How Did Primordial Biochemistry Become Established on Earth?

by Michael Long in Phased

The time required for biochemical evolution, regarding very slow reactions in a warm environment, is far less than commonly presumed, and primitive catalytic effects can increase with cooling temperatures. These observations plausibly explain how life may have established itself and evolved on Earth.... Read more »

Probing amyloid, one oligomer at a time

by The Curious Wavefunction in The Curious Wavefunction

One of the more important paradigm shifts in our understanding of the Alzheimer’s disease-causing amyloid protein in the last few years has been the recognition of differences between the well known polymer aggregates of amyloid and their smaller, soluble oligomer counterparts. For a long time it was believed that the fully formed 40-42 amino acid protein aggregate found in autopsies was the causative agent in AD, or at least the most toxic one. This understanding has radically changed in the ........ Read more »

Blood of the Mammoth

by John McKay in Mammoth Tales

Catastrophists love frozen woolly mammoths. It doesn’t matter what their preferred catastrophe is–Atlantis sinking, falling ice moons, the Noachian flood, abrupt changes of the Earth’s axis, or a near miss by a pinballing planet disguised as an ancient Near Eastern god–at some point, they will trot out the frozen mammoths as proof positive of their theory. . . . → Read More: Blood of the Mammoth...

Dynamic origins of PBX1 homeodomain allostery

by Michael Clarkson in Conformational Flux

In the Monod-Wyman-Changeux model for cooperative binding, proteins exist in an equilibrium of low-affinity and high-affinity states in solution, absent any ligand. In this view, although it may appear that the binding of a ligand causes a conformational transition, it actually stabilizes one conformation from a pre-existing equilibrium. In the past several years, advanced NMR techniques have yielded increasing evidence that these structural equilibria exist for a number of proteins, suggesting ........ Read more »

How To Fool A Lie Detector Brain Scan

by Neuroskeptic in Neuroskeptic

Can fMRI scans be used to detect deception?It would be nice, although a little scary, if they could. And there have been several reports of succesful trials under laboratory conditions. However, a new paper in Neuroimage reveals an easy way of tricking the technology: Lying In The Scanner.The authors used a variant of the "guilty knowledge test" which was originally developed for use with EEG. Essentially, you show the subject a series of pictures or other stimui, one of which is somehow special........ Read more »

Placebo effect: now we can see it, but should we believe it?

by Lorimer Moseley in BodyInMind

Placebo effects are a great way to start a conversation, particularly if one is at a Clinical Trials Festival. Rather than being fascinated by the possibilities of the brain’s internal capacities to influence its own outputs, some believe placebo effects are a nuisance and something to either ignored or removed. Well, as you will see [...]... Read more »

HIV in America—where do we go from here?

by PalMD in White Coat Underground

The HIV pandemic in the US has developed a stable appearance over the last few years, and that appearance is notably non-white and non-wealthy.  When the pandemic was discovered nearly thirty years ago, it was—in the US—primarily a disease of gay men.  In Africa, the disease is everyone’s.  Women make up significantly more than half [...]...

Why the obsession with intelligibility in speech processing studies?

by Greg Hickok in Talking Brains

There was a very interesting speech/language session at SfN this year organized by Jonathan Peelle. Talks included presentations Sophie Scott, Jonas Obleser, Sonia Kotz, Matt Davis and others spanning an impressive range of methods and perspectives on auditory language processing. Good stuff and a fun group of people. It felt kind of like a joint lab meeting with lots of discussion. I want to emphasize one of the issues that came up, namely, the brain's response to intelligible speech and wh........ Read more »

Coddle me, please: parallel evolution and fishery management in Atlantic cod

by Hannah Waters in Sleeping with the Fishes

Historically, perhaps due to human interest in maximizing fishing activity, we have assumed that there is a great deal of gene flow in marine populations.  This assumption allowed us to maximize fishing efforts without guilt, since a large, ocean-wide population would allow fish from other parts of the world to refill populations that we had reduced by overfishing.  But you know what they say about assumptions: they make an ASS out of U and ME.  Thus marine biologists have taken an interest ........

Would you eat a brown apple?

by Anastasia Bodnar in Biofortified

Have you ever cut up an apple to take for lunch, or prepared apples for a fresh fruit tray only to have them turn an unappealing shade of brown? You’re not alone. There’s nothing wrong with brown apple slices, but they certainly don’t look nice, which discourages some people from eating as many apples as they should. Apples are a healthy snack and anything that gets people to eat more fruit could be considered Continue reading...... Read more »

Gratitude: Uniquely Human or Shared with Animals?

by Jason Goldman in The Thoughtful Animal



"Two chimps had been shut out of their shelter by mistake during a cold rain storm. They were standing dejeted, water streaming down their shivering bodies, when Professor Köhler chanced to pass." Upon opening the door for the two chimps, Dr. James Leuba recounts, "instead of scampering in without more ado, as many a child would have done, each of them delayed entering the warm shelter long enough to throw its arms around his benefactor in a frenzy of satisfaction."

Animal obesity: canary in the coal mine?

by Travis Saunders, MSc in Obesity Panacea

There are a number of factors, both behavioural and environmental, which are thought to play important roles in the current epidemic of obesity. These range from things like increased soft-drink consumption and decreased physical activity, which are at least nominally under our personal control, to more external factors like viruses, light pollution, and environmental contaminants, over which we have little or no control. How much of a role do these external factors play in the obesity epidemi........ Read more »

The Trouble With Triclosan

An article was released online Monday in Environmental Health Perspectives which surprised me.
