A worldwide study of the coronavirus released in the journal Cell indicates that the dominant strand of COVID-19 is causing the virus to spread faster.But the study’s authors said that even though the coronavirus is able to spread faster, the virus is no more or less severe than earlier in the outbreak.The study’s authors indicate that the virus has mutated, and that the Spike protein amino acid D614G has become the virus’ dominant strand.“Our global tracking data show that the G614 variant in Spike has spread faster than D614. We interpret this to mean that the virus is likely to be more infectious,” study author Bette Korber of Los Alamos National Laboratory.The federal government’s leading infectious disease expert Dr. Anthony Fauci addressed concerns that the virus could be more contagious in an interview with The Journal of the American Medical Association on Thursday.“The data is showing there’s a single mutation that makes the virus be able to replicate better and maybe have high viral loads,” Dr. Fauci said. “We don’t have a connection to whether an individual does worse with this or not; it just seems that the virus replicates better and may be more transmissible.”Korbe explained in the study how the dominant strand of the virus differs from earlier variants.“In infected individuals G614 is associated with lower RTPCR cycle thresholds, suggestive of higher upper respiratory tract viral loads, although not with increased disease severity,” Korbe said. “These findings illuminate changes important for a mechanistic understanding of the virus, and support continuing surveillance of Spike mutations to aid in the development of immunological interventions.”To read the full study, click here. 1731

A Masai giraffe calf died on Tuesday at the Columbus Zoo in Ohio shortly after its mother, Cami, was given an emergency Cesarean section in an effort to save both the mother and calf. According to the Columbus Zoo, veterinarians and zoo staff recognized that Cami was going into labor Tuesday afternoon, but that the giraffe calf was presenting rear hooves first. The zoo said that it is rare for calves to survive when born rear hooves first.That is when a decision was made for veterinarians to enter Cami's stall. It also meant that a webcam of the birth broadcasted by National Geographic was shut off. Veterinarians from the zoo and Ohio State University first attempted to remove the calf manually. When that did not work, they performed the emergency Cesarean section.Unfortunately, their efforts were futile. "Cesarean sections in giraffes are extremely rare and typically conducted as a last resort due to the high risks involved in putting giraffes under anesthesia and successful recovery," the zoo said in a statement. "After the calf was extracted via Cesarean section, the veterinary team found that the calf had serious congenital defects and thus would not have survived even if it had been born front hooves first."The zoo said Cami’s condition was stable, but her prognosis remains guarded as of late Tuesday evening. Zoo staff will continue to monitor her condition. Tuesday's failed birth marks the second giraffe calf the zoo has lost in recent weeks. On November 17, Ubumwe, an 18-day-old calf died at the zoo. The cause of Ubumwe's death remains unknown, and a full pathology report is being conducted to determine the cause of death. According to information from the Association of Zoos and Aquariums, giraffe calves have a 25 percent mortality rate. This is compared to roughly a 50-percent mortality rate for giraffe calves born in the wild, according to the association.  2007

