by Christopher Leo in Christopher Leo

Case studies have unjustifiably acquired a reputation for being semi-anecdotal investigations of the small details of individual circumstances, research that is incapable of generating significant empirical or theoretical advances in knowledge. It is argued that the case study is, at best, a preliminary step, in that it may generate hypotheses that can later be tested using such “more reliable” methods as standardized questionnaires or statistical data. In the study of politics, however, tha........ Read more »

US researchers step closer to personalised cancer care

by Cancer Research UK in Cancer Research UK - Science Update

US scientists today report that they’ve identified ‘personalised’ genetic markers in the blood of two bowel cancer patients using a cutting-edge technique called massively parallel DNA sequencing, and used these markers to monitor the patients’ cancers during treatment.
The team say that their new technique – dubbed PARE (‘personalised analysis of recombined ends’) – is a [...]... Read more »

30g of protein per meal for optimal muscle building? That Depends - a lot

by mc in begin to dig (b2d)

Less and More? Yes, when talking protein. Have you encountered any of these questions? How much protein can i eat at a sitting? What's the right amount of protein to eat? How much protein can i absorb? These are questions in the fitness world that get asked all the time - especially by folks who want to optimize their muscle growth. The answer seems to be "less than you think, but more often"... Read more »

Multicellular bacteria

by Lab Rat in Lab Rat

Part of my NatSci course at the moment involves group supervisions, which are made up of around ten people; a mix of students and faculty (all from the Biochemistry department). About halfway through last term we had a supervision about nuclei, and one of the supervisors raised the question, "Is it possible to be multicellular without a nucleus?" (by nucleus he meant chromosomes wrapped up in a membrane, rather than the bacterial arrangement of coiled up DNA loosly attached to the outer cell mem........ Read more »

Of men and me

by James Lloyd in The Y.O.R.F.

I recently had a look through some new papers published on moss (Physcomitrella patens) and found one published in Cell titled ‘Transcriptional control of gene expression by microRNAs’ [1]. This didn’t seem to fit the same pattern of a lot of moss papers I have read (ie in less high impact journals). This paper shows how useful moss is for studying gene expression using reverse genetics (so hopefully my PhD wont be a failure). I think it is important to study important biological problems,........ Read more »

Neury Thursday: Ependymal Cells Regulation of Ventricular Function

by Allison in Dormivigilia

Researchers have identified the functional significance of developing ependymal cells that line the ventricular system. Disruption of the ciliary beating of these cells perturbs the circulation of cerebral spinal fluid within the ventricles and may lead to fluid retention in the head,which is typically fatal....

Cancer risks of cooking on a gas hob overplayed

by Cancer Research UK in Cancer Research UK - Science Update

Don’t panic. Despite this morning’s headlines suggesting that cooking on a gas stove could lead to cancer, it’s not exactly time to abandon your pots and pans or to trade the gas oven in for an electric one.
As we’ll discuss below, this shouldn’t be a problem for anyone with decent ventilation in their kitchen. And [...]... Read more »

Prophage Masquerade

by Merry Youle in Small Things Considered

Roseovarius nubinhibens recently joined the exclusive club of about a thousand bacteria whose genomes have been sequenced. Why this honor? It’s a member of one of the most ubiquitous and most intensely studied clades of α-Proteobacteria, the marine roseobacters. This populous group participates in important jobs, including the global cycling of sulfur, climate regulation, and even modulation...... Read more »

Intrinsic motivation and exercise adherence

by PhD Blogger in Exercise Psychology

This journal article is a little old. Its from 1997, however as its on adherence and recruits from university student, my present research recruits from university staff, its well worth a read. Ryan et al., examined adherence to exercise classes at an aerobics and a Tae Kwon Do class. They reported that the Tae Kwon Do participants both reported greater enjoyment of the class and had a higher adherence than the aerobics participants. The authors postulated that the aerobics participants would be........ Read more »

Your eyes betray the timing of your decisions

by Mo in Neurophilosophy

WHEN it comes to making decisions, timing can be everything, but it is often beneficial to conceal the decision that has been made. Take a game of poker, for instance: during each round, the player has to decide whether to bet, raise the stakes, or fold, based on the hand they have been dealt. A good player will have perfected his "poker face", the blank expression which conceals the emotions he feels and the decisions he makes from the other players sitting at the table.

