Metabolic diseases may be driven by gut microbiome, loss of ovarian hormones      (via sciencedaily.com)     Original source 

Mice that received fecal implants from donors that had their ovaries removed gained more fat mass and had greater expression of liver genes associated with inflammation, Type 2 diabetes, fatty liver disease and atherosclerosis. The findings may shed light on the greater incidence of metabolic dysfunction in postmenopausal women.

Air pollution linked to more signs of Alzheimer's in brain      (via sciencedaily.com)     Original source 

People with higher exposure to traffic-related air pollution were more likely to have high amounts of amyloid plaques in their brains associated with Alzheimer's disease after death, according to a new study. Researchers looked at fine particulate matter, PM2.5, which consists of pollutant particles of less than 2.5 microns in diameter suspended in air.

Bridging diet, microbes, and metabolism: Implications for metabolic disorders      (via sciencedaily.com)     Original source 

Mounting evidence suggests that the secret to understanding human health and combating metabolic diseases lies hidden within the microscopic world of our gut bacteria. Recent research reveals that a specific fatty acid produced by gut bacteria directly influences fat metabolism in animals. This research is pivotal as it sheds light on the complex interplay between the diet, gut microbiota, and host metabolic health, offering insights that could open new avenues in our approach to managing metabolic disorders.

Fasting-like diet lowers risk factors for disease, reduces biological age in humans      (via sciencedaily.com)     Original source 

Cycles of a diet that mimics fasting can reduce signs of immune system aging, as well as insulin resistance and liver fat in humans, resulting in a lower biological age, according to a new study.

New genetic therapy holds promise for ALS and frontotemporal dementia      (via sciencedaily.com)     Original source 

Neuroscientists have developed a single-dose genetic medicine that has been proven to halt the progression of both ALS and FTD in mice -- and may even offer the potential to reverse some of the effects of the fatal diseases. It may also hold opportunities for treating more common forms of dementia, such as Alzheimer's disease.

Double risk of dementia after mouth ulcer virus      (via sciencedaily.com)     Original source 

People who have had the herpes virus at some point in their lives are twice as likely to develop dementia compared to those who have never been infected. A new study confirms previous research on whether herpes can be a possible risk factor for dementia.

Exposure to Agent Orange damages brain tissue in ways similar to Alzheimer's disease      (via sciencedaily.com)     Original source 

Agent Orange, an herbicide used during the Vietnam War, is a known toxin with wide-ranging health effects. Even though Agent Orange has not been used for decades, there is increasing interest in its effects on the brain health of aging veterans. A new study reveals the mechanisms by which Agent Orange affects the brain and how those processes can lead to neurodegenerative diseases. The research shows that exposures to Agent Orange herbicidal chemicals damage frontal lobe brain tissue of laboratory rats with molecular and biochemical abnormalities that are similar to those found in early-stage Alzheimer's disease.

Non-invasive techniques to detect skin cancer      (via sciencedaily.com)     Original source 

A study has demonstrated that the appearance of ageing skin looks noticeably different compared to younger skin, when examined under polarized laser light. The scientists believe that their new finding could pave the way for new, non-invasive light-based techniques to detect diseases, including cancer, in older individuals. This could significantly enhance early-stage treatment options for various skin conditions.

Immune genes are altered in Alzheimer's patients' blood      (via sciencedaily.com)     Original source 

A new study has found the immune system in the blood of Alzheimer's patients is epigenetically altered. That means the patients' behavior or environment has caused changes that affect the way their genes work. Many of these altered immune genes are the same ones that increase an individual's risk for Alzheimer's. Scientists now theorize the cause could be a previous viral infection, environmental pollutants or other lifestyle factors and behaviors.

Faulty DNA disposal system causes inflammation      (via sciencedaily.com)     Original source 

Scientists discovered a pathway from mitochondrial DNA replication stress to immune system activation and inflammation, finding that endosomes responsible for disposing of dysfunctional mitochondrial DNA were leaking mitochondrial DNA into the cell and prompting the inflammatory immune response. The pathway provides new targets for therapeutics that disrupt inflammation during aging and disease.

The drugs used to treat erectile dysfunction may also be associated with a reduced risk of Alzheimer's disease, according to new research. The study does not prove that erectile dysfunction drugs reduce the risk of Alzheimer's disease. It only shows an association.

New direct links discovered between the brain and its surrounding environment      (via sciencedaily.com)     Original source 

In a recent study of the brain's waste drainage system, researchers discovered a direct connection between the brain and its tough protective covering, the dura mater. These links may allow waste fluid to leave the brain while also exposing the brain to immune cells and other signals coming from the dura. This challenges the conventional wisdom which has suggested that the brain is cut off from its surroundings by a series of protective barriers, keeping it safe from dangerous chemicals and toxins lurking in the environment.

Music may bring health benefits for older adults, poll suggests      (via sciencedaily.com)     Original source 

Three-quarters of people age 50 to 80 say music helps them relieve stress or relax and 65% say it helps their mental health or mood, according to a recent poll. Meanwhile, 60% say they get energized or motivated by music. Virtually all (98%) said they benefit in at least one health-related way from engaging with music.
