Advances in bio-technologies and computer software have helped make genome sequencing much more common than in the past. But still in question are both the accuracy of different sequencing methods and the best ways to evaluate these efforts. Now, computer scientists have devised a tool to better measure the validity of genome sequencing.
How can bacteria protect themselves from lethal infection by viral parasites? One extreme way is for individual cells to commit suicide when infected, thereby preventing or limiting viral replication and protecting the rest of the bacterial population from subsequent infections.
Scientists have believed that microscopic organisms in the gut, microbiota, might play a crucial role in gaining weight but were never able to prove it. Groundbreaking research by a Chinese scientist has revealed a precise link.
Growing new blood vessels in the lab is a tough challenge, but a Johns Hopkins engineering team has solved a major stumbling block: how to prod stem cells to become two different types of tissue that are needed to build tiny networks of veins and arteries.
An international consortium with representatives from most of the world's major cotton-producing countries, led by Regents Professor Andrew Paterson of the University of Georgia and including Candace Haigler, a North Carolina State University professor of crop science and plant biology, has described the first 'gold-standard' genome sequence for cotton.
Nylon, Kevlar and other synthetic fabrics: Step aside. If new scientific research pans out, people may be sporting shirts, blouses and other garments made from fibers modeled after those in the icky, super-strong slime from a creature called the hagfish.
Cedars-Sinai Heart Institute researchers have reprogrammed ordinary heart cells to become exact replicas of highly specialized pacemaker cells by injecting a single gene (Tbx18) - a major step forward in the decade-long search for a biological therapy to correct erratic and failing heartbeats.
The software, which will be used to control Organovo's NovoGen MMX bioprinter, will represent a major step forward in usability and functionality for designing three-dimensional human tissues, and has the potential to open up bioprinting to a broader group of users.
