Beneficial Mutations have still not been found in the wild, though their existence was confidently predicted in the 1940s. Article published at http://www.takeondarwin.com asks, could they, like Unicorns, actually be mythical? ROSENDALE NY (PRWEB) February 06, 2013 Existence of the Beneficial Mutation was confidently predicted in the 1940s as part of the Modern Synthesis. In fact, if the Beneficial Mutation could be shown not to exist, the Modern Synthesis itself might be brought into...

Mutations which affect the gene ASXL3 cause a novel syndrome similar to Bohring-Opitz syndrome, finds a study published in BioMed Central's open access journal Genome Medicine. This molecular definition distinguishes these children from those with Bohring-Opitz, and other similar syndromes, and highlights a technique able to help define rare diseases. When Dr Ropers from the Max-Planck Institute for Molecular Genetics in Berlin found a child with non-specific symptoms, including small size...

Surprising result suggests that enhancing these mutations´ impact could offer a new way to treat cancer. A typical cancer cell has thousands of mutations scattered throughout its genome and hundreds of mutated genes. However, only a handful of those genes, known as drivers, are responsible for cancerous traits such as uncontrolled growth. Cancer biologists have largely ignored the other mutations, believing they had little or no impact on cancer progression. But a new study from...

Mutant Gene Responsible For Pigeons' Funky Hair-Dos

Brett Smith for redOrbit.com - Your Universe Online According to a new study in the journal Science Express, an international team of researchers has sequenced the entire rock pigeon genome, and made some interesting discoveries in the process. "Birds are a huge part of life on Earth, but we know surprisingly little about their genetics," study co-author Michael Shapiro, a biologist at the University of Utah, said in a statement. Using cutting edge sequencing techniques, the...

Breast Cancer Mutation Linked To Early Onset Menopause
2013-01-30 09:42:51

Connie K. Ho for redOrbit.com — Your Universe Online Scientists from the University of California, San Francisco (UCSF) recently conducted a study that showed a significantly earlier onset of menopause for women who inherited a mutation in one of the breast cancer susceptibility (BRCA) genes. These genes, known as BRCA1 or BRCA2, are tumor suppressor genes, meaning that they prevent uncontrolled cell growth. The study is of particular importance as it points to the possibility...

Johns Hopkins study links 1 family's rare gene mutation to brain cell abnormality and mental illness Johns Hopkins researchers have identified a rare gene mutation in a single family with a high rate of schizophrenia, adding to evidence that abnormal genes play a role in the development of the disease. The researchers, in a report published in the journal Molecular Psychiatry, say that family members with the mutation in the gene Neuronal PAS domain protein 3 (NPAS3) appear at high risk...

When Charles Darwin first sketched how species evolved by natural selection, he drew what looked like a tree. The diagram started at a central point with a common ancestor, then the lines spread apart as organisms evolved and separated into distinct species. In the 175 years since, scientists have come to agree that Darwin´s original drawing is a bit simplistic, given that multiple species mix and interbreed in ways he didn´t consider possible (though you can´t fault the guy...

Slime Mold Gets Upper Hand By Cheating
2013-01-09 13:38:37

BioMed Central A 'cheater' mutation (chtB) in Dictyostelium discoideum, a free living slime mold able to co-operate as social organism when food is scarce, allows the cheater strain to exploit its social partner, finds a new study published in BioMed Central's open access journal BMC Evolutionary Biology. The mutation ensures that when mixed with 'normal' Dictyostelium more than the fair share of cheaters become spores, dispersing to a new environment, and avoiding dying as stalk cells....

Autism And Other Disorders May Be Caused By Genetic Hotspot Mutations
2012-12-21 06:47:01

[ Watch the Video: Mutation Hotspots in Autism Genes ] Connie K. Ho for redOrbit.com — Your Universe Online A group of international researchers led by a team of investigators from the School of Medicine at the University of California, San Diego (UCSD), recently revealed a new study that provides signals as to the causes of autism and other related disorders. With the findings, it is possible that there are elevated mutation rates in specific parts of the genome that adds to...


Word of the Day
omadhaun
  • A fool; a simpleton: a term of abuse common in Ireland and to a less extent in the Gaelic-speaking parts of Scotland.
This word is partly Irish in origin.
