Medical Xpress / Alzheimer's disease can be evaluated with brain stimulation, finds study

As individuals with Alzheimer's disease (AD) move from the mild cognitive impairment stage to moderate and severe dementia, complex awareness deteriorates although lower-level sensory awareness is relatively maintained. Most ...

Phys.org / Rewilding corn reveals what its roots forgot

Corn is a colossal grain in the global food and feed chain, with the U.S. producing roughly 30% of the world's supply, or nearly 278 million metric tons in the 2024–25 growing season alone. But its journey from wild grass ...
