Attorneys general from several states plan to jointly file new antitrust litigation against Facebook in the coming days, according to reports from CNBC and the Wall Street Journal.According to CNBC, as many as 40 states are expected to join New York in suing the social media giant. The report also says that the Federal Trade Commission could file a separate but related complaint in district court.While the specifics of the pending lawsuit are unclear, Facebook has been criticized for swallowing up competitors, like Instagram and WhatsApp for fairly reasonable prices.The pending lawsuit would mark the second significant piece of legislation filed against a Silicon Valley giant in recent months. In October, the Justice Department sued Alphabet, the parent company of Google, and alleged the company is a search engine monopoly. 843

atThe NFL's TV ratings are down so far this season and if that news isn't distressing enough for the biggest ratings driver on TV, the lest slump follows a 2016 season marked by unstable ratings that had pundits and analysts scratching their heads.So is it time for the league and its TV partners to panic once again? The answer is that it's simply too early to tell.Brian Hughes, a senior vice president at Magna, which monitors audience trends, believes Hurricane Irma impacted viewership during the NFL's first week. There's also not enough of a sample size of games to make an true assessment of the league's viewership so far, he said.But the ratings slump could also be a sign of disruptive media trends on the horizon. 733

AstraZeneca is the latest drugmaker to announce promising Phase 3 trial results from its COVID-19 vaccine candidate.On Monday, AstraZeneca said its two-shot vaccine candidate has been 90% effective thus far along with no safety concerns.“These findings show that we have an effective vaccine that will save many lives," said Professor Andrew Pollard, the chief executive of the study. Excitingly, we’ve found that one of our dosing regimens may be around 90% effective and if this dosing regime is used, more people could be vaccinated with planned vaccine supply. Today’s announcement is only possible thanks to the many volunteers in our trial, and the hard working and talented team of researchers based around the world.”The company added in its press release that its vaccine candidate offers two distinct advantages over vaccines made by Pfizer and Moderna — it's cheaper to produce, and does not need to be stored in ultra-cold conditions before use.AstraZeneca added that the company would "immediately" prepare regulatory paperwork to seek Emergency Use Listing status from the World Health Organization.AstraZeneca is just the latest drug company to report encouraging results from its COVID-19 vaccine candidate.Last week, Pfizer said it had submitted Emergency Use Authorization paperwork to the Food & Drug Administration (FDA) after a final analysis of its vaccine candidate proved to be 95% effective in preventing COVID-19. The FDA is expected to approve the drug in the coming weeks.Moderna has also said that early results show its vaccine candidate to be 95% effective, and is on track to have the drug approved for Emergency Use Authorization by the end of the year.AstraZeneca, Pfizer and Moderna are all shattering records for vaccine development. The three vaccines are all on track to be approved for widespread use in uder a year. Typically, it takes several years for a vaccine to go from development to approval.The announcement comes as COVID-19 is spreading around the world at a rate not previously seen since the pandemic began. And while all three companies are pre-producing their vaccines in the hope that it will be approved, health experts warn that they won't be widely available until spring 2021. 2247

AVALON, Calif. (AP) — The nonprofit organization that owns a majority of California’s Santa Catalina Island plans to boost eco-tourism by adding more bison to existing herds, recharging a debate over their environmental impacts. The Los Angeles Times reports the Catalina Island Conservancy says there has not been a bison calf born on the island in seven years and the herd size has dwindled to 100. The conservancy board is working to bring two pregnant bison to the island. A biologist says bison herds stay on isolated patches of grass and adding more animals will not result in more bison sightings by eco-tourists. 628

As the COVID-19 pandemic progresses, researchers say it is important to track how the coronavirus mutates because it could affect the efficacy of a vaccine.Like all living cells, viruses evolve their chemical make-up changes. In viruses like the flu, that happens frequently, which is why every year there is a new vaccine to treat whatever strain is expected to circulate. With COVID-19, however, those mutations happen much slower, according to research out of Arizona State University.“One of the things we’re still keeping an eye on is the evolution of this virus because that virus is still around in the community,” said Dr. Efrem Lim, an assistant professor at ASU. “Everyone is coming in blind to this. This is a novel virus. This isn’t something we have seen before.”In March, Arizona State University played host to our country’s fourth COVID-19 case. As soon as it was detected, Dr. Lim started studying how the virus mutates and sent his findings to the World Health Organization. It's something that still continues to this day.“This virus, overall, mutates pretty slowly, which is a good thing,” said Dr. Lim. “However, we can have instances where the virus can have very large, dramatic, mutations, such as deletions in the genome.”While rare, Dr. Lim says those mutations can be significant as it changes how the virus acts inside the body.Currently, scientists are focusing much of their efforts on identifying ways to eliminate the function of the spike protein in COVID-19, as it is the way the virus binds to our cells and infects them (spike proteins are the stalks that protrude from the center of the virus that make it so recognizable).“It is very good news that the virus is not changing rapidly,” said ASU virologist Dr. Brenda Hogue. “We will have to see over time, as the virus continues to circulate, as we put a vaccine into play, whether or not there will be any issues.”Dr. Lim says right now there does not appear to be any issues because the virus mutates slowly, but he adds it could adapt to a vaccine once one begins to circulate.He says more testing needs to be done to determine that, however. 2140
