Journal Club: Brain scans and behavior suggest oxytocin can change perceptions of fairness

Some people are more generous in social situations—offering to cover the dinner bill for example. Others are more individualistic, preferring to keep resources for themselves. A recent study in Nature Neuroscience finds that perceptions of fairness vary from person-to-person based … Continue reading

Journal Club: Tumors create an acidic environment that helps them invade surrounding tissues

Cancer cells tend to turn their extracellular environment acidic, thus helping these rogue cells thrive while creating a hostile environment for normal ones. Acidosis promotes tumor growth, metastasis and drug resistance, while helping tumor cells evade the immune system. But … 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: 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
