Joseph Sobanko's patients often ask him which sunscreen is best. That's especially true this time of year, when people are going outside and the sun's rays are at their brightest - and most damaging. Whether the patient is blond or dark, freckled or fair, the Penn Medicine skin-cancer specialist has the same answer: Whichever sunscreen you'll actually use. Far too few of us do, he says. About one in five Americans will develop skin cancer - the most common kind of cancer - in their lifetimes.

BECAUSE OF HIS almost-forever fascination with the earth and sky, Marc Berlanger plans to major in geoscience at Bloomsburg University. Did someone say earth and sky? Thursday, those words were quite the fit for Berlanger's first two at-bats in an important Catholic Red baseball game. In both, he drove deep fly balls toward almost the exact same part of dead rightfield. The first launching offered momentary hope, then returned him to earth. The second sent him soaring sky high!

THE DOCUMENTARY "No Place on Earth" doesn't seem as if it should work quite as well as it does. A History Channel production, the tale of Ukrainian Jews who survived in underground caves for 511 days while hiding from the Nazis during World War II is structured around lengthy, foreign-language re-enactments of the events featuring costumed performers. Why not just commit to the undeniably thrilling theatricality of the story and make a fictionalized dramatic feature? Instead, Emmy-winning documentarian Janet Tobias ("Life 360")

By Derrick H. Pitts Considering the recent close calls our planet has had with various asteroids, meteors, and comets, it's time to develop an early-warning system - a cosmic "heads up" - to detect the wanderers zooming through the solar system. The major concern, of course, is whether any of these space travelers is on a collision course with Earth. Our geologic record clearly indicates that not only have we been hit before, but in one instance, the object was large enough to significantly change the planet's environment, triggering the demise of the dinosaurs about 65 million years ago. If they couldn't survive an impact, what chance would mere humans have to survive?

CAPE CANAVERAL, Fla. - Now's your chance to see the comet that passed within 100 million miles of Earth last week. Twilight on Tuesday will provide the best photo op for Pan-STARRS. It will be visible in the Northern Hemisphere just above the western horizon - right next to a crescent moon. California astronomer Tony Phillips said the glare of the setting sun may make it difficult to see the comet with the naked eye. But he encourages casual sky gazers to give it a shot. The moon will provide an easy point of reference.

LOS ANGELES - In a Mars first, the Curiosity rover drilled into a rock and prepared to dump an aspirin-size pinch of powder into its onboard laboratories for closer inspection. The feat marked yet another milestone for the car-size rover, which landed last summer to much fanfare on an ambitious hunt to determine whether environmental conditions were favorable for microbes. Using the drill at the end of its 7-foot-long robotic arm, Curiosity on Friday chipped away at a flat, veined rock bearing numerous signs of past water flow.

An asteroid half the size of a U.S. football field will dart between Earth and orbiting satellites next week, sparing the human race and putting on a show for sky gazers in Eastern Europe, Asia, and Australia, NASA said. The 150-foot-diameter asteroid, named 2012 DA14, will pass about 17,000 miles above Earth on Friday - lower than the orbits of some satellites - in the closest-known approach of an object of its size. It will travel at 7.8 kilometers a second (17,400 miles an hour), or about eight times the speed of a rifle shot, NASA scientists said.
