Does DNA in the water tell us how many fish are there?
on July 3, 2020 at 1:49 pm
Researchers have developed a new non-invasive method to count individual fish by measuring the concentration of environmental DNA in the water, which could be applied for quantitative monitoring of aquatic ecosystems.
Rising water temperatures could endanger the mating of many fish species
on July 2, 2020 at 6:47 pm
In a new meta-study, experts have published ground-breaking findings on the effects of climate change for fish stock around the globe.
Marine algae from the Kiel Fjord discovered as a remedy against infections and skin cancer
on July 2, 2020 at 3:37 pm
Using state-of-the-art approaches coupled with bio- and cheminformatics and machine learning, researchers have succeeded in discovering new, bioactive components of the Baltic Sea Baltic Sea seaweed Fucus vesiculosus and its fungal symbiont against infectious bacteria or skin cancer.
New candidate for raw material synthesis through gene transfer
on July 2, 2020 at 3:36 pm
Cyanobacteria hardly need any nutrients and use the energy of sunlight. Bathers are familiar with these microorganisms as they often occur in waters. A group of researchers has discovered that the multicellular species Phormidium lacuna can be genetically modified by natural transformation and could thus produce substances such as ethanol or hydrogen.
Study confirms ultra music festival likely stressful to fish
on July 1, 2020 at 7:17 pm
A new study found that the Ultra Music Festival was likely stressful to toadfish.
Jellyfish-inspired soft robots can outswim their natural counterparts
on July 1, 2020 at 7:17 pm
Engineering researchers have developed soft robots inspired by jellyfish that can outswim their real-life counterparts. More practically, the new jellyfish-bots highlight a technique that uses pre-stressed polymers to make soft robots more powerful.
Microscope allows gentle, continuous imaging of light-sensitive corals
on June 30, 2020 at 8:15 pm
Many corals are sensitive to bright light, so capturing their dynamics with traditional microscopes is a challenge. To work around their photosensitivity, researchers developed a custom light-sheet microscope (the L-SPI) that allows gentle, non-invasive observation of corals and their polyps in detail over eight continuous hours, at high resolution.
New Zealand's ancient monster penguins had northern hemisphere doppelgangers
on June 30, 2020 at 7:57 pm
New Zealand's monster penguins that lived 62 million years ago had doppelgangers in Japan, the USA and Canada, a new study has found.
Research reveals fishing pressures affect tropical and temperate reefs differently
on June 30, 2020 at 1:22 pm
An international team of researchers focused on what can happen to ocean ecosystems when fishing pressure increases or decreases, and how this differs between tropical to temperate marine ecosystems. The team found ecosystems do not respond universally to fishing.
Historic floods reveal how salt marshes can protect us
on June 29, 2020 at 4:02 pm
By digging into major historic records of flood disasters, a research team reveals that the value of nature for flood defense has actually been evident for hundreds of years.
Bleaching affects aquarium corals, too
on June 29, 2020 at 4:01 pm
A world-first study examines the temperature thresholds of Australian aquarium corals and finds they are at risk under climate change.
Soft coral garden discovered in Greenland's deep sea
on June 29, 2020 at 1:00 pm
A deep-sea soft coral garden habitat has been discovered in Greenlandic waters using an innovative and low-cost deep-sea video camera built and deployed by the team.
First completely remote at-sea science expedition in Australia's coral sea marine park
on June 28, 2020 at 1:42 pm
Scientists working remotely with Schmidt Ocean Institute, one of the only at-sea science expeditions to continue operating during the global pandemic, have completed a first look at deep waters in the Coral Sea never before seen.
Unknown currents in Southern Ocean have been observed with help of seals
on June 26, 2020 at 3:47 pm
Using state-of-the-art ocean robots and scientific sensors attached to seals, researchers have for the first time observed small and energetic ocean currents in the Southern Ocean. The currents are critical at controlling the amount of heat and carbon moving between the ocean and the atmosphere -- information vital for understanding our global climate and how it may change in the future.
Maryland offshore wind farm could become stop-over for migrating sturgeon, striped bass
on June 26, 2020 at 1:27 pm
For the endangered Atlantic sturgeon and the commercially important striped bass, the Delaware-Maryland-Virginia coastal shelf serves as an important spring and fall migratory route. Researchers suggest that the development of wind farms on the DelMarVa coastal shelf may alter the migratory behavior of these fish as new wind turbines in this otherwise featureless region could create habitat around which fish linger.
Microbiome of anticancer compound-producing marine invertebrate
on June 25, 2020 at 8:22 pm
Could the cure for melanoma - the most dangerous type of skin cancer -- be a compound derived from a marine invertebrate that lives at the bottom of the ocean? A group of scientists think so, and are looking to the microbiome of an Antarctic ascidian called Synoicum adareanum to better understand the possibilities for development of a melanoma-specific drug.
Dolphins learn foraging skills from peers
on June 25, 2020 at 3:59 pm
Dolphins can learn new skills from their fellow dolphins. New findings show that dolphins are not only capable of learning new ways to catch prey, but they are also motivated to learn from peers, not just from their mothers, the researchers say.
Puget Sound eelgrass beds create a 'halo' with fewer harmful algae, new method shows
on June 24, 2020 at 9:20 pm
DNA clues show that eelgrass growing underwater along Washington state shorelines is associated with fewer of the single-celled algae that produce harmful toxins in shellfish. Observations show this effect extends 45 feet beyond the edge of the eelgrass bed.
Effects from low-level concentrations of harmful chemicals preserved in three generations of fish
on June 24, 2020 at 7:15 pm
Fish exposed to very low levels of chemicals commonly found in waterways can pass the impacts on to future generations that were never directly exposed to the chemicals, according to researchers.
Four new species of giant single-celled organisms discovered on Pacific seafloor
on June 24, 2020 at 2:00 pm
Two new genera and four new species of giant, single-celled xenophyophores (protozoans belonging to a group called the foraminifera) were discovered in the deep Pacific Ocean.
