How smoking encourages infection 
Now new research published in the open access journal BMC Cell Biology shows that nicotine affects neutrophils, the short-lived white blood cells that defend against infection, by reducing their ability to seek and destroy bacteria.

Stopping unwanted cell death: Implications for drug discovery
Research published in Nature Chemical Biology reveals that three specific inhibitors of a cell death pathway, termed necroptosis, all target and inhibit RIP1 kinase, a protein that can direct cells into necrosis. Induced by trauma such as a heart attack or stroke, this form of necrotic death can result in tissue damage contributing to death or long-term disability.

Data-handling technique finds genes to be team players in curbing brain cancer cell growth
The search for cancer genes is increasingly a matter of molecular “To Tell the Truth,” as scientists seek to distinguish genes actually involved in the disease from those that are imposters. Powerful gene-scanning technology often reveals hundreds or thousands of genetic irregularities in tumor tissue, making it critical for investigators to winnow out the true culprits.

Found: First lungless frog
Researchers have confirmed the first case of complete lunglessness in a frog, according to a report in the April 8th issue of Current Biology, a publication of Cell Press. The aquatic frog Barbourula kalimantanensis apparently gets all the oxygen it needs through its skin.

Fish "Eavesdropping" for Food Odors Connected to Global Climate Regulation
Climate change may be predicted by fish who "eavesdrop" their way to healthy food sources using chemical cues given off by ocean organisms. This research, conducted by the University of North Carolina Wilmington assistant professor Sean Lema and collaborators, was published in the March edition of the journal Science in the article "Dimethylsulfoniopropionate as a Foraging Cue for Reef Fishes."

Computers show how bats classify plants according to their echoes
Researchers have developed a computer algorithm that can imitate the bat’s ability to classify plants using echolocation. The study, published March 21st in the open-access journal PLoS Computational Biology, represents a collaboration between machine learning scientists and biologists studying bat orientation.

Mantis shrimp vision reveals new way that animals can see
Mantis shrimp can see the world in a way that had never been observed in any animal before, researchers report in the March 20th Current Biology, a Cell Press publication. The discovery—which marks the fourth type of visual system—suggests that the ability to perceive circular polarized light may lend mantis shrimp a secret mode of communication.

New research provides dynamic visualization of simplest circadian clock
Scientists have acquired a more dynamic picture of events that underlie the functions of a bacterial biological clock. New research published online March 13th by Cell Press in the journal Molecular Cell, shows how the simplest organism known to have a circadian clock keeps time and may enhance our understanding of how other organisms establish and govern chronological rhythms.

Invasive species can produce 'hotspots of evolutionary novelty,' study shows
When exotic species invade new territory, they often present a major threat to the other plants and animals living there—that much is clear. But researchers writing in the March 11th issue of Current Biology, a publication of Cell Press, now show that, in addition to their destructive tendencies, invasive species can also have a surprisingly “creative” side.

Listen: Naming Species Before They Disappear
Gustavo Hormiga is an arachnologist and a taxonomist, that is, a scientist who discovers, classifies and names life on earth. Taxonomy is one of the oldest fields of biology, but for a long time it seemed a little fuddy-duddy and out of fashion. In an age of climate change and growing habitat destruction, however, Hormiga says it couldn't be more hip or important.

Scientists funded by the Biotechnology and Biological Sciences Research Council (BBSRC) have published new research in the journal Molecular Pharmacology identifying the structure of a receptor in the brain implicated in conditions such as epilepsy and pre-menstrual tension. The same receptor has also been reported to be highly sensitive to alcohol.
