Researchers have isolated broad potential stem cells from amniotic fluid, which can give rise to various specialized cell types. These cells, named amniotic fluid-derived stem (AFS) cells, may represent an intermediate stage between embryonic and adult stem cells.
A large study found that carriers of the APOE4 gene, which increases Alzheimer's risk, showed the same normal age-related cognitive declines as non-carriers. The research suggests the higher-risk genotype acts only in later years to accelerate disease progression.
Scientists have discovered a supermassive black hole at the heart of a dwarf elliptical galaxy, VCC128, located 54 million light years away. The finding is significant as it shows that even small galaxies can host massive black holes, challenging previous assumptions.
Astronomers have created the first 3D map of the universe's dark matter distribution, revealing a web-like structure that confirms conventional theories on how galaxies formed. The map was derived from the Cosmic Evolution Survey and offers unprecedented detail on the large-scale filamentary structure of dark matter.
Astronomers have discovered an enormous halo of red giant stars surrounding the Andromeda galaxy, extending beyond its visible disk and indicating that it may be five times larger than previously believed. The discovery is based on observations of over 500,000 light-years of starry space using advanced telescopes.
Researchers developed a sensitive test for identifying drug-resistant strains of HIV in patients' bloodstreams. The test detects genetic changes that predict potential drug resistance, enabling personalized treatment guidance.
