror: Viewing your own face, even subconsciously, is rewarding
Researchers have found that the subliminal presentation of images of one’s own face activates a central component of the dopamine reward pathway, thus illuminating the mechanisms behind our powerful ability to automatically prioritize the processing of our own face. These findings have important implications for understanding the neural processes involved in automatic self-advantage in face processing, as well as discriminating the processes involved in supraliminal (conscious) and subliminal (subconscious) facial perceptions.
Why climate change is driving some to skip having kids
A new study finds that overconsumption, overpopulation, and uncertainty about the future are among the top concerns of those who say climate change is affecting their reproductive decision-making.
Do covid vaccines contain GMO “Magneto” protein capable of remotely controlling behavior, brain activity?
American researchers have developed a new method of mind control that sounds oddly similar to what some suspect is contained within Wuhan coronavirus (Covid-19) “vaccines.”
Using genetic engineering, “Frankenstein” scientists have reportedly developed a genetically modified (GMO) protein known as “Magneto” that allows behaviors and brain function to be remotely controlled externally.
Healthy lifestyle linked to better cognition for oldest adults — regardless of genetic risk
A new study finds people who consume two servings of fruit per day have 36% lower odds of developing type 2 diabetes than those who consume less than half a serving.
‘Prescription’ to sit less, move more advised for mildly high blood pressure and cholesterol
Physical activity is the optimal first treatment choice for adults with mild to moderately elevated blood pressure and blood cholesterol who otherwise have low heart disease risk. About 21% of adults in the US with mild to moderately raised blood pressure and 28-37% of those with mild to moderate elevated cholesterol levels may be best served by a prescription for lifestyle-only treatment, which includes increasing physical activity.
Overconfidence in news judgment and false news susceptibility
A new study published in Proceedings of National Academics of Sciences finds that individuals who falsely believe they are able to identify false news are more likely to fall victim to it. In the article published today, Ben Lyons, assistant professor of communication at the University of Utah, and his colleagues examine the concern about the public’s susceptibility to false news due to their inability to recognize their own limitations in identifying such information.
AR can improve the lives of older adults, so why are apps designed mainly for youngsters?
Older people affected by memory loss have much to gain from AR technology, yet a study exploring the use of augmented reality to support older adults at home finds the user interface is sometimes confusing for those aged 50+.
It’s true: Stress does turn hair gray (and it’s reversible)
A new study offers quantitative evidence linking psychological stress to graying hair in people.
Switching from a Western diet to a balanced diet may reduce skin, joint inflammation
Diet rich in sugar and fat leads to disruption in the gut’s microbial culture and contributes to inflammatory skin diseases such as psoriasis. Research shows that switching to a more balanced diet restores the gut’s health and suppresses inflammation.
How the surfaces of silicone breast implants affect the immune system
Every year, about 400,000 people receive silicone breast implants in the United States. According to data from the U.S. Food and Drug Administration, a majority of those implants need to be replaced within 10 years due to the buildup of scar tissue and other complications.
Sugar overload may be a recipe for long-term problems
Children who consume too much sugar could be at greater risk of becoming obese, hyperactive, and cognitively impaired, as adults, according to the results of a new study.
An omega-3 that’s poison for tumors
3D tumors that disintegrate within a few days thanks to the action of a well-known omega-3 (DHA, found mainly in fish) — this is a promising discovery. Hungry for fatty acids, tumor cells in acidosis gorge themselves on DHA but are unable to store it correctly and literally poison themselves. The result? They die.
New discovery shows human cells can write RNA sequences into DNA
In a discovery that challenges long-held dogma in biology, researchers show that mammalian cells can convert RNA sequences back into DNA, a feat more common in viruses than eukaryotic cells.