Increasing numbers of ........ Read more »

Growth Needs Sadness

by Cole Bitting in Fable

It appears that few people consciously intend to make meaning out of trauma or to benefit from it. Posttraumatic Growth is most likely a consequence of attempts at psychological survival.

Tedeschi and Calhoun, Posttraumatic Growth 1

After a traumatic event, what then? The trauma itself causes significant psychological distress and need for psychological adjustment to alleviate the distress. Without adjustment, the posttraumatic distress persists (and if pathological is PTSD).

Trauma i........ Read more »

Iron in the Beaks of Birds

by John Beetham in A DC Birding Blog

Birders know well that birds migrate – the cycle of bird movements keeps birding interesting throughout the year. Many landbird migration routes are well-documented, and even some over-water routes are starting to be determined. What is less understood is how the birds know where they are going. Recent research has focused on how birds might sense, or even see, the Earth's magnetic field for orientation. At least one recent study proposed that some birds use an olfactory sense for guidance.

MPAs reduce coral cover loss. Now we need more of them.

by Uncharted Atolls in Uncharted Atolls

Marine protected areas (MPAs) can be an effective means to conserve coral reef communities.  These areas can provide refuges for larvae, help restore healthy food webs, and help mitigate overgrowth via macroalgae by preventing the overexploitation of grazers in coral reef ecosystems.  This last point is an especially important one…for example, in the aftermath of [...]...

Snakes interrupted: roads causing genetic decline

by Rob Goldstein in Conservation Maven

For wildlife like the timber rattlesnsake, trying to cross even light-traffic country roads presents a formidable life-or-death challenge. As a new study in the journal Conservation Biology shows, these roads can also contribute to the genetic decline of the species.... Read more »

Journal Club – In Vivo Inhibition Dynamics

by AndrewHires in Brain Windows

Inhibition has a powerful role shaping the network dynamics of the cortex, but most studies of inhibitory circuitry are done in brain slice or anesthetized animals. In Membrane potential dynamics of GABAergic neurons in barrel cortex of behaving mice, Gentet et al use two-photon imaging to guide dual, whole-cell patch clamp of inhibitory and excitatory neurons in the mouse barrel cortex. ...

Chromatic aberration of the eye: to correct or not to correct?

by Pablo Artal in Optics confidential

The human eye suffers of a very large chromatic aberration. This means that when a red object is in focus, a blue one at the same distance will be clearly out of focus. Why we are not yet routinely correcting this defect to improve vision? You will find here some new experiments, results and explanations...... Read more »

Seawalls may affect abundance of prey for shorebirds, salmon

by Rob Goldstein in Conservation Maven

A new study in Puget Sound, Washington, suggests that building seawalls and other shoreline structures may reduce the diversity and abundance of some intertidal invertebrates and coastal insects. Because these creatures are food for salmon, shorebirds, and other wildlife, shoreline armoring might indirectly alter the broader ecosystem...... Read more »

achieving transcendence with brain surgery

by Greg Fish in weird things

Want to get closer to your supernatural deity of choice? You could spend years memorizing holy books, scrolls purported to contain ancient wisdom, and study dense, esoteric tomes filled with endless ruminations on all kinds of vague topics, like most religious scholars. Or you could just have surgery on your parietal cortex and give it [...]... Read more »

Inbreeding bad for invasives too

by CJA Bradshaw in ConservationBytes

I just came across this little gem of a paper in Molecular Ecology (not, by any stretch, a common forum for biodiversity conservation-related papers). It’s another one of those wonderful little experimental manipulation studies I love so much (see previous examples here and here).
I’ve written a lot before about the loss of genetic diversity as [...]... Read more »
