Climate change presents tremendous challenges, especially for people in the Global South. Two international studies led by Charité—Universitätsmedizin Berlin have investigated how the population in sub-Saharan Africa is coping with rising temperatures and the threat of infection—and what can be done about it. Reporting in the journals The Lancet Planetary Health and Nature Medicine, the researchers relate that women in agriculture suffer more from rising temperatures, while simple measures can improve domestic living conditions. The results are also relevant for adapting to climate change in Germany.

Researchers at Johannes Gutenberg University Mainz (JGU) have developed a method that gives access to the valuable raw materials formate and hydrogen from the waste product glycerol.

Researchers have discovered how bacteria break through spaces barely larger than themselves, by wrapping their flagella around their bodies and moving forward. Using a microfluidic device that mimics insect gut channels, the team revealed a remarkable "flagellar wrapping" motion that lets symbiotic bacteria pass through 1-micrometer-wide tunnels. Genetic manipulation and mathematical calculation showed that the flexibility of a tiny joint in the flagellum, called the hook, is crucial for this screw-like movement and even determines whether the bacteria can successfully infect their insect hosts.

Virtual reality (VR) and augmented reality (AR) are technologies that allow users to immerse themselves in digital worlds or enhance their surroundings with computer-generated filters or images, respectively.

What do Thomas Edison and 2010 Nobel Prize in physics winners Konstantin Novoselov and Andre Geim have in common? According to a recent publication from the lab of Rice University's James Tour in ACS Nano, it could be graphene—an answer that might have confused Edison, who died almost 20 years before physicist P.R. Wallace proposed such a substance could exist and nearly 80 years before Novoselov and Geim were awarded a Nobel Prize for isolating and characterizing it.

Cancer and Alzheimer's are two of the most common chronic diseases associated with aging. For years, doctors have known about a curious aspect of these two conditions: people who survive cancers are significantly less likely to develop Alzheimer's. While this link has been observed in the data for some time, the biological reasons for it have remained a mystery. Now, a new study published in the journal Cell has discovered a possible explanation.

Lung cancer varies widely from patient to patient, and that diversity makes it hard to find effective treatments. Researchers at the Berlin Institute of Health at Charité (BIH) have developed a method to evaluate multiple therapeutic approaches on patient-derived "tumoroids"—miniature tumors grown from tissue removed during surgery at Charité.

Nature is, of course, the master engineer—been there, seen it, solved it.
