TOI-2015 b: A Warm Neptune with Transit Timing Variations Orbiting an Active Mid-type M Dwarf

The Astronomical Journal
We report the discovery of a close-in ( P _orb = 3.349 days) warm Neptune with clear transit timing variations (TTVs) orbiting the nearby ( d = 47.3 pc) active M4 star, TOI-2015.

ALKBH3 m1A Demethylase Deficiency Reduces Alzheimer's Amyloid‐β Pathology

Advanced Science, Volume 13, Issue 32, 9 June 2026.
This study identifies that ALKBH3‐driven m1A demethylation orchestrates Alzheimer's disease progression by disrupting mitochondrial and synaptic homeostasis. This epitranscriptomic mechanism suppresses PINK1‐mediated mitophagy via m1A erasure, leading to mitochondrial dysfunction, oxidative stress, elevated Aβ production, and impaired microglial ...

HST/FGS Photometry of Planetary Transits of HD 209458 [PDF]

AIP Conference Proceedings, 2004
We present the data, and modeling and analysis results from the photometric monitoring of five planetary transits of HD 209458 using the Fine Guidance Sensors (FGS) onboard the Hubble Space Telescope (HST). We have now included the output from all four FGS photometers in our data reduction and analysis increasing our S/N over our previous results.

Neuromodulator Dynamics Underlying Associative Learning in the Ventral Striatum's Olfactory Tubercle

Advanced Science, Volume 13, Issue 32, 9 June 2026.
Using fiber photometry and genetically encoded sensors, the dynamic release patterns of four neuromodulators in the olfactory tubercle (OT)—a brain region overlapping with the olfactory cortex and ventral striatum—were systematically monitored in response to external rewards and distinct reward‐associated learning processes.

Sono‐Mechanogenetics: Linking Ultrasound Physics With Cellular Mechanobiology

Advanced Science, Volume 13, Issue 33, 15 June 2026.
Sono‐mechanogenetics links ultrasound physics with cellular mechanotransduction to enable noninvasive control of engineered biological systems. Acoustic forces generate distinct deformation modes that activate intracellular signaling pathways, which can be coupled to synthetic gene circuits to regulate diverse cellular functions, including gene ...

OrCAS: Origins, Compositions, and Atmospheres of Sub-Neptunes. I. Survey Definition

The Astronomical Journal
Sub-Neptunes—volatile-rich exoplanets smaller than Neptune—are intrinsically the most common type of planet known. However, the formation and nature of these objects, as well as the distinctions between subclasses (if any), remain unclear.

Stoichiometry and Homeostasis of Sodium and Potassium Underpins Growth Adaptation of Suaeda salsa in the Yellow River Delta Wetland

Ecology and Evolution, Volume 16, Issue 6, June 2026.
Na‐K stoichiometry significantly affected by soil and plant tissues of S. salsa; robust plant tissue Na‐K homeostasis contrasts with weak soil–plant ion coupling; coordinated Na‐K regulation underlies salt adaptation in Suaeda salsa. ABSTRACT Sodium (Na) and potassium (K), along with their physiological trade‐offs, play essential roles in maintaining ...

Non-detection of Contamination by Stellar Activity in the Spitzer Transit Light Curves of TRAPPIST-1 [PDF]

, 2018
peer reviewedWe apply the transit light curve self-contamination technique of Morris et al. to search for the effect of stellar activity on the transits of the ultracool dwarf TRAPPIST-1 with 2018 Spitzer photometry.
