The APM Proper Motion Project - I. High proper motion stars [PDF]
Monthly Notices of the Royal Astronomical Society, 1992 Results are presented on a subset of proper motion data with |μ|≥0.04 arcsec yr −1 from the APM Proper Motion Project. Comparisons made with the NLTT catalogue show that the levels of contamination and incompleteness in this catalogue are consistent with the random measuring errors in the proper motions.

Chandra Proper Motions and Milliarcsecond Astrometry of 19 Pulsars
The Astrophysical JournalWe present X-ray proper motion (PM) measurements of 19 pulsars using new and archival data from the Chandra X-ray Observatory, including pulsar wind trails and X-ray filaments. Precise X-ray PMs are often limited by uncertainties in aligning observations

Reciprocal control of viral infection and phosphoinositide dynamics
FEBS Letters, EarlyView.Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.

The Timing and Polarization of PSR J0002+6216
The Astrophysical JournalThe combined timing analysis of data from the Five-hundred-meter Aperture Spherical radio Telescope (FAST) and the Fermi Large Area Telescope confirmed that PSR J0002+6216 is not a hyper-velocity (exceeding 1000 km s ^−1 ) pulsar.

Structural insights into an engineered feruloyl esterase with improved MHET degrading properties
FEBS Letters, EarlyView.A feruloyl esterase was engineered to mimic key features of MHETase, enhancing the degradation of PET oligomers. Structural and computational analysis reveal how a point mutation stabilizes the active site and reshapes the binding cleft, expading substrate scope.

Massive Hypervelocity Runaway Stars in the Large Magellanic Cloud
The Astrophysical Journal, 2023 Since the hypervelocity stars were discovered in the Milky Way, various mechanisms have been proposed to explain these runaway stars. Up to now, however, the dominant ejected mechanism of hypervelocity stars is still unclear.

An isoform of 14‐3‐3 protein regulates transbilayer lipid movement at the plasma membrane
FEBS Letters, EarlyView.Loss of 14‐3‐3ζ in CHO cells confers resistance to exogenous phosphatidylserine (PS) and impairs endocytosis‐independent inward flip‐flop of fluorescent PS at the plasma membrane. RNAi‐mediated knockdown reproduces this defect, while no additive effect is seen in ATP11C‐deficient cells.

JWST-TST Proper Motions. I. High-precision NIRISS Calibration and Large Magellanic Cloud Kinematics
The Astrophysical Journal, 2023 We develop and disseminate effective point-spread functions and geometric-distortion solutions for high-precision astrometry and photometry with the JWST NIRISS instrument. We correct field dependencies and detector effects, and assess the
