Community Caretaking Exception Saves Lives . . . The Supreme Court Disagrees, Gabriella Lorenzo

Touro Law Review

As many are aware, the Fourth Amendment protects the people against unreasonable searches and seizures. A warrant is necessary for said activities. While there are a few exceptions to the warrant requirement, the Supreme Court recently held that the community caretaking exception does not extend to the home. Extending this exception to the home would allow police officers to enter and engage in functions that are unrelated to the investigation of a crime. Essentially, this exception would allow police to aid individuals and prevent serious, dangerous situations to protect the community. This Note discusses why the Supreme Court erred in …

Medical Taking Of Human Biological Material V. Traditional “Art Looting”: Henrietta Lacks And The Complex Ethical And Legal Liability Questions Raised By Her Unfortunate Case, Alyaa Chace

Touro Law Review

During a poignant saga of American history, Henrietta Lacks stands as an emblem of both scientific triumph and ethical controversy. In 1951, Mrs. Lacks, a tobacco farmer and mother of five, visited Johns Hopkins Hospital for treatment of what was later discovered to be advanced stage cervical cancer. Her doctors treated her with radium, which was standard practice at the time. However, Mrs. Lacks’s cancer rapidly metastasized and she ultimately passed away just months later on October 4, 1951, at the age of 31. During the course of her treatment, Mrs. Lacks’s cells were non-consensually removed for purposes of scientific …

Embedded State Estimation For Optimization Of Cislunar Space Domain Awareness Constellation Design, Thomas Henry Clareson

Diet And Population Genomics Of River Otters (Lontra Canadensis) In West Virginia, Eden Grace Nitza

Graduate Theses, Dissertations, and Problem Reports (ETD)

North American river otters (Lontra canadensis), hereafter, otters, are apex predators in aquatic ecosystems across Appalachia, and thus have important impacts on their ecosystems such as food web regulation, nutrient cycling, and reducing the impacts of invasive species. Otters were extirpated from most of Appalachia, including all of West Virginia, by the mid-1900’s due to habitat destruction and overharvest. The West Virginia Division of Natural Resources (WVDNR) began an otter reintroduction program in 1984 which translocated approximately 250 otters into the state by 1997. This reintroduction program was largely considered successful, and a regulated harvest season was opened …

The Effects Of Daily Magnesium Citrate Supplementationon Grip Strength, Carolina Cano, Holly King

Loma Linda University Research Reports

Magnesium (Mg) is thought to play an essential role in physical strength because it catalyzes more than 300 enzymatic reactions involved in energy metabolism and cell growth. Magnesium also aids in the hydrolysis of ATP in glycolysis, acting as a coenzyme in three critical reactions and in crossbridge formation in the muscle contraction cycle. Despite these roles, approximately 60% of the US adult population does not meet the RDA for Mg. Previous studies found inconsistent results on the effects of Mg on physical performance. However, most studies agreed on magnesium's potential as an ergogenic aid.
