Researchers from the University of Roehampton in London and the University of Sydney found that kangaroos know how to communicate with humans if they need help.According to the study published in the journal Biology Letters on Wednesday, out of the 11 kangaroos researched, 10 of them gazed at researchers when they were unable to access food during an unsolvable task. Out of those 10, nine of the marsupials would alternate their gaze from the object to the human.In some cases, researchers said, the kangaroos would sometimes even nudge or scratched them to ask for help, said co-author Alexandra Green, according to the University of Sydney.Before the study, researchers thought that only domesticated animals, like dogs, cats, wolves, horses, and sometimes goats, were capable of communicating with humans with an enhanced form of communication.Officials said the study's kangaroos were from various zoos in Australia and are familiar with people but are not considered domesticated. 996

Raising the age of cigarette purchasing from 18 to 21 could have massive impacts on youth smoking. "This would be the number one thing I would do in New York state," Roswell Park Health Behavior Chair Dr. Andrew Hyland said. According to Hyland, if the age were to go up three years, the number of young smokers would decrease. "If you raise the age from 18 to 21 we're going to see 25% fewer kids becoming cigarette smokers" Hyland said. There would be less smokers due to the fact that 18 year old brains are still in development. Hyland says it would be unlikely for someone to just start smoking at 21 as opposed to 18 or 19. < 667

Republicans officially nominated President Donald Trump for re-election Monday during an in-person roll call vote at the Republican National Convention in Charlotte.Trump cruised to victory in the GOP primary, as is typical for an incumbent president in a re-election primary. Trump picked up nearly every available delegate in his campaign, losing just a single delegate to former Massachusetts Gov. Bill Weld.The roll call vote was one of the few in-person events scheduled for the four-day RNC. Prior to the pandemic, Charlotte was scheduled to host all events relating to the convention, but Trump later said he would move portions of the convention to Jacksonville, Florida, citing North Carolina Gov. Roy Cooper's hesitancy to lift lockdown restrictions. Trump later canceled the Florida portions of the RNC as cases and deaths in the state spiked.Democrats held a completely virtual convention last week, which included an entirely remote roll-call vote.The nightly programming of the RNC begins on Monday evening at 8:30 p.m, with politicians and other prominent Republicans giving speeches from across the country. Monday's program will be headlined by Donald Trump Jr. and Sen. Tim Scott (R-South Carolina). 1225

RAMONA (KGTV) - — The owner of Ramona Fitness Center is trying to rally business owners to stand up for their rights and consider defying San Diego County public health orders that require many businesses to close.“They’re forcing us out of business," Peter San Nicolas told ABC 10News in an interview Tuesday. "They’ll force people to not be able to pay for food and pay for home, for somewhere to live. We’re talking about basic necessities and they’re pushing us to the limit.”Gyms are among the sectors ordered to cease all indoor operations after the county moved into the state's purple, or worst, tier. This comes as the county recorded 1,546 new COVID-19 cases Tuesday, a single-day record.San Nicolas makes the case that gyms can open safely and that forcing them to close will not stop the spread. “We haven’t had any issue with it here in the gym. We’ve had over 25,000 check-ins just since June and we’ve had no cases of covid here at the gym.”According to the latest outbreak numbers on the county website, only 0.4% of all cases recorded between June 5 and November 14 have been tied to gyms. However, many public health experts say there is no question gyms should be closed during this most recent surge. "Gyms are one of the riskiest possible businesses," said Dr. Rebecca Fielding-Miller, an epidemiologist who teaches at UC San Diego, in an email to ABC 10News. "By definition, people are breathing heavily in an indoor space, which is a recipe for spread. And while I haven’t been inside a gym since March, I would hazard a guess that gyms that are threatening to defy county orders are also not gyms that are enforcing masking policies. They should absolutely be closed."During the last COVID-19 surge in August, Ramona Fitness Centers became one of the first and only businesses cited and then charged by the District Attorney for remaining open in violation of public health orders. San Nicolas says he expects the County to come after him again. He is represented by a legal team attempting to sue for businesses to stay open. 2059
