A jaw-dropping new study published in The Lancet on Thursday is turning everything cardiologists thought they knew about heart stents upside down. Stents — tiny mesh wires used to prop open blocked arteries — are used to prevent heart attacks, or to relieve chest pain that patients experience due to a lack of blood to the heart muscle. According to the study, stents actually do very little — and possibly nothing at all — to prevent that heart pain.

In the study, 200 patients were either given stents or a placebo surgery as if they were receiving a stent, only to not have the mesh actually inserted. All the patients were also put on drugs to reduce the risk of heart attack and to open blood vessels. "When the researchers tested the patients six weeks later, both groups said they had less chest pain, and they did better than before on treadmill tests," The New York Times writes. "But there was no real difference between the patients, the researchers found. Those who got the sham procedure did just as well as those who got stents."

One reason for the baffling results could be that stenting only the largest blockages in the heart does not make a significant difference in a disease that affects the whole muscle. While one artery might be reopened with stents, blockages could obstruct other vessels later.

"All cardiology guidelines should be revised," wrote Dr. David L. Brown of the Washington University School of Medicine and Dr. Rita F. Redberg of the University of California, San Francisco, in a review of the study. Redberg added that based on her assessment, stents should only be given to people who are actually having heart attacks, especially since the surgery carries risks for patients.

More than 500,000 people around the world are given stents each year to relieve chest pain. Read the report at The New York Times. Jeva Lange

Syrian government strikes have killed some 500 civilians, including about 120 children, over the course of a week in the East Ghouta suburb of Damascus, reports the Syrian Observatory for Human Rights. The activist group says Russian planes are assisting with the attacks, but Russia denies direct engagement.

Syrian President Bashar al-Assad's forces reportedly used barrel bombs and artillery shells to target the area where some 400,000 people have no option of escape. Civilians are "being forced into bunkers and many of them can't even find the time to bury their dead," reports NPR's Lama Al-Arian. The Assad regime says its goal is to liberate civilians from a nearby rebel enclave.

United Nations Secretary-General Antonio Guterres is pushing for a U.N. resolution implementing a 30-day ceasefire so humanitarian aid can be delivered to East Ghouta. "I am deeply saddened by the terrible suffering of the civilian population," he said, describing the situation as "hell on Earth." If the resolution passes — Moscow is demanding edits in exchange for its support — its prospects for enforcement are dubious.

Delta and United Airlines on Saturday announced they are cutting ties with the National Rifle Association (NRA).

The airlines join the Avis, Hertz, Enterprise, Alamo, and National car rental brands as well as First National Bank of Omaha, Best Western hotels, MetLife insurance, and more than a dozen other companies in ending deals with the NRA. Delta previously offered discounted airfare for NRA members, and United offered discounts on flights to and from the organization's annual conference.

Companies are distancing themselves from the NRA in response to outrage following last week's mass shooting at a Parkland, Florida, high school. Customer responses to the tweeted announcements were predictably mixed. Bonnie Kristian

A daring squirrel narrowly cheated death Saturday while attempting to sprint across the course of the women's parallel giant slalom competition at the Winter Olympics in Pyeongchang, South Korea.

Austrian snowboarder Daniela Ulbing just barely maneuvered around the animal, which appeared to reconsider its choices after she passed. Watch the squirrel's moment of destiny below. Bonnie Kristian

Billionaire Warren Buffett published his annual letter to shareholders of Berkshire Hathaway on Saturday. Berkshire's net worth grew by $65.3 billion in 2017, Buffett said, but $29 billion of that gain came from savings effected by the Republican tax plan passed in December. The new tax law lowered the nominal corporate tax rate from 35 to 21 percent.

For individual investors, Buffett cautioned against going into debt to purchase stock because the market may drop. "There is simply no telling how far stocks can fall in a short period," he wrote. "Even if your borrowings are small and your positions aren't immediately threatened by the plunging market, your mind may well become rattled by scary headlines and breathless commentary. And an unsettled mind will not make good decisions."

The Department of Agriculture (USDA) on Friday began soliciting public input on restoring work requirements for food stamp recipients in high-unemployment areas where rules were waived in recent years.

"Long-term dependency has never been part of the American dream," said Agriculture Secretary Sonny Perdue. "USDA's goal is to move individuals and families [using food stamps] back to the workforce as the best long-term solution to poverty."

Able-bodied adults without dependents (ABAWDs) are eligible for only three months of food stamps through the Supplemental Nutrition Assistance Program (SNAP) unless they spend at least 80 hours per month working or at a qualified training. In five states — Alaska, California, Louisiana, Nevada, and New Mexico — and economically struggling localities in 28 other states, that rule is currently suspended.

No changes have been formally proposed at this time, but the USDA estimates about 2.9 million ABAWDs are currently unemployed and would therefore be affected if the waiver were rescinded. They make up about 7 percent of the 43.6 million people who used food stamps in 2017. Bonnie Kristian

Heavy rains over the weekend are expected to exacerbate deadly flooding in the Midwest and southern Plains regions. Hundreds of people have evacuated their homes in affected areas from eastern Texas through southern Indiana, and at least three people, including one child, have been killed in connection to the floods.

Kentucky Gov. Matt Bevin (R) has declared a 30-day state of emergency, and Illinois Gov. Bruce Rauner (R) has issued a disaster proclamation for three counties. The National Weather Service advises caution of flash floods and tornadoes throughout the weekend. Bonnie Kristian

The United States men's curling team took its first-ever gold medal at the Winter Olympics in Pyeongchang on Saturday. After nearly being eliminated from the competition, the team made a comeback win, besting both the Canadian team — prior to this victory, no American team in men's or women's curling has ever beaten Canada at the Olympics — and the Swedish team, which was ranked first in the world.

"During the entire end we could kind of feel it building," said team leader John Shuster of the gold-medal victory over Sweden. "Their margin for error got really small."

Also Saturday, Ester Ledecka of the Czech Republic became the first woman to take gold in two separate events at the Winter Games. Last Saturday, she was the surprise victor in Alpine skiing, and this week, Ledecka triumphed in her primary event, women's parallel giant slalom snowboarding. Bonnie Kristian
