Caenorhabditis elegans is a free-living, transparent nematode (roundworm), about 1 mm in length, which lives in temperate soil environments.
A team of researchers led by Yale-NUS College has found evidence that metabolic dysfunction is a primary cause of Alzheimer's disease.
The brain's neural activity-;long implicated in disorders ranging from dementia to epilepsy-;also plays a role in human aging and life span, according to research led by scientists in the Blavatnik Institute at Harvard Medical School.
Most people have some idea of how important iron is to their health, but Iqbal Hamza, professor in Animal and Avian Sciences, has made his seventeen-year career at the University of Maryland all about the study of iron and heme trafficking and regulation in the body.
Every day, people are exposed to myriad chemicals, both natural and synthetic. Some of these compounds may affect human physical development, but testing them directly on people would be grossly unethical.
Researchers at the Max Delbrueck Center for Molecular Medicine have identified an epigenetic mechanism that appears to strongly influence healthy aging.
EU-funded researchers have discovered an important new mechanism by which cells flag and repair damage to their DNA - an unexpected finding that could improve the treatment of diseases such as cancer.
Aging research indicates that better healthspan--the quality of life as we age--may be more important than lifespan.
Over one billion people, including 880 million children, are infected with intestinal nematode worms, such as roundworms, hookworms and tapeworms, according to the World Health Organization.
Muscle decline caused by aging and certain diseases could be dramatically slowed by stopping a chain reaction that damages cells, new research shows.
Princeton University researchers have discovered that learned behaviors can be inherited for multiple generations in C. elegans, transmitted from parent to progeny via eggs and sperm cells.
A new Cornell University-led study finds that the genome for a widely researched worm, on which countless studies are based, was flawed. Now, a fresh genome sequence will set the record straight and improve the accuracy of future research.
Dopamine is responsible for sex-specific variations in common behaviors, finds a study of worm movements published in JNeurosci.
As an organism grows and responds to its environment, genes in its cells are constantly turning on and off, with different patterns of gene expression in different cells. But can changes in gene expression be passed on from parents to their children and subsequent generations?
A group of Brazilian scientists have long conducted experiments with roundworms to investigate the role of schizophrenia-linked genes in patients' response to antipsychotic drugs. The results obtained thus far point to new ways of understanding resistance to certain classes of medication.
Using roundworms, one of Earth's simplest animals, Rice University bioscientists have found the first direct link between a diet with too little vitamin B12 and an increased risk of infection by two potentially deadly pathogens.
It's the small pieces that make the big picture, and in this case, the pieces can't be seen by the naked eye. New research at the Okinawa Institute of Science and Technology Graduate Universit used microscopy techniques to piece together the brain of the millimeter-long Caenorhabditis elegans, revealing that their neurons fire action potentials - a spike in voltage due to neurons sending sensory information in the cell membrane.
Genetic manipulation that more than doubles lifespan also leads to better offspring - according to new collaborative research from the University of East Anglia and Uppsala University.
Having absolute control of the activity of a molecule in an organism. Deciding when, where and how a drug is activated. These are some of the goals expected to be reached with the so-called photoswitchable molecules, compounds that, in the presence of certain light waves, change their properties.
Perpetually hungry, worms are strategic when it comes to searching for food. The microscopic roundworm Caenorhabditis elegans, or C. elegans, is known to spend up to 20 minutes seeking out snacks in its immediate surroundings before endeavoring to look elsewhere.
The smell of food induces a variety of physiological processes in our body. Thus, the production of saliva and digestive enzymes is stimulated before the actual food intake in order to prepare the gastrointestinal tract for the upcoming digestive process.
