The 2010 floods were among the worst that Pakistan has experienced in recent decades. Sadly, the country is prone to recurrent flooding which means that in any given year, Pakistani farmers hope and pray that the floods will not be as bad as those in 2010. It would be natural to assume that recurring flood disasters force Pakistani farmers to give up farming and migrate to the cities in order to make ends meet. But a recent study published in the journal Nature Climate Change by Valerie Mueller ........ Read more »

European hamsters showed us that there is more to annual body rhythms than melatonin. Image by Agnieszka Szeląg at Wikimedia Commons.Many animals undergo seasonal physiological changes in order to ensure that their babies are born during a time of more abundant food and milder weather and to help their bodies prepare for harsh winter conditions. In order to precisely time these physiological changes with the seasons, most animals have evolved to respond to the most reliable marker for time of y........ Read more »

Let’s be honest, we’ve been getting a little fancy with the antibiotics, creating new and more relevant versions of old favorites like penicillin. Truthfully, we are the problem, how many times do we have to drive home the idea that antibiotics are for bacteria, not viruses. It is not all the consumers fault, the Doctors used to hand out antibiotics to placate angry parents of sick children.... Read more »

Imagine you're on a particularly boring leg of a road trip and you start counting houses. You pass through long stretches of country without counting anything. When you do see houses, they're clustered into towns, and may have spacious yards with tire swings. As you approach a city (finally!), rows of houses appear at regular intervals instead of clumping. And in the heart of the city they shrink into little apartments that go by too fast for you to count. European rabbits, it turns out, b........ Read more »

Europe and other funding agencies are very attentive to interdisciplinarity and trans-sectoral activities. Their ever growing demand for multi- and trans-disciplinary science is reaching such a level that making Ecology and getting funding for it becomes a challenge. Is there a way around it?

By Rachael Pahl Sex is a dangerous, but necessary, part of life. Across the animal kingdom, there are a multitude of things that can go wrong. You could be injured in a fight by someone who wants to steal your mate, or maybe your partner eats you because you’re taking too long. Either way, nature must have a pretty good reason for the traumatizing effects of sex. A male bed bug traumatically inseminates a female.

Try to read up on the okapi and you won't find much. This African mammal is most often seen next to the adjective "elusive." But even if we can't find any okapi, we can learn about their lifestyle through their DNA—and we can find their DNA in their feces.
The okapi is an ungulate, like a cow. Or really like a giraffe, its closest relative. It has an elegant face, a long bluish tongue, and a zebra-striped rear end. It lives in the dense rainforest of the Democratic Republic of Congo, che........ Read more »

People freak out when they hear mercury is in something and sometimes for good reasons. In vaccinations for example a very small amount of ethyl-mercury WAS used as a preservative in vaccines, people got scared so now it is not used in most vaccines. Methylmercury* however is found in seafood and larger fish in particular (in much, much higher concentrations than in vaccines mind you). They may sound the same, but the methylmercury in fish is far more toxic. That said, it turns out that fish isn........ Read more »

If a polar bear tells you to talk to the hand, don't be offended. The animals seem to communicate with each other through scent trails left by their paws. Their tracks tell a story to the other bears roaming their habitat, helping potential mates to find each other—as long as there's habitat left, anyway.
As they crisscross the snowy Arctic, polar bears are usually alone. In other solitary bear species, animals leave messages for each other by rubbing their bodies or urine onto trees or........ Read more »

Make hay while the sun shines is the great lesson from renewable energy. Solar and wind have to be harvested when they occur, or they are lost forever. But how do you store that energy if the national grid doesn’t need it at that moment? Large-scale energy storage is the wave of the future – including pumping air or hydrogen gas into abandoned mines or running the national grid from all our electric cars.... Read more »
