Clownfish spend their entire lives nestling in the protective tentacles of host anemones, but new research shows that as babies they sometimes travel hundreds of kilometres across the open ocean. Although the process of long-distance dispersal by reef fish has been predicted, this is the first time that the high level exchange of offspring between distant populations has been observed.

Dr Steve Simpson, Senior Lecturer in Marine Biology and Global Change in Biosciences at the University of Exeter, and colleagues from the Australian Research Council Centre of Excellence for Coral Reef Studies (ARC COE CRS), Sultan Qaboos University (Oman) and the Centre National de la Recherche Scientifique (France) have published their findings on the dispersal of Omani clownfish larvae in the journal PLOS ONE.

Dissolution or creation of huge gypsum deposits changed sulfate content of the oceans

Scientists have discovered a potential cause of Earth’s “icehouse climate” cooling trend of the past 45 million years. It has everything to do with the chemistry of the world’s oceans.

“Seawater chemistry is characterized by long phases of stability, which are interrupted by short intervals of rapid change,” says geoscientist Ulrich Wortmann of the University of Toronto, lead author of a paper reporting the results and published this week in the journal Science.

“We’ve established a new framework that helps us better interpret evolutionary trends and climate change over long periods of time. The study focuses on the past 130 million years, but similar interactions have likely occurred through the past 500 million years.” (more…)

Student winners from across the globe, including United States and Thailand, are honored at the 10th anniversary of the Imagine Cup.

SYDNEY — July 10, 2012 — Microsoft Corp. announced the winners of the 10th annual Imagine Cup, the world’s premier student technology competition, honoring student technology innovations that address the world’s toughest problems. The winning Software Design project developed by Ukrainian Team quadSquad allows deaf individuals to communicate verbally using custom-designed sensory gloves and a smartphone application to translate sign language gestures into speech. Games focused on the environment from Thailand team TANG Thai and math education from U.S. team Drexel Dragons won the two Game Design competitions.

The Imagine Cup 2012 competition winners were announced tonight at the Imagine Cup World Festival and Awards Ceremony at the Sydney Convention and Exhibition Centre, in front of 106 student teams. The event was the culmination of a five-day celebration of technology, teamwork and innovation. (more…)

*Disruption of wind shear enables stronger storms*

Pollution is making Arabian Sea cyclones more intense, according to a study in this week’s issue of the journal Nature.

Traditionally, prevailing wind shear patterns prohibit cyclones in the Arabian Sea from becoming major storms.

The Nature paper suggests that weakening winds have enabled the formation of stronger cyclones in recent years–including storms in 2007 and 2010 that were the first recorded storms to enter the Gulf of Oman. (more…)
