After herpesviruses infect a cell, their genomes are assembled into specialized protein structures called nucelosomes. Many cellular enzyme complexes can modulate these structures to either promote or inhibit the progression of infection. Scientists studying how one of these complexes (EZH2/1) regulated herpes simplex virus (HSV) infection unexpectedly found that inhibiting EZH2/1 suppressed viral infection...

Scientists at the University of Oxford have developed a new method to 3D-print laboratory- grown cells to form living structures. The approach could revolutionise regenerative medicine, enabling the production of complex tissues and cartilage that would potentially support, repair or augment diseased and damaged areas of the body...

Researchers are first to reproducibly achieve the current blockade effect using atomically precise molecules at room temperature, a result that could lead to shrinking electrical components + boosting data storage + computing power. Current blockade is the ability to switch a device from the insulating to the conducting state where charge is added and removed one electron at a time.

Bonnie Choi, a graduate student in the Roy group created a single cluster of geometrically ordered atoms with an inorganic core made of just 14 atoms – resulting in a diameter of about 0...
