Three national parks recorded its highest number of visitors last month.According to The Billings Gazette, Yellowstone National Park recorded more than 360,000 visitors in October, which is an increase of 110% from last October.Its previous October record was set in 2015 when 252,000 guests visited the 2.2 million-acre national park.But for the whole year, visitation is down 6% from the same time as last year, with about 3,740,000 people visiting the park, the Associated Press reported, but that's because the park was closed for two months due to the coronavirus pandemic.Another national park that saw record crowds was Grand Teton National Park, located 31 miles from Yellowstone.In October, Grand Teton saw more than 351,000 guests, which is up 88% percent from this exact time last year, the Gazette reported. According to the newspaper, the national park's previous October record was set in 2018 with more than 207,000 visitors.The newspaper also stated that Glacier National Park recorded more than 125,000 tourists last month. In 2018, only 78,000 guests visited, and over the previous three years, the national park has recorded about 85,000 people. 1172

Too few new antibiotics are under development to combat the threat of multidrug-resistant infections, according to a new World Health Organization report published Tuesday. Adding to the concern: It is likely that the speed of increasing resistance will outpace the slow drug development process.As of May, a total of 51 antibiotics and 11 biologicals -- medical products often made from natural sources -- are being developed, the new report said."The idea is that biologicals could replace use of antibiotics, which could help in overcoming the resistance problem," Peter Beyer, an author of the report and senior adviser to the WHO's Department of Essential Medicines and Health Products, wrote in an email.Seemingly, this large number of potential new drugs should suffice, yet it is not nearly enough.First, just 33 of the antibiotics in the pipeline target priority pathogens. This year, the WHO published a list of a dozen "priority pathogens": 12 separate families of antibiotic-resistant bacteria that pose the greatest threat to human health.Among the priority pathogens is a drug-resistant tuberculosis, which kills about 250,000 people around the world each year, and a variety of multidrug resistant strains -- Acinetobacter, Pseudomonas and various Enterobacteriaceae -- which are responsible for infections in hospitals and nursing homes and among patients whose care requires ventilators and catheters.Of the 33 potential medicines for treating priority bug infections, only eight are innovative treatments. The other 25 are simple modifications of existing families of antibiotics. At best, then, the 25 will serve as short-term solutions since it is expected bacteria will quickly adapt to and resist these new (though somewhat familiar) drugs, according to the WHO."It is difficult to speculate why companies develop specific new medicines," Beyer noted. "But in general many new treatments do not necessarily constitute advances over existing treatments."TB infections require a combination of at least three antibiotics, according to the new report, yet only seven of the new TB medicines are even in clinical trials. Soon, there will be a serious lack of treatment options for this infection, the report warns.The same is true for gram-negative pathogens, which can cause severe, often deadly infections typically in hospitals and nursing homes.Gram-negative bacteria have more complex cell walls than gram-positive, explained Beyer. "In a nutshell, it is more complex to develop a novel antibiotic that can penetrate the complex gram-negative cell wall and stay inside the bacterium," he wrote.Finally, the WHO sees too few oral antibiotics being developed. These are necessary "to target the critical priority pathogens (and) be accessible in low- and middle-income countries," Beyer noted.To address the problem of developing new antibiotics, the WHO and the Drugs for Neglected Diseases Initiative set up the Global Antibiotic Research and Development Partnership. However, new drugs alone cannot combat the threat of antimicrobial resistance. The WHO is also working to improve infection prevention and control while developing guidance for the responsible use of antibiotics."Always seek medical advice before taking antibiotics and then always follow the advice of the health-care professional," Beyer noted.The new report is a "fantastic (and very useful!) summary" of the antibiotic situation, wrote Bill Hanage, an associate professor of epidemiology at Harvard T.H. Chan School of Public Health, in an email. Hanage, who has also published studies of antibiotic resistance, was not involved in the new report.Although the risk of getting a completely resistant infection is low in the United States, about 2 million people each year become infected with "resistant enough" bacteria that are harder to treat, Hanage said. And every year, more than 20,000 people die of these infections."More resistant infections don't just mean you or someone you care about is more likely to die from one, they also mean healthcare will get even more expensive," Hanage said. "Many of the procedures we take for granted in medicine, from cancer treatments to surgeries, depend on our ability to handle infections that happen in the course of treatment."The number of new drugs in development is simply not enough, he said."The great majority will not make it into the hands of doctors or your treatment," Hanage wrote. "As the report states, for drugs to be used in humans they have to pass 3 hurdles, the phase 1, 2 and 3 trials. Drugs entering that pipeline have just a 14% chance of getting all the way through to be used in humans." 4676

There was a heavy police presence Monday morning at Olympic Heights High School in West Boca Raton, Florida as students walked out of class to protest gun violence after last week's shooting in Broward County.FULL COVERAGE: Parkland school shootingStudents walked out of class at about 9:30 a.m. and held signs saying "No More Silence, End Gun Violence" and shouted "we want change."The protest comes after the mass shooting last week killed 17 people at Marjory Stoneman Douglas High School in Parkland.NOW: Studenys at @OHPride_of_Boca walking out of class, standing up to #GunViolence @wptv @FOX29WFLX pic.twitter.com/wOHVoRVAhn— Andrew Ruiz (@AndrewRuizWPTV) February 19, 2018 703

Thursday's NBA Playoff showdown between the Golden State Warriors and Houston Rockets was a pivotal game, one that could decide who advances to the NBA Finals. But the NBA Finals and basketball were not on people's minds for a few brief minutes before tip-off. Instead, last week's mass shooting at Santa Fe High School in Texas dominated the thoughts of those in attendance as the Rockets welcomed survivors from last week's mass shooting, which killed eight students and two teachers. Graduates from Santa Fe High School, along with the town's first responders, were in attendance and honored in a pregame ceremony. There was also a moment of silence in memory of the 10 people who lost their lives.  735

There are thousands of suitcases in Ocean City over the summer, but police found one packed with something unusual on Tuesday. According to Lt. Schreier of the Worcester County Sherriff’s office, a couple stumbled over a trunk in the water in West Ocean City at Homer Gudelsky Park. Inside they found personal objects like shoes and pottery as well as one or two bones. Maryland State Police, Maryland Natural Resources Police and the Worcester County Sheriff's Office are on the beach investigating, and a dive team was trying to pull the trunk from the water in hopes of reserving anything that could be evidence.  664
