rosy hydrangea
Hydrangea are synonymous with summer. These leafy shrubs filled with profuse balls of blooms grace boulevards, lawns, parks, and patios. Cut hydrangea blooms are also popular in floral arrangements. Hydrangea flowers appear in many colors: white, green, pink, lavender, and blue. Sometimes, one hydrangea bush might boast blooms of two different colors. Hydrangea flowers can even change color, going from white one year to blue the next.
How does this happen?
It all depends on the chemical composition of the soil in which the hydrangea grows–the acidity and the aluminum levels are key. Backyard gardeners have all sorts of home remedies to alter the soil composition under a hydrangea bush and thus change the color of the blooms. Some say a bed of pine needles will do the trick while others believe in burying rusty nails by the roots. The most reliable tactic, however, is to stop in a local garden store, ask the advice of a master gardener, and purchase the specialty fertilizer they suggest.

Sonic Booms Fired from the Reef by Douglas J. Lanzo

the coral-creviced crackling
of shrimp
If you’ve ever snorkeled over a reef and heard strange crackling sounds, chances are that you were tuning in to one of the most remarkable creatures of the reef: snapping shrimp.
As soon as a reef snapping shrimp spots its prey, such as a small goby, hermit crab or bristle worm, it springs into action, pulling back its upper claw into an open position akin to cocking the hammer of a pistol. Upon releasing a specialized, latching joint, its claw finger slams shut in less than a millisecond, ejecting water from its socket at speeds of up to 100 km/hour. The intense speed of this water jet shears the water apart, creating a cavitation bubble whose implosion produces a sonic shockwave of over 200 decibels in acoustic pressure, instantly killing the stunned prey.
As if these feats of physics were not enough, the shrimp’s snap also produces an intense burst of light called sonoluminescence whose temperature for a few nanoseconds approaches the temperature on the surface of the sun.

| Botanical name: | Prunus mume |
| Popular names: | Plum Blossom, Meihua (China) |
| Family: | Rosaceae |
| Origin: | Area round Yangtze River, spread to Japan, Korea and Vietnam |
| Habitat: | Found in sparse forests, at edge of trails up to 3,100m. Sunny position, fertile soil, no water logging, blossom subject to frost damage. |
The national flower of China, the Plum blossom, starts to flower in late winter, early spring. Colours range through white, pink and red. The blossom has a characteristic fragrance. In China there are over 300 recorded cultivars.
Plum blossom plays an important symbolic role in Confucianism and Daoism. It represents the Five Virtues: benevolence, righteousness, propriety, wisdom and trustworthiness. The trees often bloom in adverse conditions which perhaps explains the flowers’ association with resilience and perseverance.
In Chinese art and calligraphy this blossom is often celebrated. It is the subject of classical poetry in the work of Wang Anshi and Lin Bu.
