Labelling alerts consumers to qualities of the food that are not apparent from its intrinsic appearance.  these qualities are referred to variously as imperceptible, intrinsic or unobservable--and may include statuses such as 'organic' or 'genetically modified'. Concern about these qualities is termed "ethical preference". In the absence of labelling or other information that informs ethical choices, consumer are likely to feel less trust in the product. (Michalopoulos et al, 2008).Understa........ Read more »

Eocene Florida Plant Remains = Rethink Local Geology A Little

by Greg Laden in Greg Laden's Blog

Sometimes interesting scientific evidence shows up in unexpected places. Years ago, there had been discussion of the possibility that immediate post glacial climate in the North Atlantic coastal region was unusually warm, but the evidence was spotty. Then, I was looking through material taken from a geotechnical boring placed to assess the geology of a part of Boston Harbor where a new tunnel was being planned, and found a large fragment of a clam embedded in clay. The clay was deposited duri........ Read more »

Bushbuck: two species where there was one

by davesbrain in Dave Hubble's ecology spot

Back in the day, the bushbuck was considered a single species, Tragelaphus scriptus, found in various habitats across much of sub-Saharan Africa. Recently however, genetic studies have indicated that T. scriptus is actually a complex of two distinct species, the Kéwel (T. scriptus) and the Imbabala (T. sylvaticus). This evidence shows that these two bushbuck species are more closely related to other tragelaphines than to each other; the Imbabala being closest to the Bongo (T. eurycerus) and Sit........

Using Fear to Flirt: The “Scary Movie Effect”

by Rob Mitchum in ScienceLife

The Friday the 13th and Nightmare on Elm Street movies aren’t typically thought of as mating strategies. But putting on a scary movie is a trick as old as drive-in theaters for encouraging one’s date to jump in fright and snuggle in just a little bit closer. Birds, so far as we know, aren’t into [...]... Read more »

Physics of the Riemann Hypothesis

by Marco Frasca in The Gauge Connection

In this blog I discuss frequently about one of the Clay Institute’s Millenium Prize problems: Mass gap and existence of a quantum Yang-Mills theory. Sometime I also used the Perelman’s theorem containing Poincarè’s conjecture to discuss about some properties of quanum gravity and also Cramer-Rao statistical bound. Today on arxiv I have found a beautiful [...]... Read more »

Evolution's Rainbow, from sparrows' stripes to lizard lesbianism

by Jeremy Yoder in Denim and Tweed

Evolutionary biology is not just the study of how living things change over time, but the study of how the diversity of living things changes over time. Diversity is the raw material sculpted by natural selection, carved into more-or-less discrete chunks by speciation, and lost forever in extinction.

Joan Roughgarden is even more preoccupied with diversity than most evolutionary biologists. Some of her earliest published studies examine the evolution of optimum niche width, the range of resourc........ Read more »

The genetics and phenotypes of the Jamaican click beetle (Adaptive Recursion II)

by Kele in Kele's Science Blog

In my last post I started a new short series on some biologists’ attempts to solve what they call an “adaptive recursion” or in other words, to know the full story of a trait from the bottom level of the gene to the top levels of ecology and differential fitness. Ecological descriptions frequently become “just-so [...]... Read more »

Evolving Linguistic Replicators: Major Transitions and Grammaticalisation

by Wintz in A Replicated Typo 2.0

Just before Christmas I found myself in the pub speaking to Sean about his work on bilingualism, major transitions and the contrast between language change and the cultural evolution of language. Now, other than revealing that our social time is spent discussing our university work, the conversation brought up a distinction not often made: whilst language change is part of language evolution, the latter is also what we consider to be a major transition. As you evolutionary biologists will know, ........ Read more »

Fact or fallacy, a survey of immunisation statements in the print media

Most of us know anecdotally that print media on occasion present immunisation information incorrectly, but you can’t put a finger on how often and when without hard numbers.

Not so wild thing

Different branches of biological research often use different model organisms.

Another model organism is the nematode C. elegans. These tiny worms that live in rotting fruit are [...]... Read more »

Duplicate to innovate?

by Becky in It Takes 30

The question of how new protein functions arise in evolution via duplication has a certain “chicken and egg” flavor to it.  It’s clear that genes with new functions do often arise after older genes undergo a duplication event, but which comes first, the new function or the duplication?  For a long time it seemed obvious [...]...

The bumbebee tit

by Africa Gomez in BugBlog

Today I watched a pair of Blue Tits paying a lot of attention to the inflorescences of Mahonia in the local park, coming back to them again and again. What were they doing? If you hear nectar feeding in birds you would most likely think on hummingbirds and the tropics. However, several bird groups feed on nectar in addition to hummingbirds, honeyeaters and sunbirds. In Australia, they are actually the main flower pollinators. Although nectar feeding behaviour is far less widespread, it does happ........ Read more »
