Marvel's 'Ironheart': Release Date and How to Watch
When Black Panther: Wakanda Forever came out in fall 2022, the Ryan Coogler-directed film introduced Dominique Thorne as Riri Williams, a teenage MIT student whose brilliance created a vibranium detector. Now, the character is debuting in her own streaming TV show: Ironheart. Pulled from Marvel's comic books, the young inventor possesses genius-level intelligence and found Tony Stark an inspiration. Riri's gift for robotics led her to make an armored suit that's been compared to Iron Man's, and they both were driven to serve mankind. The show sees her return to Chicago after the events of Wakanda Forever (where she helped battle Namor alongside Shuri), and viewers will see her tech take on magic when The Hood (played by Anthony Ramos) arrives on the scene in the upcoming new series. In addition to Thorne and Ramos, the cast also features Lyric Ross, Alden Ehrenreich, Anji White, Regan Aliyah, and Manny Montana. Coogler and Kevin Feige are among the series' executive producers. Get the details below on when to watch all six episodes of Ironheart.

Evidence is building that people were in the Americas 23,000 years ago
When you buy through links on our articles, Future and its syndication partners may earn a commission. The age of "rarely preserved" ancient human footprints dotting the landscape at White Sands National Park in New Mexico has been hotly debated for years. Now, a new study has found that these footprints really are around 23,000 years old — but the date isn't accepted by everyone. If the 23,000-year-old age is accurate, it would mean that humans were in North America around the peak of the Last Glacial Maximum, the coldest part of the last ice age — far earlier than archaeologists had previously thought. In the new study, the researchers radiocarbon-dated organic sediment in core samples from the site, which provided dates for the footprints as well as for the entire paleolake and river system that once existed there. The analysis was done in labs unaffiliated with earlier studies. "Our data supports the original data" that dated the site to 23,000 years ago, study first author Vance Holliday, a professor emeritus of anthropology and geosciences at the University of Arizona, told Live Science. "Plus, we now have an idea of what the landscape was like when people were out there." The saga of dating the roughly 60 footprints goes back to 2021, when a study reported the discovery of the footprints and dated them to between 21,000 and 23,000 years old. However, a 2022 rebuttal took issue with using the seeds of ditch grass (Ruppia cirrhosa), a water plant, for radiocarbon dating. Water plants get their carbon from underwater, which can be much older than carbon from the atmosphere. This can skew the levels of carbon 14, a radioactive version of the atom, in the samples, making the plants appear older than they really are. So, in 2023, researchers redated the site with optically stimulated luminescence (OSL) dating, which revealed when quartz or feldspar grains in the tracks were last exposed to sunlight, and radiocarbon dating of ancient conifer pollen from the footprint layer — which proved to be another way to use carbon 14 without relying on water plants. Related: The 1st Americans were not who we thought they were Again, the scientists found that the footprints were 21,000 to 23,000 years old. While some scientists called the results "very convincing," others, including those who wrote the 2022 rebuttal, were still wary of the results, saying the samples weren't taken from the right layer. Now, the new study offers more evidence that the footprints date to the Last Glacial Maximum, when the area was a vast wetland inhabited by ice age animals. The footprints likely came from hunter-gatherers who arrived in the Americas after traveling along the Bering Land Bridge, which connected Siberia and Alaska when sea levels were lower, research suggests. For decades, researchers thought the earliest Americans were the Clovis, who lived in North America around 13,000 years ago. But the footprint discovery and others are slowly revealing that Indigenous people reached the Americas much earlier than thought. Holliday has been working at White Sands since 2012, and some of his data was used in the original 2021 study, making him a co-author, he noted. This time, Holliday and his colleagues radiocarbon-dated mud cores from the site. They found that the trackways date to between 20,700 and 22,400 years ago, which closely matches the original dates. When added together, there are now a total of 55 radiocarbon-dated samples of mud, seeds and pollen from the footprint layer that support the 21,000- to 23,000-year-old dates, Holliday said. Ancient human footprints are "so rarely preserved," he said. And now, scientists have "dates on three different materials that all coincide" on a time for these tracks. "You get to the point where it's really hard to explain all this away," he said in a statement. "As I say in the paper, it would be serendipity in the extreme to have all these dates giving you a consistent picture that's in error." However, more work is needed to securely date the footprints at White Sands, said Michael Waters, director of the Center for the Study of the First Americans at Texas A&M University, who was not involved with the study. "Even with these new data, I remain concerned about the radiocarbon ages generated to date the footprints at White Sands," Waters told Live Science in an email. He reiterated the known Ruppia issue, saying the radiocarbon dates "are likely too old" because the plant got its carbon from the water. In fact, the same underwater carbon issues could have also affected the sediments dated in the new study, he said. "The new ages on bulk organic sediments presented in this paper are interesting, but it is unclear about the origin of the carbon being dated," Waters said.

