Cellular and Molecular Mechanisms of Peripheral Nerve Regeneration
Cellular and molecular mechanisms of peripheral nerve regeneration - In this video abstract, the authors use the in vivo imaging to examine if and how regenerating axons return to their original targe...
Memory Enhancement by Targeting NR2B Cell Surface Regulation
Many neurological disorders, such as Alzheimer's disease, are characterized by learning and memory deficits, for which cognitive enhancement is considered a valid treatment strategy. Plattner and coll...
Visual control of octopus arm movements - Octopuses are known among invertebrates for their sophisticated behavior and the task they face of controlling eight flexible arms is a daunting one. As expla...
Homologous chromosomes find each other and align correctly during meiosis with the help of the cytoskeleton, new work by Dernburg and colleagues shows. Watch......
Sensing DNA Damage, ATP Orders an Mre11-Rad50 Clamp Down
Sensing DNA Damage, ATP Orders an Mre11-Rad50 Clamp Down - By trapping Mre11-Rad50 in mulitple states, Karl-Peter Hopfner and colleagues discover that Mre11-Rad50 transiently assembles into an ATP-con...
Connecting Parkinson's Disease Gene Functions - This video describes the identification of functional interactions between Parkinson's disease genes VPS35, EIF4G1, and alpha-synuclein. Aaron Gitler an...
