The Trump Administration wants to change the definition of a showerhead to let more water flow, addressing a pet peeve of the president who complains he isn’t getting wet enough.Publicly talking about the need to keep his hair “perfect,” President Donald Trump has made increasing water flow and dialing back long held appliance conservation standards — from light bulbs to toilets to dishwashers — a personal issue.But consumer and conservation groups said the Department of Energy’s proposed loosening of a 28-year-old energy law that includes appliance standards is silly, unnecessary and wasteful, especially as the West bakes through a historic two-decade-long megadrought.Since 1992, federal law has dictated that new showerheads shouldn’t pour more than 2.5 gallons of water per minute (9.5 liters). As newer shower fixtures came out with multiple nozzles, the Obama administration defined the showerhead restrictions to apply to what comes out in total. So if there are four nozzles, no more than 2.5 gallons total should come out between all four.The new proposal Wednesday would allow each nozzle to spray as much as 2.5 gallons, not just the overall showerhead.With four or five or more nozzles, “you could have 10, 15 gallons per minute powering out of the showerhead, literally probably washing you out of the bathroom,” said Andrew deLaski, executive director of the energy conservation group Appliance Standards Awareness Project.On the White House South Lawn in July, Trump made the issue personal:“So showerheads — you take a shower, the water doesn’t come out. You want to wash your hands, the water doesn’t come out. So what do you do? You just stand there longer or you take a shower longer? Because my hair — I don’t know about you, but it has to be perfect. Perfect.”DeLaski and officials at Consumer Reports said there’s been no public outcry or need for change. The Department of Energy’s own database of 12,499 showerheads showed 74% of them use two gallons or less water per minute, which is 20% less than the federal standard.“Frankly it’s silly,” deLaski said. “The country faces serious problems. We’ve got a pandemic, serious long-term drought throughout much of the West. We’ve got global climate change. Showerheads aren’t one of our problems.”Energy Department spokeswoman Shaylyn Hynes said the 2013 Obama definition of showerhead clashes with what Congress intended and the standards of the American Society of Mechanical Engineers.If the rule is adopted, Hynes said it would be “allowing Americans — not Washington bureaucrats — to choose what kind of showerheads they have in their homes.”Officials at the industry group Plumbing Manufacturers International did not respond to a request for comment.Appliance and plumbing energy and water conservation standards save consumers about 0 a year on energy bills, deLaski said.If people are having trouble getting water flowing in their shower, they should check their home’s water pressure and can replace a faulty showerhead for not much money, deLaski said.A 2016 test of showerheads by Consumer Reports found that the best rated showerheads — including a model — provided a pleasing amount of water flow and met federal standards, according to David Friedman, a Consumer Reports vice president and former acting assistant energy secretary.DeLaski said he has had a hard time understanding the president’s shower concerns.“If the president needs help finding a good shower, we can point him to some great consumer websites that help you identify a good showerhead that provides a dense soak and a good shower,” deLaski said. 3624

The Senate on Wednesday will hold a hearing regarding the safety of vaccines, which will feature appearances by Surgeon General Dr. Jerome Adams and National Institutes of Health Director Dr. Francis Collins.The hearing, hosted by the Senate HELP Committee, will discuss the role of vaccines in preventing infectious disease outbreaks and protecting public health.Wednesday's hearing will also include information on a potential COVID-19 vaccine.Top U.S. health experts like Dr. Anthony Fauci say they are cautiously optimistic that there will be enough evidence to grant Emergency Use Authorization to top vaccine candidates by the end of 2020. However, recent polls indicate that some Americans remain skeptical about vaccines.A recent CBS News poll indicates that just 21% of American voters would receive a COVID-19 if one were made available at no cost. That's down from about 30% earlier this year. Two-thirds of those polled say they feel a vaccine would be "rushed" if a vaccine were made available this year.Fauci has said that if a potential vaccine is 75% effective against the virus, it still may not be effective in promoting inoculation levels necessary for "herd immunity" in the U.S. due to Americans' ongoing skepticism about vaccines.Nine vaccine makers banded together to sign a pledge on Tuesday to say that they will not seek Emergency Use Authorization for their vaccine candidates until scientific methods prove they are safe for widespread use. 1476

The Trump administration issued an order on Friday that will attempt to ban Americans from downloading Chinese-owned social media apps TikTok and WeChat beginning Sunday.The order issued by Commerce Department Sec. Wilbur Ross, requires companies like Apple and Google to remove the apps from their online stores by Sunday. It also orders that all U.S. companies cease working with WeChat to transfer funds or process payments in the app.It's currently unclear if Apple and Google will choose to comply with the Commerce Department's order or if they will choose to file a lawsuit to keep the apps in their stores.“Today’s actions prove once again that President Trump will do everything in his power to guarantee our national security and protect Americans from the threats of the Chinese Communist Party," Ross said in a statement. “At the President’s direction, we have taken significant action to combat China’s malicious collection of American citizens’ personal data, while promoting our national values, democratic rules-based norms, and aggressive enforcement of U.S. laws and regulations.”There will be no penalty for those who have already downloaded the app and continue to use it to communicate. However, the order says that messaging on the apps "could be directly or indirectly impaired” by the order.In the case of TikTok, the order stipulates that its parent company, ByteDance, has until Nov. 12 to "resolve" its national security concerns. ByteDance has been in talks to sell its American business with U.S. software company Oracle.Privacy experts have raised concerns about both Chinese-owned apps, saying Americans' personal information could fall into the hands of the Chinese government. In August, Trump signed an order that set a Sept. 20 deadline for the sale of TikTok's U.S. business."Each collects vast swaths of data from users, including network activity, location data, and browsing and search histories," the Commerce Department's order reads. "Each is an active participant in China’s civil-military fusion and is subject to mandatory cooperation with the intelligence services of the CCP. This combination results in the use of WeChat and TikTok creating unacceptable risks to our national security." 2242

The world’s population has been growing, spiking in the last few centuries, and now sits around 7.6 billion. A study published this week suggests global population will peak around the year 2064 at roughly 9.73 billion people.Researchers looking at the models believe the world’s population will then begin declining, reaching roughly 8.79 billion in the year 2100. Their reasoning for the decline is that “continued trends in female educational attainment and access to contraception will hasten declines in fertility and slow population growth.”According to the study, funded in part by the Bill and Melinda Gates Foundation and published in The Lancet, the five largest countries, population-wise, in 2100 are projected to be India, Nigeria, China, the U.S. and Pakistan. They are projecting America will have a population of roughly 336 million people in 2100. Currently, there are an estimated 331 million people living in the U.S.The average life expectancy in 2100 will be around 80 years old. The current global life expectancy is estimated at 72 years old. 1073
