Pancreas cells secrete neuroprotective factor
2025-01-28
Pancreas cells may produce a protein that can protect the brain from Alzheimer's disease. In individuals with Alzheimer's disease, a peptide known as amyloid-β accumulates and forms tangled plaques. People with diabetes have a higher probability of developing Alzheimer's disease, raising the possibility of a link between the cells that are disordered in diabetes—pancreatic β cells—and the onset of Alzheimer's disease. However, insulin supplementation may not halt the development of Alzheimer's disease. Toru Hosoi and colleagues ...

Q&A: How rate of CO2 rise can affect a global ocean current
2025-01-28
As we burn fossil fuels, the amount of carbon dioxide in Earth’s atmosphere is gradually rising, and with it, the planet’s average temperature. How fast the level of atmospheric carbon dioxide — and with it, the temperature — goes up matters for the ability of humans and ecosystems to adjust. A slower increase gives humans time to move away from low-lying coasts and animals time to move to new habitats.
It turns out the rate of that increase matters for non-living systems, too. A recent University of Washington study looked at how a major current in the Atlantic Ocean that includes the Gulf Stream will respond ...

The microbial ecosystems within our mouths may affect our cognitive function as we age, according to a study. Interventions such as prebiotics, including dietary nitrate, have potential for delaying cognitive decline.
About 15% of older adults have mild cognitive impairment, which is the largest risk factor for the development of dementia or Alzheimer’s disease. There is a known association between periodontitis—gum disease—and worsened cognitive function. Researchers have identified two possible links between the mouth and the mind: pathogenic ...
Paywalls shape newspaper coverage
2025-01-28
Adopting paywalls subtly shapes newspaper coverage, according to a study. Online journalism is increasingly found behind paywalls, as outlets pivot from funding their operations by selling ads to relying on subscriptions for revenue. This shift has raised questions about how newspapers might adjust their coverage to cater to paid subscribers' desires for popular news and soft news—entertainment, lifestyle, sports, and human-interest stories—at the expense of providing local news and maintaining democratic accountability. Paramveer S. Dhillon ...
Escaping the endosome: Bend lipids improve LNP mRNA delivery and gene editing
2025-01-28
Every time a shuttle docks with the International Space Station (ISS), a delicate dance unfolds between the shuttle's docking system and its counterpart on the station. Thanks to international standards, these mechanisms are universally compatible, ensuring astronauts and cargo can safely and seamlessly enter the station.
A similar challenge arises at the microscopic level when lipid nanoparticles (LNPs) — the revolutionary drug delivery vehicles behind the COVID-19 vaccines — attempt to deliver mRNA to cells. Optimizing the design and delivery of LNPs can greatly enhance their ability to deliver mRNA successfully, ...
