Protein on protein action
NMR has allowed German researchers to investigate the cooperative binding of DNA to an important protein involved in suppressing tumour growth in our bodies. The binding of p53 to DNA is regulated by protein-protein interactions through a double salt bridge, they have found. The finding suggests that this salt bridge might be crucial to protecting us from certain types of cancer and fixing it when it malfunctions could provide a new avenue for anticancer drug research. Nanoscale Study Gives New Insight Into Heat Transfer In Biological Sys

'Hash' Competition Could Help Strengthen Computer Security
NIST is planning a competition to develop one or more cryptographic 'hash' algorithms to augment and revise the current Secure Hash Standard (Federal Information Processing Standard 180-2). Low Heart Rate Variability In Depressed Patients Contributes To High M
Scientists have known for years that depression increases the risk of dying in the months after a heart attack, but they haven't understood how depression raises that risk. Now, behavioral medicine specialists at Washington University School of Medicine in St. Louis, report in the Archives of Internal Medicine that abnormal heart rate variability is partially responsible for depression's effects in heart patients.
