Reading this review by Diaz et al. feels a bit like reading a bad report card. Although we know we’re failing in our role as Earth’s stewards, we don’t always want to be reminded of this. But, in this case we need to read and act on the suggestions for improvement. The authors review the findings…

Gall formation by plants is a commonly-seen phenomenon that occurs in response to foreign entities (here called “gall-inducers”) such as viruses, bacteria, fungi, nematodes, etc. In this review Harris and Pitzschke set out criteria for what is and is not a gall; by definition the gall is a developmental…

Multicellularity is without doubt a fantastic fluke. We know that it arose independently in plants and animals, but how many times? And is there a common “predisposition” to multicellularity in the universal common ancestor? These are the questions addressed in this review by Niklas and Newman. Looking…

In the middle part of the 20th century, cell biology leapt forward with the development of differential centrifugation methods for purifying subcellular compartments. However, these methods require large amounts of starting material and can suffer from contamination. Kuhnert et al. present a new simple…

Knowing RNA abundance is nice, but in most cases protein abundance is more biologically interesting. Traubenik et al. used TRAP  (Translating  Ribosome  Affinity  Purification) to examine efficiency of translation and contributions of non-coding and alternatively spliced RNAs during the establishment…

The ability of seeds to pack nutrients into dense stable capsules transformed plants’ and animals’ ability to thrive on land (imagine getting through your day without eating any foods derived from seeds or animals that eat seeds). Within many seeds, nutrients are packaged in lipid droplets, with…

Review: Pervasive human-driven decline of life on Earth points to the need for transformative change Reading this review by Diaz et al. feels a bit like reading a bad report card. Although we know we’re failing in our role as Earth’s stewards, we don’t always want to be reminded of this. But,…

Beyond its well-known role in muscle contraction, the cytoskeletal component actin participates in many critical cellular processes. Globular actin polymerizes into thin, flexible filaments that assemble into dynamic higher-order structures, such as bundles and networks. In addition to providing mechanical…
