In the ever-escalating evolutionary battle with drug-resistant bacteria, humans may soon have a leg up thanks to adaptive, light-activated nanotherapy developed by researchers at the University of Colorado Boulder. Antibiotic-resistant bacteria such as Salmonella, E. Coli and Staphylococcus infect some 2 million people and kill at least 23,000 people in the United States each year. Efforts to thwart these so-called 鈥渟uperbugs鈥� have consistently fallen short due to the bacteria鈥檚 ability to rapidly adapt and develop immunity to common antibiotics such as penicillin.

The human gut harbors a teeming menagerie of over 100 trillion microorganisms and exercising early in life can alter that microbial community for the better, promoting healthier brain and metabolic activity over the course of a lifetime.

The Ebola virus and fruit bats have been waging a molecular battle for survival that may have started at least 25 million years ago.

Humans haven鈥檛 learned much in 2,000 years when it comes to religion and politics. Religion has led to social tension and conflict, not just in today鈥檚 society, but dating back to 700 B.C., according to a new study published today in Current Anthropology .
