Quantum pendulum clock overcomes classical accuracy limits and sheds light on quantum to classical transitions

When regional airlines leave a market, travelers are likely to see fewer flights and higher fares. The harder question is how much service disappears, how quickly prices rise and whether other airlines step in to fill the gap.

In the far north regions of Earth, where forests stretch across Alaska and Canada, climate change is unfolding at an accelerated pace. Arctic and boreal regions are warming two to four times faster than the global average, putting immense pressure on ecosystems that absorb CO2 and help slow climate change. Through photosynthesis, vast expanses of vegetation naturally pull carbon from the atmosphere and sequester it in their biomass.

A tiny sea creature might hold the secret to reversing the aging process. When treated with a brief series of electrical pulses, sea squirts experience dramatic and long-lasting health improvements that can significantly extend their lifespans, according to a new study by researchers at Stanford and other institutions.
