Being home more during the pandemic, and with less traffic on the roads from stay-at-home orders, many people have heard more bird calls and the sounds of nature in urban areas. Scientists now say at least one bird species has been able to adjust their bird song because of the lack of human noise to compete with.Researchers have been studying the white-crowned sparrows in and around San Francisco for more than two decades. They compare their songs in recent years with recordings made in the 1970s.They found as traffic levels increased over the decades, the lowest frequencies of the sparrows’ song rose. This allowed their song to be heard above the low hum of vehicles. The top frequencies remained the same, so the total frequency bandwidth of their communication was narrowed.Degrading their songs this way, and limiting their range, makes them less effective at deterring rivals, attracting mates, or hearing their own chicks, according to researchers. In noisy environments, birds have to sing louder, which research has shown can result in stress and can speed up a bird’s aging and disrupt their metabolisms.When stay-at-home orders and coronavirus pandemic safety measures were put in place in March, the lead researcher, Elizabeth Derryberry, remembers seeing an image of the Golden Gate Bridge in San Francisco completely empty of cars or humans. She wondered how the sparrows were responding.They compared audio recordings of the bird songs from spring 2015 and 2016, to those taken this spring. The recordings were made in a variety of urban and rural locations around the greater San Francisco area.“We found that birds sung at lower minimum frequencies, achieving greater bandwidth songs in newly open acoustic space. An increase in frequency bandwidth results in the transmission of more information and greater vocal performance,” the study states.The samples taken in 2020 revealed the white-crowned sparrows had changed their tune, so-to-speak, and were singing softer and using a wider range of frequencies. They also were able to communicate twice as far as previous recordings.“This doubling in communication distance could elevate fitness by reducing territorial conflicts and increasing mating potential,” researchers stated.Researchers also say this explains why more people report hearing birds during the pandemic. Since the songs are traveling farther distances, humans are able to hear more of them.They also say the changes in the birds’ songs were more pronounced in urban areas compared to the rural location samples. This would make sense, they say, because the traffic noise did not change as drastically in the rural locations during the pandemic.“Our findings indicate that songbirds like white-crowned sparrows have a striking capacity to exploit newly empty soundscapes following acute but ephemeral amelioration of noise pollution, suggesting that lasting remediation might engender even more promising outcomes, such as demographic recovery and higher species diversity in urban areas,” they concluded. 3055

  

Barbie dolls have long inspired young girls with their beauty and fashion sense. Now they're inspiring them with their brains and bravado, too.On Tuesday, just ahead of International Women's Day, Barbie introduced a batch of new dolls based on real-life figures.The new dolls came after Mattel, maker of Barbie, conducted a survey of 8,000 mothers around the globe and found that 86% are worried about the kind of role models their daughters are exposed to."Girls have always been able to play out different roles and careers with Barbie and we are thrilled to shine a light on real life role models to remind them that they can be anything," wrote Lisa McKnight, senior vice president and general manager of Barbie, in a news release.This week Mattel introduced dolls in two separate series of Barbies: "Inspiring Women," based on historical figures, and new additions to its "Shero" line of dolls named for inspirational contemporary women.Both lines reflect the Barbie brand's highest honor: a one-of-a-kind doll made in a real woman's likeness.Inspiring WomenThe "Inspiring Women" dolls come with educational information about the contributions each woman made to society.One is Amelia Earhart, the first female aviator to fly across the Atlantic Ocean. Frida Kahlo, the renowned Mexican artist and activist, will be another.Barbie will also honor Katherine Johnson, a pioneer in mathematics who broke barriers of race and gender. One of the characters in the hit movie "Hidden Figures," Johnson was among a pool of women hired by NASA to work as human "computers" for the first US-manned flight into space.Although the "Inspiring Women" series only has three dolls so far, it will grow with the release of new dolls, said Marissa Beck, spokeswoman for Mattel."The Inspiring Women Series pays tribute to incredible heroines of their time; courageous women who took risks, changed rules, and paved the way for generations of girls to dream bigger than ever before," Beck wrote in an email to CNN.SheroesBarbie's "Shero" program began in 2015 to highlight real women who have broken boundaries in their field.This week, Barbie released 14 new Shero dolls, including ones based on "Wonder Woman" director Patty Jenkins and US snowboarder Chloe Kim, who just won a gold medal at the 2018 Winter Games in Pyeongchang. Other Shero dolls honor fashion designers, journalists, actresses and entrepreneurs.These Sheroes include honorees from the United States, Australia, United Kingdom, Turkey, France, China, Germany, Mexico, Poland, Italy and Spain, Beck said.The dolls will start to roll out to stores nationwide soon but are currently for pre-sale now on the Barbie website.The-CNN-Wire? & ? 2018 Cable News Network, Inc., a Time Warner Company.

Bruises, loss of vision or the loss of an eye – injuries during protests have drawn more attention to what police call "non-lethal" tools.An expert tells us there are certain categories: Chemical weapons like tear gas, electric devices like Tasers, impact weapons like batons, and kinetic impact munitions, meaning any fire projectiles, including bean bag rounds.“You tend to see grenade launchers being used in crowd control, more than anything else,” said Charlie Mesloh, a professor of criminal justice at Northern Michigan University. “Also, you're going to see shotguns only because they're plentiful and they're, you know, they're accurate.”Mesloh is also a former officer who has conducted research on these weapons. He says what many people have started calling “rubber bullets” are actually skip-fired munitions. Those are the most concerning to him because they're less predictable.Skip-fired munitions are typically shot out of a grenade launcher with a few rounds inside. They're meant to be bounced off the ground to cut down on some of the sting.Mesloh says that after looking at pictures of injuries, he thinks some are being fired directly at people.“There are some problems and with how these are being used, some of them might be training,” said Mesloh. “Some of them also could be more environmental. They're like, they're wearing a gas mask and they can't see.”Mesloh says there's no reason police should ever be shooting someone in the head, unless they're trying to kill them. 1506
