Environmental impacts of pot fishing — ScienceDaily

The global pot fishing industry could be having a greater impact on corals, sponges and other species found on the seabed than previously thought, according to new research.

Scientists from the University of Plymouth (UK) attached video cameras to pots used by crab and lobster fishermen off the south coast of England.

As the pots were lowered, and later recovered, they recorded any damage caused to the rocky reefs on the seabed and various ecologically important species which call them home.

The resulting footage showed that of the 18 species observed, 14 suffered damage as the pots were hauled from the seabed.

This included certain species — including pink sea fans, ross coral, Dead Man’s Fingers and boring sponges — recognised as indicators of general health in the marine environment.

The findings go against previous thinking around the damage caused by pot fishing to the seabed, with research carried out

A new study is sounding the alarm on the impact climate change could have on one of the world’s most vulnerable regions.


Michael McGlue, Pioneer Natural Resources Professor of Stratigraphy in the University of Kentucky Department of Earth and Environmental Sciences, and his team conducted the study at Lake Tanganyika—a major African fishery. The results, which published today in Science Advances, show how certain changes in climate may place the fishery at risk, potentially diminishing food resources for millions of people in this area of eastern Africa.

“Lake Tanganyika’s fish are a critically important resource for impoverished people from four nations (Tanzania, Democratic Republic of the Congo, Burundi and Zambia) and resilience

Serious Google Photos Problem Impacts Millions Of Users

Google Photos is a great place to keep a backup of all your smartphone pictures, but some Samsung users have recently discovered that the service can no-longer be trusted to keep their images safe.

MORE FROM FORBESGoogle’s Pixel Smartphones Have Serious New Problems

According to a report by Android Police, images created in Samsung’s Motion Photos format are no-longer saving correctly on Google Photos, causing data to be lost. 

Motion Photos enhance regular still shots by adding a short video clip, and sometimes audio, each time the shutter is clicked. Unfortunately, these audio and video elements are apparently being stripped out by Google Photos, leaving only the still image.

It’s not clear at this point whether Google Photos is simply failing to display the video content or whether it hasn’t been saved at all. This means Samsung users can’t currently trust

Two groups of tiny, delicate marine organisms, sea butterflies and sea angels, were found to be surprisingly resilient—having survived dramatic global climate change and Earth’s most recent mass extinction event 66 million years ago, according to research published this week in the Proceedings of the National Academy of Sciences led by Katja Peijnenburg from Naturalis Biodiversity Center in the Netherlands.


Sea butterflies and sea angels are pteropods, abundant, floating snails that spend their entire lives in the open ocean. A remarkable example of adaptation to life in the open ocean, these mesmerizing animals can have thin shells and a snail foot transformed into two wing-like structures that enable them to ‘fly’ through the water.

Unexpected wildfire emission impacts air quality worldwide

In lab studies of wildfire, nitrous acid seems like a minor actor, often underrepresented in atmospheric models. But in the real-world atmosphere, during wildfires, the chemical plays a leading role—spiking to levels significantly higher than scientists expected, driving increased ozone pollution and harming air quality, according to a new study led by the University of Colorado Boulder and the Belgian Institute for Space Aeronomy.


“We found nitrous acid levels in wildfire plumes worldwide are two to four times higher than expected,” said Rainer Volkamer, CIRES Fellow, professor of chemistry at CU Boulder and co-lead author on the Nature Geoscience study. “The chemical can ultimately drive the formation of lung- and crop-damaging ozone pollution downwind of fires.”

Nitrous acid in wildfire smoke is accelerating the formation of an oxidant, the hydroxyl radical or OH. Unexpectedly, nitrous acid was responsible for around 60 percent of OH
