Hurricane Harvey and its aftermath have dumped trillions of gallons of rain across Texas and Louisiana over six days. Homes, office buildings and other structures along the Gulf Coast and in Houston's Harris County, were flooded, their occupants forced to find higher ground. To reach safety, most local residents waded through the murky streams, in some cases for hours.Scientists, including Lane Voorhies, a senior environmental scientist at A&B Labs in Houston, expressed concern about what this water might contain."The potential for contamination is everywhere," Voorhies told Elizabeth Cohen, CNN senior medical correspondent. In particular, he worried about the health effects among people who had spent time in the water, especially those who might have gotten cut while walking through the murky depths. People with underlying illnesses, pregnant women, the elderly and young children would also be more susceptible to illnesses resulting from contact with contaminated water. 997

In a letter sent to 950 patients, University Hospitals Fertility Center blames human error for the loss of 4,000 eggs and embryos, twice the number initially reported.The letter says the Cleveland hospital is “heartbroken” to inform patients it is “unlikely” any of the eggs and embryos are viable.The letter says a remote alarm system on the storage tank containing the eggs and embryos, which was designed to alert a UH employee to temperature fluctuations, was turned off.It is unclear when the remote alarm was turned off, but an alert to an employee as the temperature inside the tank began to rise Saturday night was not sent or received, according to the letter.It is also unclear who turned off the alarm and how long the alarm was turned off.The lab was not staffed March 3, the night of the malfunction. There was also a history of malfunctions involving the storage tank.In the letter, UH said the storage tank in question “needed preventative maintenance.”For weeks prior to the malfunction on March 3, “we experienced difficulty with what is called the liquid nitrogen automatic fill” and were working with the manufacturer to correct the problem.“My clients’ lives and future aspirations were crushed and destroyed. Finding out how simple of a matter it would have been to prevent this tragedy shakes my faith in the medical profession to the core,” said Brian Taubman, an attorney representing patients affected by the malfunction, in a statement to Scripps station WEWS in Cleveland. “My clients trusted UH with their future family, never doubting that those lives were safeguarded and with the flip of a switch their lives and potential lives were changed forever,” said Taubman.The hospital also says it takes responsibility for the failures and apologized several times to the affected patients. The letter says, “Those failures should not have happened, we take responsibility for them – and we are so sorry that our failures caused such a devastating loss for you.”  2015

In a series of unusually candid remarks, the US general in charge of the nation's nuclear arsenal has issued a stark warning that Russia and China are "aggressively" developing new high-speed, or hypersonic, weapons that the US currently has no defense against.The weapons might not be operational for several years, but Gen. John Hyten, the four-star head of US Strategic Command, is warning that changes to missile defenses are urgently needed or the US will be unable to detect them when they are operational."China has tested hypersonic capabilities. Russia has tested. We have as well. Hypersonic capabilities are a significant challenge," Hyten told CNN in an exclusive interview. "We are going to need a different set of sensors in order to see the hypersonic threats. Our adversaries know that."Hyten and other military officials say the current generation of missile detecting satellites and radars won't be enough to detect these new generation weapons. Hypersonic is generally defined as a speed of Mach 5 or over 3,806 miles per hour."We've watched them test those capabilities," Hyten told Congress last week. But with unusual public candor about potential US military shortfalls, he acknowledged "we don't have any defense that could deny the employment of such a weapon against us, so our response would be our deterrent force, which would be the triad and the nuclear capabilities that we have to respond to such a threat."Hypersonic missiles fly into space after launch, but then come down and fly at high speeds on a flight path similar to an airplane. Their lower trajectory make them more difficult for US missile defense satellites and radars to detect. Russia has openly stated it is developing high-speed air-launched missiles as well as underwater hypersonic drones.The Pentagon is currently writing a review of its missile defenses to help determine what new capabilities might be needed to deal with new classes of attack weapons. Hyten gave Congress a hint of what may be in that review stating "the first thing we need is better sensor capability, better tracking capabilities to make sure we can characterize and then respond to that threat."He also called for improved US warheads, essentially "better kill vehicles on the top of our interceptors so that those kill vehicles become more and more lethal." The Pentagon is also working on concepts for interceptor missiles that repel a barrage of enemy attack missiles. Current US missile defenses are designed to only shoot down a small number of enemy missiles.The US focus has largely been to work on hypersonic technologies across the board. But Russia is now well into testing some of its systems. Earlier this month Russia showed video of what the Kremlin said was an air-launched hypersonic ballistic missile.When asked how far along the Russian hypersonic program is, Hyten told CNN, "I don't want to put a who's winning the race, I'll just say there is a race."When asked how soon it could be before the Russians have an operational hypersonic weapon that could reach the US, Hyten said, "It's similar to the North Korea problem. If you continue to pursue that technology, you will get there. And the Russians will get there, the Chinese will get there and we'll get there -- and we'll have to figure out how to deal with that." 3323

