(Press-News.org) Children born to mothers with cardiometabolic health issues before or during pregnancy may face a higher risk of elevated blood pressure in childhood and adolescence, according to a new study funded by the Environmental influences on Child Health Outcomes (ECHO) Program at the National Institutes of Health (NIH).
High blood pressure in childhood often continues into adulthood and is linked to a greater risk of heart problems later in life. This ECHO research offers insights into how a mother’s heart and metabolic health before and during pregnancy may contribute to her child’s long-term cardiovascular well-being.
The study analyzed data from 12,480 mother-child pairs in the ECHO Program. Researchers looked at how three maternal cardiometabolic risk factors—pre-pregnancy obesity, gestational diabetes, and high blood pressure during pregnancy—were related to children’s blood pressure from ages 2 to 18.
Key Findings:
44% of mothers in the study had at least one cardiometabolic risk factor during pregnancy.
Children whose mothers had more than one condition, such as gestational diabetes combined with high blood pressure or pre-pregnancy obesity, had higher blood pressure than those whose mothers had only one condition.
Children born to these mothers had higher average blood pressure readings, even after accounting for age, sex, and height of the child.
These children also experienced an increased rate of change in blood pressure over time, suggesting a long-term impact.
The effect was especially strong for diastolic blood pressure in girls and systolic blood pressure in non-Hispanic Black children whose mothers had gestational diabetes or high blood pressure.
“With declines in cardiometabolic health, it’s important to focus on prevention starting as early as possible,” said ECHO researcher Zhongzheng Niu, PhD, of the Keck School of Medicine at the University of Southern California. “Our study suggests that helping people improve their health before and during pregnancy could benefit both mothers and future generations."
The researchers in this study call for further studies to understand how combinations of maternal health issues and broader social and structural factors contribute to these long-term risks.

Mercury levels in the atmosphere have decreased throughout the 21st century
2025-05-08
Mercury is released by environmental and human-driven processes. And some forms, specifically methylmercury, are toxic to humans. Therefore, policies and regulations to limit mercury emissions have been implemented across the globe. And, according to research published in ACS ES&T Air, those efforts may be working. Researchers found that atmospheric mercury levels have decreased by almost 70% in the last 20 years, mainly because human-caused emissions have been reduced.
“By tracking mercury pollution over four decades at the top of the world, we show that global efforts to reduce pollution ...
This soft robot “thinks” with its legs
2025-05-08
A research team from AMOLF in Amsterdam created a soft robot that walks, hops, and swims — all without a brain, electronics, or AI. Just soft tubes, air, and some clever physics.
The study published this week in Science describes one of the fastest soft robots yet, and one of the simplest. It has no computer, no software, and no sensors. And still, it moves with surprising coordination and autonomy, simply because of its body and how it interacts with the world.
So, what’s really driving it? Underneath the movement is a principle you’ve probably seen, though maybe overlooked. Think of those wobbly, ...
Biologists identify targets for new pancreatic cancer treatments
2025-05-08
CAMBRIDGE, MA -- Researchers from MIT and Dana-Farber Cancer Institute have discovered that a class of peptides expressed in pancreatic cancer cells could be a promising target for T-cell therapies and other approaches that attack pancreatic tumors.
Known as cryptic peptides, these molecules are produced from sequences in the genome that were not thought to encode proteins. Such peptides can also be found in some healthy cells, but in this study, the researchers identified about 500 that appear to be found only in pancreatic ...
Simple tweaks to a gene underlie the stench of rotten-smelling flowers
2025-05-08
Some plants lure pollinators not with sweet fragrances, but with the rank stench of decay. In a new study, researchers show how plants pull this off. In Asarum flowers, a gene typically used for detoxifying smelly compounds has instead evolved to produce unpleasant odors, the researchers report. The findings shed light on how plants co-opt widely conserved metabolic pathways for ecological advantage. A key feature of foul-smelling flowers is the release of malodorous volatile compounds, particularly oligosulfides like dimethyl disulfide (DMDS) and dimethyl trisulfide (DMTS). These compounds mimic the chemical signals given off by decaying material. ...
Simple, effective interventions reduce emissions from Bangladesh’s informal brick kilns
2025-05-08
Simple and inexpensive interventions aimed at making changes in how Bangladesh’s informal brink kilns operate could dramatically cut emissions and boost profits for producers, according to a new study. The findings may offer a scalable model for tackling pollution in hard-to-regulate informal industries, particularly in low- and middle-income countries (LMICs). In many LMICs, weak regulatory systems limit the effectiveness of pollution control, especially in informal industries that tend to operate outside formal governance and ...
Ultrasound-guided 3D bioprinting enables deep-tissue implant fabrication in vivo
2025-05-08
A new ultrasound-guided 3D printing technique could make it possible to fabricate medical implants in vivo and deliver tailored therapies to tissues deep inside the body – all without invasive surgery, researchers report. 3D bioprinting technologies offer significant promise to modern medicine by enabling the creation of customized implants, intricate medical devices, and engineered tissues tailored to individual patients. However, most current approaches require invasive surgical implantation. Although in vivo bioprinting – “3D printing” tissue directly within the body – offers ...
Soft limbs of flexible tubes and air enable dynamic, autonomous robotic locomotion
2025-05-08
Using only airflow and simple physical design – resulting in a structure that looks like a roadside “inflatable tube dancer” – researchers have developed soft robots that achieve coordinated, autonomous movement without relying on complex electronic controllers. In nature, animals often move with remarkable efficiency. They do this by seamlessly integrating the nervous system, body mechanics, and environmental interactions. This decentralized coordination allows animals to move efficiently without relying on constant direction from the brain. In contrast, most robots depend ...
Researchers develop practical solution to reduce emissions and improve air quality from brick manufacturing in Bangladesh
2025-05-08
Brick manufacturing is a central component of the economy in South Asia, but also a major source of greenhouse gas emissions and air pollution, as the practice releases carbon dioxide (CO₂), fine particulate matter (PM2.5), and other contaminants into the environment. This coal-powered industry poses a serious threat to human health, agriculture, and the environment in low- and middle-income countries that lack the capacity to monitor and regulate these largely informal operations.

Durham University scientists solve 500-million-year fossil mystery

-With images-
A peculiar spiny fossil, once thought to represent one of the earliest molluscs, has now been conclusively reclassified by scientists from Durham University and Yunnan University as something entirely different – a distant relative of sponge-like creatures known as chancelloriids.
This striking revelation is set to reshape our understanding of early animal evolution.
The fossil, named Shishania aculeata, hails from 500-million-year-old Cambrian deposits in Yunnan Province, southern China, ...

New report shows drastic decline in endangered primates and calls for conservation measures
An international team of primate researchers has published the 25 most endangered primate species in Asia, Africa, Madagascar and South America for the years 2023 to 2025. The publication, supported by the German Primate Center (DPZ) - Leibniz Institute for Primate Research in Göttingen, emphasizes how urgently global conservation measures need to be implemented now to save irreplaceable biodiversity.
"The situation is dramatic. If we don't act now, we will lose some of these species forever," warns Christian Roos, geneticist at the German Primate Center. “But ...
