15 most pressing issues for conservation, including invertebrate decline and changing marine ecosystems      (via sciencedaily.com)     Original source 

Since 2009, the Cambridge Conservation Initiative has coordinated an annual horizon scan, a well-established method for predicting which threats, changes, and technologies will have the biggest impact on biological conservation in the following year. This year, the 15th horizon scan included 31 scientists, practitioners, and policymakers who developed a list of 96 issues, which they eventually narrowed down to the fifteen most novel and impactful. Their findings include topics related to sustainable energy, declining invertebrate populations, and changing marine ecosystems.

Genetic atlas detailing early stages of zebrafish development      (via sciencedaily.com)     Original source 

Researchers have published an atlas of zebrafish development, detailing the gene expression programs that are activated within nearly every cell type during the first five days of development, a period in which embryos mature from a single cell into distinct cell types.

Opportunities to improve future HIV vaccine candidates      (via sciencedaily.com)     Original source 

An effective HIV vaccine may need to prompt strong responses from immune cells called CD8+ T cells to protect people from acquiring HIV, according to a new study. The study findings draw comparisons between the immune system activity of past HIV vaccine study participants and people with HIV who naturally keep the virus from replicating even in the absence of antiretroviral therapy (ART). The latter individuals are often called 'long-term non-progressors' or 'elite controllers' (LTNPs/ECs).

How the immune system fights to keep herpes at bay      (via sciencedaily.com)     Original source 

In a study of lab-engineered cells, researchers identify how the immune system neutralizes the herpesvirus. The research maps, for the first time, the maneuvers used by virus and host in the cell nucleus, a poorly understood terrain of host-pathogen interaction. The findings could inform the design of new treatments for herpes and other viruses that replicate in the same way.
