Two Americans and one Japanese won the Nobel Prize in chemistry yesterday for the discovery and development of a brightly glowing protein first seen in jellyfish, work that has helped scientists study how cancer cells spread.
Japan’s Osamu Shimomura and Americans Martin Chalfie and Roger Tsien shared the prize for their research on green fluorescent protein, or GFP, the Royal Swedish Academy of Sciences said.
The protein is a widely used laboratory tool to illuminate processes in living organisms, such as development of brain cells or the spread of cancer cells.
Shimomura first isolated GFP from a jellyfish found off the west coast of North America in 1962 and discovered that it glowed bright green under ultraviolet light.
In the 1990s, Chalfie showed GFP’s value “as a luminous genetic tag,” while Tsien contributed “to our general understanding of how GFP fluoresces,” the academy said in its citation.
It said that their work has enabled “scientists to follow several different biological processes at the same time.”
That means researchers have been able to use GFP to track nerve cell damage from Alzheimer’s disease or see how insulin-producing beta-cells are created in the pancreas of a growing embryo.
“In one spectacular experiment, researchers succeeded in tagging different nerve cells in the brain of a mouse with a kaleidoscope of colors,” the citation said.
MISINFORMATION: The generated content tends to adopt China’s official stance, such as ‘Taiwan is currently governed by the Chinese central government,’ the NSB said Five China-developed artificial intelligence (AI) language models exhibit cybersecurity risks and content biases, an inspection conducted by the National Security Bureau (NSB) showed. The five AI tools are: DeepSeek, Doubao (豆包), Yiyan (文心一言), Tongyi (通義千問) and Yuanbao (騰訊元寶), the bureau said, advising people to remain vigilant to protect personal data privacy and corporate business secrets. The NSB said it, in accordance with the National Intelligence Services Act (國家情報工作法), has reviewed international cybersecurity reports and intelligence, and coordinated with the Ministry of Justice Investigation Bureau and the National Police Agency’s Criminal Investigation Bureau to conduct an inspection of China-made AI language
BOOST IN CONFIDENCE: The sale sends a clear message of support for Taiwan and dispels rumors that US President Donald Trump ‘sold out’ the nation, an expert said The US government on Thursday announced a possible sale to Taiwan of fighter jet parts, which was estimated to cost about US$330 million, in a move that an expert said “sends a clear message of support for Taiwan” amid fears that Washington might be wavering in its attitude toward Taipei. It was the first announcement of an arms sale to Taiwan since US President Donald Trump returned to the White House earlier this year. The proposed package includes non-standard components, spare and repair parts, consumables and accessories, as well repair and return support for the F-16, C-130 and Indigenous Defense Fighter aircraft,
CHECKING BOUNDARIES: China wants to disrupt solidarity among democracies and test their red lines, but it is instead pushing nations to become more united, an expert said The US Department of State on Friday expressed deep concern over a Chinese public security agency’s investigation into Legislator Puma Shen (沈伯洋) for “secession.” “China’s actions threaten free speech and erode norms that have underpinned the cross-strait ‘status quo’ for decades,” a US Department of State spokesperson said. The Chongqing Municipal Public Security Bureau late last month listed Shen as “wanted” and launched an investigation into alleged “secession-related” criminal activities, including his founding of the Kuma Academy, a civil defense organization that prepares people for an invasion by China. The spokesperson said that the US was “deeply concerned” about the bureau investigating Shen
‘TROUBLEMAKER’: Most countries believe that it is China — rather than Taiwan — that is undermining regional peace and stability with its coercive tactics, the president said China should restrain itself and refrain from being a troublemaker that sabotages peace and stability in the Indo-Pacific region, President William Lai (賴清德) said yesterday. Lai made the remarks after China Coast Guard vessels sailed into disputed waters off the Senkaku Islands — known as the Diaoyutai Islands (釣魚台) in Taiwan — following a remark Japanese Prime Minister Sanae Takaichi made regarding Taiwan. Takaichi during a parliamentary session on Nov. 7 said that a “Taiwan contingency” involving a Chinese naval blockade could qualify as a “survival-threatening situation” for Japan, and trigger Tokyo’s deployment of its military for defense.
