Nitrogen-fixing bacteria talk to soybean roots via tiny RNAs, suggesting new avenue to improve yields

In order for soybean plants to get their necessary dose of nitrogen, they partner with bacteria called rhizobia, which can convert atmospheric nitrogen into organic forms the plant can use. But scientists don’t have the full picture of what facilitates … Continue reading

New protein structure reveals hotspot for cystic fibrosis drug binding

  The newly revealed structure of a cystic fibrosis drug, captured in tandem with its target channel protein, could help scientists design better medications for the condition. Cystic fibrosis results from mutations in the gene for the cystic fibrosis transmembrane … Continue reading

Journal Club: Psychological tasks in the lab are poor predictors of real-world self-regulation

Skipping dessert to stay healthy, saving money for a rainy day, not shouting at your boss even when there might be good reason—psychologists group these and other human behaviors under the large umbrella of “self-regulation.” That is, despite the near-term … Continue reading

Journal Club: Neurons fire in sync, helping elucidate the biological basis of learning

Our brains change as we learn. But how exactly does a cluster of neurons change their activity or connections? It seems the phenomenon is due, at least in part, to neurons starting to fire in sync, according to a recent … Continue reading

Journal Club: Understanding how a plant makes a hook could someday improve crops

This spring, as the first shoots of new plants emerge from the soil, many are bent over in a hook. This simple act protects the fragile stem tip and leaves as the sprout pokes up through the dirt. But how … Continue reading

Journal Club: Key protein family helps govern sense of touch in both plants and animals

Compared to their knowledge of other senses, scientists know relatively little about how cells sense touch. A newly confirmed family of mechanosensors, comprising more than a dozen members and present in both plants and animals, is an important step toward … Continue reading

Journal Club: Researchers catch the mouse brain in the act of learning something new

Neurobiologists have captured, for the first time, the moment in a mouse’s brain when it first learns something new: in this case, that a beep signals a delicious droplet of sugar water. The results, recently reported in Nature Neuroscience, support a famous … Continue reading

Journal Club: Bioengineers build a tiny heart ventricle to better understand heart disease and treatment

Bioengineer Kit Parker wants to build replacement hearts for children born with heart defects. Although that goal remains a long way off, Parker recently took a step in that direction by assembling a 1:250 scale model of the human left … Continue reading

Journal Club: Giving the brain something to do highlights the circuitry of smarts

Scientists conducting neuroimaging studies hope that their MRI scans will offer up patterns that predict traits related to intelligence, personality, disease, or even offer insights into a patient’s clinical symptoms or their chances of responding to a drug. But according … Continue reading
