Medicaid expansion and overall mortality among women with breast cancer

JAMA Network Open

2026-01-27

(Press-News.org) About The Study: The findings of this cohort study suggest that Medicaid expansion under the Affordable Care Act was associated with lower overall mortality among women ages 40 to 64 with breast cancer. Benefits were uneven, underscoring persistent racial and ethnic and socioeconomic disparities and the need for targeted interventions.

Acupuncture for migraine without aura and connection-based efficacy prediction

2026-01-27

About The Study: This trial demonstrated acupuncture’s efficacy for migraine without aura pain relief and functional improvement. Connectome-based predictive modeling identified default mode network and subcortical cerebellum hypoconnectivity as predicting pain relief and subcortical-cerebellum-motor hyperconnectivity as predicting reduced disability, providing a personalized treatment framework.

Liverpool scientists discover graphene’s electronic properties in 3D material in boost for green computing

2026-01-27

University of Liverpool researchers have discovered a way to host some of the most significant properties of graphene in a three‑dimensional (3D) material, potentially removing the hurdles for these properties to be used at scale in green computing. Graphene is famous for being incredibly strong, lightweight, and an excellent conductor of electricity and its applications range from electronics to aerospace and medical technologies. However, its two-dimensional (2D) structure makes it mechanically fragile and limits its use in demanding environments and large-scale applications. In a paper published today, a team of researchers have identified that 3D material, HfSn₂, ...

Xigou site discovery challenges long-held views on early human technology in East Asia

2026-01-27

An international research team has uncovered evidence of advanced stone tool technologies in East Asia dating back 160,000 to 72,000 years, with the findings recently published in Nature Communications. Led by the Institute of Vertebrate Paleontology and Paleoanthropology (IVPP) of the Chinese Academy of Sciences, the team—which included researchers from China, Australia, Spain, and the United States—conducted multidisciplinary archaeological investigations at the Xigou site in the Danjiangkou Reservoir ...

Tiny gold spheres could improve solar energy harvesting

2026-01-27

Sunbeams contain a lot of energy. But current technology for harvesting solar power doesn’t capture as much as it could. Now, in ACS Applied Materials & Interfaces, researchers report that gold nanospheres, named supraballs, can absorb nearly all wavelengths in sunlight — including some that traditional photovoltaic materials miss. Applying a layer of supraballs onto a commercially available electricity converter demonstrated that the technology nearly doubled solar energy absorption compared to traditional materials. Scientists are exploring materials that absorb light ...

A rich social environment is associated with better cognitive health outcomes for older adults, study finds

2026-01-27

Research by an interdisciplinary team from McGill University and Université Laval provides new insights into the links between social factors and cognitive health among aging adults. While previous research had found positive correlations between specific measures of social connectedness and a variety of health outcomes, this study appears to have been the first to create profiles aggregating multiple social factors and to see how those correlated with cognitive health in older adults, the researchers said. The team derived three social environment ...

Electroencephalography enables continuous decoding of hand motion angles in polar coordinates

2026-01-27

With the development of brain-computer interface (BCI) technology, the application of electroencephalography (EEG) signals in motion decoding has been expanding. Traditional BCI decoding is primarily based on Cartesian coordinates, which are suitable for representing linear movements but less efficient for decoding rotational or circular movements. In contrast, polar coordinates provide a more natural and compact representation for circular movements by directly encoding angular information, making it more efficient for decoding rotational ...

This flower evolved a new shape so that different birds could pollinate it. Then, it spread.

2026-01-27

Lipstick vines get their name from their bright red, tube-shaped flowers. But one member of this group of plants has lost its lipstick-like appearance— its flowers are shorter, wider, and yellowish green in color. It also attracts shorter-beaked birds than its crimson cousins do, and it’s found in different places. Scientists wanted to know how this plant evolved from its lipstick-like relatives. After observing birds visiting hundreds of plants and examining the plants’ DNA, the researchers found that the story of the green ...

Scientists engineer unsinkable metal tubes

2026-01-27

More than a century after the Titanic sank, engineers still have hopes of someday creating “unsinkable” ships. In a step toward reaching that lofty goal, researchers at the University of Rochester’s Institute of Optics have developed a new process that turns ordinary metal tubes unsinkable—meaning they will stay afloat no matter how long they are forced into water or how heavily they are damaged. Chunlei Guo, a professor of optics and of physics and a senior scientist at URochester’s Laboratory ...

Used EVs currently offer car buyers lowest lifetime cost of ownership

2026-01-27

Now is a great time for anyone who's shopping for a used car to consider an electric vehicle, according to new research from the University of Michigan. In assessing the lifetime ownership costs of used vehicles with different body styles and powertrains, the researchers found that completely electrified candidates offered the greatest savings. For example, compared with a new midsized SUV with an internal combustion engine, a 3-year-old used EV version offered a lifetime savings of $13,000, according to the new study published in ...
