We summarize the week's scientific breakthroughs every Thursday.
- Genetics
Microbe and human genes influence stomach cancer risk
When genes of the bacterium and its human host evolve together, the strain is less harmful than that same strain in a person whose ancestors didn't encounter that particular microbe.
- Health & Medicine
Green tea may sabotage blood pressure medication
Antioxidants in drink may keep intestinal cells from taking up drug.

Caffeine may improve memory
Taking the stimulant after learning new information boosted people’s recall the next day.
- Plants
Bladderwort opens wide
Under a microscope, the tiny trap of a carnivorous plant becomes an impressive gaping maw.
- Agriculture
Sweet potato weevils have favorite colors
When it comes to eradicating the sweet potato weevil, the devil is in the colorful details.

Tomorrow’s catch
A biologist who formerly applied his mathematical talents in finance has developed new ways of predicting the ups and downs of fish populations.
- Life
Marine microbes shed packets of DNA, nutrients
The world’s most abundant marine microorganism, the photosynthetic bacteria Prochlorococcus, spits out nutrient-rich vesicles into ocean waters, perhaps for genetic exchange or as a survival mechanism.
- Neuroscience
A schizophrenia drug turns on protein factories in cells
Haloperidol reshapes neurons, which might explain how the medicine works.
- Animals
Finally, evidence that a starfish’s eyes let it see
The sea star’s vision isn’t great, but it’s good enough to help the animal find its way home.
