Caenorhabditis elegans is a free-living, transparent nematode (roundworm), about 1 mm in length, which lives in temperate soil environments.
The bacterium Vibrio cholerae was discovered more than 150 years ago but remains as one of the main causes of bacterial infectious disease globally, especially in low-income nations where it occurs endemic, and outbreaks of cholera disease can lead to major epidemics.
Researchers have identified a new inherited neurodevelopmental disease that causes slow growth, seizures and learning difficulties in humans.
Ask a dozen people about their greatest fears, and you'll likely get a dozen different responses. That, along with the complexity of the human brain, makes fear--and its close cousin, anxiety--difficult to study.
Women have been told for years that if they don't have children before their mid-30s, they may not be able to. But a new study from Princeton University's Coleen Murphy has identified a drug that extends egg viability in worms, even when taken midway through the fertile window, which could theoretically extend women's fertility by three to six years.
A new research study reveals RAC1 protein could be a new therapeutic target to study the molecular mechanisms related to the neurodegenerative processes in Parkinson's disease.
Researchers at the University of Michigan Life Sciences Institute found that a previously dismissed genetic mechanism may contribute to nicotine dependence, and to the withdrawal effects that can make quitting smoking so difficult.
Monash University scientists are one step closer to solving the riddle of how nerves can self-heal. The scientists from the Biomedicine Discovery Institute (BDI) have found signals in the tiny transparent roundworm that control the mechanism by which severed nerves self-heal.
Environmental health scientist Alicia Timme-Laragy at the University of Massachusetts Amherst recently received a $1.9 million grant from the National Institute of Environmental Health Sciences to study the health effects of two environmental pollutants, perfluoro-octanesulfonic acid (PFOS) and its recent replacement chemical, perfluoro-butanesulfonic (PFBS).
Investigators at Case Western Reserve University School of Medicine and University Hospitals Health System have identified a new molecular pathway that controls lifespan and healthspan in worms and mammals.
Two recent Northwestern University studies shed new light on the mystery of the leading cause of birth defects and miscarriage, laying the foundation for further research in an understudied but crucially important field of genetic study.
The heredity substance DNA is the blueprint of our life. Like an instruction manual it contains all the information needed for cells and the body to function properly.
Regular exercise is considered an important form of treatment for heart failure, a condition in which the heart is unable to pump enough blood to meet the body's needs.
Scientists reveal that a fault in the process that copies DNA during cell division can cause epigenetic changes that may be inherited for up-to five generations.
Restricting how much you eat without starving has been shown to robustly extend lifespan in more than 20 species of animals including primates.
Many complicated neurological disorders appear to have a gender bias. Women, for example, are more likely to develop Alzheimer's disease, while men are at greater risk for Parkinson's disease.
Microscopic probes developed at Rice University have simplified the process of measuring electrical activity in individual cells of small living animals. The technique allows a single animal like a worm to be tested again and again and could revolutionize data-gathering for disease characterization and drug interactions.
The University of Liverpool has received a £390,000 grant from Medical Research Council to conduct research into how mutations in genes can cause epilepsy.
Programmed cell death is an integral part of embryonic development. Exploring the regulation of the process, Ludwig-Maximilians-Universitaet in Munich researchers have shown that so-called microRNAs protect the precursors of neurons from 'precocious' elimination.
The discovery of a novel protein that links aging and age-dependent retinal diseases could lead to potential new treatments for conditions that cause sight loss in later life.
University of Georgia researchers have found a way to enhance chemotherapy's cancer-killing powers, bringing science one step closer to a more complete cancer treatment.
