HONG KONG – Scientists at the University of Hong Kong claim to have the first evidence of someone being reinfected with the coronavirus that causes COVID-19.They said Monday that genetic tests show a 33-year-old man returning to Hong Kong from a trip to Spain in mid-August had a different strain of the virus than the one he’d previously been infected with in March.The man had mild symptoms the first time and none the second time, so his previous infection may have helped prevent serious illness.Experts say waning immunity could have implications for vaccine development and that the case shows the need to keep up social distancing and other prevention measures.Dr. Kelvin Kai-Wang To, who led the group of scientists, told The Associated Press that it’s unknown how many people can get reinfected, but there are probably more out there.Even if someone can be infected a second time, it’s not known if they have some protection against serious illness, because the immune system generally remembers how to make antibodies against a virus it’s seen before. 1069

From New York City to Fargo, North Dakota, cities across the United States say they are issuing curfews to keep the peace.A curfew allows police the ability without any other reason to threaten to arrest or detain crowds of protesters that linger or groups that appear to be a danger to order.These curfews can be a deterrent to get law-abiding citizens to head home and allow law enforcement to focus their efforts on the unrest, not getting bogged down with simple violations.But the deadlines aren’t hard and fast — many of them have exceptions for people heading to and from work, reporters, public transportation and even people buying groceries.Many protesters have routinely disregarded the curfews, and some police departments have actually allowed peaceful demonstrations to continue even after curfew while focusing their attention on violent unrest.Curfews like these are commonly used in natural disasters like hurricanes, floods and tornadoes to allow police to stop anyone on the streets and prevent stealing or looting.Some civil rights organizations think hastily issued curfews are unfair and against the First Amendment. The American Civil Liberties Union of Northern California argued that curfews give police too much discretion over whom to arrest, The Associated Press reports. 1307

Hackers who were able to take control of at least a dozen high-profile Twitter accounts and tweet messages calling for Bitcoin solicitations gained access to the accounts by targeting Twitter employees, the social media site said Wednesday evening.According to Twitter's support account, the hackers "successfully targeted some of our employees with access to internal systems and tools." They then posted messages seeking Bitcoin solicitations — with a promise to return double the amount — on a series of high-profile Twitter accounts.CNN reports that the Bitcoin wallet included in the tweets is in fact, real and that those conducting the scam have received more than 0,000 in Bitcoin. 700

Goats are such an enigma. They're supposed to be crafty, and yet here we see two of them stranded on a precarious section of a Pennsylvania overpass. The only explanation is that they wanted to be there, knew exactly what they were doing, and were irritated when some good-hearted policemen and state employees showed up to get them down.The goat rescue happened Tuesday on the Mahoning River Bridge in western Pennsylvania. It was a unique experience for all involved."We've never had goats on a bridge before," Pennsylvania Turnpike spokesperson Renee Colborn told CNN. 579
