Ants, like humans, deal with disease. To deal with the bacteria that cause some of these diseases, some ants produce their own antibiotics. A new comparative study identified some ant species that make use of powerful antimicrobial agents – but found that 40 percent of ant species tested didn’t appear to produce antibiotics. The study has applications regarding the search for new antibiotics that can be used in humans. (more…)

Columns of workers penetrate the forest, furiously gathering as much food and supplies as they can. They are a massive army that living things know to avoid, and that few natural obstacles can waylay. So determined are these legions that should a chasm or gap disrupt the most direct path to their spoils they simply build a new path — out of themselves. (more…)
Ants can lift up to 5,000 times their own body weight, new study suggests
COLUMBUS, Ohio — High hopes may help move a rubber tree plant (as the old song goes), but the real secret to the ant’s legendary strength may lie in its tiny neck joint.
ANN ARBOR, Mich.— Predatory beetles can detect the unique alarm signal released by ants that are under attack by parasitic flies, and the beetles use those overheard conversations to guide their search for safe egg-laying sites on coffee bushes.
Azteca instabilis ants patrol coffee bushes and emit chemical alarm signals when they’re under attack by phorid flies. In an article published online July 27 in the journal Ecology and Evolution, University of Michigan researchers and their colleagues show that pregnant lady beetles intercept the ants’ alarm pheromones, which let the beetles know that it’s safe to deposit their eggs.

Predators select their prey in order to eat a nutritionally balanced diet and give themselves the best chance of producing healthy offspring.
A University of Exeter and Oxford-led study published in Proceedings of the Royal Society B shows for the first time that predatory animals choose their food on the basis of its nutritional value, rather than just overall calorie content.
An international team of scientists from the Universities of Exeter and Oxford in the UK, University of Sydney (Australia), Aarhus University (Denmark) and Massey University (New Zealand) based their research on the ground beetle, Anchomenus dorsalis, a well-known garden insect that feasts on slugs, aphids, moths, beetle larvae and ants.

Scientists seeking to understand the origin of the human mind may want to look to honeybees — not ancestral apes — for at least some of the answers, according to a University of Colorado Boulder archaeologist.
CU-Boulder Research Associate John Hoffecker said there is abundant fossil and archaeological evidence for the evolution of the human mind, including its unique power to create a potentially infinite variety of thoughts expressed in the form of sentences, art and technologies. He attributes the evolving power of the mind to the formation of what he calls the “super-brain,” or collective mind, an event that took place in Africa no later than 75,000 years ago. (more…)
Research by the University of Exeter has revealed that ants have a big impact on their local environment as a result of their activity as ‘ecosystem engineers’ and predators.
The study, published in the Journal of Animal Ecology, found that ants have two distinct effects on their local environment. (more…)
Normally we are used to see Hollywood Gala, Stars Gala, and some more different types of gala, where mainly movie stars are the main attractions. Then comes directors, producers, etc. etc. Needless to mention about the music galas.
However, this time it’s ‘Ants Gala’. We all know them from our childhood. They are everywhere, in every continent – all over the Earth. So now it’s there Gala. 🙂
