Japan culled 1,381,700 deer and wild boar in fiscal 2024, and 5.6 percent of that mass became meat. The rest goes to a hole in the ground or an incinerator, and the capacity is not there. Scotland does it differently.
Yamanashi and Riken researchers cut out the whole Y chromosome to make female clones of male mice. Read next to the same university's finding that cloning dies at 58 generations, and Osaka's eggs from male cells.
A 10 mm jellyfish rewound itself ten times in two years. A genome paper on about 1,000 genes cast it as nature's Yamanaka reprogramming; a US researcher attacked that premise with Japanese data it never cited.
Japan's NIES has made iPS cells from four endangered birds. The flightless Okinawa rail has lost one of the two genes birds use to spot a virus. Inside the minus-160°C cell bank and the brain organoids grown from it.
Rausu, Rishiri, hosome, ma-kombu: four kelps sold under four names and four price tiers. A Hokkaido University team read the DNA of 475 plants and found no genetic line between them.
Fish have no eyelids, yet pufferfish close their eyes. Shimonoseki's Kaikyokan aquarium dissected 51 species and traced the eye-closing muscle to the one that deflates a puffed-up puffer.
Warming seas pushed a pufferfish north across the Tsugaru Strait, and the hybrids do not fit Japan's 1983 table of edible species and parts. How the rulebook caught up, and why the Mediterranean has the same gap.
Murakami's salmon run fell from 55,000 fish to 1,400 in a decade. Now the town is spending about $32,000 to attempt what Norway and Chile have not: closing the life cycle of chum salmon entirely on land.
A paint maker in Imabari spent five years building a bear deterrent launcher called Kintaro. Its president fired it at his own body for a year and a half, and zoos refused to let him test it on a real bear.
A kawakawa hybrid made bluefin tuna sperm at eight months, and rainbow trout now spawn Chinook salmon yearly. Inside Japan's 20-year surrogate broodstock effort and Kindai's 32-year tuna project.
That blank, open-mouthed face your cat makes after a sniff may finally have an explanation: 13 branched-chain fatty acids in urine, blended to a ratio unique to each cat and stockpiled in the kidney.
