Increasing risk of invasive species colonization on marine debris      (via sciencedaily.com)     Original source 

A groundbreaking scientific study conducted along the Southeast coast of India has unearthed a pressing environmental concern -- the increasing risk of invasive species colonization on marine debris. The research delves into the critical interplay between plastic pollution and the introduction of non-indigenous organisms into Indian waters.

Mammalian cells may consume bacteria-killing viruses to promote cellular health      (via sciencedaily.com)     Original source 

Bacteriophages, also called phages, are viruses that infect and kill bacteria, their natural hosts. But from a macromolecular viewpoint, phages can be viewed as nutritionally enriched packets of nucleotides wrapped in an amino acid shell. A study suggests that mammalian cells internalize phages as a resource to promote cellular growth and survival.

Membrane transporter ensures mobility of sperm cells      (via sciencedaily.com)     Original source 

Special proteins -- known as membrane transporters -- are key to the mobility of sperm cells. A research team has, with the aid of cryo-electron microscopy, succeeded in decoding the structure of such a transporter and its mechanism. These findings will enable a better understanding of the molecular foundations of reproductive capacity and could, in the long term, contribute to developing new approaches to treating fertility disorders and new methods of specific contraception.

Defect in fruit fly respiratory system may provide insights into human aortic aneurysms      (via sciencedaily.com)     Original source 

A team of researchers has gained new insights into the respiratory system of fruit flies -- the so-called tracheal system -- which could be important for future research into aneurysms. Scientists carried out genetic, cell biological and biochemical studies on Drosophila embryos. They found that the cells in the fruit fly's tracheal system are connected to the extracellular matrix by the proteins Dumpy and Piopio.

Light, freshwater sticks to Greenland's east coast      (via sciencedaily.com)     Original source 

Meltwater that runs along the east coast of Greenland, hardly enters the open ocean before reaching the western side of the island.  In the changing climate, fresh water from Greenland and the Arctic could disrupt the circulation in the Atlantic Ocean.

Soft, living materials made with algae glow under stress      (via sciencedaily.com)     Original source 

Researchers have developed soft yet durable materials that glow in response to mechanical stress, such as compression, stretching or twisting. The materials derive their luminescence from single-celled algae known as dinoflagellates, which are embedded within the materials. The work was inspired by the bioluminescent waves caused by dinoflagellates during red tide events at San Diego's beaches.

Ancient sea monster remains reveal oldest mega-predatory pliosaur      (via sciencedaily.com)     Original source 

The fossils of a 170-million-year-old ancient marine reptile from the Age of Dinosaurs have been identified as the oldest-known mega-predatory pliosaur -- a group of ocean-dwelling reptiles closely related to the famous long-necked plesiosaurs. The findings are rare and add new knowledge to the evolution of plesiosaurs.

Moving muscle fibers with magnets 'programs' how they align within tissue      (via sciencedaily.com)     Original source 

Stimulating muscle fibers with magnets causes them to grow in the same direction, aligning muscle cells within tissue. The findings offer a simpler, less time-consuming way for medical researchers to program muscle cell alignment, which is strongly tied to healthy muscle function.

How cord-like aggregates of bacteria lead to tuberculosis infections      (via sciencedaily.com)     Original source 

The ability of Mycobacterium tuberculosis (MTB), a serious respiratory infection, to form snake-like cords was first noted nearly 80 years ago. Investigators report the biophysical mechanisms by which these cords form and demonstrate how several generations of dividing bacteria hang together to create these structures that enable resistance to antibiotics.

Soil carried on sea freight loaded with dangerous pests and diseases, research finds      (via sciencedaily.com)     Original source 

While sea freight is recognised as a pathway for the movement of exotic organisms, there is little research that has quantified the risk. Soil collected from the external surfaces of sea freight was found to support live microorganisms, worms, seeds and insects, including various regulated biosecurity organisms. The research confirms that shipping containers provide a pathway for the movement of exotic species.
