(Press-News.org) Delta.g, a UK-based quantum technology company, has raised £4.6 million in an oversubscribed seed round to accelerate the development and deployment of its gravity sensing platform. The round was led by Serendipity Capital with participation from NSSIF, and existing investor SCVC.
Quantum sensing has emerged as one of the first quantum technologies with the greatest potential to deliver immediate real-world impact, enabling breakthrough advances in subsurface imaging, navigation, and environmental monitoring. Yet across infrastructure, energy, and defence, access to high-resolution spatial data remains limited. Without reliable spatial intelligence, organisations are forced to operate with incomplete information, driving up risk, cost, and delays. Delta.g’s platform directly tackles these gaps, delivering quantum sensors that offer a step-change in precision, portability, and reliability over existing technologies. Spun out of the University of Birmingham, Delta.g’s technology was developed at the UK Quantum Technology hub for Sensors and Timing. The proprietary technology, engineered for real-world conditions and early trials is now owned by Delta.g and has shown its value across infrastructure, transportation, and dual-use cases.
Tony Lowe, CEO of Delta.g, said: "We’re thrilled by the strong investor support at this early stage. This raise is more than capital; it’s a vote of confidence in our mission to make quantum sensing operational. We’re building the tools to see what others can’t, in places that matter most, from hidden sinkholes to critical infrastructure. With this funding, we’re accelerating our roadmap to deliver smaller and more nimble field-ready systems."
Spatial intelligence is becoming a critical layer of 21st-century decision-making. From detecting sinkholes to mapping old mine workings and enabling GPS-free navigation, reliable gravity-based data gives governments and industries the ability to anticipate risks and plan with confidence. Today’s tools often deliver patchy or misleading results. The consequences can be costly: in the UK alone, poor subsurface data results in billions of pounds in annual losses across infrastructure and utilities, while resilience gaps leave sectors such as defence and energy vulnerable to avoidable risk.
Rob Jesudason, CEO and Founder of Serendipity Capital, said, Rob Jesudason, CEO and Founder of Serendipity Capital, said, ‘Delta.g serves as yet another proof point of UK leadership in quantum and dual use technologies. Our investment reflects our firm belief that the multi-year investment by the UK Government in quantum technologies combined with the UK's world class scientific talent, Universities and research institutions is producing companies that have the potential to obtain global leadership. Delta.g's scientific co-founders Prof. Mike Holynski, Dr Jonathan Winch and Dr Andrew Lamb are truly world class in their field. We look forward to working with Delta.g and helping it to realise its groundbreaking potential.’
John Williams, SCVC General Partner, said: “Delta.g is a perfect example of our thesis in action - backing transformative science early, building the company around it, and supporting the leadership to turn breakthrough ideas into impact. This milestone reflects years of hard work by an exceptional team.”
An NSSIF Spokesperson said, “We're delighted to support Delta.g’s quantum sensing technology that has a range of potential dual-use applications. As a strategic investor, we're looking forward to supporting the next stage of the technology development and company growth.
With the capital, Delta.g will:
Expand its technical team and manufacturing capacity
Deliver field systems through pilot deployments across key government and commercial partners
Advance its data and analytics platform to integrate quantum-grade geospatial insights into decision-making at scale, creating the “Google Maps” for the subsurface.

New mechanisms for bacterial motility and DNA transfer between bacteria decoded
2025-09-26
Bacteria are constantly moving by help of motility organs called flagella or pili to colonize new niches. Also, bacteria can exchange information, like “speaking to each other”, and thus acquire new abilities through the exchange of DNA materials. These motility organs play important roles in DNA uptake to exchange genetic information between different bacteria, allowing what’s so-called genomic plasticity. Therefore, bacterial motility organs contribute to bacterial pathogenicity, colonizing ...
Lightweight UAV object detection with reparameterized convolutions and shallow fusion networks
2025-09-26
Remote sensing object detection is a rapidly growing field in artificial intelligence, playing a critical role in advancing the use of Unmanned Aerial Vehicles (UAVs) for real-world applications such as disaster response, urban planning, and environmental monitoring. Yet, designing models that balance both high accuracy and fast, lightweight performance remains a challenge. UAVs often capture images where objects appear in different sizes, angles, and lighting conditions, all while operating on devices with limited computing power. This creates the need for innovative ...
