A restructuring of Paladin Energy's balance sheet, announced in January, will position the Australia-based uranium company to increase production rather than service its debt in response to a 'normalising' uranium market, its CEO said yesterday.
Congress Slashes Funding For NASA’s Global Warming Research Andrew Follett Energy and Science Reporter 4:11 PM 02/20/2017 The U.S. Senate passed legislation recently cutting funding for NASA’s global warming research. The House is expected to pass the bill, and President Trump will likely sign it. Supporters say it “re-balances” NASA’s budget back toward space [...]
Small amounts of Iodine-131, well below levels likely to have any effect on human health, were detected in outdoor air last month in a number of European countries. The source of the release has yet to be identified.
President Donald Trump will order the Environmental Protection Agency (EPA) to begin dismantling a regulation central to former President Barack Obama’s plan to fight global warming. A source briefed on the matter told The Washington Post one of the orders “will instruct the Environmental Protection Agency to begin rewriting the 2015 regulation that limits greenhouse-gas emissions from [...]

A consortium of small modular reactor developers and customers has issued a policy statement setting out the benefits of public-private partnerships to facilitate the commercialisation and export of US-designed SMRs.
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.
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.

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.

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.

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 [...]
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. (Bloomberg) 2/17/2017 Climate Change: U.S. output of so-called greenhouse gases continues to decline, a [...]
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...
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...
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...
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...
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),...
