Researchers discover intake of FDA-approved drug modulates disease progression in Alzheimer’s disease model — ScienceDaily

[ad_1] Indiana University School of Medicine researchers found that niacin limits Alzheimer’s disease progression when used in models in the lab, a discovery that could potentially pave the way toward therapeutic approaches to the disease. The study, recently published in Science Translational Medicine, investigates how niacin modulates microglia response to amyloid plaques in an Alzheimer’s…

Do older adults using statins have lower risk of developing Parkinsonism later? Study finds drug therapy associated with 16% lower risk — ScienceDaily

[ad_1] Parkinsonism is a term for a group of neurological conditions that cause movement problems including tremors, slowed movement and stiffness, with Parkinson’s disease being one of the better knowns causes. A new study suggests that older people taking statin drugs have a lower chance of developing parkinsonism later compared to people who were not…

First study to shed light on ambient particulate matter in tribal lands across the U.S. — ScienceDaily

[ad_1] A new study at Columbia University Mailman School of Public Health highlights disparities in fine particulate matter (PM2.5) trends between American Indian (AI) and non-AI populated counties of the U.S. PM2.5 is one of several air pollutants regulated by the U.S. Environmental Protection Agency (EPA), with the current annual standard set at 12?g/m3. Downward…

Older wildfire smoke plumes can affect climate — ScienceDaily

[ad_1] Aerosols carried in wildfire smoke plumes that are hundreds of hours old can still affect climate, according to a study out of the University of California, Davis. The research, published in the journal Environmental Science and Technology, suggests that wildfire emissions even 10 days old can affect the properties of aerosols — suspended liquid…

Revamped design could take powerful biological computers from the test tube to the cell — ScienceDaily

[ad_1] Tiny biological computers made of DNA could revolutionize the way we diagnose and treat a slew of diseases, once the technology is fully fleshed out. However, a major stumbling block for these DNA-based devices, which can operate in both cells and liquid solutions, has been how short-lived they are. Just one use and the…

Dense bones allowed Spinosaurus to hunt underwater — ScienceDaily

[ad_1] Spinosaurus is the largest predatory dinosaur known — over two metres longer than the longest Tyrannosaurus rex – but the way it hunted has been a subject of debate for decades. In a new paper, published today in Nature, a group of palaeontologists have taken a different approach to decipher the lifestyle of long-extinct…

Scientists discover novel master regulator that boosts an immune cell’s energy for tissue invasion — ScienceDaily

[ad_1] For life to survive, it needs to respond to challenges, particularly by adapting the activity of its immune system. As we have seen with Covid, outside infectious agents are constantly trying to gain a foothold within the body. But how can immune cells move into new tissues to find and destroy such infections? By…

New method of pancreatic islet cryopreservation marks breakthrough for diabetes cure — ScienceDaily

[ad_1] Engineering and medical researchers at the University of Minnesota Twin Cities and Mayo Clinic have developed a new process for successfully storing specialized pancreatic islet cells at very low temperatures and rewarming them, enabling the potential for on-demand islet transplantation. The breakthrough discovery in cryopreservation is a major step forward in a cure for…

First study to explore prosocial development of adults conceived with assisted reproductive technology show positive results — ScienceDaily

[ad_1] Being conceived via assisted reproductive technology (ART), such as IVF, may provide some advantages in quality of life in adulthood, according to the results of a new study. The results of the study, published in Human Fertility, offer reassuring news for people who have been conceived with ART — and those who need to…

Firefighters’ risk of irregular heartbeat linked to number of on-the-job fire exposures — ScienceDaily

[ad_1] Among firefighters, the risk of having an irregular heart rhythm, known as atrial fibrillation (AFib), increases with the number of fires they respond to, according to new research published today in the Journal of the American Heart Association, an open access, peer-reviewed journal of the American Heart Association. Compared with people in other occupations,…
