Microbial competition and evolution in natural porous environments: Not that simple [Letters (Online Only)]

PNAS Early Edition Articles - Fri, 03/24/2017 - 19:15
In their recent article, Coyte et al. (1) use an innovative combination of microfluidic experiments, mechanistic models, and game theory to study the impact of physical microenvironments on the activity of bacteria in porous media. The authors find that hydrodynamics can profoundly affect how bacteria compete and evolve in these...

Reply to Baveye and Darnault: Useful models are simple and extendable [Letters (Online Only)]

PNAS Early Edition Articles - Fri, 03/24/2017 - 14:22
Model building is the art of selecting those aspects of a process that are relevant to the question being asked. John H. Holland (1) Baveye and Darnault (2) contend that our model (3) is too simple and that we should have considered more intricate biofilm distributions and other microbes than...

Partner abundance controls mutualism stability and the pace of morphological change over geologic time [Evolution]

PNAS Early Edition Articles - Fri, 03/24/2017 - 12:57
Mutualisms that involve symbioses among specialized partners may be more stable than mutualisms among generalists, and theoretical models predict that in many mutualisms, partners exert reciprocal stabilizing selection on traits directly involved in the interaction. A corollary is that mutualism breakdown should increase morphological rates of evolution. We here use...

Epigenetic contribution to diversification [Commentaries]

PNAS Early Edition Articles - Fri, 03/24/2017 - 12:57
Sexual propagation usually occurs between genetically similar partners belonging to a species, a subspecies, or a population. Breeding outside of these groups generates hybrids, progeny of parents with substantial genetic differences. In some cases, hybrids are more vigorous than each parent, a phenomenon called heterosis (1), which explains the success...

Rapid evolution of resistance to parasitism in biological control [Commentaries]

PNAS Early Edition Articles - Fri, 03/24/2017 - 12:57
A growing awareness of human dependence on the natural capital of ecosystem services has highlighted the importance of such services to the sustainable management of both natural and production ecosystems. Biological control is an ecosystem service in which a pest, pathogen, or weed is effectively controlled through an ecological interaction...

Magnetization dynamics and its scattering mechanism in thin CoFeB films with interfacial anisotropy [Applied Physical Sciences]

PNAS Early Edition Articles - Fri, 03/24/2017 - 12:57
Studies of magnetization dynamics have incessantly facilitated the discovery of fundamentally novel physical phenomena, making steady headway in the development of magnetic and spintronics devices. The dynamics can be induced and detected electrically, offering new functionalities in advanced electronics at the nanoscale. However, its scattering mechanism is still disputed. Understanding...

Cheers! Last Year, America’s Major TV Networks Spent Just 50 Minutes On Climate Change. That’s It.

Climate Depot - Fri, 03/24/2017 - 12:55
Major TV networks spent just 50 minutes on climate change — combined — last year. That’s a dramatic, 66-percent drop in coverage from 2015 across evening and Sunday news programs airing on ABC, CBS, NBC, and Fox, according to a new study from Media Matters.

STUDY: Current Global Warming Is ‘Not Outside The Range Of Natural Variations’

Climate Depot - Fri, 03/24/2017 - 11:37
By MICHAEL BASTASCH A UK-based climate policy group has put out an annual climate assessment “exclusively on observations rather than climate models” to serve as a counterpoint to those put out by the United Nations and government agencies that warn of unabated global warming. The Global Warming Policy Foundation’s (GWPF) climate assessment, like the World Meteorological [...]

Trump Ally Calls For US To Roll Back Obama’s Climate Commitment

Climate Depot - Fri, 03/24/2017 - 11:30
A close ally to President Trump in the House is urging him to reduce the United States’ international pledge to cut greenhouse gas emissions to fight climate change. Rep. Kevin Cramer (R-N.D.), who was an energy adviser and public ally for Trump’s campaign, made arguments for a revised commitment in a letter outlining three conditions [...]

Warmist Joe Romm laments: ‘Media’s climate coverage collapsed in 2016 — just when we needed it most’

Climate Depot - Fri, 03/24/2017 - 11:29
Trump’s budget targets federal funding of PBS, the one network with the most climate coverage. In 2016, the major networks’ coverage of climate change dropped by two thirds compared to 2015. In fact, climate coverage last year was close to its lowest levels since 2009, according to a new analysis by MediaMatters of the evening [...]
