Trends in US preterm birth rates by household income and race and ethnicity

JAMA Network Open

2026-01-02
(Press-News.org)

About The Study: In this population-based cross-sectional study, household income disparities in preterm birth widened over time. Black race moderated the association between income and preterm birth, underscoring the need to examine the role of racism in preterm birth disparities.

Study identifies potential biomarker linked to progression and brain inflammation in multiple sclerosis

2026-01-02
A new University of Toronto-led study has discovered a possible biomarker linked to multiple sclerosis (MS) disease progression that could help identify patients most likely to benefit from new drugs. The findings were published today in Nature Immunology and validated in both mouse models and humans.  “We think we have uncovered a potential biomarker that signals a patient is experiencing so-called ‘compartmentalized inflammation’ in the central nervous system, a phenomenon which is strongly liked ...

Many mothers in Norway do not show up for postnatal check-ups

2026-01-02
In a new study, Christine Agdestein has surveyed several aspects of the postnatal check-up. Agdestein is a specialist in general practice and a general practitioner, and is currently a PhD candidate at the Norwegian University of Science and Technology (NTNU). The research project is part of her PhD. "An important finding is that the majority are satisfied with the 6-week check-up with their GP. This is an important offer for those who have recently given birth. GPs have an important role in postnatal care," says Christine Agdestein. "Not much research has been done on the postnatal check-up before, and therefore it is extra rewarding that we can ...

Researchers want to find out why quick clay is so unstable

2026-01-02
Quick clay is actually an old seabed. The clay thus formed under water, but came to the surface when the landscape rose after the last ice age. However, this clay was not so dangerous, because it was full of salt from the sea. Only when the salt in the clay was washed out of fresh water from rain and groundwater did it turn into quick clay. But what exactly makes quick clay so unstable? "We have made very detailed and careful simulations of the friction between clay particles," says researcher and doctor Ge Li at PoreLab and the Department of Mechanical Engineering and Production at the Norwegian University of Science ...

Superradiant spins show teamwork at the quantum scale

2026-01-02
When quantum particles work together, they can produce signals far stronger than any one particle could generate alone. This collective phenomenon, called superradiance, is a powerful example of cooperation at the quantum level. Until now, superradiance was mostly known for making quantum systems lose their energy too quickly, posing challenges for quantum technologies. But a new study published in Nature Physics turns this idea on its head— revealing that collective superradiant effects ...

Cleveland Clinic Research links tumor bacteria to immunotherapy resistance in head and neck cancer

2026-01-02
Cleveland: Cleveland Clinic researchers have discovered that bacteria inside cancerous tumors may be key to understanding why immunotherapy works for some patients but not others. Two new studies, published simultaneously in Nature Cancer, reveal that elevated levels of bacteria in the tumor microenvironment suppress immune response, driving resistance to immunotherapy in patients with head and neck squamous cell carcinoma. “These studies shift the focus of immunotherapy resistance research beyond tumor genetics ...

First Editorial of 2026: Resisting AI slop

2026-01-01
The first Editorial of the year at Science always gives the Editor-in-Chief an opportunity to reflect on notable developments for the Science journals. In this Editorial, Holden Thorp focuses on AI, discussing how it “will allow the scientific community to do more if it picks the right ways to use it.” He revisits the journals’ policies and approaches related to AI. The journals do use select AI tools. Over the past year for example, Science has collaborated with DataSeer to evaluate adherence to its policy mandating the sharing of underlying data and code for all published ...

Joint ground- and space-based observations reveal Saturn-mass rogue planet

2026-01-01
Simultaneous ground- and space-based observations of a newly discovered free-floating planet have enabled direct measurement of its mass and distance from Earth, according to a new study. The findings offer insights into the diverse and dynamic pathways by which planets can be cast adrift into interstellar space. Although studies to date have only revealed a handful of such free-floating planets, detections are expected to increase in the coming years, particularly with the NASA Nancy Grace Roman Space Telescope campaign that is scheduled for launch in 2027, ...

Inheritable genetic variant offers protection against blood cancer risk and progression

2026-01-01
A newly identified and rare genetic variant slows the growth of mutated blood stem cells, researchers report, and it reduces the risk of leukemia. The findings offer insight into why some people are naturally more resistant to clonal expansion and age-related blood cancers despite acquiring risky mutations. As tissues age, they quietly accumulate many mutations that can drive cancer. In the blood-forming, or hematopoietic, system, such mutations often appear in otherwise healthy individuals as clonal hematopoiesis (CH), a process in which certain blood stem cell (HSC) ...

Pigs settled Pacific islands alongside early human voyagers

2026-01-01
Pigs across the Pacific can trace their ancestry to Southeast Asian domestic pigs that accompanied early Austronesian-speaking groups as they island-hopped across the region, according to a new genomic study. For thousands of years, humans have moved animals far beyond their natural ranges – sometimes accidentally and sometimes deliberately, but often with profound ecological consequences, especially on islands. Pigs are a striking example; although their home ranges lie mostly west of the Wallace Line, multiple species are now widespread across the islands of Southeast Asia and throughout Oceania. Archaeological and genetic evidence suggest that pigs ...

A Coral reef’s daily pulse reshapes microbes in surrounding waters

2026-01-01
A new study shows that coral reefs don’t just provide a home for ocean life, they also help set the daily “schedule” for tiny microbes living in the water nearby. Over the course of a single day, the quantity and types of microbes present can shift dramatically. To see this in detail, researchers took frequent water samples and used a mix of genetic and ecological methods and tools, as well as advanced imaging techniques, to track what was happening hour by hour. They found that reefs can shape microbial communities ...
