  • Nova Launcher Gets a New Owner and Ads
    by BeauHD on 21/01/2026 at 10:40 pm

    Nova Launcher has been acquired by Instabridge, which says it will keep the app maintained but is evaluating ad-supported options for the free version. Android Authority reports: Today, Nova Launcher announced that the Swedish company Instabridge has acquired it from Branch Metrics. Instabridge claims it wants to be a responsible owner of Nova and does not want to reinvent the launcher overnight. However, the launcher still needs a sustainable business model to support ongoing development and maintenance. To this end, Instabridge is exploring different options, including paid tiers and ad-supported options for the free version. The new owners claim that if ads are introduced, Nova Prime will remain ad-free. However, this is misleading, as ads are already here for some users. Last year, the founder and original programmer of Nova Launcher left the company, signaling its "death" as he had been the sole developer working on the launcher for the past year.

  • HAM Radio Operators In Belarus Arrested, Face the Death Penalty
    by BeauHD on 21/01/2026 at 10:02 pm

    An anonymous reader quotes a report from 404 Media: The Belarusian government is threatening three HAM radio operators with the death penalty, detained at least seven people, and has accused them of "intercepting state secrets," according to Belarusian state media, independent media outside of Belarus, and the Belarusian human rights organization Viasna. The arrests are an extreme attack on what is most often a wholesome hobby that has a history of being vilified by authoritarian governments in part because the technology is quite censorship resistant. The detentions were announced last week on Belarusian state TV, which claimed the men were part of a network of more than 50 people participating in the amateur radio hobby and have been accused of both "espionage" and "treason." Authorities there said they seized more than 500 pieces of radio equipment. The men were accused on state TV of using radio to spy on the movement of government planes, though no actual evidence of this has been produced. State TV claimed they were associated with the Belarusian Federation of Radioamateurs and Radiosportsmen (BFRR), a long-running amateur radio club and nonprofit that holds amateur radio competitions, meetups, trainings, and forums. Siarhei Besarab, a Belarusian HAM radio operator, posted a plea for support from others in the r/amateurradio subreddit. "I am writing this because my local community is being systematically liquidated in what I can only describe as a targeted intellectual genocide," Besarab wrote. "I beg you to amplify this signal and help us spread this information. Please show this to any journalist you know, send it to human rights organizations, and share it with your local radio associations." Read more of this story at Slashdot.

  • Ozempic is Reshaping the Fast Food Industry
    by msmash on 21/01/2026 at 9:22 pm

    New research from Cornell University has tracked how households change their spending after someone starts taking GLP-1 medications like Ozempic and Wegovy, and the numbers are material enough to explain why food industry earnings calls keep blaming everything except the obvious culprit. The study analyzed transaction data from 150,000 households linked to survey responses on medication adoption. Households cut grocery spending by 5.3% within six months of a member starting GLP-1s; high-income households cut by 8.2%. Fast food spending fell 8.0%. Savory snacks took the biggest hit at 10.1%, followed by sweets and baked goods. Yogurt was the only category to see a statistically significant increase. As of July 2024, 16.3% of U.S. households had at least one GLP-1 user. Nearly half of adopters reported taking the medication specifically for weight loss rather than diabetes management. About 34% of users discontinue within the sample period, and when they stop, candy and chocolate purchases rise 11.4% above pre-adoption levels.

  • Half of World's CO2 Emissions Come From Just 32 Fossil Fuel Firms, Study Shows
    by msmash on 21/01/2026 at 8:45 pm

    Just 32 fossil fuel companies were responsible for half the global carbon dioxide emissions driving the climate crisis in 2024, down from 36 a year earlier, a report has revealed. The Guardian: Saudi Aramco was the biggest state-controlled polluter and ExxonMobil was the largest investor-owned polluter. Critics accused the leading fossil fuel companies of "sabotaging climate action" and "being on the wrong side of history" but said the emissions data was increasingly being used to hold the companies accountable. State-owned fossil fuel producers made up 17 of the top 20 emitters in the Carbon Majors report, which the authors said underscored the political barriers to tackling global heating. All 17 are controlled by countries that opposed a proposed fossil fuel phaseout at the Cop30 UN climate summit in December, including Saudi Arabia, Russia, China, Iran, the United Arab Emirates and India. More than 80 other nations had backed the phaseout plan. Read more of this story at Slashdot.

  • Adobe Acrobat Now Lets You Edit Files Using Prompts, Generate Podcast Summaries
    by msmash on 21/01/2026 at 8:01 pm

    Adobe has added a suite of AI-powered features to Acrobat that enable users to edit documents through natural language prompts, generate podcast-style audio summaries of their files, and create presentations by pulling content from multiple documents stored in a single workspace. The prompt-based editing supports 12 distinct actions: removing pages, text, comments, and images; finding and replacing words and phrases; and adding e-signatures and passwords. The presentation feature builds on Adobe Spaces, a collaborative file and notes collection the company launched last year. Users can point Acrobat's AI assistant at files in a Space and have it generate an editable pitch deck, then style it using Adobe Express themes and stock imagery. Shared files in Spaces now include AI-generated summaries that cite specific locations in the source document. Users can also choose from preset AI assistant personas -- "analyst," "entertainer," or "instructor" -- or create custom assistants using their own prompts. Read more of this story at Slashdot.

  • The Gold Plating of American Water
    by msmash on 21/01/2026 at 7:22 pm

    The price of water and sewer services for American households has more than doubled since the early 1980s after adjusting for inflation, even though per-capita water use has actually decreased over that period. Households in large cities now spend about $1,300 a year on water and sewer charges, approaching the roughly $1,600 they spend on electricity. The main driver is federal regulation. Since the Clean Water Act of 1972 and the Safe Drinking Water Act of 1974, the U.S. has spent approximately $5 trillion in contemporary dollars fighting water pollution -- about 0.8% of annual GDP across that period. The EPA itself admits that surface water regulations are the one category of environmental rules where estimated costs exceed estimated benefits. New York City was required to build a filtration plant to address two minor parasites in water from its Croton aqueduct. The project took a decade longer than expected and cost $3.2 billion, more than double the original estimate. After the plant opened in 2015, the city's Commissioner of Environmental Protection noted that the water would basically be "the same" to the public. Jefferson County, Alabama, meanwhile, descended into what was then the largest municipal bankruptcy in U.S. history in 2011 after EPA-mandated sewer upgrades pushed its debt from $300 million to over $3 billion.
