When coral species vanish, their absence can imperil surviving corals ScienceDaily: Latest Science News urn:uuid:87001bc1-8008-ad8e-d604-a6b2101da70d Wed, 23 Jan 2019 14:35:19 -0600 As coral species die off, they may be leaving a death spiral in their wake: Their absence could be sapping life from the corals that survive. In a new study, when isolated from other species, corals got weak, died off or grew in fragile structures. The study has shown it is possible to quantify positive effects of coral biodiversity and negative effects of its absence.

Small metabolites have big effects on the intestinal immune response ScienceDaily: Latest Science News urn:uuid:b43433c3-22e6-7ab0-97cf-08b9f955aea4 Wed, 23 Jan 2019 12:17:03 -0600 Normal gut bacteria are instrumental in inducing an immune response in the presence of invading pathogens. However, exactly how commensal bacteria cause CX3CR1+ macrophages in the intestine to protrude their tentacle-like dendrites to capture antigens, triggering the immune response, was unclear. Now, a research team has shown that common bacterial metabolites pyruvate and lactate interact with the GPR31 receptor on CX3CR1+ cells, enhancing the immune response and protecting against gut pathogens. Climate change tipping point could be coming sooner than we think ScienceDaily: Latest Science News urn:uuid:a074c582-dd50-9151-0f9f-3e5fedd973d3 Wed, 23 Jan 2019 12:17:00 -0600 A new study confirms the urgency to tackle climate change. While it's known that extreme weather events can affect the year-to-year variability in carbon uptake, and some researchers have suggested that there may be longer-term effects, this study is the first to actually quantify the effects through the 21st century and demonstrates that wetter-than-normal years do not compensate for losses in carbon uptake during dryer-than-normal years, caused by events such as droughts or heatwaves.
