UC Riverside doctoral student awarded prestigious DOE fellowship

Ryan Milton will conduct AI-based nuclear physics research at SLAC National Accelerator Laboratory

2026-02-05

(Press-News.org) RIVERSIDE, Calif. -- Ryan Milton, a fourth-year doctoral student in nuclear physics at UC Riverside, has been awarded a U.S. Department of Energy’s Office of Science Graduate Student Research (SCGSR) Fellowship. The fellowship, which provides a $3,600 monthly stipend for one year, will support his research at the SLAC National Accelerator Laboratory, part of Stanford University.

“My research focuses on developing and deploying AI tools to understand the behavior of protons and neutrons in nuclei,” Milton said. “Each proton and neutron is made of quarks, but we still don’t fully understand how those quarks behave within a nucleus.”

To address this problem, Milton will develop and apply novel AI-based “unbinned” analysis methods that allow scientists to extract as much information as possible from experimental data.

“I’ll be working with Dr. Ben Nachman at SLAC to further develop this method and apply it to experiments at Jefferson Lab and to simulations for the future Electron-Ion Collider, which is currently under construction at Brookhaven National Lab.”

Miguel Arratia, Milton’s advisor and an assistant professor of physics and astronomy at UCR, said Milton is on a path to becoming a leader in artificial intelligence.

“Ryan has already built software tools that make cutting-edge AI more accessible to the physics community, and his recent first-author paper on research supported by our NSF cyberinfrastructure award shows real impact,” Arratia said. “With this fellowship, Ryan will be able to take his skills to the next level at SLAC, working closely with one of the top experts in the field.”

Milton emphasized the broader impact of his AI work.

“AI is transforming how the world operates, and it is impacting our understanding of fundamental science,” he said. “With the development of our AI unbinned analysis, we will be creating useful methods for all of science. Scientists will be able to make measurements with unprecedented precision, and thereby improve our understanding of the universe.”

Milton’s passion for the field began during his undergraduate studies at UCLA.

“I joined a research group almost by chance after taking a class with a professor whose work in nuclear physics fascinated me,” he said. “I quickly became interested in the computational side of the field. It’s exciting to use cutting-edge and fast-evolving tools to make discoveries in nuclear physics and contribute towards the impressive experiments at Brookhaven and Jefferson labs.”

Arratia said Milton has deployed advanced artificial intelligence/machine learning (AI/ML) models that have had “a real impact on the design of our future experiments.”

“That work was supported by our Department of Energy AI grant, which enabled Ryan and other students to work at Livermore and Berkeley National Laboratories,” he said. “Now, this new fellowship will help us build a strong connection with SLAC. Overall, Ryan’s fellowship reflects the continued success of our group in developing and deploying AI/ML tools to the physical sciences.”

Milton expressed excitement at being part of a field that explores the fundamental building blocks of matter through sophisticated techniques.

“We’re constantly pushing the boundaries of what we know about the universe, and that’s a pretty inspiring thing to do every day,” he said. “The SCGSR fellowship gives me a fantastic opportunity at SLAC to learn about and create AI methods that will improve our understanding of the physical world.”

UMD team finds E. coli, other pathogens in Potomac River after sewage spill

2026-02-05

COLLEGE PARK, Md. – Following one of the largest sewage spills in U.S. history, University of Maryland researchers have detected high levels of fecal-related bacteria and disease-causing pathogens in the Potomac River, raising urgent public health concerns and underscoring the risks posed by aging sewer infrastructure. Water sample results collected at the site by researchers show high levels of E. coli are present along with Staphylococcus aureus (the bacteria that causes Staph infections). An antibiotic-resistant strain of S. aureus, MRSA, was also identified at the site of the sewage overflow. “People coming into contact with the impacted ...

New vaccine platform promotes rare protective B cells

2026-02-05

Cambridge, MA – A longstanding goal of immunotherapies and vaccine research is to induce antibodies in humans that neutralize deadly viruses such as HIV and influenza. Of particular interest are antibodies that are “broadly neutralizing,” meaning they can in principle eliminate multiple strains of a virus such as HIV, which mutates rapidly to evade the human immune system. Researchers at MIT and the Scripps Research Institute have now developed a vaccine that generates a significant population of rare precursor B cells that are capable of evolving to produce broadly neutralizing antibodies. Expanding these cells is the first step toward a successful HIV ...

