Alta Resource Technologies Expands Series Seed Funding to $10M to Scale Protein-Based Critical Minerals Technology
BOULDER, Colo.--(BUSINESS WIRE)-- Alta Resource Technologies, a pioneer in using advanced biochemistry to transform mineral separation, today announced that it has expanded its Series Seed funding to $10 million with the close of an additional $4.4 million investment. The Seed 2 investment was co-led by DCVC and Voyager Ventures with participation from Orion Industrial Ventures and In-Q-Tel (IQT), the not-for-profit strategic investor for the U.S. national security community and America's allies.
Securing resilient, low-impact sources of critical minerals is no longer optional for America and its allies—it's a strategic imperative.
The new capital will accelerate development and commercialization of Alta's breakthrough platform, which uses engineered proteins to selectively bind to and separate critical minerals—including rare earth elements like neodymium and dysprosium—from low-grade ores and complex waste streams. The approach promises to dramatically reduce the environmental impact of mineral extraction while helping to secure domestic supply chains for essential materials used in advanced electronics, clean energy technologies, and modern defense systems.
The investment comes at a pivotal moment for critical-mineral supply chains, many of which are dominated by China. This concentration of control has raised alarms about economic and national security. Responding to the growing urgency around supply chain resilience, the White House issued an executive order in March 2025 aimed at boosting domestic mineral production and reducing U.S. reliance on fragile foreign supply chains. Alta's technology offers a timely and scalable solution: a low-impact way to extract high-purity critical minerals from unconventional and previously uneconomic sources.
'Securing resilient, low-impact sources of critical minerals is no longer optional for America and its allies—it's a strategic imperative,' said Nathan Ratledge, PhD, Alta's Co-Founder and CEO. 'Washington is beginning to respond with the kind of wartime urgency this moment demands, and Alta's technology is uniquely positioned to deliver. Our protein-based platform gives the U.S. a scalable way to tap into unconventional mineral resources right here at home, while slashing both costs and environmental impact.'
Alta's platform is based on protein engineering breakthroughs developed in partnership with Lawrence Livermore National Laboratory and researchers at Pennsylvania State University. By customizing proteins to bind selectively to individual elements—even at low concentrations in complex mixtures—Alta's solution offers far greater precision than conventional separation methods. The result is a step-change in the efficiency, sustainability, and economics of processing rare earths and other critical materials.
The company will use the new funding to expand its technical team, advance commercial pilots, and extend its technology to a broader range of metal targets and feedstocks, including mine tailings, waste streams, and end-of-life products.
'Alta exemplifies how deep technology can address critical global challenges while creating enormous commercial value,' said James Hardiman, General Partner at DCVC. 'We're increasing our investment because Alta has assembled an exceptional team and demonstrated remarkable progress in developing a revolutionary platform for critical mineral separation that can help secure America's technological future.'
'Alta's protein-based platform demonstrates the promise of engineering biology to address significant national security challenges. We are excited about supporting Alta's technological innovation to diversify the nation's sources of critical minerals and advance domestic processing capabilities,' said Dr. Jessica Dymond, VP, Technology at IQT.
The new funding brings Alta's total Series Seed investment to $10 million, building on the initial funding announced earlier this year. In addition to private capital, Alta has received grant support from federal partners and the State of Colorado.

Angel or Adversary: Deep Instinct Research Highlights the Double-Edged Sword of AI in Cybersecurity
NEW YORK--(BUSINESS WIRE)-- Deep Instinct, the preemptive data security company built on the first and only AI-based deep learning framework for cybersecurity, today released the sixth edition of its Voice of SecOps Report, which delves into the growing influence of AI in business, with a focus on its impact on Security Operations (SecOps). While AI adoption is accelerating, the findings uncover a more complex reality: security teams are limited by knowledge gaps, inconsistent implementation, and mounting operational pressures as they face an increasingly treacherous, AI-driven threat landscape. The research, ' Cybersecurity & AI: Promises, Pitfalls – and Prevention Paradise,' found that nearly three-quarters (72%) of organizations have revised their cybersecurity strategies over the past year due to AI, and a whopping 86% have increased their use of AI within SecOps. Despite the investments, two-thirds of respondents were confused about fundamental AI definitions, with 38% unable to differentiate between machine learning and deep learning – signaling an alarming knowledge gap in the industry. Additional key findings from the report include the following: AI-Powered Cyber Threats Drive a Focus on Prevention As cybercriminals build and adopt AI tools, the nature and scale of attacks have drastically evolved and expanded. Nearly half (46%) of organizations experienced an uptick in targeted phishing attacks, while 