- Why are the offspring of older mothers less fit to live long and prosper? July 2, 2020In a new study in rotifers (microscopic invertebrates), scientists tested the evolutionary fitness of older-mother offspring in several real and simulated environments, including laboratory culture, under threat of predation in the wild, or with reduced food supply. They confirmed that this effect of older maternal age, called maternal effect senescence, does reduce evolutionary fitness of […]
- Marine algae from the Kiel Fjord discovered as a remedy against infections and skin cancer July 2, 2020Using state-of-the-art approaches coupled with bio- and cheminformatics and machine learning, researchers have succeeded in discovering new, bioactive components of the Baltic Sea Baltic Sea seaweed Fucus vesiculosus and its fungal symbiont against infectious bacteria or skin cancer.
- Does deep brain stimulation for Parkinson's increase risk of dementia? July 1, 2020There's good news for people with Parkinson's disease. A new study shows that deep brain stimulation may not increase the risk of developing dementia.
- A simpler way to make sensory hearing cells July 1, 2020Scientists are whispering the secrets of a simpler way to generate the sensory cells of the inner ear. Their approach uses direct reprogramming to produce sensory cells known as 'hair cells,' due to their hair-like protrusions that sense sound waves.
- Why do arteries age? Study explores link to gut bacteria, diet July 1, 2020Eat a slab of steak and your resident gut bacteria get to work immediately to break it down. But new research shows that a metabolic byproduct, called TMAO, produced in the process can be harmful to the lining of arteries, making them age faster.
- Plasticity may make neurons vulnerable to Alzheimer's disease June 29, 2020Neurons that regularly remodel are more prone to the dysfunctions linked to the disease's onset, a new experimental and computational study finds.
- New research paves way for developing therapies that could slow down Alzheimer's June 29, 2020Neuroscientists and stem cell researchers have developed a research model that allows studying human hippocampal neurons, the brain cells primarily affected by Alzheimer's disease pathology.
- Repeated head impacts associated with later-life depression symptoms, worse cognitive function June 26, 2020In the largest study of its kind, an association has been found in living patients exposed to repetitive head impacts and difficulties with cognitive functioning and depression years or decades later.
- Scientists devise new 'bar code' method to identify critical cell types in the brain June 25, 2020A discovery could pave the way for future studies aimed at developing solutions to ALS and other vexing neuromuscular diseases.
- Receptor makes mice strong and slim June 25, 2020Increasing abdominal girth and shrinking muscles are two common side effects of aging. Researchers have discovered a receptor in mice that regulates both effects. Experiments with human cell cultures suggest that the corresponding signaling pathways might also exist in humans.
