A multi-institutional team of scientists has gained important new knowledge about the regulatory role played in Alzheimer’s disease by Pin1, a protein that coaxes other proteins into untwisting. The research is published in the July 31 issue of Nature.
The team of researchers, including a group from the Department of Human Genetics at Emory University School of Medicine, examined slices of brain and found an inverse relationship between the abundance of Pin1 and both the susceptibility of neurons to degenerative damage and the amount of protein tangles. They also found that mice with an artificial disruption of Pin1 develop a neurodegenerative disease that resembles Alzheimer’s.
Lead authors are Drs. Yih-cherng Liou, Anyang Sun, and Kun Ping Lu from Harvard Medical School. Xiaojiang Li, PhD and Zhao-Xue Yu, PhD from Emory School of Medicine studied the degeneration in the brains of Pin1-deficient mice using electron microscopy and immunogold staining. Scientists from the University of Kentucky, the Salk Institute, and Tufts University also contributed to the study.

Since their experimental discovery, magnetic skyrmions - tiny magnetic knots - have moved into the focus of research. Scientists from Hamburg and Kiel have now been able to show that individual magnetic skyrmions with a diameter of only a few nanometres can be stabilised in magnetic metal films even without an external magnetic field. They report on their discovery in the journal Nature Communications.
The existence of magnetic skyrmions as particle-like objects was predicted 30 years ago by theoretical physicists, but could only be proven experimentally in...
Theoretical physicists at Trinity College Dublin are among an international collaboration that has built the world's smallest engine - which, as a single calcium ion, is approximately ten billion times smaller than a car engine.
Work performed by Professor John Goold's QuSys group in Trinity's School of Physics describes the science behind this tiny motor.
Together with the University of Innsbruck, the ETH Zurich and Interactive Fully Electrical Vehicles SRL, Infineon Austria is researching specific questions on the commercial use of quantum computers. With new innovations in design and manufacturing, the partners from universities and industry want to develop affordable components for quantum computers.
Ion traps have proven to be a very successful technology for the control and manipulation of quantum particles. Today, they form the heart of the first...
Experimental progress towards engineering quantized gauge fields coupled to ultracold matter promises a versatile platform to tackle problems ranging from condensed-matter to high-energy physics
The interaction between fields and matter is a recurring theme throughout physics. Classical cases such as the trajectories of one celestial body moving in the...
Soft robots have a distinct advantage over their rigid forebears: they can adapt to complex environments, handle fragile objects and interact safely with humans. Made from silicone, rubber or other stretchable polymers, they are ideal for use in rehabilitation exoskeletons and robotic clothing. Soft bio-inspired robots could one day be deployed to explore remote or dangerous environments.
Most soft robots are actuated by rigid, noisy pumps that push fluids into the machines' moving parts. Because they are connected to these bulky pumps by tubes,...
