RSRF-Funded Research Links Rett Syndrome to Mitochondrial Gene
New research from the lab of Adrian Bird, a molecular geneticist at the University of Edinburgh, Scotland, reveals that abnormally high levels of a protein called Uqcrc1 in the brains of mouse models of Rett Syndrome cause mitochondria—-the cells' powerhouses—to work overtime. view more (2006-06-26)
Sea snails break the law
Lizards gave rise to legless snakes. Cave fishes don't have eyeballs. In evolution, complicated structures often get lost. Dollo's Law states that complicated structures can't be re-evolved because the genes that code for them were lost or have mutated. view more (2007-04-25)
Genetic study of Neanderthal DNA reveals early split between humans and Neanderthals
In the most thorough study to date of the Neanderthal genome, scientists suggest an early human-Neanderthal split. The two species have a common ancestry, say the authors, but do not share much else after evolving their separate ways. view more (2006-11-16)
Evolutionary scrap-heap challenge: Antifreeze fish make sense out of junk DNA
Scientists at the University of Illinois have discovered an antifreeze-protein gene in cod that has evolved from non-coding or 'junk' DNA. view more (2006-04-04)
Nixing immaturity in red blood cells
A process of self-digestion called autophagy prompts the maturation of red blood cells. Without a protein called Nix, the cells would not effectively rid themselves of organelles called mitochondria and consequently become short-lived, leading to anemia, said researchers at Baylor College of Medicine in Houston in a report that appears online... view more...

Handheld DNA detector
A researcher at the National University at San Diego has taken a mathematical approach to a biological problem - how to design a portable DNA detector. view more (2008-03-11)
Finding that 1-in-a-billion that could lead to disease
Errors in the genetic code can give rise to cancer and a host of other diseases, but finding these errors can be more difficult than looking for the proverbial needle in the haystack. view more (2007-08-20)
Y chromosome study sheds light on Athapaskan migration to southwest US
A large-scale genetic study of native North Americans offers new insights into the migration of a small group of Athapaskan natives from their subarctic home in northwest North America to the southwestern United States. The migration, which left no known archaeological trace, is believed to have occurred about 500 years ago. view more (2008-07-16)
DNA repair mechanisms relocate in response to stress
Like doctors making house calls, some DNA repair enzymes can relocate to the part of the cell that needs their help, a collaborative team of scientists at Emory University School of Medicine has found. view more (2009-03-27)
Cash boost for research into leukaemia
Scientists from the University of Sussex in Brighton have been awarded £147,000 by the Leukaemia Research Fund (LRF) to look at abnormalities in DNA damage and repair that occur in some leukaemias and lymphomas. The research team ¾ led by Dr Penny Jeggo at the Genome Damage and Stability Centre ¾ will look at Seckel Syndrome, a rare... view more... (2002-09-11)
DNA-Proofed Documents To Arrive 'By 2006'
The commercial launch of the first ever fool-proof document security system is planned for 2006, reports Marina Murphy in Chemistry & Industry magazine. The system, which uses DNA fingerprinting, will allow documents to be authenticated with an accuracy of billions to one against duplication, according to the Australian scientists working on... view more...

Researchers identify protein pathway involved in Parkinson disease development
Scientists have found a novel signaling pathway in cells that is altered by genetic mutations recently identified in Parkinson disease development. view more (2007-06-19)
ISU researcher identifies key function in protein, cell transcription
When cells decide to make proteins, key building blocks of all organisms, they need to know where to start reading the instructions for assembling them. view more (2009-05-04)
Professor sheds light on DNA mechanisms
By manipulating individual atoms in DNA and forming unique molecules, a Georgia State University researcher hopes to open new avenues in research towards better understanding the mechanisms of DNA replication and transcription, and perhaps leading to new treatments for diseases. view more (2009-07-20)
Dawn of human matrilineal diversity
A team of Genographic researchers and their collaborators have published the most extensive survey to date of African mitochondrial DNA (mtDNA). view more (2008-04-25)
Faster, more cost-effective DNA test for crime scenes, disease diagnosis
Scientists in Japan are reporting development of a faster, less expensive version of the fabled polymerase chain reaction (PCR) a DNA test widely used in criminal investigations, disease diagnosis, biological research and other applications. view more (2009-07-09)
New research promises cure by mouth
A researcher at Aston University in Birmingham has become the first in the UK to investigate a new type of vaccination delivery that could revolutionise how we are protected against diseases including flu, hepatitis and, most excitingly, cancer. Dr Yvonne Perrie from the School of Life & Health Sciences has received a research grant from The... view more... (2002-12-02)
University of Minnesota researchers take new look at cellular suicide
Like a bodyguard turned traitor, a protein whose regular job is to help repair severed DNA molecules will, in some cases, join forces with another protein to do the opposite and chop the DNA to bits. view more (2006-07-07)
Protein helps cells duplicate correctly, avoid becoming cancer
A Purdue University researcher has discovered that the absence of certain proteins needed for proper cell duplication can lead to cancer. view more (2009-10-06)
Selfing DNA prevents genomes from mixing
Genomes of multicellular organisms are one of the greatest mysteries of biology. The more is discovered about them, the more questions are to be answered. One of such questions is connected with the size of a genome. As is known since the middle of the 20th century, the level of organization of an organism does not depend on the genome size, i.e.,... view more... (2002-10-11)
