Caenorhabditis elegans is a free-living, transparent nematode (roundworm), about 1 mm in length, which lives in temperate soil environments.
KAIST researchers have been able to dial up and down creatures' lifespans by altering the activity of proteins found in roundworm cells that tell them to convert sugar into energy when their cellular energy is running low.
Researchers have demonstrated that a fatty acid called dihomogamma-linolenic acid, or DGLA, can kill human cancer cells.
Ordered and variable animal behaviours emerge to explore and adapt to the environment. They are generally considered as the combination of a series of stereotyped motor primitives. However, how the nervous system shapes the dynamics of motor sequences remains to be solved.
A research team led by Dr Chaogu Zheng from the School of Biological Sciences at the University of Hong Kong, in collaboration with a team led by Professor Martin Chalfie (2008 Nobel Laureate in Chemistry) from the Department of Biological Sciences at Columbia University, recently discovered an unexpected role of the heat shock proteins, also known as the molecular chaperones, during neuronal differentiation, which refers to the process a neuron takes to acquire its shape and function.
In the famous words of movie character Forrest Gump, "Life is like a box of chocolates; you never know what you're gonna get."
Exposure to bisphenol A (BPA), an industrial chemical used to make certain plastics and resins, inner coatings for food cans and bottle tops, thermal paper used in store receipts, dental sealants and so on, is a concern because of possible adverse health effects, including a reduction in fertility.
Can staying up late make you fat? A growing body of research has suggested that poor sleep quality is linked to an increased risk of obesity by deregulating appetite, which in turn leads to more calorie consumption.
Nagoya University researchers and colleagues have revealed the nerve circuitry regulating the response of a tiny soil worm to changing temperatures.
While many of us worry about proteins aggregating in our brains as we age and potentially causing Alzheimer's disease or other types of neurodegeneration, we may not realize that some of the same proteins are aggregating in our muscles, setting us up for muscle atrophy in old age.
The model will permit to accelerate and reduce the price of the research, which is studying the mechanisms and the possible pharmacological targets for the neuronal alterations of this disease.
From plastics to pesticides, it seems like every week delivers fresh news about the dangers of endocrine disruptors--chemicals in the environment that alter the body's hormones and can lead to reproductive, developmental, neurologic and immune problems and cancer.
One common gut organism that helps us digest food better could also be a powerful instrument in preventing or reversing the symptoms of Parkinson’s disease (PD), according to a recent study. The changes are due to the ability of this bacterium to delay the build-up of a toxic protein involved in this in the disease condition, or even to eliminate the toxin altogether.
Researchers at Worcester Polytechnic Institute have developed a tool to identify molecular receptors in worms that are involved in sensing pheromones related to mating, an advance that could speed up neuroscience research into pheromones by eliminating months of work.
Researchers at Harvard Medical School and the New York State Department of Health have discovered how a common plasticizer associated with human reproductive abnormalities likely does its damage at the molecular level.
Uniting structure and function of synapses is challenging: Function is studied in living tissue, measuring electrical signals at millisecond precision with electrophysiology, while the observation of fine structure at nanometer scale requires tissue to be fixed for electron microscopy.
A study by researchers in the United States and India has shown that probiotic yeasts derived from food are able to reduce the virulence of, and even prevent infections by, several types of fungi that are responsible for life-threatening infections in hospitalized and immune-compromised individuals, including the multi-drug resistant Candida auris, which was recently listed as an urgent threat by the U.S. Centers for Disease Control in its 2019 Antibiotic Resistance Threats report.
Insights from their study may provide a novel therapeutic approach for diseases such as Huntington's and Parkinson's.
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.
