After allowing just over 26 points per game in the team’s first three contests, the Cardinals have limited their last two opponents to 16 points combined, and both games have resulted in wins.For head coach Bruce Arians, that’s exactly what he had in mind when taking over the Cardinals, saying he supports being known as a defensive-first team. “I love it,” Arians said. “That’s always been my motto and we want to be dominant on defense. We’ll scratch some points out, but we always want to be a dominating defensive football team.”Star cornerback Patrick Peterson, who has three interceptions on the year, agrees with that mentality.“The saying always stands true: ‘Defense wins championships,’” Peterson said. “If we want to be a good ball club, our defense must be strong.”The Cardinals are coming off a strong defensive year in 2012, but a tough schedule, inactive players and getting used to a new coaching staff might have hidden the true talent level of the group. With tough matchups coming up in the next two weeks, against San Francisco and Seattle, Arians remains confident in his defense.“I think our defense matches up with everybody,” Arians said. “We’ve got good speed. We’re starting to understand the defense better each week.”last_img read more

Five genes that give your nose its shape

first_imgWhether you have a huge honker, a puny proboscis, or a snubbed schnoz, the shape of your nose is in your genes. Now, researchers have sniffed out five of those stretches of DNA that control nose and chin shape. The team sequenced the genomes of more than 6000 men and women in Central and South America and used photographs of the participants to categorize 14 of their facial features—from cheekbone protrusion to lip shape. Then, the scientists analyzed whether any of the features were associated with certain genes. GLI3 and PAX1, both known to be involved in cartilage growth, were linked to the breadth of a person’s nostrils; DCHS2, also related to cartilage, controlled nose pointiness; RUNX2, which drives bone development, was associated with the width of the nose bridge, the upper area of the nose; and EDAR, which has previously been linked to ear and tooth shape and hair texture, affected chin protrusion. The results, published online today in Nature Communications, may help shed light on how the human face evolved and why different ethnicities have distinct facial features. Moreover, the research could help forensic scientists reconstruct faces based on genetic samples.last_img read more
