Doctored images have been around for decades. The term "Photoshopped" is part of everyday language. But in recent years, it has seemingly been replaced by a new word: deepfake. It's almost everywhere online, but you likely won't find it in your dictionary at home. What exactly is a deepfake, and how does the technology work? RELATED STORY | Scripps News Reports: Sex, Lies, and Deepfakes A deepfake is an image or video that has been generated by artificial intelligence to look real. Most deepfakes use a type of AI called a "diffusion model." In a nutshell, a diffusion model creates content by stripping away noise. "With diffusion models, they found a very clever way of taking an image and then constructing that procedure to go from here to there," said Lucas Hansen said. He and Siddharth Hiregowdara are cofounders of CivAI, a nonprofit educating the public on the potential — and dangers — of AI. How diffusion models work It can get complicated, so imagine the AI – or diffusion model – as a detective trying to catch a suspect. Like a detective, it relies on its experience and training. It recalls a previous case -– a sneaky cat on the run. Every day it added more and more disguises. On Monday, no disguise. Tuesday, it put on a little wig. Wednesday, it added some jewelry. By Sunday, it's unrecognizable and wearing a cheeseburger mask. The detective learned these changes can tell you what it wore and on what day. AI diffusion models do something similar with noise, learning what something looks like at each step. "The job of the diffusion model is to remove noise," Hiregowdara said. "You would give the model this picture, and then it will give you a slightly de-noised version of this picture." RELATED STORY | Scripps News got deepfaked to see how AI could impact elections When it's time to solve the case and generate a suspect, we give it a clue: the prompts we give when we create an AI-generated image. "We have been given the hint that this is supposed to look like a cat. So what catlike things can we see in here? Okay, we see this curve, maybe that's an ear," Hiregowdara said. The "detective" works backward, recalling its training. It sees a noisy image. Thanks to the clue, it is looking for a suspect — a cat. It subtracts disguises (noise) until it finds the new suspect. Case closed. Now imagine the "detective" living and solving crimes for years and years. It learns and studies everything — landscapes, objects, animals, people, anything at all. So when it needs to generate a suspect or an image, it remembers its training and creates an image. Deepfakes and faceswaps Many deepfake images and videos employ some type of face swapping technology. You've probably experienced this kind of technology already — faceswapping filters like on Snapchat, Instagram or Tiktok use technology similar to diffusion models, recognizing faces and replacing things in real time. "It will find the face in the image and then cut that out kind of, then take the face and convert it to its internal representation," Hansen said. The results are refined then repeated frame by frame. The future and becoming our own detectives As deepfakes become more and more realistic and tougher to detect, understanding how the technology works at a basic level can help us prepare for any dangers or misuse. Deepfakes have already been used to spread election disinformation, create fake explicit images of a teenager, even frame a principal with AI-created racist audio. "All the netizens on social media also have a role to play," Siwei Lyu said. Lyu is a SUNY Empire Innovation Professor at the University of Buffalo's Department of Computer Science and Engineering, and the director of the Media Forensics Lab. His team has created a tool to help spot deepfakes called "DeepFake-o-meter." "We do not know how to handle, how to deal, with these kinds of problems. It's very new. And also requires technical knowledge to understand some of the subtleties there," Lyu said. "The media, the government, can play a very active role to improve user awareness and education. Especially for vulnerable groups like seniors, the kids, who will start to understand the social media world and start to become exposed to AI technologies. They can easily fall for AI magic or start using AI without knowing the limits." RELATED STORY | AI voice cloning: How programs are learning to pick up on pitch and tone Both Lyu and CivAI believe in exposure and education to help combat any potential misuse of deepfake technology. "Our overall goal is that we think AI is going t impact pretty much everyone in a lot of different ways," Hansen said. "And we think that everyone should be aware of the ways that it's going to change them because it's going to impact everyone." "More than just general education — just knowing the facts and having heard what's going to happen," he added. "We want to give people a really intuitive experience of what's going on." Hansen goes on to explain CivAI's role in educating the public. "We try and make all of our demonstrations personalized as much as possible. What we're working on is making it so people can see it themselves. So they know it's real, and they feel that it's real," Hansen said. "And they can have a deep gut level feel for tthe impact that it's going to have." "A big part of the solution is essentially just going to be education and sort of cultural changes," he added. "A lot of this synthetic content is sort of like a new virus that is attacking society right now, and people need to become immune to it in some ways. They need to be more suspicious about what's real and what's not, and I think that will help a lot as well."
