Claims that cigarettes made from transgenic tobacco could be effective in fighting lung cancer were withdrawn yesterday as Academia Sinica retracted its previous statements under pressure from the medical community.
"There is no such thing as a healthy cigarette. While smoking does not necessarily result in lung cancer, it will affect about 80 percent of smokers. There is a general consensus on this point," National Taiwan University Hospital intern-al medicine chief Yang Pan-chyr (
"We know that cigarettes can lead to numerous diseases, not just lung cancer. Even if cigarettes could fight lung cancer, it would still lead to other conditions. There are around 4,000 chemicals in cigarettes, so how do you break [health effects] down?" said Yeh Chin-chuan (
Chen Hueih-min (
Chen had said that tobacco could possibly serve as a "factory" for the cost-effective production of the peptide.
However, Yeh pointed out that there was no scientific evidence that transgenic tobacco could be effective in fighting cancer.
"Let scientific evidence speak. If it is really possible that cigarettes could fight cancer, then people need to know. But, so far, there is no proof of that," Yeh said.
"We will pay attention to societal responses in the future. If developing transgenic tobacco will cause societal turmoil, then we will take that into consideration," Chen said. He also asked the public not to the stand in the way of biotechnological developments.
The applications of Chen's peptide will be difficult to predict, with companies possibly using the peptide to develop cancer-fighting transgenic tobacco.
"We are applying for a patent now, and afterward the peptide could see different applications. We as patent-holders probably have some say as to the applications and could block private companies from developing `healthy' cigarettes,'" Chen said.
Meanwhile, Consumers' Foundation president Tsai Chai-pen (
"If this [Chen's report] had been issued by any other agency, I would not have paid any attention. However, these claims were issued by the Academia Sinica," Tsai said.
"This could be used as a new excuse for smoking, but what about those who have to deal with second-hand smoke? Those who don't smoke should not be subjected to smoke in public areas," Tsai said.
SEND A MESSAGE: Sinking the amphibious assault ship, the lead warship of its class, is meant to show China the US Navy is capable of sinking their ships, an analyst said The US and allied navies plan to sink a 40,000-tonne ship at the latest Rim of the Pacific (RIMPAC) exercise to simulate defeating a Chinese amphibious assault on Taiwan. This year’s RIMPAC — the 29th iteration of the world’s largest naval exercise — involves the US, 28 partners, more than 25,000 personnel, 40 warships, three submarines and more than 150 aircraft operating in and around Hawaii from yesterday to Aug. 1, the US Navy said in a press release. The major components of the event include multidomain warfare exercises in multiship surface engagements, anti-submarine warfare and multi-axis defense of a carrier strike
Taiwanese could risk being extradited to China when traveling in countries with close ties to Beijing, Taiwan Association of University Professors deputy chairman Chen Li-fu (陳俐甫) said on Friday. Chen’s comments came after China on Friday last week announced new judicial guidelines targeting Taiwanese independence advocates. Myanmar, Cambodia, Laos and Djibouti are among the countries where Taiwanese could risk being extradited to China, he said. The Mainland Affairs Council (MAC) on Thursday elevated the travel alert for China, Hong Kong and Macau to “orange” after Beijing announced its guidelines to “severely punish Taiwanese independence diehards for splitting the country and inciting secession.” Extradition treaties
The airspace around Taiwan Taoyuan International Airport and Taipei International Airport (Songshan airport) is to be closed for an hour on July 25 and July 23 respectively, due to the Han Kuang military exercises, the Ministry of National Defense said yesterday. The annual exercise is to be held on Taiwan proper and its outlying islands from July 22 to 26. During last year’s exercise, the military conducted anti-aircraft landing drills at the Taoyuan airport for the first time, for which a one-hour no-fly ban was issued. Based on a live-fire bulletin sent out by the Maritime and Port Bureau, the nation’s
CROSS-BORDER CRIME: The suspects cannot be charged with cybercrime in Indonesia as their targets were in Malaysia, an Indonesian immigration director said Indonesian immigration authorities have detained 103 Taiwanese after a raid at a villa on Bali, officials said yesterday. They were accused of misusing their visas and residence permits, and are suspected of possible cybercrimes, Safar Muhammad Godam, director of immigration supervision and enforcement at the Indonesian Ministry of Law and Human Rights told reporters at a news conference. “The 103 foreign nationals stayed at the villa and conducted suspicious activities, which we suspect are activities related to cybercrime activities,” he said, presenting laptops and routers at the news conference. Godam said Indonesian authorities cannot charge them with conducting cybercrime. “During the inspection, we
