From Natural Discovery to AI‐Guided Design: A Curated Collection of Compact Enhancers for Crop Engineering

Advanced Science, EarlyView.
ABSTRACT Precise transgene‐free gene upregulation remains a challenge in crop biotechnology, as conventional enhancers often exceed CRISPR‐mediated knock‐in size constraints and face regulatory hurdles. Here we establish a foundational cross‐species resource of compact transcriptional enhancers developed via STEM‐seq, a high‐throughput screening ...

A Shocking Solar Nebula?

, 2009
It has been suggested that shock waves in the solar nebula formed the high temperature materials observed in meteorites and comets. It is shown that the temperatures at the inner rim of the solar nebula could have been high enough over a sufficient ...

Harnessing the Neurobiology of Empathy and Compassion to Alleviate Burnout in Neurology

Annals of Neurology, EarlyView.
The neurologist cares for patients with complex chronic conditions that compromise their wellbeing. Many such disorders are poorly understood. Whereas for some, effective symptomatic treatments exist, for most we lack an understanding of the molecular and cellular bases for disease pathogenesis needed for discovering disease‐modifying treatments ...

A PeVatron Candidate: Modeling the Boomerang Nebula in X-ray Band

Universe, 2022
Pulsar wind nebula (PWN) Boomerang and the associated supernova remnant (SNR) G106.3+2.7 are among candidates for the ultra-high-energy (UHE) gamma-ray counterparts published by LHAASO.

The Herschel view of the nebula around the luminous blue variable star AG Carinae

, 2015
Far-infrared Herschel PACS imaging and spectroscopic observations of the nebula around the luminous blue variable (LBV) star AG Car have been obtained along with optical imaging in the Halpha+[NII] filter.

Origin of volatiles in the Main Belt [PDF]

, 2007
We propose a scenario for the formation of the Main Belt in which asteroids incorporated icy particles formed in the outer Solar Nebula. We calculate the composition of icy planetesimals formed beyond a heliocentric distance of 5 AU in the nebula by ...

Discovery and Initial Investigation of a New Low Surface Brightness Planetary Nebula Candidate at High Galactic Latitude

Astronomische Nachrichten, EarlyView.
ABSTRACT Planetary nebulae represent a late evolutionary phase of low‐ to intermediate‐mass stars. In this article, we present the serendipitous discovery of a previously unknown, faint potential Galactic planetary nebula (PN) in the constellation Camelopardalis, identified during a survey‐inspection, aiming at the detection of dwarf companions of the ...

Directly Tracing Cool Filamentary Accretion over >100 kpc into the Interstellar Medium of a Quasar Host at z = 1

The Astrophysical Journal Letters, 2022
We report the discovery of giant (50−100 kpc) [O ii ] emitting nebulae with MUSE in the field of TXS 0206−048, a luminous quasar at z = 1.13. “Down-the-barrel” UV spectra of the quasar show absorption at velocities coincident with those of the extended ...

On the X-ray Image of The Crab Nebula: Comparison with Chandra Observations

, 2003
An axisymmetric model for the Crab Nebula is constructed to examine the flow dynamics in the nebula. The model is based on that of Kennel and Coroniti (1984), although we assume that the kinetic-energy-dominant wind is confined in an equatorial region ...

A protosolar nebula origin for the ices agglomerated by Comet 67P/Churyumov-Gerasimenko [PDF]

, 2016
The nature of the icy material accreted by comets during their formation in the outer regions of the protosolar nebula is a major open question in planetary science.
