One of the scenarios that is often played out in science fiction is what would happen if we encountered an alien civilization. Often, we are portrayed as defending Earth from an alien invasion or fighting battles with the aliens in a war. Another scenario, commonly found in more culturally introspective fiction, focuses on what our … Continue reading Beasts or gods; why a War Of The Worlds is very unlikely

Biologists continue to debate genes versus gene expression
PZ Myers has posted his views on David Dobb's Aeon article: That’s the peril of a historically successful, productive research program. We get locked in to a model; there is the appeal of being able to use solid, established protocols to gather lots of publishable data, and to keep on doing it over and over. … Continue reading Biologists continue to debate genes versus gene expression

Soothing the fear of death
The fear of death is a normal, natural, instinct that we all have. Without it, we’d end up doing all kinds of reckless things that most of us avoid. Some people claim not to fear it, but I suspect that all of us, when we’re honest, retain that fear to one degree or another. After … Continue reading Soothing the fear of death

Why is defining life so frustratingly difficult? Why have scientists and philosophers failed for centuries to find a specific physical property or set of properties that clearly separates the living from the inanimate? Because such a property does not exist. Life is a concept that we invented. On the most fundamental level, all matter that … Continue reading Why Life Does Not Really Exist | Brainwaves, Scientific American Blog Network
Why it’s time to lay the selfish gene to rest – David Dobbs – Aeon
The grasshopper, he noted, sports long legs and wings, walks low and slow, and dines discreetly in solitude. The locust scurries hurriedly and hoggishly on short, crooked legs and joins hungrily with others to form swarms that darken the sky and descend to chew the farmer’s fields bare. Related, yes, just as grasshoppers and crickets … Continue reading Why it’s time to lay the selfish gene to rest – David Dobbs – Aeon
BBC News – ‘Memories’ pass between generations
Experiments showed that a traumatic event could affect the DNA in sperm and alter the brains and behaviour of subsequent generations. A Nature Neuroscience study shows mice trained to avoid a smell passed their aversion on to their "grandchildren". More at BBC News - 'Memories' pass between generations. I saw this yesterday, but was reluctant to link … Continue reading BBC News – ‘Memories’ pass between generations
