People with HIV and severe liver damage face a significant risk of liver cancer even after successfully treating hepatitis C with direct-acting antivirals (DAAs). This finding highlights the importance of ongoing monitoring for liver cancer in these patients. The study focused on individuals with HIV who had advanced liver fibrosis or cirrhosis. These conditions mak...
Aging is not just about wearing out like an old machine. It's more like a computer losing its software, not the hardware. Dr. David Sinclair, a Harvard geneticist, says that as we get older, the instructions that tell our cells what to do get mixed up. This is called the "information theory of aging. " It's like the cell's operating system getting corrupted, even tho...
Aging is a big deal, and not just because of wrinkles. It's about how our cells change and talk to each other. Once, scientists thought senescent cells, which are like old, grumpy cells that stop dividing, just hung out in one place. But now, they know these cells chat with other cells all over the body. They send out signals, like tiny messages in a bottle, that can...
Sea anemones, those fascinating creatures from the ocean, have a lot to teach us about how life evolved from simple to complex forms. They belong to a group of animals called Cnidaria, which are some of the earliest branching members of the animal kingdom. Scientists have been studying the starlet sea anemone, Nematostella vectensis, to understand how its external st...
AlUla, a UNESCO World Heritage Site in Saudi Arabia, is opening its doors to private investors. This move is part of the country's Vision 2030 plan to reduce dependence on oil and boost tourism. The site, which saw 300, 000 visitors last year, has big plans. By 2030, it aims to welcome 1 million visitors. To achieve this, AlUla is offering 21 projects worth 6 billio...
Aging is a natural process, but how we age can be influenced by what we put into our bodies. Enter Fatty15, a supplement that focuses on cellular health to promote longevity. It contains C15:0, a unique fatty acid that has been shown to support various aspects of health. C15:0 is not a typical omega-3 fatty acid. It is an essential fatty acid that plays a crucial ro...
Space isn't just a vast, mysterious frontier; it's also a harsh environment that can speed up how our cells age. Recent findings from a study show that spending time in space can make crucial blood and immune cells age faster than they normally would. The research team used advanced AI technology to keep an eye on changes in astronauts' stem cells during their time ...
Goat embryos face a tough journey when they're frozen for later use. Scientists wanted to find out how to keep them healthy before the big freeze. They tested three different methods to see which one worked best. First, they looked at how long embryos were kept in a dish at body temperature. Some were kept for just 3 hours, while others stayed for 6 to 8 hours. The ...
Scientists have found a key protein in the sticky stuff that holds together sludge granules in seawater. This protein might be the reason these granules stay strong and can remove phosphate from water. The granules were grown in a special reactor using seawater and acetate, a common carbon source. The main microbe in these granules was "Candidatus Accumulibacter, " w...
Aging is a complex process. It's not just about time passing. It's about what happens inside our cells. Telomeres, the protective caps on our chromosomes, get shorter every time our cells divide. Eventually, this leads to cellular senescence, a state where cells stop functioning properly. This is a big part of why we age and develop age-related diseases. Telomerase ...
