When a woman has a mammogram, the most important finding is whether there's any sign of breast cancer. The second most important finding is whether her breasts are dense. Since early September, a new U.S. rule requires mammography centers to inform women about their breast density — information that isn't entirely new for some women because many states already had similar requirements. Here's what to know about why breast density is important. Are dense breasts bad? No, dense breasts are not bad. In fact, they're quite normal. About 40% of women ages 40 and older have dense breasts. Women of all sizes can have dense breasts. It has nothing to do with breast firmness. And it only matters in the world of breast cancer screening, said Dr. Ethan Cohen of…

WINDHOEK, NAMIBIA — Namibians who are part of the LGBTQ+ community often find it difficult to get decent health care and many report discriminatory practices within the health care system. For example, when 20-year-old Immanuel Uirab sought contraception at a health facility, the nurse on duty would not assist him. “I don’t know if it’s the shorts I was wearing or you can generally just tell by looking at me that I am gay,” he said, “but then this particular nurse ... came out and she was, like, ‘No, we don’t offer contraceptives for people who practice sodomy. We can’t do that for you. ... You can go buy them if you want to use them in your private space, but we ... won’t give them to you because our government…

washington — The Orionids — one of two annual meteor showers from Halley's comet — peak early Monday. A bright waning moon may make them difficult to spot. The Orionid meteor shower can be unpredictable. It shines like a fireworks display in some years but is fairly slow in other years. This highly variable shower may result in anywhere from 20 to 60 visible meteors per hour under ideal viewing conditions, said NASA's Bill Cooke. This year's peak activity happens on a night when a waning moon is 83% full. The shower lasts through November 22. Here's what to know about the Orionids and other meteor showers. What is a meteor shower? Multiple meteor showers occur annually and don't require special equipment to see them. Most meteor showers originate from the…

Scientists say beef production takes a heavy toll on the environment. Cattle produce methane, a powerful planet-warming gas, and forests get cut down for pastures. But one farm in northern Colombia hopes to show ranching can have a lighter footprint on the planet. Austin Landis travelled to Montería in northern Colombia for a closer look at what could be a revolution in sustainable cattle ranching. ...

The U.S. Supreme Court declined on Wednesday to put on hold a new federal rule targeting carbon pollution from coal- and gas-fired power plants at the request of numerous states and industry groups in another major challenge to President Joe Biden's efforts to combat climate change. The justices denied emergency requests by West Virginia, Indiana and 25 other states — most of them Republican led — as well as power companies and industry associations, to halt the Environmental Protection Agency rule while litigation continues in a lower court. The regulation, aimed at cutting greenhouse gas emissions that drive climate change, took effect July 8. The rule would require existing coal and new natural gas-fired plants eventually to reduce emissions including by capturing and storing carbon dioxide. The EPA's new rule,…

A nationwide recall of meat and poultry products potentially contaminated with listeria has expanded to nearly 15.4 million kilograms (12 million pounds) and now includes ready-to-eat meals sent to U.S. schools, restaurants and major retailers, federal officials said. The updated recall includes prepared salads, burritos and other foods sold at stores including Costco, Trader Joe's, Target, Walmart and Kroger. The meat used in those products was processed at a Durant, Oklahoma, manufacturing plant operated by BrucePac. The Woodburn, Oregon-based company sells precooked meat and poultry to industrial, foodservice and retail companies across the country. Routine testing found potentially dangerous listeria bacteria in samples of BrucePac chicken, officials with the U.S. Agriculture Department said. No illnesses have been confirmed in connection with the recall, USDA officials said. The U.S. Centers for…

Since the U.S. Supreme Court sent the issue of abortion back to the states in 2022, Democrats have mobilized to protect abortion rights while Republicans have worked to restrict the procedure on religious and moral grounds. The issue is motivating voters to go to the polls this election year. VOA Congressional Correspondent Katherine Gypson has more from Nevada. Videographer: Mary Cieslak ...

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…

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…

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…

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…

PHOENIX — On just one sweltering day during the hottest June on record in Phoenix, a 38-year-old man collapsed under a freeway bridge and a 41-year-old woman was found slumped outside a business. Both had used methamphetamine before dying from an increasingly dangerous mix of soaring temperatures and stimulants. Meth is showing up more often as a factor in the deaths of people who died from heat-related causes in the U.S., according to an Associated Press analysis of data from the U.S. Centers for Disease Control and Prevention. Death certificates show about one in five heat-related deaths in recent years involved methamphetamine. In Arizona, Texas, Nevada and California, officials found the drug in nearly a third of heat deaths in 2023. Meth is more common in heat-related deaths than the deadly…

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…

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…

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.…

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…

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…

UNITED NATIONS — More than 370 million girls and women alive today, or one in every eight worldwide, experienced rape or sexual assault before the age of 18, the United Nations children's agency said Wednesday. The number rises to 650 million, or one in five, when taking into account "non-contact" forms of sexual violence, such as online or verbal abuse, UNICEF reported, in what it called the first global survey of the problem. The report said that while girls and women were worst affected, 240 million to 310 million boys and men, or around 1 in 11, have experienced rape or sexual assault during childhood. "The scale of this human rights violation is overwhelming, and it's been hard to fully grasp because of stigma, challenges in measurement, and limited investment in…

STOCKHOLM — Scientists David Baker, Demis Hassabis and John Jumper won the 2024 Nobel Prize in Chemistry, the award-giving body said on Wednesday, for their work on the structure of proteins. The prize, widely regarded as among the most prestigious in the scientific world, is awarded by the Royal Swedish Academy of Sciences and is worth $1.1 million. "One of the discoveries being recognized this year concerns the construction of spectacular proteins. The other is about fulfilling a 50-year-old dream: predicting protein structures from their amino acid sequences," the academy said in a statement. Half the prize was awarded to Baker "for computational protein design" while the other half was shared by Hassabis and Jumper "for protein structure prediction," the academy said. The third award to be handed out every year,…

Abuja, Nigeria — Cholera is surging in Nigeria, health officials said this week, with the number of cases and deaths increasing by more than 200% this year. The Nigerian Center for Disease Control said in this week's epidemiological report that the country has recorded nearly 11,000 cases of cholera this year — a 220% increase compared with the same point in 2023. The report said fatalities over the same periods have increased from 106 to 359 — a rise of 239%. The state of Lagos accounted for 43% of the nation's cases, while Kano, Katsina, Jigawa and Borno also recorded significant numbers. Last month, the worst flooding in 30 years ravaged conflict-ridden Borno state, worsening an already dire humanitarian situation there. Hundreds of thousands of people were displaced and moved to…

new york — Humanity is hitting the upper limit of life expectancy, according to a new study. Advances in medical technology and genetic research — not to mention larger numbers of people making it to age 100 — are not translating into marked jumps in lifespan overall, according to researchers who found shrinking longevity increases in countries with the longest-living populations. "We have to recognize there's a limit" and perhaps reassess assumptions about when people should retire and how much money they'll need to live out their lives, said S. Jay Olshansky, a University of Illinois-Chicago researcher who was lead author of the study published Monday by the journal Nature Aging. Mark Hayward, a University of Texas researcher not involved in the study, called it "a valuable addition to the mortality…
