The first baby to be created from an egg that had been matured in the laboratory, frozen, thawed and then fertilized, has been born in Canada. Three other women are pregnant by the same process. The research was presented to the 23rd annual meeting of the European Society of Human Reproduction and Embryology on Monday, July 2.
Evidence gathered from time-lapse recordings of the formation of early embryos (blastocysts) in the laboratory has revealed why embryos created via IVF and undergoing extended culture are more likely to develop into twins than those created via natural conception. Furthermore, the research has shown that the culture in which the IVF embryos are formed is possibly responsible for the embryos dividing into twins.
A team of biomedical engineers at Virginia Tech and the University of California at Berkeley has developed a new minimally invasive method of treating cancer, and they anticipate clinical trials on individuals with prostate cancer will begin soon.
For women at high risk of breast cancer, use of magnetic resonance imaging (MRI) plus X-ray mammography for screening will detect more breast cancers than mammography alone, a new technology assessment has found.
The health care system in California could save nearly $1.3 million a year with few adverse public health effects if it discontinued universal tuberculosis skin testing of children entering kindergarten, according to a new study by researchers at the University of California, San Francisco.
Psychologists from the University of Exeter have identified an “early warning signal” in the brain that helps us avoid repeating previous mistakes. Published in the Journal of Cognitive Neuroscience, their research identifies, for the first time, a mechanism in the brain that reacts in just 0.1 seconds to things that have resulted in us making errors in the past.
A vital molecule for resistance to food allergy has been identified and offers a potential target for therapy. There is currently no way to treat food allergy and the only way for sufferers to manage the problem is to avoid certain foods and make sure they have injectable adrenaline at hand.
New findings on the mechanisms that trigger stress-induced obesity, published today in Nature Medicineonline, could offer hope to millions.
In what they call a “stunning research advance,” investigators at Georgetown University Medical Center have been able to use simple, nontoxic chemical injections to add and remove fat in targeted areas on the bodies of laboratory animals. They say the discovery, published online in Nature Medicine on July 1, could revolutionize human cosmetic and reconstructive plastic surgery and treatment of diseases associated with human obesity.
By using a new kind of genomic technology, a new study unveils a special code — not within DNA, but within the so-called “chromatin” proteins surrounding it — that could unlock the mysterious developmental choices made by mammalian cells, allowing them to assume roles as diverse as liver cells and neurons.
