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.
The approach could increase scientists understanding of how these critical immune cells respond to a wide range of illnesses and advance the development of T cell therapies. This includes immunotherapies that aim to boost the function and quantity of cancer or virus-targeting T cells and therapies intended to regulate the activity of T cells that are overactive in autoimmune diseases such as diabetes and multiple sclerosis.
E-Mail Nausea and vomiting symptoms during pregnancy start within a three day timeframe for most women, according to new study from University of Warwick More accurate measurement achieved by calculating start of pregnancy from date of ovulation - rather than last menstrual period Points to a potential biological cause for nausea and vomiting, and supports the view that the condition has been trivialised
Researchers from the University of Warwick have narrowed the time frame that nausea and vomiting during pregnancy will potentially start to just three days for most women, opening up the possibility for scientists to identify a biological cause for the condition.

BOSTON For women hoping to achieve a pregnancy using freshly retrieved donor eggs, a new retrospective study led by researchers from Brigham and Women s Hospital may provide important insight. Brigham senior author Janis H. Fox, MD, had observed that when freshly retrieved donor eggs were used, pregnancy rates were higher for fresh compared to frozen embryo transfers. Fox and her colleagues were intrigued by this observation. The team set out to scientifically determine if this observation would be replicated in a larger sample of recipients. 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

New research has found 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.
Lead author of the study Carolyn Wheeler is a PhD candidate at the ARC Centre of Excellence for Coral Reef Studies at James Cook University (Coral CoE at JCU) and the University of Massachusetts. She examined the effects of increased temperatures on the growth, development and physiological performance of epaulette sharks an egg-laying species found only on the Great Barrier Reef. She and her team studied the sharks as embryos and as hatchlings.
