Phytoplankton Tune Local pH to Actively Modulate Circadian Gravitactic Behavior

Advanced Physics Research, EarlyView.
Diel vertical migration hides an unexpected twist: Phytoplankton quietly engineer their local pH landscape, splitting into behaviorally distinct sub‐groups which stay separated even in identical conditions. Circadian pH changes, occuring over the course of a day, reshape their gravitactic behavior and physiological functions in ways scientists have ...

BRITE-Constellation: Data processing and photometry [PDF]

, 2017
The BRITE mission is a pioneering space project aimed at the long-term photometric monitoring of the brightest stars in the sky by means of a constellation of nano-satellites. Its main advantage is high photometric accuracy and time coverage inaccessible

Confirmation of a Non‐Transiting Planet in the Habitable Zone of the Nearby M Dwarf L 98‐59

Astronomische Nachrichten, EarlyView.
ABSTRACT Only 40 exoplanetary systems with five or more planets are currently known. These systems are crucial for our understanding of planet formation and planet‐planet interaction. The M dwarf L 98‐59 has previously been found to show evidence of five planets, three of which are transiting.

Possible therapeutic repositioning of valproic acid: From epileptic seizures to acute kidney injury

British Journal of Clinical Pharmacology, EarlyView.
Valproic acid, an anticonvulsant, may be repositioned to prevent acute kidney injury due to ischemia followed by reperfusion. It preserves renal functions, electrolyte homeostasis and active sodium transport in kidney tubules, and blocks the onset of hypertension.

Determination of Thermal DNA‐Stability With Respect to PCR or How to Debunk a Pseudoscientific Claim

Biochemistry and Molecular Biology Education, EarlyView.
ABSTRACT Debunking pseudoscience is difficult, especially for early‐career students and the public. Recently, in particular the Corona pandemic has spawned a whole range of pseudoscientific claims and conspiracy theories, many of which are publicly available in the style of scientific articles on preprint servers, in predatory journals, or in some ...

The Influence of Drosophila Spire and Myosin V During Mid‐Oogenesis Is Independent of Their Direct Interaction

Cytoskeleton, EarlyView.
ABSTRACT Cooperativity between cytoskeletal proteins is crucial for spatiotemporal coordination in biological processes, like oogenesis. In mammalian and Drosophila oogenesis, proper assembly and function of actin networks require coordination between actin assembly factors Spire and formins, as well as actin‐associated proteins like myosins and Rab ...

Herschel far-infrared photometry of the Swift Burst Alert Telescope active galactic nuclei sample of the local universe – III. Global star-forming properties and the lack of a connection to nuclear activity [PDF]

, 2016
We combine the Herschel Space Observatory PACS and SPIRE photometry with archival WISE photometry to construct the spectral energy distributions (SED) for over 300 local ($z 0.5$), especially at higher luminosities ($L_{14-195\,\rm{keV}} > 10^{42.5 ...
