It was just a couple weeks back when I brought you troubling information found by the Center for Biological Diversity (buried in the Imperial Irrigation District report) regarding the state of burrowing owls in the Imperial Valley. Those surveys showed a 27% decline in breeding burrowing owls in what is California’s largest population. Well, I [...]... Read more »

When we think of ‘prey’ we generally think of nourishment, but prey has other use too. Jackson & Pollard report on a fascinating case in which the ant-snatching assassin bug (Acanthaspis petax) makes a “backpack” of its victims to avoid being seen by its own predator, the deadly jumping spider. Masking to avoid [...]... Read more »

There are no truly universal laws in ecology. Every pattern and process takes place on its own scale in time and space, and truths that hold at one scale do not necessarily hold at another. This is a fact of life anyone dealing with an ecosystem has to come to terms with, whether they are [...]... Read more »

There has been a lot published recently on the source of happiness and what constitutes the good life, with many articles focusing on levels of personal income that mark tipping points, such as the recent claim that we need $75,000 to be happy.

Physiognomy is a debunked pseudo-science which claimed to describe characterisics solely from the face. The Illusrated Annuals of Phrenology & Physiognomy (1866) define Physiognomy as the "science of external forms in their relation to internal organisation and character," In 1886, Samuel Wells edited a paper suggesting characteristics of statesmen at the time, and what characteristics a statesman would need in order to be an effective man of the people. Wells (1889) initially maintains that ........ Read more »

At this time of year, as the weather turns colder and the nights become longer, one can't help but be thankful for our home. Some people never leave home, and some miss it terribly so. In contrast some don't, and do not care about their home, why is this? Today's article is concerned with the home, the importance of owning a home, and characteristics, even animal characteristics, that can be given to homeowners in order to understand what kind of home they might build and where.

Every year, the crew behind the Annals of Improbable Research honor research that "first makes people laugh, then makes them think." These awards, known as the Ig Nobels, honor some of the most entertaining research published in the past year. The competition is fierce, and the prizes highly coveted. But without further ado!

Critics call them “frankenfish.” Advocates call them delicious. Either way, a genetically engineered salmon may be served up on your plate sooner than you think.

Water security is making a bit of a splash this week.

Genetically modified organisms (GMOs) are back in the news. A few days ago, NPR featured a couple of blog posts (here and here) considering whether the new GMO “supersized” salmon will be harmful to aquatic ecosystems.
A concern with GMOs is that—like the early adoption of pesticides—potential risks are being borne by the environment and consumers [...]... Read more »

I’ve got a few news items regarding IMG, or Integrated Microbial Genomes, from the DOE Joint Genome Institute. The first item is that their Sept 2010 release occurred this week. IMG is now on version 3.2, has updated features and a bunch of new/revised genomes. I’ve begun updating our tutorial & will let you know when that is released. It’s not the craziest level of tool changes that I’ve seen from this group, but dang, they SURE don’t rest on their laurels! The........ Read more »

The rise in global mean temperature of about 0.9 degrees C over the 20th century is one of the most well-known trends in the science of global change.

Still too many cooperations do not analyze their supply networks using consistent and scientifically proven methods. Some already do. One case of a company (ABC) is described below.
