(Press-News.org) Weill Cornell Medicine has received a $5.2 million, initial two-year award from the Advanced Research Projects Agency for Health (ARPA-H) Lymphatic Imaging, Genomics, and pHenotyping Technologies (LIGHT) program to develop a comprehensive and innovative approach to diagnosing lymphatic disease. LIGHT is led by ARPA-H Program Manager Kimberley Steele, M.D., Ph.D.
The lymphatic system is a network of vessels, nodes and organs that drains excess fluid from tissues, filtering out waste and supporting the immune system by producing, activating and transporting infection-fighting cells. When the system is not working properly, fluid accumulates in tissues, a condition called lymphedema, and the body can become more susceptible to infection and tissue damage. However, diagnosis of lymphatic disease is challenging because the vessels are tiny and translucent and the fluid they carry moves slowly, which makes the system difficult to image.
The ARPA-H award funds a project called LANTERN (Lymphatic disease Advancements with Nanotechnology, Translational Epigenetics, and Research in Genetics), led by principal investigator Dr. Lishomwa Ndhlovu, the Herbert J. and Ann L. Siegel Distinguished Professor of Medicine in the Division of Infectious Diseases at Weill Cornell Medicine. LANTERN aims to improve the detection and understanding of lymphatic disease by developing new diagnostic tools. Researchers will use approaches such as large-scale analysis of genetic information, nanotechnology to create molecular fingerprints of the condition, and artificial intelligence to assess data. Early and precise detection of the condition can ultimately lead to better treatment.
“The goal of this program is really trying to make the invisible visible with technology that complements ongoing developments in imaging,” said Dr. Ndhlovu, who is also a professor of immunology in neuroscience at the Feil Family Brain and Mind Research Institute at Weill Cornell Medicine.
What is Lymphatic Disease?
Primary and secondary lymphatic disease affect hundreds of millions of people worldwide, according to the Lymphatic Education and Research Network. Primary lymphatic disease occurs when a person is born with abnormalities in their lymphatic vessels or nodes. Secondary lymphatic disease can occur from infection, chronic disease, trauma, surgery or cancer treatments like radiation. Lymphedema is one of the most common lymphatic diseases.
A better understanding of the lymphatic system is important because many chronic diseases have a lymphatic component, but physicians lack reliable tools to assess the lymphatic system, said Dr. Ndhlovu. Symptoms of lymphatic dysfunction, like swelling, often appear only after the disease has progressed. As a result, underlying chronic conditions can go untreated.
Creating a Diagnostic Toolbox
Dr. Ndhlovu and his colleagues aim to develop a diagnostic toolbox or platform that doctors can use to rapidly and reliably detect lymphatic disease. The toolbox would include biomarkers that provide information about the structure and function of the lymphatic system, the detection of genetic changes and epigenetic changes—or how environmental factors and behaviors alter how genes work—combined with other data.
The team includes collaborators Dr. Daniel Heller, a member of the Molecular Pharmacology Program at Memorial Sloan Kettering Cancer Center (MSK) and a professor in the Weill Cornell Graduate School of Medical Sciences and Dr. Mijin Kim, an assistant professor at Georgia Tech, who are developing advanced detection technologies using nanosensors, or tiny devices that can detect molecular changes in tissues, and artificial intelligence, to analyze information so that doctors can better predict and prevent disease and develop targeted treatment plans.
With collaborators Dr. Babak Mehrara, a plastic and reconstructive surgeon at MSK and professor of surgery (plastic surgery) at Weill Cornell Medicine, and Dr. Stanley G. Rockson, chief of consultative cardiology and the Allan and Tina Neill Professor of Lymphatic Research and Medicine at Stanford Medicine, the researchers will analyze information from existing patient databases as well as lymphatic fluid samples from patients at MSK and Stanford.
Another important part of the program is gathering input from patient advocates who can provide feedback on what types of information is valuable to them and their well-being.
At one point, Dr. Ndhlovu hopes to integrate the new platform with any new imaging modalities of lymphatic disease that researchers develop through the ARPA-H LIGHT program.
“I'm very excited about this opportunity,” Dr. Ndhlovu said. “This field has been a dark hole regarding imaging and diagnostics. The scope of diseases that are impacted by the lymphatic system is remarkable, so any advances in our understanding of lymphatic disease could have an impact across the spectrum of conditions including in our work in infectious diseases research.”

