International labor migration plays a vital role in supporting families across low- and middle-income countries, often providing a critical source of income for families back home. However, when mothers migrate abroad for work, young children may be left without steady parental care during important developmental stages. While this concern is widely discussed, there has been limited real-world evidence showing how policies that restrict maternal migration affect children’s outcomes.

 

A new study made available online on December 13, 2025, and published in Volume 200 of the World Development journal on April 1, 2026, examines this question by analyzing a migration policy introduced in Sri Lanka in 2013. The policy restricted mothers with children under 5 years of age from migrating overseas for work. By comparing families affected by the policy with those who were not, the researchers assessed its impact on children’s health, education, and household income. The study was led by Associate Professor Takuya Hasebe from Sophia University, Japan, with co-authors Yuma Noritomo from Cornell University, USA, and Bilesha Weeraratne from the Institute of Policy Studies, Sri Lanka.

 

“This study assessed a policy that was actually implemented in Sri Lanka,” says Dr. Hasebe. “We hope that its findings will contribute to ongoing discussions on migration policy in Sri Lanka and other countries.”

 

To inspect the policy’s effects, the researchers used data from Sri Lanka’s Household Income and Expenditure Survey collected between 2009 and 2016. This nationally conducted survey includes detailed information on family structure, income sources, education, and health. The team compared households affected by the policy with similar households that were not affected, both before and after the policy was introduced. This approach allowed them to isolate the effects of the migration restriction from broader economic or social trends.

 

The study focused on households with children between the ages of 2 and 10 years. Key outcomes included children’s hospital admissions and illness-related inpatient stays, as well as educational indicators, such as grade repetition, which refers to a child repeating the same school year.

 

The analysis showed that the policy led to fewer mothers migrating abroad for work and increased the likelihood that mothers remained at home with their young children. This change was associated with clear benefits for children’s well-being. Children in affected households experienced fewer hospital admissions and fewer illness-related inpatient stays, indicating improvements in overall health. Educational outcomes also improved, particularly for older siblings, who were less likely to repeat a school grade.

 

“These improvements can be understood as investments in human capital,” explains Dr.  Hasebe. “The effects are not merely temporary; the accumulation of human capital is likely to have lasting positive impacts on children’s future outcomes.”

 

One common concern about restricting international migration is the potential loss of income from overseas remittances. However, the study found no overall decline in household income. While international payments decreased, this loss was largely offset by increased domestic income support, such as earnings from within the country or transfers from other household members.

 

The findings suggest that policies aimed at keeping mothers with young children at home may offer important social benefits. At the same time, the researchers caution that migration policies are complex and can have multiple effects beyond those captured in this analysis.

 

“Our analysis captures only one aspect of the policy,” Dr. Hasebe notes. “A more comprehensive, multi-dimensional approach will be an important direction for future research.”

 

Overall, by providing rare empirical evidence from a real-world policy intervention, the study adds an important perspective to global debates on migration, family welfare, and child development. It highlights how decisions about labor mobility can shape children’s lives in lasting ways—well beyond short-term economic considerations.

LOS ANGELES — Keck Medicine of USC radiologists use computed tomography (CT) scanners to diagnose and treat patients’ diseases and injuries.  

Recently, however, this advanced technology was put to a far more novel use: examining the bodies of two ancient Egyptian mummies. 

Radiologists conducted full-body CT scans of two Egyptian priests, Nes-Min, circa 330 BCE, and Nes-Hor, circa 190 BCE, whose bodies had been preserved for more than 2,200 years.  

The mummies, along with 3D digital models and 3D prints of select parts of their bodies, will be on display at “Mummies of the World: The Exhibition,” an upcoming exhibit at the California Science Center opening Feb. 7.  

Each mummy was scanned inside the bottom half of its sarcophagus, which weighed approximately 200 pounds each. The mummies were wrapped in linen shrouds, blackened with age. The older mummy, Nes-Min, was draped in a garment of heavily beaded net over his torso and wore several strands of colorful beads.  

A state-of-the-art, 320 slice CT scanner revealed small details of their bodies that humanized the men, including facial features such as eyelids and their lower lips. The images also held clues about their health, life experiences and lifespans that resonate with people today.  

Scans reveal healed injuries, dental issues and other modern-day ailments  

Analysis of the scans showed that the elder of the mummies, Nes-Min, probably suffered from an aching lower back like many modern humans. His spine showed a collapsed lumbar or lower back vertebrae likely due to natural aging and wear and tear.  

He was buried with several artifacts, representing several scarab beetles and a fish.  

Nes-Hor’s scan revealed dental issues and a severely deteriorated hip, and that he was older at the time of death than Nes-Min.  

"These scans provide a treasure trove of information made possible by Keck Medicine’s access to the latest in high-level scanning, coupled with the team’s expertise,” said Summer Decker, PhD, who leads 3D imaging for Keck Medicine and serves as director of the USC Center for Innovation in Medical Visualization with the Keck School of Medicine of USC.  

