• Glioblastoma (GBM) is a highly aggressive type of brain cancer. Even with current standard of care, 50% of patients die within 15 months of diagnosis. • This complex cancer is difficult to treat due to its location, structure, ability to spread quickly, high recurrence rate and severely limited treatment options. • GBM tumours can look identical under the microscope but respond differently to the same treatment. • With a national grant of about S$10 million, researchers in Singapore are working with overseas collaborators to address these challenges and develop new diagnostic and treatment options so patients can receive effective targeted therapy.

Publication bias, or the tendency of researchers and journals to not publish uninteresting findings, plagues much of the natural sciences and especially biomedical research. Hiroshima University researchers have developed a meta-analytic technique exploiting publicly available transcriptome databases that avoids the problem—and in so doing, discovered four genes previously unknown to be associated with responding to low-oxygen stress.

The chances of restoring fertility through sperm stem cell transplant are as random as a coin toss. But a team of scientists developed a new strategy that serves as a “weighted coin” that can favorably rig the odds to achieve outcomes where fertility is successfully restored.

Tomohiro Mochizuki tracks down viruses inside single-cell organisms thriving in boiling hot springs. His fieldwork is conducted in relatively extreme environments and, despite the significance of his investigations, he doesn’t need many fancy gadgets back at his lab at Japan’s Earth-Life Science Institute (ELSI). ARN asked Mochizuki about his virus-hunting exploits and what they involve.
