  Dengue-resistance Spreads in Mosquitoes
Australian researchers have added an additional tweak to the strain of bacteria they used to infect mosquitoes carrying the dengue virus, and shown that it can spread effectively throughout a local population of mosquitoes in the wild, according to Nature. The lab’s earlier work had demonstrated that a strain of Wolbachia pipientis, a bacterium that infects insects, could halt the reproduction cycle of the dengue virus. While the exact mechanism is unknown, the bacteria likely "compete for limited sub-cellular resources required by the virus for replication," lead author Scott O'Neill from Monash University in Melbourne, Australia told Nature.
  Satellites Spy on Fish Farms
The fishing industry is notorious for underreporting the number of organisms that are being fished out of the world’s oceans every year. To this end, publicly available satellite imagery may prove a valuable tool for monitoring fishing practices worldwide as well double checking official data released by countries and organizations.
  Fukushima Birds Affected
Even low levels of radiation are already affecting bird populations near the Fukushima Daiichi nuclear disaster, according to a new study in Environmental Pollution. Surveying birds in Fukushima Prefecture, an international team of scientists showed that higher levels of radiation correlated with smaller populations. The scientists attribute this to the fact that the power plant’s malfunction occurred in March, early in the breeding season.
  Boozing for Better Health
An apple a day keeps the doctor away, but what about a shot of tequila? It seems to work for fruit flies: Drosophila melanogaster seek out alcohol to kill off parasitic wasps living in their blood. Alcohol exposure also discourages the wasps from laying their eggs in the fly larvae in the first place. The research, published today (February 16) in Current Biology, is the first evidence that animals may use alcohol to fight infection, the authors say.
  Climate Conflict of Interest?
Just days after a prominent scientist admitted he deceitfully obtained confidential materials from the Heartland Institute, a Chicago-based organization devoted in part to questioning global warming, the scandal involving those documents has grown wider, the Chronicle of Higher Education reported. On Wednesday (February 22), Greenpeace sent letters to six universities whose faculty members were named in the stolen Heartland documents as receiving payments from the organization. The letters suggest the payments violated the disclosure policies of the universities and the National Science Foundation, which funded some of the work, the Chronicle reported.
  One Year On
Damage to nuclear reactors and buildings at the Fukushima Daiichi nuclear power plant following the earthquake and subsequent tsunami that struck Japan on March 11, 2011, resulted in the second-largest release of radioactive substances into the environment since the start of nuclear power production, and the largest accidental releases in history to the marine environment. Only the Chernobyl disaster surpassed it in magnitude.
  Antarctic Invasion
Antarctica is the coldest, driest, windiest place in the world, and is often considered the most isolated and pristine. But now, because of human impacts, the Earth’s southernmost continent is rapidly changing—not least of all due to the alien species humans are unintentionally introducing, according to a study published today (March 5) in the Proceedings of the National Academy of Sciences.
  Lions Up Close
The BeetleCam is back! And this time, it’s lion proof. The new, improved, and heavily armored version of the remote controlled, four-wheel camera buggy that met an untimely death in the jaws of a curious lioness in Tanzania in 2009 headed to the African savannah and captured stunning images of lions in Masai Mara, Kenya.
  More Maternal Effort Means More Robust Offspring
Animals faced with an infection may choose to focus on producing higher quality current offspring instead of trying for more broods later, according to a new study on house wrens. Published Wednesday (March 28) in the Proceedings of the Royal Society B, the study also suggests that, depending on their gender, fledglings may respond differently to the increased resources their parents allocate them. Male hatchlings of mothers with a simulated bacterial infection grew larger while female offspring showed stronger immune responses.
  Pesticide Problems for Bees
Two studies published online March 29 in Science hint that a specific class of pesticides, neonicotinoids, could be contributing to colony collapse disorder in bees. In one study, bumble bees exposed to a neonicotinoid produced fewer queens, while honey bees had trouble finding their way home, reported BBC News. These side effects of pesticide exposure could play a role in colony collapse disorder, the researchers say, and more thorough toxicity tests should be performed before new pesticides are approved for use.
  Ants Share Pathogens for Immunity
Ants put an active effort into developing social immunity, the phenomenon whereby contact with infected individuals can confer resistance to the community, according to a study published today (April 3) in PLoS Biology. Ants will groom their fungus-infected nestmates more, which promotes minor fungal infections that spur a fungus-specific immune response, similar to “chickenpox parties” popular before the development of the chickenpox vaccine.
