Cleaning up emissions

by sciencebase in Sciencebase Science Blog

Emissions trading is an economic workaround, a fudge if you will, to reducing one’s pollution levels by buying off the emissions credits of others who are polluting less. Emissions trading (also known as cap and trade) is a market-based approach used to control pollution by providing economic incentives for achieving reductions in the emissions of [...]Cleaning up emissions is a post from: Sciencebase Science Blog

Unmasking Eoanthropus dawsoni, The First Englishman

by Krystal D'Costa in Anthropology in Practice

Fellow blogger and Scientope Scicurious played host to the most recent edition of The Giant’s Shoulders, a blog carnival that recognizes folks who use classic science papers in their writing. Sci put together a spectacular collection of posts based on the theme of Fools, Frauds, and Failures, and it’s certainly worth perusing.
I had high hopes for participating in this round of the carnival, but

Does caffeine help you drink?

by TwoYaks in Gene Flow

It was my brother who told me that drinking coffee while drinking alcohol was a good idea - it would lessen the effects of intoxication. I launched into an ethanol fuelled discussion of how physiologically implausible that sounded to me, but we were celebrating a great occasion, and so I don't think I got much beyond slurring something about cyclic AMP before we instead had some of Arizona's ...

Where did the oil go?

by Sarah Stephen in An ecological oratorio

The recent oil spill in the Gulf of Mexico released, as we have all seen on tv, a lot of oil. Quite how much is a "lot" is a bit of a guess, but roughly 4.9 million barrels, or 784 million litres*. What actually happened to this oil was reviewed recently in an article in Science (Kerr 2010). Only about 0.1% was recovered from beaches and marshes (that´s still an awful lot of oil!). About 17% was siphoned away at the well head, 5% burned off at the surface, and only 3% skimmed off........ Read more »

Bicycles are Good For You--Really

Public health law research is necessary, even if so much is proving the obvious, but once you get the numbers, you can hopefully get policy changes. But now it can be told: your bicycle is good for your health, despite its dangers.... Read more »

Heroic Fungi

by Journal Watch Online in Journal Watch Online

Talk about your historic biodiversity. A polar hut built by famed Antarctic explorer Ernest Shackleton turns out to house an extraordinary array of fungi. The discovery could help conservators preserve the landmark structure, and offers new insights into life on a continent once viewed as barren.
Shackleton and his 15-member British Antarctic Expedition erected the […] Read More »... Read more »

Scientist Urges "Four Culture" Partnerships on Climate Change Communication

by Matthew C. Nisbet in Age of Engagement

More than 50 years after the publication of CP Snow's seminal Two Cultures, interdisciplinary partnerships between science and other academic "cultures" are being urged once again. Today, urgency is not focused on the Cold War but rather the challenge of engaging society on climate change and other environmental problems.
In an open access article published this month at the journal Frontiers in Ecology and the Environment, I joined with several colleagues to describe the potential for partnersh........ Read more »

Another pointless "acupuncture" study misinterpreted

by Orac in Respectful Insolence

At the risk of once again irritating long time readers who've hear me say this before, I can't resist pointing out that, of all the various forms of "alternative medicine" other than herbal medicines (many of which are drugs, just adulterated, impure drugs), acupuncture was the one treatment that, or so I thought, might actually have a real therapeutic effect. Don't get me wrong; I never bought magical mystical mumbo-jumbo about "meridians" and "unblocking the flow of qi" (that magical mystical ........ Read more »

Jumping Spiders Prefer Vegetated Corridors

by Kevin Zelnio in The Online Laboratory of Kevin Zelnio

Barriers to dispersal come in all shapes and sizes and not all are obvious. Baker conducted experiments with jumping spiders, Phidippus princeps (Salticidae) in which he manipulated corridors connecting patches of old growth fields (clover and alfalfa). Patches were either not connected (bare corridors), all connected, or partly connected by vegetated corridors (see schema [...]... Read more »

Misinformed Consent? What not to tell a patient with back pain

by Lorimer Moseley in BodyInMind

We just came across a fancy patient information form that was given to a patient after an assessment by a clinician. The form just blew our minds (but not in a good way) because it seemed to be the perfect clinical tool for generating ongoing pain and disability, and all by the simple process of [...]...

Should Obesity Prevention Efforts Focus Less On Individuals?

by Arya M. Sharma in Dr. Sharma's Obesity Notes

Obesity is now increasingly recognised as the “natural” consequence of societal changes that have occurred over the past decades to foster an increasingly obesogenic environment.
Yet, rather than focus on the root causes of these societal drivers of obesity, governments apparently prefer to make obesity prevention a personal matter, with a strong emphasis on trying to [...]... Read more »

Ageing per se increases susceptibility to lipid induced insulin resistance in rats

by Colby in

Why is a spider like a Derringer?

by Zen Faulkes in NeuroDojo

The Derringer pistol:

Pros: Easy concealment. Stylish.

Con: You’ve only got one shot.

Argiope bruennichi of the male variety are rather like Derringer pistols. Because, you see, their sex organs tend to break during mating.

Yes. Break off.

You almost can’t help but wonder if being eaten by the female – which is the fate for a large percentage of them – isn’t almost a relief to the poor boys at that point.

When you only one shot at genetic glory, you would expect to aim at the ta........ Read more »

A voyage from molecular genetics to microbial ecology -- includes a fish tank and some cartoons

by Cesar Sanchez in Twisted Bacteria

The March issue of International Microbiology included a very nice article by Roberto Kolter, professor of Microbiology and Molecular Genetics at Harvard Medical School. The title is Biofilms in lab and nature: a molecular geneticist’s voyage to microbial ecology (freely available as PDF).In the article, the author gives an entertaining account of the path that lead him to the study of biofilms -- that is, aggregations of microbes growing on solid substrates. He also highlights some of his rec........ Read more »

Evolution of Colour Terms: 3 Perceptual Constraints

by Sean Roberts in A Replicated Typo 2.0

Continuing my series on the Evolution of Colour terms, this post reviews evidence for perceptual constraints on colour terms. For the full dissertation and for references, go here.

The perceptual space that results from the processing of opponent colours is non-uniform (see Figure below), meaning that there are optimal ways to describe it (Jameson & D’Andrade, . . . → Read More: Evolution of Colour Terms: 3 Perceptual Constraints... Read more »

The final (?) word on those handaxes from Crete

by Julien Riel-Salvatore in A Very Remote Period Indeed

While everybody was busy talking about unexpectedly old cutmarks and other Pleistocene goings-on last week, the paper by Strasser et al. (2010) describing the discovery of quartz handaxe assemblages on Crete quietly came out in Hesperia. This is a topic that was discussed at length on this blog, in several posts that generated a large amount of comments a few months back. The sticking point of ... Read more »
