New spikes in COVID-19 cases have reinforced the importance of basic disinfecting and cleaning our homes to stop the novel coronavirus spread.But how do we know that the cleaners we have are effective in killing COVID-19 and other viruses?"One of the things that's important to know: Is there is a lot of good evidence that the coronavirus is one of the easiest types to kill?" said Texas A&M University - Corpus Christi Associate Professor of Chemistry Dr. Patrick Larkin.Yes, he said. He believes most household cleaners will destroy the virus.He said the best chemicals to use for disinfecting are, bleach, ammonia, and alcohol. However, he does warn that precautions be taken with alcohol concentrations."For example with isopropyl alcohol, you need at least a 50 percent solution; and ethanol [or ethyl] alcohol, you want at least 60 percent," he said.But, take note -- there also are guidelines for how you should clean, so it can be the most effective."CDC guidelines say you should clean the surface with soap and water first, and then apply your sanitizing or disinfectant solution," said retired Certified Industrial Hygienist Tom Samson. "Leave it on for at least one minute, and then you can rinse it off."Samson said not all household cleaners are the same, and do not have the same contact-surface time that is required. He recommends reading the labels of the cleaner you intend to use.Larkin and Samson said it is easy to make your own cleaners at home. However, be cautious about mixing chemicals, and be aware what you are cleaning with."The chemistry of mixing a chlorine-based cleaner with an ammonia-based cleaner can be deadly to those in the immediate area," said Samson. "The reaction of these two cleaners is to release chlorine products into the surrounding environment, in some cases, enough to cause severe injury or death. People need to know to get out of the area if this reaction happens and take their kids and pets with them!"Samson notes the Environmental Protection Agency also has a list of cleaners that will kill the novel coronavirus.This story originally reported by Chelsea Torres on kristv.com. 2149

New York City is painting the town…white! But the paint isn’t for aesthetics. The city is coating rooftops in order to reduce the internal temperature of a building by 30 percent."Painting a rooftop reflects the sun's radiant energy on the building,” explains Gregg Bishop, commissioner with NYC Small Business Services.Bishop says this reduces air conditioning costs.The initiative is called Cool Roofs. Officials say the initiative is helping to reduce the impact New York has on the climate, while lowering energy costs."Here in the city, we're facing temperatures that can be up to 22 degrees hotter than surrounding rural and suburban areas," says Jainey Bavishi, with the Mayor’s Office of Recovery and Resiliency.Since the program launched, they've covered 9 million square feet of rooftops.A similar initiative launched recently in Los Angeles, where they're testing reflective streets. The trend is growing. Academic research shows reflective surfaces do make a difference."What some of my own work has found out is that cool roofs are actually very effective at decreasing, for example, summertime temperatures, on the order of 1 to 3 degrees which is quite significant," explains Dr. Matei Georgescu, with the Global Institute of Sustainability at Arizona State University.While there are definitely benefits to making surfaces like this rooftop reflective, researchers say there may be some downsides as well."If you deploy highly reflective roofs, you're now assuming high reflectivity during the entire winter,” says Dr. Georgescu. “In other words, you're making things a lot colder than normally they would have been.”Dr. Georgescu studies reflective surfaces and says it could mean higher heating costs in the winter."We don't wanna give back 50 percent of these benefits during the winter."He says a possible solution might be reflective covers that would be removable during cold months.The city says any higher heating bills in the winter have been negligible. For now, officials have no plans to cool down the Cool Roofs program. 2067

NEW YORK -- A bodega clerk who was attacked by a customer in New York City is concerned mask laws will get someone killed, he said Sunday.Javier Franco and Aneuri Castillo were in a Morrisania bodega several weeks ago when they were attacked. Franco was stacking the shelves when he asked a customer to put on a mask. The customer punched him in the face.“The mask law is going to get someone killed," Franco said. "We are doing our best trying to obey the law so we don’t lose our liquor license, but it seems we could lose our life instead."Castillo was smacked in a mask confrontation with a customer."This was shocking to me," he said. "I tried to do what the governor asked us. I told him it was the law. I’m scared! Maybe he’ll come back and shoot me. It’s so hard coming to work not knowing how the day will go. I have a family and they need me, I don’t want to die in the bodega."United Bodegas of America spokesman Fernando Mateo said both incidents happened within minutes of one another. He said they're meeting with NYPD Commissioner Dermot Shea soon to address their concerns.“The mayor and the governor have a responsibility to keep us all safe," he said. "We invested in NYC and they must ensure our public safety."This story was originally published by Aliza Chasan at WPIX. 1298

NEW YORK CITY — Not all New York City public schools will begin their in-person instruction Monday as originally planned, Mayor Bill de Blasio announced Thursday."For months, teachers, principals and school staff have been working hard to make sure our students have the education they deserve while putting health and safety first," de Blasio said.The announcement came as educators have raised concerns over safety measures in school buildings and lack of preparedness.The mayor said he has talked with school officials about different types of school buildings and their levels of readiness and decided to develop an updated approach with several phases for resuming in-person learning.Beginning Monday,3-K, Pre-K and District 75 schools will reopenSept. 29: K-5 and K-8 schools will openOct. 1: Middle and high schools will reopenAll students in full remote programs will continue as planned, starting full-day instruction on Sept. 21."Our students, staff, and families have demonstrated tremendous resilience over the last six months, and we're going to continue to build on all the work we've done as we move forward," Schools Chancellor Richard Carranza said. "We are giving our schools more staff, more time, and more support to have the strongest possible start to the most unprecedented school year."The mayor also announced another 2,500 educators will be deployed to New York City schools in addition the 2,000 added earlier this week. The 4,500 total is still short of the 10,000 more staff requested by city schools.Those educators are expected to assist in in-person learning in schools to make sure that all students have a rigorous learning experience in a safe, healthy environment. President of the Council of School Supervisors and Administrators Mark Cannizzaro said the additional teachers would fulfill staffing needs at 3-K, Pre-K, District 75, K-5 and K-8 schools.The Department of Education continues to work with middle and high schools to establish their needs for additional staffing, de Blasio said.When asked what was "the straw that broke the camel's back," de Blasio, Cannizzaro and United Federation of Teachers Pres. Michael Mulgrew said school staffing shortages had not been resolved enough to have all school buildings safely reopen.Mulgrew also said it became apparent a "snow day scenario," where a large amount of students would be placed into a room with a teacher, cannot be used during the pandemic.He also acknowledged staffing issues have been raised for weeks, and they have been addressing the concerns and monitoring, but as teachers returned to schools, "that was when we noticed the huge need for more educators." 2672

NEW YORK (AP) — Apple has dropped the hugely popular "Fortnite" game from its App Store after the game's developer introduced a direct payment plan that bypasses Apple's platform. Apple takes a 30% cut from in-app revenue purchases, which has long been a sore spot with developers. "Fortnite" is free, but users can pay for in-game accouterments like weapons and skins. The game's developer, Epic Games, said in a blog post it was introducing Epic Direct payments, a direct-payment plan for Apple's iOS and Google Play that bypasses the App Store. Apple said the service violated its guidelines.“Epic enabled a feature in its app which was not reviewed or approved by Apple, and they did so with the express intent of violating the App Store guidelines regarding in-app payments that apply to every developer who sells digital goods or services,” Apple said in a statement to Bloomberg News' Mark Gurman. 912
