  • Indian Scientists Produce Most Detailed 3D Atlas of the Human Brainstem
    by BeauHD on 14/07/2026 at 11:00 am

    Scientists at the Indian Institute of Technology, Madras (IIT-M) have created what they describe as the world's most detailed 3D cellular atlas of the human brainstem, linking whole-brain MRI views to individual neurons across more than 500 tissue sections. The free online atlas, called Anchor, could help researchers better understand diseases such as Alzheimer's, Parkinson's, stroke, and SIDS by showing how healthy and diseased brain tissue differs cell by cell. The BBC reports: Built from high-resolution microscope images rather than costlier molecular techniques, it creates a detailed three-dimensional map of the brainstem, identifying more than 200 clusters of brain cells and nerve pathways. Eight chemical markers help distinguish different cell types, producing one of the clearest pictures yet of this vital, but poorly, understood part of the brain. The brainstem occupies only a sliver of the brain, yet it keeps people alive. It links the brain to the spinal cord and controls breathing, heartbeat, sleep, wakefulness and movement. [...] Users can zoom from the whole brainstem seen on MRI down to individual neurons while maintaining their precise spatial relationships. The researchers have made the atlas freely available online, hoping it becomes a reference tool for neuroscientists, neurologists and neurosurgeons worldwide. Its applications could also extend well beyond anatomy. By comparing healthy brainstem maps with diseased tissue, scientists may better understand disorders ranging from Parkinson's disease and stroke to Alzheimer's disease and sudden infant death syndrome (SIDS). More precise maps could also help neurosurgeons navigate one of the brain's most delicate regions with greater confidence. Read more of this story at Slashdot.

  • Scientists Find Sugar Deep In Our Galaxy
    by BeauHD on 14/07/2026 at 7:05 am

    Astronomers have detected erythrulose, a sugar found in raspberries and self-tanners, in a gas cloud near the center of the Milky Way. While not essential for life itself, the molecule can convert into a form thought to be important for life's origins, adding evidence that key prebiotic ingredients may be widespread across the galaxy. The Associated Press reports: Using two dish-shaped radio telescopes in Spain, researchers collected data from a large gas cloud near the center of the Milky Way. They identified the sugar in gas form by comparing telescope signals to samples in the lab. It's the latest kind of sugar detected in space -- in a region crossed by NASA's twin Voyager, the farthest spacecraft to ever travel from Earth. Scientists have found interesting chemistry in our galaxy, including building blocks for genetic material and parts of the cell. They spotted a cousin to table sugar near the center of the Milky Way about 25 years ago, and black grains from asteroid Bennu retrieved by NASA's Osiris-Rex spacecraft yielded other sugars, including a key DNA ingredient. The latest sugar isn't essential for life, but can easily convert to a form that's thought to be crucial to kick-starting life on Earth. And it's one of the most complex sugars spotted so far, said astrophysicist Erika Hamden with the University of Arizona. The results were published in the journal Nature Astronomy.

  • Over 200 Economists Say 'We Must Act Now' On AI's Economic Impact
    by BeauHD on 14/07/2026 at 3:30 am

    An anonymous reader quotes a report from the Associated Press: Hundreds of economists say in an open letter that institutions "must act now" to address how artificial intelligence could transform the economy and could put many people out of work. The statement released Monday was signed by top economists, along with computer scientists and some executives at tech companies including Anthropic, Google and OpenAI. "AI may become radically more powerful over the next 10 years," says the letter organized by Stanford University's digital economy lab. "This could drive an unprecedented transformation of our economy, larger than the Industrial Revolution, but unfolding over a vastly shorter time frame. It could bring risks, including large-scale job displacement, as well as opportunities such as major gains in living standards." The letter, which has only four sentences, says leaders must "build the incentives, guardrails, and institutions needed to steer AI in a direction that complements humans and benefits society." The Stanford lab says the letter has so far been signed by more than 200 economists and AI researchers, including 16 winners of a Nobel Prize. "We must be intentional and make collective, democratic choices, rather than letting market forces play out and risking leaving most citizens behind," wrote computer scientist and AI pioneer Yoshua Bengio, who was also among the signatories. He said it "it is highly plausible that AI will drastically transform our economies." Other signatories include Google CEO Eric Schmidt, LinkedIn cofounder Reid Hoffman, and Nobel laureates Joseph Stiglitz, Daron Acemonglu, and Simon Johnson. Read more of this story at Slashdot.

