Researchers are trying to find out as much as they can about great white sharks.After a couple of attacks involving people last year, there are new efforts to learn more about these animals. It’s moments like the incident at Nauset Beach South that shark experts are studying more closely. Video taken of the beach shows white sharks feeding on seals close to the shore. Now, researchers are launching new studies, including one looking at the feeding habits and behaviors of these sharks. “We're essentially going to be giving iPhones to white sharks to track their activity in three dimensions at a really fine scale,” explains Megan Winton, a research scientist with the Atlantic White Shark Conservancy. Winton and other researchers will be tagging sharks with devices similar to what's in smartphones. “We'll be able to identify how often they're feeding on seals. We'll be able to look for relationships with feeding activity and environmental conditions,” Winton says. The data would be given to officials to use to provide better warnings on beaches. The Atlantic White Shark Conservancy is currently pouring over data on a population study they just finished. “Based on the video footage, we were able to identify every shark we saw to an individual level,” Winton says. So far, the researchers have identified more than 300 white sharks. Winton calls it a conservation success story, thanks to protections put in place over the last few decades. “So one thing I like to remind people is that these are large, amazing animals and they're very capable predators and they're certainly deserving of our respect,” Winton says. “But they're not monsters out there, lurking our coastline menacing our beaches. They're big fish out there eating their natural prey item.” White sharks are the only natural predator to seals in the Cape Cod area, which some residents and fisherman see as a nuisance.Researchers want to see how many seals the sharks are eating and if they can impact the seal population. 2023

A growing number of tech companies are making plans for their employees to keep working from home even after the pandemic.It's a move that could have an impact across the country for current employees and job seekers, beyond the typical tech hubs.“The tech sector is over-concentrated in a very short list of places – Seattle, the (San Francisco) Bay area, Boston – in a way that really is harmful to the tech industry but also harmful for the rest of the country,” said Mark Muro with the Metropolitan Policy Program – Brookings Institution. Muro has found that most regional economies in the United States are losing ground in tech and not seeing the kind of growth they've been promised. This comes while big tech hubs are dealing with more traffic and the increased cost of living.Muro says what's happening with tech jobs now amid the pandemic is a win for both the tech hubs and America’s heartland.“A lot of people complain that if they had their druthers, if they could get the same job, they'd move to their hometown or move to name it attractive heartland city,” said Muro. Facebook has said it will let many employees work from home permanently. It also plans to open up remote hiring for some roles and set up new hubs to support remote workers in Atlanta, Dallas and Denver.Twitter also says many of its employees will be allowed to work from home permanently. And Walmart has the same plan for its thousands of tech workers. 1450

A group that raised millions of dollars in a GoFundMe campaign says it has broken ground on a project to build its own stretch of border wall on private property.We Build the Wall, a group founded by a triple amputee Air Force veteran, said in a series of social media posts on Monday that it had started construction on private property in New Mexico. The announcement comes months after the group began its GoFundMe campaign to raise private donations for a border wall, and days after a federal judge blocked President Donald Trump from tapping into billions in Defense Department funds for his administration's wall construction efforts."Buckle up, we're just getting started!" the group wrote in a Facebook post, sharing what it said were images of construction over the weekend.On Monday evening, a CNN team watched as heavy machinery rumbled over the site near the New Mexico-Texas state line near El Paso. Kris Kobach, former Kansas secretary of state and longtime immigration hardliner, spoke to CNN over the clanking and beeping of construction equipment."It's amazing to me how crowdfunding can successfully raise a lot of money, and how many Americans care about this," said Kobach, who's now general counsel for We Build the Wall.A half-mile stretch of wall on the site is nearly finished, Kobach said, costing an estimated million to million to build. The main contractor working at the site: Fisher Industries, a North Dakota-based company that President Trump has been aggressively advocating should be awarded government contracts to build the border wall, 1592
