How rabies virus moves through nerve cells, and how it might be stopped

Cells in red against black background

To successfully infect its host, the rabies virus must move from the nerve ending to the nerve cell body where it can replicate. In a study published July 20 in the journal PLoS Pathogens, researchers from Princeton University reveal that the rabies virus moves differently compared to other neuron-invading viruses and that its journey can … Continue reading How rabies virus moves through nerve cells, and how it might be stopped

A valley so low: Electrons congregate in ways that may be useful to “valleytronics”

Yellow swirling ellipses against a blue background

A Princeton University-led study has revealed an emergent electronic behavior on the surface of bismuth crystals that could lead to insights on the growing area of technology known as "valleytronics." The term refers to energy valleys that form in crystals and that can trap single electrons. These valleys potentially could be used to store information, … Continue reading A valley so low: Electrons congregate in ways that may be useful to “valleytronics”

Genetically engineered mice could boost fight against aggressive hepatitis

Article provided by the Department of Molecular Biology Hepatitis delta virus (HDV) causes the most aggressive form of viral hepatitis in humans, putting at least 20 million people worldwide at risk of developing liver fibrosis, cirrhosis, and liver cancer. Efforts to develop effective treatments against HDV have been hampered by the fact that laboratory mice … Continue reading Genetically engineered mice could boost fight against aggressive hepatitis

Novel insulators with conducting edges

Current flowing on the edges

Article courtesy of the University of Zurich An international team including scientists at Princeton University is researching a new class of materials: higher-order topological insulators. The edges of these crystalline solids conduct electric current without dissipation, while the rest of the crystal remains insulating. These materials could be useful for applications in semiconductor technology and … Continue reading Novel insulators with conducting edges

Half a degree more global warming could flood out 5 million more people

Car in water

By Liz Fuller-Wright, Office of Communications The 2015 Paris climate agreement sought to stabilize global temperatures by limiting warming to well below 2.0 degrees Celsius above pre-industrial levels and to pursue limiting warming even further, to 1.5 C. To quantify what that would mean for people living in coastal areas, a group of researchers employed … Continue reading Half a degree more global warming could flood out 5 million more people

Birds and beans: Which type of coffee is best for bird diversity?

green coffee beans

Article courtesy of Stephen Sautner, Wildlife Conservation Society It’s an age-old debate for coffee lovers.  Which is better: Arabica beans with their sweeter, softer taste, or the bold, deep flavor of Robusta beans? A new study by the Wildlife Conservation Society (WCS), Princeton University, and the University of Wisconsin-Madison appearing in the journal Scientific Reports … Continue reading Birds and beans: Which type of coffee is best for bird diversity?

Genetic instructions from mom set the pattern for embryonic development

Micrograph of a zebrafish organ called the Kupffer's vesicle

By the Department of Molecular Biology A new study indicates an essential role for a maternally inherited gene in embryonic development. The study found that zebrafish that failed to inherit specific genetic instructions from mom developed fatal defects earlier in development, even if the fish could make their own version of the gene. The study … Continue reading Genetic instructions from mom set the pattern for embryonic development

Spotting the spin of the Majorana fermion under the microscope

By Catherine Zandonella, Office of the Dean for Research Researchers at Princeton University have detected a unique quantum property of an elusive particle notable for behaving simultaneously like matter and antimatter. The particle, known as the Majorana fermion, is prized by researchers for its potential to open the doors to new quantum computing possibilities. In … Continue reading Spotting the spin of the Majorana fermion under the microscope

Researchers find an alternative mode of bacterial quorum sensing

By the Department of Molecular Biology Whether growing in a puddle of dirty water or inside the human body, large groups of bacteria must coordinate their behavior to perform essential tasks that they would not be able to carry out individually. Bacteria achieve this coordination through a process called quorum sensing in which the microorganisms … Continue reading Researchers find an alternative mode of bacterial quorum sensing

An immune signaling pathway for control of Yellow Fever Virus infection

By the Department of Molecular Biology Princeton University researchers have uncovered a critical role for a new immune signaling pathway in controlling infection by the flavivirus Yellow Fever Virus (YFV).  The paper describing this discovery was published today in the journal mBio. Infection with YFV causes a devastating illness with a mortality rate of up … Continue reading An immune signaling pathway for control of Yellow Fever Virus infection
