Genetic switches play big role in human evolution

(Phys.org) —A Cornell study offers further proof that the divergence of humans from chimpanzees some 4 million to 6 million years ago was profoundly influenced by mutations to DNA sequences that play roles in turning genes ...

Tropical vagrants bigger, stronger survivors

(Phys.org) —Sydney marine researchers are one step further in solving the mystery of how tropical fishes, in response to rising sea temperatures and the impact of climate change, are shifting, and potentially surviving ...

Single cells: Same same but different

(Phys.org) —If half of a cell population were coloured white and the other half were coloured black, scientists should think all cells are grey. Conventional methods average over thousands of cells, overlooking any cell-to-cell ...

Mapping a route to stem cell therapies

Monash University researchers are shedding light on the complex processes that underpin the creation and differentiation of stem cells, bringing closer the promise of 'miracle' therapies.

Jekyll and Hyde corals tell different warming story

(Phys.org) —Like the rings of a tree trunk, Strontium-to-calcium ratios (Sr/Ca) in coral skeletons have been widely used to determine past ocean temperatures from yearly banded corals. However, scientists have now found ...

Stem cells use signal orientation to guide division, study shows

Cells in the body need to be acutely aware of their surroundings. A signal from one direction may cause a cell to react in a very different way than if it had come from another direction. Unfortunately for researchers, such ...
