The expanded Big Ten is poised to be a major player in this season's College Football Playoff. The 18-team conference had three of the top-four teams in the AP poll this week — No. 1 Oregon, No. 2 Ohio State and No. 4 Penn State. A one-loss Indiana team is ranked 10th but is still very much a contender to make the playoff, given how many Southeastern Conference teams have three defeats or more. Indiana's rise has been perhaps the Big Ten's biggest story this season. Much of the spotlight was on newcomers Oregon, Southern California, UCLA and Washington, but aside from the top-ranked Ducks, that foursome has struggled to impress. Meanwhile, the Hoosiers won their first 10 games under new coach Curt Cignetti before losing at Ohio State last weekend. Oregon beat Ohio State 32-31 back in October, and if the Buckeyes beat rival Michigan this weekend, they'll earn a rematch with the Ducks for the Big Ten title. And it's entirely possible another matchup between those two teams awaits in the CFP. Dillon Gabriel has quarterbacked Oregon to an unbeaten record, throwing for 3,066 yards and 22 touchdowns in 11 games. But don't overlook Iowa's Kaleb Johnson and his 21 rushing TDs, and quarterback Kurtis Rourke has been a big part of Indiana's improvement. Penn State's Abdul Carter has eight sacks and two forced fumbles and could be one of the top edge rushers drafted this year. Oregon (11-0, 8-0), Ohio State (10-1, 7-1), Penn State (10-1, 7-1), Indiana (10-1, 7-1), Illinois (8-3, 5-3), Iowa (7-4, 5-3), Michigan (6-5, 4-4), Minnesota (6-5, 4-4), Washington (6-5, 4-4), Southern California (6-5, 4-5), Nebraska (6-5, 3-5) and Rutgers (6-5, 3-5) have already reached the six-win mark for bowl eligibility. Michigan State (5-6, 3-5) and Wisconsin (5-6, 3-5) can join them. There may not be many firings in general at the top level of college football. The prospect of sharing revenue with athletes in the future might lead schools to be more judicious about shedding one coach and hiring a new one. Who should be most worried in the Big Ten? Well, Lincoln Riley is struggling to stay above .500 in his third season at USC. Purdue is 1-10, but coach Ryan Walters is only in his second season. Maryland's Mike Locksley has been there six years and his Terrapins are 4-7, but this was his first real step backward after guiding the team to three straight bowl wins. Cignetti has shown it is possible for a coaching change to push a previously moribund program to some impressive heights in a short amount of time — but the improvement has been more incremental at Michigan State following Jonathan Smith's arrival. Sherrone Moore wasn't a completely unknown commodity at Michigan after he won some massive games in place of a suspended Jim Harbaugh last year. But in his first season completely at the helm, the Wolverines have declined significantly following their national title a season ago. The Big Ten is home to one of the most dynamic freshmen in the country in Ohio State receiver Jeremiah Smith. He has 52 catches for 899 yards and nine touchdowns. Highly touted quarterback Dylan Raiola has teamed up with fellow freshman Jacory Barney (49 catches) to lead Nebraska to bowl eligibility. Ohio State is on track to land the Big Ten's top class, according to 247 Sports, but the big news recently was quarterback Bryce Underwood flipping from LSU to Michigan. If the Wolverines do in fact keep Underwood in his home state, that would be a big development for Moore.Cardin visits Western Maryland for farewell tour

Millions of people now have access to artificial intelligence like ChatGPT. After Apple Intelligence integrated ChatGPT into its platform, anyone with an iPhone, iPad or Mac can now ask complex questions without going to a separate app or website. This long-awaited integration may spark questions like, how does ChatGPT work? What are chatbots? ChatGPT, operated by OpenAI, is an artificial intelligence chatbot like Google’s Gemini, Anthropic’s Claude, or Meta AI. These chatbots use a type of AI called a “large language model.” They understand text and generate words to sound human. “It’s almost boring now to say this,” said Daniel Dugas, an AI and robotics scientist based in Switzerland. He wrote a visualized explanation of earlier AI GPT models. “The fact that I can talk to my computer and have a semi-coherent conversation is — it’s just unbelievable,” “As an engineer, I immediately was pushed to the direction of, OK, how do we make something like intelligence?” Dugas said. While large language models may seem intelligent, they essentially just predict the next word — much like a phone’s text suggestions. But it’s far more complex. How ChatGPT works Large language models are trained on vast amounts of data, ranging from books to social media to much of the internet. An LLM maps out word relationships similar to the way the human brain does. Take the sentence, “Don’t put all your eggs in one.” Once you enter it into an LLM and hit send, a lot of things happen in repetition — in a fraction of a second. Step One: Tokenization and Encoding Imagine the process like an assembly line. The first step on the assembly line is to turn the sentence into