Searching for an ancient syphilis DNA in newborns

Pictured are the left femur, two right humerus and a right hemifrontal bone belonging to at least two newborns found at “La Ermita de la Soledad ” in Huelva. All show… The ancient bones of newborns are very useful to recover the ancient DNA of the bacteria causing syphilis, the Treponema pallidum pallidum. This is the conclusion reached by a study led by Universitat Autònoma de Barcelona (UAB), which was able to obtain the ge Read more...

All wrapped up: K-State researcher’s graphene cloak protects bacteria, leading to better images

It’s a cloak that surpasses all others: a microscopic carbon cloak made of graphene that could change the way bacteria and other cells are imaged. Vikas Berry, assistant professor of chemical engineering at Kansas State University, and his research team are wrapping bacteria with graphene to address current challenges with imaging bacteria under electron microscopes. Berry’s method creates a carbon cloak that protects the bacteria, Read more...
