Ancient giant dolphin discovered in the Amazon      (via sciencedaily.com)     Original source 

Measuring between 3 to 3.5 meters, 16 million years old: Paleontologists have announced the discovery of a new species of freshwater dolphin in the Peruvian Amazon region. Surprisingly, its closest living relatives can be found in the river dolphins of South Asia.

Bacteria subtype linked to growth in up to 50% of human colorectal cancers      (via sciencedaily.com)     Original source 

Researchers have found that a specific subtype of a microbe commonly found in the mouth is able to travel to the gut and grow within colorectal cancer tumors. This microbe is also a culprit for driving cancer progression and leads to poorer patient outcomes after cancer treatment. The findings could help improve therapeutic approaches and early screening methods for colorectal cancer, which is the second most common cause of cancer deaths in adults in the U.S. according to the American Cancer Society.

Craving snacks after a meal? It might be food-seeking neurons, not an overactive appetite      (via sciencedaily.com)     Original source 

Psychologists have discovered a circuit in the brain of mice that makes them crave food and seek it out, even when they are not hungry. When stimulated, this cluster of cells propels mice to forage vigorously and to prefer fatty and pleasurable foods like chocolate over healthier foods like carrots.

Fish fed to farmed salmon should be part of our diet, too, study suggests      (via sciencedaily.com)     Original source 

Scientists found that farmed salmon production leads to an overall loss of essential dietary nutrients. They say that eating more wild 'feed' species directly could benefit our health while reducing aquaculture demand for finite marine resources.

Experts warn climate change will fuel spread of infectious diseases      (via sciencedaily.com)     Original source 

Infectious diseases specialists call the medical field to be ready to deal with the impact of climate change on spreading diseases, such as malaria, Valley fever, E. coli and Lyme disease.

There are large accumulations of plastics in the ocean, even outside so-called garbage patch      (via sciencedaily.com)     Original source 

When plastic ends up in the ocean, it gradually weathers and disintegrates into small particles. If marine animals ingest these particles, their health can be severely affected. Large accumulations of plastic can therefore disrupt the biological balance of marine ecosystems. But which areas are particularly affected?

A protein found in human sweat may protect against Lyme disease      (via sciencedaily.com)     Original source 

Human sweat contains a protein that may protect against Lyme disease. About one-third of the population carries a genetic variant of this protein that is associated with Lyme disease in genome-wide association studies.

Genes identified that allow bacteria to thrive despite toxic heavy metal in soil      (via sciencedaily.com)     Original source 

Some soil bacteria can acquire sets of genes that enable them to pump the heavy metal nickel out of their systems, a study has found. This enables the bacteria to not only thrive in otherwise toxic soils but help plants grow there as well. A research team pinpointed a set of genes in wild soil bacteria that allows them to do this in serpentine soils which have naturally high concentrations of toxic nickel. The genetic discovery could help inform future bioremediation efforts that seek to return plants to polluted soils.

Industrial societies losing healthy gut microbes      (via sciencedaily.com)     Original source 

Our eating habits in industrialized societies are far removed from those of ancient humans. This is impacting our intestinal flora, it seems, as newly discovered cellulose degrading bacteria are being lost from the human gut microbiome, especially in industrial societies.

New discovery concerning occurrence of antibiotic resistance      (via sciencedaily.com)     Original source 

A new study shows how heteroresistance, a transient resistance common in many bacteria, can act as a precursor to the development of antibiotic resistance.

A wetter world recorded in Australian coral colony      (via sciencedaily.com)     Original source 

When climate scientists look to the future to determine what the effects of climate change may be, they use computer models to simulate potential outcomes such as how precipitation will change in a warming world. Some scientists are also looking at something a little more tangible: coral.

Fish species that move rapidly toward the poles due to global warming decline in abundance, study finds      (via sciencedaily.com)     Original source 

A new study has found a decline in the abundance of marine fish species that move rapidly toward the poles to escape rising sea temperatures. The researchers explain that many animal species are currently moving toward cooler regions as a result of global warming, but the velocity of such range shifts varies greatly for different species. Examining thousands of populations from almost 150 fish species, the researchers show that contrary to the prevailing view, rapid range shifts coincide with widescale population declines.

Newborn piglets serve as a model for studying influenza      (via sciencedaily.com)     Original source 

Although prevention and treatment strategies are available for influenza, they are not sufficient for vulnerable populations such as young children and newborns. A team of researchers has studied newborn piglets to better understand the progression of influenza infections.

Engineers measure pH in cell condensates      (via sciencedaily.com)     Original source 

In a first for the condensate field, researchers have figured out how nucleolar sub-structures are assembled. This organization gives rise to unique pH profiles within nucleoli, which they measured and compared with the pH of nearby non-nucleolar condensates including nuclear speckles and Cajal bodies.

'Noisy' roundworm brains give rise to individuality      (via sciencedaily.com)     Original source 

Research has demonstrated individual differences in and successfully extracted commonalities from the whole-brain activity of roundworms. The researchers also found that computer simulations based on the whole-brain activity of roundworms more accurately reflect real-brain activity when they include so-called 'noise,' or probabilistic elements.

Gut bacteria make neurotransmitters to shape the newborn immune system      (via sciencedaily.com)     Original source 

Investigators discovered that unique bacteria colonize the gut shortly after birth and make the neurotransmitter serotonin to educate gut immune cells. This prevents allergic reactions to food and the bacteria themselves during early development.
