Soybean-rich onigiri a 'food of the future' at Osaka Expo
The food of the future? Genetically modified crops, lab-grown meat or nutrient supplements might come to mind.
But at the Osaka-Kansai Expo, one exhibitor on Aug. 4 will serve visitors what it calls the onigiri of the future, saying traditional foods are time-tested, healthy and sustainable.
'Traditional ingredients like beans and whole grains, which have long been part of Japanese diets, can also be foods of the future,' said a representative of the company, Maruyanagi Foods Inc.
The Kobe-based company's efforts are part of an exhibition around the food culture of the future.
The rice balls feature steamed soybeans blended with white rice and fiber-rich barley. They are seasoned with salt, soy sauce and traditional dashi broth.
While the food industry is increasingly driven by technology and innovation, Maruyanagi Foods is turning to Japan's culinary roots to address modern challenges.
For example, the onigiri addresses the global protein crisis, the lack of access to protein-rich food in some countries because of poverty or agricultural limitations. This is a growing concern as the world population increases and protein sources struggle to keep up.
Steamed soybeans provide 16.6 grams of protein per 100 grams, making them nearly as rich in protein as beef.
In addition, soybean production is gentler on water resources—it uses less than 13 percent of the water needed to raise an equivalent mass of beef—and it emits just a fraction of the greenhouse gas: less than 1.2 percent of cattle emissions.
There is support for this view from environmentalists. The World Wide Fund for Nature has recognized soybeans as one of its 50 foods of the future.
The new onigiri also addresses the lack of dietary fiber in today's diets.
Thanks to the inclusion of barley, which contains more fiber than white rice, each 120-gram onigiri contains 5.6 grams of dietary fiber—three times that of a conventional rice ball.
Approximately 40 percent of the new onigiri is composed of barley and steamed soybeans.
Moreover, barley can be cultivated from autumn to early summer and used in crop rotation with rice, while requiring less water and labor.
The 'Onigiri of the Future' will be showcased on Aug. 4 at the Osaka Healthcare Pavilion's Food and Culture of the Future section, with 2,800 free samples served to visitors from 10 a.m.

The Osaka subway system and Dracula want to teach you about blood
By SoraNews24 Sysmex is a company that specializes in blood testing equipment, including machines that can automatically count blood cells and technology to help in the early detection of diseases. While this has helped improve and save countless lives in the over 190 countries they've operated in for over half a century, most people probably don't even know their name. ▼ They're also strong supporters of workplace diversity, with nearly half their staff vampires. Not only that, but when you think about it, how much do you even know about your own blood? We know it's red, but we remember hearing that the plasma is yellowish, so maybe it's more of an orange or vermilion. Sounds like we need to take a ride on the Osaka Metro subway system's Midosuji Line, because from August 3-23, they'll be hanging posters with a variety of blood-related trivia. Blood Donation Day is on August 21 in Japan, which is probably why they chose this period. Posters both hanging on the walls and from the ceilings of train cars will teach of a variety of fun facts, such as: '90 percent of gorillas have B type blood.' Another good one is that if you take all the blood vessels in your body and lay them end to end, they'd be long enough to go around the Earth two and a half times. That's mainly because our bodies have millions of tiny capillaries that reach almost every cell in them. In fact, the reason our lips are red is that all the capillaries can be seen there. I didn't know any of that. I just read it in these posters. Other facts include that it takes about 30 seconds for blood to do a lap of the human body, sharks can smell a drop of blood from hundreds of meters away, crocodile blood has amazing antibacterial and antiviral properties, and freshwater eel blood is very poisonous to humans unless cooked, which is why unagi is never eaten raw as sashimi in Japan. There are other posters as well, such as ones that talk about the concepts Sysmex has on display at the 2025 Osaka-Kansai Expo. These are kind of fantastical brainstorming ideas that aren't actually in development, such as a dome where you can just chill out inside and be at one with your dreams for your mental health. You're also sure to see pictures featuring this gentleman. He's Dracula, the Sysmex mascot. As you can see, he's lost a lot of his usual sex appeal and is more of a Bill Nye the Dracula Guy this time around, but that's fitting for a blood analysis company. Sysmex hopes this will spark interest and discussions about the blood that flows through us and other creatures on this planet. So, check them out while they're hanging and take the opportunity to thank your blood for doing, um… Source, images: PR Times Read more stories from SoraNews24. -- Unko Museum to open in Okinawa with some exclusive crap -- Study of blood tests in Tokyo finds 98% as having vitamin D deficiencies -- Want to read manga and eat ice cream for free?

No blood will be shown though, if you're squeamish about that stuff.

I know it's red, but I remember hearing that the plasma is yellowish, so maybe it's more of an orange or vermilion. I also know that both Predators and the xenomorphs in the Alien movies have bright green blood, but only the xenomorphs' is highly corrosive. Sounds like I need to take a ride on the Osaka Metro subway system's Midosuji Line, because from 3 to 23 August, they'll be hanging posters with a variety of blood-related trivia.

Spacex Delivers Four Astronauts to the International Space Station Just 15 Hours after Launch
CAPE CANAVERAL, Fla. (AP) — SpaceX delivered a fresh crew to the International Space Station on Saturday, making the trip in a quick 15 hours. The four U.S., Russian and Japanese astronauts pulled up in their SpaceX capsule after launching from NASA's Kennedy Space Center. They will spend at least six months at the orbiting lab, swapping places with colleagues up there since March. SpaceX will bring those four back as early as Wednesday. Moving in are NASA's Zena Cardman and Mike Fincke, Japan's Kimiya Yui and Russia's Oleg Platonov — each of whom had been originally assigned to other missions. 'Hello, space station!' Fincke radioed as soon as the capsule docked high above the South Pacific. Cardman and another astronaut were pulled from a SpaceX flight last year to make room for NASA's two stuck astronauts, Boeing Starliner test pilots Butch Wilmore and Suni Williams, whose space station stay went from one week to more than nine months. Fincke and Yui had been training for the next Starliner mission. But with Starliner grounded by thruster and other problems until 2026, the two switched to SpaceX. Platonov was bumped from the Soyuz launch lineup a couple of years ago because of an undisclosed illness. Their arrival temporarily puts the space station population at 11. 'It was such an unbelievably beautiful sight to see the space station come into our view for the first time,' Cardman said once on board. While their taxi flight was speedy by U.S. standards, the Russians hold the record for the fastest trip to the space station — a lightning-fast three hours.