Apes share human ability to imagine

2026-02-05

In a series of tea party-like experiments, Johns Hopkins University researchers demonstrate for the first time that apes can use their imagination and play pretend, an ability thought to be uniquely human. Consistently and robustly across three experiments, one bonobo engaged with cups of imaginary juice and bowls of pretend grapes, challenging long-held assumptions about the abilities of animals. The findings suggest that the capacity to understand pretend objects is within the cognitive potential of, at least, an enculturated ape, and likely dates back 6 to 9 million years, to our common evolutionary ...

Major step toward a quantum-secure internet demonstrated over city-scale distance

2026-02-05

Marking a significant step toward a quantum-secure internet, researchers have demonstrated device-independent quantum key distribution over optical fibers spanning 100 kilometers (km). The findings show that cryptographic security can be guaranteed with this method, at the metropolitan scale – which represents a much greater distance than previous efforts – and help to close the gap between proof-of-principle quantum network experiments and real-world applications. Quantum key distribution (QKD) is a leading application of quantum technologies, enabling ultra-secure digital communications. Early forms of QKD derive security using trusted ...

Increasing toxicity trends impede progress in global pesticide reduction commitments

2026-02-05

Around the world, the total toxicity and ecological harm from agricultural pesticides are rising, despite recent United Nations commitments to halve pesticide use and risks by 2030. The findings establish a global, toxicity-weighted baseline for pesticide use and identify a subset of pesticides, crops, and countries driving the most biodiversity impacts. The widespread use of agricultural pesticides is a growing threat to global biodiversity. To address this concern, the 15th United Nations Biodiversity Conference set the goal of halving pesticide use and risk by 2030 and recently adopted a new global indicator – total applied toxicity (TAT) – that captures not just ...

Methane jump wasn’t just emissions — the atmosphere (temporarily) stopped breaking it down

2026-02-05

A temporary weakening of the atmosphere’s chemical capacity to break down methane, combined with elevated emissions from tropical wetlands, drove the sharp increase in atmospheric methane observed in 2020 to 2021, according to a new study. Methane (CH4) is a significant contributor to atmospheric warming. In the early 2020s, the amount of atmospheric CH4 grew faster than ever before observed, peaking at 16.2 parts per billion per year (ppb yr-1), before declining to 8.6 ppb yr-1 in 2023. It’s hypothesized that this surge was driven by a combination of increased natural emissions and a coincident decrease in the atmosphere’s oxidizing capacity, namely, fewer OH ...

Flexible governance for biological data is needed to reduce AI’s biosecurity risks

2026-02-05

In a Policy Forum, Doni Bloomfield and colleagues discuss the need for expanded – yet tailored and flexible – governance for the biological data used to develop powerful artificial intelligence (AI) models. Rapidly advancing AI systems trained on biological data have enabled researchers to design new molecules, predict protein structure and function, and probe vast and highly complex biological datasets for novel insights that could greatly expand our understanding of nature and human health. However, these same tools could also be misused for dangerous purposes, such as designing harmful pathogens or generating genetic ...

Increasing pesticide toxicity threatens UN goal of global biodiversity protection by 2030

2026-02-05

At the 15th UN Biodiversity Conference (COP15) in Montreal, Canada, in 2022, nations committed to reducing the risks associated with pesticide use in agriculture by 50% by 2030. A new study by a research team from RPTUKaiserslautern-Landau, published in the journal Science, reveals that this global target is now under serious threat. Using a novel analytical method, the researchers assessed trends in pesticide toxicity worldwide and found that current trajectories fall far short of the 2030 goal. The study concludes that immediate, coordinated ...

How “invisible” vaccine scaffolding boosts HIV immune response

2026-02-05

LA JOLLA, CA—One of the biggest hurdles in developing an HIV vaccine is coaxing the body to produce the right kind of immune cells and antibodies. In most vaccines, HIV proteins are attached to a larger protein scaffolding that mimics a virus. Then, a person’s immune system produces a range of antibodies that recognize different bits of those proteins. Often, however, some of those antibodies react not to HIV itself—but to the scaffold used to deliver the vaccine. Now, researchers at Scripps Research and the Massachusetts Institute of Technology (MIT) have developed a new kind ...

Study reveals the extent of rare earthquakes in deep layer below Earth’s crust

2026-02-05

Stanford researchers have created the first-ever global map of a rare earthquake type that occurs not in Earth’s crust but in our planet’s mantle, the layer sandwiched between the thin crust and Earth’s molten core. The new map will help scientists learn more about the mechanics of mantle earthquakes, in turn opening a window into the complexities and triggers for all earthquakes. As reported in a study published Feb. 5 in Science, continental mantle earthquakes occur worldwide but are clustered regionally, particularly in the Himalayas in southern Asia and the ...
