The effectiveness of permethrin, an important mosquito-fighting insecticide, may be impaired by global warming, according to a recent study. People involved in mosquito-control efforts should take temperature into account when choosing a pest-control product, according to Peterson. —> Read More

I don’t think I’ll ever tire of seeing pictures of Saturn’s moon Enceladus, with those captivating water jets and plumes at its South Pole. And this new images from the Cassini mission is just stunning – and intriguing. Carolyn Porco, the Cassini imaging team lead described the image on Twitter: “Be moved by crescent Enceladus with its ghostly geysers floating above Saturn’s glowing rings.”

Post submitted by Max Allen of the Santa Cruz Puma Project.
I currently work on the Santa Cruz Puma Project in California, studying pumas that live in the highly fragmented and human-dominated Santa Cruz Mountains. Pumas who live here must navigate through a landscape that is a mosaic of different levels of human activity and housing density alongside open spaces, entailing risk during run-ins with humans. The northeastern border of our study area is Silicon Valley, an area of a high density of humans and development, but human growth and development is accelerating throughout the Santa Cruz Mountains. Having previously studied pumas in a remote area in northern California, I am often surprised by the juxtaposition of a large carnivore living so close to so many people in our study area.
As you might expect, our research shows that pumas avoid areas with the most development (Wilmers et al. 2013), and areas with the most human activity (Wang et al. 2015). Juveniles seem to have the hardest time. When kittens are around 1.5 years old, they disperse, meaning that they leave their mother’s home range in search of territory of their own. Generally, the high quality territories are already occupied by adult resident pumas, and since juveniles are not ready to control prime habitat, they are often pushed by the resident animals into marginal, suboptimal habitat. In our case, this means areas closer to higher levels of human activity and development.
The yearling pumas in this video will disperse from their mother soon, and likely live in sub-optimal habitat —> Read More
Climate change may be the one thing that threatens everyone on Earth. But the peril is much more dire for people in some countries if negotiators fail to reach a climate deal in Paris in the coming weeks.
The Notre Dame Global Adaptation Index and climate risk consulting group Verisk Maplecroft both release annual rankings of nations most vulnerable to climate change based on geographical conditions and preparedness. Below are some of the countries most threatened by a warming planet.

It’s laundry day and the only clean T-shirt sports the big logo of a brand that used to be trendy but is only embarrassing now. What can you do? Wait until the tumble dryer has finished and be too late for the date or just put on the T-shirt? How you decide in a situation like this depends on a person’s ‘brand embarrassment tendency’ (BET). —> Read More
