Sex is supposed to be simple, at least at the molecular level. X + X = female and X + Y = male.

But as science looks more closely, it becomes increasingly clear that a pair of chromosomes is not always sufficient to distinguish girl/boy—either from the standpoint of sex (biological traits) or of gender (social identity).

In the cultural realm, this shift in perspective has received a wide embrace, with “nonbinary” definitions of gender—transfeminine, genderqueer—having already entered the vernacular. Less visible are the changes taking place in the biological sciences.

Aril Fools' Day is an annual celebration commemorated on April 1 by playing practical jokes and spreading hoaxes. Here are three of the best of all time.

The Japanese city of Osaka has been selected to host the World Expo in 2025, an event expected to draw millions of visitors and showcase the local economy and culture. The theme for the 2025 World Expo is finding solutions to challenges facing humanity.

Harajuku has become a catwalk for jendaresu-kei (or "genderless style"). Although women who dress in a more stereotypically masculine way may also identify as "genderless," in Japan, the term jendaresu-kei refers to males who are not interested in the typical male dress code of dark suits and dress shoes.

Matching colorfully patterned fabrics and fingernails with "kawaii" (cute) hats and purses, they signal a vibrant new masculine style. But they may also represent wider changes in the way male roles are perceived in Japanese society. 

What if you could live longer just by doing more of what you love to do most?

It's an attractive theory that finds its evidence in Ogimi, a community on the island of Okinawa that's nicknamed the Village of Longevity because its residents have the highest life expectancy in the world. They also largely share a devotion to a Japanese philosophy known as ikigai, a concept that is, at times, used synonymously with purpose, passion, meaning, mission, vocation and drive.

A small cylinder called Le Grand K has defined the kilogram for more than a hundred years.

Le Grand K was forged in 1879 and is held in a locked vault outside Paris—revered and kept under lock and key because its mass, a little over 2 pounds, is the official definition of the kilogram.

If Le Grand K gets heavier or lighter—or absorbs atoms of something from the air—the definition of the kilogram literally changes.

The minister in charge of cybersecurity said he doesn't use computers.

Yoshitaka Sakurada, who just last week was criticized for stumbling over basic questions during Diet deliberations, found himself once again in hot water Wednesday after making it known that he doesn't use computers even though he is a deputy head of the government panel on cybersecurity and is tasked with overseeing policies on such matters.

Think about what you look for when you’re deciding on the perfect travel destination. Is it rich history? Cultural experiences? Lots of delicious food or shopping opportunities? Comfortable and unique places to stay? Or, perhaps, you just want to go somewhere with truly breathtaking views that you can’t get anywhere else in the world.

Guess what? You can find all of this and more in Japan.

The internet today isn’t what Tim Berners-Lee pictured when he invented the World Wide Web nearly three decades ago.

Berners-Lee says the web is “at a tipping point” as it faces threats like market concentration, data breaches, user frustration with ads and privacy, hate speech and so-called “fake news.”

“If you’d asked me 10 years ago, I would have said humanity is going to do a good job with this,” he said. “If we connect all these people together, they are such wonderful people they will get along. I was wrong.”

Japan's Cabinet has approved a draft bill that would allow the entry of more foreign blue-collar workers as the country's rapidly aging population faces labor shortages.

The bill is a major revision of Japan's policy on foreign labor. The country has long resisted accepting foreign workers, except for doctors, teachers and others in highly skilled fields. The proposed legislation would create two new visa categories for foreigners employed in more than a dozen sectors facing labor shortages, such as nursing, farming, construction and services.

An attendant at a popular garden in the heart of Tokyo has cost the facility millions of yen because he was “too frightened” to ask foreign visitors to pay the admission fee.

Every aging society faces distinct challenges. But Japan has been dealing with one it didn’t foresee: senior crime. Complaints and arrests involving elderly people, and women in particular, are taking place at rates above those of any other demographic group. Almost 1 in 5 women in Japanese prisons is a senior. Their crimes are usually minor, with 9 in 10 senior women being convicted of shoplifting.

A European-Japanese spacecraft set off on a treacherous seven-year journey to Mercury to probe the solar system's smallest and least-explored planet.

The BepiColombo mission, only the third ever to visit Mercury, blasted off from Europe’s spaceport in French Guiana aboard an Ariane 5 rocket at 10:45 p.m. local time on Friday, October 19 (0145 GMT on Saturday), according to the Japan Aerospace Exploration Agency (JAXA).

In the US, the widespread belief that the poor are simply lazy has led many states to impose work requirements on aid recipients—even those who have been medically classified as disabled. Limiting aid programs in this way has been shown to shorten recipients’ lives, creating a difference of more than 20 years in life expectancy between the rich and the poor.

A key part of the Japanese Aesthetic—the ancient ideals that still govern the norms on taste and beauty in Japan—wabi-sabi is not only untranslatable, but also considered undefinable in Japanese culture. It encapsulates a more relaxed acceptance of transience, nature and melancholy, favouring the imperfect and incomplete in everything, from architecture to pottery to flower arranging.

The British government has joined press freedom advocates and journalists in expressing dismay and disgust with Donald Trump's remarks at a rally, where he praised the unprovoked assault on a Guardian US journalist by the state's congressman, Greg Gianforte.

Trump fondly reminisced about the physical assault that occurred on 24 May 2017 when Jacobs, the Guardian's political correspondent, asked Gianforte a question about healthcare policy in the course of a special congressional election in Montana.

Nagoya-based husband-and-wife vlogging duo Rachel and Jun Yoshizuki run the YouTube channel Rachel and Jun. Their on-the-ground accounts of daily life in Japan have been viewed more than 200 million times.

There are few technologies being more rapidly adopted and expanded in 2018 than voice A.I. In just a few years, the use of voice systems has evolved from simple voice commands to entire ecosystems of applications and interactions.

Imagine the impact individual organizations could make if they teamed up to solve the world's most intractable societal problems.

That new mindset took center stage in Copenhagen at the inaugural global innovation lab, UNLEASH. There, a thousand carefully chosen, young social entrepreneurs came together from across the world to develop innovative approaches to the United Nations Sustainable Development Goals. 

Japan landed two unmanned rovers on a 1-kilometer-wide asteroid named Ryugu in late September, 2018. It was the first time robot rovers have successfully landed on an asteroid surface.

"I felt awed by what we had achieved in Japan. This is just a real charm of deep space exploration," Takashi Kubota, a spokesman for the space agency, told CNN. The two rovers together are called MINERVA-II1 and came from the spacecraft Hayabusa2.
