There are 88 national park forests in the US you could choose from that would allow you to cut your own Christmas tree.And all you need is a Christmas tree cutting permit.According to the U.S. Forest Service, visitors need a Forest Service-issued permit, which is available for purchase on the Recreation.gov website or at local offices.According to a press release, the Forest Service began selling permits in a "modernize" way on Oct. 15, as a way to minimize in-person interaction during the coronavirus pandemic.The program, the agency said, is also good for the forest."The Christmas tree permit program is also a tool used in thinning dense, unhealthy stands of trees," the agency stated in an October press release. "Forest health experts help identify areas where Christmas trees can be cut, opening up forage for wildlife and allowing the remaining trees to grow larger."According to the Forest Service, there are specific guidelines to follow, including having your permit on you at all times. You'll also need to contact the forest district office nearest you for cutting instructions.The permits will set you back between to , varying by location. 1173

TIJUANA, Mexico (AP) — Migrants approaching the U.S. border from Mexico were enveloped with tear gas Sunday after a few tried to breach the fence separating the two countries.U.S. agents shot the gas, according to an Associated Press reporter on the scene. Children were screaming and coughing in the mayhem.Honduran migrant Ana Zuniga, 23, said she saw migrants open a small hole in concertina wire at a gap on the Mexican side of a levee, at which point U.S. agents fired tear gas at them."We ran, but when you run the gas asphyxiates you more," she told the AP while cradling her 3-year-old daughter Valery in her arms.RELATED: Caravan marches toward US border in show of forceMexico's Milenio TV also showed images of several migrants at the border trying to jump over the fence. Yards away on the U.S. side, shoppers streamed in and out of an outlet mall.U.S. Border Patrol helicopters flew overhead, while U.S. agents held vigil on foot beyond the wire fence in California. The Border Patrol office in San Diego said via Twitter that pedestrian crossings have been suspended at the San Ysidro port of entry at both the East and West facilities. All northbound and southbound traffic was halted.Earlier Sunday, several hundred Central American migrants pushed past a blockade of Mexican police who were standing guard near the international border crossing to pressure the U.S to hear their asylum claims. They appeared to easily pass through without using violence, and some of the migrants called on each other to remain peaceful.RELATED: Woman with child injured while scaling border fenceThe migrants carried hand-painted American and Honduran flags and chanted: "We are not criminals! We are international workers!"A second line of Mexican police carrying plastic riot shields stood guard outside a Mexican customs and immigration plaza.That line of police had installed tall steel panels behind them outside the Chaparral crossing on the Mexican side of the border.Migrants were asked by police to turn back toward Mexico.More than 5,000 migrants have been camped in and around a sports complex in Tijuana after making their way through Mexico in recent weeks via caravan. Many hope to apply for asylum in the U.S., but agents at the San Ysidro entry point are processing fewer than 100 asylum petitions a day.Irineo Mujica, who has accompanied the migrants for weeks as part of the aid group Pueblo Sin Fronteras, said the aim of Sunday's march toward the U.S. border was to make the migrants' plight more visible to the governments of Mexico and the U.S."We can't have all these people here," Mujica told The Associated Press.Tijuana Mayor Juan Manuel Gastelum on Friday declared a humanitarian crisis in his border city of 1.6 million, which he says is struggling to accommodate the crush of migrants.U.S. President Donald Trump took to Twitter Sunday to express his displeasure with the caravans in Mexico."Would be very SMART if Mexico would stop the Caravans long before they get to our Southern Border, or if originating countries would not let them form (it is a way they get certain people out of their country and dump in U.S. No longer)," he wrote.Mexico's Interior Ministry said Sunday the country has sent 11,000 Central Americans back to their countries of origin since Oct. 19. It said that 1,906 of them were members of the recent caravans.Mexico is on track to send a total of around 100,000 Central Americans back home by the end of this year.RELATED: 3488

Top North Korean officials warned the United States in a letter that denuclearization talks are "again at stake and may fall apart," sources familiar with the process told CNN.The letter was delivered to US Secretary of State Mike Pompeo, who abruptly canceled his fourth trip to Pyongyang, hours before he was scheduled to depart with his new special envoy Stephen Biegun on Friday, sources said.Three sources with direct knowledge of the North Korean position on denuclearization said the letter stated that Kim's regime felt that the process couldn't move forward because "the US is still not ready to meet (North Korean) expectations in terms of taking a step forward to sign a peace treaty."The US has so far been unwilling to replace the armistice agreement that ended the Korean War with a permanent, legally binding peace treaty, which would require the approval of two-thirds of the US Senate.If a compromise cannot be reached and nascent talks crumble, Pyongyang could resume "nuclear and missile activities," the sources said.The existence of the letter, sent to Pompeo by Kim Yong Chol, the former head of North Korea's spy agency, was first reported by the Washington Post.The Post, which characterized the letter as a "secret" communication, said it wasn't clear how Kim had gotten the letter to Pompeo, but suggested that it may have been sent through its UN mission.However, Pompeo has been relying on other backchannels, as opposed to dealing directly with his diplomatic counterpart North Korean Foreign Minister Ri Yong Ho, one source said."Before and after Pompeo became the Secretary of State, he seemed to be more interested in maintaining and engaging with Kim Yong Chol through a backdoor channel, rather than with his formal counterpart Ri Yong Ho," said the source. 1809

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

TIJUANA, Mexico (KGTV) - The first group of people from the migrant caravan have arrived in Tijuana, according to a Mexican journalist. According to journalist Jorge Nieto, the group has 85 people. This group is reportedly people of the LGBTQ+ community and they left the others behind because they felt they were being discriminated against. They arrived at the Tijuana bus station, then took buses to an Airbnb in Playas de Tijuana, paid for by U.S. lawyers with the caravan.RELATED: Bulk of migrant caravan is 1,600 miles away from TijuanaOnce at the house, neighbors clashed with the migrants, "Yelling at them go away go to a shelter, this is not your place, all you came here this is a safe area and we are afraid of you," Nieto said shelters aren't an option as they are already over capacity from the last caravan.Nieto said the migrants defended themselves, saying the neighbors could hurt them as well, "we're not going to make noise, we're not going to make any mess."One migrant spoke with reporters saying they had the right to seek refuge in another country and pursue a better life with respect.It's not clear when they plan to turn themselves into U.S. Customs and Border Protection (CBP) and seek asylum in the United States.The group will reportedly spend a few days in Tijuana to rest. RELATED: Interactive Map: Migrant caravan journeys to U.S.-Mexico border / Timeline: Migrant caravan travels to border / Photos: Migrant caravan makes its way to border 1531
