"You might want to step back," said Darryl Clinton as yet another explosion boomed nearby.He seemed to know exactly what that sound meant. A fissure that violently cracked open the earth's surface was spewing more lava and, possibly, more lava bombs -- flying chunks of molten rock.Clinton spoke to CNN on Friday, while defending two homes in Pahoa roughly 100 yards from the unstable fissure that's been erupting for more than a week now.Even to get from one house to another takes a life-or-death game of frogger.Clinton pointed to the remains of one lava bomb purged from a nearby fissure that landed just inches from a friend's house. The yard was littered every few feet with with fallen lava, but Clinton wasn't worried about getting hit by the hunks of molten rock."It's almost like catching a football," Clinton said in describing how to avoid being hit. "But you don't want to catch this football."Armed with just a fire extinguisher and a garden hose, Clinton has been defending the homes that belong to friends.He's been spraying down the burning lava bombs that hit the houses to prevent them from catching fire. Heaps of flaming rock have already shattered windows and destroyed a septic tank -- setting it ablaze with a blue flame of burning methane gas.A day later, Clinton fell victim himself -- distracted by his cell phone for mere moments, when a bowling ball-sized lava bomb hit him in the leg while he was standing on the porch.His friend and ex-wife Lisa Roach was nearby and able to take him to the hospital. She had been helping him defend the homes -- the pair were keeping watch in shifts.Roach told CNN she believes the intense heat of the lava bomb actually cauterized the wound, preventing it from bleeding more than it did.The burning projectile also set Clinton's porch ablaze, but a neighbor managed to extinguish it. Clinton is currently in the hospital, recovering. Roach said he can already wiggle his toes, but won't be able to put weight on his injured foot for at least six weeks.He's had two surgeries already, and will likely have more, but is expected to recover. 2112

 Former Director of National Intelligence James Clapper said Sunday that President Donald Trump's downplaying the threat posed by Russia's meddling in last year's election was dangerous to US national security.Speaking on CNN's "State of the Union" alongside former CIA Director John Brennan, Clapper said: "The threat posed by Russia, as John just said, is manifest and obvious. To try to paint it in any other way is, I think, astounding, and in fact, poses a peril to this country."Clapper, a CNN analyst, was responding to Trump's mixed comments about alleged Russian interference in the 2016 election. 619

(AP) — Researchers are concerned about reports from Britain and South Africa of new coronavirus strains that seem to spread more easily. Scientists say it's unclear if that's true. And for now, they don't think the new strains cause more severe COVID-19 illness or pose any concern for vaccines. Viruses naturally evolve as they move through the population. One strain recently detected in England has a lot of changes to the spiky protein that's targeted by current vaccines. The advice to the public remains the same — wear a mask, wash hands often, and keep social distance to avoid catching and spreading the virus. 627

With news of charges against New England Patriots owner Robert Kraft in a human-trafficking and prostitution sting, a question arises: what are potential ramifications?Owners are subject to the NFL’s personal conduct policy. Owners and league employees are held to an equally stringent or higher standard than the players. The NFL is capable of handing down consequences to employees that are more significant than a court of law. According to 458

(AP) — The first report cards of the new school year are arriving with a lot more Fs than usual, and it’s not just parents who are getting distressed. School districts from coast to coast have reported the number of students failing classes has risen by as many as two or three times — a sign of the struggles many students are having with distance learning. English language learners, those with disabilities, and other disadvantaged students have been at particular risk.Educators see a number of factors at play: Students learning from home skip assignments — or school altogether. RELATED: Rise in 'F' grades at some North County schools spark virtual learning concernsInternet access is limited or inconsistent, making it difficult to complete and upload assignments.In response schools have been ramping up outreach efforts, prioritizing the return of struggling students for in-person learning and in some cases changing grading policies and giving students more time to complete assignments. 1007
