Inducing and Monitoring Amyloid Aggregation in Living Cells

by Michael Long in Phased

Elizabeth Jares-Erijman (Universidad de Buenos Aires,

Argentina) and coworkers have developed a non-perturbing protocol

for inducing and monitoring the formation of amyloid aggregates,

implicated in a number of neurodegenerative conditions,

in living cells.

Ooh aah Cantona! Welcome back Eric…

by Duncan Hull in O'Really?

It is great to see the eminent french football philosopher and scientist Eric Cantona back in his adopted hometown of Manchester. As well as visiting in person during production of the latest Ken Loach film (on the famous Keppel Road, Chorlton) and appearing at the premiere, Eric is currently gracing silver screens in cinemas all [...]...

Maps, directions, and video games: A model for how we perceive them

by Dave Munger in Cognitive Daily

[Originally posted January, 2007]

Nearly all video games that offer a first-person perspective -- where the view on-screen simulates what a real person would see as she navigates through the virtual environment -- also include a virtual map to help in navigation. Even my favorite golf game has one. Such maps can be indispensable, but they also invite a question -- should the map rotate to align with the player's viewing angle, or should they remain at a constant orientation?

Aligning the map ........ Read more »

Beyond good and evil: video game effects depend on context

by Jacob Aron in Just A Theory

Much of the scientific research in to the effects of video games on players’ behaviour concludes that violent games promote aggression. Gamers (including myself) often dismiss these findings, resulting as they nearly always do from poorly designed studies. One infamous experiment used the length of time a person held an air horn down before and [...]... Read more »

The Music of the Brain

by Evil Monkey in Neurotopia

First of all, remember that post I wrote on the serotonin theory of depression, and how it was probably wrong? I was right it is at the very least incomplete. Another one bites the dust. It's sad, as we are so desperate to find SOME theory on which we people who like to study depression can hang our hats. But the serotonin one was not to be. Check out the blog coverage. It is incisive. I don't know that we should be THAT hard on the researchers who invented the idea. After all, it was a........ Read more »

Mollusks: Out of sight, out of mind, out of luck?

by Scott A. in JournOwl

If you haven’t yet heard, the Nature Conservancy recently released a report that documented a staggering decline in oyster reefs.  According to the report, “Globally, 85% of oyster reefs have been lost, making oyster reefs one of the most severely impacted marine ecosystem on the planet (Shellfish Reefs at Risk, Nature Conservancy, 2009).”

But as oysters [...]... Read more »

Common Treatment Ineffective for Autism

by Shaheen Lakhan in Brain Blogger

The growing prevalence of autism worldwide has parents and clinicians searching for effective treatment options. Though not approved by the United States Food and Drug Administration for the treatment of autism, a common class of antidepressants is often prescribed to treat the symptoms of autism in children. The selective serotonin reuptake inhibitors (SSRIs) are among [...]... Read more »

A Review of The BCA's Evidence for Chiropractic

by Martin Robbins in The Lay Scientist

Well over a year after Simon Singh's 'libelous' article on Chiropractic was published; with Singh preparing to launch an appeal against Eady's ruling in the preliminary hearing of the result trial; and with the chiropractic profession under siege from a PR nightmare; the British Chiropractic Association have finally decided to release the evidence that they claim backs up their promotion of Chiropractic treatments.

In doing so, they appear to have been deliberately dishonest in their presentat........ Read more »

Trouble with Sex on the Internet

by David Bradley in Sciencetext

Attempts to design websites suited to men or women are misguided because they rely on social stereotypes, according to a recent study. Rather than focusing on gender, the study’s authors suggest that designers should optimize their sites for different character traits: personal autonomy, selfishness, compassion and for whether a person is a hunter or a [...]Post from: David Bradley's Sciencetext Tips and Tricks

So what exactly are force fields good for?

by The Curious Wavefunction in The Curious Wavefunction

Sue Storm tries hard to use her favorite force field to counter the 1 kcal/mol barrierEvery once in a while there is a study asking what method X (X = docking, free energy calculations, molecular dynamics, force fields etc.) is good for. Such studies can be useful to take stock of a particular paradigm. So the question that Jonathan Goodman and his group ask in this paper is "Are force fields good for reproducing non-bonded interactions, especially hydrogen bonding, pi-stacking and dispersion?".........

Resilience revisited

by Jan Husdal in

How many ways are there for defining vulnerability and criticality, really? Traditionally, risk matrixes have a likelihood/impact approach, but not always. Yesterday, I was examining a criticality/vulnerability matrix. Today, I will take a closer look at a criticality/preparedness matrix with a third susceptibility dimension added to it, as presented in the New Zealand research project [...]... Read more »

The Contested Landscape of Jerusalem

by John Matthew Barlow in The Complex Terrain Laboratory

To call Jerusalem a disputed location would be an under-statement. The Temple Mount in that city might be the most hotly contested piece of real estate on the planet, sacred as it is to the 3 major western religions: Judaism, Christianity, and Islam. Archaeologists believe that there has been a city on the site of Jerusalem since about 2600 BCE, meaning that for nearly 5000 years, various groups of people have fought over the landscape: Judeans, Israelites, Assyrians, Babylonians, Persians, Gre........

Self-refilling bowls: An idea whose time should never come

by Dave Munger in Cognitive Daily

[Originally posted in April 2007]

One "trick" dieters often use is to put their food on a smaller plate. The idea is to fool yourself into thinking you're eating more food than you really are. But doesn't our stomach tell us how full we are?

Actually, it doesn't. Brian Wansink has devoted his career to studying how perception of food intake relates to actual eating behavior. Together with James Painter and Jill North, he's come up with a dramatic demonstration of how wrong our stomachs can be......... Read more »

Carrot Tops Healthy Veg

by David Bradley in SciScoop Science Forum

News from my Newcastle University published today reveals that cooking carrots whole and then chopping them before serving is better for your health than slicing and dicing before you boil.

Apparently, less of the “anticancer” compound falcarinol leaches out of the carrots and into the cooking water if carrots are boiled whole. Of course, the truly [...]... Read more »

Shading Earth won’t stop ocean acidification

Geoengineering is the idea that humans can slow, stop or reverse the effects of climate change by altering the composition of Earth’s atmosphere and biosphere.  While controversial, these methods, including reducing sun exposure by injecting aerosols into the atmosphere or using giant mirrors to reflect the sun’s rays, were identified as a high-priority area for [...]...

Food addiction - fact or fiction

by Travis Saunders, MSc in Obesity Panacea

Photo by Marina KomolovaOne topic that never fails to generate a lively discussion is the relationship between obesity and personal responsibility.  For example, in response to a post on psychological exams for bariatric surgery patients, one anonymous reader commented that: I don't have a gym membership. I'm not even all that active. I live in a bad neighbourhood and i'm floating right around the Canadian poverty line. I'm not obese. When I see a little extra belly buil........ Read more »
