“Microwave-iIduced Modulation of Intracellular Distribution of Peptides Based on Mitochondrial Targeting Sequences,” Scientific Reports, June 11, 2026. “To the best of our knowledge, this study is the first to demonstrate the potential of MWs for delivering peptides conjugated with a signal sequence to the mitochondrial region.” ... “The precise mechanisms underlying these effects remain unclear.” From Japan.

The Japanese team working on a partial repeat of the NTP RF–animal cancer study has reported seeing no “reproducible” effects on cancer or genotoxicity in RF-exposed male rats.

The project —nicknamed NTP Lite— is a scaled-down version of the $30+ million project carried out by the U.S. National Toxicology Program which found “clear evidence” that RF radiation can cause cancer in rats.

The Japanese results were published in the journal Toxicological Sciences yesterday, January 12. The paper is open access. 

The Japanese group running a partial repeat of the NTP RF cancer study has not observed genotoxic effects among male rats exposed to 900 MHz CDMA radiation at 4 W/Kg, according to a paper to be presented tomorrow at the annual meeting of the Society of Toxicology in Salt Lake City, UT (SOT2024).

The analysis of the cancer data is ongoing and will not be reported.

On November 23, 2002, Elisabete Weiderpass, the Director of the International Agency for Research on Cancer (IARC), revealed that a new assessment of the evidence linking radiofrequency (RF) radiation to cancer would likely take place in early 2024. A formal decision could come within a few months.

Calls for a new IARC evaluation have been mounting for some years following the release of two large animal studies showing elevated tumor counts after lifelong exposure to RF radiation.

An international briefing on RF health research, known as GLORE 2020, was held online, November 9-12, featuring updates on the second phase of the U.S. National Toxicology Program (NTP) project and the Japanese-Korean partial repeat. The WHO presented a status report on ten ongoing systematic reviews of RF health effects.

Government and industry representatives from Australia, Canada, France, Japan, Korea, New Zealand and the U.S. participated, as did an assortment of academics. The public was not invited.

Everything about GLORE 2020 is being kept secret.

The Japanese Ministry of Internal Affairs and Communications is circulating a report on the partial replication of the U.S. National Toxicology Program’s RF–animal study, planned by Korean and Japanese officials. It includes the proposed candidates for the project’s International Steering Committee. 

They are:
• Alexander Lerchl, Jacobs University, Germany

Some news notes on the Interphone study:

• Those who say there are no long-term cell phone risks often point to the Interphone study from Japan, published earlier this year, for support. As we have previously reported, the Japanese researchers said there was no association between cell phones and brain tumors, even though they found a close to sixfold increase in glioma among heavily-exposed users after ten or more years (see our February 15 post). That link was based on a small number of cases and was not statistically significant; the Japanese attributed the increase to recall bias. Bruce Hocking, an occupational and environmental health physician in Melbourne, Australia, suggests otherwise. In a letter published this week in the British Journal of Cancer, Hocking points out that the risk of meningioma (another type of brain tumor) is hardly raised at all (OR=1.14). He writes: "If recall bias is the true explanation for the increased risk of glioma, it should similarly have affected the meningioma group, but it has not. Therefore, the increased risk in the glioma group may be a true finding."

Japanese researchers do not see an increase in acoustic neuroma among users of mobile phones. In a paper appearing in the December issue of Occupational and Environmental Medicine, a team led by Naohito Yamaguchi of the Tokyo Women's Medical University reports that the "risk of acoustic neuroma did not increase with the duration of mobile phone use, nor with the total call time."
