Development of Nanoflare Nanosensors for Monitoring Cellular Insulin mRNA in Beta Cells and Islets
Advanced Materials Technologies, EarlyView.This study presents the design and application of In2‐NF probes for detecting insulin mRNA in beta cells and islets. Using spherical nucleic acid‐coated gold nanoparticles, the probes offer strong fluorescent signals upon hybridization. Their performance is validated across 2D and 3D cultures and rat islets, demonstrating sensitive, real‐time mRNA ...

Flares in Open Clusters with K2. I. M45 (Pleiades), M44 (Praesepe) and M67
, 2018 The presence and strength of a stellar magnetic field and activity is rooted in a star's fundamental parameters such as mass and age. Can flares serve as an accurate stellar "clock"? To explore if we can quantify an activity-age relation in the form of

Stellar flares are far-ultraviolet luminous
Monthly Notices of the Royal Astronomical SocietyABSTRACT We identify 182 flares on 158 stars within 100 pc of the Sun in both the near-ultraviolet (NUV; $1750\!-\!2750$ Å) and far-ultraviolet (FUV; $1350\!-\!1750$ Å) using high-cadence light curves from the Galaxy Evolution Explorer. Ultraviolet (UV) emission from stellar flares plays a crucial role in determining the habitability of ...

Flare Stars in Stellar Aggregates [PDF]
International Astronomical Union Colloquium, 1977 After the report on flare stars presented by Ambartsumian and the author (1971) at the last Bamberg Colloquium, some success has been achieved in the study of these interesting objects.Optical observations of stellar flares with high time-resolution undoubtedly proved the explosive character of this phenomenon and the non-thermal nature of the ...

The Anatomical Record, EarlyView.Abstract Basking sharks, Cetorhinus maximus (Gunnerus, Brugden [Squalus maximus], Det Kongelige Norske Videnskabers Selskabs Skrifter, 1765, vol. 3, pp. 33–49), feed by gaping their mouths and gill slits, greatly reorienting their cranial skeletons to filter food from water.

Analyzing the Morphology of Late-phase Stellar Flares from G-, K-, and M-type Stars
The Astrophysical JournalStellar flares occasionally present a peak-bump light-curve morphology, consisting of an initial impulsive phase followed by a gradual late phase.

The Anatomical Record, EarlyView.Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.

The Astronomical JournalWe examine 4 yr of Kepler 30 minutes data, and five sectors of Transiting Exoplanet Survey Satellite 2 minutes data for the dM3 star KIC-8507979/TIC-272272592. This rapidly rotating ( P = 1.2 day) star has previously been identified as flare active, with

The Shape of M Dwarf Flares in Kepler Light Curves
, 2015 Ultra-precise light curves from Kepler provide the best opportunity to determine rates and statistical properties of stellar flares. From 11 months of data on the active M4 dwarf, GJ 1243, we have built the largest catalog of flares for a single star ...
