Citing versioned papers, robots and reviewers?

by Daniel Mietchen in Research Cycle Research

Established scholarly citation practices are tailored towards static documents. With the use of versioned documents spreading, citation formats have to follow suit. This requires to balance the need for proper identification of the source of a claim with the demands for cited information being up to date. Getting this right is particularly important in naturally versioned environments like wikis or GitHub. Continue reading →... Read more »

The Allure of Gay Cavemen

by Eric Michael Johnson in The Primate Diaries

The latest stop in the #PDEx tour is being hosted by Neuron Culture at Wired:In 1993 the reputable German weekly Der Spiegel reported a rumor that Otzi, the 5,300-year-old frozen mummy discovered in the Otztal Alps two years earlier, contained evidence of the world's earliest known homosexual act. "In Otzi's Hintern," wrote the editors, referring to the Iceman's hinterland, "Spermien gefunden worden." (If you require a translation, chances are you didn't want to know anyway.) The rumor quickly s........ Read more »

Great, now I’m yawning too.

by helikonios in The view from Helicon

From the annals of adorable research: You know how yawning is contagious? That’s not just a human thing. Chimpanzees, several other primates, and possibly dogs can “catch” yawns from others of their own species. This strange effect might be a byproduct of empathy—not the complex empathy that involves understanding and sharing someone else’s suffering, but [...]... Read more »

BIG Physics for small Science

by Paige Brown in From The Lab Bench

Metallic particles can be synthesized which are adequately small to be suspended in a liquid phase, where the particles exist on a size scale such that buoyancy in the medium and forces of gravity are balanced, and the particle solution, known as a colloid, is stable. In this state, these nanoparticles, named after their dimensions on the nanometer scale (1/billionth of a meter), will stay dispersed instead of precipitating out of solution. It might help to think of the similar way in which larg........ Read more »

ENCODE Chromatin state data offers nice insights. Take this and run with it.

by Mary in OpenHelix

mmmmm….another “big data” paper illustrates a point I’ve been hammering on: there is terrific data coming out of these projects–but it’s not in the publications. So I’m going to talk about this paper in this post (1), but I’ll direct you to the database where the information is really available for your perusal–and to a tutorial that explains how to access it. Off we go….

Hypsugines: an assemblage of 'pipistrelle-like non-pipistrelles' (vesper bats part XV)

by Darren Naish in Tetrapod Zoology





As we've seen throughout this series (see links below for previous parts), recent phylogenetic studies have found a number of 'pipistrelle-like non-pipistrelles' to form a novel clade previously unsuspected from morphological studies [composite above shows - l to r - Hypsugo cf. joffrei (from Kruskop & Shchinov (2010)), Neoromicia capensis (from Fernloof Nature Reserve), and Laephotis botswanae]. Following Roehrs et al. (2010), I'll refer to this as the 'hypsugine group'. Hypsugines occur ac........ Read more »

that’s not what we meant by computer scientist

by Greg Fish in weird things

A while ago, there was some buzz on the pop sci circuit about scientists using machines to catch up with the constantly growing body of published papers and asking whether the machines could ever qualify as actual scientists proposing hypotheses of their own. Now there seems to be an affirmative answer since a robot- aided [...]... Read more »

Hormonal therapy and cancer – the controversy rages on

Hormone replacement therapy (HRT) is one of those subjects where many have a strong opinion either way and I suspect even if we have another dozen trials evaluating at the pros and cons, those opinions won’t change very much. That … Continue reading →

Natural selection and saving

by Jason Collins in Evolving Economics

In the academic literature at the intersection of economics and evolutionary biology, evolution of time preference (patience) is one area that has received much attention. This makes some sense, as most economic models that consider decisions over time include time preference. Time preference is normally included in the model through a discount rate of a [...]...

A role for chromatin modifications and DNA repair in renal cell carcinoma

A rig by any other name, could it be an artificial reef?

by Southern Fried Scientist in Southern Fried Science

There are currently more than 7,500 offshore oil platforms actively probing the earth’s crust for black gold. Their relatively minimal appearance at the surface belies the shear magnitude of human construction beneath the waves. Oil platforms are among the world’s tallest man-made structures. Compliant tower platforms reach up to 900 meters in depth (in contrast, [...]... Read more »

One Foot in Front of the Other

by Rob Mitchum in ScienceLife

There are few biological functions that we take for granted more than gait, the intricate symphony of motion that happens almost automatically when we walk or run. Gait is programmed deep into the nervous system of animals, an activity so robust that it is maintained even when large segments of brain are removed. Those crude, [...]... Read more »

Mitochondria and Hypertension

by Jon Wilkins in Lost in Transcription

So, here's a new thing.
Best URL for sharing: http://www.darwineatscake.com/?id=18
URL for hotlinking or embedding: http://www.darwineatscake.com/img/comic/18.jpg

This is based on a recent paper (citation below) where they identify a point mutation in the mitochondrial DNA that appears to result in hypertension.

So why is this interesting? Well, for me, as an evolutionary theorist who works on intragenomic conflict, it is interesting because the mitochondrial DNA is, in principle, subject to s........ Read more »

Birds Inherited Strong Sense of Smell From Dinosaurs

by Brian Switek in Dinosaur Tracking

http://www.youtube.com/watch?v=22Qup626DTc Feathers, air sacs, nesting behavior—the earliest birds owed a lot to their dinosaurian ancestors. The first birds also inherited a strong sense of smell. Modern birds have not been thought of as excellent scent-detectors, save for some super-smellers such as turkey vultures, which detect the scent of rotting carcasses. We typically think of avians [...]... Read more »

Tales from the Intestinal Crypt

by Sanford- Burnham in Beaker

Doctors have noticed for decades that people with Down Syndrome seldom develop cancers. Down Syndrome results from an extra copy of chromosome 21, leading scientists to wonder if something about that particular piece of the genome could protect against cancer. A few years ago, researchers at Johns Hopkins University tested that hypothesis. They added several [...]... Read more »

Eptesicini: the serotines and their relatives (vesper bats part XIV)

by Darren Naish in Tetrapod Zoology





A group of mostly mid-sized pipistrelle-like bats of Africa and the northern continents are known as the serotines (Eptesicus) [species shown here is the one generally known simply as the Serotine E. serotinus: photo by Mnolf, from wikipedia]. Here in Europe this is - along with pipistrelles, noctules and long-eared bats - one of the most familiar of vesper bat groups. As we'll see, this group is anything but boring: it includes some weird big-eared species as well as the only bats known to ........ Read more »

Biology of indolent B-cell lymphomas and chronic lymphocytic leukemia
