Deficit thinking is the belief by elites that the public is simply unaware of or unable to understand science and that lack of knowledge prevents the right policy decision. It rarely works as a strategy.

Scholars at Umeå University in Sweden analyzed public opposition to dam removal,  an increasingly common practice as old splash dams and small hydropower dams have become obsolete, and found that disagreements are not based on knowledge deficiency but are instead a case of different understandings and valuation of the environment and the functions it provides. 

Solar geo-engineering is one proposed approach to mitigating the effects of climate change - the idea being to deflect some of the sun's incoming radiation. 

Ignoring the technology issues, in a world where countries can't even agree they contribute to greenhouse gases, the political uncertainties and geopolitical questions about who would be in charge of solar geo-engineering activity and its goals are daunting. A UN of climate change is the worst of all possible worlds. 

Researchers have described a new technique that might one day reveal in higher detail than ever before the composition and characteristics of the deep Earth. There's just one catch: it can't exist.

Instead of being part of the natural world we know, where we have gravity, the weak and strong nuclear forces and electromagnetism  the new technique would require a fifth, hypothetical force of nature - a long-range spin-spin interaction.   The building blocks of atoms —electrons, protons, and neutrons — separated over vast distances could still "feel" each other's presence.  

Living against our biological clock, working late-night shifts or eating at inappropriate times, can has been linked to health risks like metabolic syndrome, obesity, and diabetes in Current Biology - at least for mice. 

Insulin action rises and falls according to a 24-hour, circadian rhythm, the researchers write. Mice unable to keep the biological time for one reason or another get stuck in an insulin-resistant and obesity-prone mode. 

Researchers have successfully modeled using both familial and sporadic patient-derived induced pluripotent stem cells (iPSCs), and revealed stress phenotypes and differential drug responsiveness associated with intracellular amyloid beta oligomers in
Alzheimer's disease
neurons and astrocytes. 

The health benefits of low-dose aspirin and omega-3 fatty acids in foods like flax seeds and salmon are touted frequently but the detailed mechanisms involved in their effects are not fully known.

A report in Chemistry&Biology says that aspirin helps trigger the production of resolvins, molecules that are naturally made by the body from omega-3 fatty acids. These resolvins shut off, "resolve," the inflammation that underlies destructive conditions such as inflammatory lung disease, heart disease, and arthritis.
