Scientists have successfully encoded a software exploit in a gene to remotely hack a computer. But why would anyone want to hack a computer with a malicious DNA strand? The researchers who developed it argue an attacker could use it to hack any computer in the DNA sequencing pipeline. This pipeline includes any facility that accepts DNA samples for computer-based gene sequencing and processing. An attacker could mess with a police investigation by tainting blood, hair, and saliva samples with injected malicious DNA they know will be sequenced on a computer. "Since DNA sequencing is rapidly progressing into new domains, such as forensics and DNA data storage, we believe it is prudent to understand
A Johns Hopkins University mathematician and computer scientist joined an international team of neuroscientists to create a complete map of the learning and memory center of the fruit fly larva brain, an early step toward mapping how all animal brains work. In a paper in the current issue of the journal Nature, the team reported on drawing up the map, known as a "connectome." The project could serve as a guide as scientists work their way up the animal kingdom and eventually chart connections among neurons in the brains of mammals. The part of the fruit fly larva brain used in the study corresponds roughly to the cerebral cortex in mammals. "Nobody's ever done a complete connectome" before, other
