Neanderthals may have been morning people, says new study
A new research paper finds that genetic material from Neanderthal ancestors may have contributed to the propensity of some people today to be "early risers," the sort of people who are more comfortable getting up and going to bed earlier......»»
Researchers create stable hybrid laser by 3D printing micro-optics onto fibers
For the first time, researchers have shown that 3D-printed polymer-based micro-optics can withstand the heat and power levels that occur inside a laser. The advance enables inexpensive, compact, and stable laser sources that would be useful in a vari.....»»
