Photons are massless quantum particles that form light. They travel at incredible speeds and interact with various forms of matter. The emission of photons from atoms and molecules can lead to an unlimited number of interactions and possibilities. A new study from the University of Birmingham (UoB) researchers presents a model that explains the interaction between photons and their emitter. Using the calculations from their model, the study authors also created a visual representation of a photon. “Our calculations enabled us to convert a seemingly insolvable problem into something that can be computed. And, almost as a by-product of the model, we were able to produce this image of a photon, something that hasn’t been seen before in physics,” Dr. Benjamin Yuen, first author of the study and a professor at UoB, said . The significance of photons in the quantum world In 1905, Albert Einstein first proposed that light is also made of particles, and in 1926, American chemist Gilbert Newton Lewis coined the term “photon” for such particles. Even after 100 years, scientists still don’t know how a photon actually looks and interacts with different elements of our environment. This is because these particles travel at the speed of light and don’t have a fixed position or a trajectory. While scientists have developed techniques to observe and manipulate photons, such as through experiments involving light detectors or using advanced equipment like high-speed cameras and particle accelerators — these methods only measure or visualize the effects of photons rather than the photons themselves. However, understanding a photon’s geometry, shape, and interactions with matter is crucial to gaining deeper insights into the science that governs the quantum world. For instance, a photon’s wave-particle duality governs how it interacts with matter, enabling phenomena like absorption, emission, and scattering. Similarly, an idea about their shape could enhance the precision of quantum technologies such as quantum photonics, communication, and cryptography. What promise does the new model hold? The mathematical model from the UoB team employs pseudomode expansion, a technique in quantum optics that simplifies studying how light interacts with matter in complex environments, like photonic crystals. Instead of modeling the whole environment in detail, this approach uses a few simplified modes (pseudomodes) to represent the environment’s main effects on the system. This makes the analysis easier while still capturing the important interactions. The model successfully explains the interaction between photons and different quantum emitters (QEs), such as atoms, quantum dots (nanometers-scale particles that act like artificial atoms), and fluorescent molecules. However, it doesn’t stop here; it also sheds light on both the near-field and far-field energies resulting from such interaction. “This work helps us to increase our understanding of the energy exchange between light and matter, and secondly to better understand how light radiates into its nearby and distant surroundings,” Yuen said. “Lots of this information had previously been thought of as just ‘noise’ – but there’s so much information within it that we can now make sense of, and make use of. By understanding this, we set the foundations to be able to engineer light-matter interactions for future applications, such as better sensors, improved photovoltaic energy cells, or quantum computing,” he concluded. The study is published in the journal Physical Review Letters .Malik Nabers: Giants Were 'Soft as F--k' in Bucs Loss; I'm 'Tired of Losing'

Mark Young, Woolery’s friend and podcast cohost, shared the news on X on Saturday. “It is with a broken heart that I tell you that my dear brother @chuckwoolery has just passed away,” Young wrote. “Life will not be the same without him. RIP, brother.” Young told TMZ he was at Woolery’s home in Texas when the former TV host reported not feeling well and went to lie down. When Young checked in later, Woolery was having trouble breathing, and despite a 911 call, Woolery died shortly thereafter. Woolery was born on March 16, 1941, in Ashland, Kentucky, to a business owner and a homemaker, according to The Hollywood Reporter . After stints at the University of Kentucky, in the U.S. Navy, and at Morehead State University, Woolery moved to Nashville to start a music career. He and singer Elkin “Bubba” Fowler formed the psychedelic pop duo The Avant-Garde, and their song “Naturally Stoned” peaked at No. 40 on the Billboard Hot 100 in 1968. Lorimar Television/ Everett Collection A singing performance on The Merv Griffin Show led Woolery to audition for a new game show, originally titled Shopper’s Bazaar , that Merv Griffin was developing at the time. After some tinkering, Wheel of Fortune debuted on NBC on January 6, 1975. Griffin earned a Daytime Emmy for his Wheel work and hosted the show until 1981, when a salary dispute led producers to replace him with Pat Sajak . Woolery moved on with a job hosting the syndicated dating game show Love Connection from 1983 to 1994, pulling in 4.5 million viewers a day at one point. He also emceed the game show Scrabble from 1984 to 1990, and between the two shows, he was earning $1 million a year by 1986, as People reported at the time. Woolery also hosted the game show Greed on Fox from 1999 to 2000 and Lingo on Game Show Network from 2002 to 2007. In recent years, Woolery stoked controversy with his political views, posting a tweet that sparked antisemitism accusations in 2017 and then claiming in 2020 that “everyone [was] lying” about the coronavirus pandemic , as Newsweek reported. He also argued that minorities didn’t need civil rights, according to the Associated Press . Woolery was married four times, and his ex-wives included actor Jo Ann Pflug. He had eight children and stepchildren, per THR . More Headlines:
OpenAI, Artificial Intelligence company and maker of popular chatbot ChatGPT, has officially announced its reasons for transitioning into a for-profit organization, lays out plans. The company via a post on its website noted that the significant shift in its corporate structure was necessitated to ensure the long-term success of its mission, which is to ensure that Artificial Intelligence (AI) benefits all of humanity. This transition involves restructuring OpenAl’s existing for-profit arm into a Delaware Public Benefit Corporation (PBC), designed to balance the interests of shareholders, stakeholders, and the broader public. The move reflects the organization’s evolving priorities, focusing on sustainable operations, robust fundraising capabilities, and a renewed commitment to its mission.

