Questions Should Have Answers

European Journal of Philosophy, Volume 34, Issue 2, Page 423-440, June 2026.
ABSTRACT Making sense of the world often requires one to come up with new ideas, including ideas one had previously been unable to think of. How and when should this be done? I propose and defend a norm of rationality linking wondering, belief, and abilities to conceive: one must not both wonder a question and reject all answers to it that one can ...

Four-hundred Very Metal-poor Stars Studied with LAMOST and Subaru. III. Dynamically Tagged Groups and Chemodynamical Properties

The Astrophysical Journal
Very metal-poor (VMP) stars record the signatures of early accreted galaxies, making them essential tools for unraveling the early stages of Galaxy formation.

Black holes in the Milky Way Galaxy

Proceedings of the National Academy of Sciences, 1999
Extremely strong observational evidence has recently been found for the presence of black holes orbiting a few relatively normal stars in our Milky Way Galaxy and also at the centers of some galaxies. The former generally have masses of 4–16 times the mass of the sun, whereas the latter are “supermassive black holes” with millions to billions of ...

Evaluating Trans‐Fatty Acids Labelling in Packaged Foods Sold in Brazil Before and After National Policy Changes

Journal of Human Nutrition and Dietetics, Volume 39, Issue 3, June 2026.
ABSTRACT Introduction The elimination of industrial trans‐fatty acids (i‐TFA) is a global public health priority. In Brazil, food regulatory changes were implemented in 2012, limiting the use of TFA‐free claims and in 2019, restricting i‐TFA content in food. This study analysed i‐TFA declarations on labels of packaged foods sold in Brazil in 2010, 2013

Molecular hydrogen in galaxies [PDF]

, 1987
This study aims to understand the key role played by molecular hydrogen in the evolution of galaxies, with a view to constraining its radial distribution in the Galaxy and the CO→H(_2) conversion factor α(_20).The star formation rate is shown to be ...

Generalized Rotation Curves of the Milky Way from the GAIA DR3 Data Set: Constraints on Mass Models

The Astrophysical Journal
The circular velocity curve traced by stars provides a direct means of investigating the potential and mass distribution of the Milky Way. Recent measurements of the Galaxy’s rotation curve have revealed a significant decrease in velocity for Galactic ...

Archives of impact: The politics of craters on Earth

Geographical Research, Volume 64, Issue 2, May 2026.
This paper examines Earth’s 195 confirmed impact craters as archives, exploring their cataloguing and presentation as heritage sites. It argues Western scientific framings using military language and emphasising catastrophe overlook settler colonialism’s violent histories and marginalise indigenous earth‐sky cosmologies.

Environmental Enrofloxacin Exposure as a Modifiable Driver of Mitochondria‐Mediated Intestinal Aging and Barrier Dysfunction

Aging Cell, Volume 25, Issue 5, May 2026.
Environmentally relevant enrofloxacin accelerates intestinal aging by impairing epithelial mitochondrial function, disrupting barrier integrity, and reshaping the gut microbiota. Mitochondrial restoration with pyrroloquinoline quinone alleviates hypoxia, inflammation, and gut damage.

Watching Our Galaxy Grow Up: The Mass and Color Evolution of the Milky Way

The Astrophysical Journal
Using our rich observations within the Milky Way to better understand galaxy evolution requires understanding what the Milky Way looks like “as a galaxy”—that is, its “true” shape and abundance profiles (unskewed by observational biases), signatures of ...

Whole Blackcurrant (Ribes nigrum) Alleviates High‐Fat Diet Induced‐Obesity and Colonic Inflammation by Modulating the Gut Microbiota in Mice

Molecular Nutrition &Food Research, Volume 70, Issue 7, 15 April 2026.
Obesity caused by a high‐fat diet (HFD) is known to result from interactions between the gut microbiota, intestinal barrier function, and excessive inflammatory responses in the colon. In this study, we found that dietary intake of whole blackcurrants prevented HFD‐induced obesity by restoring gut microbiota dysbiosis, upregulating intestinal barrier ...
