Don't Advocate from a Position of Hate

by Persuasion Strategies in Persuasive Litigator

By: Dr. Ken Broda-Bahm - On some days, just watching the news can stop us cold. Those who work in law should be proud to be part of a system that, however imperfectly, resolves disputes with appeals to reason and judgment rather than force. But the opposite end of the spectrum was seen in last week's devestating shooting in Tucson that left six dead and fourteen injured. While the motives of the shooter remain hazy at the time of writing, one element seems clear: for whatever twisted reason, the........ Read more »

P is happy and N is sad – a biological universal?

by Maria Wolters in Speech and Science

Twitter has been abuzz recently with news of a paper that claims to have found universal sound correlates of happiness and sadness: Auracher, J., Albers, S., Zhai, Y., Gareeva, G., & Stavniychuk, T.

CFTR aids Listeria escape into cell cytosol

by geekheartsscience in geek!

The intracellular pathogen Listeria monocytogenes must escape the vacuole formed during entry into the host cell to replicate in its preferred environment—the cell cytosol—and continues its life cycle. Although the pore-forming bacterial toxin listeriolysin O is vital for Listeria escape … Continue reading →... Read more »

Targeting dormant bacteria

by Lab Rat in Lab Rat

Antibiotics are effective against bacteria because they target and knock out specific functions that are vital for bacterial survival. As most bacterial infections involve rapid growth and division of the invading bacteria, many commercial antibiotics currently target metabolically active cells, by blocking enzymes needed for growth, reproduction, or cell wall synthesis. While these will kill acute bacterial infections they are often far less effective against dormant bacteria in longer-term per........ Read more »

What is Science?

by Marco Frasca in The Gauge Connection

Reading this Lubos’ post about a very good site (this one) I entered into the comment area and I have found the following declaration by him: Science is a meritocracy where answers are determined by objective criteria, and for most of the difficult questions, only one or a few people know the right answer and [...]...

A Genlisean Effort: A Tale of Two Trans-Atlantic Dispersal Events in the Carnivorous Plant Genus Genlisea

by Ryan Kitko in Cunabulum

An illustration from 1858 on the closed and open Atlantic Ocean.South America and Africa look like they fit together snuggly, like puzzle pieces. It's so intuitive that children can grasp this notion without the aid of a formal education in geology. As an accepted theory, plate tectonics draws on evidence from several supporting disciplines, including paleontology and biogeography. Paleontology and geology are, of course, the primary fields where evidence for continental drift arises, ........ Read more »

Does mathematical training increase our risk tolerance?

by Jason Collins in Evolving Economics

Humans are inherently risk averse. When offered a coin toss with a reward of $10,000 for heads but a loss of $10,000 for tails, most people would decline. They would likely agree to pay a significant sum to avoid the gamble, despite the expected value of the gamble being zero. When economists describe the preferences [...]... Read more »

IRS Serine Phosphorylation and Insulin Sensitivity?

by Dave Bridges in Dave's Blog

This is part of my last year in science series. Click here for the rationale.Insulin signalling passes through a cascade of signaling proteins starting with the recruitment of the Insulin Receptor Substrate (IRS) to the Insulin Receptor.  Insulin resistance, or impaired insulin signaling is a hallmark of obesity and diabetes.  One of the ways in which was thought to happen was through phosphorylation of Serine 307 on IRS, a phosphorylation event which has been proposed to be inhibitor........

Ketogenic Diets

by ABK in Environment and Health

To my friends whom I love dearly and whom are trying to follow ketogenic diets in order to lose weight:I would advocate moderation in just about everything, except for fun and other adrenaline release-provoking activities. Ketogenic diets have proven helpful to people with uncontrolled epilepsy and may be of benefit to epileptics in general, to victims of stroke and other forms of brain injury and possibly cancer. They come with other effects that may not be worth the discomfort or unintended ri........ Read more »

Of autistic mice and men

by Jon Brock in Cracking the Enigma

Studies looking at potential environmental and genetic causes of autism are pretty much always correlational. They may identify risk factors, but they can only ever show that people exposed to a particular risk factor are more likely to have autism. They don’t show whether it actually causes autism. Eating ice cream is a risk factor for getting sunburnt, but (unless you get your ice cream and your sunscreen mixed up) there’s no sense in which ice cream causes sunburn. Even if we are confiden........ Read more »

Cottonmouth Myths I: Snakes Dropping Into Boats

by David Steen in Living Alongside Wildlife


            Some animals just can’t get a break.  Cottonmouths, Agkistrodon piscivorus, (aka water moccasins) would like nothing more than spend their lives within their local swamp or river, either coiled up under a bunch of vegetation waiting for a hapless frog to paddle by, or perhaps patrolling the water’s edge at night looking for some other tasty morsel.  But, we all ...

Imagine the Possibilities

by Shaheen Lakhan in Brain Blogger

Researchers have discovered a way for people to eat less: imagine eating. Better than any diet pill, workout routine or all-cabbage-all-the-time regimen, simply thinking about eating food will make a person eat less. The work is based on a process called habituation — a phenomenon that decreases the responsiveness to and motivation for obtaining food. [...]... Read more »

Is a Deep throat a Sore throat ?

by DefectiveBrayne in The Defective Brain



 One of the reasons that I blog on Streptococcus pyogenes so often is because it is such a fascinating and adaptable pathogen. It causes so many different diseases. Diseases as different as a sore throat, and necrotizing fasciitis (The flesh eating disease !).  It's even been implicated in tourettes syndrome. This is a hardy and adaptable pathogen, that primarily colonises the throat and the ... Read more »

Methicillin-resistant S. aureus (MRSA) JKD6229, freaking out and deadly

by Vasili Hauryliuk in stringent response

Stringent response, as I wrote here, here, and here, and here, is a central regulator of bacterial physiology, which decides whether to grow happily churning out new proteins without a care or to shut down all of the unnecessary systems, relocate all  resources to amino acid production and put up a fight. So what happens if a mutation hyper-activates it in Staphylococcus aureus? Wonder no more - the pathogen goes berserk!The strain in question is call........ Read more »

Autistic Children In The Media

by Neuroskeptic in Neuroskeptic

Emory University's Jennifer Sarrett offers an interesting although sadly brief analysis of the way in which autism is treated in the mass media: Trapped Children.She examines media depictions of children with autism, first in the 1960s, and then today. In those 40 years, professionals radically changed their minds about autism: in the 60s, a lot of people thought it was caused by emotionally distant refrigerator mothers; nowadays, we think it's a neural wiring disorder caused by deleted genes.Y........

The inevitable rise of Amish machines

by Razib Khan in Gene Expression

About 20 years ago I lived for a year in a rural area where Amish were a common feature of country roads and farmers’ markets. My parents, being Muslims, would sometimes buy chickens from the local Amish and slaughter them according to halal. We had a relationship with a particular family. They were nice people, [...]...
