Research into reverse-sex genitalia deserved award
In caves in Brazil there lives a tiny insect with the most extraordinary story. It feeds on bat droppings and chews on the dead carcasses of fallen bats. When it copulates, it does so slowly — a single sexual act takes up to 70 hours, or three full days. But that's not even the oddest thing about it. In this species the female has developed a penis, and the male a vagina.

Cephalopods show signs of intelligence
Is it morally acceptable to eat intelligent animals? Everyone can make their own mind up about this. Some people think that there's nothing wrong with eating any kind of animal. For me, I drew a somewhat arbitrary zoological line in the sand and decided that any animal "above" a fish was off-limits. In other words, birds and mammals are off the menu, whereas fish and invertebrates are OK to eat.

Did DNA influence Japan's collectivist society?
If you've spent any time in Japan you will have heard the expression, "Deru kugi wa utareru" ("The nail that sticks out gets hammered down"). The phrase is used to explain how Japanese society traditionally prefers conformity and social harmony to independence and individual expression. There is a similar saying in China — "The shot hits the bird that pokes its head out" — and no doubt something equivalent in South Korea, too. East Asian countries tend to have collectivist societies, while individualism typically prevails in the West.

'Gloomy Japan' highlights a loss of hope
"In recent times, reflections on the future of Japanese society have not generally been couched in optimistic terms," says Yuji Genda, a professor of Labor Economics at the University of Tokyo's Institute of Social Science.

Waking up to the mechanics of sleep
Feeling tired? Wish you had more time in your life? Got too much to do? I answer all three questions in the affirmative, and I am far from alone — in fact, almost everyone I know feels the same. The problem may be a lack of sleep, and, counterintuitively, it may also be a lack of play. But let's start with the former.

Darwin specimens showcase evolution for first time in Tokyo exhibition
Charles Darwin certainly did not consider it a sin to kill a mockingbird. The 19th-century English biologist killed many of the birds whilst on board the HMS Beagle survey ship as he traveled around the world. The specimens are more important than you might think and you can see a number of them at "Treasures of the Natural World," a new exhibition at the National Museum of Nature and Science, Tokyo.

'Moving Zen' and the modern samurai
"Be true to the thought of the moment and avoid distraction. Other than continuing to exert yourself, enter into nothing else, but go to the extent of living single thought by single thought."

Recalling the ins and outs of our memory
In the Harry Potter films, Hogwarts headmaster Albus Dumbledore shows the young wizard memories that he keeps in glass vessels. The franchise portrays memories as things that possess a physical structure that can be moved around. Although they appear to look like wispy bits of fluff, they are given form and structure.

Manipulating the brain to hasten learning
For some athletes, success has come from a dedication to practice and the repetition of a particular routine. Baseball icon Ichiro Suzuki or English soccer star David Beckham are two examples that immediately spring to mind.

Space exploration and human evolution
Can we become a multiplanetary species? There have been several spectacular announcements along these lines recently. Both SpaceX founder Elon Musk and Amazon founder Jeff Bezos have unveiled ambitious plans and tested rockets. Now aerospace multinational Boeing has ramped up its plans to get to Mars. What we're doing is more than just becoming multiplanetary, however — we are intervening in human evolution. In short, we are accelerating our own speciation.

Did Japan fudge the truth about whaling?
If you've been following the tragic farce that is Japan's official stance on whaling, you'll know that the arguments made by the country's Institute for Cetacean Research (ICR) to try and justify the hunting of whales have been soundly rejected. Japan maintains it needs to kill whales as part of a scientific research program to learn more about whale populations and determine if larger-scale commercial whaling is sustainable. Few people really believe this and even the International Court of Justice ruled in 2014 that Japan's whaling program was not scientific. Since 2005, the judges said, some 3,600 minke whales have been killed, and just two research papers have been published.

The gene that may benefit sumo giants
Samoa, with its string of beautiful islands and coral atolls in the South Pacific, is attracting more than just tourists these days. Scientists are heading there, too. The nation holds the uneviable position of being No. 1 in the world for obesity. Among Samoan men, 80 percent are either overweight or obese, and that figure reaches 91 percent for Samoan women. They are the fattest people in the world, and they are proving revealing subjects for genetics studies.

Rethinking the age-old question of youth
Japan used to follow a wonderful practice to mark old age: Everyone who reached their 100th birthday received a silver sake cup called a sakazuki. It's certainly better than the tradition in Britain, where centenarians simply get a letter from the queen.

Saluting Shakespeare's scientific legacy
On April 23, the literary world marks the 400th anniversary of the death of William Shakespeare. It's a good excuse for a lot of fuss: Britain's Royal Mint has produced a new £2 coin, the postal service has prepared a set of commemorative stamps depicting portraits of the Bard and thousands of theaters worldwide are expected to celebrate the anniversary.

Stem cells used to replace part of the human brain
Sometimes I imagine famous scientists and doctors from the past magically catching a glimpse of our modern world. Sure it's fun to picture their gawping faces, but the daydream also helps remind me that we take so much for granted these days. And, in fact, it illustrates the incredible pace of discovery, because you don't even have to go very far back in time before you are in a completely different era.
