'Forever chemicals' found in organs of vulnerable Japanese wildcats
The Ehime University-led research team found the chemicals in the organs of all 21 cats examined, raising concerns about the impact of pollution on wildlife conservation across Japan.
"For the protection of all wild animals, not just the Tsushima leopard cat, there must be a nationwide survey and investigations to identify the pollution source," said Kei Nomiyama, an associate professor at the university in western Japan.
Tsushima leopard cats inhabit the island of Tsushima in southwestern Japan's Nagasaki Prefecture, and are listed as vulnerable on the Environment Ministry's Red List of endangered species.
Their numbers have declined due to habitat loss and roadkill. The government estimates that around 100 remain, and zoos in Japan are working to breed the species.
The research team received permission from the ministry to examine the livers and kidneys of 21 dead wildcats that died between 2022 and 2025, testing for 37 PFAS chemicals.
Nearly all the cats had PFAS concentrations exceeding toxicity thresholds in liver cell tests, indicating potential risks to liver function, according to the study. Kidney concentrations were also considered high, it said.
No significant differences based on age, sex or location were recorded.
The median concentration of PFAS chemicals was eight times higher than levels found in a study of European wildcats in Germany.
Experts suspect marine debris and illegal dumping as sources of the pollution, with concentrations likely accumulating through the food chain.
The team also measured persistent organic pollutants, known as POPs, in 19 cats, with some showing extremely high levels of contamination. Nomiyama said there is a "strong possibility" the pollution is connected to the species' declining population.
PFAS is a general term for a group of over 10,000 artificial chemicals that include PFOS, or perfluorooctanesulfonic acid, and PFOA, or perfluorooctanoic acid.
Used in products such as firefighting foam and nonstick cookware coatings, PFAS are known as forever chemicals because they are highly resistant to breakdown, and accumulate in soil and water as environmental pollutants.

'Forever chemicals' found in organs of vulnerable Japanese wildcats
High concentrations of potentially carcinogenic PFAS "forever chemicals" have been found in Tsushima leopard cats -- a designated natural monument and vulnerable species native to a Japanese island -- researchers said.

OSAKA (Kyodo) -- High concentrations of potentially carcinogenic PFAS "forever chemicals" have been found in Tsushima leopard cats -- a designated natural monument and vulnerable species native to a Japanese island -- researchers said Thursday.

