This paper investigates two fundamental descriptors of data, i.e., density distribution versus mass distribution, in the context of clustering. Density distribution has been the de facto descriptor of data distribution since the introduction of statistics. We show that density distribution has its fundamental limitation -- high-density bias, irrespective of the algorithms used to perform clustering. Existing density-based clustering algorithms have employed different algorithmic means to counter the effect of the high-density bias with some success, but the fundamental limitation of using density distribution remains an obstacle to discovering clusters of arbitrary shapes, sizes and densities. Using the mass distribution as a better foundation, we propose a new algorithm which maximizes the total mass of all clusters, called mass-maximization clustering (MMC). The algorithm can be easily changed to maximize the total density of all clusters in order to examine the fundamental limitation of using density distribution versus mass distribution. The key advantage of the MMC over the density-maximization clustering is that the maximization is conducted without a bias towards dense clusters.

No one promoted that idea more persistently than Swiss author Erich von Däniken, often described as the father of ancient alien archaeology. Von Däniken, who died this month aged 90, argued that extraterrestrial visitors played a direct role in helping ancient Egyptians construct monuments that would otherwise have been impossible. In his 1968 bestseller'Chariots of the Gods,' he claimed alien'astronauts' visited early civilizations, including the ancient Egyptians and Mayans, and shared advanced technology.

Environment Animals Wildlife Fish'Walking sharks' lay eggs without breaking a sweat Breakthroughs, discoveries, and DIY tips sent six days a week. Being pregnant and giving birth is hard work for any species--but epaulette sharks () might disagree. These fish and a number of other species are known as " walking sharks " for their ability to traverse both the seafloor and land with their fins. Epaulette sharks' energy use didn't change during their reproduction cycle, as described in a study recently published in the journal . "Reproduction is the ultimate investment you are literally building new life from scratch," Jodie Rummer, a marine biologist at James Cook University and co-author of the recent study, said in a university statement .

The new time for the symbolic timepiece, which ticks closer to midnight as we approach annihilation, will be revealed on Tuesday, January 27. Since last year, the clock has sat at 89 seconds to midnight - the latest time in its 78-year history. However, experts have told the Daily Mail they now expect the Doomsday Clock to move even closer to midnight . While the Doomsday Clock was initially created to track the risk of nuclear war between Russia and America, the world now faces a far more diverse array of threats.

Increased use of AI and automation in businesses is increasingly replacing'low-complexity, transactional roles', the survey showed. Increased use of AI and automation in businesses is increasingly replacing'low-complexity, transactional roles', the survey showed. Survey reveals'mismatched AI expectations' between views of employers and staff over impact on careers More than a quarter (27%) of UK workers are worried their jobs could disappear in the next five years as a result of AI, according to a survey of thousands of employees. Two-thirds (66%) of UK employers reported having invested in AI in the past 12 months, according to the international recruitment company Randstad's annual review of the world of work, while more than half (56%) of workers said more companies were encouraging the use of AI tools in the workplace. This was leading to "mismatched AI expectations" between the views of employees and their employers over the impact of AI on jobs, according to Randstad's poll of 27,000 workers and 1,225 organisations across 35 countries.

Altman's campaigning for his company coincides with its use of enormous present resources to serve an imagined future OpenAI CEO Sam Altman poses during the Artificial Intelligence (AI) Action Summit, at the Grand Palais, in Paris, on February 11, 2025. Sam Altman has claimed over the years that the advancement of AI could solve climate change, cure cancer, create a benevolent superintelligence beyond human comprehension, provide a tutor for every student, take over nearly half of the tasks in the economy and create what he calls "universal extreme wealth". In order to bring about his utopian future, Altman is demanding enormous resources from the present. As CEO of OpenAI, the world's most valuable privately owned company, he has in recent months announced plans for $1tn of investment into datacenters and struck multibillion-dollar deals with several chipmakers. If completed, the datacenters are expected to use more power than entire European nations .

A thin, watery layer coating the surface of ice is what makes it slick. The reason we can gracefully glide on an ice-skating rink or clumsily slip on an icy sidewalk is that the surface of ice is coated by a thin watery layer. Scientists generally agree that this lubricating, liquidlike layer is what makes ice slippery. They disagree, though, about why the layer forms. Three main theories about the phenomenon have been debated over the past two centuries.

You don't need to Ernest Shackleton yourself to reap the benefits of cold plunging. A calm, controlled ice bath is key. Depending on your disposition, a minute in an ice bath can feel like agony or ecstasy. Perhaps you wince at the thought of stepping foot in an ice bath, or maybe you're an experienced cold plunger who can't get enough of the endorphin-releasing sensation. There are many ways to access cold water therapy from having a cold shower, to submerging your body in a dedicated cold plunge pool.

Policymakers are being urged to nudge companies to put checks in place on powerful AI tools. Policymakers are being urged to nudge companies to put checks in place on powerful AI tools. Tech could lose its social acceptance unless it makes people's lives better - and trade unions want an urgent conversation "Who wouldn't want a robot to watch over your kids?" Elon Musk asked Davos delegates last week, as he looked forward with enthusiasm to a world with "more robots than people". Not me, thanks: children need the human connection - the love - that gives life meaning. As he works towards launching SpaceX on to the stock market, in perhaps the biggest ever such share sale, the world's richest man has every incentive to talk big.
