Getting into an Ivy League or top ten university is typically extremely competitive and difficult, but the effects of the pandemic may be making it easier for some to now get into their dream school.Part of the reason for this is that enrollment is down at college campuses across the country.One poll, conducted by College Reaction and Axios, shows roughly 22 percent of college students have decided to take a gap year. That equates to about 4 million fewer college students enrolled this academic year.“Right now, colleges, as you have seen, they are desperate for tuition dollars,” said Christopher Rim, CEO of Command Education, a company that helps students get into competitive colleges. "Six out of 10 colleges want to fill their classes.”For months now, Rim has seen how the pandemic is making it much easier for students to get into some highly-competitive schools.“We had students who were waitlisted at top 10 and top 15 universities, and in a typical year, they would not have been getting in,” said Rim. “In June or July, they were getting offers of admissions, saying they are off the waitlist.”Rim says it’s because students have been deferring enrollment or taking a gap year.The gap-year trend and resulting reduced competition is also leading to a trend in college transfers. Rim’s company has had three to four times as many college students contact them this year, looking for help with a transfer.“We are having all of these transfer students reach out to us and say, ‘You know what? I want to transfer. This is the time to transfer. I’ll have the best shot. If my dream school was Georgetown or if my dream school was Yale, what do I need to do to stand out and get in because these schools also need students?’” said Rim.While current transfer students may have less competition, and thus, a better shot at getting into their preferred schools, high school seniors should prepare for this trend to reverse when they are applying for admissions in the fall of 2021.“For the current students right now, who are applying to colleges and they are seniors in high school, they are going to have the most difficult time,” said Rim. “Because all the students who took the gap year have taken those spots. Harvard has said 20 percent of their freshman incoming class has opted to take a gap year, which means Harvard is going to take 20 percent fewer freshmen.” 2385

Hot weather can increase the risk of natural disasters like droughts and wildfires, now, there is evidence extreme heat can increase harmful chemicals in the air.A study published recently in Science Advances looked at asphalt under different temperature conditions.“A main finding is that asphalt-related products emit substantial and diverse mixtures of organic compounds into the air, with a strong dependence on temperature and other environmental conditions,” says Peeyush Khare, a Yale chemical and environmental engineer and the lead author of the study, in a statement.The researchers took real-world samples of fresh road asphalt and put them in a controlled furnace with purified air. They heated the samples to temperatures between 104 and 392 degrees Fahrenheit, and measured the chemical components in the air.Total emissions nearly doubled when temperatures went from 104 to 140 degrees. At 104 degrees, 94 percent of the emissions measured were hydrocarbons.The group also exposed the asphalt samples to replicated solar heat, including UVA and UVB wavelengths, and found the rate of emission of potentially harmful chemicals increased. Showing that not only heat, but also solar radiation contributed to asphalt producing air pollution.Paved surfaces and roofs make up approximately 45% and 20% of surfaces in U.S. cities, respectively.Asphalt can be quite a bit hotter than the air around it, getting about 40 to 60 degrees warmer than the recorded air temperature.The researchers concluded that while policies and regulations have been put in place about car emissions and other forms of air pollution, asphalt should not be overlooked as a contributor.“It's another important non-combustion source of emissions that contributes to SOA (secondary organic aerosol) production, among a class of sources that scientists in the field are actively working to constrain better,” Drew Gentner, associate professor of chemical & environmental engineering, said. 1983

