Supercomputers fire lasers to shoot gamma ray beam

Supercomputer simulations have shown scientists a new way to generate controlled beam of gamma rays from lasers. Nearly one million CPU hours on Stampede and Lonestar HPC systems were needed for the particle-in-cell simulation. The Texas Petawatt Laser will use the simulations to guide experimental verification later in 2016. Gamma ray production would make possible basic science research and benefit society through brain imaging, cancer therapy, and anti-terrorist cargo scanning.

In this study, we did not observe significant age-dependent upregulation of the prominent SASP cytokine Il6 in any tissue, although an upward trend was observed that was consistent in magnitude with previous observations in the heart and kidney. This modest age-related upward trend could be explained by a previous report which demonstrated that senescent cell-secreted IL-6 acts in an autocrine manner, reinforcing the senescent state, rather than inducing senescence or promoting dysfunction in neighboring cells. The decreased expression of Il6 with age we observed in the hypothalamus could be indicative of a lack or ...

Current therapy for malignant brain tumors, such as glioblastoma multiforme (GBM), is insufficient, with nearly universal recurrence. Available drug therapies are unsuccessful because they fail to penetrate through the region of the brain containing tumor cells and they fail to kill the cells most responsible for tumor development and therapy resistance, brain cancer stem cells (BCSCs). To address these challenges, we combined two advances in technology: 1) brain-penetrating polymeric nanoparticles that can be loaded with drugs and are optimized for intracranial convection-enhanced delivery (CED); and 2) re-purposed, FDA-a...

This study included 647 patients 80 to 106 years of age who had audiometric evaluations at an academic medical center (141 had multiple audiograms). The degree of hearing loss was compared across the following age brackets: 80 to 84 years, 85 to 89 years, 90 to 94 years, and 95 years and older. From an individual perspective, the rate of hearing decrease between 2 audiograms was compared with age. The researchers found that changes in hearing among age brackets were higher during the 10th decade of life than the 9th decade at all frequencies for all the patients (average age, 90 years). Correspondingly, the annual rate of ...

ConclusionsWe developed an MRgFUS platform for small-animal treatments that robustly delivers accurate, precise, and controllable sonications over extended time periods. This system is an open source and could increase the availability of low-cost small-animal systems to interdisciplinary researchers seeking to develop new MRgFUS applications and technology.

WebMD wasn't a research option when Ivy Brown was diagnosed with Hodgkin's lymphoma in 1974, so her mother looked up her 12-year-old daughter's condition the old-fashioned way, in a hardcover medical volume. "It just said 'fatal,'" Brown explained. Having moved the family to London a month earlier, Brown's parents were still trying to liaise with her pediatrician in the U.S. "My father told me recently that he was sleeping with the phone on his stomach because of the time change," she said. "They were as scared as you can be when you have a child who you think you might lose," Brown explained....

We examined the engraftment and differentiation of alkaline phosphatase-positive NSCs expanded from the postnatal subventricular zone (SVZ), 3 months after grafting into the intact young or aged rat hippocampus. Graft-derived cells engrafted robustly into both young and aged hippocampi. Although most graft-derived cells pervasively migrated into different hippocampal layers, the graft cores endured and contained graft-derived neurons. The results demonstrate that advanced age of the host at the time of grafting has no major adverse effects on engraftment, migration, and differentiation of grafted subventricular zone...

This study offers one useful data point, as the authors describe a genetic alteration that can boost the supply of new immune cells in old mice. The decline in that supply with age is one of the factors leading to poor immune function - and that means more than just vulnerability to infections, as the immune system is also responsible for destroying potentially cancerous and senescent cells, as well as clearing out forms of damaged proteins and unwanted metabolic waste. Various possibilities for increasing the number of new immune cells already exist in principle, such as regenerating the thymus, or cell therapies in which...
