Hong Kong offers a world of natural wonders tangible above and below the waves - National Geographic Explorer Jon Cybulski.
ALIVE WITH VIBRANT colors and home to a diverse
array of sealife, coral gardens are one of the most captivating
sights in the natural world. But for US-born, Hong Kong-based
historical ecologist and National Geographic Explorer Jonathan
Cybulski, coral also offers a window into the past.
“I like corals because they tell you something about the marine
ecosystem. They’re fragile creatures that can only exist in a
certain temperature and water quality state, and they’ve found a way
to be incredibly resilient in Hong Kong.”
Part of the coral biogeochemistry laboratory at the University of
Hong Kong, where he is pursuing his PhD, 31-year-old Cybulski
specializes in studying coral ecosystems to chart how they have
changed over time, and how that data can be used to better conserve
or restore them in the future. What surprises many people, he says,
is the prevalence and diversity of coral and other marine life that
can be seen in Hong Kong.

As North America's West Coast burns, scientists are concerned marine mammals will be harmed by smoke inhalation
Little research has been done on how marine mammals are affected by prolonged exposure to the smoke and chemicals released during wildfires, but if the aftermath of the Deepwater Horizon oil rig explosion in the Gulf of Mexico is any indicator, they could face serious health effects in the years to come

NOW SHE'S RECEIVING THE SAME MEDAL THE ASTRONAUTS ACCEPTED 51 YEARS. ago. Katherine Johnson, the trailblazing NASA mathematician, wins the Hubbard Medal for her calculations that made space exploration possible. Long before today’s technology was invented, Katherine Johnson was known as a computer. She calculated flight trajectories, by hand, for the United States space program.
