These two articles sit rather nicely together; one discusses leaf-cutter ants, which use leaves as food for underground fungus farms and the second article discusses how bees find new homes after a beehive reaches capacity. In both examples we see...... Read more »

Each year, we hear that people are gaining weight and that chronic health problems like obesity, heart problems, and diabetes are on the rise. It's commonplace to ascribe these trends to personal lifestyle choices, such as the lack of exercise and diet, as well as the increasingly pervasive nature of fast food and processed, high-sugar foods.
However, there may [...]... Read more »

In the Policy Forum of today’s issue of Science, a research team that includes recent Nobel laureate, Elinor Ostrom, issued a call for innovative interdisciplinary approaches to confronting major environmental challenges:
Tremendous progress has been made in understanding the functioning of the
Earth system and, in particular, the impact of human actions. Although this
knowledge can inform management [...]... Read more »

The internet has changed fundamentally the way we communicate, the way we work, even the way we live our lives. That much is obvious to anyone who has ever shopped at Amazon, looked up a reference on PubMed, or gone social via Facebook.

There have been several critiques of geoengineering as a climate mitigation tool. Two of the most incisive, in my opinion, come from science and ethics.
The first is a 2007 paper in PNAS by Matthews and Caldeira showing that if we establish aerosol clouds or space reflectors while doing nothing to reduce carbon emissions, we run [...]... Read more »

When it comes to bad science in movies, there are two main camps; those who hate it, and those who hate it but will put up with it. Some say even horrid films can make the audience enthusiastic about science and make them want to learn. Then there are those who think bad science is [...]... Read more »

According to an oft-cited paper by Marcel LaFollette, a 1926 magazine once introduced an eminent medical researcher as a woman whose mahogany furniture “gleams”. From the same study, but a 1950 magazine, a senior figure in the Atomic Energy Commission was praised for sewing her own clothes. Later, via Dorothy Nelkin, Maria Mayer (Nobel physics [...]...

Today I finally read one of the most cited articles on subjective risk in general. In 1987 March and Shapira set out to shake up the existing theories on the perception and processing of risks by managers. Accordingly, they aggregated the information from various surveys on this topic.
The article is called "Managerial Perspectives on Risk and Risk Taking" and it can be downloaded here as PDF and I really recommend reading it.
In the first part I will analyze major empirical findings on ho........ Read more »
In an interesting new article in Climatic Change, Christopher Doughty and colleagues at Stanford consider whether raising crop albedo (reflectivity) could decrease solar absorption at the Earth’s surface and cool regional climates. One might consider this a kind of climate “bio”engineering.
How could you do this, and would it work?
Many desert plants have hair-like projections that [...]... Read more »

As children, one of my and my sister’s favorite rainy-afternoon activities was looking through our Mother’s jewelry box. The daughter of a forester and the wife of a teacher, my Mom didn’t have dazzling diamonds and sapphires, but she did have interesting things.

Today I read a rather old article from 1995 about "Organizational Risk Perception and Reduction: A Literature Review" by Vincent-Wayne Mitchell, now at the Cass Business School in London. I present it here since I think most of the concepts and strategies are still valid.
Objective and Methodology
The objective of Mitchell was to show the status of current research on how risks are perceived in organizational buyer behavior and what can be done to reduce these risk. He therefore conducts ........ Read more »

Right up there with climate change, biodiversity conservation is one of the most challenging issues at the intersection of nature and culture. Part of this challenge arises because of genuine differences in how people value other species.
In an interesting forthcoming article in Conservation Biology, Chris Sandbrook and colleagues at Cambridge University argue that these value [...]... Read more »
How does rebel access to natural resources affect conflict? "How". Not "if". That is the question investigated by Päivi Lujala of the Norwegian University of Science and Technology, recently published in the Journal of Peace Research.
Or rather: Where previous research has either suggested a link or sought to explain it by an indirect effect through resource abundance tending to corrupt weak ... Read more »

Perhaps one of the most important roles that science teachers play, apart from helping their students become excited about and learn science, is being a mentor to an apprentice or beginning teacher. My own experience in the mentoring process was as a beginning teacher at Weston High School where I was mentored by Irv [...]