Celsius Holdings, Inc. Shareholder Notice: Robbins LLP Reminds Investors of the CELH Class ...NoneJimmy Carter, the 39th US president, has died at 100 ATLANTA (AP) — Former U.S. President Jimmy Carter has died. He was 100 years old and had spent roughly 22 months in hospice care. The Georgia peanut farmer served one turbulent term in the White House before building a reputation as a global humanitarian and champion of democracy. He defeated President Gerald Ford in 1976 promising to restore trust in government but lost to Ronald Reagan four years later amid soaring inflation, gas station lines and the Iran hostage crisis. He and his wife Rosalynn then formed The Carter Center, and he earned a Nobel Peace Prize while making himself the most internationally engaged of former presidents. The Carter Center said he died peacefully Sunday afternoon in Plains, Georgia, surrounded by his family. Jimmy Carter: Many evolutions for a centenarian ‘citizen of the world’ PLAINS, Ga. (AP) — The 39th and longest-lived U.S. president, James Earl Carter Jr., died Sunday at the age of 100. His life ended where it began, in Plains, Georgia. He left and returned to the tiny town many times as he climbed to the nation’s highest office and lost it after four tumultuous years. Carter spent the next 40 years setting new standards for what a former president can do. Carter wrote nearly a decade ago that he found all the phases of his life challenging but also successful and enjoyable. The Democrat's principled but pragmatic approach defied American political labels, especially the idea that one-term presidents are failures. The Latest: Former President Jimmy Carter is dead at age 100 Former President Jimmy Carter has died at the age of 100. The 39th president of the United States was a Georgia peanut farmer who sought to restore trust in government when he assumed the presidency in 1977 and then built a reputation for tireless work as a humanitarian. He earned a Nobel Peace Prize in 2002. He died Sunday, more than a year after entering hospice care, at his home in Plains, Georgia. Carter was sworn in as president on Jan. 20, 1977, after defeating President Gerald R. Ford in the 1976 general election. He left office on Jan. 20, 1981, following his 1980 general election loss to Ronald Reagan. Jet crash disaster in South Korea marks another setback for Boeing WASHINGTON (AP) — A machinists strike. Another safety problem involving its troubled top-selling airliner. A plunging stock price. 2024 was already a dispiriting year for Boeing, the American aviation giant. But when one of the company’s jets crash-landed in South Korea on Sunday, killing all but two of the 181 people on board, it brought to a close an especially unfortunate year for Boeing. The cause of the crash remains under investigation, and aviation experts were quick to distinguish Sunday’s incident from the company’s earlier safety problems. Alan Price, an airline consultant, said it would be inappropriate to link the incident Sunday to two fatal crashes involving Boeing’s troubled 737 Max jetliner in 2018 and 2019. South Korean authorities seek warrant to detain impeached President Yoon in martial law probe SEOUL, South Korea (AP) — South Korean law enforcement officials have requested a court warrant to detain impeached President Yoon Suk Yeol as they investigate whether his short-lived martial law decree this month amounted to rebellion. The Corruption Investigation Office for High-Ranking Officials, which is leading a joint investigation with police and military authorities into the power grab that lasted only a few hours, confirmed it requested the warrant on Monday. Investigators plan to question Yoon on charges of abuse of authority and orchestrating a rebellion. Tornadoes in Texas and Mississippi kill 2 and injure 6 as severe weather system moves east HOUSTON (AP) — A strong storm system is threatening to whip up tornadoes in parts of the U.S. Southeast, a day after severe weather claimed at least two lives as twisters touched down in Texas and Mississippi. Strong storms moving eastward Sunday are expected to continue producing gusty, damaging winds, hail and tornadoes through Sunday. That is according to National Weather Service meteorologist Frank Pereira. So far, the line of severe weather has led to about 40 tornado reports from southeastern Texas to Alabama, Pereira said, but those reports remain unconfirmed until surveys of damage are completed. Israeli hospital says Netanyahu has undergone successful prostate surgery TEL AVIV, Israel (AP) — An Israeli hospital says Prime Minister Benjamin Netanyahu has undergone successful prostate surgery. Jerusalem’s Hadassah Medical Center said his prostate was removed late Sunday and that he was recovering. Netanyahu’s office had said Justice Minister Yariv Levin, a close ally, would serve as acting prime minister during the procedure. Doctors ordered the operation after detecting an infection last week. Netanyahu is expected to remain hospitalized for several days. With so much at stake, Netanyahu’s health in wartime is a concern for both Israelis and the wider world. Syria's de facto leader says it could take up to 4 years to hold elections BEIRUT (AP) — Syria’s de facto leader has said it could take up to four years to hold elections in Syria, and that he plans on dissolving his Islamist group that led the country’s insurgency at an anticipated national dialogue summit for the country. Ahmad al-Sharaa, who leads Hayat Tahrir al-Sham, the group leading the new authority in Syria, made the remarks in an interview Sunday. That's according to the Saudi television network Al-Arabiyya. It comes almost a month after a lightning insurgency led by HTS overthrew President Bashar Assad’s decades-long rule, ending the country’s uprising-turned civil war that started back in 2011. A fourth infant dies of the winter cold in Gaza as families share blankets in seaside tents DEIR AL-BALAH, Gaza Strip (AP) — A fourth infant has died of hypothermia in Gaza, where hundreds of thousands of Palestinians displaced by nearly 15 months of war are huddled in tents along the rainy, windswept coast as winter arrives. The baby's father says the 20-day-old child was found with his head as “cold as ice” Sunday morning in their tent. The baby’s twin brother was moved to the intensive care unit of Al-Aqsa Martyrs Hospital. Their father says the twins were born one month premature and spent just a day in hospital, which like other Gaza health centers has been overwhelmed and only partially functions. Musk causes uproar for backing Germany's far-right party ahead of key elections BERLIN (AP) — Tech entrepreneur Elon Musk has caused uproar after backing Germany’s far-right party in a major newspaper ahead of key parliamentary elections in the Western European country, leading to the resignation of the paper’s opinion editor in protest. Germany is to vote in an early election on Feb. 23 after Chancellor Olaf Scholz’s three-party governing coalition collapsed last month in a dispute over how to revitalize the country’s stagnant economy. Musk’s guest opinion piece for Welt am Sonntag, published in German over the weekend, was the second time this month he supported the Alternative for Germany, or AfD.

