Investments in Israel's tech sector dropped by nearly half in 2022, reflecting a global economic slowdown, a nonprofit group reported.

Startup Nation Central, which tracks the industry in Israel, said the total value of investments in the tech sector sank from an all-time high of $27 billion in 2021 to about $15.5 billion last year. The tech industry accounts for more than half the country's exports, according to official data.

Twitter says it will ease up on its 3-year-old ban on political advertising, the latest change by Elon Musk as he tries to pump up revenue after purchasing the social media platform last year.

The company tweeted late Tuesday that "we're relaxing our ads policy for cause-based ads in the US."

The threat from transnational extremist right-wing communities online leading to violent attacks is rising, Europe's policing agency warned Monday, after an operation flagged more than 800 examples of violent or terror content. 

Jordan has announced it was imposing a "temporary ban" on the social media platform TikTok, a day after a police officer was killed during clashes with protesters that broke out over high fuel prices.

Truck drivers launched a strike last week to protest high fuel prices in the Arab kingdom. The strike and protests have spread to several cities across Jordan. Clashes erupted in multiple cities on Thursday, with police using tear gas to disperse them.

Twitter on Wednesday suspended an account that used publicly available flight data to track Elon Musk's private jet, despite a pledge by the social media platform's new owner to keep it up because of his free speech principles.

Then, hours later, Musk brought back the jet-tracking account after imposing new conditions on all of Twitter's users — no more sharing of anyone's current location.

A hacker who reportedly posed as the CEO of a financial institution claims to have obtained access to the more than 80,000-member database of InfraGard, an FBI-run outreach program that shares sensitive information on national security and cybersecurity threats with public officials and private sector actors who run U.S. critical infrastructure.

The hacker posted samples they said were from the database to an online forum popular with cybercriminals last weekend and said they were asking $50,000 for the entire database.

TikTok's algorithms are promoting videos about self-harm and eating disorders to vulnerable teens, according to a report published Wednesday that highlights concerns about social media and its impact on youth mental health.

What you're seeing in your feed on Twitter is changing. But how?

The social media platform's new owner, Elon Musk, has been trying to prove through giving selected journalists access to some of the company's internal communications dubbed "The Twitter Files" that officials from the previous leadership team allegedly suppressed right-wing voices.

NASA's Orion capsule made a blisteringly fast return from the moon Sunday, parachuting into the Pacific off Mexico to conclude a test flight that should clear the way for astronauts on the next lunar flyby.

The incoming capsule hit the atmosphere at Mach 32, or 32 times the speed of sound, and endured reentry temperatures of 5,000 degrees Fahrenheit (2,760 degrees Celsius) before splashing down west of Baja California near Guadalupe Island. A Navy ship quickly moved in to recover the spacecraft and its silent occupants — three test dummies rigged with vibration sensors and radiation monitors.

Three Chinese astronauts docked early Wednesday with their country's space station, where they will overlap for several days with the three-member crew already onboard and expand the facility to its maximum size.

Docking with the Tiangong station came at 5:42 a.m. Wednesday, about 6 1/2 hours after the Shenzhou-15 spaceship blasted off atop a Long March-2F carrier rocket from the Jiuquan Satellite Launch Center.
