In a major advance for the treatment of the deadly brain cancer glioblastoma, scientists used ultrasound technology to penetrate the blood-brain barrier and provide a small dose of a chemotherapy and immunotherapy drug cocktail. The study found that this treatment boosted the immune system's recognition of the cancer cells and could lead to a new treatment approach.

Innate immune cells including macrophages and neutrophils have unique properties that allows them to quickly accumulate in large numbers at the site of infection or injury. A new study establishes that macrophage in the adult ischemic muscle induce a phenotype switch into mural cells to support restoration of functional blood flow and thereby promote healing. This finding pinpoints macrophages as a potential target for therapeutically enhancing vascular integrity and healing of ischemic injuries.

How hard is it to stop taking antidepressants? If countless Internet posts and a number of scientific studies are to be believed, discontinuing these medications is highly problematic, and doctors often underestimate the difficulties involved. But it is unclear how common discontinuation symptoms actually are. Researchers have now conducted a systematic review and meta-analysis. They conclude that one in three people reports symptoms after discontinuing antidepressant treatment, but half of those symptoms are attributable to negative expectations (the nocebo effect).

Some say the next step in human evolution will be the integration of technology with flesh. Now, researchers have used virtual reality to test whether humans can feel embodiment -- the sense that something is part of one's body -- toward prosthetic 'hands' that resemble a pair of tweezers. They report that participants felt an equal degree of embodiment for the tweezer-hands and were also faster and more accurate in completing motor tasks in virtual reality than when they were equipped with a virtual human hand.
