WashU Expert: Ingredients for a virus to become a pandemic
In this video, Washington University in St. Louis’ Michael Vahey discusses what it takes for a virus such as the coronavirus to reach pandemic status.
Collaboration lets researchers ‘read’ proteins for new properties
A collaboration between the McKelvey School of Engineering and St. Jude Children’s Research Hospital uncovers the underlying rules that, when broken, contribute to neurodegenerative diseases such as ALS.
Grain traits traced to ‘dark matter’ of rice genome
Researchers from Washington University in St. Louis and the Chinese Academy of Agricultural Sciences discovered that rice domestication relied on selection for traits determined by a poorly understood portion of the rice genome.
And then there was light
New research from Washington University in St. Louis provides insight into how proteins called phytochromes sense light and contribute to how plants grow. Biologists used sophisticated techniques to structurally define the sequence of events that support the transition between light- and dark-adapted states.
Four ways to curb light pollution, save bugs
Want to help stop the decline of our insect friends? A new publication from Brett Seymoure in Arts & Sciences shows how artificial light at night negatively impacts thousands of species that have evolved to use light levels as cues for courtship, foraging and navigation.
Straight from the source
Arpita Bose, assistant professor of biology in Arts & Sciences, has published new work that reveals how one kind of bacteria “eats” electricity by pulling in electrons straight from an electrode source. The research is published Nov. 5 in mBio.
WashU Expert: This year, let’s make standard time permanent
A Washington University in St. Louis expert on circadian rhythms says the country should be on standard time permanently. The science behind the choice is clear: standard time is better in terms of sleep, cardiac function, weight, cancer risk and alcohol and tobacco consumption.
NSF funds research on nitrogen fixation
Himadri B. Pakrasi, professor of biology in Arts & Sciences and director of InCEES, was recently awarded a $1.2-million grant for a collaborative study of cyanobacteria with the ultimate purpose of producing nitrogen-fixing crop plants.
Washington People: Stan Braude
Stan Braude, professor of practice in biology, is a talented teacher who instills in his students the skills they need to prepare for life outside of Washington University. Take it from his students, though — because if you ask him, he will give all the credit to Joe (his St. Bernard).
Understanding criticality and the brain’s neural networks
New research from Washington University in St. Louis confirms that the brain tunes itself to a point where it is as excitable as it can be without tipping into disorder, similar to a phase transition. The new research from Keith Hengen, assistant professor of biology in Arts & Sciences, is published Oct. 7 in the journal Neuron.
