A new instrument aboard NASA’s Europa Clipper may be sensitive enough to detect any life emanating from the plumes of far-off icy moons like Saturn's Enceladus and Jupiter's Europa. Over the years, scientists have found evidence of water underneath both moon’s frozen surfaces.The instrument dubbed the SUrface Dust Analyzer (SUDA) on the Europa Clipper, can detect even the slightest biological signatures in one out of hundreds of thousands of grains of ice from plumes on Europa and Enceladus. ...read more
Airplane flight is one of the most significant technological achievements of the 20th century. The invention of the airplane allows people to travel from one side of the planet to the other in less than a day, compared with weeks of travel by boat and train.Understanding precisely why airplanes fly is an ongoing challenge for aerospace engineers, like me, who study and design airplanes, rockets, satellites, helicopters and space capsules.Our job is to make sure that flying through the air or in ...read more
If you don’t live in Australia, you may never have seen a numbat — even if you do, you may still have never seen one. The numbat is small, well-camouflaged, and … there aren’t many to see. That’s because they’re endangered. Though its territory once covered most of the bottom half of Australia, from the west of New South Wales to Western Australia, the numbat is now limited to two indigenous populations in southwest Western Australia (Dryandra National Park and the Upper Warren regi ...read more

By harnessing light, my colleagues and I designed a wireless, ultrathin pacemaker that operates like a solar panel. This design not only eliminates the need for batteries but also minimizes disruptions to the heart’s natural function by molding to its contours. Our research, recently published in the journal Nature, offers a new approach to treatments that require electrical stimulation, such as heart pacing.Pacemakers are medical devices implanted in the body to regulate heart rhythms. They†...read more
