Stock market today: Wall Street gains ground as it notches a winning week and another Dow recordCollege football recruit pulls off National Signing Day stunt before flipping to OregonDr Manmohan Singh - former Prime Minister of India, veteran Congress leader, noted economist, technocrat and the architect of India's liberalised economy that achieved high growth from a phenomenal low of the balance of payments crisis, died on Thursday night. Singh, who had been ailing for a while, breathed his last at Delhi's All-India Institute of Medical Sciences this evening. He was 92. The relationship between Sonia Gandhi, the Congress party matriarch, and former Prime Minister Manmohan Singh is a unique chapter in Indian politics. Their partnership, spanning over two decades, is marked by mutual respect, trust, and a shared vision for the party and country's progress. When Sonia Gandhi declined the Prime Ministership in 2004, she entrusted the role to Manmohan Singh, a seasoned economist and technocrat. This decision was seen as a testament to her confidence in Singh's abilities and integrity. Singh's tenure, which lasted a decade, was often viewed as a collaborative effort with Gandhi, who continued to lead the Congress party. Despite frequent criticism that Singh was a "puppet" of Gandhi, the duo maintained a professional synergy. Singh respected Gandhi's political acumen and her ability to rally the party, while Gandhi valued Singh's expertise in governance and his unassuming leadership style. Their partnership endured challenges, including economic downturns, corruption scandals, and political opposition. While Gandhi navigated the party's internal dynamics, Singh focused on policy and administration, creating a balance that allowed the UPA government to stay afloat for two consecutive terms. 'I knew Manmohan Singh would be better PM than me'- Sonia Gandhi Former Congress president Sonia Gandhi had once opened up about her decision to choose Manmohan Singh to lead the UPA I government at the Centre. Gandhi said that she chose Singh as the Prime Minister in 2004 as she was aware of her limitations. Sonia Gandhi was often asked about her decision to not tale up the prime minister's post after UPA's victory in the general elections in 2004. "I knew my limitations. I knew Manmohan Singh would be a better prime minister than me,” Sonia Gandhi had told a news channel while responding to a question on why she chose not to become the prime minister even after leading the UPA to power in 2004. Manmohan Singh has served as the prime minister of India for two consecutive terms, from 2004 to 2014. During his tenure, India witnessed significant economic progress. His leadership saw the introduction of key reforms such as the Right to Information Act and the Mahatma Gandhi National Rural Employment Guarantee Act. It also saw the landmark Indo-US Civil Nuclear Deal. His tenure was, however, marred by criticism over corruption scandals and accusations of indecisiveness in leadership. Manmohan Singh retired from the Rajya Sabha on April 3, 2024. Singh, the only Sikh prime minister of India was sworn into the Rajya Sabha in 1999. This was four months after he was appointed as the Finance Minister by PV Narasimha Rao.

But the Martian year, which is 687 Earth days, ends in a very different way in the planet’s northern hemisphere than it does in Earth’s northern hemisphere: While winter’s kicking in here, spring is starting there. That means temperatures are rising and ice is thinning, leading to frost avalanches crashing down cliffsides, carbon dioxide gas exploding from the ground, and powerful winds helping reshape the north pole. “Springtime on Earth has lots of trickling as water ice gradually melts. But on Mars, everything happens with a bang,” said Serina Diniega, who studies planetary surfaces at NASA’s Jet Propulsion Laboratory in Southern California. Mars’ wispy atmosphere doesn’t allow liquids to pool on the surface, like on Earth. Instead of melting, ice sublimates, turning directly into a gas. The sudden transition in spring means a lot of violent changes as both water ice and carbon dioxide ice — dry ice, which is much more plentiful on Mars than frozen water — weaken and break. “You get lots of cracks and explosions instead of melting,” Diniega said. “I imagine it gets really noisy.” Using the cameras and other sensors aboard NASA’s Mars Reconnaissance Orbiter (MRO), which launched in 2005, scientists study all this activity to improve their understanding of the forces shaping the dynamic Martian surface. Here’s some of what they track. In 2015, MRO’s High-Resolution Imaging Science Experiment (HiRISE) camera captured a 66-foot-wide (20-meter-wide) in freefall. Chance observations like this are reminders of just how different Mars is from