  • Microsoft Promises To Fix Search With Major Windows 11 Overhaul
    by BeauHD on 13/07/2026 at 11:00 pm

    Microsoft is overhauling Windows 11 search to prioritize local apps, files, and settings over web results while removing ads, promotions, MSN/Bing clutter, and other distractions. "You've have been asking for search that is faster, more relevant, and easier to use -- whether you're opening an app, finding a file, or changing a setting," Microsoft says in a new blog post. "Because the Windows Search Box is where many people start, we focused first on making results more dependable, easier to scan, and clearer before you click." Windows Central reports: The company is highlighting several key improvements, including clearer results that does a better job at showing why a search result is appearing when a query has been typed, alongside prioritizing local results before reaching out to the web. Search is also getting better at handling things like typos, which should help surface the right results even when the user misspells an app or file. The search home pane will no longer show MSN or Bing content, and promotional content and ads will no longer appear in search results. These upgrades are now rolling out to Windows Insiders in the Experimental Channel, and are expected to roll out to all Windows 11 users later this year. Insiders may not see the changes right away as they are rolling out in waves. The full list of changes can be found here. Read more of this story at Slashdot.

  • US Government Warns That Russia State Hackers Are Coming After Your Router
    by BeauHD on 13/07/2026 at 10:00 pm

    CISA and allied governments are warning users to secure their routers as Russian state-backed hackers continue compromising the devices and turning them into proxy nodes to disguise attacks against critical infrastructure. The advisory urges users to disable outdated SNMP versions, use strong passwords, update firmware, and turn off unnecessary router services to reduce the risk of being swept into these botnets. Ars Technica reports: "Russian Federal Security Service (FSB) Center 16 cyber actors continue to exploit poorly configured and vulnerable networking devices worldwide, opportunistically compromising multiple critical infrastructure sector networks," the Cybersecurity and Infrastructure Security Agency said Monday. The hacking groups are tracked under various names, including Berserk Bear, Energetic Bear, Crouching Yeti, Dragonfly, Ghost Blizzard, and Static Tundra. The advisory was co-issued by governments from around the world, including Australia, Denmark, New Zealand, and the UK. The primary means of compromise the agency warned about was hackers scanning IP ranges with active Simple Network Management Protocol (SNMP) agents that accept common or default authentication credentials. These scans are run by the very sorts of router botnets the actors are trying to enroll the targeted device in. By sending malicious traffic from spoofed addresses, the hackers can use the SNMP agent on poorly configured routers to run malware. SNMP allows users to collect and organize information about managed networking devices or to modify that information to change device behavior. With control of a device, the hackers then use it as an exit node when probing or attacking targets in the communications, defense, energy, financial services, and government sectors. By funneling the malicious traffic through a benign-appearing device on a trustworthy IP address, the attackers are able to lower the chances of getting blocked by firewalls and other security defenses. Monday's advisory made no mention of identical operations carried out in recent years by China. So-called residential proxies are also a go-to tool used by financially motivated criminal hackers to obscure their true IP address. In many cases, these sorts of proxies are made up of millions of streaming devices that are sold with preloaded malware. Read more of this story at Slashdot.

  • German Firm Files For Insolvency After Cybercriminals Shut Down Production For 6 Weeks
    by BeauHD on 13/07/2026 at 9:12 pm

    German textile firm ZEGO has filed for insolvency and is blaming a March cyberattack that shut down production for nearly six weeks. "ZEGO's filing adds another name to the short but growing list of companies that say a digital break-in was commercially fatal to their business," reports The Register. From the report: In a notice to customers and suppliers, the organization said it had exhausted every available option before seeking insolvency protection. Managing director Johannes Zenglein described the filing as "one of the most difficult steps in our company's 37-year history." "The cyberattack of March 29, 2026, however, impacted our company to an extent that we could not fully compensate for despite our best efforts," Zenglein wrote. "The consequences resulted in a production outage of nearly six weeks and significant financial strain. These effects ultimately impacted our financial situation so severely that filing for insolvency became necessary." ZEGO did not disclose what kind of attack it suffered, whether ransomware was involved, who was behind it, or whether customer or employee data was compromised. What it has made clear is that the operational disruption alone was enough to push the business beyond the point of recovery. ZEGO said insolvency proceedings have now been initiated, but insisted the filing does not necessarily spell the end of the business. It said it plans to keep production running while administrators attempt to restructure the business, preserve jobs, and keep customers and suppliers on board. Read more of this story at Slashdot.