Social media firms raise 'serious concerns' over Australian U-16 banAustralia's proposal to ban under-16s from social media platforms is "rushed", social media companies claimed Tuesday, expressing "serious concerns" about potential unintended consequences. The landmark legislation would force social media firms to prevent young teens from accessing their platforms or face fines of up to Aus$50 million (US$32.5 million). Platforms such as X, Snapchat, TikTok, and Meta have criticised the 24-hour time frame given for stakeholder comments, claiming a lack of consultation and inadequate details about how the legislation would work. X said in its submission that it had "serious concerns" the ban would have "a negative impact" on children, adding it breached their "rights to freedom of expression and access to information". The company added that the proposed law was "vague" and "highly problematic" and that there was "no evidence" that it would work. Australia is among the vanguard of nations trying to clean up social media, and the proposed age limit would be among the world's strictest measures aimed at children. The proposed laws, which were presented to parliament last week, would also include robust privacy provisions that require tech platforms to delete any age-verification information collected. The government is trying to approve the law this week, before parliament breaks for the rest of the year. Meta, which owns Facebook and Instagram, said in its submission the ban would "fail" in its current form because there was not enough consultation with stakeholders. "More time should be taken to get this bill right," it said. TikTok raised concerns over the privacy provisions -- including that they overlapped and contradicted other legislation -- and the limited time to consult stakeholders. Sign up to get our free daily email of the biggest stories! "Its rushed passage poses a serious risk of further unintended consequences," the company's submission said. Key details about how social media companies are expected to enforce the ban remain unclear. Some companies will be granted exemptions from the ban, such as YouTube, which teenagers may need to use for school work or other reasons. Once celebrated as a means of staying connected and informed, social media platforms have been tarnished by cyberbullying, the spread of illegal content, and election-meddling claims. Australian Prime Minister Anthony Albanese insisted Tuesday that "social media is causing social harm". "It can be a weapon for bullies, a platform for peer pressure, a driver of anxiety, a vehicle for scammers and, worst of all, a tool for online predators," he wrote in an opinion piece. "And because it is young Australians who are most engaged with this technology -- it is young Australians who are most at risk." The laws would give families "peace of mind" that their children's well-being and mental health were being prioritised, he said. If the proposed law passes, tech platforms would be given a one-year grace period to figure out how to implement and enforce the ban. The proposal comes just months before Australians go to the polls in a general election that must be held in the first half of 2025. lec/arb/fox

More or less: Erratic nature of UK’s electric vehicle charging networkGlobal stock markets mostly retreated Tuesday as traders eyed looming US inflation data and a key European interest rate call amid global political upheaval. After winning numerous records in the weeks since the November 5 US presidential election, US stocks fell for the second straight day as analysts pointed to profit-taking. But Alphabet jumped more than five percent after Google showed off a new quantum computing chip that it described as a significant breakthrough in the field, arguing it could lead to advances in drug discovery, fusion energy and other areas. The Paris stock market retreated as French party leaders gathered at President Emmanuel Macron's Elysee Palace office to chart a route towards a new government. The euro also fell ahead of the European Central Bank's monetary policy meeting on Thursday. The ECB is expected to lower interest rates by 25 basis points amid weak eurozone growth. Independent analyst Andreas Lipkow said traders were taking a cautious approach ahead of the ECB meeting. The main US indexes struggled as traders eyed US consumer price inflation (CPI) data due Wednesday, which could play a role in whether the US Federal Reserve decides to cut interest rates next week. On Wall Street, "tomorrow's CPI report is in full focus with a looming rate-decision from the Fed coming," analyst Bret Kenwell of trading platform eToro said in a note. Following recent spending and jobs data "traders have felt even more emboldened to bet on a December rate cut, while the Fed has done little... to quiet that expectation," he added. Earlier, stock markets weighed "concerns that China's economic stimulus measures might not have a long-lasting effect", noted Dan Coatsworth, investment analyst at AJ Bell. The growth plan comes as Beijing contemplates Donald Trump's second term in the White House. The US president-elect has indicated he will reignite his hardball trade policies, fueling fears of another standoff between the economic superpowers.