Earth, Diniega said, especially in springtime, when these surface changes are most noticeable. “We’re lucky we’ve had a spacecraft like MRO observing Mars for as long as it has,” Diniega said. “Watching for almost 20 years has let us catch dramatic moments like these avalanches.” Diniega has relied on HiRISE to study another quirk of Martian springtime: gas geysers that blast out of the surface, throwing out dark fans of sand and dust. These explosive jets form due to energetic sublimation of carbon dioxide ice. As sunlight shines through the ice, its bottom layers turn to gas, building pressure until it bursts into the air, creating those dark fans of material. But to see the best examples of the newest fans, researchers will have to wait until December 2025, when spring starts in the southern hemisphere. There, the fans are bigger and more clearly defined. Another difference between ice-related action in the two hemispheres: Once all the ice around some northern geysers has sublimated in summer, what’s left behind in the dirt are scour marks that, from space, look like giant spider legs. Researchers this process in a JPL lab. For Isaac Smith of Toronto’s York University, one of the most fascinating subjects in springtime is the . Etched into the icy dome are swirling troughs, revealing traces of the red surface below. The effect is like a swirl of milk in a café latte. “These things are enormous,” Smith said, noting that some are a long as California. “You can find similar troughs in Antarctica but nothing at this scale.” Fast, warm wind has carved the spiral shapes over eons, and the troughs act as channels for springtime wind gusts that become more powerful as ice at the north pole starts to thaw. Just like the Santa Ana winds in Southern California or the Chinook winds in the Rocky Mountains, these gusts pick up speed and temperature as they ride down the troughs — what’s called an adiabatic process. IMAGE The winds that carve the north pole’s troughs also reshape , causing sand to pile up on one side while removing sand from the other side. Over time, the process causes dunes to migrate, just as it does with dunes on Earth. This past September, Smith coauthored a detailing how carbon dioxide frost settles on top of polar sand dunes during winter, freezing them in place. When the frost all thaws away in the spring, the dunes begin migrating again. Each northern spring is a little different, with variations leading to ice sublimating faster or slower, controlling the pace of all these phenomena on the surface. And these strange phenomena are just part of the seasonal changes on Mars: the southern hemisphere has its own unique activity. The University of Arizona, in Tucson, operates HiRISE, which was built by Ball Aerospace & Technologies Corp., in Boulder, Colorado. NASA’s Jet Propulsion Laboratory, a division of Caltech in Pasadena, California, manages the Mars Reconnaissance Orbiter Project for NASA’s Science Mission Directorate, Washington.

KYAN Technologies’ cancer response prediction platform shows high accuracy for leukemia in clinical study publicationFor Makenzie Gilkison, spelling is such a struggle that a word like rhinoceros might come out as “rineanswsaurs” or sarcastic as “srkastik.” The 14-year-old from suburban Indianapolis can sound out words, but her dyslexia makes the process so draining that she often struggles with comprehension. “I just assumed I was stupid,” she recalled of her early grade school years. But assistive technology powered by artificial intelligence has helped her keep up with classmates. Last year, Makenzie was named to the National Junior Honor Society. She credits a customized AI-powered chatbot, a word prediction program and other tools that can read for her. “I would have just probably given up if I didn’t have them,” she said. Artificial intelligence holds the promise of helping countless other students with a range of visual, speech, language and hearing impairments to execute tasks that come easily to others. Schools everywhere have been wrestling with how and where to incorporate AI , but many are fast-tracking applications for students with disabilities. Getting the latest technology into the hands of students with disabilities is a priority for the U.S. Education Department, which has told schools they must consider whether students need tools like text-to-speech and alternative communication devices. New rules from the Department of Justice also will require schools and other government entities to make apps and online content accessible to those with disabilities. There is concern about how to ensure students using it — including those with disabilities — are still learning. Students can use artificial intelligence to summarize jumbled thoughts into an outline, summarize complicated