Although plastic particles in the air are increasingly coming into focus, knowledge about their distribution and effects is still limited. Chemical analyses from Leipzig now provide details from Germany for the first time: around 4% of the particulate matter consists of plastic. Around two-thirds of this comes from tyre abrasion. Extrapolated, this means that people in a city like Leipzig inhale approximately 2.1 micrograms of plastic per day through the air, which increases the risk of death from cardiovascular disease by 9% and from lung cancer by 13%. These findings underscore the need to take global action against plastic pollution and to examine air quality and health at the regional level, write researchers from the Leibniz Institute for Tropospheric Research (TROPOS) and Carl von Ossietzky University Oldenburg in the journal Communications Earth & Environment, published by the Nature Publishing Group. The study was conducted as part of the Leibniz Association-funded project "AirPlast".

 Patients with a common form of kidney cancer called clear cell renal cell carcinoma (ccRCC) who have a high risk of recurrence after surgery showed significantly improved disease-free survival when treated with an oral combination regimen that includes belzutifan, a HIF-2α inhibitor, given with standard immune therapy pembrolizumab. These findings, from the phase 3 LITESPARK-022 study, are presented today by Dr. Toni Choueiri of Dana-Farber Cancer Institute at the 2026 American Society of Clinical Oncology Genitourinary Cancers Symposium (ASCO GU) in San Francisco, California, from Feb. 26-28.

Breast cancer (BCA) is one of the most common cancers worldwide, with a high rate of incidence and mortality. This review provides global information on BCA therapy using curcumin. Chemotherapy, as an effective treatment for different stages of BCA, and curcumin, generally regarded as safe compound and an alternative to synthetic drugs, have been described for the treatment of BCA. A few parameters, including nano-curcumin versus bulk curcumin and its encapsulated form versus its corresponding free form, have been discussed. Curcumin, a safe and edible compound with antitumor properties, is a promising medicinal compound for the treatment of BCA. Encapsulation of curcumin enhances its stability and anticancer efficiency. Nano-curcumin exhibits superior properties when compared to its bulk counterparts, leading to notable interactions and effects.

Circulating tumor DNA, or ctDNA, can predict metastatic risk in patients who receive bladder-sparing treatment for muscle-invasive bladder cancer, but it is not a good predictor of local recurrence within the bladder, according to new data presented today by Fox Chase Cancer Center researchers.

A team from the Monash University Biomedicine Discovery Institute in Australia has identified a tick-derived evasin that can bind to two major classes of chemokines, a discovery that is important for the development of therapeutics targeting inflammatory and autoimmune diseases. Until now, scientists had identified only evasins that selectively block chemokines within a single class.
