Authorities in India have decided to hold off retrieving the body of the American national feared killed on North Sentinel Island amid concerns about a possible confrontation with the tribe that lives there.John Allen Chau is believed to have been killed by Sentinelese tribespeople after he visited their island home in the Andaman and Nicobar archipelago in November, breaching local laws strictly prohibiting contact with the isolated people.Indian police say Chau found local fishermen who agreed to take him near the island, before using a canoe the rest of the way. Days later, the fishermen -- who have since been arrested for facilitating his trip -- say they saw the tribespeople dragging his body around the island."We want to avoid direct confrontation with the tribespeople," Dependra Pathak, director general of police of the Andaman and Nicobar islands, told CNN when asked about the latest efforts to retrieve Chau's body. "We do not want to go there and create an unhappy situation."The decision to avoid a direct confrontation with the isolated tribe came after a series of meetings and reconnaissance trips made by the officials. Anthropologists and tribal experts were also consulted.By Sunday, authorities had mapped out the area with the help of the fishermen and observed several members of the tribe walking around the area where eyewitnesses claim to have seen Chau's body dragged and buried.However, despite ruling out any immediate attempts to land on the island, local police would not categorically rule out retrieving the body at a future date. "We are working on it. We'll firm up a plan very soon," said Pathak. 1650

Authorities believe they have found a package addressed to former Vice President Joe Biden that was considered suspicious due to its similarities to other packages sent this week to prominent Democrats and CNN, law enforcement officials said Thursday.The package was misaddressed and returned to sender, two law enforcement sources previously told CNN.Also on Thursday, a suspicious package addressed to actor-director Robert De Niro was reported at the Manhattan building where his production company is based, and its marking and contents appear similar to pipe bomb packages recently mailed nationwide to top Democrats, two law enforcement sources said.Law enforcement authorities are treating the series of bombs as a domestic terror matter and are advising the public to remain vigilant.Devices sent to former President Barack Obama, Hillary Clinton, former Attorney General Eric Holder, California Democratic Rep. Maxine Waters and Democratic donor George Soros showed the presence of a sulfur substance, which could have exploded, a law enforcement official said.The devices are believed to be pipe bombs, inherently unstable, and at risk of being set off just by handling.The FBI's counterterrorism division is leading the investigation Thursday into the packages and the agency says it's possible additional packages were mailed to other locations.The motive is unknown, but the recipients are all prominent targets of right-wing criticism and, in many cases, of President Donald Trump himself. The package found at CNN's New York bureau in the Time Warner Center was addressed to former CIA Director John Brennan, city and local law enforcement officials said.At the White House, Trump vowed Wednesday that "we will spare no resources or expense" to pursue the perpetrator.The-CNN-Wire 1803

As students begin to head back to the classroom – either virtually or in person – this month begins the most uncertain school year in recent memory.While some public health experts have expressed apprehension about reopening schools, President Donald Trump gave a full-throated defense for bringing back students into classroom full time this fall. Trump hosted a group of educators and school administrators at the White House on Wednesday.Amid Trump’s effort to reopen schools, the CDC released updated guidance last month that emphasizes reopening schools. The new guidance contradicts previous guidance, which recommended closing schools during periods of substantial community transmission.The updated guidance said that extended school closures are harmful to children and can lead to severe learning loss, and the need for in-person instruction is particularly important for students with heightened behavioral needs.During an event with educators on Wednesday, Trump said not only should students return to the classroom, but he decried hybrid schedules, which incorporates a blend of in-person and virtual learning. Proponents of hybrid schedules say that they allow for students to have some in-person learning while opening more classroom space for social distancing.But the president is not a fan.“The concept of every other day seems a little ridiculous, right?” Trump said. “If you are going to do it, you do it. If you are not going to do it, the concept of going back even from a management standpoint from the school, every other day seems very strange.”Trump once again called on Congress to pass 5 billion in education funding, which House Democrats have also pushed for as part of a broader stimulus plan. While Treasury Secretary Steven Mnuchin said the White House is open to doing a piecemeal approach to a stimulus package, House Democrats have pushed for an all-encompassing bill.Some of the funding for schools could be used to help districts with additional costs associated with mitigating the risk of the virus.Trump said that the funds should follow the students. He has previously said that if schools opt for online learning, they should not receive federal funds.“If the school is closed, you know, why are we paying if a school is closed?” Trump asked. “Why are we paying the school if it is closed? I would rather give it to the student, the parents, and you do your own thing, and to me it makes a lot of sense.”While Trump is eager for a full return to school, there are several cautionary anecdotes from several districts that opened earlier this month.Most notably, the Cherokee School District in Georgia reported on Tuesday 59 students and employees tested positive for the coronavirus following its reopening. The district is now asking 925 employees and students to quarantine for two weeks. The district’s Etowah High School will remain closed until August 31 due to the outbreak. 2935

As we're all focused on the current rollout of the COVID-19 vaccine, a technology known as thin-film freezing is getting a lot of attention. It's groundbreaking and could change the way we administer drugs or use medicine in general.You've probably heard about the need to keep the COVID-19 vaccine cold. It has to be so cold, in fact, that the shipment and transport are challenging. Well, what if that vaccine could be turned into powder?“What we’ve most recently been working on is the elimination of cold chain by storing as a powder, a dry powder where the drug is much more stable than if it was stored as a liquid or as a frozen liquid,” said co-inventor Dr. Robert Williams.Williams said it would eliminate the need for extreme cold storage and transport. The technology isn't new. He got a research grant and came up with it about 15 years ago.Williams, who is also a pharmacy professor at the University of Texas in Austin, said they were working on the technology and its multiple uses when the pandemic hit. And all of a sudden, they got a lot of attention.“We have published over 70 papers on the technology and using it for different products- it’s quite a mature process," Williams said. "We developed it because with other vaccines, the majority of the vaccine cost is in wastage because of this cold chain issue, so we published several key papers where we showed our thin-film freezing technology would protect vaccines - and you wouldn’t need cold chain storage.”Glenn Mattes, President, and CEO of TFF Pharmaceuticals added that the powders can be converted to topical preparations and they are currently working with the US Army to take some of the preparations and would then administer them directly through the eye.TFF is launching thin-film freezing into development through the FDA process. “I use the term ubiquitous because it is and disruptive because it is,” Mattes said. He added that they've explored their technology in the cannabinoid realm. But, as for the COVID vaccine, they're aiming for a second-generation usage.“To truly eradicate the pandemic, you have to have a global response," Mattes said. "The companies we’ve been speaking to certainly recognize the broad utilization of the technology but the application to the developing world, rural area, remote areas, where you can take a powder and inhale it or take the powder and reconstitute it has tremendous potential."Experts say it is only just the beginning as they launch their technology into a new world. 2511
