A new mouse model developed by Harvard Medical School researchers and reported in the October 30 Neuron may allow scientists for the first time to spotlight two key proteins in a living animal and see how they contribute to the neuronal death and atrophy found in neurodegenerative diseases. The two proteins are dubbed p25 and cyclin-dependent kinase 5 (Cdk5).
"This is an excellent animal model for any therapeutic approach toward p25 and its link to Alzheimers and similar neurodegenerative diseases," says Li-Huei Tsai, HMS professor of pathology and Howard Hughes Medical Institute associate investigator, the studys lead author. "We know that p25 causes neurodegeneration, and we want to figure out how that mechanism works."
The new model is the latest in Cdk5 research from the lab of Li-Huei Tsai. Over the past nine years, Tsai and her colleagues have defined many of Cdk5s functions and noted the role its usual regulator p35 plays in orienting neuronal migration and growth. Their latest challenge is deciphering how Cdk5 and the pernicious regulator p25 lead to neurodegenerative diseases.

Using ultrafast flashes of laser and x-ray radiation, scientists at the Max Planck Institute of Quantum Optics (Garching, Germany) took snapshots of the briefest electron motion inside a solid material to date. The electron motion lasted only 750 billionths of the billionth of a second before it fainted, setting a new record of human capability to capture ultrafast processes inside solids!
When x-rays shine onto solid materials or large molecules, an electron is pushed away from its original place near the nucleus of the atom, leaving a hole...
For the first time, physicists have successfully imaged spiral magnetic ordering in a multiferroic material. These materials are considered highly promising candidates for future data storage media. The researchers were able to prove their findings using unique quantum sensors that were developed at Basel University and that can analyze electromagnetic fields on the nanometer scale. The results – obtained by scientists from the University of Basel’s Department of Physics, the Swiss Nanoscience Institute, the University of Montpellier and several laboratories from University Paris-Saclay – were recently published in the journal Nature.
Multiferroics are materials that simultaneously react to electric and magnetic fields. These two properties are rarely found together, and their combined...
