First Sellafield fuel pond sludge encapsulated

World Nuclear News - Mon, 02/20/2017 - 09:08
Drums of radioactive sludge from Sellafield's Pile Fuel Storage Pond - the world's oldest nuclear storage pond - have been processed in the site's encapsulation plant for the first time. The waste is now ready for long-term disposal.

India creates medical supplies from nuclear waste

World Nuclear News - Mon, 02/20/2017 - 08:43
Scientists in India are using materials recovered from radioactive waste to protect babies and vulnerable patients from adverse reactions to blood transfusion. A production line at the Bhabha Atomic Research Centre in Trombay creates medical products based on caesium-137 instead of the usual cobalt-60, with a range of benefits.

Biogeochemistry: Deep ocean iron balance

Nature Geoscience Advanced Online - Mon, 02/20/2017 - 00:00

Author: William B. Homoky

Dissolved iron is mysteriously pervasive in deep ocean hydrothermal plumes. An analysis of gas, metals and particles from a 4,000 km plume transect suggests that dissolved iron is maintained by rapid and reversible exchanges with sinking particles.

Planetary science: A nickel for your planet's thoughts

Author: Paolo A. Sossi

Variability of iron isotopes among planetary bodies may reflect their accretion or differentiation histories. Experiments suggest nickel may be the ingredient controlling iron isotope signatures, supporting fractionation during core formation.

Morano hails EPA’s New Chief Pruitt: No more ‘ridiculous statements about how EPA regs will somehow alter global temps’

Climate Depot - Sun, 02/19/2017 - 21:29
By MICHAEL BIESECKER Friday, February 17, 2017 08:39PM WASHINGTON — The Senate confirmed Scott Pruitt to lead the Environmental Protection Agency on Friday. Pruitt was sworn in later Friday by Supreme Court Justice Samuel Alito. In six years as Oklahoma’s attorney general, Pruitt filed 14 lawsuits challenging EPA regulations that included limits on carbon emissions [...]

CO2 emissions ‘crashing’: Take Back Al Gore’s Nobel & Give It To Fracking Industry

EDITORIALS Take Back Al Gore’s Nobel And Give It To The Fracking Industry A hydraulic fracturing (fracking) rig is seen in Weld County, Colorado. Thanks to fracking and the natural gas it provides, U.S. output of carbon dioxide emissions is crashing.

Geometry and network connectivity govern the mechanics of stress fibers [Biophysics and Computational Biology]

PNAS Early Edition Articles - Fri, 02/17/2017 - 13:33
Actomyosin stress fibers (SFs) play key roles in driving polarized motility and generating traction forces, yet little is known about how tension borne by an individual SF is governed by SF geometry and its connectivity to other cytoskeletal elements. We now address this question by combining single-cell micropatterning with subcellular...

PLCϵ1 regulates SDF-1{alpha}-induced lymphocyte adhesion and migration to sites of inflammation [Immunology and Inflammation]

PNAS Early Edition Articles - Fri, 02/17/2017 - 13:33
Regulation of integrins is critical for lymphocyte adhesion to endothelium and migration throughout the body. Inside-out signaling to integrins is mediated by the small GTPase Ras-proximate-1 (Rap1). Using an RNA-mediated interference screen, we identified phospholipase Cε 1 (PLCε1) as a crucial regulator of stromal cell-derived factor 1 alpha (SDF-1α)-induced Rap1...

Heat shock protein that facilitates myelination of regenerating axons [Commentaries]

PNAS Early Edition Articles - Fri, 02/17/2017 - 13:33
Peripheral Nerve Regeneration It is widely recognized that neurons in the peripheral nervous system (PNS) are capable of regeneration after injury. In contrast, those neurons that are entirely located within the CNS (i.e., the brain and spinal cord) largely do not regenerate. What is often not emphasized, however, is that...

A win-win for women’s reproductive health: A nonsteroidal contraceptive and fertoprotective neoadȷuvant [Commentaries]

PNAS Early Edition Articles - Fri, 02/17/2017 - 13:33
Women are born with a complete complement of ovarian follicles for their reproductive lifetime. Each ovarian follicle contains a single oocyte, packaged in a region of the ovary that is as close to a metabolic desert as a functioning tissue can be and still survive. Little vasculature intercalates this outer...

Mitochondrial damage elicits a TCDD-inducible poly(ADP-ribose) polymerase-mediated antiviral response [Immunology and Inflammation]

PNAS Early Edition Articles - Fri, 02/17/2017 - 13:33
The innate immune system senses RNA viruses by pattern recognition receptors (PRRs) and protects the host from virus infection. PRRs mediate the production of immune modulatory factors and direct the elimination of RNA viruses. Here, we show a unique PRR that mediates antiviral response. Tetrachlorodibenzo-p-dioxin (TCDD)-inducible poly(ADP ribose) polymerase (TIPARP),...
