Journal Club: Carbon payments could prove more profitable than mining or logging for some nations

Logging, mining, and other activities plow through the tropical forests of developing countries, releasing 10 to 18 percent of the greenhouse gas emissions that drive climate change. One proposed solution is for wealthy countries to pay developing nations to keep … Continue reading

Journal club: A simple model to help identify which species might become invasive

Invasive species are a major driver of global biodiversity loss. Now researchers have developed a simple model that can quickly predict which species are likely to become established outside their native environment. The team recently reported in the Proceedings of … Continue reading

Journal Club: Low-intensity focused ultrasound shows promise as tool to probe deep brain function

To study the brain’s networks of neurons, neuroscientists typically alter the activity in one area, and observe the cascade of effects on others—something like unscrewing one bulb in a string of Christmas lights and observing as others go dim. But … Continue reading

Journal Club: Plants load extracellular vesicles with a new class of RNAs

A recent study in The Plant Cell found that plants release extracellular vesicles carrying a new class of RNA molecules, named “tiny RNAs.” The findings are among the first to reveal the contents of these vesicles, and may hint at … Continue reading

Journal Club: Pinpointing theory of mind deficiencies in autism

Around age four, preschoolers learn that other people have unique thoughts and feelings, an inner life. These children start to be able to predict a person’s behavior based on that understanding. They start developing theory of mind (ToM). That developmental … Continue reading

Journal Club: Seedbanks, meant to safeguard key plant species, need to enhance their diversity

Humanity’s last hope could someday rest on a humble seed, tucked away in the cool and dark of a collection. Seed collections, called seedbanks or seed genebanks, store millions of grains, nuts, and kernels in baggies and plastic bins, meant … Continue reading

Journal Club: Amoeba have long-distance preference for certain bacteria, pointing to other cell-sensing insights

How does the microscopic amoeba track down prey in the vastness of the forest floor? Ample research on the soil amoeba Dicytostelium discoideum, affectionately called “Dicty” by researchers, has provided some clues. But the mechanisms behind long-distance sensing of bacterial … Continue reading

Journal Club: The simple physics of stretching rubber bands surprises researchers, offers up potential application

Movie 2 – Classic strech dominated recoil When the researchers turned their high-speed camera on a rubber band being released, they discovered, to their surprise, that the shape of the back of the rubber band was round (top clip), and … Continue reading

Journal Club: Newly solved structure of a GABA receptor could offer drug design insights

Neurons message each other with the help of excitatory or inhibitory neurotransmitters. But to actually deliver those messages, the neurotransmitters must dock with protein receptors embedded in the cell membranes of adjacent neurons. Of particular interest in the human brain … Continue reading

Journal Club: Ion channel puts the squeeze on blood vessels, affecting blood pressure

Blood pressure is exquisitely regulated to respond to our physiological state. Stress raises blood pressure. Simply stand up, and the arteries constrict to maintain pressure. New findings in mice show how a protein called PKD2 helps regulate blood pressure by … Continue reading
