Biological microorganisms are energy efficient, proliferate easily, and move autonomously. This makes them ideal sources of power for biohybrid machines. Scientists have now designed the first micromotors powered by algae. If you thought animals driving cars was impressive, get a load of this. The alga in question is called Chlamydomonas reinhardtii, a single-celled green alga. […]

Just A Small Rise In Earth’s Oxygen Levels Led To The Cambrian Explosion And Its Evolutionary Leaps
New research shows that the Cambrian explosion, one of the most important interludes in the story of life on Earth, may have been triggered by a small increase in oxygen levels. Using datasets from an international consortium of scientists, the team show that modest changes in oxygen levels may have been enough to cause the […]
This Is What Neanderthal And Denisovan Faces Looked Like
Your face is the result of thousands of years of lovemaking between multiple human species, with Neanderthals, Denisovans, and Homo sapiens being the main players in this ancient three-way romance. Because of a lack of physical evidence, however, we don’t really know how the features we’ve inherited compare to those of our extinct lovers – […]
Neutron Star Spotted Shooting A Jet Like A Garden Sprinkler For First Time
Astronomers have spotted a neutron star whose jet is changing direction for the first time. Likened to a garden sprinkler, the jet is coming from the phenomenal object Circinus X-1, one of the brightest and best-studied objects in the X-ray sky. However, it turns out that there is a lot more to discover about this […]
The First Cave Has Been Found On The Moon – Is It Ready For Occupation?
A tunnel has been identified under the surface of the Moon for the first time, appropriately on the Sea of Tranquility where humans first set foot. Although this particular spot is not a likely place to build a future colony, where there is one cave there are likely to be more, boosting the prospects for […]
