    أصدرت المحكمة العليا بكندا في 30 سبتمبر 2011 أمراً للحكومة الكندية بمواصلة إعفاء مراكز حقن العقاقير المخدرة الخاضعة للرقابة في مدينة فانكوفر من القوانين الجنائية الكندية الخاصة بالعقاقير. لقد استمر عمل هذه العيادة التي تضاربت حولها الآراء، والمعروفة باسم Insite ، لمدة ثماني سنوات في أكثر الأحياء التي تعاني من المشاكل الاجتماعية والتحديات الاقتصادية بسبب الإدمان على المخدرات غير المشروعة. ويعد مركز Insite من المراكز الأولى من نوعها في أمريكا الشمالية، بالرغم من استمرار عمل مراكز حقن المخدرات الخاضعة للرقابة في أوروبا وأستراليا. في هذه المقالة، نستعرض ما أقرته المحكمة بناءً على النتائج الوقائعية لهذه العيادة والأساس الدستوري الذي استند إليه الرفض القضائي لسياسة الحكومة الصحية والجنائية. كما نناقش الآثار المترتبة على هذا القرار بالنسبة إلى المراكز المماثلة في جميع أنحاء كنداOn September 30, 2011, the Supreme Court of Canada ordered the government of Canada to continue to exempt Vancouver's supervised narcotic injection facility from Canada's criminal drug laws. The controversial clinic, known as Insite, had operated for eight years in one of the country's most socially troubled and economically challenged neighbourhoods struggling with addictions to illegal drugs. Insite was the first of its kind in North America, although supervised drug injection facilities continue in Europe and Australia. In this article we describe what the court accepted as the factual outcomes of this clinic and the constitutional basis for this judicial rejection of government health and criminal policy. We also consider the implications of this decision for similar facilities across Canada

    Measurement of the mass difference and the binding energy of the hypertriton and antihypertriton

    According to the CPT theorem, which states that the combined operation of charge conjugation, parity transformation and time reversal must be conserved, particles and their antiparticles should have the same mass and lifetime but opposite charge and magnetic moment. Here, we test CPT symmetry in a nucleus containing a strange quark, more specifically in the hypertriton. This hypernucleus is the lightest one yet discovered and consists of a proton, a neutron, and a Λ\Lambda hyperon. With data recorded by the STAR detector{\cite{TPC,HFT,TOF}} at the Relativistic Heavy Ion Collider, we measure the Λ\Lambda hyperon binding energy BΛB_{\Lambda} for the hypertriton, and find that it differs from the widely used value{\cite{B_1973}} and from predictions{\cite{2019_weak, 1995_weak, 2002_weak, 2014_weak}}, where the hypertriton is treated as a weakly bound system. Our results place stringent constraints on the hyperon-nucleon interaction{\cite{Hammer2002, STAR-antiH3L}}, and have implications for understanding neutron star interiors, where strange matter may be present{\cite{Chatterjee2016}}. A precise comparison of the masses of the hypertriton and the antihypertriton allows us to test CPT symmetry in a nucleus with strangeness for the first time, and we observe no deviation from the expected exact symmetry
