New tools needed to prevent plant disease pandemics

Plant diseases don't stop at a nation's borders and miles of oceans don't prevent their spread, either. That's why plant disease surveillance, improved plant disease detection systems and predictive plant disease modeling—integrated ...

Bumble bee disease, reproduction shaped by flowering strip plants

Flowering strips—pollinator-friendly rows of plants that increase foraging habitat for bees—can help offset pollinator decline but may also bring risks of higher pathogen infection rates for pollinators foraging in those ...

We now know how insects and bacteria control ice

Contrary to what you may have been taught, water doesn't always freeze to ice at 32 degrees F (zero degrees C). Knowing, or controlling, at what temperature water will freeze (starting with a process called nucleation) is ...

Diphthamide is an Achilles heel shared by both plants and animals

The biomolecule diphthamide is essential for the proper formation of proteins in cells. When humans are infected with diphtheria, diphthamide is altered by the diphtheria toxin so that life-threatening complications can arise ...

How plants' threat-detection mechanisms raise the alarm

New work led by Carnegie's Zhiyong Wang untangles a complex cellular signaling process that underpins plants' ability to balance expending energy on growth and defending themselves from pathogens. These findings, published ...