OpenAl was founded in 2015 as a non-profit research lab with the ambitious goal of advancing Artificial intelligence in ways most likely to benefit humanity. In its early years, the AI startup operated without commercial revenue, relying on donations and grants to support its work. However, as it became clear that building AGI required massive computational resources and capital, the organization recognized the need for a new approach. “ Our stated goal was advancing digital intelligence in the way most likely to benefit humanity as a whole, unconstrained by a need to generate financial return.” A non-profit structure seemed fitting, and we raised donations in various forms including cash ($137M, less than a third of which was from Elon) and compute credits and discounts ($1.8M from Amazon and $50M or more from each of Azure and Google Cloud)”, the company wrote. In 2019, OpenAl introduced a unique hybrid structure: a for-profit entity controlled by the non-profit, designed to raise the substantial capital necessary to pursue AGI research while ensuring that profits would flow back to support the non-profit’s mission. This structure facilitated significant investments, including an initial round of over $100 million and a $1 billion partnership with Microsoft. Over the past decade, OpenAl has transformed from a research lab to a pioneering technology company. The launch of ChatGPT in 2022 brought Al into the hands of millions, showcasing the potential of large language models in everyday life. Today, over 300 million people use OpenAl’s products weekly for learning, productivity, and more. Recent advancements, including the o-series models introduced in 2024, have demonstrated new reasoning capabilities that further the path toward AGI. Meanwhile, OpenAl’s influence has extended beyond its products, driving innovation across the Al ecosystem and inspiring other organizations to advance Al safety and accessibility. As OpenAl moves into 2025, the need for significant additional capital has become clear. The Board estimates that hundreds of billions of dollars will be required to develop the infrastructure, compute, and talent necessary for the AGI economy. To attract this level of investment, the organization needs to simplify its structure, making it more appealing to conventional investors. The new plan involves converting OpenAl’s for-profit arm into a Delaware Public Benefit Corporation. This structure, already adopted by many mission-driven organizations, ensures that OpenAl’s decisions will balance profit motives with its commitment to benefiting humanity. Under the proposed structure, the non-profit arm will remain a cornerstone of OpenAl’s mission. The non-profit will retain significant shares in the newly formed PBC, valued by independent financial advisors, providing it with unprecedented resources to pursue charitable initiatives. These initiatives will focus on areas such as healthcare, education, and science, furthering the goal of ensuring Al benefits everyone. OpenAl’s mission is no longer confined to building a single AGI system, Instead, it envisions a continuous journey of contributing to the development of a new Al-powered economy. By evolving its structure, OpenAl aims to lead this transformation while ensuring that the benefits of Artificial Intelligence are widely shared. With this transition, OpenAl is poised to become more than a lab or startup, it is set to emerge as a sustainable, enduring organization committed to advancing Al’s capability, safety, and positive impact on the world.