ADAMS COUNTY, Colo. – Scott Allen Ostrem, the man accused of shooting and killing three people at a Thornton Walmart last week, faces six counts of first-degree murder, 30 counts of attempted first-degree murder and a sentencing enhancer if he’s convicted for the shooting.Ostrem, 47, learned his formal charges at a Monday afternoon hearing in Adams County.Prosecutors charged him with two different counts of first-degree murder for each person he is accused of killing. Three of the counts are first-degree murder after deliberation, while the other three are first-degree murder with extreme indifference.He also faces one count of attempted first-degree murder with extreme indifference for 30 other people who were in the store at the time.The final count against Ostrem is a crime-of-violence sentence enhancer that would apply to the attempted murder charges, District Attorney Dave Young said in court on Monday.Should he be convicted of any of those charges, the sentence enhancer would double any prison and parole time Ostrem faces for each count – from between 8 and 24 years in prison, to between 16 and 48 years in prison for each.The first-degree murder charges are all class 1 felonies in Colorado, meaning Ostrem will face with life in prison without the possibility of parole or the death penalty if he’s convicted on any of those counts.Colorado hasn’t executed anyone since 1997, though three inmates remain on death row. Gov. John Hickenlooper has pledged to not execute anyone while he’s in office, but the state will elect a new governor next November.Should Ostrem face and be convicted of a class 1 felony, like first-degree murder, a separate sentencing hearing would be held to determine if prosecutors would seek the death penalty or not – unless he’s deemed mentally incompetent to be executed.Young told Denver7 Monday it was too early to determine if he'd seek the death penalty, but said he'd consult with the victims' families before making a decision. He also added that other charges are still on the table, but that further investigation was needed before any further charges are filed.Ostrem wore a white-and-yellow striped Adams County Jail jumpsuit in court on Monday. His public defender had a request to redact the victim’s names from the criminal complaint granted by the judge. He said nothing other than replying “yes” to the judge when asked if he understood his charges and the proceedings.The judge also set the preliminary hearing and bond hearing in the case for Feb. 5. A motion by Ostrem’s public defender to seal the jail visitation records was not immediately granted, however. The judge gave District Attorney Dave Young 21 days to respond to the motion.Ostrem's sister called The Denver Post after allegedly receiving death threats about her brother, and told them he'd heard voices in his head for years after an LSD trip.“My brother is not this monster. … He is not cold blooded. He hears these voices. Honestly, in my heart, I believe there is only so much a person can take,” Ostrem's sister, Michelle Willoughby, told The Post. “I never thought something like this would happen.”Law enforcement officials told Denver7 last week they were looking into Ostrem's mental health history.Police arrested Ostrem near 72nd Ave. and Federal Thursday morning more than 12 hours after the shooting occurred. An anonymous citizen tip alerted authorities to his presence in the area, police said, though FBI agents also spotted him in the area. Ostrem was arrested just a few blocks from his apartment.The coroner for Adams and Broomfield counties on Thursday identified the three killed in the shooting as 52-year-old Pamela Marques of Denver, 66-year-old Carlos Moreno of Thornton, and 26-year-old Victor Vasquez of Denver.Moreno's family members were again in court Monday, as some of them were Friday. One told Denver7 outside of court that Moreno had gone to the store with his teenage niece that night, and that the two had briefly split up to look for different things when the shooting happened.Ostrem had a history of run-ins with the police—most recently a driving while ability impaired conviction in Wheat Ridge in 2014. Neighbors said he was “weird” and kept to himself. Another neighbor told Denver7 Ostrem came off as rude and unapproachable.“He was on the edge, not friendly, wouldn’t talk to anybody,” said neighbor Teresa Muniz. “You didn’t dare talk to him, because he always looked mad.”Ostrem walked off his roofing job Wednesday morning in Frederick, the company confirmed, but was otherwise a “good worker,” fellow employees said. He also had several failed businesses, and declared bankruptcy in September 2015.The judge stipulated that Ostrem be held without bond pending the preliminary hearing. The affidavit in the case remained sealed pending redactions, which are expected to be made by the end of day Monday. 4925

After weeks of tensions, China and the United States have reached an initial agreement on trade.Both parties said in a joint statement on Saturday that China has agreed to "significantly increase" purchases of US goods and services, in order to reduce the trade imbalance between the two countries. This was a top demand of the Trump administration during two days of trade talks in Washington with Chinese officials."To meet the growing consumption needs of the Chinese people and the need for high-quality economic development, China will significantly increase purchases of United States goods and services," the statement said. "This will help support growth and employment in the United States."The pledge for more cooperation comes as the US and China, the world's two largest economies, have threatened tens of billions of dollars in tariffs that could lead to a trade war.Both sides also agreed to "meaningful increases" in US agriculture and energy exports, the statement said. The US intends to send a team to China to hammer out the details.The announcement did not put a dollar amount on the commitment from China.US officials on Thursday told CNN that Beijing had proposed boosting Chinese purchases of American goods by around 0 billion. But at a regular news briefing in Beijing on Friday, Chinese Foreign Ministry spokesman Lu Kang denied such an offer had been made. 1394

After multiple news outlets projected that Democrats would take control of the House of Representatives, President Trump called House Minority Leader Nancy Pelosi in a show of bipartisanship, CNN reports.Trump's call came just hours after White House Press Secretary Sarah Huckabee Sanders indicated to pool reporters Tuesday that Trump would not reach out to Pelosi (D-California)."I'm not sure why you would call Nancy Pelosi considering a lot of people in her own party have said they wouldn't support her," Sanders told pool reporters. "If Democrats win tonight, I think we need to wait and see who their speaker is."Trump attacked Pelosi repeatedly while stumping for Republican House candidates in the lead-up to the midterm elections.A number of Democrats have distanced themselves from Pelosi since 2016. Following the 2016 election, Pelosi faced a challenged from Rep. Tim Ryan (D-Ohio) for House Minority leader. 950
