In 40 years, there will be about 3 billion additional people living on the Earth (~9.5 billion total) compared with today. With all of these new folks, it’s easy to think about the added demands of energy, food, and water required to sustain their lifestyles. And in terms of climate warming, it’s hard to escape [...]...

An open or shut case for nanotechnology secrets Should nanotechnology R&D be more open to allow it to thrive in the commercial world, or should companies working in this field be more secretive? Paradoxically, the answer seems to be that keeping secrets stifles innovation and reduces patent success.

There’s a new paper in this week’s issue of Science that suggests that growing a landscape mixed with genetically modified (GM) Bt corn and non-GM hybrid varieties of corn can be mutually beneficial to all corn farmers.
Why? They argue that the populations of GM corn knock down the populations of insect herbivores enough that, on [...]... Read more »

Consider the following:
(1) Sally hates Mary.
a. How likely is this because Sally is the kind of person who hates people?
b. How likely is this because Mary is the kind of person whom people hate?
Sally hates Mary doesn't obviously supply the relevant information, but starting with work by Roger Brown and Debora Fish in 1983, numerous studies have found that people nonetheless rate (a) as more likely than (b). In contrast, people find Sally frightens Mary more indicative of Sal........ Read more »
When we think of human population change and resource use, it’s easy to assume that more people will consume more resources, such as water, energy, and food. An important corollary is that resource limitations will limit population growth. Thomas Malthus was perhaps the most influential proponent of this idea.
However, several factors complicate this story:
(1) Affluence [...]... Read more »

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.

When we think of ‘prey’ we generally think of nourishment, but prey has other use too.

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.

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.
