Algae living within the soft tissue of coral supply much of the energy needed by their hosts, and some symbiotic algae help coral withstand warmer water better than others. In a recently published study led by the University of Hawai‘i at Mānoa, researchers found that there was a tradeoff for corals dominated by the thermally sensitive algae—they have higher growth, but only in cooler water.  “As the ocean continues to warm, understanding how symbionts and environmental factors affect coral growth and health will help predict reef futures and inform conservation interventions where coral stocks are selected ...

Some patients with myelodysplastic syndromes, like acute myeloid leukemia, benefit from a chemotherapy drug called decitabine that stunts cancer growth. But many others are resistant to decatibine’s effects or become resistant over time. Wilmot Cancer Institute researchers have uncovered a “genomic tug of war” in animal studies that could influence how well certain patients—or certain cancers—respond to decitabine. In a study published in the journal Development, ...

The question of disembodied consciousness or the afterlife has received much scientific scrutiny over the last several years. One line of research involves so-called "channelers" or mediums who claim to receive and communicate information that they believe comes from some other being or dimension of reality that differs from everyday reality. Now, an international team of scientists has critically examined these claims. New research published in the Journal of Scientific Exploration asked 15 pre-vetted channelers to access the same "nonphysical being or spirit" source and answer a structured set of 10 questions from the scientific team. The statistical ...

Over the last four decades, insulin manufacturers have extended their periods of market exclusivity on brand-name insulin products by employing several strategies, including filing additional patents on their products after FDA approval and obtaining many patents on delivery devices for their insulin products. That is the conclusion of a new analysis of FDA and patent records carried out by William Feldman of Brigham and Women’s Hospital, USA, and colleagues, and published November 16th in the open access journal PLOS Medicine. Insulin is the primary, life-saving treatment for type 1 and some type 2 diabetes but remains costly in the US even ...

Socioeconomic differences in healthcare utilization have persisted in modern welfare states even with universal healthcare. In recent decades, Sweden has witnessed a rise in income inequalities, accompanied by shifts in the sociodemographic composition of the population ...

A new study published this week in Science challenges the notion that only humans are capable of forming strong and strategic cooperative relationships and sharing resources across non-family groups. Researchers from Harvard University and the German Primate Center examined the pro-social behavior of bonobos (Pan paniscus), one of humanity’s closest living relatives, finding that their cooperation extends beyond one’s own group to societal cooperation with different groups. Studying humans' two closest living relatives, chimpanzees and bonobos, can help reconstruct ancestral human traits like cooperation and conflict. Despite living in similar ...
