Disruptions in the supply of energy to cells can cause a number of serious diseases, but they also appear to be linked to aging. More research on mitochondrial function is needed to find future treatments. A new study with researchers from the Karolinska Institutet shows how an important molecule in the mitochondria affects their function […]
The Toxin-Antitoxin Function Boosts Antibiotic Resistance Research – ScienceDaily
Thomas Wood, Endowed Chair of Biotechnology and Professor of Chemical Engineering at Penn State College of Engineering, has known that toxin-antitoxin (TA) systems negatively control plasmid replication. Plasmids, or pieces of extrachromosomal DNA, allow bacteria to evade antibiotics, which means that the antibiotics cannot stop bacterial infection. The presence or absence of plasmids affects a […]
How did the function of the forelegs change when vertebrates acquired limbs and went ashore? – ScienceDaily
When tetrapods (four-limbed vertebrates) began moving from water to land about 390 million years ago, they sparked the rise of lizards, birds, mammals, and all land animals that exist today, including humans and some aquatic animals like whales and dolphins. The earliest tetrapods come from their fish ancestors in the Devonian period and are more […]
