BUENOS AIRES - Argentinian police officers were fired after they claimed that mice ate more than half a ton of marijuana that was not accounted for in the police warehouse.After an inspection, an officer noticed 540kg of cannabis was missing the confiscation warehouse just outside of Buenos Aires.During a span of two years of storage, police collected 6,000 kg of marijuana. At the time, Javier Specia was the police commissioner.According to The Guardian, Specia stepped down in April 2017 and was replaced with Commissioner Emilio Portero. Portero noticed only 5,460 kg of marijuana in the warehouse.When questioned by a judge, Specia and three of his subordinate officers all claimed that the missing drugs were "eaten by mice."Experts found the claim to be impossible.“Buenos Aires University experts have explained that mice wouldn’t mistake the drug for food, and that if a large group of mice had eaten it, a lot of corpses would have been found in the warehouse,” said a spokesperson for the judge.On May 4 the officers will testify in court to see if the missing narcotics were due to "expedience or negligence."There is no statement from Specia at this time, but the ex-commissioner faces further internal investigation. 1265

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

Britain's Prince Charles has released a candid family photograph, as the heir to the throne celebrates his 70th birthday.In a special edition of British magazine Country Life, which the Prince of Wales guest-edited to mark the occasion, he spoke of "the alarming realization that I have reached the biblical threshold of three score years and 10."However, in the official portrait, taken in the gardens of Clarence House in London in September, Charles looks anything but alarmed.The future king seems relaxed as he holds his eldest grandson, Prince George, on his lap, surrounded by members of his immediate family.It's been five years since Charles last stepped in as guest editor for Country Life, and this edition offers even greater insight into the royal's life and his views on the British countryside.An interview with his eldest son William, the Duke of Cambridge, reveals that Charles, a long-time advocate of environmental issues such as climate change, is "completely infatuated" by the endangered red squirrels and has "hundreds" of bird tables at his Highgrove estate in England, which he replenishes by hand whenever he is there.The prince also commissioned his wife, the Duchess of Cornwall, to write about her support for the Medical Detection Dogs charity. 1282

Behind every stitch and each piece of fabric on the dolls put on display in Washington D.C., there’s a real face and a real story.Activist Marta Perez-Garcia is the creator of the display, and she hopes it will open the public’s eyes to the realities surrounding domestic violence.“I think, because I have too many people around me and I really saw it for so long, I needed to do something about it,” Perez-Garcia says.Perez-Garcia grew up in Puerto Rico and says she regularly witnessed women being abused. She says after moving to the mainland U.S., those stories didn’t stop."It's something that is in the media, that you see that is very close to home,” she says."One in 3 women are survivors of domestic violence and or sexual assault,” says Bakht Arif, who works with abuse survivors. “And that is a lot of people.Arif works with abuse survivors for a non-profit project in Washington D.C. She believes the doll display is one way to grab people's attention but says the conversation should go far beyond this.“Policy is important; legislation is important,” Arif says. “And we will be cheering and protesting for it and cheering for anyone who supports it and brings light to the issue.”The exhibit at the Franklin Reeves building in Washington D.C. was on display throughout the month of October to promote awareness.  But Perez-Garcia says the real voices for change will come from voters in November. "As society, we have to do something about this issue,” she says. “So, if it's to really take people in power to really make the right decisions against domestic violence, of course we have to do that.” 1631
