Expert comment: How do wildfires affect health and what can be done about it?

For people living in the northern hemisphere, this summer has been beset by deadly wildfires across parts of Europe, the U.S. and Canada. In the U.K., more than 21,000 hectares (52,000 acres) had already burned by late July 2026 across 66 fires larger than 30 hectares (74 acres), while England and Wales recorded their driest July in nearly two centuries and many areas moved into official drought.

Study points to new target for treating aggressive brain cancer

Glioblastoma remains one of the deadliest cancers, with limited treatment advances and tumors that often resist radiation and chemotherapy. New research from The Ohio State University Comprehensive Cancer Center–Arthur G. James Cancer Hospital and Richard J. Solove Research Institute points to SET as a potential target for making glioblastoma cells more vulnerable to treatment.

Two-stage process helps metastatic cancer cells hide, then multiply in the lungs

Most cancer deaths are caused not by the initial tumor but by the spread of cancer cells to distant organs in the process called metastasis. Since it occurs at the cellular level, the earliest stages of metastasis are difficult to observe in patients. A new study, published in Science, has made headway in understanding this process by mapping how some cancer cells survive in a new organ, even when most are eliminated by the immune system.
