Using the Lonsdorf model for estimating habitat loss and fragmentation effects on pollination service
Article examining the effects of habitat loss and fragmentation on pollination separately according to the Lonsdorf model. Results show that the effects of habitat loss and fragmentation on pollination are completely different at the landscape and farm levels. This article shows that using the Lonsdorf model could lead to confusing results for the landscape ecologists and farmers who want to reduce the adverse effects of fragmentation on their products by creating new forest patches.

Branching of Titanium Nanorods
This article reports that Ti nanorod branching occurs at a low homologous temperature of 0.28 based on physical vapor deposition and characterizations using electron microscopy and X-ray diffraction. The insight into conditions for branching, together with the determination of the morphology and crystal orientation of the branches, lay the foundation for further studies of branching mechanisms and driving force.

CRISPR/Cas9-Induced fad2 and rod1 Mutations Stacked With fae1 Confer High Oleic Acid Seed Oil in Pennycress (Thlaspi arvense L.)
Article utilizing Clustered Regularly Interspaced Short Palindromic Repeats (CRISPR)/Cas9 technology to produce knockout mutations in the FATTY ACID DESATURASE2 (FAD2) and REDUCED OLEATE DESATURATION1 (ROD1) genes to increase oleic acid content in Pennycress (Thlaspi arvense L.). Results suggest that combinatorial knockout of ROD1 and FAE1 may be a viable route to commercially increase oleic acid content in pennycress seed oil whereas mutations in FAD2 will likely require at least partial function to avoid fitness trade-offs.

Beyond Traits and States: Interpersonal Decentering Is Also Activated Social Information Processing
Article drawing on a process-focused model of interpersonal decentering's causal validity, the authors manipulated activation experimentally, comparing decentering scores from expressive writing essays under standard instructions (activation condition) versus control instructions, then correlated decentering scores with use of activated language. With condition controlled, both decentering scores correlated significantly with greater proportions of present-tense verbs, positive emotion words, and cognitive words, showing trait effects.

Associations between volunteering and cognitive impairment: The moderating role of race/ethnicity
Article describes how although volunteering has been shown to benefit cognitive health, there is a paucity of evidence on informal volunteering and subjective measures of cognitive impairment. The author's study aimed to examine the associations of both formal and informal volunteering with older adults' objective and subjective cognition and explore the moderating role of race/ethnicity in such associations.
