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 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 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 via IFTTT

Sea otters keep remaining California kelp forests alive

Sea otters have long been recognized as a classic example of a keystone species, a dominant predator that maintains the balance of kelp forest ecosystems by controlling populations of sea urchins, which are voracious kelp grazers. from Pocket via IFTTT

How fast is the universe expanding? Galaxies provide one answer

Determining how rapidly the universe is expanding is key to understanding our cosmic fate, but along with more precise data comes a conundrum. Estimates based on measurements in our current universe don't agree with extrapolations from shortly after the Big Bang some 13.8 billion years ago. from Pocket via IFTTT
