Thursday Threads: Disruption in Library Acquisitions, Publishing, and Remedial Education plus Checking Assumptions of Cloud Computing and a National Digital Library

by Peter Murray in Disruptive Library Technology Jester

If it is Thursday it must mean it is time for another in this series of Thursday Threads posts. This week there are an abundance of things that could fall into the category of “disruptive innovation” in libraries and higher education. If you find these interesting, you might want to subscribe to my FriendFeed stream [...]Post from: Disruptive Library Technology JesterThursday Threads: Disruption in Library Acquisitions, Publishing, and Remedial Education plus Checking Assumptions of ........

Climate Change & Human Population

by Michael Windelspecht in RicochetScience

A Night View of Planet Earth (Image Courtesy of NASA )

What will it take to curb carbon dioxide emissions? Over 90% of the light being emitted in the picture above was generated using fossil fuels. The facts are that, on average, each person on the planet requires 1,819 kg of oil per year.   So there are two choices - reduce the carbon footprint of each person, or reduce the total number of people. Since the world population is not expected to decline, there has been a real effort to........ Read more »

Bacteria using bacteria

by Lab Rat in Lab Rat

There are lots of things I enjoy about studying bacteria. I love their biochemistry and the secret inner workings of their metabolic pathways. I love that everything they do the manage within the confines of a single cell, and I love that you can go in there with a wrench and hit some genes until they make what you want.But what I'm really enjoying exploring at the moment is more ecological bacteriology; how bacteria interact with their environment. How they respond to changes to stresses and, m........ Read more »

Hide and Seek

by Journal Watch Online in Journal Watch Online

Want to rediscover an “extinct” mammal? Start by looking for a critter that researchers believe was done in by habitat loss within the last 100 years. Your odds of bringing it back from the dead aren’t too bad, concludes a provocative new study. It also suggests that conservation biologists stop wasting their time and money […] Read More »...

The link between coffee and acute ischemic stroke onset

by Psychothalamus in Psychothalamus

Do you drink coffee on a regular basis? I do. And what does drinking coffee have to do with acute ischemic stroke? In a study published in Neurology, Mostofsky and colleagues investigated the relationship between drinking caffeinated coffee and the risk of acute ischemic stroke in the next hour. Using a case-crossover design, each subject served as his/her own control. All the subjects were patients with a confirmed diagnosis of ischemic stroke. Coffee consumption information one hour before the........ Read more »

Brain Tutor HD iPad App Review

by William Yates, M.D. in Brain Posts

I have previously posted a review of the brain imaging applications Brain Tutor and 3D Brain.  My original review of the two applications for the iPhone and iPod Touch is located here and a review of the applications for the iPad are located here.The original iPad review noted that the iPad versions of both applications were essentially the iPhone version with the common 2x modification that essential doubles the size of the image to accommodate the larger screen with the iPad.  There ........

Fitter Kids = Bigger Brains

by agoldstein in WiSci

Parents take note: if you want your kids to grow bigger brains, think twice about letting schools cut recess or skimp on physical education.

Animal and human studies have long shown that exercise increases neurogenesis, especially in memory- and learning-related areas of the brain. More recently, research on human adolescents has not only confirmed these findings, but highlighted the importance of physical activity for children.... Read more »

What they found in the virtual screening jungle

by The Curious Wavefunction in The Curious Wavefunction

If successful, virtual screening (VS) promises to become an efficient way to find new pharmaceutical hits, competitive with high-throughput screening (HTS). Briefly, virtual screening screens libraries of millions of compounds to find new and diverse hits, either based on similarity to a known active or by complementarity to a protein binding site. The former protocol is called ligand-based VS (LBVS) and the latter is called structure-based VS (SBVS). In a typical VS campaign, either LBVS or SBV........ Read more »

SVP Dispatch, Part 3: Raptorex—To Be, or Not to Be?

by Brian Switek in Dinosaur Tracking

One of the biggest dinosaur stories of 2009 was the discovery of a pint-sized tyrant called Raptorex. Described by a team of paleontologists led by Paul Sereno and dated to about 126 million years ago, the dinosaur showed that many definitive tyrannosaur characteristics—such a puny forearms—evolved when the predators were still small. But a story [...]... Read more »

You can never have too many shoebills

by Darren Naish in Tetrapod Zoology

The recent, brief foray into Shoebill territory made now a sensible time to use a few other Shoebill-based images I have here in the Tet Zoo archives. That, and I haven't been able to finish anything more substantive due to other commitments. We begin with a lateral view of a skull I once photographed - sorry about the crazy colours, once again my fantastic photographic skills have done me proud (this image is a scan of a piece of special paper featuring the image...

Repost: Controls are Cool

by Becky in It Takes 30

Many of you know that as a post-doc in Uri Alon’s lab, Galit Lahav caused a small revolution in our understanding of how the p53 network responds to DNA damage.  By looking at single cells instead of populations, she showed that individual cells responding to the damage caused by gamma-irradiation show a series of stereotyped [...]...

BMJ meta-analysis: Reboxetine “an ineffective and potentially harmful antidepressant”

by David J Kroll in Terra Sigillata

Thanks to Ben Goldacre and Vaughan Bell, I learned this morning of an interesting paper in British Medical Journal that analyzed substantial unpublished data from Pfizer on their norephinephrine reuptake inhibitor antidepressant, reboxetine. Sold in Europe as a pair of enantiomers under the trade name Edronax, reboxetine’s US application was rejected by the FDA in [...]... Read more »

Another APPLES Study

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

For what may appear rather unimaginative, obesity researchers seem to like the acronym APPLE(S) for their studies.
Thus, some readers may be aware that there is an ongoing APPLE School project led by the University of Alberta, which looks at school interventions to prevent childhood obesity.
In a paper just published in BMC Health Services Research, we [...]... Read more »

War crimes and the ruin of law

by SAGE Insight in SAGE Insight

From Millennium – Journal of International Studies The Criminal Tribunal for the Former Yugoslavia (ICTY) has acted as a prototype for international criminal justice in the aftermath of violent conflict and stated that ‘those who perpetrate horrific war crimes, genocide, and crimes against humanity will not go unpunished’. It poses the question if such differentiation [...]... Read more »

Influenza A H1N1: current state

by Atila Iamarino in Influenza A (H1N1) Blog – English

A year has passed since the first cases of Influenza A H1N1 in Mexico, we had over 18000 deaths confirmed by lab diagnosis and reported to WHO. Surely an underestimate of the total number of cases.
The average mortality was of 0.5% of the confirmed cases, close to the seasonal flu. The mortality values varied a [...]... Read more »

The self-control meta-game

by Michelle Greene in NeurRealism

Previously, I wrote about the use of neuroscience in the courtroom as a defense for criminal actions. I asserted that these arguments hold water only insofar as they can demonstrate a clear causal connection between the brain injury and the criminal behavior, and that it was not possible for the defendant to control himself in the presence of such a brain injury.Although I am a card-carrying pinko, I am enjoying the new book by Gene Heyman, Addiction: A Disorder of Choice.

The ultimate cause of social disparity in preventative health behavior may be rooted in environmental harm

by Phil Camill in Global Change: Intersection of Nature and Culture

In a fascinating new article in PLOS One (open access), Daniel Nettle asks why we see social gradients in preventative health behaviors:
People of lower socioeconomic position have been found to smoke more, exercise less, have poorer diets, comply less well with therapy, use medical services less, adopt fewer safety measures, ignore health advice more, and [...]... Read more »