“These mummies were scanned previously, but due to advancements in scanning technology, the results are much more detailed and extensive than ever before,” said Decker, who oversaw the mummy scans and visualization analysis. “The high-resolution images have revealed things that were previously unknown and helped create a picture of what their lives were like.” 

After scanning the mummies, Decker and her colleague, Jonathan Ford, PhD, used the scans to create 3D digital models of the men. They also printed out life-size reproductions of the men’s spines, skulls and hips, as well as artifacts found with Nes-Min, using medical-grade 3D printers.  

“Mummies have long been a mystery. Seeing beneath the surface to reveal the specific lived experience of individuals is incredibly exciting,” said anthropologist Diane Perlov, PhD, senior vice president for special projects at the California Science Center. “This modern scientific technology offers us a powerful window into the world of ancient people and past civilizations that might otherwise be lost.” 

Keck Medicine’s 3D technology brings organs to life  

Keck Medicine’s 3D visualization and printing technologies used on the mummies allow for surgeons to turn medical imaging, such as a CT or MRI scan, into physical reproductions of a patient’s liver, heart, pelvis or other structure.  

The scans first create hundreds of detailed 3D cross-sectional images (or “slices”), then 3D visualization experts digitally “stack” the images together to form 3D digital models. These models can then be analyzed, measured or used to print on high-resolution medical-grade 3D printers, meaning that the prints can be used in surgery and are safe to touch and potentially be implanted in a patient.  

Surgeons then use these prints to better visualize and understand a patient’s complex medical condition or practice the best surgical solution before entering the operating room. 

“Through 3D visualization, modeling and printing, clinicians like surgeons can accurately measure hard-to-detect tumors, examine the intricate structure of a patient’s heart or liver or determine how best to repair a shoulder or hip,” said Decker. “They walk into the operating room with a much better idea of what they are facing and how they will approach surgery. With these advanced technologies, we can create custom treatments and solutions for our patients, which may lead to improved outcomes.”  

Patients may also benefit from holding a replica of their own organ in their hand, Decker continued. “They gain a new understanding of what their condition is and how it will be treated,” she said.  

Keck Medicine has access to almost two dozen 3D printers housed in the USC Center for Innovation in Medical Visualization. 

About the exhibit  

“Mummies of the World: The Exhibition” first debuted at the California Science Center in 2010. After touring the globe, the exhibition returns to Los Angeles for its closing venue with a new selection of mummies never seen before in Los Angeles.

Clinical data gaps keeping life-saving antibiotics from children




Murdoch Childrens Research Institute






Life-saving antibiotics that could treat severe infections in babies and children aren’t accessible due to a lack of data around safety and dosage, new research shows.

Two wide sweeping reviews, led by Murdoch Children’s Research Institute (MCRI) and the Australasian KIDS DOSE consortium, have discovered the barriers children are experiencing in Australia, New Zealand and the Pacific Islands when accessing treatment for the antimicrobial resistant (AMR) infections deemed the highest priority by the World Health Organization.

The findings, published in The Lancet Regional Health - Western Pacific, found of the 12 antibiotics recommended for serious bloodstream infections caused by a harmful bacteria, Gram-negative bacteria, only six were licensed in children aged under 12 and just three in babies. Standard antibiotic doses were also often too low for children under 12 years.

AMR is a growing public health problem, causing 1.27 million deaths globally every year, including 250,000 children under five years old. In Australia, one in five childhood infections caused by Gram-negative bacteria is antibiotic resistant with rates of infection much higher among First Nations children.

Associate Professor Amanda Gwee said more research was required to address significant equity and access gaps that prevent appropriate treatment for children. 

“Our review found limited treatment options for children who have life-threatening illnesses caused by MRSA (a drug-resistant staph infection) and VRE infections (caused by bacteria in the gut), especially those in the Pacific Islands,” she said.

“The KIDS DOSE network is building evidence to ensure children, the most vulnerable to serious infections, receive safe, effective antibiotic doses while supporting low resource countries to better detect and monitor AMR in their communities,” she said.

Associate Professor Gwee said while it had been challenging to get a full picture of antimicrobial resistance, the findings helped identify ongoing research priorities.

“The increase in AMR is making common infections untreatable, increasing severe illness, disability and death, and undermining modern medicine that relies on effective antimicrobials,” she said.

“To confront the challenge, we need coordinated action that improves AMR surveillance systems, supports more clinical trials involving children, removes licensing restrictions and upgrades laboratory infrastructure and technical expertise.”

Associate Professor Gwee said the KIDS DOSE Consortium would address the issue by trialling how newer antibiotics perform against bloodstream, bone and urinary tract infections in children, accelerating more effective treatments.
