As the world shifts from coal to natural gas, it is becoming more important to find ways of using natural gas efficiently and environmentally friendly. Now chemical engineering researchers have identified a new mechanism to convert natural gas into energy up to 70 times faster, while effectively capturing the greenhouse gas—carbon dioxide....

Like Mother, like baby! Photo from freedigitalphotos.net.Moms give us so much more than we ever give them credit for. Biologically speaking, we all have a mom and a dad (unless you’re a flatworm or some other species that can reproduce without sex) that provide us with one of each chromosome type (our chromosomes contain our genes, commonly thought of as our “biological blueprints”). So it makes sense that we tend to think of ourselves as being half-our-mom and half-our-dad. But not so! Al........ Read more »
A new robotic sensor deployed by Woods Hole Oceanographic Institution (WHOI) in Gulf of Maine coastal waters may transform the way red tides or harmful algal blooms (HABs) are monitored and managed in New England. The instrument was launched at the end of last month, and a second such system will be deployed later this spring.... Read more »

A recently published paper in Scientific Reports has found that climate variability in the form of the North Atlantic Oscillation (NAO) has had a significant impact on the occurrence of disease outbreaks in Europe over the past fifty years. Researchers in France and the United Kingdom studied 2,058 outbreaks occurring in 36 countries from 114 infectious diseases from 1950 to 2009 and found that climatic variations and seasonal changes in air pressure across the continent attributed to the NAO in........

As consumers, we like to hear that produce growers and distributers go above and beyond food safety mandates to ensure that healthy fresh fruits and vegetables do not carry bacteria or viruses that can make us sick. But in California’s Salinas Valley, some more vigorous interventions are cutting into the last corners of wildlife habitat, without evidence of food safety benefits, creating tensions between wildlife preservation and food safety where none need exist....

When climates change, species move. It’s a fact of life on Earth and probably has been for the past 542 million years, even when species don’t have legs or wings or fins to get them from place to place.

Ecology is a rapidly changing, dynamic field of research. In recent decades, there’s been a major shift from considering ecosystems as stable and poised to seeing them as systems that are in constant flux. At least, that’s what ecologists want (us) to believe. But how much of this claimed change has been able to seep [...]... Read more »

No man is an island, entire of itself. Although we like to think of our decisions occurring in a vacuum, in reality we’re bombarded with information on how other people are deciding all the time. It would be shocking if our decisions weren’t influenced by the behavior of other people – and, obviously, a wide range [...]... Read more »

Indian House Crow, not the prettiest... Thanks to Dick Daniels There are very few birds I don't like to see, but today's common bird is an exception - the Indian House Crow, Corvus splendens. Actually, that's probably slightly untrue, as I have been to India and I was perfectly happy to see the species there. In East Africa, however, this is not a species I'm ever happy to see. Not because there aren't interesting things to say about it, of course, but because it really belongs in India and seem........ Read more »

What are you saying with your smells? Image by freedigitalphotos.net.Animals communicate in all kinds of ways: with vocalizations, body language, vibrations, and even odors. In fact, compared to most species, we are pathetic in our abilities to communicate with body odor. With just a whiff of eau de crotch, many animals can decipher that individual’s species, sex, age, health status, reproductive status, emotional state, and dietary history. Some species can go so far as to make out that indiv........ Read more »

We can knit sweaters for oiled penguins, but it's harder to protect whales and dolphins from the harm of having us as neighbors. Loud underwater sounds from activities like sonar and drilling may damage these animals' hearing and even lead to mass strandings. Though we can't chase cetaceans around with homemade earmuffs, we might be able to teach them to tune us out.
Like squinting or letting one's pupil shrink in bright light, some animals can adjust how sensitive their ears are. When we're........ Read more »

One of the hardest questions to answer in an infectious disease outbreak investigation is "Why?"
Why then? Why there? These questions can be almost impossible to answer - not only because of their heady metaphysical nature but also because of the difficulty of assessing the minute interactions between microbe, environment and human host. Public health officials are often left shrugging their shoulders, half-heartedly admitting to an unsatisfied public that they just don't know ........ Read more »

Our close evolutionary cousin, the common chimpanzee, comes in four subspecies, each one named after its location along an East-West band in Africa. Yet, there are chimps outside of Africa as well. Many European zoos possess a group of chimpanzees, which often plays a part in conservation plans. After all, the populations of our primate brothers are in steep decline. Habitat destruction, bushmeat hunting, pet trade and disease all take their to... Read more »
