Scientists have turned blood cells from an 80-year-old into neural stem cells with a molecular age of less than 20, effectively reversing more than 60 years of cellular aging in the laboratory. The discovery offers a new way to investigate how cells become younger and could help researchers better understand age-related diseases such as Alzheimer's.
With the number of under-five deaths at an all-time recorded low of 5.2 million in 2019, disruptions in child and maternal health services due to the COVID-19 pandemic are putting millions of additional lives at stake The number of global under-five deaths dropped to its lowest point on record in 2019 – down to 5.2 million from 12.5 million in 1990, according to new mortality estimates released by UNICEF, the World Health Organization (WHO), the Population Division of the United Nations Department of Economic and Social Affairs and the World Bank Group. Since then, however, surveys by UNICEF a
Hungary's parliament passed a bill amending the 2021 "child protection law." The move is considered the first significant reversal of Orban's curbs targeting the LGBTQ+ community.
Ex-Wales hooker Scott Baldwin is convinced the 36-year-old's World Cup know-how can still help Wales in Australia.
A motion declaring Zionism a form of racism was passed by Green Party members on Sunday.
Stem cell transplants helped regenerate stroke-damaged brain tissue in mice, producing new neurons and restoring lost motor function. The treatment also improved blood vessels, inflammation, and the blood-brain barrier, raising hopes that a similar approach could eventually help repair the human brain after stroke.
Scientists found that declining levels of the brain protein Menin may help drive aging, with lower levels in mice linked to inflammation, cognitive decline, weaker bones, and thinner skin. Restoring Menin reversed several age-related changes, while the amino acid D-serine improved cognition, hinting at a potentially intriguing new target for healthy aging.
