Vela, its X-ray nebula, and the polarization of pulsar radiation

, 2001
The recent identification of the perpendicular mode of radio polarization as the primary one in the Vela pulsar by Lai et al. (2001) is interpreted in terms of the maser mechanism proposed by Luo & Melrose (1995).

Post-midnight purple arc and patches appeared on the high latitude part of the auroral oval: Dawnside counterpart of STEVE?

Earth, Planets and Space
The phenomenon known as strong thermal emission velocity enhancement (STEVE) is a purple/mauve arc-shaped atmospheric glow observed at lower latitudes of the auroral oval on the duskside.

Infrared measurements of spacecraft glow planned for Spacelab 2 [PDF]

A liquid helium cooled infrared telescope (IRT) was to be flown in July 1985 on Spacelab 2. The instrument is designed to measure both diffuse and discrete infrared astronomical sources, including the zodiacal light, galactic, and extragalactic ...

Spatiotemporal dynamics of β‐arrestin‐mediated Src activation in 5‐HT7 receptor signaling pathway

The FEBS Journal, EarlyView.
GPCRs induce distinct cellular responses via G protein‐ or β‐arrestin‐mediated signaling pathways. This study revealed that β‐arrestin‐biased 5‐HT7R ligand induces slow, sustained Src activation, contrasting with transient G protein‐mediated activation.

A molecular cloud within the light echo of V838 Monocerotis

, 2011
Context. V838 Mon is an eruptive variable, which exploded in 2002. It displayed the most spectacular light echo ever observed. However, neither the origin of the reflecting matter nor the nature of the 2002 outburst have been firmly constrained. Aims. We

Hypoxic and Fe‐Responses are Regulated by the ERFVII Factors and the PCO Branch of the N‐Degron Pathway According to Iron Availability

Plant, Cell &Environment, EarlyView.
ABSTRACT In plants, iron homeostasis and oxygen metabolism are strictly related, indeed several Fe‐requiring enzymes catalyze reactions that also involve O2 as a reagent, product, entry or end point of the pathway. Oxygen sensing itself relies on the Fe‐dependent enzymes Plant cysteine oxidases.

An Optics Field Site for Auroral Studies [PDF]

, 1958
The earlier orbits and ephemerides for the Soviet satellites were not sufficiently accurate to be very useful in making observations in Alaska. Extrapolations from our own observations gave better predictions.

The Impact of an Integrated steM Camp on Middle School Students' Enjoyment, Career Knowledge, and Career Interest

School Science and Mathematics, EarlyView.
ABSTRACT Much of the work in STEM camps tends to be science‐driven with little attention given to mathematics. Guided by a mixed methods embedded research design using data from observations, questionnaires, and a group interview, we investigate if a camp that explicitly integrates mathematics had a positive impact on middle school students' STEM ...