In a few weeks, thousands of college students will begin their yearly right of fall by returning to the campus of Tufts University in Medford, Massachusetts, but a return to campus life this year will mean testing and quarantining for those students who chose to come back.Like colleges and universities across the country, Tufts is experimenting with a new plan that will allow more than 5,000 students to come back to campus while at the same time, instituting rigorous new guidelines in an effort to keep COVID-19 from spreading.The key to success, testing.“We wanted to test for COVID at a frequency that would catch people when they’re asymptomatic before they have a chance to spread,” explained Tuft’s President Anthony Monaco.Tufts plan for the fall is as complex as the virus itself. Students from outside the Northeast will be brought back to campus first, where they will be forced to quarantine for 14 days. Health officials expect at least a small portion of those students to test positive for COVID-19 the moment they step back on campus. Because of that, the university has constructed an extra 200 modular units of dorm space. The idea of the modular facilities is to give campus health officials a contained area to monitor students who test positive for the virus, while at the same time, keeping them out of the general population.After students from outside the Northeast are brought back to campus, students from the general area around New England will return.Every single student will be tested twice a week for COVID-19, something experts say will be a key component to safely reopening college campuses this fall. Regardless, school officials expect students to test positive for the virus throughout the fall.Researchers at Yale’s School of Public Health have been advising Tufts and hundreds of other colleges who are planning to resume some form of in-person learning this fall.“If we don’t test frequently, we give silent spreaders an opportunity to grab hold and this virus is hard to play catch-up with,” explained Professor A. David Paltiel, who recently published a study on how quickly the virus can spread through colleges if left unchecked.To study the virus, Paltiel and his colleagues used epidemic modeling to assemble hypothetical situations resembling a college campus. The study found that if you take 5,000 healthy students and add in only 10 students who have COVID-19, hundreds, if not thousands, of kids will be sick by Thanksgiving.“At that point, the only thing that keeps the virus from getting out of control is Thanksgiving break,” he said.That is why testing is key, the study found. When Paltiel took those same 5,000 kids and added in 10 students who have COVID-10, but tested every student twice a week, the study found that only about 100 students ended up catching COVID.“Many universities are planning to only test students who have symptoms, in our view that is a recipe for disaster,” he said.Only adding to the uncertainty of the situation, about 40 percent of college students said they would return to live near campus even if classes were held virtually. Paltiel and other health officials say because of that, it’s more beneficial to have students on-campus where they can be monitored and tested frequently.“It’s hard and it could be a nightmare, people who say we shouldn’t open campuses should remember the nightmare doesn’t go away,” he said. 3420

Immigration and Customs Enforcement agents have released more people seeking asylum in the United States from custody, citing a shortage in space.The release comes as thousands of people fleeing violence in Central America as part of a migrant caravan are beginning to arrive in Tijuana, hoping to enter the U.S. and claim asylum here.Earlier this year, federal officials released several hundred families to relatives, church groups or other organizations due to statutory limitations on how long people can be held in custody."These people, they don't speak English they don't have any money, and they are in another country and they don't have a cell phone to call their relatives," said Magdalena Shwartz, who works with churches and ICE to help find places to stay until relatives can pick up those the government releases.For families detained by immigration authorities, under a settlement agreement and subsequent decision, unaccompanied children or families can only be held in custody for 20 days before being released while their cases work their way through immigration courts.Pastors at a church in Mesa said they recently received a call from ICE asking if the church could help at least one hundred people, who were dropped off Tuesday. Others were given a bus ticket and dropped off at a bus station in Phoenix."They don't have another option," Shwartz said. "They cannot keep the people detained there for a long time, because they are getting more people."Multiple attempts to seek comment from Immigration and Customs Enforcement on Tuesday's release were not returned.Those who are ultimately granted asylum by a judge are allowed to stay, while those whose applications are denied will be deported. 1747