43% reported deepfake impersonation attempts. Attacks on local or cloud storage were also a growing concern, cited as a top risk by 83% of respondents, second only to phishing (84%). In response to these AI-powered attacks, 82% of organizations say they have shifted toward a prevention-first security strategy, with 64% noting a direct push from the C-suite to adopt more proactive defense measures. Benefits of AI in Cybersecurity Roles Are Clear, Yet It Unexpectedly Contributes to Burnout SecOps teams appear to be reaping the benefits of AI, with 76% stating it makes their roles easier while saving security teams an average of 12 hours per week on manual processes. However, while GenAI may be simplifying some aspects of SecOps workloads, nearly 70% of security professionals believe AI also contributes to burnout. Regulatory complexity adds another layer of strain, with 32% citing difficulties in keeping up with increasing AI-related policies, and an additional 37% fearing AI-related regulations are a financial penalty waiting to happen. Preemptive Data Security: The New Imperative In the face of mounting threats, operational burnout, and AI confusion, preemptive data security – a subset of Gartner's recently introduced preemptive cybersecurity market category – offers a definitive path forward. By harnessing the power of deep learning to prevent threats before they execute, organizations will reduce risk, ease the burden on SecOps teams, and stay ahead of relentless adversaries. 'The traditional 'detect and respond' cybersecurity model is broken – it's reactive, expensive, and no match for AI-powered threats,' said Lane Bess, CEO of Deep Instinct. 'To win this fight, cybersecurity teams must shift from chasing threats to preventing them. Preemptive data security – powered by deep learning, the most advanced form of AI – is the only way for SecOps teams to regain control and stay ahead of adversaries.' To get the full report and download past Voice of SecOps reports, please visit s. Then register for our webinar, Cybersecurity & AI: Promises, Pitfalls – and Prevention Paradise (2025 Voice of SecOps Research), to learn about the top findings from this year's report.

CHICAGO--(BUSINESS WIRE)--Leading international medical research company, MEDSIR announced today the positive results of the TUXEDO-3 trial at the American Society of Clinical Oncology (ASCO) Annual Meeting 2025. This phase II study funded by Daiichi Sankyo and Merck, known as MSD outside of the United States and Canada, evaluates the efficacy and safety of patritumab deruxtecan (HER3-DXd) in patients with active brain metastases and leptomeningeal disease, serious complications associated with advanced stages of the cancer. "This study represents a significant advancement in our understanding of how to treat brain metastases and leptomeningeal disease" - Dr. Matthias Preusser. Share The study was carried out to evaluate HER3-DXd in patients with metastatic breast cancer (mBC) and advanced non-small cell lung cancer (aNSCLC) with active brain metastases, and patients with leptomeningeal disease from solid tumors. This is an antibody-drug conjugate to target HER3, a protein receptor found on the surface of cancer cells in brain metastases. HER3-DXd is an investigational agent consisting of a fully human anti-HER3 IgG1 monoclonal antibody attached to a number of topoisomerase I inhibitor payloads (an exatecan derivative, DXd) via tetrapeptide-based cleavable linkers. The DXd ADC Technology payload causes tumor DNA damage, killing cancer cells within and surrounding the tumor microenvironment The study showed promising results, which were presented today in an oral session. Results from the leptomeningeal cohort have been simultaneously published in the renowned journal Nature Medicine due to its potential benefit in patients with a high unmet medical need. In patients with breast cancer and brain metastases, intracranial responses were observed across all breast cancer subtypes, including luminal, HER2-positive, and triple-negative. A NEW HOPE FOR DIFFICULT-TO-TREAT METASTASES 'This study represents a significant advancement in our understanding of how to treat brain metastases and leptomeningeal disease, and we are hopeful that our findings will pave the way for new, effective therapies for these patients,' stated Dr. Matthias Preusser, MD, Medical Oncologist and Head of the Clinical Division of Oncology, Medical University of Vienna and Principal Investigator of TUXEDO-3. Dr. Rupert Bartsch, MD, PhD, Consultant Hematology and Medical Oncology, Medical University of Vienna, added: 'Brain metastases and leptomeningeal disease represent severe complications in cancer, leading to increased morbidity and mortality, and HER3-DXd could be a promising therapeutic alternative for these patients.' MEDSIR's trial DEMETHER, an international, phase II trial exploring the maintenance of trastuzumab and pertuzumab following trastuzumab deruxtecan as induction treatment for HER2-positive recurrent metastatic breast cancer patients, was mentioned during today's Discussion of LBA1008. DEMETHER's strategy is to optimize the sequence to increase patients' progression free survival (PFS) while improving their quality of life. The relevance of this mention highlighted the ability of MEDSIR for anticipating patients' needs and designing strategical trials to keep on pushing the barriers of clinical research. MEDSIR active presence at the ASCO Annual Meeting 2025 reinforces its leadership in excellence-driven oncology research and highlights its focus on addressing unmet needs in cancer treatment, with the aim of not leaving any patient left behind.
