New test for mysterious metabolic diseases developed at Stanford/Packard
Scientists at Stanford University School of Medicine have devised a much-needed way to monitor and find treatments for a mysterious and devastating group of metabolic diseases that arise from mutations in cells' fuel-burning mechanism. view more (2009-02-11)
Research points to a new way to protect kidneys threatened by insufficient blood or toxins
Better treatments for acute renal failure may be possible by blocking the mitochondrial fragmentation that occurs when kidneys don't get enough blood or are exposed to toxins. view more (2009-05-19)
The flying lemur a close relative
Our pedigree has been revised. Our closest relatives--gorillas, orangutans, chimpanzees, gibbon apes, and baboons--have been joined by an animal whose appearance hardly resembles that of humans: the Dermoptera or the flying lemur. Flying lemurs live in Southeast Asia. The largest species can be 75 cm tall. This animal can glide between trees... view more... (2002-06-19)
Role for CISD2 gene in human disease and lifespan control
In the May 15th issue of G&D, Dr. Ting-Fen Tsai (The National Yang-Ming University, Taiwan) and colleagues present a new animal model of human Wolfram Syndrome, and effectively link CISD2 gene function, mitochondrial integrity and aging in mammals. view more (2009-05-15)
Mitochondria play role in pathogenesis of AD and estrogen-induced neuroprotection
As the major source of free radicals in cells, mitochondria contribute to the high levels of oxidative stress believed to play a role in the pathogenesis of Alzheimer's disease. view more (2008-04-07)
Molecular Biologists Reveal Historical Secrets
By analysing DNA from ancient human remains researchers can determine the sex and ethnicity of our ancestors and help historians to compose a complete picture of their life and customs. In the region of Altai Mountains archaeologists discovered remains of an ancient civilisation. During excavations, they found many bones of newborns and wondered... view more... (2002-07-05)
First research to show that diabetes damages DNA in men's sperm and may affect fertility
Scientists have found that sperm from diabetic men have greater levels of DNA damage than sperm from men who do not have the disease. They warn that such DNA damage might affect a man's fertility. view more (2007-05-03)
Study finds a high caloric diet may prevent the progression of amyotrophic lateral sclerosis
A recent study directed by the Mount Sinai School of Medicine suggests a ketogenic- high caloric diet may prevent the progression of Amyotrophic Lateral Sclerosis (ALS). view more (2006-04-18)
Penn study finds a new role for RNA in human immune response
Researchers at the University of Pennsylvania School of Medicine have published the first study to test the role of RNA chemical modifications on immunity. view more (2005-08-24)
Descartes Research Prize to Professor Jacobs from the University of Tampere
At a ceremony today in Prague Castle, Howy Jacobs, Professor of Molecular Biology in the University of Tampere (Finland), was presented with the EU's Descartes Research Prize 2004, on behalf of his multinational research consortium on 'Mitochondrial Biogenesis, Ageing and Disease' (MBAD). view more (2004-12-02)
Neutral evolution has helped shape our genome
Johns Hopkins researchers have added to the growing mound of evidence that many of the genetic bits and pieces that drive evolutionary changes do not confer any advantages or disadvantages to humans or other animals. view more (2007-07-10)
Coding for arthropods-what's so special about insects and spiders?
The central dogma of molecular biology is that DNA makes RNA makes protein. This relies on a specific underlying code which relates given triplets of RNA nucleotides into specific amino acids. view more (2006-04-25)
Nearly a century later, new findings support Warburg theory of cancer
German scientist Otto H. Warburg's theory on the origin of cancer earned him the Nobel Prize in 1931, but the biochemical basis for his theory remained elusive. view more (2009-01-12)
Nerve cells' power plants caught in a traffic jam
Nerve cells need lots of energy to work properly, and the energy needs to be delivered to the right place at the right time. By inducing a mutation in fruit flies, researchers have figured out that a particular gene governs the movement of cells' energy-producing units, called mitochondria. view more (2005-08-05)
History-hunting geneticists can still follow familiar trail
As the world's first explorers branched away from humanity's birthplace in east Africa some 65,000 years ago, distinct mutations accumulated in the DNA of each population, essentially providing a genetic trail for modern researchers to follow. view more (2006-12-20)
Small molecule offers big hope against cancer
DCA is an odourless, colourless, inexpensive, relatively non-toxic, small molecule. And researchers at the University of Alberta believe it may soon be used as an effective treatment for many forms of cancer. view more (2007-01-17)
Lifestyle can alter gene activity, lead to insulin resistance
A Finnish study of identical twins has found that physical inactivity and acquired obesity can impair expression of the genes which help the cells produce energy. view more (2008-06-19)
Zebrafish to shed light on human mitochondrial diseases
Zebrafish can now be used to study COX deficiencies in humans, a discovery that gives scientists an unprecedented window to view the earliest stages of mitochondrial impairments that lead to potentially fatal metabolic disorders. view more (2007-09-14)
How mitochondria get their membranes bent
Mitochondria are the powerhouses of cells. Underneath their smooth surface they harbor an elaborately folded inner membrane. It holds a multitude of bottleneck like invaginations, which expand into elongated cavities (cristae). view more (2009-06-25)
How a zebra lost its stripes: Rapid evolution of the quagga
DNA from museum samples of extinct animals is providing unexpected information on the extent and effect of the Ice Age as well as the path of species evolution, according to a report by scientists from Yale University, the Smithsonian Institute and the Max Planck Institute for Evolutionary Anthropology. view more (2005-09-27)