Europe Unveils a Deal for More Food and Fuel for Gaza. Israeli Strike Kills 15 outside a Clinic
DEIR AL-BALAH, Gaza Strip (AP) — European officials reached a new deal with Israel to allow desperately needed food and fuel into Gaza, the European Union's foreign policy chief said Thursday, hours after an Israeli airstrike killed 15 people, including 10 children, waiting for help outside a medical clinic. The children's deaths drew outrage from humanitarian groups even as Israel allowed the first delivery of fuel to Gaza in more than four months, though still less than a day's supply, according to the United Nations. 'The killing of families trying to access life-saving aid is unconscionable,' UNICEF's chief, Catherine Russell, said. 'These were mothers seeking a lifeline for their children after months of hunger and desperation.' The Israeli military said it was targeting a militant when it struck near the clinic. Security camera footage outside the clinic in the central Gaza city of Deir al Balah showed about a dozen people squatting in front of the clinic when a projectile explodes a few meters (yards) away, leaving bodies scattered. Meanwhile, Israeli Prime Minister Benjamin Netanyahu prepared to leave Washington after meetings with President Donald Trump, apparently without finalizing a temporary ceasefire advocated by the White House. A deal to increase aid The deal announced by European officials could result in 'more crossings open, aid and food trucks entering Gaza, repair of vital infrastructure and protection of aid workers,' said Kaja Kallas, the 27-member EU's top diplomat. 'We count on Israel to implement every measure agreed,' she said in a post on social media. Aid groups say Israeli military restrictions and recurring violence have made it difficult to deliver assistance in Gaza even after Israel eased its 2 1/2 month total blockade in May. Experts have warned the strip is at risk of famine, 21 months into the Israel-Hamas war. Kallas said the deal would reactivate aid corridors from Jordan and Egypt and reopen community bakeries and kitchens across Gaza. She said measures would be taken to prevent the militant Hamas group from diverting aid. Israel has long accused Hamas of stealing aid and selling it to finance militant activities. The U.N. says there is no evidence for widespread diversion. Israeli Foreign Minister Gideon Saar acknowledged the deal while at a conference in Vienna, saying it followed 'our dialogue with the EU' and that it includes 'more trucks, more crossings and more routes for the humanitarian efforts.' Neither Saar not Kallas said whether the aid would go through the U.N.-run system or an alternative, U.S.- and Israeli-backed mechanism that has been marred by violence and controversy. The U.N. said Israel had permitted a team to bring 75,000 liters of fuel into Gaza, the first delivery allowed in 130 days. U.N. spokesman Stephane Dujarric warned it wasn't enough to cover a single day's energy needs in the territory and that services would shut down without more shipments. Israeli strikes kill at least 36 Israeli strikes pounded the Gaza Strip overnight and early Thursday, killing at least 36 Palestinians, local hospitals and aid workers said. The Israeli military said one soldier was killed in Gaza. The 15 killed outside the clinic were waiting for nutritional supplements, according to Project Hope, an aid group that runs the facility. Along with the 10 children, two women were among those killed. 'No child waiting for food and medicine should face the risk of being bombed,' said Dr. Mithqal Abutaha, the group's project manager. At the morgue of Al-Aqsa Hospital, families prayed over the bodies of their loved ones, laid across the floor. Omar Meshmesh held the body of his 3-year-old niece Aya Meshmesh. 'What did she ever do? Did she throw a rocket at them or throw something at them? … she's an innocent child.' Israel's military said it struck near the clinic while targeting a militant it said had entered Israel on Oct. 7, 2023. It said it was investigating. Gaza's Nasser Hospital reported a total of 21 deaths in airstrikes in the southern town of Khan Younis and the nearby coastal area of Muwasi. It said three children and their mother, as well as two other women, were among the dead. Netanyahu leaves Washington Readying to leave Washington, Netanyahu said Israel continues to pursue a deal for a 60-day pause in the fighting and the release of half of the 50 hostages remaining in Gaza, many of them believed dead. Once that deal is in place, Israel is prepared to negotiate a permanent end to the war, Netanyahu said — but only on condition that Hamas disarms and gives up its governing and military capabilities in Gaza. If this 'is not achieved through negotiations in 60 days, we will achieve it in other ways; by using force, the force of our heroic army,' Netanyahu said in a video statement. Still, U.S. officials held out hope that restarting high-level negotiations — mediated by Egypt and Qatar and including White House envoy Steve Witkoff — could bring progress. 'We're closer than we've been in quite a while and we're hopeful, but we also recognize there's still some challenges in the way,' U.S. Secretary of State Marco Rubio told reporters during a stop in Kuala Lumpur, Malaysia. West Bank violence, another Israeli soldier killed The Israeli military said a soldier was killed in Khan Younis the day before, after militants burst out of an underground tunnel and tried to abduct him. The soldier was shot and killed, while troops in the area shot the militants, hitting several of them, it said. Eighteen soldiers have been killed in the past three weeks, one of the deadliest periods for the Israeli army in months, putting additional public pressure on Netanyahu to end the war. Meanwhile, two Palestinian attackers killed a 22-year-old Israeli man at a supermarket in a settlement in the Israeli-occupied West Bank on Thursday afternoon, according to Israel's Magen David Adom emergency services. Israeli police said two people in a stolen vehicle attacked a security guard at the supermarket. Paramedics said people on site shot and killed the two attackers. There was no information about the attackers but Israeli troops were setting up roadblocks around the Palestinian town of Halhul, around 10 kilometers (6 miles) from the supermarket. Earlier Thursday, a 55-year-old Palestinian man was killed in the West Bank, the Palestinian Health Ministry said. The Israeli military said the man was shot after stabbing a soldier in the village of Rumana. The soldier suffered moderate wounds. The war in Gaza has sparked a surge of violence in the West Bank, with the Israeli military targeting militants in large-scale operations that have killed hundreds of Palestinians and displaced tens of thousands. That has coincided with a rise in settler violence and Palestinian attacks on Israelis. Palestinian militants from the West Bank have also attacked and killed Israelis in Israel and the West Bank. The war began after Hamas attacked Israel in 2023, killing around 1,200 people and taking 251 others hostage. Most have been released in earlier ceasefires. Israel responded with an offensive that has killed more than 57,000 Palestinians, more than half of them women and children, according to Gaza's Health Ministry. The ministry, which is under Gaza's Hamas-run government, doesn't differentiate between civilians and combatants. The U.N. and other international organizations see its figures as the most reliable statistics on war casualties.
