Humans may have colonized Madagascar later than previously thought

New archaeological evidence from southwest Madagascar reveals that modern humans colonized the island thousands of years later than previously thought, according to a study published October 10, 2018 in the open-access journal PLOS ONE by Atholl Anderson from the Australian National University, Canberra, Australia, and colleagues. |SOURCE| [...] Read more

Reading the story of the developing human heart

How do you mend an injured heart? We don’t yet know – but the answer is likely to lie in how the heart builds itself in the developing embryo one cell at a time. |SOURCE| In a study published today in Cell Stem Cell, Australian researchers report on the most in-depth study to date of exactly how human stem cells can be turned into heart cells. The [...] Read more

Gamma rays illuminate one of the Milky Way’s weirdest objects

In a first, astronomers have discovered how the tiny cousins of massive quasars can generate high-energy light at the tips of their fast-moving jets. |SOURCE| At vast cosmic distances, supermassive black holes called quasars gobble up matter into accretion disks that shine so brightly, they overpower the light from entire galaxies. Closer to home, [...] Read more

The gene code of growing limbs

Scientists from EPFL and the University of Geneva have discovered a “code” of architect genes that are expressed in specific combinations during the development of hands and fingers. The study decrypts developmental gene expression at the level of the single cell in developing limbs and expands our understanding of the genetics behind growing [...] Read more
