View ArticleMycobacteria get all the advantages of sex with none of the downsides
Sexual reproduction is costly to those organisms that depend on it, like humans. For starters, only half of the population can bear offspring and the other half has to work hard to make sure they're...
View ArticleResearch suggests Madagascar no longer an evolutionary hotspot
Madagascar has long been known as a hotspot of biodiversity. Although it represents only one percent of the earth's area, it is home to about three percent of all animal and plant species on the...
View ArticleBiceps bulge, calves curve, 50-year-old assumptions muscled aside
The basics of how a muscle generates power remain the same: Filaments of myosin tugging on filaments of actin shorten, or contract, the muscle – but the power doesn't just come from what's happening...
