The Search For Genetic Polymorphisms of Human Longevity

by Reason in Fight Aging!

Some people have better genes than other people; such is the luck of the draw. The effects of most genetic differences on human longevity appear to be small in comparison to the effects produced by lifestyle choices, however. You are still the master of your own destiny in that regard. Time wasted in wishing you had a better variant of FOXO3A would be better spent exercising. A great deal of modern life science research is focused on deciphering the operation of our genes and metabolism. Along t........ Read more »

charles darwin and otto hahn’s alien fossils

by Greg Fish in weird things


Just because Darwin wouldn’t discuss the origin of life in his work, doesn’t mean he didn’t have an opinion on the matter. And that opinion is actually pretty close to modern scientific thinking, that living things are products of chemistry rather than something requiring divine intervention. A recent paper cataloguing Darwin’s notes on the subject [...]... Read more »

Baby it hurts: birth practices and postpartum pain

by Amy Romano in Science & Sensibility

Ask a bunch of expectant women what worries them about labor, and chances are many of them will say, “the pain.”  Much is made about pain in labor. Women prepare for it, nurses constantly assess it, anesthesiology departments exist to eliminate it, and so on. But while there are many experiences of labor pain, just [...]... Read more »

The illusion of time: Perceiving the effect before the cause

by Mo in Neurophilosophy

A novel temporal illusion, in which the cause of an event is perceived to occur after the event itself, provides some insight into the brain mechanisms underlying conscious perception. The illusion, described in the journal Current Biology by a team of researchers from France, suggests that the unconscious representation of a visual object is processed for around one tenth of a second before it enters conscious awareness.

Obesity as a Disorder of Neural Function

by Travis Saunders, MSc in Obesity Panacea

One of the most interesting (and most complicated) things about obesity is its very strong neural component. Now of course at its most basic level, body weight comes down to the balance of energy intake versus energy expenditure. Unfortunately, many aspects of this energy balance equation are outside the influence of conscious control. The brain is constantly sensing nutrients like glucose, and hormones like leptin and insulin in order to determine current energy stores, and using this inform........ Read more »

Earthquakes within plates: we don't know when, and we may not know where

by Chris Rowan in Highly Allochthonous



Ed has already given the lowdown on a new study in Nature which might lead to a rethink on earthquake hazards in the continental interior. Plate tectonics treats plates as entirely rigid entities, but continental crust is too weak, and too riddled with faults left over from when it was close to a plate boundary, for it to entirely hold up when subjected to the stresses of plate motion. So although a very large proportion of the Earth's earthquakes occur at plate boundaries, there is also some ........ Read more »

The fate of tall grass prairie remnants in North America...

by Rob Goldstein in Conservation Maven

North American tall grass prairie holds an unfortunate distinction of having faced one of the highest conversion rates of any ecosystem in the world. In Manitoba, 99% of the historic tall grass prairie has been lost, mostly to agriculture.

So if 99% is gone, how is the remaining 1% making out?... Read more »

Gene therapy can work!

I am basking in the reflected glory of working at an institution that has more or less successfully applied gene therapy to alleviate the suffering of children with incurable genetic diseases. And they’re fighting the good fight, because sometimes, they win. Here, I discuss how they did it, and why.... Read more »

A Small Sip from the Fountain of Youth

by Shaheen Lakhan in Brain Blogger

The search for eternal youth is as old as time itself. The theme of immortality winds its way through religion, mythology, poetry, fiction, and modern movies. Usually, stories of those who have achieved immortality expose the curse of eternal life, rather than the blessing of perpetual youth. While living forever may never be possible, life [...]...

No Beer Today

Blog writing for professionalism in medical education

Had an idea to use writing of a blog for a minor in medical education. The idea was sacrificed for other options for minors.

Lost apples found

It is an incontestable fact that of 7100 named varieties of apples grown in the United States in the 1800s, 6800 are extinct, “no longer to be seen again” according to Cary Fowler.

Friday Weird Science: The Stuttering Priapism

Who would have thought Sci would be running a normal pub-med search, for something COMPLETELY not weird science material, and come across...this? Truly, it was meant to be!

This case report is probably one of the weirdest things I've seen all week, and kept Sci scratching her head as to the possible mechanism. Also, it is, without a doubt, one of the most incredibly embarrassing thing to ever happen to a 15-year-old. And you thought YOUR teenage stories were bad...

Antivirals and resistance: Adamantanes

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

In the case of a pandemic, and during the seasonal epidemics, once a person has already contracted the influenza, we can do little, other than monitor and treat him with antivirals. However, they are not always a guarantee of success, especially in the case of resistant viruses.
Amantadine and rimantadine are the first drugs used against [...]... Read more »

It’s Not Just Carbon

by teofilo in Follow the Energy

Most of the discussion of climate change and options for mitigating it has focused on carbon dioxide emissions and the potential for reducing them.  This is reasonable enough, since carbon dioxide is by far the most abundant greenhouse gas, and it’s fiendishly difficult to do anything about once it’s emitted.  It stays in the atmosphere [...]...

Why "where" cannot be a sensory processing stream

by Greg Hickok in Talking Brains

There is debate about the nature of the dorsal auditory processing stream. Some folks, Josef Rauschecker in particular, argue for a dorsal "where" stream, whereas others, Hickok & Poeppel and Warren et al., argue for a sensory-motor integration (sometimes called "how") stream. Here's why the "where" hypothesis can't, in principle, be right. Spatial information associated with an auditory signal is a stimulus feature much like pitch. We don't talk about a "pitch stream" however. Why not? Beca........ Read more »

The Politics of Psychopharmacology

by Neuroskeptic in Neuroskeptic

It's always nice when a local boy makes good in the big wide world.
