Three months ago, Tree of Life Rabbi Hazzan Jeffrey Myers took to his congregation's blog and bemoaned the scourge of gun violence and the failure of lawmakers to address the problem.Three months later, that menace entered his sanctuary. A gunman stepped into the Pittsburgh synagogue as congregants observed Shabbat. Multiple casualties were reported, including congregants and police. At least four people died and a suspect has been taken into custody.Myers' message this summer now represents grim relevance for his congregation, a religious community affiliated with the Conservative branch of Judaism and is located in Squirrel Hill, the city's well-known Jewish enclave."Despite continuous calls for sensible gun control and mental health care, our elected leaders in Washington knew that it would fade away in time," Myers wrote in a blog post last July titled "We Deserve Better" that made reference to the massacre at Stoneman Douglas High School in Parkland, Florida. 986

Thursday marks six months since the World Health Organization declared COVID-19 a global health emergency. The coronavirus is only the sixth time a global health emergency has been declared.Compared to the previous five emergencies, experts say the coronavirus pandemic is easily the most severe.Here in the United States, we’re still far behind when it comes to recovery. Health security experts at Johns Hopkins University say we have seen some success in treating the virus, but there hasn't been much success in responding to it, especially when it comes to testing.“Many states did not invest in testing and many states did not invest in contact tracers, so when you see cases spiral out of control in certain states, it's not surprising to me,” Dr. Amesh Adalja of Johns Hopkins University said. “That's exactly the recipe you would set up if you wanted cases to rise.”Dr. Adalja says in order to tackle the spread of the virus, the US needs to prioritize testing, tracing and isolating.Health experts across the country have also signed a letter calling on the US to shut down the country and start over. The letter includes a list of recommendations for what's needed before cities can reopen. It calls for enhanced testing capabilities, more contact tracers and more personal protective equipment.Dr. Bill Hanage at Harvard University was one of those who signed the letter, and says safely reopening can happen, “If we look at countries like New Zealand, South Korea, then you can actually see that it is possible with sustained action to shut down, strangle the virus, throw it back to the sea, and then you can open with substantial amounts of normal economy.”Hanage adds that while it can be done, it's yet to be seen if the US is capable of doing this.The Association of American Medical Colleges has also offered a road map that would change the country's approach to the pandemic. It calls for some of the same things other doctors have asked for -- testing, tracing, and more PPE.It also goes further and asks for broad health insurance coverage for people who have lost their jobs, remedying drug shortages, and establishing national standards on face coverings. 2188

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

There’s a new way to take an Uber and as long as you don’t mind a little walking it’s the cheapest option.Express Pool is the latest option for taking an Uber. Once you plug in your location, the new option will pop up on the bottom far left of your screen.A quick trial test of Express Pool found the service to be a dollar cheaper than Uber Pool. However, you'll have to walk a block or two to be picked up by your driver.The logic behind the new service is to help Uber drivers be able to drive in a straight line to pick up pool passengers. That way, there are no out-of-the-way stops.However, it could mean for a slower pickup time. Also, with any Pool ride from Uber, you will most likely share the ride with other riders.Despite walking out of the way and waiting a bit longer, a test of Express Pool still got riders to their destinations on time.  894
