How Stress is Fundamentally Changing our Memories

Researchers at The Hospital for Sick Children (Sick Kids) have uncovered that stress changes how our brain encodes and retrieves aversive memories, and discovered a promising new way to restore appropriate memory specificity in people with post-traumatic stress disorder (PTSD).

Research Study

Resistant Bacteria Can Regain Susceptibility to Antibiotics

With the help of a study, researchers have revealed that resistant bacteria can regain susceptibility to antibiotics when the treatment is combined with a material equipped with antibacterial peptides. They further state that antibiotics can achieve a 64-fold increase in bactericidal effect when used together with the material, whose antibacterial properties are also greatly enhanced by this combination.

Researchers showed that a laser beam can sometimes act like a solid object and cast a shadow that is visible to the naked eye. In the picture, the shadow appears as the horizontal line traversing the blue background. (Source: R. A. Abrahao, H. P. N. Morin, J. T. R. Pagé, A. Safari, R. W. Boyd, J. S. Lundeen)

The Surprising Shadow of a Laser Beam

Imagine a shadow not cast by a solid object, but by light itself. Scientists have uncovered a way for laser beams to block one another, creating visible shadows and redefining our understanding of optics. This discovery could unlock groundbreaking applications in precision light control.
