Previous studies have shown that psychedelic treatment with psilocybin relieved major depressive disorder symptoms in adults for up to a month. Now, in a follow-up study of those participants, the researchers report that the substantial antidepressant effects of psilocybin-assisted therapy, given with supportive psychotherapy, may last at least a year for some patients.

Nanomaterials have revolutionized the world of cancer therapy, and plant-derived nanoparticles have the added advantage of being cost-effective and easy to mass produce. Researchers have recently developed novel corn-derived bionanoparticles for targeting cancer cells directly, via an immune mechanism. The results are encouraging, and the technique has demonstrated efficacy in treating tumor-bearing laboratory mice. Moreover, no serious adverse effects have been reported in mice so far.
