Let's prepare now so farming insects as food is environmentally friendly, say scientists

EurekAlert! - Dom, 01/13/2019 - 23:00
As whole-roasted crickets gain traction as a protein-rich snack and restaurants experiment with mealworms on the menu, there's still 'an overwhelming lack of knowledge' concerning the ecological sustainability of the emerging, multi-million-dollar insects-as-food industry, say researchers at the Swedish University of Agricultural Sciences. In an opinion article published Jan. 14 in the journal Trends in Ecology & Evolution, they explore unanswered questions around insect rearing, safety, and environmental impacts.

Conversion of breast cancer cells into fat cells impedes the formation of metastases

EurekAlert! - Dom, 01/13/2019 - 23:00
An innovative combination therapy can force malignant breast cancer cells to turn into fat cells. This can be used to prevent the formation of metastases in mice, as researchers at the University of Basel's Department of Biomedicine recently reported in the journal Cancer Cell.

Marine bacterium sheds light on control of toxic metals

EurekAlert! - Dom, 01/13/2019 - 23:00
An ocean-dwelling bacterium has provided fresh insights into how cells protect themselves from the toxic effects of metal ions such as iron and copper.Although essential to life, metal ions can also generate reactive oxygen species (ROS) -- highly reactive molecules that damage cells as they try to form bonds with other molecules. In humans, reactive oxygen species are linked to ageing and also to diseases such as cancers.

A little weed may change the teenage brain

EurekAlert! - Dom, 01/13/2019 - 23:00
Teenagers who report using recreational marijuana just once or twice display increased volume of numerous brain regions, according to a study of 14-year-olds from Ireland, England, France, and Germany. The research, published in JNeurosci, warrants further study of low-level cannabis use among adolescents amid changing societal attitudes toward the drug.

Memory of last meal influences when, how much rats eat next

EurekAlert! - Dom, 01/13/2019 - 23:00
Researchers have identified cells in the brains of male rats that appear to control future food intake by preserving memories of past meals. The study, published in eNeuro, lends support to the idea of boosting meal memories as a strategy for managing overeating.

Central Texas salamanders, including newly identified species, at risk of extinction

EurekAlert! - Dom, 01/13/2019 - 23:00
Biologists at The University of Texas at Austin have discovered three new species of groundwater salamander in Central Texas, including one living west of Austin that they say is critically endangered. They also determined that an already known salamander species near Georgetown is much more endangered than previously thought. They warn that more severe droughts caused by climate change and increasing water use in Central Texas have left groundwater salamanders 'highly vulnerable to extinction.'

Using genomic data, NYU Abu Dhabi researchers unlock history of North African date palm

EurekAlert! - Dom, 01/13/2019 - 23:00
Genome analysis reveals that North African date palms are a hybrid between cultivated date palms from the Middle East and a different, wild species of palm that grows on the island of Crete and in small areas of Southern Turkey. These findings, the result of research at NYU Abu Dhabi's Center for Genomics and Systems Biology (NYUAD CGSB), shed new light on the evolutionary history of one of the crop.

Diving deeper into developmental dyslexia

EurekAlert! - Dom, 01/13/2019 - 23:00
Men with dyslexia have altered structural connections between the thalamus and auditory cortex on the left side of the brain, new research published in JNeurosci reveals. The study extends similar observations of the dyslexic visual system and highlights the importance of early sensory processing for reading proficiency.

Invest in a single national electronic health record for primary care to benefit Canadians

EurekAlert! - Dom, 01/13/2019 - 23:00
Canada should invest in a single national electronic health record for primary care to improve the health of Canadians, argues an editorial in CMAJ.

Breast cancer cells in mice tricked into turning into fat cells

EurekAlert! - Dom, 01/13/2019 - 23:00
As cancer cells respond to cues in their microenvironment, they can enter a highly plastic state in which they are susceptible to transdifferentiation into a different type of cell. Researchers at the University of Basel in Switzerland exploited this critical phase, known as an epithelial-mesenchymal transition (EMT), to coax breast cancer cells in mice to turn into harmless fat cells. The proof-of-concept study appears Jan. 14, 2019, in the journal Cancer Cell.

Young-onset diabetes linked to higher risk of hospitalization for mental illness before age 40

EurekAlert! - Dom, 01/13/2019 - 23:00
Young-onset diabetes, which is defined as onset before age 40, is associated with a higher risk of being hospitalized for mental illness compared with those who develop diabetes later in life. Those with young-onset diabetes also faced increased hospitalizations for any reason across their lifetime. Findings from a population-based cohort study are published in Annals of Internal Medicine.

American College of Physicians releases new edition of Ethics Manual

EurekAlert! - Dom, 01/13/2019 - 23:00
The American College of Physicians (ACP) today released the seventh edition of its Ethics Manual. New or significantly expanded sections of the ACP Ethics Manual include precision medicine and genetic testing, research and protection of human subjects, telemedicine, electronic communications, social media and online professionalism, electronic health records, and physician volunteerism.

UN warns of rising levels of toxic brine as desalination plants meet growing water needs

EurekAlert! - Dom, 01/13/2019 - 23:00
A fast-rising number of desalination plants (~16,000, with capacity concentrated in the Middle East / North Africa) quench a growing thirst for freshwater but also create a salty dilemma: how to deal with the chemical-laden leftover brine.In a new analysis, UN experts say that for every litre of freshwater, desalination plants produce on average 1.5 litres of brine (though values vary dramatically by plant). Globally, 142 million cubic meters of brine is discharged daily.
