Understanding the genomic modifications in transgenic papaya

The transgenic papaya "SunUp" was developed in the 1990s and was widely publicized because of its ability to resist the papaya ringspot virus. Although researchers had identified the genomic sequence of SunUp by 2008, it ...

Engineers develop fast and accurate COVID-19 sensor

Engineers at Johns Hopkins University, supported in part by the U.S. National Science Foundation, have developed a COVID-19 sensor that addresses the limitations of the two most widely used types of COVID-19 tests: PCR tests ...

A perennial grass could mitigate climate change in the Midwest

Amid predictions of climate change driving up temperatures and causing more extreme heat in the Midwest, a new study led in part by University of Maryland researchers has found that growing one particular perennial grass ...

Monarch butterflies increasingly plagued by parasites

Monarch butterflies, among the most iconic insects in North America, are increasingly plagued by a debilitating parasite, a new analysis shows. The Journal of Animal Ecology published the findings by scientists at Emory University ...

A not-so-solid lake ice season

Mountain lakes provide freshwater for roughly half the world's population. Yet a shifting climate could impact the reliability of this resource by altering the temperature patterns that govern lake conditions and influence ...

Plant disease outbreaks may be curbed by periodic wildfires

Wildfires have made headlines worldwide in recent years. Evidence points to wildfires increasing in frequency and intensity across vulnerable ecosystems as climate change impacts grow more evident. But periodic wildfires ...

Hotspots shed light on 'flash drought' causes

Two Clemson University engineers say their research is the most comprehensive analysis so far of what causes flash drought, a weather phenomenon that has been blamed for billions of dollars in crop damage and increased wildfire ...
