PHR‐Mediated Pi Starvation Response Mobile Messenger RNAs Represent Noncoding Transcripts in Recipient Tissues

open access: yesAdvanced Science, EarlyView.
Mobile messenger RNAs (mRNAs) can travel long distances, serving as systemic signals that participate in plant growth and stress acclimation. This work determines that PHR proteins mediate the Pi starvation response (PSR)‐specific long‐distance transport of mRNAs and that these PSR‐specific mobile mRNAs represent noncoding transcripts in recipient ...

Preliminary Assessment of the Mars Science Laboratory Entry, Descent, and Landing Simulation [PDF]

open access: yes, 2013
On August 5, 2012, the Mars Science Laboratory rover, Curiosity, successfully landed inside Gale Crater. This landing was only the seventh successful landing and fourth rover to be delivered to Mars.

Ratoon Season Rice Reduces Methane Emissions by Limiting Acetic Acid Transport to the Rhizosphere and Inhibiting Methanogens

open access: yesAdvanced Science, EarlyView.
This study finds that the interaction between ABA‐OsCIPK2‐OsSWEET1A reduces the allocation of methane producing bacteria carbon source (acetic acid) content to the rhizosphere soil of ratoon season rice, thereby reducing methane emissions. Abstract Rice paddies are a major, persistent source of atmospheric methane (CH4), emission rates depend on the ...

Targeted Inhibition of CD74+ Macrophages by Luteolin via CEBPB/P65 Signaling Ameliorates Osteoarthritis Progression

open access: yesAdvanced Science, EarlyView.
This study identifies CD74⁺ macrophages as key drivers of synovial inflammation in osteoarthritis (OA). The flavonoid luteolin is predicted to inhibit this pathway by blocking Nuclear Factor Kappa‐light‐chain‐enhancer of Activated B cells (NF‐κB) signaling. To enhance delivery, a targeted nanoplatform (MDSPL) is developed.

A Simple and Accurate Apollo-Trained Neural Network Controller for Mars Atmospheric Entry

open access: yesInternational Journal of Aerospace Engineering, 2020
We present a new method to design the controller for Mars capsule atmospheric entry using deep neural networks and flight-proven Apollo entry data. The controller is trained to modulate the bank angle with data from the Apollo entry simulations.

Global Evidence of the Unimodal Response of Ecosystem Respiration to Soil Moisture

open access: yesAdvanced Science, EarlyView.
Using global eddy covariance observations and a field experiment, this paper provides compelling evidence for the widespread unimodal relationship between soil moisture and ecosystem respiration and its water adaptation. Such knowledge facilitates understanding of soil moisture in affecting respiratory carbon emissions and has the potential to improve ...