Protecting the protectors: as measles cases surge, how can we help healthcare workers get vaccinated?
2025-09-26
In recent years, measles has made a resurgence globally. In England, 2024 saw the highest number of confirmed measles cases since 2012, resulting in the declaration of a national incident. One reason for this is falling vaccination rates, prompted — to some extent — by the success of established measles vaccination programmes, which has reduced public awareness of the contagiousness and potentially serious complications of measles.
Measles is often erroneously thought to be a childhood disease. Yet approximately one-third of the 2,911 cases confirmed in England in 2024, and six of the seven measles-related deaths since 2000, were ...
Superlattice blotting constructs ordered mesoporous carbon with high nickel single atom support for efficient electrocatalysis

Yuanyuan Wang and Wenlei Zhu's group at Nanjing University, China, and Yuehe Lin at Washington State University, USA, recently reported the development of a three-dimensional ordered mesoporous carbon skeleton with Ni single atom support using the superlattice blotting strategy for efficient electrocatalytic hydrogen production. Firstly, they derived an ordered mesoporous framework based on finite element simulation, which is of great significance for promoting uniform gas distribution, stabilizing the gas-liquid-solid interface of nanoscale hydrophilic surfaces, and enhancing mass transfer kinetics. Then, the proposed superlattice blotting ...
Beyond adsorption: Dalian scientists uncover biochar’s hidden superpower—direct pollutant destruction
2025-09-26
The Biochar Myth-Buster
We’ve all heard the story: biochar cleans water by adsorbing pollutants—trapping them like a sponge. Or, in fancier setups, it acts as a catalyst to help oxidants like hydrogen peroxide break down toxins. But Dr. Gao’s team asked a bold question: What if biochar can degrade pollutants all by itself? Turns out—it can. And it’s been doing it quietly all along.
The Electron Ninja: Biochar’s Secret Power
The secret lies in electron transfer—a natural ability of biochar that’s been overlooked for years. Think of it like this: instead of just catching a bad guy (adsorption), biochar can now take them ...
Turning a problem into a resource: Scientists transform biomass tar into high-value carbon materials
2025-09-26
A sticky, toxic by-product that has long plagued renewable energy production may soon become a valuable resource, according to a new review published in Biochar.
When biomass such as crop residues, wood, or other organic matter is heated to produce clean energy and biochar, it also generates a thick liquid known as bio-tar. This tar easily clogs pipelines, damages equipment, and poses environmental risks if released into the atmosphere. For decades, researchers have sought ways to eliminate or neutralize it.
Now, a team led by scientists at the Chinese Academy of Agricultural Sciences argues that instead of being treated as waste, bio-tar can be converted into “bio-carbon”—a ...
New study reveals hidden “electron highways” that power underground chemistry and pollution cleanup
2025-09-26
Beneath our feet, an invisible world of electron exchanges quietly drives the chemistry that sustains ecosystems, controls water quality, and even determines the fate of pollutants. A new review published in Environmental and Biogeochemical Processes sheds light on how electrons travel through soils and sediments across surprisingly long distances—sometimes spanning centimeters to meters—reshaping our understanding of underground environments and offering new strategies for pollution cleanup.
Redox reactions—the give-and-take of electrons between chemical species—are fundamental to life and environmental stability. They govern how nutrients cycle, ...
International healthcare workers report on war related injuries among civilians in Gaza
2025-09-25
A British led study published by The BMJ today provides detailed data on the pattern and severity of traumatic injuries and medical conditions seen by international healthcare workers deployed to Gaza during the ongoing military invasion.
Healthcare workers describe “unusually severe” traumatic injuries including complex blast injuries, firearm related injuries, and severe burns. Many respondents with previous experience of conflicts reported that the pattern and severity of injuries in Gaza were greater than those they had encountered in previous warzones.
It’s thought to be the first study ...
