Polis issues statewide stay-at-home order
CENTENNIAL, Colo. (KDVR) — Gov. Jared Polis issued a statewide stay-at-home order Wednesday afternoon. It goes into effect 6 a.m. Thursday and will last until April 11.
Many Coloradans, including the vast majority of people in metro Denver, live in counties where stay-at-home orders have already been announced.
Polis said he is issuing the order to save Coloradans’ lives.

Machine Automates Assembly Of Small Molecules
A new automated machine can synthesize a range of small organic molecules with the push of a button. The synthesizer uses a chemical method that pieces together molecules from modular building blocks. With this technique, the machine synthesized 14 classes of molecules, including some complicated ones with multiple rings.
The growth of an organism rides on a pattern of waves
When an egg cell of almost any sexually reproducing species is fertilized, it sets off a series of waves that ripple across the egg’s surface. These waves are produced by billions of activated proteins that surge through the egg’s membrane like streams of tiny burrowing sentinels, signaling the egg to start dividing, folding, and dividing again, to form the first cellular seeds of an organism.
Now MIT scientists have taken a detailed look at the pattern of these waves, produced on the surface of starfish eggs. These eggs are large and therefore easy to observe, and scientists consider starfish eggs to be representative of the eggs of many other animal species.
In each egg, the team introduced a protein to mimic the onset of fertilization, and recorded the pattern of waves that rippled across their surfaces in response. They observed that each wave emerged in a spiral pattern, and that multiple spirals whirled across an egg’s surface at a time. Some spirals spontaneously appeared and swirled away in opposite directions, while others collided head-on and immediately disappeared.
