Cannabis products with higher THC levels may slightly reduce chronic pain, particularly nerve pain, according to a review of multiple clinical trials. The improvement was small and short-lived, while side effects were more common. Products with ...
New research shows that women living near Superfund sites are more likely to develop aggressive and metastatic breast cancers. The studies found higher risks for hard-to-treat subtypes like triple-negative breast cancer, especially in areas with ...
Environmental change doesn't affect evolution in a single, predictable way. In large-scale computer simulations, scientists discovered that some fluctuating conditions help populations evolve higher fitness, while others slow or even derail progress. ...
A spectacular fossil trove on the Arctic island of Spitsbergen shows that marine life made a stunning comeback after Earth's greatest extinction. Tens of thousands of fossils reveal fully aquatic reptiles and complex food chains thriving just three . ...
Thanks to Einstein's relativity, time flows differently on Mars than on Earth. NIST scientists have now nailed down the difference, showing that Mars clocks tick slightly faster--and fluctuate over the Martian year. These microsecond shifts could ...
Scientists have uncovered an extensive underwater vent system near Milos, Greece, hidden along active fault lines beneath the seafloor. These geological fractures act as pathways for hot, gas-rich fluids to escape, forming clusters of vents with ...
A new randomized trial from Vanderbilt-Ingram Cancer Center reveals that magnesium may be the missing key to keeping vitamin D levels in balance. The study found that magnesium raised vitamin D in people who were deficient while dialing it down in .. ...
As the immune system weakens with age, scientists have found a way to restore some of its lost strength. By delivering mRNA to the liver, they created a temporary source of immune-boosting signals that normally come from the thymus. Older mice ...
The Arctic is changing rapidly, and scientists have uncovered a powerful mix of natural and human-driven processes fueling that change. Cracks in sea ice release heat and pollutants that form clouds and speed up melting, while emissions from nearby . ...
Researchers have created a protein that can detect the faint chemical signals neurons receive from other brain cells. By tracking glutamate in real time, scientists can finally see how neurons process incoming information before sending signals ...
