Modeling the restless brain

...r researchers consider just background noise to be fascinating and important. Brains are always active, even when people are at rest. In this "resting state," waves of neural activity ripple through the brain, creating fluctuating and ever-changing patterns. Sporns and Honey's work on modeling this brain acti...

Undergraduate research shows leaderless honeybee organizing

...o understand how bee colonies work, but it is also fascinating because they are so different. Evolutionarily, they got to the same point as humans – living in these highly organized societies that function with remarkable efficiency -- but they are organized so differently when you start digging into them,” Sc...

Prenatal cocaine's lasting cellular effects

...edominantly sequestered inside the cells. "The fascinating thing is that this effect appears permanent," said Stanwood. This implies that cocaine exposure during a brief, sensitive period of neural development can lead to long-lasting effects at the cellular level. This change also altered the growth of...

Rewarding fat rats

...vation in animals ?and also in humans ?is not only fascinating for me, but also highly rewarding. More broadly, there is an exciting confluence of work emerging from both major branches of NSERC-supported research: natural science and engineering," says Shizgal.

Tarantula venom and chili peppers target same pain sensor

...uron receptors, the scientists conclude. "It is fascinating that plants and animals have evolved the same anti-predatory mechanism to generate noxious sensations," Julius said. "These toxins are incredibly useful for understanding how ion channels of the nervous system work. They give us clues as to how speci...

Mayo researchers discover HIV dependence on a human protein

...to establish its permanently integrated state is a fascinating question," says Eric Poeschla, M.D., the Mayo Clinic virologist who led the research. "It's critical to understand this better because permanently integrated viruses in long-lived cells prevent elimination of HIV. In the future, it will be of interes...

Computer scientists unravel 'language of surgery'

Cellular traffic backups implicated in skeletal malformations

...sible for that sort of phenotype." "For me, it's fascinating that the gene we have found was the least expected." It turns out that the zebrafish mutant has a human counterpart, making the crusher mutant the first animal model that links ER to Golgi protein transport to a human craniofacial birth defect. ...

Dragonfly's metabolic disease provides clues about human obesity
