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)
Chemotherapy resistance: Checkpoint protein provides armor against cancer drugs
Cell cycle checkpoints act like molecular tripwires for damaged cells, forcing them to pause and take stock. view more (2009-08-28)
Tanning Devices - Fast Track to Skin Cancer?
An all over tan is fashionable and large numbers of people, especially young women, achieve this by using sunbeds. Professor Antony Young, of King's College London, has reviewed the evidence that links sunbed use to malignant melanoma; a skin cancer that is fatal if not detected and treated early. Malignant melanoma is a cancer of the skin's cells... view more... (2004-01-15)
Couples with fertility problems where the man is over 35 have increased difficulty in conceiving
Pregnancy rates decrease and miscarriages increase when a father is over 35 years of age, a scientist will tell the 24th annual conference of the European Society of Human Reproduction and Embryology. view more (2008-07-07)
Delft University of Technology research might prevent asphalt damage
Repairing asphalt damage caused by water infiltration costs a great deal of money and produces extra traffic delays. view more (2007-06-06)
Novel regulatory mechanism identified for key tumor suppressor p53
Collaborating scientists from The Wistar Institute in Philadelphia and The Vienna Biocenter in Austria have identified a novel mechanism involved in normal repression of the p53 protein, perhaps the single most important molecule for the control of cancer in humans. view more (2006-11-16)
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)
Glucosamine supplements reduce knee pain
Glucosamine supplements reduce knee pain in people with cartilage damage and possibly the degenerative joint disease osteoarthritis, concludes research in the British Journal of Sports Medicine. view more (2003-01-24)
Healing heart attack victims, one cell at a time
By using the amount of carbon 14 in the atmosphere from above-ground nuclear testing in the 1950s and 1960, researchers have determined that cells in the human heart develop into adulthood. view more (2009-04-03)
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...

Mapping a clan of mobile selfish genes
Much of human DNA is the genetic equivalent of e-mail spam: short repeated sequences that have no obvious function other than making more of themselves. view more (2008-10-23)
Researchers find the mechanism by which cells resist chemotherapy
In his paper, to be published in The EMBO Jorunal, Dr Surrallés describes how proteins of the Fanconi/BRCA pathway recognise the presence of genetic mutations in order to repair them. view more (2007-03-05)
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)
New long-term data suggests Abatacept treatment
New data from the long-term extension of the AIM (Abatacept in Inadequate responders to Methotrexte) trial, announced today at the Annual European Congress of Rheumatology, suggests the selective T-cell co-stimulation modulator abatacept sustains inhibition of radiographic progression over 2 years in rheumatoid arthritis patients with an... view more...

New look at DNA hints at origin of ultraviolet damage
Chemists at Ohio State University have gained new insight into how sunlight affects DNA. And what they found overturns ideas about genetic mutation that originated decades ago. view more (2005-08-25)
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)
Gene activity reveals dynamic stroma microenvironment in prostate cancer
As stroma - the supportive framework of the prostate gland - react to prostate cancer, changes in the expression of genes occur that induce the formation of new structures such as blood vessels, nerves and parts of nerves. view more (2009-06-09)
New role for gene that counteracts formation of tumors
The researchers, connected to Ghent University, have discovered the function of an important mediator involved in suppressing the development of tumors. view more (2005-08-26)
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)
