A new study challenges a long-standing assumption about how cyanobacteria survive environmental stress. The study, led by researchers at the Israel Oceanographic and Limnological Research (IOLR)—the Kinneret Limnological Institute (KLI), shows that survival under prolonged heat stress is not determined solely by the ability to protect photosynthesis. Instead, survival may depend on a remarkable shift in cellular energy balance, with dark respiration compensating when photosynthetic electron...

CDC sleuthing helps decipher drug-resistant infection rise

Previous research from the Centers for Disease Control and Prevention (CDC) found that a dangerous variety of bacteria that cause drug-resistant infections, called NDM-producing carbapenem-resistant Enterobacterales (NDM-CRE), has become much more common in the United States, increasing by 461% from 2019–2023. Now, in a new study presented at ASM Microbe 2026, researchers set out to better understand what was behind this sudden increase, examining if it was driven by closely related strains...

New atlas reveals more about how the body's 'master gland' really works

A new study has created a detailed map of the pituitary gland, often called the body's "master gland" because it controls important functions such as growth, stress and reproduction. Researchers from the Center for Craniofacial & Regenerative Biology combined data from many studies to build a single, clearer picture of how this gland works. They created the Consensus Pituitary Atlas, along with an easy-to-use website where scientists can explore the data and analyze their own.

Caffeine Minimalists Rewrite Routines to Battle Coffee Jitters

Jun 13th, 2026 Caffeine Minimalists Rewrite Routines to Battle Coffee While plenty of Americans are emphatically unready to give up caffeine, many are experimenting with a new range of options beyond the traditional cup of hot java, paying heed to caffeine’s impact on their sleep, mood and energy level. Consumers are becoming more cognizant of “energy management” in their beverage choices, says Daniel Jhung, president of the coffee and beverage division of Nestlé USA.
