The research was described as game-changing by many experts in the field when it was published in January. However, it was subsequently investigated by the Japanese government-affiliated Riken institute, which “categorized some of the errors as misconduct,” Nature said.

The two papers, led at Riken by Haruko Obokata, 30, detailed simple ways to reprogram mature animal cells back to an embryonic-like state, allowing them to generate many different types of cells — suggesting hope for a way of replacing damaged cells or growing new organs in humans.

Whenever her dementia-afflicted husband went to bed, Reiko Ozawa would sigh in relief and sometimes wish he would never wake up.

That was because once he did, a living nightmare would await her, as her husband, Kunio, would tend to wander off, rant at her and even suffer hallucinations.

The approval rating for Prime Minister Shinzo Abe’s Cabinet was down 4.3 points in a Kyodo News poll conducted after the government decided Tuesday to allow Japan to exercise the right to collective self-defense.

In the telephone poll conducted on Tuesday and Wednesday, the approval rating stood at 47.8 percent, down from 52.1 percent in the June 21-22 survey and slipping below 50 percent for the first time since December.

The Abe administration’s reinterpretation of the war-renouncing Constitution to allow greater use of military force in defending other countries is one of the biggest changes ever to Japan’s postwar security policy.

The administration has given a range of examples as to how the Self-Defense Forces might used when related laws are updated later this year. They include scenarios in which troops might:

Life was relaxing and peaceful for Shigeru Suzuki until six years ago, when he realized that Hiroko, his wife of more than 30 years, was having problems doing simple chores.

The 77-year-old former employee of a major civil engineering firm recalls that, at first, he couldn’t understand why Hiroko couldn’t sort clothes as told. One day, he got irritated and snapped at her, pressing her to explain why she couldn’t just remember to put the clothes away. Hiroko then tearfully replied: “It’s not like I want to be forgetful.”

A 47-year-old politician quickly became an Internet phenomenon Wednesday after crying like a toddler as he tried to explain his profligate use of public funds.

Television talk shows carried looped footage of a press conference in which Ryutaro Nonomura wails and bangs his fists on the desk as tears stream down his face.

Food manufacturers are beginning to wake up to a nationwide rise in the popularity of granola, and are stepping up production of the oat-based snack in an attempt to create a new staple for Japanese breakfast tables.

“We want to entrench the popularity of granola to make it a new major revenue source,” said Akira Matsumoto, chairman and chief executive officer of major Japanese snack maker Calbee Inc.

The administration of Prime Minister Shinzo Abe on Tuesday authorized a reinterpretation of war-renouncing Article 9 of the Constitution, allowing Japan for the first time since World War II to come to the aid of an ally under attack.

The authorization marks a landmark shift in the postwar defense posture, which has prevented the country from waging wars on foreign soil.

Hong Kong police arrested more than 500 people Wednesday after tens of thousands in the former British colony joined a massive march to push for democracy.

Anger at mainland China has never been greater after Beijing warned recently it holds the ultimate authority over the freewheeling capitalist enclave despite agreeing to a Basic Law that gave the city a high degree of autonomy for 50 years after British rule ended in 1997.

Japan is at a historic crossroads in amending its long-held pacifist defense posture, a move that it may never reverse. Prime Minister Shinzo Abe’s Cabinet formally reinterpreted the war-renouncing Article 9 on Tuesday, reading the Constitution as permitting at least partial use of the right of collective self-defense.

Administration officials and New Komeito lawmakers defend the decision by saying Japan will only use the right under strict conditions.
