Compound in nudibranchs toxic to cancer cell lines

Natural products play an invaluable role as a starting point in the drug discovery process, and plants and animals use many interesting biologically active natural products as chemical defence mechanisms against predators. Among marine organisms, many nudibranch gastropods are known to obtain toxins from what they are eating, such as sponges.

These toxins are used as chemical defences and bright colours to warn potential predators away,

Hurricanes have minimal impact on salt marshes

New research suggests that major hurricanes, though devastating to humans, have a minimal impact on salt marshes. The Boston University study reveals coastal ecosystems are more at risk of erosion by waves from moderate storms than from full-fledged tropical storms. In eight different marshes studied in the United States, Italy and Australia, extreme storm events accounted for less than one per cent of erosion.

Florida power plant closures may evict manatees

If current indicators follow suit, a large percentage Florida’s manatees may soon need a new winter home. Over the next 10-20 years, the state’s coal-fired power plants are expected to close. As 60 percent of the manatee population utilize the plants for refuge during winter, many will be forced to move to the natural springs such as those on the Crystal River. The springs’ constant 74-degree temperatures could soon be overcrowded with the gentle giants.

Fussy butterflyfish avoid corals touched by seaweed

A new study has revealed butterflyfish are particularly fussy about their food and shelter needs, avoiding corals that have come in contact with seaweed. Conducted by the University of Delaware, the study is the first to critically evaluate how coral-seaweed interactions will impact coral associated reef fishes, a key component of coral reef resilience.

Is There Still a Case for Open Circuit in Tech?

One thing about crystal ball gazing, it is a lot like looking down into the blue abyss while sitting in deco, with the sun’s rays streaming in and making a magical and inviting sight. To those who may not have experienced this yet, it is one of the most evocative and alluring sights that any diver—technical or sport—could ever see. It brings one closer to the water than one can explain in words.
