  • Ozempic-style drugs treat type 1 diabetes, not only type 2, study finds

    Ozempic-style drugs treat type 1 diabetes, not only type 2, study finds

    Semaglutide, the active ingredient in Ozempic, and other drugs in the same class have revolutionized the treatment of obesity and type 2 diabetes. Now, a clinical trial suggests the medicines can treat type 1 diabetes, as well.

    The trial results, published June 23 in the journal NEJM Evidence, suggest semaglutide can improve blood sugar levels and induce weight loss in people with type 1, potentially introducing a new drug that could be used along with insulin to manage the disease.

  • ESA’s Biomass Satellite Reveals Mother Earth’s Hidden Forest Structures and Carbon Stores

    ESA’s Biomass Satellite Reveals Mother Earth’s Hidden Forest Structures and Carbon Stores

    Biomass refers to the total mass of living plant material in an area, typically measured as dry weight. Forest biomass includes the trunks, branches, leaves, and roots of trees. Biomass is a key indicator of how much carbon is being stored in forests, since trees absorb carbon dioxide from the atmosphere and store it in their tissues. Tracking biomass helps scientists better understand carbon fluxes, assess the impact of deforestation and forest degradation, and improve climate change models. This information also supports international agreements aimed at reducing carbon emissions, such as the Paris Agreement.

    “These first images are nothing short of spectacular — and they’re only a mere glimpse of what is still to come,” said Michael Fehringer, ESA’s Biomass Project Manager. “As is routine, we’re still in the commissioning phase, fine-tuning the satellite to ensure it delivers the highest quality data for scientists to accurately determine how much carbon is stored in the world’s forests.”

    ESA leaders celebrated the achievement and the collaborative effort behind the mission. “It was extremely emotional because it was the work of hundreds of people,” said Simonetta Cheli, ESA’s Director of Earth Observation Programmes, in an interview with Space.com. “It’s very symbolic of the effort behind the scenes and the potential that this mission has.”

    One of the first images captures a vibrant region in Bolivia, where rainforest blends into riverine floodplains. This area has experienced extensive deforestation driven largely by agricultural expansion. In the false-color image, green represents rainforest, red indicates forested wetlands and floodplains, and blue-purple highlights grasslands. Cutting through the terrain is the dark, snaking line of the Beni River, one of the last major undammed rivers in the region. “It shows the beauty of our Earth and what we can do to protect it,” Cheli said during a press conference at the Vienna symposium.

    A comparison of the same Bolivian region, imaged by both Biomass and Copernicus Sentinel-2, underscores the mission’s unique capabilities. While Sentinel-2 offers natural-color imagery of surface features, Biomass uses P-band radar to penetrate the canopy and reveal the forest’s vertical structure—essential for accurately measuring biomass and carbon content.

    Other early images further showcase the satellite’s global reach and scientific potential. Over northern Brazil, Biomass recorded its first image, highlighting diverse Amazonian terrain. Red and pink shades mark wetlands and floodplains, while green depicts denser, higher forests to the north. This level of detail offers new ways to monitor forest health in some of the world’s most ecologically vital and remote regions.

    In Indonesia, an image of the mountainous Halmahera rainforest captures the rugged topography shaped by volcanic activity, including the still-active Mount Gamkonora. Despite the dense vegetation, Biomass can reveal subsurface features such as volcanic slopes and forest floor contours, demonstrating its value for both ecological and geological studies.

    From Africa’s Congo Basin, the satellite offers a view of Gabon, where the Ivindo River winds through pristine rainforest. The radar imagery brings clarity to one of the most carbon-dense forest regions in the world, aiding conservation efforts in a region under increasing pressure.

    In a striking contrast, an image of the Sahara Desert in Chad reveals hidden ancient riverbeds and geological features beneath the sand. Biomass’s radar can see up to five meters below the desert surface, opening new frontiers in understanding past climates and identifying groundwater resources in arid environments like the Tibesti Mountains region.

    The mission also reaches into polar extremes. A view of Antarctica’s Nimrod Glacier, alongside the Transantarctic Mountains, showcases how Biomass can peer into the ice itself—providing insights into internal glacial structures and movement. This could prove vital for tracking ice sheet stability and predicting future sea-level rise.

    While these initial images are still undergoing calibration and are not yet ready for scientific analysis, they confirm that the satellite is functioning as intended—and potentially exceeding expectations. With a planned five-year mission, Biomass will provide regular, global forest coverage, offering vital data for climate research, conservation planning, and international carbon accounting.

