Our DNA and its architecture are duplicated every time our cells divide. Histone proteins are key building blocks of this architecture and contain crucial information that regulates our genes. Danish researchers show how an enzyme controls reliable and high-speed delivery of histones to DNA copying hubs in our cells. This shuttling mechanism is crucial to maintain normal function of our genes and prevent disease. The results are published in the journal Nature Communications.

Research has shown that dark chocolate is good for cardiovascular health. A study published in The FASEB Journal indicates that dark chocolate improves cardiovascular health by helping to keep arteries flexible and preventing white blood cells from getting stuck to blood vessel walls. This helps to reduce blood pressure and increase blood flow to the heart and brain...

Berkeley Lab scientists and other researchers are attempting to discover a way to stop Staph infections by studying how Staphylococcus aureus bacteria adhere to surfaces. These bacteria can adhere to medical equipment and cause serious illness if they enter the body and cause an infection. Some strains, such as methicillin-resistant Staphylococcus aureus (MRSA), are even more threatening as they have developed resistance to antibiotics....
