Researchers have studied a new method to deliver antibiotics, specifically gentamicin, directly into the bladder tissue to better treat UTIs. They did this by creating nanogels combined with a special peptide (a small protein) that helps the drug get inside the cells where the bacteria are hiding. The results demonstrate that this approach proved highly effective when tested in animal models with UTIs, eliminating over 90% of the bacteria from... Read more ›

Researchers gathered emissions data from hundreds of US cities that either conducted a greenhouse gas emissions inventory, or reported they employed sustainability staff. The cities that conducted an inventory showed a statistically significant reduction in emissions between 2010 and 2015, while those with sustainability staff did not. Little research had previously been done to gauge effects of such measures and show that addressing emissions is meaningful, researchers argue. Read more ›

Until now, doctors knew hepatic stellate cells mainly as drivers of liver fibrosis. The actual functions of this cell type have hardly been studied to date. Researchers have now determined that hepatic stellate cells control liver metabolism as well as liver regeneration and size. The results of the study could contribute to new therapeutic approaches for liver diseases. Read more ›

Struggling to afford food today could mean heart problems tomorrow. Young adults experiencing food insecurity have a 41% greater risk of developing heart disease in midlife, even after accounting for demographic and socioeconomic factors, according to a new study. Food insecurity -- struggling to get enough nutritious food to stay healthy -- affects one in eight households in the U.S. each year. Read more ›

In developing hearts, cells shuffle around, bumping into each other to find their place, and the stakes are high: pairing with the wrong cell could mean the difference between a beating heart and one that falters. A study demonstrates how heart cells go about this 'matchmaking' process. The researchers model the intricate movements of these cells and predict how genetic variations could disrupt the heart development process in fruit flies. Read more ›

Climate change may lead to more precipitation and more intense floods. A new study shows that to understand the details of this relationship, it is important to distinguish between different types of rainfall and flood events -- namely, between short-term events that occur on a time scale of hours, and longer-term events that last several days. In each case, climate change has a different impact. Read more ›

Researchers have announced the creation of the first operating system designed for quantum networks: QNodeOS. The research marks a major step forward in transforming quantum networking from a theoretical concept to a practical technology that could revolutionize the future of the internet. Read more ›

Large, undisturbed forests are better for harboring biodiversity than fragmented landscapes, according to recent research. Ecologists agree that habitat loss and the fragmentation of forests reduces biodiversity in the remaining fragments. But ecologists don't agree whether it's better to focus on preserving many smaller, fragmented tracts of land or larger, continuous landscapes. The study comes to a clear conclusion. Read more ›

Microplastics have been found almost everywhere that scientists have looked for them. Now these bits of plastic -- from 1 to 62 micrometers long -- have been found in the filtered solutions used for medical intravenous (IV) infusions. The researchers estimate that thousands of plastic particles could be delivered directly to a person's bloodstream from a single 8.4-ounce (250-milliliter) bag of infusion fluid. Read more ›

The immune system typically can ramp up the body's defenses to clear out an invading threat without issue. Glitches can happen, however, with sepsis occurring when the mustered army of cells also attacks the body's own tissues and organs as if they were enemy combatants. Sepsis is dangerous, particularly when it isn't treated early, and it can lead to the even more deadly condition of septic shock -- a massive... Read more ›

A world first* study of more than 215,000 students, researchers found that while standardized tests measure academic skills, different dimensions of wellbeing -- emotional wellbeing, engagement, and learning readiness -- can play a crucial role in performance. Read more ›

Where there's water, there are waves. But what if you could bend water waves to your will to move floating objects? Scientists have now developed a technique to merge waves in a water tank to produce complex patterns, such as twisting loops and swirling vortices. Some patterns acted like tweezers or a 'tractor beam' to hold a floating ball in place. Other patterns made the ball spin and move precisely... Read more ›
