Nematode-trapping fungi

Nutritional deprivation triggers a switch from saprotrophic to predatory lifestyle in soil-dwelling nematode-trapping fungi. This transcriptomic study by Hung-Che Lin, Guillermo Vidal-Diez de Ulzurrun, Yen-Ping Hsueh and colleagues reveals increased DNA replication, translation and secretion during the development of nematode traps, and a role for DUF3129 proteins in nematode adhesion.

Forming long-term memories while asleep

Understanding how individual memories are reactivated during sleep is essential in understanding memory consolidation. Jing Liu, Tatia Lee, Xiaoqing Hu and co-workers show that during human slow-wave sleep, unobtrusively re-presenting memory reminders elicits fine-grained item-specific neural representations that support the formation of long-term memories.

Centriole duplication... explained by Turing

How do mother centrioles generate only a single daughter centriole? Zachary Wilmott, Alain Goriely and Jordan Raff show that Polo-like kinase 4 (PLK4), the master regulator of centriole biogenesis, may form a simple two-component Turing-system to allow it to break symmetry and form a single site for daughter centriole assembly.

Meningeal trypanosomiasis and autoimmunity

Juan Quintana, Neil Mabbott and co-authors show that chronic brain infection with African trypanosomes induces broad meningeal responses resulting in the development of ectopic lymphoid aggregates containing autoreactive B cells; myelin basic protein is one of the autoantigens detected by autoreactive B cells, consistent with the cortical demyelination observed in experimental infections.

Midbrain role in fear response

Fear responses to threat represent an essential survival instinct. While previous work has focused primarily on the forebrain and limbic system, Hyoseo Lee, Hannah Weinberg-Wolf, Hae-Lim Lee, Andrii Rudenko, In-Jung Kim and colleagues examine the midbrain visual circuitry, identifying specific molecular mechanisms underlying its organization and fear-related behavioral function.

Cellular response to copy-back viral genomes

Lavinia González Aparicio, Carolina López and co-workers show that non-standard viral genomes of the "copy-back" type (cbVGs) trigger translation inhibition and stress granule formation during virus infection. This is independent of the global antiviral response; instead, the translation inhibition induced by cbVGs leads to a reduction in viral protein expression.

ATG9A helps form liquid flu virus inclusions

Influenza A virus infection can trigger condensation of host recycling endosomes adjacent to the endoplasmic reticulum. Sílvia Vale-Costa, Maria João Amorim and co-authors show that this a regulated process involving ATG9A, which facilitates the detachment of recycling endosomes from microtubules near the ER, revealing a novel role for ATG9A beyond autophagy.

Perspective

How many species?

How many species are there on Earth? Projections have ranged from the millions to the trillions. John Wiens looks at how a 2011 PLOS Biology study transformed this field and what is still to be done to find a definitive answer.

Perspective

Stronger publishing standards for DNA sequences

In this Perspective article, BW Thuronyi, Erika DeBenedictis and Jeffrey Barrick argue that outdated methods narratives should be replaced with DNA sequence files when publishing life sciences research.