    As the satellite moves into full operations, scientists anticipate a flood of high-quality data that could reshape how we observe and protect Earth’s ecosystems—especially its forests, which remain among the planet’s most critical carbon sinks.

  • Prepare to Share All Your Pics With Meta If You Turn On Facebook’s New AI Photo Tool

    Prepare to Share All Your Pics With Meta If You Turn On Facebook’s New AI Photo Tool

    There’s good news and bad news: The bad news is that Meta’s continued development of generative AI has led it to add a privacy nightmare setting to its Facebook app. The good news is that, in a big departure from Meta’s status quo, you have control over whether you participate.

    It’s all about whether the company and its AI get access to your camera roll and all the pictures there, even the ones you haven’t posted anywhere.

    Meta, Facebook’s parent company, has been trying to keep up with AI heavyweights for the past few years in an ultracompetitive race to make the most advanced AI models. Meta distinguished itself by adding its AI to its social media apps, including Instagram, Facebook, WhatsApp and Messenger. Nowadays, most of us who use those apps have to interact with Meta AI, even if we don’t want to. 

    AI Atlas

    The company also uses the social media posts that its adult users publicly share to train its AI. There is no way to opt out of training, though European users can object to their data being used thanks to more stringent privacy laws protecting them. For those of us who are concerned about AI systems eating up the content we share online, it’s been a nonstop headache.

    So it’s not totally surprising to see this feature on Facebook. It’s called camera roll cloud processing, and Facebook says it’s a way to get more creative help when you share photos and videos. It pulls from your newer pictures, from the last 30 days or so, and recommends the best options, makes AI edits or entirely reimagines your photos with AI. It can also pull from your older photos for themed compilations like travel highlights, monthly recaps and birthday and special event content. You also get more ways to sort your photos and videos by topic and suggestions from Meta about the best photos to share.

    Before you opt in, you need to understand the privacy implications.

    Meta’s AI terms and how to access camera roll cloud processing

    When you allow camera roll cloud processing, Meta can “automatically upload your photos and videos to our cloud so that we can create personalized creative ideas for you.” This is not the same as allowing Meta access to your camera roll so you can post photos and videos you took. If you enable this additional setting, Meta can upload your content to its cloud “on a regular basis to create ideas for you with machine learning and AI models.” Meaning Meta will have continual access to your photos, even if you don’t post them on Facebook or post the newly created suggestions.

    A Meta spokesperson said, “We’re exploring ways to make content sharing easier for people on Facebook by testing suggestions of ready-to-share and curated content from a person’s camera roll. These suggestions are opt-in only and only shown to you — unless you decide to share them — and can be turned off at any time. Camera roll media may be used to improve these suggestions, but are not used to improve AI models in this test.”

    The mobile app help page says that enabling this feature means you agree to Meta’s AI terms, and it says your photos won’t be used for advertising targeting. The feature is in early stages of testing for US- and- Canada based users, but it won’t be available for folks who live in Illinois or Texas. Your suggested photo won’t be shared automatically unless you choose to.

    Here’s how to access the setting:

    1. Open the Facebook app and tap Menu at the bottom right corner.
    2. Tap the gear icon in the upper right corner. You can also scroll down to Settings & privacy and then navigate to Settings.
    3. Tap Camera roll sharing suggestions.
    4. Scroll to Get creative ideas made for you by allowing camera roll cloud processing.

    This feature is currently only available on the iPhone or Android mobile apps. If you have this setting enabled but then change your mind, Meta’s help page says it will remove your content from its cloud after 30 days. There’s no way to confirm its removal, though.

  • Google’s fix for Pixel 6A battery overheating issues arrives next week

    Google’s fix for Pixel 6A battery overheating issues arrives next week

    A mandatory update for Google’s mid-range Pixel 6A phones is coming next week that is meant to reduce the risk of the battery overheating on some devices. According to a support page post, Google is issuing the mandatory Android 16 update starting July 8 to all Pixel 6A devices. However, only users with “Impacted Devices” will see any effect on their battery.

    Google says affected users will get a notification when the phone has completed 375 cycles, giving them a heads-up that the new battery management features will be activated soon. Once these management tools are in effect, the battery won’t last as long between charges.

