Alien implants are objects that some people who believe they were abducted by aliens say were placed in their bodies during the experience. Claims about them include tracking, mind control and the transmission of radio signals. Objects removed from claimants and analysed have turned out to be ordinary materials such as glass, metal fragments and fibres.[1][2]
History

According to Peter Rogerson, writing in Magonia magazine, the earliest known mention of an alien implant came in a March 1957 radio interview on Long John Nebel's show. Ufologist John Robinson described a neighbour's claim to have been kidnapped by aliens in 1938 and kept quiet by small earphones placed behind his ears.[1] The 1953 film Invaders from Mars had already shown aliens inserting small needles into victims' necks.[1]
Betty Andreasson of Massachusetts claimed that aliens had placed a device in her nose during an abduction in 1967, a claim publicised by Raymond Fowler in The Andreasson Affair.[1] Later writers, including Whitley Strieber, helped make implants a common feature of abduction stories.[1] Psychiatrist John E. Mack wrote that a client gave him a thin, wiry object, under an inch long, which she said had come out of her nose after an abduction.[1]
Roger Leir
The name most closely linked with alien implants is Roger Leir, a California podiatrist and foot surgeon. By his death in 2014 he claimed to have removed about 50 such objects from patients.[1][2] Leir said that the implants transmitted radio signals on what he called a "deep space frequency", which he gave as 14.749650 MHz.[2]
Skeptical analysis
Brian Dunning's Skeptoid podcast examined Leir's published evidence in 2016. Dunning noted that the frequency Leir gave lies in the ordinary high-frequency band used for aviation, shortwave and amateur radio. He pointed out that a laboratory analysis Leir presented showed only human tissue and silica glass, from an object removed from a patient's toe. Another sample was mostly nickel-iron, a material found in many industrial alloys.[2] Dunning also quoted Leir saying that a planned television series about implants had a contract specifying no skeptics or debunkers.[2]
Skeptical investigator Joe Nickell has written that supposed implants tend to be ordinary bits of glass, metal or carbon fibre, often found in the toes, hands or shins. He quoted a medical department head who said such objects are usually picked up in falls or by walking barefoot and become surrounded by scar tissue.[1] Psychologist Susan Blackmore also published an analysis of a claimed implant.[1]
