Geneva — The World Health Organization said on Tuesday it had been able to start its polio campaign in central Gaza and vaccinate tens of thousands of children despite Israeli strikes in the designated protected zone hours before. As part of an agreement between the Israeli military and Palestinian militant group Hamas, humanitarian pauses in the year-long Gaza war had been due to begin early on Monday to reach hundreds of thousands of children. However, hours before then, the U.N. humanitarian office said Israeli forces struck tents near al Aqsa hospital, inside in the zone, where it said four people were burned to death.   The U.N. Palestinian refugee agency UNRWA said one of its schools in the central Gazan city of Nuseirat, intended as a vaccination site, was hit overnight between Sunday and Monday, killing up to 22 people. WHO spokesperson Tarik Jasarevic told a Geneva press briefing that over …

CAPE CANAVERAL, Florida — A NASA spacecraft rocketed away Monday on a quest to explore Jupiter’s tantalizing moon Europa and reveal whether its vast hidden ocean might hold the keys to life. It will take Europa Clipper 5 1/2 years to reach Jupiter, where it will slip into orbit around the giant gas planet and sneak close to Europa during dozens of radiation-drenched flybys. Scientists are almost certain a deep, global ocean exists beneath Europa’s icy crust. And where there is water, there could be life, making the moon one of the most promising places out there to hunt for it. Europa Clipper won’t look for life; it has no life detectors. Instead, the spacecraft will zero in on the ingredients necessary to sustain life, searching for organic compounds and other clues as it peers beneath the ice for suitable conditions. SpaceX started Clipper on its 3 billion-kilometer (1.8 million-mile) journey, …

CAPE CANAVERAL, Fla. — A NASA spacecraft is ready to set sail for Jupiter and its moon Europa, one of the best bets for finding life beyond Earth. Europa Clipper will peer beneath the moon’s icy crust where an ocean is thought to be sloshing fairly close to the surface. It won’t search for life, but rather determine whether conditions there could support it. Another mission would be needed to flush out any microorganisms lurking there. “It’s a chance for us to explore not a world that might have been habitable billions of years ago, but a world that might be habitable today — right now,” said program scientist Curt Niebur. Its massive solar panels make Clipper the biggest craft built by NASA to investigate another planet. It will take 5 1/2 years to reach Jupiter and will sneak within 16 miles (25 kilometers) of Europa’s surface — considerably closer than …

WASHINGTON — As if the largest bug to ever live – a monster about 2.7 meters long with several dozen legs – wasn’t terrifying enough, scientists could only just imagine what the extinct beast’s head looked like. That’s because many of the fossils of these creatures are headless shells that were left behind when they molted, squirming out of their exoskeletons through the head opening as they grew ever bigger — 2.4 to 2.7 meters and more than 50 kilograms. Now, scientists have produced a mug shot after studying fossils of juveniles that were complete and very well preserved, if not quite cute. The giant bug’s topper was a round bulb with two short bell-shaped antennae, two protruding eyes like a crab, and a rather small mouth adapted for grinding leaves and bark, according to new research published Wednesday in Science Advances. Called Arthropleura, these were arthropods — the group that …

PHNOM PENH, Cambodia — Thirteen pregnant Philippine women accused of illegally acting as surrogate mothers in Cambodia after being recruited online could face prison terms after giving birth, a senior Interior Ministry official said Saturday.  Interior Ministry Secretary of State Chou Bun Eng, who leads the country’s fight against human trafficking and sexual exploitation, said police found 24 foreign women, 20 Philippine and four Vietnamese, when they raided a villa in Kandal province, near the capital of Phnom Penh, on September 23.  Thirteen of the Philippine women were found to be pregnant and were charged in court on October 1 under a provision in the law on Suppression of Human Trafficking and Sexual Exploitation, she said.  The law was updated in 2016 to ban commercial surrogacy after Cambodia became a popular destination for foreigners seeking women to give birth to their children.  Developing countries have been popular for surrogacy because costs …

washington — The Federal Aviation Administration approved a license Saturday for the launch of SpaceX’s Starship 5 on Sunday after earlier saying it did not expect to make a decision until late November. Reuters first reported this week the faster than expected timetable after the FAA in September had suggested a much longer review.  SpaceX is targeting Sunday for the launch and said a 30-minute launch window opens at 7 a.m. CT (1200 GMT)  The FAA said Saturday that SpaceX had “met all safety, environmental and other licensing requirements for the suborbital test flight” for the fifth test of the Starship and has also approved the Starship 6 mission profile.  The Starship spacecraft and Super Heavy rocket are fully reusable systems designed to carry crew and cargo to Earth orbit, the Moon and beyond.  The fifth test flight of the Starship/Super Heavy from Boca Chica, Texas, includes a return to the …

YAOUNDE, CAMEROON — Humanitarian groups in Cameroon are visiting homes and villages in remote areas this week to mark Breast Cancer Awareness Month, advising women to go to hospitals for free screening and treatment. About 60% of the more than 7,000 women diagnosed with breast cancer in Cameroon this year have died because they were late in getting to hospitals, officials say. Breast cancer deaths are highly unreported because families abandon women to die at home. Thirty-year-old history student Emilie Nadege Atangana told a group of women and girls at the University of Yaounde 1 campus how she was psychologically and emotionally traumatized after receiving a diagnosis of breast cancer in 2020. Most of her relatives, friends and fellow students said she would not live long and abandoned her, she said. Atangana said she found hope when medical staff members of the Yaounde Gynaecology, Obstetrics and Pediatrics Hospital told her that …

chicago — With a neon-green net in hand, Annette Prince briskly walks a downtown Chicago plaza at dawn, looking left and right as she goes. It’s not long before she spots a tiny yellow bird sitting on the concrete. It doesn’t fly away, and she quickly nets the bird, gently places it inside a paper bag and labels the bag with the date, time and place. “This is a Nashville warbler,” said Prince, director of the Chicago Bird Collision Monitors, noting that the bird must have flown into a glass window pane of an adjacent building. “He must only weigh about two pennies. He’s squinting his eyes because his head hurts.” For rescue groups like the Chicago Bird Collision Monitors, this scene plays out hundreds of times each spring and fall after migrating birds fly into homes, small buildings and sometimes Chicago’s skyscrapers and other hulking buildings. A stark sign of …

The power of simple prayer to heal illness is not clear, according to scientists, and is difficult to study. Whatever your faith, when you’re sick, you should seek treatment from a doctor. But in Nigeria, some people choose spiritual healers and miracle cures over orthodox medicine and hospitals. That creates some dangerous situations. Timothy Obiezu reports from Abuja. …

NEW YORK — Prepare to spot a rare, bright comet. The space rock is slinging toward Earth from the outer reaches of the solar system and will make its closest pass Saturday. It should be visible through the end of October, clear skies permitting. Comet Tsuchinshan-Atlas should be bright enough to see with the naked eye, but binoculars and telescopes will give a better view. “It’ll be this fuzzy circle with a long tail stretching away from it,” said Sally Brummel, planetarium manager at the Bell Museum in Minnesota. What is a comet? Comets are frozen leftovers from the solar system’s formation billions of years ago. They heat up as they swing toward the sun, releasing their characteristic streaming tails. In 2023, a green comet that last visited Earth 50,000 years ago zoomed by the planet again. Other notable flybys included Neowise in 2020, and Hale-Bopp and Hyakutake in the mid …
