How many bromeliads are there? History and future perspectives of species scientific discovery in the pineapple family

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
It remains unclear how many plant species are not yet recorded by science. We illustrated the process by which species of the pineapple family in tropical America have been newly described to science to date, and we estimated how many species may still await scientific discovery in this group.

Cross‐Linking Mass Spectrometry of the Antimicrobial Peptides Magainin 2 and PGLa Reveals Heterodimerization in Micellar Medium

open access: yesRapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale In this study, we applied cross‐linking mass spectrometry (XL‐MS) to characterize the oligomeric states of a PGLa/magainin 2 mixture and gain insight into the heterodimerization previously suggested in the literature. Both peptides have shown a synergistic enhancement of activity when tested in antimicrobial assays; however, the ...

An Enhanced Soft‐Containing Gripper for Pick‐And‐Place of Oyster Products at Extreme Handling Speed

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Soft robotic grippers have been developed for high‐speed handling of soft, fragile foods. For example, our previously designed soft‐containing gripper has been implemented on food production lines. However, existing soft robotic grippers remain inadequate for food pick‐and‐place tasks at extreme handling speeds (e.g., > 70 pcs/min).

Reasoning Together or Clicking Through? Analyzing Patterns of Group Science Talk On and Off Individualized Computers

open access: yesScience Education, EarlyView.
ABSTRACT In this article, I examine group science talk within the classrooms of three urban secondary science teachers who regularly use one‐to‐one computers to mediate their NGSS‐aligned science instruction. I combine methods of framing analysis (Goffman 1974; Tannen 1993) and interaction analysis (Jordan and Henderson 1995) to illustrate differences ...

Practical Methodology for Developing Visions for Carbon‐Neutral Cities and Communities

open access: yesSustainable Development, EarlyView.
ABSTRACT Cities and communities play important roles in sustainable development and climate change mitigation. This study presents a novel framework for developing carbon‐neutral visions for cities and communities. We established five “principles,” investigated options encompassing four parameters (management, goal setting, actions, and quantification),
