Scientists from Newcastle University, UK led by Professor Patrick Chinnery, have created an embryo with three separate parents. The team believe the technique could help to eradicate a whole class of hereditary diseases, including some forms of epilepsy and ensure women with genetic defects do not pass the diseases on to their children.
Ten severely deformed embryos, left […]
Nature constantly ”shuffles” our genes around in our genome, creating a genetic cocktail of human chromosomes and trying out different changes as it does so. Some of these changes represent neither a positive nor a negative mutation or a competitive advantage. One such ’shuffle’ is eye color.
Originally we all had brown eyes. Then about 6-10,000 years […]
Human chromosomes (grey) capped by telomeres (white)
We all know the benefits of regular exercise but scientists now have proof that it can really make you look younger! Telomeres, regions of highly repetitive DNA at the end of a linear chromosome shorten over time. The shortening of telomeres is strongly correlated with ageing and it is […]
Scientists from deCODE genetics have reported the discovery of two common, single-letter variants in the sequence of the human genome (SNPs) that regulate one of the principle motors of evolution. Versions of the two SNPs, located on chromosome 4p16, have a genome-wide impact on the rate of recombination - the reshuffling of the genome that […]
Most gems, such as diamonds, rubies and sapphires, are crystalline inorganic and inert materials. Within each crystal structure, the atoms have precise locations, which give each material its unique properties. Diamond’s renowned hardness and refractive properties are due to its structure — the precise location of its carbon atoms.
Using just one kind of nanoparticle (gold), North […]
New research has shown evidence that genes have the ability to recognize similarities in each other from a distance, without any proteins or other biological molecules aiding the process. This discovery could explain how similar genes find each other and group together in order to perform key processes involved in the evolution of species.
According to […]
Micrograph images of synthetic Mycoplasma genitalium
J Craig Venter and his team at the J Craig Venter Institute Rockville, Md. Venter continue to expand our horizons of what constitutes life. They have built, from scratch, a synthetic chromosome containing all the genetic material needed to produce a primitive bacterium - this is considered a giant step toward the creation […]
Depression affects enormous numbers of people from across the world. One in four of us will suffer from it at some point in our lives; one in ten will in the next year, and about one in twenty of us is living with the condition right now.
A new book, recently published, suggests depression may have persisted […]
The EU funded GEN2PHEN project plans to internationally orchestrate the electronic gathering and use of data that show how gene sequences (’genotypes’) contribute to individual differences in disease, drug response, and other characteristics (’phenotypes’). These relationships (usually in the form of “genotype-phenotype” information stored in scattered databases) are deemed to become essential for future prognosis, […]
Fellow science blogger Pharyngula has blogged this but I just have to show Genetics and Health readers this wonderful video showing dolphins’ version of home entertainment!