passages, or even translate Shakespeare into common English. And computer-generated voices that can read passages for visually impaired and dyslexic students are becoming less robotic and more natural. “I’m seeing that a lot of students are kind of exploring on their own, almost feeling like they’ve found a cheat code in a video game,” said Alexis Reid, an educational therapist in the Boston area who works with students with learning disabilities. But in her view, it is far from cheating : “We’re meeting students where they are.” Ben Snyder, a 14-year-old freshman from Larchmont, New York, who was recently diagnosed with a learning disability, has been increasingly using AI to help with homework. “Sometimes in math, my teachers will explain a problem to me, but it just makes absolutely no sense,” he said. “So if I plug that problem into AI, it’ll give me multiple different ways of explaining how to do that.” He likes a program called Question AI. Earlier in the day, he asked the program to help him write an outline for a book report — a task he completed in 15 minutes that otherwise would have taken him an hour and a half because of his struggles with writing and organization. But he does think using AI to write the whole report crosses a line. “That’s just cheating,” Ben said. Schools have been trying to balance the technology’s benefits against the risk that it will do too much. If a special education plan sets reading growth as a goal, the student needs to improve that skill. AI can’t do it for them, said Mary Lawson, general counsel at the Council of the Great City Schools. But the technology can help level the playing field for students with disabilities, said Paul Sanft, director of a Minnesota-based center where families can try out different assistive technology tools and borrow devices. “There are definitely going to be people who use some of these tools in nefarious ways. That’s always going to happen,” Sanft said. “But I don’t think that’s the biggest concern with people with disabilities, who are just trying to do something that they couldn’t do before.” Another risk is that AI will track students into less rigorous courses of study. And, because it is so good at identifying patterns , AI might be able to figure out a student has a disability. Having that disclosed by AI and not the student or their family could create ethical dilemmas, said Luis Pérez, the disability and digital inclusion lead at CAST, formerly the Center for Applied Specialized Technology. Schools are using the technology to help students who struggle academically, even if they do not qualify for special education services. In Iowa, a new law requires students deemed not proficient — about a quarter of them — to get an individualized reading plan. As part of that effort, the state’s education department spent $3 million on an AI-driven personalized tutoring program. When students struggle, a digital avatar intervenes. More AI tools are coming soon. The U.S. National Science Foundation is funding AI research and development. One firm is developing tools to help children with speech and language difficulties. Called the National AI Institute for Exceptional Education, it is headquartered at the University of Buffalo, which did pioneering work on handwriting recognition that helped the U.S. Postal Service save hundreds of millions of dollars by automating processing. “We are able to solve the postal application with very high accuracy. When it comes to children’s handwriting, we fail very badly,” said Venu Govindaraju, the director of the institute. He sees it as an area that needs more work, along with speech-to-text technology, which isn’t as good at understanding children’s voices, particularly if there is a speech impediment. Sorting through the sheer number of programs developed by education technology companies can be a time-consuming challenge for schools. Richard Culatta, CEO of the International Society for Technology in Education, said the nonprofit launched an effort this fall to make it easier for districts to vet what they are buying and ensure it is accessible. Makenzie wishes some of the tools were easier to use. Sometimes a feature will inexplicably be turned off, and she will be without it for a week while the tech team investigates. The challenges can be so cumbersome that some students resist the technology entirely. But Makenzie’s mother, Nadine Gilkison, who works as a technology integration supervisor at Franklin Township Community School Corporation in Indiana, said she sees more promise than downside. In September, her district rolled out chatbots to help special education students in high school. She said teachers, who sometimes struggled to provide students the help they needed, became emotional when they heard about the program.

