Many diseases can be successfully treated in the simple environment of a cell culture dish, but to successfully treat real people, the drug agent has to take a journey through the infinitely more complex environment within our bodies and…

Eating lots of fats increases the risk of metabolic disorders, but the mechanisms behind the problem have not been well understood. Now, University of California, Irvine biologists have made a key finding about how to ward off harmful…

One of the most important classes of human enzymes are protein kinases -- signaling molecules that regulate nearly all cellular activities, including growth, cell division, and metabolism. Dysfunction in these cellular pathways can lead to…

Enzymes, which are crucial to controlling how cells replicate in the human body, could be the very ingredient that encourages DNA to spontaneously mutate -- causing potentially permanent genetic errors, according to new research from the…

In response to a high-competition environment, Trinidadian killifish evolve larger brains, increasing their fitness and survival rates, according to a new study in Ecology Letters by biologists at The University of Texas at Arlington. The…

Imagine being stuck in close quarters with your coworkers 24 hours a day, far away from your home, under conditions that are stressful and unfamiliar. Scientists have a name for that: fieldwork. Doing research outside of the lab is…

About 70 percent of all human proteins include at least one sequence consisting of a single amino acid repeated many times, with a few other amino acids sprinkled in. These "low-complexity regions" are also found in most other organisms.…

ANI Washington, September 2Scientists have managed to generate a new type of human cell in the lab using stem cells. The new cells closely resemble…

Professor Vincent Pasque and his team at KU Leuven have managed to generate a new type of human cell in the lab using stem cells. The new cells closely resemble their natural counterparts in early human embryos. As a result, researchers can…
