Theory of winds in late-type evolved and pre-main-sequence stars [PDF]
, 1983 Recent observational results confirm that many of the physical processes which are known to occur in the Sun also occur among late-type stars in general. One such process is the continuous loss of mass from a star in the form of a wind.

Maser, infrared and optical emission for late-type stars in the Galactic plane [PDF]
, 2017 Radio astrometric campaigns using VLBI have provided distances and proper motions for masers associated with young massive stars (BeSSeL survey). The ongoing BAaDE project plans to obtain astrometric information of SiO maser stars located in the inner ...

Organoids in pediatric cancer research
FEBS Letters, EarlyView.Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Adaptive Optics Near-Infrared Spectroscopy of the Sgr A* Cluster
, 2002 We present K-band $\lambda/\Delta\lambda$ ~ 2600 spectroscopy of five stars (K ~ 14 - 16 mag) within 0.''5 of Sgr A*, the radio source associated with the compact massive object suspected to be a 2.6 x 10$^{6}$ \msun black hole at the center of our ...

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 Astronomical JournalIn the I -band color–magnitude diagrams of resolved nearby galaxies, the reddest asymptotic giant branch ( AGB ) stars form a previously unremarked-upon, but nevertheless distinct and easily identified population of high-luminosity stars.

Asymptotic dynamos in late-type stars [PDF]
Monthly Notices of the Royal Astronomical Society, 2002 The behaviour of a simple thin-shell α‐ dynamo model is considered in the asymptotic regime, characterized by dynamo numbers much larger than the critical ones, in order to derive scaling relationships connecting the properties of dynamo waves with global stellar parameters.

The status of Galactic field lambda Bootis stars in the post-Hipparcos era
, 2002 The lambda Bootis stars are Population I, late B to early F-type stars, with moderate to extreme (up to a factor 100) surface underabundances of most Fe-peak elements and solar abundances of lighter elements (C, N, O, and S).

FEBS Letters, EarlyView.Fluorescent probes allow dynamic visualization of phosphoinositides in living cells (left), whereas mass spectrometry provides high‐sensitivity, isomer‐resolved quantitation (right). Their synergistic use captures complementary aspects of lipid signaling. This review illustrates how these approaches reveal the spatiotemporal regulation and quantitative
