Disengaging the Engine: Histone Deacetylases 1 and 2‐Mediated Acetylation of Hexokinase‐2 Regulates Energy Metabolism in Microglia Following Intracerebral Hemorrhage

open access: yesAdvanced Science, Volume 13, Issue 14, 9 March 2026.
This study demonstrates that HDAC1/2 knockout in microglia alleviates neurological deficits, preserves white matter, and accelerates hematoma clearance after ICH. HDAC1/2 inhibition reduces HK2 acetylation, shifts metabolism from glycolysis to fatty acid oxidation, reduces inflammation, and enhances phagocytosis.

JWST/NIRSpec Reveals the Atmospheric Driver of Saturn's Variable Magnetospheric Rotation Rate

open access: yesJournal of Geophysical Research: Space Physics, Volume 131, Issue 3, March 2026.
Abstract Past measurements of Saturn's upper atmosphere have allowed only a broad scale view of the temperature and ion density structures within the auroral region. However, Saturn's auroral currents include a planetary period current component that is produced by neutral atmospheric flows.

The pulsar luminosity function

open access: yes, 2003
We construct and examine the pulsar luminosity function using the new list which includes data for 1328 radio pulsars. In this work, the luminosity function for 1400 MHz is constructed for the first time.

Gravitoastronomy with neutron stars [PDF]

open access: yes, 2004
Recent advances in gravitational wave detectors mean that we can start to make astrophysically important statements about the physics of neutron stars based on observed upper limits to their gravitational luminosity.

Multiomics Analyses Reveal an Essential Role of Tryptophan in Treatment of csDMARDs in Rheumatoid Arthritis

open access: yesAdvanced Science, Volume 13, Issue 9, 13 February 2026.
Rheumatoid arthritis is a disease characterized by joint inflammation. Approximately 50% of patients show insufficient response to traditional synthetic disease‐modifying antirheumatic drugs. This study aims to elucidate differential molecular profiles of the mechanisms underlying drug responses through multi‐omics strategy.

A relativistic positioning system exploiting pulsating sources for navigation across the Solar System and beyond [PDF]

open access: yes, 2011
We introduce an operational approach to the use of pulsating sources, located at spatial infinity, for defining a relativistic positioning and navigation system, based on the use of null four-vectors in a flatMinkowskian spacetime.

Urban facility management for healthy cities [PDF]

open access: yes, 2019
Worldwide, sedentary behaviours and overweight are major health concerns. Most adolescents are insufficiently physically active and have overweight. Moreover, most work is sedentary or requires only light activity.

IS GEMINGA A GLITCHING PULSAR

open access: yes, 1993
The recent discovery that Geminga is a pulsar has been followed by indications of an anomalous second derivative nu double overdot = 2.8(1.6) x 10(-25) Hz s-1 in the COS-B data, yielding a braking index n congruent-to 31 +/- 18.
