This Strange Microbe May Mark One of Life’s Great Leaps 

A bizarre tentacled microbe discovered on the floor of the Pacific Ocean may help explain the origins of complex life on this planet and solve one of the deepest mysteries in biology, scientists reported on Wednesday.Two billion years ago, simple cells gave rise to far more complex cells. Biologists have struggled for decades to learn how it happened.

Mosquitoes engineered to repel dengue virus 

Scientists have synthetically engineered mosquitoes that halt the transmission of the dengue virus. Biologists developed a human antibody for dengue suppression in Aedes aegypti mosquitoes, the insects that spread dengue. The development marks the first engineered approach in mosquitoes that targets the four known types of dengue, improving upon previous designs that addressed single strains.

Researchers: Basic tenet of evolutionary theory “upended” by new find 

Looking past the tabloid prose, they say they found that selection can occur at the level of the epigenome. So what becomes of neo-Darwinism if selection isn’t tied to the all-powerful but accidental gene?

World’s oldest scorpions show no change from 437 million years ago |

It doesn’t sound as though they bothered with much evolution. How would we distinguish their origin from creation? At a certain point, does evolution become creation? Just wondering.

In death of dinosaurs, it was all about the asteroid — not volcanoes 

Volcanic activity did not play a direct role in the mass extinction event that killed the dinosaurs, according to an international team of researchers. It was all about the asteroid.
