Live rhino horns injected with radioactive material in project aimed at curbing poaching in South Africa
South African scientists on Tuesday injected radioactive material into live rhino horns to make them easier to detect at border posts in a pioneering project aimed at curbing poaching.
The country is home to a large majority of the world’s rhinos and as such is a hot spot for poaching driven by demand from Asia, where horns are used in traditional medicine for their supposed therapeutic effect.
At the Limpopo rhino orphanage in the Waterberg area, in the country’s northeast, a few of the thick-skinned herbivores grazed in the low savannah.
James Larkin, director of the University of the Witwatersrand’s radiation and health physics unit who spearheaded the initiative, told AFP he had put “two tiny little radioactive chips in the horn” as he administered the radioisotopes on one of the large animals’ horns.
The radioactive material would “render the horn useless… essentially poisonous for human consumption,” added Nithaya Chetty, professor and dean of science at the same university.
The dusty rhino, put to sleep and crouched on the ground, did not feel any pain, Larkin said, adding that the radioactive material’s dose was so low it would not impact the animal’s health or the environment in any way.
In February the environment ministry said that, despite government efforts to tackle the illicit trade, 499 of the giant mammals were killed in 2023, mostly in state-run parks. That represents an 11% increase over the 2022 figures.
Twenty live rhinos in total are to be part of the pilot “Rhisotope” project, whereby they would be administered a dose “strong enough to set off detectors that are installed globally” at international border posts that were originally installed to thwart nuclear terrorism, Larkin said.
Border agents often have handheld radiation detectors that can pick up contraband, in addition to thousands of radiation detectors installed at ports and airports, the scientists said.
“Best idea I’ve ever heard”
According to Arrie Van Deventer, the orphanage’s founder, efforts including dehorning rhinos and poisoning the horns have failed to deter poachers.
“Maybe this is the thing that will stop poaching,” the conservationist said. “This is the best idea I’ve ever heard.”
Wildebeest, warthogs and giraffe roamed the vast conservation area as more than a dozen team members performed the delicate process on another rhino.
Larkin meticulously drilled a small hole into the horn and then hammered in the radioisotope.
About 15,000 rhinos live in South Africa, according to an estimate by the international Rhino foundation.
The last phase of the project will ensure the animals’ aftercare, following “proper scientific protocol and ethical protocol,” said the project’s COO, Jessica Babich. The team will take follow-up blood samples to ensure the rhinos were effectively protected.
The material should last five years in the horns, which Larkin said was a cheaper method than dehorning the animals every 18 months when their horns grow back.
Why are rhino horns poached?
High demand for rhino horns has fueled an illegal market. In parts of Asia, the horns are thought to have unproven, powerful medicinal properties and at one point they were more expensive than cocaine in Vietnam.
Even though the horns grow back, poachers kill rhinos instead of sedating them to cut off the horns. In response, several initiatives have been launched to thwart poachers, including moving rhinos to different parts of Africa to get them out of poachers’ reach and also safely removing rhinos’ horns so they’re not targeted.
During the coronavirus pandemic, rhino poaching surged across Africa as a lack of funding caused security shortages in conservation areas.
Earlier this month, authorities in Indonesia announced six poaching suspects were arrested, accused of being part of a network that used homemade firearms to kill more than two dozen critically endangered Javan rhinos since 2018 to get their horns.
Last year, a Malaysian man known as the “Godfather” who sold a dozen black rhino and white rhino horns to a confidential source was sentenced to a year and a half in a U.S. prison.

California Gov. Newsom defers clemency decision as incoming LA County district attorney reviews Menendez brothers case
California Gov. Gavin Newsom will defer his decision on the Menendez brothers’ clemency petition to allow for incoming Los Angeles County District Attorney Nathan Hochman to review the case, his office announced Monday.
“The Governor respects the role of the District Attorney in ensuring justice is served and recognizes that voters have entrusted District Attorney-elect Hochman to carry out this responsibility,” Newsom’s office said in a statement. “The Governor will defer to the DA-elect’s review and analysis of the Menendez case prior to making any clemency decisions.”
Lyle and Erik Menendez have spent roughly 35 years in state prison after they were convicted in their parents’ 1989 murder. Outgoing District Attorney George Gascón sent letters in support of the brothers’ clemency to Newsom after a Netflix show and documentary revived interest in the brothers’ case.
“I strongly support clemency for Erik and Lyle Menendez, who are currently serving sentences of life without possibility of parole. They have respectively served 34 years and have continued their educations and worked to create new programs to support the rehabilitation of fellow inmates,” Gascón said in a statement before losing his re-election bid.
In an interview, Hochman said if the case is not resolved by a Nov. 25 habeas petition hearing — when a judge will hear a motion requesting to vacate the first-degree murder convictions — he will review the case to determine whether or not to recommend resentencing.
Hochman, who will be sworn in on Dec. 2, indicated that he would petition the court for additional time to review the cast ahead of the resentencing hearing scheduled for Dec. 11.
