Phys.org / Australian freshwater fish like to dine out, relying on land-based food sources
New research has found that roughly half of Australia's freshwater fish are fond of snacking on animal and plant material, including fruits, from outside their aquatic habitats.
Phys.org / Long-term pesticide exposure accelerates aging and shortens lifespan in fish
Long-term exposure to low levels of a common agricultural pesticide can accelerate physiological aging and shorten lifespan in fish—a finding from new research led by University of Notre Dame biologist Jason Rohr with potentially ...
Phys.org / Chemists determine structure of fuzzy coat that surrounds Tau proteins
One of the hallmarks of Alzheimer's disease is the clumping of proteins called Tau, which form tangled fibrils in the brain. The more severe the clumping, the more advanced the disease is.
Medical Xpress / Influence of dog ownership on exercise self-efficacy and physical activity: Differences before and after COVID-19
Researchers at University of Tsukuba examined how dog ownership and exercise self-efficacy affected physical activity among Japanese office workers before, during, and after the COVID-19 pandemic.
Medical Xpress / Discovery reveals how keto diet can prevent seizures when drugs fail
University of Virginia School of Medicine researchers have revealed how the popular, low-carb ketogenic diet protects against epilepsy seizures and possibly neurodegenerative diseases such as Alzheimer's and Parkinson's.
Medical Xpress / Living for today in disaster's wake: Exploring why risky behavior surged after 2011 tsunami and earthquake
When Ichiro Kawachi established a cohort study in Iwanuma, Japan, in 2010, he thought he would be researching the predictors of healthy aging.
Tech Xplore / AIs behaving badly: An AI trained to deliberately make bad code will become bad at unrelated tasks, too
Artificial intelligence models that are trained to behave badly on a narrow task may generalize this behavior across unrelated tasks, such as offering malicious advice, suggests a new study. The research probes the mechanisms ...
Medical Xpress / Dormant cancer cells can change shape to survive immune system attack
Cancer cells that have broken away from a primary tumor can lurk in the body for years in a dormant state, evading immune defenders and biding their time until conditions are ripe for establishing a new tumor elsewhere in ...
Phys.org / Glazed sherds in remote Gobi Desert reveal ancient Persian trade connections
In a study published in the Journal of Archaeological Science: Reports, Dr. Ellery Frahm and his colleagues analyzed two unusual blue-green glazed ceramic sherds discovered in the Gobi Desert in 2016.
Phys.org / Ocean impacts nearly double economic cost of climate change, study finds
For the first time, a study by researchers at Scripps Institution of Oceanography at the University of California, San Diego integrates climate-related damages to the ocean into the social cost of carbon—a measure of economic ...
Phys.org / Same moves, different terrain: How bacteria navigate complex environments without changing their playbook
Just like every other creature, bacteria have evolved creative ways of getting around. Sometimes this is easy, like swimming in open water, but navigating more confined spaces poses different challenges.
Phys.org / Hybrid polymer nanocarriers improve pulmonary mRNA vaccine delivery
An LMU research team led by Professor Olivia M. Merkel, Chair of Drug Delivery at LMU, has developed a new delivery system for inhalable mRNA vaccines. Published in the journal Cell Biomaterials, the study presents a novel ...