Furthermore, Holliday and his colleagues acknowledge that their study doesn't address another hot-button issue: Where are the artifacts or settlements from these ice age people at White Sands? That question remains to be answered, Holliday said. But it's unlikely that hunter-gatherers would have left behind valuable items in the short time it took them to trek around the wetland. "These people live by their artifacts, and they were far away from where they can get replacement material," Holliday said in the statement. "They're not just randomly dropping artifacts. It's not logical to me that you're going to see a debris field."

Parents, You're Focusing on the Wrong Part of Your Kid's Screen Use
When it comes to monitoring kids and technology, parents are all doing the best we can. Especially in the summertime when rules fly out the window. However, a new study found that parents may actually be worried about the wrong thing when it comes to kids and screens. A study published June 18 in JAMA, a journal of the American Medical Association, found that the amount of time kids spent on social media, mobile phones, and video games wasn't linked to more internalized symptoms of mental health issues like anxiety and depression. Surprisingly, it also wasn't associated with externalized symptoms of mental health problems like rule breaking, aggression, suicidal behaviors, or suicidal ideation. This sounds good right? The problem is, researchers found that screen addiction was linked to both internal and external symptoms of mental health problems. More from SheKnows PopSockets Partnered With This Celeb-Loved Jewelry Brand to Drop Beach-Chic Limited-Edition Accessories There is a difference; a subtle distinction with big consequences. Yunyu Xiao, lead study author and an assistant professor in the department of population health sciences and department of psychiatry at Weill Cornell Medical College in New York, explained addiction as 'excessive use' that interferes with home responsibilities, schoolwork or other activities, per CNN. 'They find a craving for it and cannot stop using it,' he explained. The study found one in two of the young people in the study were on a 'high trajectory of addictive use' for mobile phones, while over 40 percent were on the same path for video games. For the kids with high or increasing use of social media and mobile phones, they were two to three times more likely to engage in suicidal behavior and suicidal ideations than kids on the lower trajectory. These kids also had increased risk of symptoms of mental health problems, with a high use of video games associated with a greater risk of symptoms of mental health problems, suicidal behaviors, and suicidal ideation. It's absolutely heartbreaking! And teens know they need help. In Feb. 2025, SheKnows spoke with teens in New York City about their phone use, and the results were concerning. One 16-year-old named Annabella told us that she spends 12 hours on her phone. 'My friends are on it [their phones], I feel like I couldn't get off it or certain apps, I don't know — I'm just, like, addicted,' Annabella admitted. The Anxious Generation author Jonathan Haidt recommends not giving your child a phone until high school, not allowing social media until 16, and encouraging real-world independence and risk-taking in kids. Ariana Hoet, Ph.D., executive clinical director of children's mental health organization On Our Sleeves, previously told SheKnows that she recommends designated screen-free times every day: during dinner, for example, and powering phones down a couple of hours before bedtime. You should also talk about screens as a family. 'You can talk about what social media platforms you're going to use. Who do you follow? What do you post? And then most importantly, when are the screen-free times? What are other activities you're doing? Who do you go to if you're worried about something?' Dr. Hoet told us. 'You also need to establish the consequences: what happens if these rules are broken?' Dr. Becky Kennedy, psychologist, author, and mom of three previously told SheKnows that screen time isn't inherently bad for kids. It all depends on what the screen time is being used for and if your kids have a healthy balance. She suggests parents define screen time boundaries in advance, encourage kids to learn on their screen before playing, and anticipate the meltdowns around screen time by setting firm boundaries about when to put it up at the end of the day. 'To me, if you're a parent who's just struggling with screen time with your kid, you're probably doing it right. It's a tool we need to use,' she told us. 'It's something I don't think parents need to feel guilty about. It's just something parents need to have a level of mindfulness about relative to making sure we're setting up our home today for success — but that we're also setting up our kids for success long-term.' Look out for these signs that your child might be addicted to cell phones or video games, per the Mayo Clinic: Intense urges for screen time or video games that block out other thoughts. Cutting back on social or recreational activities because of preference for screen time or video games. Feeling irritable, anxiety, or anger when forced to stop playing, even for brief periods of time. Lying to others about the extent of their use. Needing more screen time over time to get the same level of enjoyment. Neglecting their appearance, including lack of interest in grooming or clothing.
