A Dutch study indicates that just one ten-second kiss may pass on as many as 80 million bacteria. Dutch scientists found that couples who kissed nine times a day were more likely to share saliva bacteria. Previous studies indicate that the human mouth may host over 700 different bacterial species. The new research shows that […]

A recent imaging study questions long-held beliefs about how hair grows and may open the door to new hair-loss treatments. Scientists have found that human hair doesn’t grow by being pushed up from the root. Rather, it is drawn along by forces from a newly identified network of moving cells. This discovery challenges long-standing biological

Researchers investigated the diet and plastic consumption of green sea turtles living in the waters near the Ogasawara Islands, Japan, finding plastics in 7 out of 10 turtles studied. By combining genetic, isotopic, and plastic analyses, they inferred that the plastics had come from regions outside the turtles’ usual migratory routes, highlighting the impact of

Italy is emerging as a leader in technological innovation through the development of 3D-printed food. At ENEA’s research laboratory in Oricola, scientists are converting plant cells and food waste into so-called “edible inks,” which are then used to produce nutrient-rich cereal bars, confectionery, and small honey spheres. Main features of the technology: Cell-Based Cultivation in

Solar cells, which produce electricity from sunlight, are already contributing to lower fossil fuel emissions in numerous countries around the world. Recently, energy engineers have been exploring alternatives to silicon to create solar cells that are more efficient, long-lasting, and cost-effective. These materials include perovskites, especially halide perovskites, which have a distinctive ABX₃ crystal structure

Scientists at Touro University Nevada have found that small blood particles, known as extracellular vesicles (EVs), play a key role in transporting certain hormones throughout the body. Physical exercise can enhance this process. Key Players in Hormone Transport and Exercise Effects The study, published in Proceedings of the National Academy of Sciences, provides new insights

Washington State University researchers found a way to block a key viral protein, stopping viruses from entering cells.. This breakthrough suggests a promising new avenue for developing future antiviral treatments. Published in Nanoscale, the study explored blocking a key molecular interaction herpes viruses use to invade cells, in a collaboration between the School of Mechanical
AI Discovered a Method to Block a Virus Before it can Enter Cells Read More »
A research team from Switzerland and Japan has closely examined how the virus behaves. Using a self-developed microscopy technique, the scientists can focus on the outer surface of human cells in a Petri dish, allowing them to observe in real time the precise moment an influenza virus enters a living cell. Led by Yohei Yamauchi,

Scientists have found that avian flu viruses carry a gene that makes them unusually tolerant to heat, rendering one of our key immune defenses—fever—largely ineffective. Instead of slowing the infection, higher temperatures actually help these viruses reproduce.

A human chest, initially the size of a room, fills your entire view. With a few commands, you shrink it to a tiny speck, then restore it to life-size and lay it flat. You peel away the skin and layers of muscle and organs, while informative text floats in the air, projected by your headset
