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.

The world's highest gain high power laser amplifier - by many orders of magnitude - has been developed in research led at the University of Strathclyde.
The researchers demonstrated the feasibility of using plasma to amplify short laser pulses of picojoule-level energy up to 100 millijoules, which is a 'gain'...
Staphylococcus aureus is a feared pathogen (MRSA, multi-resistant S. aureus) due to frequent resistances against many antibiotics, especially in hospital infections. Researchers at the Paul-Ehrlich-Institut have identified immunological processes that prevent a successful immune response directed against the pathogenic agent. The delivery of bacterial proteins with RNA adjuvant or messenger RNA (mRNA) into immune cells allows the re-direction of the immune response towards an active defense against S. aureus. This could be of significant importance for the development of an effective vaccine. PLOS Pathogens has published these research results online on 25 May 2017.
Staphylococcus aureus (S. aureus) is a bacterium that colonizes by far more than half of the skin and the mucosa of adults, usually without causing infections....
Physicists from the University of Würzburg are capable of generating identical looking single light particles at the push of a button. Two new studies now demonstrate the potential this method holds.
The quantum computer has fuelled the imagination of scientists for decades: It is based on fundamentally different phenomena than a conventional computer....
An international team of physicists has monitored the scattering behaviour of electrons in a non-conducting material in real-time. Their insights could be beneficial for radiotherapy.
We can refer to electrons in non-conducting materials as ‘sluggish’. Typically, they remain fixed in a location, deep inside an atomic composite. It is hence...
Two-dimensional magnetic structures are regarded as a promising material for new types of data storage, since the magnetic properties of individual molecular building blocks can be investigated and modified. For the first time, researchers have now produced a wafer-thin ferrimagnet, in which molecules with different magnetic centers arrange themselves on a gold surface to form a checkerboard pattern. Scientists at the Swiss Nanoscience Institute at the University of Basel and the Paul Scherrer Institute published their findings in the journal Nature Communications.
Ferrimagnets are composed of two centers which are magnetized at different strengths and point in opposing directions. Two-dimensional, quasi-flat ferrimagnets...
