At a press briefing in Washington on Friday, Vice President Mike Pence said the White House coronavirus task force had identified 16 states — about one-third of all states in the nation — where COVID-19 cases are on the rise.According to Pence, in the other 34 states, there is a "measure of "stability" among cases — saying that while these states may experience new cases, "positivity rates are stable."Pence said that most of the states with rising cases are in the "Sun Belt." He said that he and other health officials would travel to Arizona, Florida and Texas — three states experiencing severe spikes in cases — next week, to meet with governors.The task force reported that a majority of new cases have been reported in people younger than 34 — a development that Pence called "encouraging" in some ways because young people are more likely to recover from the virus.According to Pence, there have been 2.5 million confirmed cases of the virus in the U.S. According to Johns Hopkins, there are about 4,425,000 confirmed cases of the virus.During Friday's briefing, Dr. Anthony Fauci — America's top expert on infectious diseases — said that some areas of the country as facing a "serious problem" amid rising numbers. He added that Americans have a "societal responsibility" to continue social distancing, adding that those who leave their home for crowded places become part of an infectious chain."Ultimately, you will infect someone who is vulnerable," Fauci said.The task force and President Donald Trump held near-daily briefings throughout March and April. But the nation's top health experts have rarely appeared on-camera in recent weeks as the administration has focused on re-starting the economy.The briefing comes a day after Johns Hopkins reported 40,000 new cases of the novel coronavirus, the highest single-day increase since the pandemic began. President Donald Trump has maintained that the increase in cases is the result of increased testing capacity, but the CDC reports hospitalizations linked to the virus are also on the rise.It also comes following a week of confusing messaging regarding the administration's policy on testing. On Saturday at a rally in Oklahoma, Trump told supporters that he asked that testing be "slowed down" to deflate new case numbers artificially. On Monday, press secretary Kayleigh McEnany said Trump made those comments "in jest," but Trump quickly contradicted her, saying he "doesn't kid." Dr. Anthony Fauci, the nation's top infectious disease expert, later testified at a House committee hearing that he had not been told by anyone in the administration to slow down testing, and that increasing testing capacity remains the goal of the task force.Several states that were quick to lift lockdown restrictions are now moving to re-impose social distancing measures. On Friday, Texas ordered the closure of bars and re-imposed limits on in-restaurant dining. Also on Friday, Florida ordered that bars can no longer serve alcohol on-site as cases continue to spike. 3036

Attorneys general from several states plan to jointly file new antitrust litigation against Facebook in the coming days, according to reports from CNBC and the Wall Street Journal.According to CNBC, as many as 40 states are expected to join New York in suing the social media giant. The report also says that the Federal Trade Commission could file a separate but related complaint in district court.While the specifics of the pending lawsuit are unclear, Facebook has been criticized for swallowing up competitors, like Instagram and WhatsApp for fairly reasonable prices.The pending lawsuit would mark the second significant piece of legislation filed against a Silicon Valley giant in recent months. In October, the Justice Department sued Alphabet, the parent company of Google, and alleged the company is a search engine monopoly. 843

As wildfires rage across the western part of the country, firefighters are doing their best to contain the flames and prevent further devastation. Most of the fires are burning in areas that haven't seen a wildfire in a long time, making the loss of life and land even worse."It's been difficult. This is becoming all too common. Another record-breaking, severe, unprecedented fire season here in Colorado. And this was the largest forest fire in the White River National Forest history," said Forest Supervisor Scott Fitzwilliams, speaking about the Grizzley Creek Fire. Fitzwilliams says not all wildfires cause complete destruction. In fact, many provide some crucial ecological benefits. Take the big horn sheep who live in the forest. "Their defense mechanism is those big eyes on the sides of their heads so they can see predators coming. And so, they will abandon a habitat when there's too many trees and too much brush and so in many areas of the canyon, this fire improved big horn sheep habitat," said Fitzwilliams.The Grizzly Creek Fire also burned the top of a canyon, helping the habitat for elk and deer. A silver lining to the Grizzley Creek Fire, which also charred creeks that provide drinking water for an entire town in Colorado and was unexpectedly slowed by an early snowfall in the area.At Sequoia and Kings Canyon National Parks in Central California, fire officials conduct what they call "prescribed burns.""A prescribed burn is literally us giving a prescription to the forest," said Mike Theune, Fire Information Officer for Sequoia and Kings Canyon National Parks. Prescribed burns are slow and steady, clear out unnecessary brush and naturally revitalize a forest, he says.Theune and Fitzwilliams say, for more than 80 years, fire services across the country used to put out any and all fires, even if they occurred naturally, such as from lightning."[In the] early 1900s when forest service came into view and smokey bear and we thought we needed to put out all the fires and we did. And we did a great job of it and Smokey Bear was the best spokesperson we could ever ask for but what that did is significantly change the landscape as far as the density of vegetation," said Fitzwilliams."We need to restore that ecosystem to what those natural levels are and one of the ways we can do it is through a very measured and very managed scientifically based approach to prescribed burning," said Theune.Theune says not all national forests in the country need prescribed burns as there are some states that deal with too many forest fires. National parks and forests officials say it's important to evaluate each individual ecosystem's needs in order to preserve their beauty for years to come. 2730

As we drive down the eerily deserted Hong Kong-Zhuhai-Macau Bridge, the murky waters of the Pearl River Delta stretch as far as the eye can see. There is no land in sight.Spanning 34 miles (55 kilometers), this is the longest sea-crossing bridge ever built. Guo Xinglin, assistant director and senior engineer at the Hong Kong-Zhuhai-Macao Bridge Authority, meets us half way along. As we are buffeted by a strong wind, the tough conditions his construction crew experienced, as they perched on precarious platforms, working miles from land and high over the water, are evident.Guo is visibly proud of his country's monumental achievement. 647
