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...

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...

Ilya Sutskever, OpenAI's co-founder and chief scientist who joined other board members in November to oust Sam Altman, the company's high-profile CEO, has helped found a new artificial intelligence company.The new start-up is called Safe Superintelligence.

The extreme anarchy that has gripped the Gaza Strip is making it too dangerous and difficult to distribute desperately needed aid in the south, aid groups and others say, despite a daily lull in fighting that Israel is seeing along a key road in that area .Days after the pause began, more than 1,000 trucks loaded with supplies remained stranded in Gaza near the Kerem Shalom border crossing with Israel, with thousands of tons of food, medicine and other goods just miles away from Palestinians who had need, aid groups and Israeli officials say. .The threat of looting and attacks by armed gangs have forced humanitarian groups to stop providing assistance in southern Gaza. Trucks traveling on supply routes were riddled with bullet holes. Businessmen sending commercial goods to the territory...

In July 2016, a heat wave hit Boston, with daytime temperatures averaging 92 degrees for five consecutive days. Some local college students staying in town for the summer got lucky and lived in dorms with central air conditioning. Other students not so much: They were stuck in older dorms without air conditioningJose Guillermo Cedeño Laurent, a Harvard researcher at the time, decided to take advantage of this natural experiment to see how heat, and especially night heat, affected the cognitive performance of young adults. He asked 44 students to take math and self-monitoring tests five days before the temperature rose, every day during the heat wave and two days after.“Many of us think we are immune to heat,” said Dr. Cedeño, now an assistant professor of environmental and occupational ...
