Fluorescent proteins have revolutionized science, enabling researchers to tag and visualize individual molecules in living cells, tissues, and animals. Using these tools, researchers have watched viruses infect cells in real time, observed cellular trash collection, and tracked the signaling that spurs tumor growth.

How can ADHD be both a source of daily struggle for millions and a common trait among highly accomplished artists and innovators like Justin Timberlake and Simone Biles? The science behind this paradox is the focus of new research from Constructor University neuroscientist Dr. Radwa Khalil published in iScience, which explores the shared neurological mechanisms that connect creativity and attention. The study demonstrates how certain cognitive processes associated with ADHD—such as defocused attention—can also be potent sources of creative thinking when properly harnessed.

Many heat-related deaths in England occur during lower-level alerts that the public is least likely to respond to, with new research from the University of East London highlighting a critical gap between warning systems and public behavior.

A research team at IDM is leading the development of a sensor that paves the way for the rapid, selective and cost-effective detection of active tuberculosis. The device detects the presence of a protein secreted by Mycobacterium tuberculosis, the bacterium that causes the disease. It provides results in just 60 minutes—significantly less time than conventional methods, such as microbiological culture, which can take several weeks.

For decades, neuroscientists have been trying to uncover the neural processes that allow humans and various other animals to recall emotional experiences of past events. Past studies have identified a network of brain regions that support the encoding and consolidation of these memories. These regions include the hippocampus and the amygdala, as well as the para-hippocampal, perirhinal, prefrontal, parietal and retrosplenial cortices.

A new study has found comprehensive evidence that "weight-loss" GLP-1 receptor agonists such as semaglutide are effective in tackling the biological drivers of Alzheimer's disease. The study, published in the journal Molecular and Cellular Neuroscience, examined 30 preclinical studies investigating the effects of four GLP-1 receptor agonists—liraglutide; semaglutide; exenatide; and dulaglutide—on Alzheimer's disease pathology.

Researchers from the University of California San Diego Herbert Wertheim School of Public Health and Human Longevity Science have found that both anti-vaping advertising and widespread news coverage of a lung-injury outbreak tied to vaping—known as e-cigarette or vaping product use-associated lung injury (EVALI)—were critical in making 2019 a turning point in youth vaping prevalence in the United States.

Not everyone can sleep through rumbling traffic or a spouse's incessant snoring. If you do, you may pride yourself on being a "deep" or "heavy" sleeper. If you struggle to fall or stay asleep, you may consider yourself a "light" sleeper.

The stiffness of tumor tissue plays a role in how cancer spreads. Furthermore, stiff tumor tissue leaves traces in the affected cells, according to two recent research studies from Lund University. "This helps us to better understand how the mechanical properties of the tumor microenvironment actively drive cancer development and spread," says Vinay Swaminathan, senior lecturer at Lund University.

Erectile disorder (ED) refers to a persistent difficulty achieving or maintaining an erection sufficient for satisfying sexual activity. It affects millions of men worldwide, including up to 1 in 4 in the United States. Beyond physical functioning, erectile difficulties can impact sexual confidence, self-esteem, relationship satisfaction, and quality of life.
