About 1,500 Adelaide residents and businesses are being told not to use groundwater because of contamination from uranium from a former mining laboratory and degreasing chemicals from nearby factories.

Mary Kathleen's shuttered uranium mine is bright blue, incredibly Instagram-worthy, radioactive and Queensland's latest hotspot.

A rare copy of the nearly 40-year-old documentary Dirt Cheap, which details the early resistance against uranium mining in Kakadu National Park, is rediscovered in Darwin.

(United States Supreme Court) - Held that the federal Atomic Energy Act did not preempt a Virginia law prohibiting uranium mining. While six justices agreed that the state ban on uranium mining was not preempted, they divided on broader questions concerning statutory interpretation and preemption doctrine, and thus were unable to agree on the rationale for the decision. Justice Gorsuch delivered a plurality opinion, and several justices concurred in the judgment only.

(United States Seventh Circuit) - Affirmed. The subject of a legal judgment sought to pursue the doctrine of estoppel to compel their insurer to pay out on the judgment against them from a decade before the policy's active date. They suffered no prejudice from the insurer's action and their case was dismissed.

(United States Seventh Circuit) - Affirmed. An insurer had to replace the siding on an entire building whose south and west sides were damaged by a storm because the old siding was no longer available and the new siding didn't match.

(California Court of Appeal) - Reversed. Plaintiffs, employees of Defendant, signed an agreement with Defendant requiring binding arbitration of employment disputes after the complaint was filed. The trial court denied Defendant’s motion to compel arbitration agreeing with Plaintiff that the arbitration agreement referred to future claims not the past ones brought by Plaintiff against Defendant. The appeals court disagreed stating that the agreement to arbitrate was clear and there was no qualifying language as to past or future events.

(United States Ninth Circuit) - In a trade dress action, the district court's grant of summary judgment to defendant is reversed where there is a genuine fact issue as to whether plaintiff's manner for presenting results in its urine test report was functional under the Lanham Act.

Justice Gorsuch delivered a plurality opinion, and several justices concurred in the judgment only.

(California Court of Appeal) - Affirmed. Plaintiff challenged a trial court ruling that a proposed development failed to comply with the California Environmental Quality Act. The appeals court found that the trial court did not err in concluding that that the project failed to comply with the CEQA requirement of an accurate, stable, and finite project description.

(United States First Circuit) - In a case that involves a man, his emotional support dog, and a condominium association's 'no pets' rule, alleging disability discrimination under the Fair Housing Act, 42 U.S.C. sections 3601-3619, the condominium association's petition for judicial review of a final order of the Secretary of the United States Department of Housing and Urban Development is denied and the Secretary's cross-petition for enforcement of his order is granted where substantial evidence supports the Secretary's finding that the Association's refusal to allow the former condo owner to keep an emotional support dog in his condominium unit as a reasonable accommodation for his disability was unlawful.

This week on the UK Tech Weekly Podcast our host Scott Carey talks to Macworld editor David Price about the ever-controversial Alex Jones and why the big tech companies are finally stepping up their efforts to ban him from their platforms. Editors note: we recorded this on Thursday before Twitter finally started to take some measures against Jones, without outright banning him.

Next our resident phone nerd and consumer tech editor at Tech Advisor Henry Burrell talks about the upcoming Samsung Galaxy Note 9, the latest iPhone X rumours and how Apple and Google are trying to make you use your phone less.

Lastly Techworld editor Charlotte Jee takes us on a trip down memory lane to talk about the utopian vision of the Millennium Experience, how it reflected the values of a New Labour government and its legacy.

Segmentation of cardiac images, particularly late gadolinium-enhanced magnetic resonance imaging (LGE-MRI) widely used for visualizing diseased cardiac structures, is a crucial first step for clinical diagnosis and treatment. However, direct segmentation of LGE-MRIs is challenging due to its attenuated contrast. Since most clinical studies have relied on manual and labor-intensive approaches, automatic methods are of high interest, particularly optimized machine learning approaches. To address this, we organized the "2018 Left Atrium Segmentation Challenge" using 154 3D LGE-MRIs, currently the world's largest cardiac LGE-MRI dataset, and associated labels of the left atrium segmented by three medical experts, ultimately attracting the participation of 27 international teams. In this paper, extensive analysis of the submitted algorithms using technical and biological metrics was performed by undergoing subgroup analysis and conducting hyper-parameter analysis, offering an overall picture of the major design choices of convolutional neural networks (CNNs) and practical considerations for achieving state-of-the-art left atrium segmentation. Results show the top method achieved a dice score of 93.2% and a mean surface to a surface distance of 0.7 mm, significantly outperforming prior state-of-the-art. Particularly, our analysis demonstrated that double, sequentially used CNNs, in which a first CNN is used for automatic region-of-interest localization and a subsequent CNN is used for refined regional segmentation, achieved far superior results than traditional methods and pipelines containing single CNNs. This large-scale benchmarking study makes a significant step towards much-improved segmentation methods for cardiac LGE-MRIs, and will serve as an important benchmark for evaluating and comparing the future works in the field.

Delayed meconium passage impairs gastrointestinal function in premature infants. No intervention has been identified that accelerates meconium passage sufficiently. Gastrografin is an osmotic contrast agent used for radiologic examination of the bowel or for conservative treatment of uncomplicated meconium ileus.

Gastrografin did not accelerate complete meconium evacuation but stimulated gastrointestinal motility in a randomized, placebo-controlled trial in premature infants. Application shortened the time to full enteral feedings and hospital stay but was associated with necrotizing enterocolitis as a possible adverse event. (Read the full article)

BACKGROUND AND OBJECTIVES:

The albuterol dropper bottle used to prepare solutions for continuous nebulization contains the preservative benzalkonium chloride (BAC). BAC, by itself, has been shown to cause bronchospasm. We hypothesized that BAC would decrease the therapeutic efficacy of albuterol in patients with acute asthma exacerbations.

The nitrate transport accessory protein OsNAR2 plays a critical role in root-growth responses to nitrate and nitrate acquisition in rice (Oryza sativa). In this study, a pull-down assay combined with yeast two-hybrid and coimmunoprecipitation analyses revealed that OsNAR2.1 interacts with OsNIT1 and OsNIT2. Moreover, an in vitro nitrilase activity assay indicated that indole-3-acetonitrile (IAN) is hydrolyzed to indole-3-acetic acid (IAA) by OsNIT1, the activity of which was enhanced 3- to 4-fold by OsNIT2 and in excess of 5- to 8-fold by OsNAR2.1. Knockout (KO) of OsNAR2.1 was accompanied by repressed expression of both OsNIT1 and OsNIT2, whereas KO of OsNIT1 and OsNIT2 in the osnit1 and osnit2 mutant lines did not affect expression of OsNAR2.1 or the root nitrate acquisition rate. osnit1 and osnit2 displayed decreased primary root length and lateral root density. Double KO of OsNAR2.1 and OsNIT2 caused further decreases in lateral root density under nitrate supply. Ammonium supply repressed OsNAR2.1 expression whereas it upregulated OsNIT1 and OsNIT2 expression. Both osnit1 and osnit2 showed root growth hypersensitivity to external ammonium; however, less root growth sensitivity to external IAN, higher expression of three IAA-amido synthetase genes, and a lower rate of ³H-IAA movement toward the roots were observed. Taken together, we conclude that the interaction of OsNIT1 and OsNIT2 activated by OsNAR2.1 and nitrogen supply is essential for maintaining root growth possibly via altering the IAA ratio of free to conjugate forms and facilitating its transportation.
