Science is settled? But what if no one can replicate the experiments?

We are told by politicians that the science is settled with regard to climate change. We are also told by scientists that to criticise them is to provide a chilling effect on science. Some of those scientists even trot off to court to try to silence critics.

However, it appears the science is far from settled…especially when no one can replicate experiments or the claims made in these so-called peer-reviewed papers they submit to journals like Nature.

Science is facing a “reproducibility crisis” where more than two-thirds of researchers have tried and failed to reproduce another scientist’s experiments, research suggests.

This is frustrating clinicians and drug developers who want solid foundations of pre-clinical research to build upon.

From his lab at the University of Virginia’s Centre for Open Science, immunologist Dr Tim Errington runs The Reproducibility Project, which attempted to repeat the findings reported in five landmark cancer studies.

“The idea here is to take a bunch of experiments and to try and do the exact same thing to see if we can get the same results.”

You could be forgiven for thinking that should be easy. Experiments are supposed to be replicable.

The authors should have done it themselves before publication, and all you have to do is read the methods section in the paper and follow the instructions.

Sadly nothing, it seems, could be further from the truth.

Being outsmarted by a bird

If homosexuality isn’t natural, why does it appear in nature?

One of the main arguments against Marriage Equality is that being gay isn’t natural, and it is a choice.

Here is a summary of animals, as in, creatures of nature, as in, natural being something that is of nature, that show homosexual behaviours.

One of the most clear examples are black swans that pair up as a gay male pair, and then chase a heterosexual pair off their nest and raise the cygnets as their own.

Some more examples over the break, but only bother if you’re not easily offended by natural animals having natural gay sex

Photo Of The Day

When it comes to wild animal photography, Charles Glatzer really does get the shots that others don’t.  He must have had a very long lens to take this photo.  (Or balls of steel)

After years of being a mechanical engineer, Sandot quit his job and moved back to this family farm in Northern Thailand. Now, he works to reforest the area and create a sustainable lifestyle and culture for both his neighbors and his family by growing his own food, building bamboo houses, and living the simple life.

Hot as Hell

Andrew Sullivan

You’ve heard the saying but how hot is hell? Well…apparently it is cooler than heaven…hmmm…this is going to tax the literalists:

Isaiah 30:26 reads, Moreover the light of the Moon shall be as the light of the Sun and the light of the Sun shall be sevenfold, as the light of seven days. Thus Heaven receives from the Moon as much radiation as the Earth does from the Sun and in addition seven times seven (forty-nine) times as much as the Earth does from the Sun, or fifty times in all. …  The exact temperature of Hell cannot be computed but it must be less than 444.6°C, the temperature at which brimstone or sulfur changes from a liquid to a gas. Revelations 21:8: But the fearful and unbelieving … shall have their part in the lake which burneth with fire and brimstone. A lake of molten brimstone means that its temperature must be below the boiling point, which is 444.6°C. (Above that point it would be a vapor, not a lake.)

We have then, temperature of Heaven, 525°C. Temperature of Hell, less than 445°C. Therefore, Heaven is hotter than Hell.

Watch out for Brinicles

from Boing Boing

Here’s how polar oceanographer Mark Brandon explained the process in an article on the BBC website:

In winter, the air temperature above the sea ice can be below -20C, whereas the sea water is only about -1.9C. Heat flows from the warmer sea up to the very cold air, forming new ice from the bottom. The salt in this newly formed ice is concentrated and pushed into the brine channels. And because it is very cold and salty, it is denser than the water beneath.

The result is the brine sinks in a descending plume. But as this extremely cold brine leaves the sea ice, it freezes the relatively fresh seawater it comes in contact with. This forms a fragile tube of ice around the descending plume, which grows into what has been called a brinicle.
