In their natural environment bacteria develop by forming communities of micro-organisms called biofilms that afford them greater resistance.These biofilms on farms and premises where food is processed lead to considerable economic losses besides being a potential source of contamination and...
Researchers from the University of Wisconsin-Milwaukee (UWM) have identified mechanisms in the brain responsible for regulating cocaine-seeking behavior, providing an avenue for drug development that could greatly reduce the high relapse rate in cocaine addiction. The research reveals that...
A study by scientists from the Motor Neuron Center at Columbia University Medical Center (CUMC) suggests that spinal muscular atrophy (SMA), a genetic neuromuscular disease in infants and children, results primarily from motor circuit dysfunction, not motor neuron or muscle cell dysfunction, as...
Researchers from IMIM, Hospital del Mar Medical Research Institute, have succeeded in determining the function of a new variant of enzyme IKKalpha (IKKα) to activate some of the genes taking part in the tumor progressions of colorectal cancer. In the future, this fact will make it possible to...
An ancient heart drug that's inspired the work of herbalists and poets for centuries may treat a condition that plagues millions of overstressed and overweight Americans today. Since the 13th century, the herb Foxglove has been used to cleanse wounds and its dried leaves were brewed by Native...
Researchers at the University of Leeds have found a previously unknown mechanism through which pain is signalled by nerve cells - a discovery that could explain the current failings in the drug development process for painkillers and which may offer opportunities for a new approach...

Researchers in the University of Leicester's Department of Cell Physiology and Pharmacology have identified a cellular mechanism that could underlie the development of tinnitus following exposure to loud noises. The discovery could lead to novel tinnitus treatments, and investigations into...
The latest Perspectives in General Physiology series examines the mechanisms of visual, aural, olfactory, and tactile processes that inform us about the environment. The series appears in the September 2011 issue of the Journal of General Physiology. Everything that mammals perceive about the...
Nuclear pores are the primary gatekeepers mediating communication between a cell's nucleus and its cytoplasm. Recently these large multiprotein transport channels have also been shown to play an essential role in developmental gene regulation. Despite the critical role in nuclear function...
Baseline prostate-specific antigen (PSA) and prostate volume can be valuable predictors of treatment success when considering botulinum toxin-A (BoNT-A or Botox®) therapy for the treatment of lower urinary tract symptoms (LUTS), according to a new study presented at the 105th Annual Meeting of...
Discuss the different mechanisms of producing variation in meiosis. Include during which phase these mechanisms take place, and how different gametes could possibly be produced if the diploid number of the organism is 16.
Help me out! I cannot do complicated questions like this, please help...
I want to design and make a watch casing at school with Solidworks (3D modelling program) and I obviously can't start without measurements. I'm wondering whether it is possible to buy Analog - or if need be, digital - watch mechanisms which I can simply place inside the watch casing. Does anyone...
