Newborn neurons like to hang with the 'in' crowd

...rk to 80 percent, reinforcing the observation that using one's brain cells is the best way to optimize brain function throughout one's lifetime. ...

Students invent protective pouch to enhance cell therapy

...llow the microcapsules to escape. In lab tests using latex tubing to represent a vein, the students used ultrasound imaging to confirm that fluid can flow smoothly through the mesh and can spread the microcapsules throughout pouch. They also demonstrated that the device causes no pressure drop in the m...

New technique will produce a better chromosome map

...cells for viewing under a light microscope involve using a thumb, pencil, forceps or other instrument to maneuver and press the cells between a glass coverslip and slide. Only about 10 percent of the slides processed this way provide useable images and even those rarely offer crisp structural details, Novi...

UQ research heralds vaccine technology breakthrough

...search group has developed a "recombinant" vaccine using the existing Hepatitis B vaccine to carry the RSV peptides. "Hepatitis B surface antigen forms virus-like particles, which are the vaccine used for Hepatitis B vaccine all around the world," Professor Tindle said. "We're taking advantage of that ...

New Brandeis research sheds light on memory by erasing it

...hat happens to the CaMKII after it is attacked. By using fluorescent forms of CaMKII, it will be possible to determine whether the kinase leaves the synapse after inhibitor is applied. This provides a way to directly visualize the forgetting process and complements previous work done in Lisman's laboratory...

Molecule that destroys bone also protects it, new research shows

...for IL-17. Other researchers had shown previously, using rats and mice as animal models, that blocking the receptor for IL-17 could be an effective therapy for RA and possibly for other autoimmune diseases such as multiple sclerosis, colitis, psoriasis and lupus. The effects of an IL-17 deficiency in p...

Diminishing dinosaur steps saved by laser and laptop

...permanent and detailed record has now been created using cutting-edge equipment. Using a high-tech laser scanning system called RIEGL, researchers from The School of Earth, Atmospheric and Environmental have produced an interactive 3D model of a quarry face covered in thousands of tracks made by the lat...

DNA repair proteins monitored at double-strand break

...bout the proteins that repair DNA than is possible using the standard microscope-based approach previously used for such work." Kastan is the paper’s senior author. A deficiency in two of these repair proteins, ATM and NBS1, leads to defects in double-strand break repair by disrupting the signaling proc...

UCLA AIDS Institute researchers find a peptide that encourages HIV infection

...e way for the use of such peptides in gene therapy using HIV-based vectors as the delivery method. "Although it may seem counterintuitive to value or even study a peptide that increases the ability of HIV-1 to enter a broad range of human cells, retroviral vectors are currently being explored as vehicle...