Lucknow, Nov 24 (PTI) Electoral politics is hard as the momentum shifts ever so quickly, more so in a politically sensitive state like Uttar Pradesh, where the results of the byelections in nine assembly seats have repositioned the ruling BJP in the pole position after a blip in the June 2024 Lok Sabha polls. Having put in the hard yards with multiple rallies across all nine by-poll seats and assigning himself the responsibility of a difficult seat like Katehari in Ambedkarnagar that BJP won after three decades, Chief Minister Yogi Adityanath's stock has skyrocketed to the days when the BJP won a consecutive term in UP in 2022. Adityanath literally set the narrative for the bypolls in August itself with slogans like 'batenge toh katenge (divided we perish)' that were cleverly tailored to reinforce the Hindu unity pitch and resonated right through the mini polls. "For a long time, Samajwadi Party's politics revolved around its 'MY' factor that was meant to denote a particular community and caste. The BJP has changed that with a new 'MY' approach. This 'MY' factor means Modi-Yogi and these two leaders are changing the political discourse with their development narrative, and this by-poll again showed the effectiveness of Yogi ji," UP BJP spokesman Manish Shukla told PTI. The party won six seats out of nine while ally RLD got one. Adityanath's 'batoge toh katoge' slogan made a huge impression was evident in the BJP’s win in the Muslim-majority Kundarki seat in Moradabad. Here, the party had not won in three decades but this time voters consolidated behind BJP’s Ramveer Singh, the lone Hindu among 11 Muslims in the fray. “The SP took Muslims for granted and we went about telling the voters about SP leaders’ claim that virtually anyone on their party’s symbol would win. "Eventually they realised that despite being unfairly demonised by our opponents, only BJP could get them out of the vote bank trap and of course our leadership helped,” Ramveer said. The importance of Kundarki win was such that it even found a mention in Prime Minister Narendra Modi’s speech at the BJP office in Delhi after the BJP-led-NDA’s spectacular win in Maharashtra on Saturday evening. “What it means is that while BJP vote bank consolidated, the SP’s trusted Muslim vote bank that had voted for the party in big numbers both in 2022 UP polls as well as in 2024 Lok Sabha polls disintegrated. Brand Yogi has found a boost while Akhilesh Yadav has some work to do,” a senior BJP leader told PTI. Even in its family bastion of Karhal seat in Mainpuri, which SP chief Akhilesh Yadav had himself won by an impressive margin of around 67000 votes in 2002 UP polls, the SP’s vote bank dipped as party candidate and Akhilesh’s nephew Tej Pratap Yadav won against Anujesh Yadav, also a distant relative of Akhilesh, by about 14000 votes. The SP had alleged massive irregularities in voting and on its complaint the EC had suspended seven police officials in UP. In Sishamau, Kanpur, the only other seat the SP won in the bypolls, the margin was even lesser – about 8000 odd – making it evident the main opposition party had lost the momentum gained after 2024 Lok Sabha poll results. Back then the SP had won 37 seats against BJP’s 33 in UP but the momentum, it appears, has quickly swung back in BJP’s favour. Meerapur assembly seat in Muzaffarnagar in west UP was another seat that had a sizeable Muslim presence. RLD had won the seat in 2022 UP polls when it was in alliance with SP, and has succeeded in retaining it after joining hands with the BJP. "The RLD has a dedicated vote bank comprising all sections of society and people's belief in our leader Jayant Chaudhary showed again with a landslide win," RLD leader Rohit Agarwal told PTI. The Congress, which announced support for SP, didn’t contest the polls and though senior leaders on both sides said “all is well” with the alliance, at the local level discordant notes were heard. These concerns primarily revolved around a lack of ground-level coordination; defeating the very purpose of coordination committees that were set up on October 25 to ensure that. “There is nothing wrong with the alliance. The Congress helped us. The reason for the reverses was mainly due to rampant and blatant misuse of official machinery and the people would make BJP realise this in 2027 UP polls when SP comes to power,” Samajwadi Party’s national secretary Arvind Singh ‘Gope’ told PTI. The BSP, led by four-time former UP chief minister Mayawati, suffered maximum embarrassment as its candidate badly lost the polls, opening the party again to the charge of being a ‘vote katva (vote cutter)’. On Sunday Mayawati after alleging irregularities declared that her party won’t contest any more bypolls – an announcement that meant little in the face of yet another political loss and party leadership’s inability to arrest the slide. “The BJP contested the polls as one unit unlike the opposition that was besieged with internal conflicts," Shukla said. “What can one say about BSP? We all know that it has been the ‘B’ team of BJP and this election too proved that as it contested the election not to win but to dent the chances of the INDIA bloc,” Congress secretary Shahnawaz Alam said.
