Unchecked Global Emissions on Course To Trigger Mass Extinction of Marine Life

Unchecked Global Emissions on Course To Trigger Mass Extinction of Marine Life

Princeton University researchers reported in a new study that unless greenhouse gas emissions are curbed, marine biodiversity may be on track to plummet to levels not seen since the extinction of the dinosaurs. The scientists modeled future marine biodiversity under projected climate scenarios and found that species such as dolphinfish (shown) would be imperiled as … Read more

Innovative Experimental Study Provides New Insights Into the Genetics of Heritable Traits

Genetic Codes Illustration

Researchers published a new study that provides insight into the genetic basis of heritable traits using an unusual experimental paradigm that included 240,000 strains of brewer’s yeast descended from two common “parents.” An analysis of 240,000 yeast strains reveals the complex interplay between large-impact genetic markers and genetic background. Enormous dataset presents unprecedented detail of … Read more

Stanford Scientists Have Produced the First Complete Picture of an Elusive Quasiparticle

Quantum Bits QuBits Atomic Particle Physics

Scientists have taken a significant step in understanding these whirling quasiparticles and putting them to work in future semiconductor technologies. Researchers reported that they have imaged the exciton’s electron and hole for the first time, revealing how excitons may be trapped in dense, stable arrays. According to the scientists, the findings have significant implications for … Read more
