Growing Stem Cells in Space to Improve Cancer and Disease Treatments

One in six internet-using children from a survey of nearly 12,000 children in 12 countries across Asia and Africa are found to experience at least one form of technology-facilitated sexual exploitation and abuse, with many experiences undisclosed, according to research published in Nature. The findings may help to inform prevention and response efforts where coordinated action by policymakers, law enforcement, and technology companies is urgently needed to protect children.

From Australia's remote deserts to the surface of Mars, geological mapping underpins how we understand landscapes, natural resources, and the processes that shape our planet and others beyond it.

In a grandfather clock, a pendulum swings back and forth and this periodic motion is maintained using the energy stored in its suspended weights. This is done with the help of the escapement mechanism, which converts the gravitational energy of the weights into impulses that drive the pendulum, which then moves the clock's gears, which move its hands.

Nearly 50 years ago, a puzzling earthquake beneath northern Utah jolted scientists' understanding of how Earth works. Now, research from the University of Utah confirms that the mysterious event was real, and part of a rare class of earthquakes occurring far deeper beneath the continental crust than scientists once believed possible.
