Grace expects Greinke trade to have emotional impa

first_img Grace expects Greinke trade to have emotional impact Top Stories Outside of them, the bulk of Arizona’s starters is considered to be either “average,” “below average” or “poor,” though only receiver Andre Roberts grades out in the latter group. – / 36 The 5: Takeaways from the Coyotes’ introduction of Alex Meruelo Former Cardinals kicker Phil Dawson retirescenter_img Comments   Share   In a piece meant to judge every team’s starting units, the Cardinals are noted to have just nine players who are above average.Wide receiver Larry Fitzgerald, not surprisingly, is regarded as a “difference maker,” as is defensive end Calais Campbell. Linebacker Daryl Washington and cornerback Patrick Peterson are said to be “high quality,” while quarterback Carson Palmer, running back Rashard Mendenhall, tackle Bobby Massie, linebacker Karlos Dansby and defensive tackle Dan Williams are considered “good.”– I’ve given both Palmer and Mendenhall the benefit of the doubt respectively due to the former working in a more conducive environment, and the latter being healthy.– I’m viewing Bobby Massie more on the second half of his season than the first, but did consider both.– Before Dockett gets an upgrade he needs to show something and not just talk about how badly Ray Horton’s scheme affected him — it hardly slowed Campbell did it? Derrick Hall satisfied with D-backs’ buying and selling The Arizona Cardinals spent an entire offseason trying to remake a roster that won just five games last season.While it’s too early to know for sure, the offense and defense figure to have at least nine new starters compared to the group that finished last season, and the hope is each will present a significant upgrade.But according to ProFootballFocus.com’s Neil Hornsby, the roster is not exactly littered with top-notch talent.last_img read more

Stink bugs protect their eggs by changing their color

first_imgNewspaper lining the bottom of a stink bug (Podisus maculiventris, pictured, with eggs at bottom) cage may seem an unlikely impetus for scientific discovery, but it was the black and white squares of the crossword puzzle that that led Paul Abram, an entomologist working towards his Ph.D. at Université de Montréal in Canada, to suspect that stink bugs might be employing a surprising strategy when laying their eggs. Plenty of animals, like birds and other insects, lay eggs that differ in color based on what their parents eat or other factors, but scientists have never observed mothers intentionally changing the color of their eggs. Abram noticed that the eggs on the dark squares tended to be darker and vice versa. Although camouflage might be a tempting explanation for the phenomenon, subsequent experiments, in which the stink bugs were given only white fabric to lay their eggs on, revealed that the pigments served a different function. According to research published today in Current Biology, female stink bugs can change the color of their eggs depending how much light is reflecting off a surface by selectively adding a dark pigment. Because of the pigment’s ability to absorb UV light, the researchers believe that its function is to protect the delicate DNA and cellular machinery inside the developing bug. Abram likens it to sunscreen. In the wild stink bugs lay their eggs on leaves, and additional experiments showed that the bugs placed darker eggs on the top (in direct sunlight), whereas eggs on the shaded underside of the leaf contained 2.1 times less pigment on average. The identity of the pigment is still unknown, but early experiments suggest that it may be related to melanin—the most abundant dark pigment on the planet.last_img read more
