TikTok explained Thursday why it believes a new federal law that could lead to a ban on the popular video app in January is unconstitutional, calling the legislation an "extraordinary restriction on free speech."The company said Congress has not given the law — which would force TikTok's Chinese owner to sell the popular social media app or face a ban in the United States — with nearly enough scrutiny and attention.TikTok made the arguments in a filing with the U.S. Court of Appeals for the District of Columbia Circuit, where the company sued to block the law in May.“This law represents a radical departure from this country's tradition of supporting an open Internet and sets a dangerous precedent that allows political branches to target an unfavorable speech platform and force it t...

The only way for almost all Gazans to escape the horrors of the war between Israel and Hamas is to flee through neighboring Egypt.And this is usually a complicated and expensive task, involving paying thousands of dollars to an Egyptian company that can put Palestinians on an approved travel list to cross the border.Faced with high societal tariffs, as well as widespread hunger in Gaza, where there is no end in sight to Israel's military campaign, many Palestinians have resorted to trying to raise money with desperate appeals on digital platforms like GoFundMe.Dr. Salim Ghayyda, a pediatrician from northern Scotland, issued one such appeal in January after his sister texted him from Gaza to say their father had been having seizures.Their father arrived at hospital and survived, but Dr ...

Doctors and physical therapists have long incorporated aerobic exercise into treatment programs for low back pain. Movement can relieve lower back pain and at the same time strengthen the muscles that support your back. However, many people with back pain may be reluctant to exercise.A new study, published Wednesday in The Lancet, offers further evidence about the power of the movement. The study found that regular walking can be very effective in preventing back pain from recurring. The study focused on adults with a history of low back pain; those who walked regularly walked almost twice as long without back pain returning compared to the control group.The new findings align with a large body of existing research that has established an association between physical activity and bett...

The European Union has agreed to a new round of economic sanctions against Russian individuals and companies, the Belgian government said on Thursday. In particular, they include measures aimed at squeezing Russia's profits from the sale of liquefied natural gas to EU members.Most EU countries stopped importing natural gas arriving by pipeline from Russia soon after the full-scale invasion of Ukraine in February 2022. But the bloc had refrained from launching formal sanctions against the imports of Russian gas, leading many EU countries to purchase LNG from Russia, which arrives by ship.The latest action includes measures against imports of Russian LNG passing through EU ports to other countries, known as transshipments, said a senior EU diplomat familiar with the deal who spoke on co...

After days of intense clashes between Hezbollah and Israel, Hassan Nasrallah, the leader of the Lebanese militia, warned on Wednesday that "there will be no place safe from our missiles and our drones" if an all-out war breaks out. He also threatened Cyprus if it allowed Israel to use its airports and bases in a full-scale conflict.“The enemy knows very well that we have prepared for the most difficult days, and he knows what he will face,” Nasrallah said. “If war is imposed, the resistance will fight without constraints, rules or limits.”President Nikos Christodoulides of Cyprus responded to the threat by saying his country was “absolutely not involved in any way,” according to comments posted on social media.In his first public statements amid the recent outbreak of violence along the...

When President Vladimir V. Putin travels abroad — as he did this week to North Korea and Vietnam to strengthen alliances and cultivate security ties amid Russia's war in Ukraine — he usually flies on Ilyushin-series jets Il-96 dated to Soviet design.With his latest trip coming shortly after plane crashes that killed two other world leaders, President Ebrahim Raisi of Iran and Vice President Saulos Chilima of Malawi, a Kremlin spokesperson found it necessary recently to reassure the Russian public that Putin's planes were “very reliable. "Although Russian airlines have abandoned Ilyushin models in favor of new Western models – neither of the country's two major airlines, Aeroflot and Rossiya, currently list any Ilyushin planes in their commercial passenger fleet – Putin appears...