something computers can definitely understand: numbers. RELATED STORY | How deepfake technology works The sentence, “Don’t put all your eggs in one” is broken down into what’s called “token IDs” that vary depending on the AI model. The sentence now becomes [91418, 3006, 722, 634, 27226, 306, 1001] You can test out tokenization using OpenAI’s tool . Step Two: Embedding Next, the resulting vector of numbers is expanded based on context. For example, the word “egg” has a lot of different meanings and connotations. If you had to map out the word mathematically, one way is to plot it onto a graph between “chicken” and “young.” On a two-dimensional graph, that’s simple. But “egg” has so many different meanings. “Egg” can be a part of an idiom, a breakfast ingredient, something associated with Easter, or a shape. Graphing this out would require multiple dimensions in a never-ending vector. We can’t imagine this, but a computer can compute it. With the sentence “Don’t put all your eggs in one” the word egg might be [27226]. With the sentence “I ate an egg for breakfast” the word egg might be [16102]. It all depends on context. These contextual adjustments are based on all the training and the neural network of word relationships, and the changes are embedded into the vector. Step Three: Transformer Architecture The vector moves down the assembly line into a “transformer architecture.” It is a series of layers that make even more adjustments to the vector of numbers. Based on the previous training, the AI has learned and decided what words carry more weight. For example, in the sentence “Don’t put all your eggs in one” the word “eggs” matters more than “one.” Adjustments to the vector of numbers occur repeatedly to make sure context and meaning are close to everything it was trained on. Step Four: Output Finally, the result goes in reverse on the assembly line to turn a vector of numbers back into a word: basket. "Don’t put all your eggs in one ... basket." Is this advanced word prediction? Is this intelligence? Are there limits? “You have papers saying, the model will never be able to create music or a model will never be able to answer a mathematical question,” Dugas said. “And they basically are crushed in the last five years.” As large language models continue to advance, it’s important to keep up with what they can do and to know how we can work with them, not for them. Even a basic understanding will help people utilize, navigate, and legislate a technology some might consider revolutionary.

CHICAGO (AP) — As Donald Trump’s Cabinet begins to take shape, those on both sides of the abortion debate are watching closely for clues about how his picks might affect reproductive rights policy in the president-elect’s second term . Trump’s cabinet picks offer a preview of how his administration could handle abortion after he repeatedly flip-flopped on the issue on the campaign trail. He attempted to distance himself from anti-abortion allies by deferring to states on abortion policy, even while boasting about nominating three Supreme Court justices who helped strike down the constitutional protections for abortion that had stood for half a century. In an NBC News interview that aired Sunday, Trump said he doesn't plan to restrict medication abortion but also seemed to leave the door open, saying “things change.” “Things do change, but I don't think it's going to change at all,” he said. The early lineup of his new administration , including nominations to lead health agencies, the Justice Department and event the Department of Veterans Affairs, has garnered mixed — but generally positive — reactions from anti-abortion groups. Abortion law experts said Trump's decision to include fewer candidates with deep ties to the anti-abortion movement could indicate that abortion will not be a priority for Trump's administration. “It almost seems to suggest that President Trump might be focusing his administration in other directions," said Greer Donley, an associate law professor at the University of Pittsburgh School of Law. Karen Stone, vice president of public policy at Planned Parenthood Action Fund , said while many of the nominees have “extensive records against reproductive health care,” some do not. She cautioned against making assumptions based on Trump's initial cabinet selections. Still, many abortion rights groups are wary, in part because many of the nominees hold strong anti-abortion views even if they do not have direct ties to anti-abortion activists. They're concerned that an administration filled with top-level officials who are personally opposed to abortion could take steps to restrict access to the procedure and funding. After Trump’s ambiguity about abortion during his campaign, "there’s still a lot we don’t know about what policy is going to look like," said Mary Ruth Ziegler, a law professor at the University of California, Davis School of Law. That approach may be revealed as the staffs within key departments are announced. Trump announced he would nominate anti-vaccine activist Robert F. Kennedy Jr. to lead the Health and Human Services Department, which anti-abortion forces have long targeted as central