It started with a cat: How 100 years of quantum weirdness powers today’s tech
2026-01-20
A hundred years ago, quantum mechanics was a radical theory that baffled even the brightest minds. Today, it’s the backbone of technologies that shape our lives, from lasers and microchips to quantum computers and secure communications.
In a sweeping new perspective published in Science, Dr. Marlan Scully, a university distinguished professor at Texas A&M University, traces the journey of quantum mechanics from its quirky beginnings to its role in solving some of science’s toughest challenges.
“Quantum mechanics started as a way to explain the behavior of tiny particles,” said Scully, who is also affiliated with Princeton University. “Now ...
McGill researchers identify a range of unexpected chemical contaminants in human milk
2026-01-20
An interdisciplinary team including researchers at McGill University has found a range of unexpected chemical contaminants in human milk samples from Canada and South Africa. The chemicals include traces of pesticides, antimicrobials and additives used in plastics and personal-care products. The findings were published across five papers.
“It is important to note that these chemicals were detected at low concentrations, and we do not fully understand the health effects of many of them. So, despite these findings, breast milk remains ideal for infants, as it has the nutrients infants need ...
Physical therapy research highlights arthritis’ toll on the workforce — and the path forward
2026-01-20
According to new research from the University of Delaware, nearly 40% of American adults ages 18 to 64 with arthritis — almost 10 million people — say the medical condition is limiting their ability to work.
Co-author Daniel White, associate professor of physical therapy at UD, analyzed findings from the 2023 National Health Interview Survey, which was recently published in the journal Arthritis Care & Research.
White says the number is likely much higher than 40%.

Forgetting in infants can be prevented in mice by blocking their brain’s immune cells
2026-01-20
Babies of every species from mouse to human rapidly forget things that happen to them—an effect called infantile amnesia. A type of brain immune cell called microglia might control this type of forgetting in young mice, according to a study published January 20th in the open-access journal PLOS Biology by Erika Stewart, from Trinity College Dublin in Ireland, and colleagues.
Infants and young children are growing rapidly and taking in vast amounts of information as they grow. However, there is a lack of episodic memory from this early period of development ...
Blocking immune cells in the brain can prevent infant forgetting
2026-01-20
Scientists have found that blocking microglia (specialist immune cells in the brain) prevents infant forgetting (“infantile amnesia”) and improves memory in mice, suggesting that microglia may actively manage memory formation and dictate what, and when, we forget.
Infants of many species from mouse to human rapidly forget things that happen to them—a phenomenon called infantile amnesia -- but until now we have known little about how this happens. The new discovery, just published in leading international journal PLOS Biology, now offers strong support ...
AI-driven ultrafast spectrometer-on-a-chip: A revolution in real-time sensing
2026-01-20
For decades, the ability to visualize the chemical composition of materials, whether for diagnosing a disease, assessing food quality, or analyzing pollution, depended on large, expensive laboratory instruments called spectrometers. These devices work by taking light, spreading it out into a rainbow using a prism or grating, and measuring the intensity of each color. The problem is that spreading light requires a long physical path, making the device inherently bulky.
A recent study from the University of California Davis (UC Davis), reported in Advanced Photonics, tackles the challenge of miniaturization, aiming to shrink a lab-grade ...
World enters “era of global water bankruptcy”; UN scientists formally define new post-crisis reality for billions
2026-01-20
UN Headquarters, New York – Amid chronic groundwater depletion, water overallocation, land and soil degradation, deforestation, and pollution, all compounded by global heating, a UN report today declared the dawn of an era of global water bankruptcy, inviting world leaders to facilitate “honest, science-based adaptation to a new reality.”
“Global Water Bankruptcy: Living Beyond Our Hydrological Means in the Post-Crisis Era,” argues that the familiar terms “water stressed” and “water crisis” fail to reflect today’s reality in many places: a post-crisis condition marked by irreversible losses of natural ...
Innovations in spatial imaging could unlock higher wheat yields
2026-01-20
Researchers at the John Innes Centre and the Earlham Institute are pioneering powerful single-cell visualisation techniques that could unlock higher yields of global wheat.
Firmly in their sights is the longstanding question that has perplexed the wheat research community: Why do grains at the bottom of the spike fail to achieve full size compared to those higher up?
Previous studies have analysed wheat tissue in bulk (taking dissected tissue pieces in their entirety), limiting image resolution, and increasing the likelihood of unclear results.

A twitch in time? Quantum collapse models hint at tiny time fluctuations
2026-01-20
Quantum mechanics is rich with paradoxes and contradictions. It describes a microscopic world in which particles exist in a superposition of states—being in multiple places and configurations all at once, defined mathematically by what physicists call a ‘wavefunction.’ But this runs counter to our everyday experience of objects that are either here or there, never both at the same time. Typically, physicists manage this conflict by arguing that, when a quantum system comes into contact with a measuring ...
