In a new study published in JAMA Pediatrics, researchers at Children's Hospital Colorado (Children's Colorado) have found that tetrahydrocannabinol (THC), the psychoactive component of marijuana, stays in breast milk for up to six weeks, further supporting the recommendations of the American Academy of Pediatrics, the American College of Obstetricians and Gynecologists and the Academy of Breastfeeding Medicine to abstain from marijuana use during pregnancy and while a mother is breastfeeding.
Children's National Hospital researchers explored how preterm birth disrupts Purkinje cell function, resulting in locomotor learning deficits. The study brought together a cross-disciplinary team of neuroscientists and neonatologists to devise a unique and novel method of analyzing neural circuitry of mice while they underwent movement exercises.
Scientists reporting in the journal Current Biology on March 8 have discovered two species of sacoglossan sea slug that can do even better, shedding and then regenerating a whole new body complete with the heart and other internal organs. The researchers also suggest that the slugs may use the photosynthetic ability of chloroplasts they incorporate from the algae in their diet to survive long enough for regeneration.
The process of egg formation in fruit flies relies on physical phenomena analogous to the exchange of gases between balloons of different sizes, according to a study by MIT biologists and mathematicians.
New research published in two papers by UC San Diego scientists describes novel achievements designed to make the implementation of gene drives safer and more controllable. The new split drive and home-and-rescue systems address concerns about the release of gene drives in wild populations.
Shark scientists at Georgia Aquarium, Scripps Institution of Oceanography at UC San Diego, and Dalhousie University are challenging the status quo in shark and ray mating research in a new study that looks at biological drivers of multiple paternity in these animals.
In a new paper published by Nature Communications, The Lundquist Institute (TLI) Investigator Wei Yan, MD, PhD, and his research colleagues spell out an innovative strategy that has led to the discovery of a natural compound as a safe, effective and reversible male contraceptive agent in pre-clinical animal models. Despite tremendous efforts over the past decades, the progress in developing non-hormonal male contraceptives has been very limited.
The goal of the research, Luo said, is to better understand the benefits of microbes in order to recommend solutions, such as probiotics, that could strengthen the neonatal immune system. These efforts could lead to new strategies in medicine -- and healthier babies.
While consumers look out for the Dolphin Safe mark on seafood purchases, a major research stocktake of Australian-New Zealand waters gives new guidelines to managers of dolphin fisheries. The extensive new genomic study of almost 500 common dolphins (Delphinus delphis), spanning multiple spatial areas of more than 1500 sq km from the southern and east coast of Australia to Tasmania and New Zealand, calls for greater collaboration between the two countries' conservation and fisheries plans.
The first proof of the origin of malignant rhabdoid tumour (MRT), a rare childhood cancer, has been discovered by researchers at the Wellcome Sanger Institute, the Princess Máxima Center for Pediatric Oncology in the Netherlands, and their collaborators.
