The global cobalt supply chain is more interconnected—and more vulnerable—than previously thought, with disruptions capable of triggering far-reaching cascades across multiple countries and industries。 Researchers warn that protecting battery supply chains will require system-wide coordination because critical bottlenecks can turn local shocks into
Could something as simple as vitamin C help support a healthier aging brain。 In a study of more than 2,000 older adults in Japan, researchers found that people with lower vitamin C levels in their blood also tended to have less gray matter and weaker connections in a key brain network involved in memory, attention, and other cognitive functions
Fish oil supplements successfully delivered omega-3s to the brain, but a two-year study found no meaningful benefits for memory, cognition, or Alzheimer’s-related brain changes。 The results challenge the idea that fish oil pills can help prevent Alzheimer’s and shift attention toward overall diet and lifestyle instead
Vitamin B12 is needed in microscopic amounts, but a shortage can have major effects on health and energy。 The vitamin was first linked to a lifesaving liver treatment for pernicious anemia nearly 100 years ago。 Today, researchers are finding that B12 may also help keep cellular powerhouses called mitochondria functioning properly
Researchers found that highly drug-resistant bacteria from hospitals are also resistant to glyphosate, a commonly used weedkiller。 The discovery suggests that agricultural herbicides may be helping antibiotic-resistant microbes survive and spread far beyond healthcare settings
A common brain protein may be giving Alzheimer’s disease an unexpected way to spread, carrying toxic Tau proteins from damaged neurons into healthy ones。 By blocking these harmful protein packages before they reach new cells, researchers believe it may one day be possible to slow the disease's relentless progression
Researchers have discovered that beneficial soil bacteria give plants an unexpected survival advantage in salty soils。 Instead of helping plants keep salt out, the microbes stimulate the production of lignin, a natural compound that strengthens roots and makes plants more resilient。 Greenhouse and field tests showed healthier plants and higher yiel
Humans evolved to pay close attention to danger, but today that instinct is being overwhelmed by an endless supply of bad news from around the world。 Researchers say the answer isn’t to stop following current events—it’s to build healthier habits around how, when, and where we get our news
Scientists discovered that Heliconius butterflies have evolved an extraordinary lifespan, living several times longer than closely related species。 Even more surprising, some show little sign of physical decline as they age。 Their unusual pollen-feeding lifestyle may play a role, but the research suggests deeper evolutionary changes are also helpin
