Published DNA barcoding identifies the plants a person has eaten (via sciencedaily.com) Original source
DNA barcoding is now being used to identify the plant matter in human feces, revealing what a person has eaten. A reliable genetic marker for plant-based foods can be retrieved from poop, showing not only what was eaten, but in what relative amounts. The technique should improve clinical trials, nutrition studies and more.
Published Molecular imaging identifies brain changes in response to food cues; offers insight into obesity interventions (via sciencedaily.com) Original source
Molecular imaging with 18F-flubatine PET/MRI has shown that neuroreceptors in the brains of individuals with obesity respond differently to food cues than those in normal-weight individuals, making the neuroreceptors a prime target for obesity treatments and therapy. This research contributes to the understanding of the fundamental mechanisms underlying obesity and offers valuable insights into potential medical interventions.
Published Follow the leader: Researchers identify mechanism of cancer invasion (via sciencedaily.com) Original source
A cancerous tumor is the accumulation of cells uncontrollably dividing, some of which can invade other parts of the body. The process is difficult to predict in detail, and eradicating the cells poses even greater difficulty. Now, a research team has revealed how the exodus initiates, shedding light on a potential therapeutic target to halt the invasion and providing a prognostic marker to help clinicians select the best treatment option.
Published Poor sense of smell linked to increased risk of depression in older adults (via sciencedaily.com) Original source
In a study that followed more than 2,000 community-dwelling older adults over eight years, researchers say they have significant new evidence of a link between decreased sense of smell and risk of developing late-life depression.
Published Lean body mass, age linked with alcohol elimination rates in women (via sciencedaily.com) Original source
Research links women's lean body mass with how quickly they eliminate alcohol from their system. Women with obesity and those who are older eliminate alcohol from their bloodstreams faster than those of normal weight and those who are younger.
Published All the immunity, none of the symptoms (via sciencedaily.com) Original source
Scientists found pairing specific diets with diarrheal disease-causing bacteria can create lasting immunity in mice without a need to ever experience symptoms. The findings pave the way for vaccine development that could reduce symptoms and mortality of diarrheal illness and other diseases in humans.
Published Pain not perceived in the same way in people with Alzheimer's Disease (via sciencedaily.com) Original source
New research has found that in a mouse model mimicking Alzheimer's Disease (AD) pain signals are not processed in the same way as in healthy mice.
Published Omega-3 fatty acids linked to slower decline in ALS (via sciencedaily.com) Original source
People with amyotrophic lateral sclerosis (ALS) who eat more foods high in certain omega-3 fatty acids like flaxseed oil, walnuts, canola oil and pumpkin seeds may have a slower physical decline from the disease and may have a slightly extended survival. Researchers also found an omega-6 fatty acid may be beneficial. The study does not prove that these omega fatty acids slow decline of ALS or extend survival; it only shows an association.
Published Loss of Y chromosome in men enables cancer to grow (via sciencedaily.com) Original source
As men age, some of their cells lose the very thing that makes them biological males -- the Y chromosome -- and this loss hampers the body's ability to fight cancer, according to new research. The study found that loss of the Y chromosome helps cancer cells evade the body's immune system. This common impact of the aging process in men results in aggressive bladder cancer, but somehow also renders the disease more vulnerable -- and responsive -- to a standard treatment called immune checkpoint inhibitors.
Published Ketone supplements worsen performance in trained endurance athletes, researchers find (via sciencedaily.com) Original source
Kinesiologists at McMaster University have found ketone supplements, used by some athletes hoping to cross the finish line faster, may in fact worsen performance. The new study tackles contradictory research findings related to the effectiveness of ketone supplements, which have gained popularity among athletes seeking a competitive advantage.
Published New findings show mitochondrial DNA fragments in blood as important biomarkers for aging and inflammation (via sciencedaily.com) Original source
In an eight-year study of more than 600 community-dwelling older adults, researchers say they have further linked levels of cell-free DNA (DNA fragments resulting from cell death) circulating in the blood to chronic inflammation and frailty. The study is novel and expands on previous work, the investigators say, because it focused on mitochondrial DNA rather than solely genomic DNA, as previously reported.
Published Close up on aging reveals how different cell types in the body age at different pace (via sciencedaily.com) Original source
A team or researchers reports the first Aging Fly Cell Atlas (AFCA), a detailed characterization of the aging process in 163 distinct cell types in the laboratory fruit fly. Their in-depth analysis revealed that different cell types in the body age differently, each cell type following a process involving cell type-specific patterns. AFCA provides a valuable resource for researchers in the fruit fly and aging communities as a reference to study aging and age-related diseases and to evaluate the success of anti-aging strategies.
Published Ultra small molecule as a new target for Alzheimer's disease? (via sciencedaily.com) Original source
A new study shows that a very small molecule called microRNA-132 can have a significant impact on different brain cells and may play a role in Alzheimer's disease.
Published Fewer meals may prevent Type 2 diabetes, obesity (via sciencedaily.com) Original source
When intermittent fasting became all the rage among Hollywood celebrities, skeptics balked at the idea of skipping meals. But new research suggests the celebs might not have been that far off. The review found that a specific type of restricted eating may reduce the chances of developing Type 2 diabetes and improve your overall health. Known as time-restricted eating, this type of fasting means having regular but fewer meals, cutting out late-night snacks and not eating for 12 to 14 hours (often overnight).
Published Altered gut bacteria may be early sign of Alzheimer's disease (via sciencedaily.com) Original source
Alzheimer's disease causes changes to the brain that begin two decades or more before symptoms appear. A study reveals that the bacteria that live in the gut also change before Alzheimer's symptoms arise, a discovery that could lead to diagnostics or treatments for Alzheimer's disease that target the gut microbiome.
Published The latest weapon against cancer is ... a keto diet? (via sciencedaily.com) Original source
Keto diets shrink pancreatic and colorectal tumors by starving them of the glucose they need to survive. But they also speed up development of a lethal wasting disease called cachexia. In mice, researchers have found that pairing keto with a corticosteroid prevents cachexia and increases survival.
Published Taurine may be a key to longer and healthier life (via sciencedaily.com) Original source
A study finds that deficiency of taurine, a molecule produced in our bodies, drives aging, and taurine supplements can improve health and increase lifespan in animals.
Published The IL-17 protein plays a key role in skin aging (via sciencedaily.com) Original source
A team of scientists has discovered that IL-17 protein plays a central role in skin aging. The study highlights an IL-17-mediated ageing process to an inflammatory state.
Published Sabotage and collusion could be derailing your weight loss journey, finds study (via sciencedaily.com) Original source
Family and loved ones may be conspiring to sabotage your weight loss journey, according to a new study. The study is part of a growing body of evidence which suggests that not all social support results in positive health outcomes.
Published Diet tracking: How much is enough to lose weight? (via sciencedaily.com) Original source
Keeping track of everything you eat and drink in a day is a tedious task that is tough to keep up with over time. Unfortunately, dutiful tracking is a vital component for successful weight loss, however, a new study finds that perfect tracking is not needed to achieve significant weight loss.
