Scientists have figured out how to make tiny arteries in the lab that work like the real thing. They did this by copying how arteries stretch and move in the body. This is a big deal because it helps them study arteries and test new medicines. The team used two types of human cells: one from vein l
Bacteria are getting a high-tech makeover. Scientists are finding new ways to tweak their DNA with precision. This isn't just about changing a few genes. It's about completely redesigning these tiny organisms to do new things. For a long time, scientists have relied on a process called homologous r
MXenes are a type of two-dimensional material that scientists are really interested in. They are made up of layers of metal and carbon or nitrogen atoms. The space between these layers is what makes MXenes special. This space can change depending on what atoms are on the surface of the layers. Scie
Piezoelectric materials are special because they can turn mechanical energy into electrical energy and vice versa. Now, scientists are making these materials clear, like glass, which opens up new possibilities. These clear materials can be used in things like medical devices, acoustic systems, and e
In Sweden, many young adult dogs face joint problems. Hip and elbow dysplasia (HD and ED) are two serious conditions that affect dogs' mobility. These issues are common in various breeds. A recent study aimed to find out how widespread these problems are and if they are linked. The study looked at
Heart disease is a major health concern, and scientists are constantly searching for better ways to predict and prevent it. One recent study used a special type of scan called CCTA to examine how blood moves through the heart's arteries. This scan provides a highly detailed view of the heart's blood
Lithium-sulfur batteries hold great promise, but they have a big problem. The shuttle effect and slow sulfur conversion cause them to wear out quickly. To tackle this, scientists created a smart sulfur host called VGS@MoC/NCNF. This host is made of nitrogen-doped carbon nanofibers coated with graphe
Magnesium is a hot topic in medical tech. It's being looked at for making stents that dissolve over time. But there's a catch. Magnesium corrodes too fast. To slow this down, scientists mix it with other metals and add special coatings. This isn't just about lasting longer. It's also about how the b
In the hot, bubbling waters of Yellowstone, something unexpected is happening. Bacteria, usually known for sticking to their own kind, are mixing it up. This isn't just a one-time thing. It's been going on for thousands of years. Scientists looked at over 300 single-cell genomes of these bacteria. T
Alcohol doesn't just cause a headache or dry mouth the next day. It can also lead to urgent bathroom trips, a problem sometimes called "booze butt. " Doctors say alcohol can irritate the digestive tract, change gut bacteria, and mess with how the intestines absorb water. Dr. Leybelis Padilla, a gut
