Wellcome Trust Sanger Institute Cell's unique mutations used to trace history back to its origins in the embryo Researchers have developed new methods to trace the life history of individual cells back to their origins in the fertilized egg. By looking at the copy of the human genome present in healthy cells, they were able to build a picture of each cell's development from the early embryo on its journey to become part of an adult organ. During the life of an individual, all cells...

Scientists turn stem cells into a fish embryo, overcoming major biological challenge. Charlottesville, VA (PRWEB) April 04, 2014 Scientists at the University of Virginia School of Medicine have overcome one of the greatest challenges in biology and taken a major step toward being able to grow whole organs and tissues from stem cells. By manipulating the appropriate signaling, the UVA researchers have turned embryonic stem cells into a fish embryo, essentially controlling embryonic...

Some people possess a small number of cells in their bodies that are not genetically their own; this condition is known as microchimerism. It is difficult to determine potential health effects from this condition because of humans’ relatively long life-spans. Now, researchers at the University of Missouri have found that microchimerism can be found in dogs as well. Jeffrey Bryan, an associate professor of oncology at the MU College of Veterinary Medicine and director of...

First Time Evidence: Leftover Male Fetal DNA Found In Female Brains
2012-09-27 09:59:56

Lawrence LeBlond for redOrbit.com - Your Universe Online A small amount of male DNA can be found in the brains of women, something researchers at Fred Hutchinson Cancer Research Center (FHCRC) believe may be the result of leftover DNA in the mother´s body by a male fetus, which occurs relatively frequently. In a first-of-its-kind study, William Chan, PhD, Department of Biochemistry at University of Alberta, and J. Lee Nelson, senior author at FHCRC, looked at microchimerism--the...

Researchers at Duke University Medical Center may finally have discovered why people with sickle cell disease get milder cases of malaria than individuals who have normal red blood cells. In a finding that has eluded scientists for years, Duke researchers discovered that genetic material in red blood cells may help alter parasite activity via a novel mechanism that alters parasite gene regulation. "One of the most interesting findings in our study is that the human microRNA (very small...

From Embryonic Stem Cells, A Sperm Replacement And Easier Path To Genetic Modification
2012-04-26 10:39:13

Researchers reporting in the April 27 issue of the journal Cell , a Cell Press publication, have devised a new and improved method for producing genetically modified animals for use in scientific research. The method relies on haploid embryonic stem cells (haESCs) instead of sperm to artificially fertilize immature egg cells. Such stem cells are similar to sperm in that they carry only genetic material from a mouse "dad." Not only will the advance make it easier to produce genetically...

Scientists now able to view critical aspects of mammalian embryonic development using new technique A novel approach in the study of the development of mammalian embryos was today (14 February) reported in the journal Nature Communications. The research, from the laboratory of Professor Magdalena Zernicka-Goetz of the University of Cambridge, enables scientists to view critical aspects of embryonic development which was previously unobservable. For several decades it has been possible...

Knockout Mouse
2013-10-02 11:52:01

A Knockout Mouse is a genetically engineered mouse in which researchers have inactivated, or “knocked out,” an existing gene by replacing it or disrupting it with an artificial piece of DNA. The loss of gene activity frequently causes changes in a mouse’s phenotype, which includes appearance, behavior, or other apparent and biochemical characteristics. Knockout mice are significant animal models for studying the role of genes which have been sequenced but whose functions haven’t...

Pegasus (the winged horse) Constellation -- Location: Visible in both Hemispheres Coordinates: Right Ascension: 22h; Declination: +20; Source: Greek mythology Pegasus, the winged horse, was the son of Poseidon and Medusa. Medusa had been one of three beautiful sisters. Athena was angered that Medusa met with Poseidon in one of her temples. She changed Medusa into a terrible monster. Zeus kept Pegasus out of the world to placate Athena. Pegasus (and the warrior Chrysaor) sprang from...

callithump
  • A somewhat riotous parade, accompanied with the blowing of tin horns, and other discordant noises; also, a burlesque serenade; a charivari.
'Callithump' is a back-formation of 'callithumpian,' a 'fanciful formation' according to the Oxford English Dictionary. However, the English Dialect Dictionary, says 'Gallithumpians' is a Dorset and Devon word from the 1790s that refers to 'a society of radical social reformers' or 'noisy disturbers of elections and meetings.'
