Love links
Pollutant-gobblers
Fuelled by alcohol
Grafting proteins
Sooty clues
Garlic wards off TB
Vitamin C helps smokers
Plastic is good
Lead on the palate
Zap the bacteria
Decoding life
Plants as toxin purifiers
In their disposable cups
Summertime blues
Cleaner air
Forever fresh
Miniature biosphere
Can't stand the smell
Helping bacteria float
A hint from cars
Gutsy brains