“I wouldn’t engage in delay for delay’s sake because this case is too important to the Menendez brothers,” Hochman said in an interview earlier in November. “It’s too important to the victims’ family members. It’s too important to the public to delay more than necessary to do the review that people should expect from a district attorney.”
Such an analysis of the case would involve reviewing thousands of pages of prison files and transcripts of the months-long trials as well as speaking with law enforcement, prosecutors, defense counsel and victims’ family members, he added.
“Whatever position I ultimately end up taking, people should expect that I spent a long time thinking about it, analyzing the evidence,” Hochman said. “But my 34 years of criminal justice experience — involving hundreds of cases as a prosecutor and a defense attorney — allow me to work quickly and expeditiously in conducting this type of thorough review because I’ve done it in many, many cases before.”
After being arrested for their parents’ deaths in 1990, the Menendez brothers went through two trials where prosecutors argued that they murdered their parents because of greed. However, the siblings testified that they killed their parents in self-defense. The brothers told the jury about the alleged sexual abuse they said they experienced at the hands of their father during an emotional, highly publicized first trial.
Following closing arguments, the jurors spent roughly four days deliberating but failed to come to a unanimous decision. The judge declared a mistrial after the jury was unable to deliver a decision.
In the next and final trial, the presiding judge did not allow the defense to submit some evidence connected to the sexual abuse allegations. Prosecutors argued the brothers were lying about the allegations.
The second jury convicted Erik and Lyle Menendez of first-degree murder in 1995 and sentenced them to life in prison without the possibility of parole.

Wyoming abortion laws, including ban on pills to end pregnancy, struck down by state judge
A state judge on Monday struck down Wyoming’s overall ban on abortion and its first-in-the-nation explicit prohibition on the use of medication to end pregnancy in line with voters in yet more states voicing support for abortion rights.
Since 2022, Teton County District Judge Melissa Owens has ruled consistently three times to block the laws while they were disputed in court.
The decision marks another victory for abortion rights advocates after voters in seven states passed measures in support of access.
One Wyoming law that Owens said violated women’s rights under the state constitution bans abortion except to protect a pregnant woman’s life or in cases involving rape and incest. The other made Wyoming the only state to explicitly ban abortion pills, though other states have instituted de facto bans on the medication by broadly prohibiting abortion.
The laws were challenged by four women, including two obstetricians, and two nonprofit organizations. One of the groups, Wellspring Health Access, opened as the state’s first full-service abortion clinic in years in April 2023 following an arson attack in 2022.
“This is a wonderful day for the citizens of Wyoming — and women everywhere who should have control over their own bodies,” Wellspring Health Access President Julie Burkhart said in a statement.
The recent elections saw voters in Missouri clear the way to undo one of the nation’s most restrictive abortion bans in a series of victories for abortion rights advocates. Florida, Nebraska and South Dakota, meanwhile, defeated similar constitutional amendments, leaving bans in place.
Abortion rights amendments also passed in Arizona, Colorado, Maryland and Montana. Nevada voters also approved an amendment in support of abortion rights, but they’ll need to pass it again it 2026 for it to take effect. Another that bans discrimination on the basis of “pregnancy outcomes” prevailed in New York.
The abortion landscape underwent a seismic shift in 2022 when the U.S. Supreme Court overturned Roe v. Wade, a ruling that ended a nationwide right to abortion and cleared the way for bans to take effect in most Republican-controlled states.
Currently, 13 states are enforcing bans on abortion at all stages of pregnancy, with limited exceptions, and four have bans that kick in at or about six weeks into pregnancy — often before women realize they’re pregnant.
Nearly every ban has been challenged with a lawsuit. Courts have blocked enforcement of some restrictions, including bans throughout pregnancy in Utah and Wyoming. Judges struck down bans in Georgia and North Dakota in September 2024. Georgia’s Supreme Court ruled the next month that the ban there can be enforced while it considers the case.
In the Wyoming case, the women and nonprofits who challenged the laws argued that the bans stood to harm their health, well-being and livelihoods, claims disputed by attorneys for the state. They also argued the bans violated a 2012 state constitutional amendment saying competent Wyoming residents have a right to make their own health care decisions.
As she had done with previous rulings, Owens found merit in both arguments. The abortion bans “will undermine the integrity of the medical profession by hamstringing the ability of physicians to provide evidence-based medicine to their patients,” Owens ruled.
The abortion laws impede the fundamental right of women to make health care decisions for an entire class of people — those who are pregnant — in violation of the constitutional amendment, Owens ruled.
Wyoming voters approved the amendment amid fears of government overreach following approval of the federal Affordable Care Act and its initial requirements for people to have health insurance.
Attorneys for the state argued that health care, under the amendment, didn’t include abortion. Republican Gov. Mark Gordon, whose administration has defended the laws passed in 2022 and 2023, did not immediately return an email message Monday seeking comment.
Both sides wanted Owens to rule on the lawsuit challenging the abortion bans rather than allow it to go to trial in the spring. A three-day bench trial before Owens was previously set, but won’t be necessary with this ruling.
