Analysis of biased language in peer-reviewed scientific literature on genetically modified crops

Social, political, and economic forces may inadvertently influence the stance of scientific literature. Scientists strive for neutral language, but this may be challenging for controversial topics like genetically modified (GM) crops. We classified peer-reviewed journal articles and found that 40% had a positive or negative stance towards GM crops. Proportion of positive and negative stance varied

Plastic dinosaurs : Digging deep into the accelerating carbon lock-in of plastics

The continued expansion of plastics production all over the world entrenches modern societies and life styles deeper in the dependence on fossil resources. This research note develops the main aspects of the carbon lock-in in the plastics industry and how it extends into many aspects of contemporary life. With data collected from trade press and reports, we present insights of the investment trend

Sufficient oxygen for animal respiration 1,400 million years ago

The Mesoproterozoic Eon [1,600-1,000 million years ago (Ma)] is emerging as a key interval in Earth history, with a unique geochemical history that might have influenced the course of biological evolution on Earth. Indeed, although this time interval is rather poorly understood, recent chromium isotope results suggest that atmospheric oxygen levels were <0.1% of present levels, sufficiently low to

Recalcitrant carbon components in glomalin-related soil protein facilitate soil organic carbon preservation in tropical forests

Glomalin-related soil protein (GRSP) is known as an important microbial by-product which is crucial for preserving or accumulating soil organic carbon (SOC). However, the underlying mechanisms are not well understood. In this study, we investigated the chemical structures of GRSP and its relationship with SOC using 13C nuclear magnetic resonance (NMR) in three tropical forests. The three forests,

Adult language learning after minimal exposure to an unknown natural language

Despite the literatures on the role of input in adult second language (L2) acquisition, and on artificial and statistical language learning, surprisingly little is known about how adults break into a new language in the wild. This paper reports on a series of behavioral and neuroimaging studies that examine what linguistic information adults can extract from naturalistic but controlled audio-visua

A decomposition approach to evaluating the progress of the New Green Economy

Various policy instruments and policy reforms are being implemented to encourage Green Growth and Green Economy. However, comprehensive ex-post evaluation policy methods have yet to be developed. The emerging literature shows that there is substantial ambiguity and discrepancy about how to measure the performance of policy instruments driving a Green Economy in general and, in our case, a Green En

Characterization of the IgD binding site of encapsulated Haemophilus influenzae serotype b.

Encapsulated Haemophilus influenzae is a causative agent of invasive disease, such as meningitis and septicemia. Several interactions exist between H. influenzae and the human host. H. influenzae has been reported to bind IgD in a nonimmune manner, but the responsible protein has not yet been identified. To define the binding site on IgD for H. influenzae, full-length IgD and four chimeric IgDs wi
