電気を通すプラスチックを開発し、2000年にノーベル化学賞を受賞した白川英樹(しらかわ・ひでき)筑波大名誉教授が8月24日、転移性肝腫瘍と原発不明がんのため、横浜市内の病院で死去した。90歳だった。東京都出身。葬儀は近親者で済ませた。喪主は妻知預子(ちよこ)さん。

【写真特集】日本のノーベル賞受賞者

1961年、東京工業大(現東京科学大)理工学部卒。同大助手を経て、76年に米ペンシルベニア大研究員、79年に筑波大助教授、82年に同大教授となり、00年に定年退官した。

プラスチックなどの高分子(ポリマー)は、電気を通さないと考えられてきた。白川さんは東工大助手時代、研究生がポリアセチレンの合成に失敗し、偶然できた薄い膜に着目。詳しく分析し、アルミ箔(はく)のような光沢を持つ薄膜を作った。

当初は注目されなかったが、米国に留学中、後にノーベル賞を共同受賞する研究者らと電気を通すポリアセチレンの薄膜開発に成功。77年に発表し、高い評価を受けた。

白川さんのポリアセチレン薄膜は、携帯電話などのモバイル機器が爆発的に普及するきっかけとなったリチウムイオン電池の開発段階で、電極の素材として注目された。ポリアセチレンなどの導電性高分子は、タッチパネルなどIT機器に広く利用されている。

Examining the influence of LLM hallucination on doctors' diagnoses, 44% misdiagnosed in an experiment presenting fictitious disease names

Researchers affiliated with French university hospitals examined the impact of the fictitious disease name ``neurocademia'' presented by LLM on doctors' diagnoses. They tested 41 doctors, and 44% included the fictitious disease name in their differential diagnosis list. Less experienced doctors were more likely to be fooled, and LLM support improved overall diagnostic accuracy from 52% to 61%, but the impact of misinformation depended on experience.

Ancient Japan's resource concentration structure revealed by volumetric analysis of ancient tombs

A preprint paper by Associate Professor Hayashi Watanabe of Seijo University suggests that the volume distribution of ancient tombs follows Zipf's law, just like the sales of modern companies. This suggests that even in ancient Japan, before the establishment of writing and a monetary economy, there was a structure in which resources were concentrated at higher levels. An even stronger concentration was observed in the Kinki region and the Sanyo region, including Kibi, and a pattern similar to that of regulated industries was confirmed.

Experts analyze the characteristics of the shaking of the Kumamoto earthquake and the differences in building damage

A maximum seismic intensity of 7 was observed during the Kumamoto earthquake, with long-period ground motion shaking seismic isolation facilities in Yatsushiro City, and short-period shaking causing damage to wooden houses around Hikawa Town. Professor Yoshiki of Tokyo University of Science pointed out that damage caused by fault slippage was also confirmed, and that buildings with seismic isolation structures were able to continue operations. The Ministry of Land, Infrastructure, Transport and Tourism has set up a committee of experts and is considering countermeasures.

Long-term evaluation of active faults in the Kinki region released; probability of an earthquake of magnitude 6.8 or greater occurring within the next 30 years is estimated at 50–60%.

Long-term evaluation of active faults in the Kinki region released; probability of an earthquake of magnitude 6.8 or greater occurring within the next 30 years is estimated at 50–60%.

On the 28th, the Earthquake Research Committee of the government's Earthquake Research Promotion Headquarters released a long-term assessment of a total of 45 active faults in the Kinki region and 11 surrounding prefectures, estimating the probability of an earthquake of magnitude 6.8 or higher occurring within the next 30 years to be 50-60%. By region, 30% are in the northwestern Kinki region, 40-60% in the Kinki Triangle, and 7% in the Kii Peninsula. The maximum magnitude is expected to be around M8.1-8.3 due to simultaneous activity in three sections of the Yanagase-Sekigahara fault zone. Part of the Rokko-Awajishima fault zone was reevaluated and raised from A to S, while the Kamimachi fault zone was lowered from S to Z.
