Genetically modified plant may boost supply of a powerful malaria drug
Using a DNA study and genetic engineering, researchers tripled the amount of an antimalarial compound naturally produced by sweet wormwood plants.
- Genetics
Cicadas on different schedules can hybridize
A new genetic study suggests that cicadas that emerge every 17 years have swapped genetic material with those that emerge every 13 years.

Heat waves are roasting reefs, but some corals may be resilient
The latest research on coral reefs clarifies the devastation of heat waves and looks at how coral might be able to adapt to warming waters.

Larger spleens may help ‘sea nomads’ stay underwater longer
The Bajau people of Southeast Asia have a gene variant associated with larger spleens, boosting their oxygen while breath-hold diving, researchers say.
- Climate
Rising CO2 levels might not be as good for plants as we thought
A 20-year experiment spots a reversal in the way two kinds of plants take up extra carbon from the atmosphere.

Male fruit flies enjoy ejaculation
Red light exposure made some genetically engineered fruit flies ejaculate, spurring a surge of a brain reward compound — and less desire for booze.

This plastic-gobbling enzyme just got an upgrade
Scientists tweaked a bacterial enzyme and made it more efficient in breaking down plastics found in polyester and plastic bottles.
- Oceans
Masses of shrimp and krill may play a huge role in mixing oceans
Hoards of migrating shrimp and krill can cause large-scale turbulence in the ocean, a new study suggests.
