Gestational diabetes significantly increases the risk of complications during pregnancy.

Early detection and intervention can help reduce pregnancy complications.
Washington, D.C.—A new study has identified early-pregnancy gut microbiota signatures associated with the development of gestational diabetes mellitus, a metabolic disorder that carries substantial risks to both maternal and fetal health. The study, published in the American Society for Microbiology journal Microbiology Spectrum, provides new avenues for gestational diabetes prevention and management.
Gestational diabetes is a prevalent metabolic disorder characterized by abnormal glucose metabolism, primarily in the mid to late stages of pregnancy. Early intervention for gestational diabetes can substantially reduce complications for both mother and baby. Gestational diabetes significantly increases the risk of maternal complications such as gestational hypertension, polyhydramnios, and cesarean delivery, while also posing long-term health risks for the fetus, including asphyxia at birth and increased susceptibility to obesity and diabetes in adulthood.
In the new study, researchers from The Second Hospital, Southern Medical University, and the Third Affiliated Hospital of Guangzhou Medical University, all in Guangzhou, China, set out to identify gut microbiota dysbiosis that is strongly linked to the onset and progression of gestational diabetes that may serve as a critical early-warning biomarker. The scientists analyzed the fecal microbiota of 61 pregnant women during their first trimester of pregnancy using 16S rRNA sequencing. They then correlated these microbial profiles with oral glucose tolerance test results at 24-28 weeks of gestation and clinical delivery outcomes.
The researchers discovered that there were significant differences in gut microbiota composition between those with gestational diabetes and women who had healthy pregnancies. Based on their findings, the researchers developed an early diagnostic model for gestational diabetes, based on genus-level markers, with high diagnostic precision.
“These findings suggest that microbiota-based tools could enable early, non-invasive detection of gestational diabetes mellitus, offering new opportunities for prevention and personalized management,” write the study authors. “This research highlights the role of the gut microbiome in pregnancy and has important implications for improving maternal and fetal health outcomes.”

NEW YORK, NY – July 1, 2025 – Research has always been critical to improving patient lives. That is why the American Thoracic Society (ATS), a Coalition to Transform Clinical Trial Engagement Steering Committee (CTCTE) member, is proud to be one of seven organizations partnering with the Foundation for Sarcoidosis Research (FSR) to make it easier for patients, including those with chronic lung disease, to join research. The Champions for Change – Paid Time Off (PTO) Initiative is a national ...
Fentanyl has killed hundreds of thousands of people globally since 2015. Detection of the drugs during interdiction is currently done through Raman spectroscopy or chemical strips—both of which require direct access to samples. Michael Malone and colleagues use a magnetic resonance technique to detect fentanyl hydrochloride inside sealed opaque containers and packages—an approach that could be used in airports, border crossings, post offices, and other contexts. Nuclear quadrupole resonance (NQR) spectroscopy sends a radio frequency pulse with ...
The Hebrew University of Jerusalem is proud to announce that Prof. Eran Meshorer has been elected as a member of EMBO, a prestigious European organization recognizing exceptional research leaders in life sciences across Europe and beyond.
“At a time when Israel faces significant challenges, it is especially meaningful to celebrate achievements that highlight the strength and resilience of our academic community. The election of Prof. Eran Meshorer to EMBO is not only a personal honor, but also a testament to the world-class research conducted at the Hebrew University. His groundbreaking work in epigenetics ...
COLUMBUS, Ohio – As glaciers retreat due to a rise in global temperatures, one study shows detailed 3D elevation models could drastically improve predictions about how they react to Earth’s warming climate.
While only 10% of Earth is covered in glacial ice, these masses have far-reaching impacts on all the world’s ecosystems. Rapid melting can trigger natural disasters, and glaciers help to regulate the planet’s temperature and sea level and are sources of pristine fresh drinking water.
To better differentiate between seasonal ice loss and that caused by long-term climate trends, ...
In a Perspective, Julio M. Ottino describes different classes of creativity and proposes a benchmark for the highest level of creativity. Combinative creativity is the process of combining existing elements to create new solutions, while transformative creativity leads to entirely new frameworks. But beyond the breakthroughs of transformative creativity, according to Ottino, is the “break-with,” a conceptual advance that destroys previous worldviews completely and ushers in a new order. Advances that rise to the level of a break-with include quantum mechanics in physics and cubism in ...
Antarctic sea ice is more than just a platform for penguins. The sea ice’s high reflectivity influences the whole Earth’s climate, and the ice is a key habitat for underwater as well as above-water ecosystems. Antarctic sea ice cover is becoming much more variable as the climate changes; there has been a string of record high years followed by years with record low areas of ice. Edward Doddridge and colleagues studied these record-low years, which they expect will become more common as the climate warms. Using observations ...
As technology increasingly integrates complex soundscapes into virtual spaces, understanding how humans perceive directional audio becomes vital. This need is bolstered by the rise of immersive media, such as augmented reality (AR) and virtual reality (VR), where users are virtually transported into other worlds. In a recent study, researchers explored how listeners identify the direction from which a speaker is facing while speaking.
The research was led by Dr. Shinya Tsuji, a postdoctoral fellow, Ms. Haruna Kashima, ...
The scientific team of Dr. Miloslav Polášek at IOCB Prague has developed a new method of separating the rare earth elements, or lanthanides, which are widely used in the electronic, medical, automotive, and defense industries. The unique method allows metals such as neodymium or dysprosium to be purified from used neodymium magnets. The environmentally friendly process precipitates the rare earths from water without organic solvents or toxic substances. The results were published in the Journal of the American Chemical Society (JACS) at the end of June.
Global demand for rare ...
CLEVELAND—Epilepsy is among the most common neurological conditions, marked by unpredictable seizures, accidents and injuries, reduced quality of life, stigma and—in the worst case—premature death.
But a program—developed over several years by a Case Western Reserve University-led research team—that teaches people with epilepsy how to “self-manage” their disorder is showing positive results.
The program has been found to help people with epilepsy reduce related health complications and improve their mood and quality of life, according to a new study recently ...
