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)
Dartmouth researchers find the root of the evolutionary emergence of vertebrates
Dartmouth College researchers and colleagues from the University of Bristol in the U.K. have traced the beginnings of complex life, i.e. vertebrates, to microRNA. The researchers argue that the evolution of microRNAs, which regulate gene expression, are behind the origin of early vertebrates. view more (2008-02-12)
Bits of 'junk' RNA aid master tumor-suppressor gene
Little-known bits of RNA help master tumor-suppressor gene do its job, U-M cancer researchers find. Three micro RNA genes appear to be key partners of protective gene p53; their loss is linked to common type of lung cancer. view more (2007-08-24)
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)
Chicken genome will help our understanding of humans and improve agriculture
The first full DNA sequence of the chicken (Gallus gallus) genome is published today in the journal Nature. UK scientists have worked closely with 170 researchers from 49 institutes worldwide, to interpret the genome of the chicken. They believe it will help us to understand more about the biology of chickens and will also give us further insights... view more... (2004-12-07)
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...

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)
Mothers transmit DNA through daughters only
Scientists have argued whether or not the often-studied mitochondrial DNA molecule is clonally inherited. It is with assuming clonal inheritance this type of DNA has been used to track the origin of modern human as well as to draw pictures of genetic relationships among other animals and plants. The conflict has now been solved by two evolutionary... view more... (2001-09-06)
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)
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)
Milestone tumor virus publication by Elsevier journal Virology
A recent special edition of the Elsevier journal Virology reviews the past, present, and future of the exciting field of small DNA tumor viruses. view more (2009-04-10)
Researchers gain insight into mechanism underlying Huntington's
Researchers at the University of Kentucky Markey Cancer Center and Graduate Center for Toxicology (GCT) have gained new insight into the genetic mechanisms underlying Huntington's disease and other neurodegenerative or neuromuscular disorders caused by trinucleotide repeats (or TNRs) in DNA. view more (2009-07-14)
When Good DNA Goes Bad: Backward DNA leads to DNA breaks associated with leukemia, study finds
When otherwise normal DNA adopts an unusual shape called Z-DNA, it can lead to the kind of genetic instability associated with cancers such as leukemia and lymphoma. view more (2006-02-13)
Gene for neat repair of DNA discovered
Researchers from the Erasmus University in Rotterdam have demonstrated that a gene helps in the neat repair of DNA. Without this gene the body would repair damaged DNA in a careless manner more often. This causes new damage, which can lead to cancer. The careless repair of damaged DNA can cause mutations and can result in cancer. Cell biologists... view more... (2002-01-24)
JILA finds flaw in model describing DNA elasticity
DNA, the biomolecule that provides the blueprint for life, has a lesser-known identity as a stretchy polymer. view more (2007-09-17)
NYU chemists create 'nanorobotic' arm to operate within DNA sequence
New York University chemistry professor Nadrian C. Seeman and his graduate student Baoquan Ding have developed a DNA cassette through which a nanomechanical device can be inserted and function within a DNA array, allowing for the motion of a nanorobotic arm. view more (2006-12-08)
