What’s the difference between physics and biology? Take a golf ball and a cannonball and drop them off the Tower of Pisa. The laws of physics allow you to predict their trajectories pretty much as accurately as you could wish... Continue Reading →
Massachusetts General Hospital (MGH) investigators have developed a novel approach to analyze brainwaves during sleep, which promises to give a more detailed and accurate depiction of neurophysiological changes than provided by a traditional sleep study. In a report published in... Continue Reading →
Juno just completed its fourth pass near Jupiter. Launched from Earth in 2011 and arriving at Jupiter just last July, robotic Juno concluded its latest elliptical orbit around our Solar System's largest planet 11 days ago. Pictured here from that... Continue Reading →
Peering from the shadows, the Saturn-facing hemisphere of tantalizing inner moon Enceladus poses in this Cassini spacecraft image. North is up in the dramatic scene captured last November as Cassini's camera was pointed in a nearly sunward direction about 130,000... Continue Reading →
Chemical recalibration of brain cells during sleep is crucial for learning, and sleeping pills may sabotage it. Studying mice, scientists at Johns Hopkins have fortified evidence that a key purpose of sleep is to recalibrate the brain cells responsible for... Continue Reading →
Earth’s atmosphere may have been leaking oxygen onto the moon for billions of years. Energetic particles from the solar wind bombard the moon nearly all time, except for a five-day window each month, when Earth passes between the sun and... Continue Reading →
Specific brain regions, including those involved in awareness of self and tendency to ruminate, show altered activity in patients with insomnia when compared to good sleepers, according to a new study by researchers at the University of Pittsburgh School of... Continue Reading →
One of the differences between adults and preschoolers when it comes to private speech is that adults typically talk to themselves in their heads, while preschoolers talk to themselves aloud, particularly while playing or working on a task. Private speech... Continue Reading →
Most women experience hot flashes and night sweats either before or during menopause, but a significant minority don’t have these symptoms. Could our genes be a factor in determining which women get hot flashes? A team of UCLA-led researchers may... Continue Reading →
