PM Lee arrives to a warm welcome at the White House
With a 19-gun salute and a military band playing, Prime Minister Lee Hsien Loong was welcomed to the White House by United States President Barack Obama.
The US Ceremonial Guard was in place at the South Lawn for the official arrival ceremony, along with thousands who turned up not just with miniature US and Singapore flags, but also with fans to keep themselves cool on a hot summer day in Washington, DC.
Mr Lee and his wife were greeted by Mr Obama and First Lady Michelle Obama as they stepped out of the car.
Millennials have less sex, study shows
Young people today are not having as much sex as previous generations, despite the widespread availability of dating sites and apps and more accepting attitudes about premarital sex, researchers said.
The study focused on millennials, the generation of people born in the 1990s, and found they were the most sexually inactive group since the Depression era.
"The only other generation that showed a higher rate of sexual inactivity were those born in the 1920s," said the study.
Global heat, sea level hit record highs in 2015
Global heat, greenhouse gases and sea levels all climbed to record highs last year, making 2015 the worst in modern times across a range of key environmental indicators, international scientists said.
A dire picture of the Earth's health is painted in the State of the Climate report, a peer-reviewed 300-page tome that comes out once a year and is compiled by 450 scientists from around the world.
The record heat that the planet experienced last year was driven partially by global warming, and was exacerbated by the ocean heating trend known as El Nino, it said.
Star Trek actor Anton Yelchin's parents sue carmaker over his death
The parents of late Star Trek actor Anton Yelchin have filed a lawsuit against the makers of his car after it rolled down the driveway of his home and killed him.
The Russian-born actor died instantly when his 2015 Jeep Grand Cherokee pinned him against a concrete mailbox at his house in Los Angeles on June 19, according to police.
"It is wrong, it's against nature when the parents bury (their) own child," Yelchin's father Viktor said at a news conference announcing the wrongful death lawsuit. "That's why we hope that this lawsuit will make our family never go through this same hell as we are going through right now."
