Journal Club: New roles found for protein key to neurotransmission

  Scientists know many of the proteins that make neurotransmission possible, but they don’t have a handle on how all the pieces work together.  “As someone who has studied the synapse for a long time, I still find it frustrating … Continue reading

Journal Club: CRISPR elucidates genetic basis of social behavior in ants

Drosophila has been a workhorse of genetics for roughly a century. But as a solitary insect, it hasn’t allowed researchers to investigate the genetic basis of complex social behavior in ants and bees. Now, a pair of studies published today in … Continue reading

Journal Club: Study of volcanic gases offers new fundamental insights into the Earth’s carbon cycle

To understand how the planet’s climate will evolve and has evolved over geologic time, scientists need to understand the Earth’s carbon cycle. In work recently published  in Science, researchers offer new insights into that cycle, upending calculations about just how … Continue reading

Journal Club: Antarctic cyanobacteria show no changes due to warming—yet

Captain Robert Scott’s Antarctic Discovery expedition took place over 100 years ago—and yet its participants recently racked up another contribution to science. Thanks to the samples of bacterial mats they collected from polar ponds—samples that were pressed, dried, and stored … Continue reading

Journal Club: Insights from 3-D images defy assumptions about how plant cells communicate

When plant cells communicate, plasmodesmata serve as crucial conduits. These channels cross cell walls, linking one cell to its neighbor. If a plant needs to grow larger or fight off a pathogen, molecular signals pass through plasmodesmata to keep cells … Continue reading

Journal Club: Mutation helps Zika virus evolve to more easily infect mosquitoes, spread infection

Scientists discovered the Zika virus over half a century ago. But it wasn’t until recent outbreaks in French Polynesia and South America that the mosquito-borne virus, now associated with Guillain-Barre syndrome in adults and microcephaly in newborn babies, reached epidemic … Continue reading

Journal Club: Engineered enzyme could streamline synthesis of nitrogen containing compounds

Researchers have re-engineered a bacterial enzyme to transform abundant alkanes into industrially important nitrogen-containing compounds that can be used to synthesize pharmaceuticals. In principle, the enzyme, now called P411CHA, could help streamline some methods for creating synthetic molecules, which often … Continue reading

Journal Club: Macrophages help regenerate ear parts in spiny mice

Salamander tails and fish fins are oft-cited examples of animals’ ability to regenerate a lost limb or organ. But one mammal—the African spiny mouse—has also emerged as a model of regenerative abilities. In a recent study, Ashley Seifert of the University … Continue reading

Journal Club: Metal-based compound shows rare specificity in early tests of its cancer-fighting capabilities

Many drugs used to fight cancer are based on metals. But such organometallic agents are generally thought to have low specificity for potential targets in cells, raising concerns that they may inflict collateral damage on healthy cells. Now scientists have … Continue reading
