Using an experiment carried into space on a NASA suborbital rocket, astronomers have detected a diffuse cosmic glow that appears to represent more light than that produced by known galaxies in the universe. The discovery suggests that many such previously undetected stars permeate what had been thought to be dark spaces between galaxies, forming an interconnected sea of stars.

Our genetic makeup influences whether we are fat or thin by shaping which types of microbes thrive in our body, according to a new study. Scientists identified a specific, little known bacterial family that is highly heritable and more common in individuals with low body weight. This microbe also protected against weight gain when transplanted into mice. The results could pave the way for personalized probiotic therapies that are optimized to reduce the risk of obesity-related diseases based on an individual's genetic make-up.

All multicellular creatures are descended from single-celled organisms. The leap from unicellularity to multicellularity is possible only if the originally independent cells collaborate. So-called cheating cells that exploit the cooperation of others are considered a major obstacle. Now, researchers capture the emergence of multicellular life in real-time experiments.

People shed more weight on an entirely plant based diet, even if carbohydrates are also included, a study has concluded. Other benefits of eating a vegan diet include decreased levels of saturated and unsaturated fat, lower BMIs, and improved macro nutrients.

The microbes living in people's guts are much less diverse than those in humans' closest relatives, the African apes, an apparently long evolutionary trend that appears to be speeding up in more modern societies, with possible implications for human health, according to a new study.
