The impacts of coronal mass ejections on the space environments of Venus and Mars

open access: yes地球与行星物理论评
Coronal mass ejections (CME) are solar transients, and their impacts on the planets within the solar system have attracted considerable attention. As neighboring planets within the solar system, Venus and Mars are also directly and indirectly affected by

An Overview of the 13:8 Mean Motion Resonance between Venus and Earth

open access: yes, 2009
It is known since the seminal study of Laskar (1989) that the inner planetary system is chaotic with respect to its orbits and even escapes are not impossible, although in time scales of billions of years.

The average magnetic field draping and consistent plasma properties of the Venus magnetotail [PDF]

open access: yes, 1986
A new technique has been developed to determine the average structure of the Venus magnetotail (in the range from −8 Rv to −12 Rv) from the Pioneer Venus magnetometer observations.

Timing Mechanotransduction: Mechanically Dynamic Biomaterials Reveal the Temporal Hierarchy of YAP/TAZ Control Nodes

open access: yesAdvanced Science, EarlyView.
This work develops dynamically softening polyacrylamide hydrogels for time‐resolved imaging during continuous mechanical transitions. The study revealed that mechanotransduction is biphasic; YAP/TAZ inactivation is driven by early loss of the nucleocytoskeletal continuum connecting subnuclear adhesions, F‐actin, and the nuclear envelope, coupled with ...

S100A14 in Tumor‐Derived EVs Targets PIAS3 to Reprogram Astrocytes and Induce Immunosuppressive Microenvironment Promoting Brain Metastasis and Germacrone Reversal Effect

open access: yesAdvanced Science, EarlyView.
This study identifies S100A14 in tumor‐derived exosomes as a key driver of brain metastasis. S100A14 targets PIAS3 in astrocytes, activating STAT3 signaling and promoting immunosuppressive MDSCs recruitment via chemokine secretion. Germacrone, a natural compound, binds S100A14 to disrupt this axis, effectively inhibiting brain metastasis with low ...

Post‐delisting dilemma: Long‐term success of Chrysopsis floridana introductions depends on continued fire management

open access: yesConservation Science and Practice
The Endangered Species Act aims to recover imperiled species to the point of delisting; however, few plant species have been delisted due to recovery.

Erasable FAP Targeted Spray‐On Probe for Fluorescence‐Guided Surgery

open access: yesAdvanced Science, EarlyView.
We present the first erasable spray‐on probe for fluorescence‐guided surgery. Following topical delivery, FAP‐FLASH550 targets fibroblast activation protein–expressing stromal cells, delineating tumor margins with high tumor‐to‐background ratios. A 365 nm UV light pulse rapidly erases fluorescent signals through triazene photodegradation and subsequent

Evidence for dust accumulation just outside the orbit of Venus [PDF]

open access: yes, 2007
To contribute to the knowledge of dynamics of interplanetary dust we are searching for structures in the spatial distribution of interplanetary dust near the orbit of Venus.