    According to Google, users may see other changes, “like reduced charging performance or short-term changes to how the battery-level indicator on your phone shows your battery capacity as your phone learns its revised battery capacity.” It’s not clear why some Pixel 6A phones are affected and others aren’t, but if yours is, Google is offering free battery replacement — you can check here to see if you’re eligible.

    The company has already dealt with a similar issue on the Pixel 4A, offering owners a free battery replacement or a $100 credit towards a new phone. It currently has an extended repair program for battery swelling issues on the Pixel 7A.

  • New evidence that some supernovae may be a “double detonation”

    New evidence that some supernovae may be a “double detonation”

    In other cases, another member of the system will go on to form a second white dwarf. If gravitational instabilities bring these two objects together, then their collision will create a single object with a much higher mass. This will also restart fusion, leading to an explosion.

    We have found evidence for both of these events happening. However, there are some questions about whether they happen often enough to explain the frequency of type Ia supernovae that we see. Both mechanisms require stars of sufficient mass orbiting within a reasonably close distance for either mass transfer or a collision to occur. So, astronomers have been considering other ways of blowing up a white dwarf.

    The most promising option appears to be a double detonation. This can also require the transfer of some helium-rich material from another companion, but it can also occur if the white dwarf ends up with some unfused helium left on its surface. Regardless of how it ends up there, the helium can start fusing if enough of it pools up, or simply if its movement causes a sufficiently high local density in one region. However it happens, once fusion starts, the entire surface of the white dwarf will quickly follow, creating detonation number one.

    That in turn will create compression in the carbon-oxygen portion of the white dwarf, pushing it past the density needed for that to start fusing. Once again, the initiation of fusion heats and compresses nearby material, creating a chain reaction that triggers widespread fusion in the white dwarf, blowing it to pieces as part of detonation two.

    A shell game

    The key thing about this is that it allows the explosion of white dwarfs before they reach a mass sufficient enough to trigger the fusion of their carbon and oxygen. Instead, it can potentially happen any time enough helium gathers on their surface. A double-detonation event would also be very difficult to detect, as the explosions would happen in rapid succession, and the environment in the immediate surroundings of a type Ia supernova is going to be complex and difficult to resolve.

  • Here’s When to See July’s Spectacular Buck Moon, Along With Mars and Venus

    Here’s When to See July’s Spectacular Buck Moon, Along With Mars and Venus

    It’s officially summer, and with that comes the first full moon of the season. July’s full moon — known as the Buck Moon or the Thunder Moon — will light up the night sky on July 10 and be at its fullest going into July 11, reaching peak luminosity at around 4:37 a.m. local time, which is a bit late, but it’ll still be bright for the whole night. 

    According to Stellarium’s sky map, the moon will rise from the southeastern horizon just after sunset in your local time and streak across the sky before setting on the southwestern horizon just before dawn. No matter where you are in the US, you’ll be able to see it virtually all night. 

    Should you not be able to see the moon due to weather or some other reason, you can also soak up a great view anytime from July 8-12 as the moon will be more than 95% full during those days. 

    Why is it called the Buck Moon or Thunder Moon?

    According to The Farmer’s Almanac, July’s full moon actually has several names, including Buck Moon, Thunder Moon, Feather Moulting Moon, and Salmon Moon. These names typically come from Native American and colonial times and were used to describe the moon for the entire month, not just when it’s full. 

    White-tailed deer start growing antlers in March or April as the days start to lengthen. July marks the peak of their antler growth season, hence the name Buck Moon. Thunderstorms are also common in July, which is why it’s also called the Thunder Moon. 

    The other two names are less common, but July marks the time when some species of salmon begin migrating for the mating season, while ducks engage in their annual molting around this time of year as well. 

    Catch a glimpse of Mars and Venus, too

    The moon will be joined in the sky by Mars and Venus during its trip across the sky on July 10. Mars will be visible just after sunset in the western sky before setting. You won’t have long, since it’s scheduled to dip below the horizon before midnight. If you choose to stay up late, Venus will crest the eastern horizon shortly after 2 a.m. local time and be visible until sunrise. 

    Saturn will also be visible in the eastern sky, not far from the moon, but you’ll likely need binoculars or a telescope to see it with the moon’s glow.

    Once the moon finishes its monthly cycle, skygazers can check out the Alpha Capricornids and Southern Delta Aquariids meteor showers, both of which are scheduled to peak during the last few days of July.
