A new study from the ARC Centre of Excellence for Coral Reef Studies found that corals can survive the early stages of development under challenging conditions, like those that will come as a result of carbon emissions. Most research regarding the health of coral reefs and ocean acidification focuses on adult corals, but until now the effects of ocean acidification on young corals was unclear. This research does not suggest that acidification is not a threat to corals, it just highlights the fact that not all stages of development will be equally affected.

Eating salmon once a week ‘reduces risk of rheumatoid arthritis by half’

It’s been said before that eating more fish is good for you but now a new study reveals just how good. A study found that eating oily fish such as salmon at least once a week could cut your risk of developing rheumatoid arthritis in half. The same benefits could also be achieved by eating four portions of leaner fish (like cod) every week. The benefits are attributed to omega-3 fatty acids which are thought to block the body’s response to inflammation and are present in higher concentrations in oily fish like salmon, mackerel, herring, sardines and trout.

Hammerhead shark gives birth on beach in Florida as stunned crowd looks on

Last weekend, beachgoers at St. Andrews State Park in Florida witnessed something bizarre. A fishermen (accidentally, we hope) hooked a hammerhead shark that was swimming close to shore. With the help of a few others, the man pulled the shark out of the water up the beach. Park officials assume (and again, we hope) that he was simply trying to retrieve the hook from the shark, but that’s when something strange happened. The shark started giving birth to lots of little hammerheads. Unfortunately, the shark was too stressed and died, but you can see her pups wiggling their way back into the water.
