Howard Berg, director of the Imaging and Microscopy Facility at the Donald Danforth Plant Science Center and his collaborators have discovered a previously unknown compartment within these symbiotic cortical root cells that could be important for nutrient exchange and molecular communication between the symbiotic partners.
Retailers didn't realize offering different prices to consumers actually could backfire — until researchers from Washington University in St. Louis, UCLA and Alibaba had the data to show it. Using data from 100 million Alibaba customers who shopped at 11,000 retailers over 1 month in 2016, the researchers looked at consumers who left products — carrying special price promotions — untouched in their online shopping carts for more than 24 hours. The results were surprising.
Two groups of sRNAs are abundant during development of pollen in the anthers. One of these pathways for sRNA production, previously believed present in grasses and related monocots, has now been demonstrated to be present widely in the flowering plants, evolved over 200 million years ago, and is arguably one of the evolutionary innovations that made them so successful.
A drop of rainwater that falls on a cassava field in Uganda takes a different path than one that falls 500 miles east in Somalia. Knowing where rain comes from now, and where it might come from under future climate scenarios, is important for the millions of people who rely on subsistence agriculture to survive. Research from Washington University in St Louis offers a new tool for tracking the rainwater race.

Researchers at Washington University School of Medicine in St. Louis have discovered clues to a particularly deadly form of rejection that can follow lung transplantation. Called antibody-mediated rejection, the condition remains impervious to available treatments and difficult to diagnose. The researchers have identified, in mice, a process that may prevent the condition and lead to possible therapies to treat it.
With paper-weight wings and spindly legs, the mosquito hardly seems built to handle the cold. The secret to its survival is eggs built to withstand freezing temperatures. Even if some eggs die off during extreme cold, mosquito populations rebound quickly. The same holds true for ticks that can wait out a cold snap far below a forest’s layer of leaves.
