New methodology helps investigate unfolding of DNA

NYU Langone Medical Center researchers have developed a powerful new method to investigate the discrete steps necessary to turn on individual genes and examine how the process goes wrong in cancer and other diseases. The finding, based on seven years of research and described in the April 9 issue of Molecular Cell, allows scientists to investigate the unfolding of DNA, a process required for gene activation.

DIS serves as marker for new methods to diagnose NERD

Gastroesophageal reflux disease is an important public health problem which is extremely common nowadays. Symptoms of GERD arise from the exposure of increased acid gastric contents into the lower part of the esophageal mucosa. Most patients with GERD have NERD with invisible mucosal damages under endoscopy.

Caddisfly silk and sandcastle worm glue: Potential adhesives during surgery

Like silkworm moths, butterflies and spiders, caddisfly larvae spin silk, but they do so underwater instead on dry land. Now, University of Utah researchers have discovered why the fly's silk is sticky when wet and how that may make it valuable as an adhesive tape during surgery.

New non-neurotoxic treatment for head lice in children

A new non-neurotoxic treatment for head lice has been found to have an average of 91.2% treatment success rate after one week, and to be safe in humans from six months of age and up. This is the finding of a study published today in Pediatric Dermatology.

Kinesin protein motor shuttles cargo within cells and helps cells divide by rocking like a seesaw

Life's smallest motor, a protein that shuttles cargo within cells and helps cells divide, does so by rocking up and down like a seesaw, according to research conducted by scientists at the U.S. Department of Energy's Lawrence Berkeley National Laboratory and Brandeis University.

3D images of synapsis between neurons through electron cryotomography

A team of researchers from the Max Planck Institute of Biochemistry, in Germany, led by the Spanish physicist Rub-n Fern-ndez-Busnadiego, has managed to obtain 3D images of the vesicles and filaments involved in communication between neurons. The method is based on a novel technique in electron microscopy, which cools cells so quickly that their biological structures can be frozen while fully active.

Studies examine interaction of ribosome with molecular partners

Two new studies reveal in unprecedented detail how the ribosome interacts with other molecules to assemble new proteins and guide them toward their destination in biological cells. The studies used molecular dynamics flexible fitting (MDFF) to examine the interaction of the ribosome with two prominent molecular partners.

New non-toxic and environmentally friendly method for making tiny nanorods of zinc oxide

A non-toxic and environmentally friendly way to make tiny nanorods of zinc oxide has been developed for the first time by researchers in Saudi Arabia. The approach, described in the current issue of the International Journal of Nanoparticles, could allow the nanorods to be used safely in medical and for other applications.

Endocannabinoids found to spread and prolong pain

Imagine that you're working on your back porch, hammering in a nail. Suddenly you slip and hit your thumb instead - hard. The pain is incredibly intense, but it only lasts a moment. After a few seconds (and a few unprintable words) you're ready to start hammering again.