NEW YORK (AP) — What a wonderful year 2024 has been for investors. U.S. stocks ripped higher and carried the S&P 500 to records as the economy kept growing and the Federal Reserve began cutting interest rates. The year featured many familiar winners, such as Big Tech, which got even bigger as their stock prices kept growing . But it wasn't just Apple, Nvidia and the like. Bitcoin , gold and other investments also drove higher. Here's a look at some of the numbers that defined the year. All are as of Dec. 20. Remember when President Bill Clinton got impeached or when baseball's Mark McGwire hit his 70th home run against the Montreal Expos? That was the last time the U.S. stock market closed out a second straight year with a leap of at least 20%, something the S&P 500 is on track to do again this year. The index has climbed 24.3% so far this year, not including dividends, following last year's spurt of 24.2%. The number of all-time highs the S&P 500 has set so far this year. The first came early, on Jan. 19, when the index capped a two-year comeback from the swoon caused by high inflation and worries that high interest rates instituted by the Federal Reserve to combat it would create a recession. But the index was methodical through the rest of the year, setting a record in every month outside of April and August, according to S&P Dow Jones Indices. The latest came on Dec. 6. The number of times the Federal Reserve has cut its main interest rate this year from a two-decade high, offering some relief to the economy. Expectations for those cuts, along with hopes for more in 2025, were a big reason the U.S. stock market has been so successful this year. The 1 percentage point of cuts, though, is still short of the 1.5 percentage points that many traders were forecasting for 2024 at the start of the year. The Fed disappointed investors in December when it said it may cut rates just two more times in 2025, fewer than it had earlier expected. That’s how many points the Dow Jones Industrial Average rose by the day after Election Day, as investors made bets on what Donald Trump’s return to the White House will mean for the economy and the world . The more widely followed S&P 500 soared 2.5% for its best day in nearly two years. Aside from bitcoin, stocks of banks and smaller winners were also perceived to be big winners. The bump has since diminished amid worries that Trump’s policies could also send inflation higher. The level that bitcoin topped to set a record above $108,000 this past month. It's been climbing as interest rates come down, and it got a particularly big boost following Trump's election. He's turned around and become a fan of crypto, and he's named a former regulator who’s seen as friendly to digital currencies as the next chair of the Securities and Exchange Commission, replacing someone who critics said was overly aggressive in his oversight. Bitcoin was below $17,000 just two years ago following the collapse of crypto exchange FTX. Gold's rise for the year, as it also hit records and had as strong a run as U.S. stocks. Wars around the world have helped drive demand for investments seen as safe, such as gold. It's also benefited from the Fed's cut to interest rates. When bonds are paying less in interest, they pull away fewer potential buyers from gold, which pays investors nothing. It's a favorite number of Elon Musk, and it's also a threshold that Tesla's stock price passed in December as it set a record. The number has a long history among marijuana devotees, and Musk famously said in 2018 that he had secured funding to take Tesla private at $420 per share . Tesla soared this year, up from less than $250 at the start, in part because of expectations that Musk's close relationship with Trump could benefit the company. That's how much revenue Nvidia made in the nine months through Oct. 27, showing how the artificial-intelligence frenzy is creating mountains of cash. Nvidia's chips are driving much of the move into AI, and its revenue through the last nine months catapulted from less than $39 billion the year before. Such growth has boosted Nvidia's worth to more than $3 trillion in total. GameStop’s gain on May 13 after Keith Gill, better known as “Roaring Kitty,” appeared online for the first time in three years to support the video game retailer’s stock, which he helped rocket to unimaginable heights during the “ meme stock craze ” in 2021. Several other meme stocks also jumped following his post in May on the social platform X, including AMC Entertainment. Gill later disclosed a sizeable stake in the online pet products retailer Chewy, but he sold all of his holdings by late October . That's how much the U.S. economy grew, at annualized seasonally adjusted rates, in each of the three first quarters of this year. Such growth blew past what many pessimists were expecting when inflation was topping 9% in the summer of 2022. The fear was that the medicine prescribed by the Fed to beat high inflation — high interest rates — would create a recession. Households at the lower end of the income spectrum in particular are feeling pain now, as they contend with still-high prices. But the overall economy has remained remarkably resilient. This is the vacancy rate for U.S. office buildings — an all-time high — through the first three quarters of 2024, according to data from Moody's. The fact the rate held steady for most of the year was something of a win for office building owners, given that it had marched up steadily from 16.8% in the fourth quarter of 2019. Demand for office space weakened as the pandemic led to the popularization of remote work. That's the total number of previously occupied homes sold nationally through the first 11 months of 2024. Sales would have to surge 20% year-over-year in December for 2024's home sales to match the 4.09 million existing homes sold in 2023, a nearly 30-year low. The U.S. housing market has been in a sales slump dating back to 2022, when mortgage rates began to climb from pandemic-era lows. A shortage of homes for sale and elevated mortgage rates have discouraged many would-be homebuyers.For Makenzie Gilkison, spelling is such a struggle that a word like rhinoceros might come out as “rineanswsaurs” or sarcastic as “srkastik.” The 14-year-old from suburban Indianapolis can sound out words, but her dyslexia makes the process so draining that she often struggles with comprehension. “I just assumed I was stupid,” she recalled of her early grade school years.
