Opinion: Europe Is Sinking Biotech—Again
Scientifically groundless regulations could undercut the potential of gene-edited crops, much as they have with GMOs.

Viral Discoveries, 1929
The “mother of plant virology and serology,” Helen Purdy Beale, developed techniques to understand the nature of viruses that went unappreciated for decades.
The Literature

Invertebrate Density Influences Plant Flowering Times, Abundance
An experimental study explores how plant communities may be affected by future declines in invertebrate populations.

Retrons Help Bacteria Defend Themselves from Phages: Study
The mysterious DNA sequences appear to help bacterial cells spot when they’ve been infected with viruses—and prompt those cells to self-destruct.

Petunia’s Waxy Cuticle Regulates the Plant’s Sweet Smell
The thicker the flower petals’ cuticle, the more fragrance compounds the plant releases, according to a recent study.

Insects Might Be More Sensitive to Radiation than Thought
A study of bumble bees exposed to levels of radiation equivalent to those existing in Chernobyl hotspots shows that the insects’ reproduction takes a hit.

Specialized Leaves Keep This Plant’s Fruit Warm
A volunteer nature guide teamed up with researchers to discover a unique reproductive role for one vine’s leaves.

Infographic: How to Accelerate the Growth of Restored Corals
Our novel technique involves planting several small fragments of slow-growing corals onto dead coral heads. The fragments eventually fuse, forming a large colony in a fraction of the time that it takes wild corals to build reefs.

Infographic: Trans-kingdom Interactions in the Gut
Phages interact with bacteria and eukaryotic cells in ways that researchers suspect influence mammalian health.

Infographic: A Plant Cell’s Cuticle Helps Regulate Toxic Chemical Accumulation
Researchers found that thinning petunia cells’ cuticles caused them to slow production of volatile organic compounds.
Editorial

Feeling the Foundation
This year has started out in a fashion that is sadly similar to the way 2020 unspooled. But the steady pace of scientific discovery helps maintain our sense of hope.
