Now scientists have the oldest complete set of smallpox genes, after they went hunting for viral DNA in a sample of skin from a mummified young child, probably a boy, that was found in a crypt underneath a Lithuanian church.
Mix of Graphene With ‘Silly Putty’ Yields Extremely Sensitive Sensor
Mixing graphene—a material made of single-atom-thick layers of carbon—with homemade “Silly Putty” produces a sensor so sensitive that it can detect the tiny footsteps of spiders, according to new research.The uses could be endless, but include wearable health trackers.
