This week in odd scientific studies: Researchers at the U.K.'s University of Warwick found that the Danish may be happier than other people thanks to their genetics.

Denmark regularly leads polls of the world's happiest countries, the study authors said, and they wanted to look into why, exactly, this was true. Last year's World Happiness Report ranked Denmark as the happiest nation on Earth, and researchers found that people who have Danish ancestry are more likely to have a positive life outlook.

Researchers at the university's Centre for Competitive Advantage in the Global Economy (CAGE) looked at data from 131 countries and found that nations genetically closer to Danes had happier residents. The research, published in a working paper by the German economic research institute IZA in its Discussion Paper series, found that Danish birth was correlated with a gene that influences serotonin — a mood chemical — levels in the brain. The greater a nation's genetic distance was from Denmark, the lower that nation's reported well-being was.

When compared with people from other countries, the Danish were less likely to possess a short version of the gene, which has been linked to lower levels of life satisfaction. While the researchers controlled for personal income and religion, those with Danish genetics were still found to be happier.

"It seems there are reasons to believe that genetic patterns may help researchers to understand international well-being levels," Andrew Oswald, one of the researchers behind the project, said in a statement. "More research in this area is now needed and economists and social scientists may need to pay greater heed to the role of genetic variation across national populations." Meghan DeMaria

Baltimore Mayor Stephanie Rawlings-Blake announced Sunday that she was lifting a city-wide 10 p.m. curfew, which had been in effect in Baltimore for five nights. The curfew came after riots protesting the death of Freddie Gray, who died while in police custody.

"I have rescinded my order instituting a city-wide curfew," Rawlings-Blake announced on Twitter. "I want to thank the people of Baltimore for their patience." She added that she wanted to "not have the curfew in place a single day longer than was necessary."

Rawlings-Blake's announcement comes a day after a "victory rally" in Baltimore on Saturday celebrating the charges brought against the six police officers involved in Gray's death. Though Saturday's events were mostly peaceful, 20 people were arrested during Saturday night's protests. Meghan DeMaria

The Italian Coast Guard announced Sunday that it performed a number of rescue efforts off Libya's coast on Saturday.

The Coast Guard saved 3,690 migrants from smugglers' boats. The smugglers had attempted to move the migrants from Africa on motorized rubber dinghies and fishing boats.

Italy brought some of the migrants to Sicilian ports on Sunday, and others are being taken to temporary shelters in Calabria, where they are expected to arrive on Monday. Italy's Coast Guard also announced Sunday that it had recovered 10 bodies off Libya's coast, which were found in three different rescue efforts. Meghan DeMaria

The civilian death toll in the Syrian province of Aleppo has risen to 52, including seven children.

The British-based Observatory for Human Rights announced the figures on Saturday, saying a U.S. air raid on Friday had accidentally struck civilians in a village on the eastern bank of the Euphrates River. According to the Observatory's report, the attack killed members of at least six families.

Rami Abdulrahman, who runs the observatory, told Reuters that Friday's death toll marks the highest civilian loss from a single attack by U.S. and Arab forces since they began air strikes against Islamic militant groups, including ISIS, in Syria. Reuters notes that before Friday's attack, U.S.-led strikes had killed at least 66 Syrian civilians since Sept. 23. The new attack brings the civilian death toll to at least 118. The U.S. military did not confirm the Observatory's report but said it would look into the situation. Meghan DeMaria

"I thought I won the fight," Manny Pacquiao said after the match. According to Pacquiao, Mayweather was "moving around" during the fight, and "he didn't do nothing."

"I thought I caught him many more times than he caught me," Pacquiao said of Mayweather. "I was never hurt. I was very surprised at the scores. I hit him more times than he hit me."

Mayweather, meanwhile, called Pacquiao a "hell of a fighter." "I tip my hat off to Manny Pacquiao, now I see why he's one of the guys that's at the pinnacle in the sport of boxing," Mayweather said. Meghan DeMaria

Pre-race favorite American Pharoah proved a safe choice on Saturday night at Churchill Downs in Louisville, winning the 141st Kentucky Derby in impressive, down-to-the-wire fashion. Dortmund finished second, followed by Firing Line and Carpe Diem, Sports Illustrated reports.

American Pharoah was guided by jockey Victor Espinoza, who also won the Derby last year, atop California Chrome. Next up is the Preakness Stakes on May 16, the second stop in the quest for a Triple Crown, which was last won by Affirmed in 1978. Sarah Eberspacher
