Video Games Enhance Visual Attention

by A. Goldstein in WiSci

Video games might cause aggressive behavior,1 and they may contribute to childhood obesity,2 but recent research by Daphne Bavelier and her colleagues at the University of Rochester suggests that playing video games can have at least one benefit: they enhance visual attention. Visual attention is the mental mechanism we use to select relevant visual information [...]... Read more »

A Creationist Blog Quote Mines Peer Reviewed Research about Protein Evolution

by Greg Laden in Greg Laden's Blog

It is difficult to imagine how point mutations, a large number of which are neutral, a certain number of which are deleterious, and a tiny number of which are fitness-enhancing, can add up to the sorts of evolutionary diversity and adaptive elegance we see in real life. However, there are only two possible explanations for what we see in nature: 1) Evolution happened more or less as we think it did or 2) God created life and made it look exactly like evolution happened. Take your pick. I'm be........ Read more »

Sub-Social Spiders Give New Meaning to the Term ‘Yummy Mummy’

by Dr. Carin Bondar in Dr. Carin Bondar - Biologist With a Twist

The sub-social spider Stegodyphus lineatus is one of the few invertebrate species to provide parental care.  Females provide regurgitated food meals to their offspring for a two-week period after they hatch – the only food they consume during this time.  You might imagine that it’s important for mommy to make sure that her diet is [...]...

Hearing, Reading Disabilities and PCB exposures

by ABK in Environment and Health

I found this article very exciting. Serum PCB Concentrations and Cochlear Function in 12-Year-Old Children. by Trnovec et al. 2010, in which they describe associations between hearing function and PCB exposures in Slovakian kids. (In regular terms: PCB exposure in children probably causes hearing deficits). My forebears were deaf, graduated from the American School for the Deaf, were members of Deaf Baseball and Football teams, and from all the old pictures we have, seem to have had absolute........

Why has this winter been so cold in Europe?

by Andy Russell in Our Clouded Hills

I’ve written a couple of posts recently looking at the cold UK weather in context and how snow forms. What I haven’t done, though, is looked at why it’s been so cold over Europe this winter (as well as last year’s winter). It just so happens that a paper came out in the Journal of [...]...

Where Have All the Sauropods Gone?

by Brian Switek in Dinosaur Tracking

For the past century, paleontologists have been trying to figure out one of the most puzzling disappearing acts in the fossil record. In both Europe and North America, the Jurassic was the heyday of the sauropod dinosaurs. After the beginning of the Cretaceous period 145 million years ago, however, the number of these dinosaurs dwindled [...]... Read more »

How to swap a gearbox for a new model right on the highway

by Vasili Hauryliuk in stringent response

Protein biosyntheses is central a hub for cellular physiology: proteins are essencial for all the cellular processes. Therefore changing something really important in translational machinery is really hard: you still need producing proteins! Swapping an important translational factor for another one? That sounds impossible, but this is exactly what happend with eEF1A - eukaryotic factor that brings aminoacylated tRNA to the ribosome. Moreover, it happened several times!It was indeed swapped for ........ Read more »

Why pregnant women deserve drug trials

by Melinda Moyer in Body Politic

It’s easy to gloss over health care disparities until they start really affecting you or your loved ones. When I became pregnant this summer, I discovered that there is a dearth of information available about drug safety during pregnancy. (I wrote a little about it in this Slate article published in July.) Women who rely on medication get pregnant—for instance, one in eight pregnant women takes antidepressants—and pregnant women develop complications that require medicine. Yet the only........

Sources sinks = swarmers stalks: a signaling activity gradient within a bacterial cell

by Becky in It Takes 30

You’re probably familiar with the idea that gradients of signaling molecules determine cell fate in early animal embryos.  Now, a recent paper from the Laub lab (Chen et al. 2010.  Spatial gradient of protein phosphorylation underlies replicative asymmetry in a bacterium, PNAS doi:10.1073/pnas.1015397108) has discovered gradients of active signaling molecules within a single bacterial cell.  [...]...