GUERNEVILLE, Calif. (AP) — Two communities in Northern California's wine country were accessible only by boat Wednesday after a rain-swollen river overflowed its banks following a relentless downpour across an already waterlogged region.The small city of Guerneville north of San Francisco "is officially an island," with the overflowing Russian River forecast to hit its highest level in about 25 years, the Sonoma County Sheriff's Office said in a statement."Nobody is coming or going from the Guerneville area at this time," said sheriff's Sgt. Spencer Crum. The nearby town of Monte Rio was also isolated by floodwaters and all roads leading to it were swamped.The still rising Russian River was engorged by days of rain from western U.S. storms that have also dumped heavy snow in the Sierra Nevada, throughout the Pacific Northwest and into Montana, where Gov. Steve Bullock signed an emergency order to help keep up the supply of heating fuel amid frigid temperatures.Snow from the storms closed roads and schools and toppled trucks and trees from Oregon to Montana and an avalanche in the Sierra prompted Amtrak to suspend rail service between Sacramento and Reno, Nevada.The Russian River topped 42 feet (13 meters) Wednesday afternoon, when television helicopter footage showed homes underwater and cars submerged. It could crest at more than 46 feet (14 meters) by Wednesday night, officials said. About 4,000 residents in two dozen river communities were ordered to evacuate Tuesday evening but officials estimate only about half heeded the orders, Crum said.Jeff Bridges, co-owner of the R3 Hotel in Guerneville, said he and others who stayed behind were well prepared to ride out the storm. He and employees spent most of the night moving computers, business records and furniture to second-floor room. Reached by telephone, Bridges said there was about 7 feet (2 meters) of water at his two-story home in Guerneville Wednesday but was not worried."As long as everybody is safe, dry and warm, it's all fine. You just ride it out," said Bridges, noting that this flood was the fourth he's experienced in 33 years.He added: "People in Florida have hurricanes, people in Maine have blizzards; we have floods," he said. "It's the price we have to pay to live in paradise."Several areas in California set record-high rainfall totals, including nearby Santa Rosa, which had nearly 8 inches (20 centimeters) of rain in one day. The often-waterlogged Venado weather station 5 miles (8 kilometers) from Guerneville recorded more than 20 inches (50 centimeters) of rain in 48 hours.In the Sierra Nevada, which has already seen a month of heavy snow, two Amtrak trains together carrying nearly 300 passengers stopped and reversed directions because of an avalanche that closed railroad tracks. Service on Amtrak's California Zephyr between Reno and Sacramento, California, has been suspended until weather conditions improve, Amtrak spokeswoman Kimberly Woods said.California officials were also concerned about potential mudslides in saturated wine country hillsides and in areas scarred by wildfires in 2017.A mudslide Tuesday near Monte Rio trapped a man and a woman before they were rescued, messy but unharmed."I fell into the mud when the tree fell over the top of me. It happened so fast you don't even know," Kear Koch told KGO-TV.Elsewhere in the area, several people had to be rescued from cars stranded while motorists tried to drive through flooded roads. Nina Sheehan, who is visiting from North Carolina, had to abandon her rental SUV after it got stuck in a flooded hotel parking lot."We made a decision to take the rental car through the waist-high water and we got two thirds of the way and then the car stalled," she said. "Do not try to go through any water over a foot high because you never know what you're going to find."Firefighters in Monte Rio worked through the night pulling people out of cars stuck in flooded roadways and getting people out of their homes as water approached, Fire Chief Steve Baxman told the Press-Democrat newspaper of Santa Rosa."We took 17 people out of cars and houses during the night. Too many people are driving into water," he said.Other waterways, including the Napa River, also were expected to overflow their banks as an ocean-spanning plume of moisture continued tracking through the West.___Rodriguez reported from San Francisco. 4401

HAMPTON, N.H. (AP) — Joe Biden said he would be open to breaking up Facebook, a sign of the deep skepticism among many Democratic presidential contenders about the power of massive technology firms.In an interview on Monday with The Associated Press, the former vice president said that dismantling large technology companies is "something we should take a really hard look at."Sen. Elizabeth Warren of Massachusetts has been the most outspoken Democratic presidential candidate to press for greater regulation of Silicon Valley's most prominent companies. While Biden didn't fully embrace her proposal — saying it's "premature" to make a final judgment — he praised Warren and said she "has a very strong case to be made" for cracking down on tech giants.The comments demonstrate how Facebook is increasingly a flashpoint in the campaign for the Democratic presidential nomination, with some candidates arguing the influence of such companies is unchecked, allowing misinformation to poison the public debate. Sen. Kamala Harris of California said this weekend that she was open to revamping Facebook, telling CNN the company is essentially a public utility. But Sen. Cory Booker of New Jersey told ABC that such calls aren't very different from the tough tactics President Donald Trump takes against his enemies.Regardless of whether Facebook is ultimately broken up, Biden told the AP that the Trump administration hasn't done enough to enforce antitrust laws in a variety of industries. 1498
