Cannabis-based medicines have been widely promoted as a potential answer for people living with chronic nerve pain--but a major new review finds the evidence just isn't there yet. After analyzing more than 20 clinical trials involving over 2,100 ...

Scientists have discovered that breast cancer can quietly throw the brain's internal clock off balance--almost immediately after cancer begins. In mice, tumors flattened the natural daily rhythm of stress hormones, disrupting the brain-body feedback ...

Solid-state batteries could store more energy and charge faster than today's batteries, but they tend to crack and fail over time. Stanford researchers found that a nanoscale silver treatment can greatly strengthen the battery's ceramic core. The ...

While social media continues to circulate claims linking acetaminophen to autism in children, medical experts say those fears distract from a far more serious and proven danger: overdose. Acetaminophen, found in Tylenol and many cold and flu remedies ...

A huge bar of iron has been discovered lurking inside the iconic Ring Nebula. The structure is enormous, spanning hundreds of times the size of Pluto's orbit and containing a Mars-sized amount of iron. It was detected using a new instrument that ...

When scientists sent bacteria-infecting viruses to the International Space Station, the microbes did not behave the same way they do on Earth. In microgravity, infections still occurred, but both viruses and bacteria evolved differently over time. .. ...

A Michigan dairy farm took a gamble on a new kind of soybean--and it paid off fast. After feeding high-oleic soybeans to their cows, milk quality improved within days and feed costs dropped dramatically. Backed by years of MSU research, the crop is . ...

A long-running Swedish study has followed adults for nearly five decades, uncovering when physical decline truly begins. Fitness and strength start slipping around age 35, then worsen gradually with age. The encouraging twist: adults who began ...

Tiny plastic particles drifting through the oceans may be quietly weakening one of Earth's most powerful climate defenses. New research suggests microplastics are disrupting marine life that helps oceans absorb carbon dioxide, while also releasing .. ...

Engineers have created a device that generates incredibly tiny, earthquake-like vibrations on a microchip--and it could transform future electronics. Using a new kind of "phonon laser," the team can produce ultra-fast surface waves that already play ...
