WOX9: A gene that’s a jack of all trades

Over evolutionary time scales, a single gene may acquire different roles in diverging species. However, revealing the multiple hidden roles of a gene was not possible before genome editing came along. from Pocket https://ift.tt/3dvp3Xq via IFTTT

Found in space: Complex carbon-based molecules

Much of the carbon in space is believed to exist in the form of large molecules called polycyclic aromatic hydrocarbons, or PAHs. Since the 1980s, evidence has indicated that these molecules are abundant in space, but they have not been directly observed. Now, a team of U.S. from Pocket https://ift.tt/3mahFVr via IFTTT

How do birds breathe so efficiently? Looped airways facilitate air flows

Birds breathe with greater efficiency than humans because of the structure of their lungs --looped airways that facilitate air flows that go in one direction -- a team of researchers has found. The results appear in Physical Review Letters. The U.S. from Pocket https://ift.tt/3mggOTi via IFTTT
