Maternal nativity, race, and ethnicity and infant mortality in the US

JAMA Network Open

2026-01-06

(Press-News.org) About The Study: This population-based cohort study found that U.S.-born individuals had significantly higher odds of infant mortality compared with non–U.S.-born individuals, particularly among full-term births and among those self-identifying as Black, Hispanic, white, or more than 1 race. Sudden unexpected infant death was a major contributor to these disparities. Investigation into the underlying factors contributing to these disparities is needed.

Migration-related trauma among asylum seekers exposed to the migrant protection protocols

2026-01-06

About The Study: In this cohort study, exposure to Migrant Protection Protocols was associated with higher rates of trauma during migration among asylum seekers. Such policies may be associated with adverse health outcomes for asylum seekers, with potential downstream implications for U.S. public health and security. The Migrant Protection Protocols were introduced in January 2019 and changed U.S. asylum procedures by requiring certain asylum seekers to remain in Mexico while awaiting immigration proceedings.

Jupiter’s moon Europa has a seafloor that may be quiet and lifeless

2026-01-06

By Chris Woolston The giant planet Jupiter has nearly 100 known moons, yet none have captured the interest and imagination of astronomers and space scientists quite like Europa, an ice-shrouded world that is thought to possess a vast ocean of liquid salt water. For decades, scientists have wondered whether that ocean could harbor the right conditions for life, placing Europa near the top of the list of solar system bodies to explore. A new study led by Paul Byrne, an associate professor of Earth, environmental, and planetary sciences, throws cold water on the idea that Europa could ...

SwRI upgrades nuclear magnetic resonance laboratory for pharmaceutical R&D

2026-01-06

SAN ANTONIO — January 6, 2026 – Southwest Research Institute has upgraded its nuclear magnetic resonance (NMR) laboratory to offer robust chemical analysis of organic compounds used in drug discovery and development. Through internally funded research, SwRI used the new laboratory to compare quantitative NMR (qNMR) to high-performance liquid chromatography (HPLC), a conventional method used to determine the purity of active pharmaceutical ingredients (APIs). SwRI’s research found that qNMR can be ...

House sparrows in northern Norway can help us save other endangered animals

2026-01-06

Researchers are trying to understand why some wild species do better than others over time, as the environment changes. Researcher Kenneth Aase's research focuses on a new mathematical approach that could shed light on this question, which in turn could move us closer to understanding the loss of biological diversity. Aase is a statistician and a PhD research fellow at the Norwegian University of Science and Technology (NTNU's) Department of Mathematical Sciences. He is associated with the GPWILD ...

Crohn's & Colitis Foundation survey reveals more than 1/3 of young adults with IBD face step therapy insurance barriers

2026-01-06

NEW YORK, NY – January 6, 2026 – The Crohn’s & Colitis Foundation today revealed compelling new research pointing to major healthcare access challenges and financial burdens disproportionately affecting young adults with Inflammatory Bowel Disease (IBD). The national survey, conducted by the Foundation, assessed healthcare and financial experiences across three groups: young adults aged 18-25, adults aged 26-64, and caregivers of pediatric patients under 18. The findings, published today in Crohn’s & Colitis 360, are based on ...

Tethered UAV autonomous knotting on environmental structures for transport

2026-01-06

“Cable-driven systems excel at heavy-load transport but are limited by fixed anchoring points in unstructured environments,” explained study corresponding author Lihua Xie from Nanyang Technological University. The core innovations include (a) a human-in-the-loop knot planner integrating enclosing plane extraction, frontier-based path search, and knotting trajectory generation; (b) three key optimization metrics (enclosing planarity, tether visibility, tether clearance) ensuring task reliability; and (c) seamless integration of UAV mobility and winch load-bearing capability. “This system enables ...

Decentralized social media platforms unlock authentic consumer feedback

2026-01-06

PULLMAN, Wash. — Businesses looking for clearer insight into how consumers truly feel about their products, campaigns or brand decisions may find more authentic reactions on decentralized social media platforms, according to new research from Washington State University. The study, which was published in the European Journal of Marketing, found that people express stronger emotions and engage in less self-censorship on decentralized platforms than on traditional, centralized sites. Centralized platforms — such as Facebook, Instagram, TikTok, YouTube and X, formerly Twitter — are owned and operated by single corporations that control content and user data. Decentralized platforms ...

This program serves as an extension of the prestigious APS John Howland Award, the highest honor bestowed by APS in recognition of distinguished leadership and contributions to academic pediatrics. The 2025 APS John Howland Award recipient, renowned pediatric pulmonology leader Bonnie W. Ramsey, MD, will visit the institution to share her knowledge and experience, exchange ideas and ...

Scientists discover first method to safely back up quantum information

2026-01-06

A team of researchers at the University of Waterloo have made a breakthrough in quantum computing that elegantly bypasses the fundamental “no cloning” problem.  Quantum computing is an exciting technological frontier, where information is stored and processed in tiny units — called qubits. Qubits can be stored, for example, in individual electrons, photons (particles of light), atoms, ions or tiny currents.  Universities, industry, and governments around the world are spending billions of dollars to perfect the technology for controlling these qubits ...

A role for orange pigments in birds and human redheads

2026-01-06

A pigment that makes feathers and hair orange helps prevent cellular damage by removing excess cysteine from cells. Pheomelanin is an orange-to-red pigment that is built with the amino acid cysteine and found in human red hair and fair skin, as well as in bird feathers. Previous research has shown that pheomelanin is associated with increased melanoma risk, raising questions about why evolution has maintained genetic variants that promote pheomelanin production. Ismael Galván and colleagues studied 65 adult zebra finches divided into treatment and control groups. In the ...
