The liver is regularly bombarded with foreign substances, and is home to antigen-presenting cells that train the immune system to tolerate foreign proteins rather than attacking them. Delivering carefully selected protein fragments to the liver helps put a damper on […]
Our brains have a variety of different cells. We often here of neurons. There are also astrocytes and oligodendrocytes. Understanding how stem cells differentiate into the various cells can help us understand why development sometimes goes wrong and leads to […]
This article is a preprint and has not been certified by peer review. “In the UK, Italy, Japan, and France remarkable longevity is instead predicted by regional poverty, old-age poverty, material deprivation, low incomes, high crime rates, a remote region […]
The technology from researchers at ETH Zurich could create a self-regulating circuit. “When the fuel cell powered by glucose senses excess blood sugar, it powers up. This then stimulates the beta cells to produce and secrete insulin. As blood sugar […]
Making stem cells from differentiated cells just got a lot faster. “Our results highlight a distinct chemical reprogramming pathway that leads to a shortcut for the generation of human pluripotent stem cells, which represents a powerful strategy for human cell […]
“Their goal was to slow down the chemical reaction that creates polysulfides when the battery charges and discharges. … But what they found instead was something incredible: a chemical phase of sulfur that basically stops battery degradation!” ~ learn more
Like the link above, this is also about organoids. A bit farther ‘out there’, these researchers want to turn the lumps of brain cells into fast and efficient computers. Given the revolution happening in artificial intelligence on silicon, this could […]
“For years, the neuroscientist Sergiu Paşca has been a leader in the use of brain organoids in studies of human neurological disorders. His latest work, in which human cells become working parts of rat brains, carries that effort to new […]
“Extracts from these so-called ‘lion’s mane’ mushrooms have been used in traditional medicine in Asian countries for centuries, but we wanted to scientifically determine their potential effect on brain cells,” Professor Meunier said. ~ learn more
“Researchers found 40% fewer dementia diagnoses among the 4,637 participants who took vitamin D supplements, compared to the cohort that did not. Interestingly, the study also found that vitamin D supplements seemed to benefit a few subsets of participants more: […]