to curtailing abortion rights nationwide. Yet Kennedy shifted on the issue during his own presidential campaign. In campaign videos, Kennedy said he supports abortion access until viability , which doctors say is sometime after 21 weeks, although there is no defined timeframe. But he also said “every abortion is a tragedy” and argued for a national ban after 15 weeks of pregnancy, a stance he quickly walked back. The head of Health and Human Services oversees Title X funding for a host of family planning services and has sweeping authority over agencies that directly affect abortion access, including the Food and Drug Administration and Centers for Medicare and Medicaid Services. The role is especially vital amid legal battles over a federal law known as EMTALA, which President Joe Biden’s administration has argued requires emergency abortion access nationwide, and FDA approval of the abortion pill mifepristone. Mini Timmaraju, president of the national abortion rights organization Reproductive Freedom for All, called Kennedy an “unfit, unqualified extremist who cannot be trusted to protect the health, safety and reproductive freedom of American families.” His potential nomination also has caused waves in the anti-abortion movement. Former Vice President Mike Pence , a staunch abortion opponent, urged the Senate to reject Kennedy’s nomination. Marjorie Dannenfelser, president of the national anti-abortion group Susan B. Anthony Pro-Life America, said the group had its own concerns about Kennedy. “There’s no question that we need a pro-life HHS secretary," she said. Fox News correspondent Marty Makary is Trump’s pick to lead the FDA, which plays a critical role in access to medication abortion and contraception. Abortion rights groups have accused him of sharing misinformation about abortion on air. Russell Vought , a staunch anti-abortion conservative, has been nominated for director of the Office of Management and Budget. Vought was a key architect of Project 2025 , a right-wing blueprint for running the federal government. Among other actions to limit reproductive rights, it calls for eliminating access to medication abortion nationwide, cutting Medicaid funding for abortion and restricting access to contraceptive care, especially long-acting reversible contraceptives such as IUD’s. Despite distancing himself from the conservative manifesto on the campaign trail, Trump is stocking his administration with people who played central roles in developing Project 2025. Trump acknowledged that drafters of the report would be part of his incoming administration during the Sunday interview with NBC News, saying “Many of those things I happen to agree with.” “These cabinet appointments all confirm that Project 2025 was in fact the blueprint all along, and the alarm we saw about it was warranted,” said Amy Williams Navarro, director of government relations for Reproductive Freedom for All. Dr. Mehmet Oz , Trump’s choice to lead the Centers for Medicare and Medicaid Services, is a former television talk show host who has been accused of hawking dubious medical treatments and products. He voiced contradictory abortion views during his failed Senate run in 2022. Oz has described himself as “strongly pro-life, praised the Supreme Court decision overturning Roe v. Wade , claimed “life starts at conception” and referred to abortion as “murder.” But he also has echoed Trump’s states-rights approach, arguing the federal government should not be involved in abortion decisions. “I want women, doctors, local political leaders, letting the democracy that’s always allowed our nation to thrive to put the best ideas forward so states can decide for themselves,” he said during a Senate debate two years ago. An array of reproductive rights groups opposed his Senate run. As CMS administrator, Oz would be in a key position to determine Medicaid coverage for family planning services and investigate potential EMTALA violations. As Florida’s attorney general, Pam Bondi defended abortion restrictions, including a 24-hour waiting period. Now she’s Trump’s choice for attorney general . Her nomination is being celebrated by abortion opponents but denounced by abortion rights groups concerned she may revive the Comstock Act , an anti-vice law passed by Congress in 1873 that, among other things, bans mailing of medication or instruments used in abortion. An anti-abortion and anti-vaccine former Florida congressman, David Weldon, has been chosen to lead the Centers for Disease Control and Prevention, which collects and monitors abortion data across the country. Former Republican congressman Doug Collins is Trump’s choice to lead the Department of Veterans Affairs amid a political battle over abortion access and funding for troops and veterans. Collins voted consistently to restrict funding and access to abortion and celebrated the overturning of Roe v. Wade. “This is a team that the pro-life movement can work with," said Kristin Hawkins, president of the national anti-abortion organization Students for Life. ___ The Associated Press receives support from several private foundations to enhance its explanatory coverage of elections and democracy.
