Stem cells have been holding great promise for regenerative medicine for years. However, one of the main limitations in the application of these therapies is the quality of the stem cells that can be generated in the laboratory. Now, a team from the Spanish National Cancer Research Centre (CNIO) has developed a new, simple and fast technology that enhances in vitro and in vivo the potential of stem cells to differentiate into adult cells.
By mapping molecular changes in the genome over time, UC San Diego researchers developed a formula to more accurately compare dog age to human age -- a tool that could also help them evaluate how well anti-aging products work.
States with the highest level of income inequality had a larger number of COVID-19-related deaths compared with states with lower income inequality. For instance, New York state, with the highest income inequality, had a mortality rate of 51.7 deaths per 100,000. This is 125 times greater than Utah, the state with the lowest income inequality and which had a mortality of 0.41 per 100,000 at the end of the period studied.
Showing people how their peers feel about diversity in their community can make their actions more inclusive, make members of marginalized groups feel more like they belong, and even help close racial achievement gaps in education, according to a new study.
Scientists have used advanced technology to 'micro-dissect' the first brain cells to perish in Alzheimer's disease. The result is a short list of genes that could represent new drug targets.
Real-world mobile phone data suggests a decline in the number of trips people made per day began before state-level stay-at-home policies were implemented, and the decline was strongly correlated with a reduction of COVID-19 case growth in the 25 most affected counties across the USA, according to a modelling study published in The Lancet Infectious Diseases journal.
Why do we age? What exactly is happening in our bodies? And can we do anything about it? Mankind has sought answers to these questions since time immemorial. While the pharmaceutical scientists Alexandra K. Kiemer and Jessica Hoppstädter from Saarland University are not claiming to have solved this ancient problem, they have uncovered processes within our immune system that contribute to ageing.
Eat a slab of steak and your resident gut bacteria get to work immediately to break it down. But new research shows that a metabolic byproduct, called TMAO, produced in the process can be harmful to the lining of arteries, making them age faster.
Using same-day traffic volumes for March 2019 and March 2020 across Florida, researchers examined the relationship of key governmental requests for public isolation and travel limitations. Results show the drastic changes in human behavior during the onset of the pandemic. Traffic volumes by March 22, 2020, dropped by 47.5% compared to that same point in 2019. Moreover, traffic declined in March 2020 corresponding with the governor's state of emergency declaration and school, restaurant, and bar closures.
Exercise can slow or prevent the development of macular degeneration and may benefit other common causes of vision loss, such as glaucoma and diabetic retinopathy, new research suggests.
