Leveraging national data from the Society for Assisted Reproductive Technology (SART), the Brigham researchers found that, in cycles using freshly retrieved donor eggs, fresh embryo transfers were indeed associated with significantly higher live birth rates compared to frozen embryo transfers. The team's findings are published in JAMA.
As climate change causes the world's oceans to warm, baby sharks are born smaller, exhausted, undernourished and into environments that are already difficult for them to survive in.
Variations and changes in national and state rates of neonatal abstinence syndrome and maternal opioid-related diagnoses were examined in this observational study.
Research on cycad trees in Colombia, Guam, and the Philippines has illuminated how knowledge of their branching behavior may benefit conservation decisions for the endangered plants. In a study published in the December issue of the journal Horticulturae, scientists from the University of Guam and the Montgomery Botanical Center in Florida show that the number of times a cycad tree produces a branch can be used to infer the sex of the tree.
Scientists from the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA have developed a technique that will enable researchers to more efficiently isolate and identify rare T cells that are capable of targeting viruses, cancer and other diseases.
Oahu's ecosystems have been so affected by species extinctions and invasions that most of the seeds dispersed on the island belong to nonnative plants, and most of them are dispersed by nonnative birds.
Research suggests that MLL4 controls the production of neurons that secrete growth hormone-releasing hormone (GHRH) in a part of the brain called the hypothalamus.
Epigenetic biomarkers in human sperm have been identified that can indicate a propensity to father children with autism spectrum disorder. In the study, researchers identified a set of genomic features, called DNA methylation regions, in sperm samples from men who were known to have autistic children. Then in a set of blind tests, they were able to use the presence of these features to determine whether other men had fathered autistic children with 90% accuracy.
Researchers have brought together expertise in bioinformatics, cytogenetics, developmental and molecular biology to produce and analyse the first ever echidna genome and a greatly improved, high quality platypus genome sequence.
Second only to the spiny lobster, the queen conch is a prized delicacy long harvested for food and is revered for its beautiful shell. Conch populations have dwindled so low, creating a dire and urgent situation in ecological and economic terms. To preserve this significant molluscan fishery in the Caribbean, the world's leading expert on queen conch aquaculture has published an 80-page, step-by-step user manual that provides complete illustrations and photos of how to culture and restore the queen conch.
