    Quic-test: an open tool for testing QUIC, BBRv3, and FEC under real-world network conditions

    1+ min ago (679+ words) This article was prepared as part of the CloudBridge Research project focused on optimizing network protocols (BBRv3, MASQUE, FEC, QUIC). Video demo of quic-test When we began studying the behavior of QUIC, BBRv3, and Forward Error Correction in real networks " from Wi-Fi to mobile networks and regional backbones " we ran into a simple problem: there were almost no tools capable of accurately reproducing real-world network conditions. There was no comprehensive QUIC tester with charts, channel profiles, FEC, BBRv3 support, TUI, and Prometheus metrics. So we built quic-test " an open tool we use inside CloudBridge Research for all experiments. And now we share it with the community, universities, and engineers. A fully open laboratory environment for analyzing the behavior of QUIC, BBRv3, and FEC in real networks. Not a simulator, but a real engineering instrument " all our research is based on measurements collected with it....

    Songbirds swap colorful plumage genes across species lines among their evolutionary neighbors

    3+ min ago (1014+ words) People typically think about evolution as a linear process where, within a species, the classic adage of "survival of the fittest" is constantly at play. New DNA mutations arise and get passed from parents to offspring. If any genetic changes prove to be beneficial, they might give those young a survival edge. Over the great span of time " through the slow closing of a land bridge here or the rise of a mountain range there " species eventually split. They go on evolving slowly along their own trajectories with their own unique mutations. That's the process that over the past 3.5 billion years has created the millions of branches on the evolutionary tree of life. However, new genome sequencing data reveals an unexpected twist to this long evolutionary story. It turns out that the boundaries between species on their own branches of…...

    Princeton expands recycling program for food scraps, adding five new drop-off sites ⋆ Princeton, NJ local news %

    6+ min ago (265+ words) Princeton residents will have more places to ditch their food waste instead of sending it to landfills, as the town this week doubled down on its growing food-scraps recycling program with five new drop-off sites. The new bins are located at Griggs Farm, Thanet Circle, Westminster Choir College, Mercer Road, and at the former Princeton First Aid & Rescue Squad building on North Harrison Street. The program, launched in October 2023, allows residents to drop off household food waste instead of placing it in the trash. Food scraps in landfills produce methane, a greenhouse gas. According to the municipality, nearly 500 households participate in the program, which has diverted more than 50 tons of material from landfills and now averages about 1,500 pounds of food waste collected per week. Princeton officials said the expansion was funded through a federal Composting and Food Waste Reduction grant....

    How to Transform Your Company Into an AI Powerhouse

    7+ min ago (643+ words) A practical framework for leaders who want to win the future AI isn't the next chapter of digital transformation. It's the operating system of the modern company. Related: Why Entrepreneurs Need to Adapt and Utilize the Power of AI Right Now Most companies think that becoming an AI company means adopting the right AI model or platform. But the real shift is deeper. AI isn't just software; it's intelligence woven into every workflow, every role, every decision. When we look at the companies succeeding with AI today, the pattern is clear: Step 1: Start with outcomes, not algorithms Leaders don't ask, "What AI tools should we buy?" They ask, "Which business outcomes matter most this quarter?" Faster sales cycles, lower operating costs, better customer experiences and higher employee productivity. Build AI around these outcomes, not around technology hype. Step 2: Empower every…...

    MAIA’s Ateganosine Surges Ahead with Breakthrough Momentum as Pivotal Phase 3 Trial Initiates

    7+ min ago (267+ words) We believe that MAIA has positioned itself at the forefront of a new scientific category in oncology. To our knowledge, Ateganosine remains the only direct telomere-targeting anticancer agent currently in clinical development anywhere'a key distinction in a treatment landscape where most therapeutic advances build upon established mechanisms rather than introduce entirely new ones. According to management, statistical assessments of the Phase 3 trial points to a very high probability of technical success for regulatory approval of ateganosine. The U.S. Food and Drug Administration (FDA) has granted Fast Track designation for ateganosine for the treatment of NSCLC. A Dual Mechanism Unlike Existing Therapies Ateganosine works through a dual mechanism of action that we believe differentiates it from existing chemotherapies, targeted agents, and immunotherapies. First, the molecule is selectively incorporated into cancer-cell telomeres by telomerase, an enzyme active in more than 80% of human cancers....

    3I/ATLAS Is 'Strange Because It Was Forged Under Alien Conditions', Experts Say

    8+ min ago (260+ words) The third time, as the saying goes, is the charm. Only the third confirmed object ever seen passing through our solar system from another star system, the interstellar visitor known as 3I/ATLAS is now ... Hubble's fresh look on November 30 captured a compact bluish coma and faint jets of material. The Perseverance rover on the surface of Mars managed a faint telescopic glimpse as the comet passed just 19 million miles away. Deep-space asteroid explorers, the Psyche and Lucy spacecraft, grabbed long-distance images to help refine its path. In a groundbreaking first, the Japanese-led XRISM X-ray observatory detected a faint X-ray glow around 3I/ATLAS, providing a new window into how it interacts with the solar wind. The closest approach to Earth for this celestial visitor is on December 19, 2025, when it will safely pass by at a distance of about 1.8 astronomical units, or…...
