A fist fight during rush hour at a busy Omaha intersection was caught on cell phone video by another driver. The road rage footage shows two drivers blocking traffic to fight. The incident happened around 4 p.m. Tuesday, but it's unclear what events led up to the fight. The video shows the two men outside of their cars and exchanging blows before the men went into their separate vehicles and drove away.   441

A glacier in Italy is turning pink. The color is caused by algae growth — and scientists worry it will make the glacier melt faster, because darker colors absorb more radiation.Past studies report 50% of ice in the Alps' glaciers will be gone by 2050 because of climate change. pic.twitter.com/cgGwWQcG81— AJ+ (@ajplus) July 7, 2020 340

A major hospital system is managing the fallout of what may be the biggest medical cyberattack in U.S. history.United Health Services says its company-wide network is currently offline due to a suspected ransomware attack.Ransomware is when criminals encrypt files and demand money for a key to unlock them again.Experts say hospitals may be more susceptible while fighting the coronavirus.“Medical record and medical care facilities are prime targets, not only because of the high value of the information, but also because of the fact that people are terribly busy,” said Alan Katerinsky, a clinical assistant professor at the University at Buffalo.It's not just hospitals. Cyber-attack attempts are up about five times since the pandemic started.People working from home don't have the same corporate protections that are normally in place in an office. IT workers may also be remote.“It might be more difficult to work from home and notice things that are going on, instead of just being on-site, on the premises, and seeing what's going on, on an ongoing basis,” said Steve Beaty, a professor of computer sciences at MSU Denver.After a ransomware attack, if an organization doesn't pay to get their files back, they still have to pay for the cleanup.The criminal may retaliate by releasing the private information, like what happened to a school district in Las Vegas this week.There's recently been talk of legislation to make it illegal to pay such ransoms, which may help deter criminals.“They've upped their game partially because maybe they're seeing that there is going to be a limited amount of time this is actually going to work, at least in some jurisdictions,” said Beaty.Cyber criminals often get in through phishing emails, so training to recognize harmful links may help.Companies can also run tests to see if there are vulnerabilities in their systems, but that's more expensive.It's also important for remote workers to use a VPN for privacy. 1971

A Chinese court has banned the sale and import of most iPhone models in a stunning decision sure to escalate the nasty trade war between the United States and China.The ban does not cover the new iPhone XS, iPhone XS Plus or iPhone XR, which were not yet available when Qualcomm filed its lawsuit. The phones covered by the ban make up about 10% to 15% of current iPhone sales in China, according to Daniel Ives, analyst at Wedbush Securities.The court granted a pair of preliminary injunctions requested by Qualcomm, an American microchip maker. Qualcomm claims that Apple violates two of its patents in the iPhone 6S, iPhone 6S Plus, iPhone 7, iPhone 7 Plus, iPhone 8, iPhone 8 Plus and iPhone X. The patents allow people to edit and resize photos on a phone and to manage apps by using a touchscreen, according to Qualcomm.The practical effect of the injunction is not yet clear. The ruling was announced publicly Monday but put into effect last week, but Apple said in a statement that all iPhone models remain available in China."If Apple is violating the orders, Qualcomm will seek enforcement of the orders through enforcement tribunals that are part of the Chinese court system," Don Rosenberg, general counsel for Qualcomm, said in a statement.Apple accused Qualcomm of playing dirty tricks, including asserting a patent that had already been invalidated by international courts, and other patents that it had never before used. Apple said it will pursue a legal response in court."Qualcomm's effort to ban our products is another desperate move by a company whose illegal practices are under investigation by regulators around the world," Apple said.Apple on Monday filed a request for the court to reconsider its decision. Qualcomm applauded the ruling, saying Apple owes it money for using its technology."We deeply value our relationships with customers, rarely resorting to the courts for assistance, but we also have an abiding belief in the need to protect intellectual property rights," Don Rosenberg, general counsel for Qualcomm, said in a statement. "Apple continues to benefit from our intellectual property while refusing to compensate us."Investors were mostly unmoved. Apple's (AAPL) stock was about flat Monday afternoon. Qualcomm's (QCOM) stock rose 2%.  2293

A Florida representative's aide lost his job Tuesday after sending an email to a reporter falsely alleging that two students who survived the Florida school shooting -- and were speaking out on TV -- are "actors."Benjamin Kelly, who worked as district secretary for Florida State Representative Shawn Harrison, emailed a Tampa Bay Times journalist with a message that read: "Both kids in the picture are not students here but actors that travel to various crisis when they happen."Several Marjory Stoneman Douglas High School students who have advocated for stricter gun laws, have become the subject of conspiracy theories and smear campaigns.  658
