Study Of Polar Dinosaur Migration Questions Whether Dinosaurs Were Truly The First Great Migrators:

Contrary to popular belief, polar dinosaurs may not have traveled nearly as far as originally thought when making their bi-annual migration.

ADHD Appears To Increase Level Of Nicotine Dependence In Smokers:

Young people with ADHD are not only at increased risk of starting to smoke cigarettes, they also tend to become more seriously addicted to tobacco and more vulnerable to environmental factors such as having friends or parents who smoke, according to a study from Massachusetts General Hospital reseachers.

Plant-eating Predator To Fight Superweed Is Not Magic Bullet, According To Japanese Knotweed Expert:

Plans to introduce plant-eating predators to fight a superweed spreading throughout Britain should not be seen as a 'magic bullet', says a world expert on Japanese knotweed at the University of Leicester.

Ecosystem-level Consequences Of Frog Extinctions:

Streams that once sang with the croaks, chirps and ribbits of dozens of frog species have gone silent. They're victims of a fungus that's decimating amphibian populations worldwide.

Florida's 'Worm Grunters' Collect Bait Worms By Inadvertently Imitating Mole Sounds:

When biologist Ken Catania heard about the peculiar practice of worm grunting practiced in the Apalachicola National Forest in the Florida Panhandle one of his first thoughts was an observation made by Charles Darwin.

'Magnetic Death Star' Fossils: Earlier Global Warming Produced A Whole New Form Of Life:

An international team of scientists has discovered microscopic, magnetic fossils resembling spears and spindles, unlike anything previously seen, among sediment layers deposited during an ancient global-warming event along the Atlantic coastal plain of the United States.

Turtle Doves Commit Adultery:

Dutch biologist Paula den Hartog has shown that bastard doves can fend for themselves. Despite having a strange coo, hybrid offspring are still able to defend their territory. This is necessary for further reproduction.

Sugar Plays Key Role In How Cells Work:

Johns Hopkins scientists were dubious in the early 1980s when they stumbled on small sugar molecules lurking in the centers of cells; not only were they not supposed to be there, but they certainly weren't supposed to be repeatedly attaching to and detaching from proteins, effectively switching them on and off. The conventional wisdom was that the job of turning proteins on and off -- and thus determining their actions -- fell to phosphates, in a common and easy-to-detect chemical step in which phosphates fasten to and unfasten from proteins; a process called phosphorylation.

Now, after decades of investigating the "new" sugar-based protein modification they discovered, the Johns Hopkins team admits that they themselves were surprised by their latest results. Published recently in the Proceedings of the National Academy of Sciences, their findings show that the surreptitious sugar switch is likely as influential and ubiquitous as its phosphate counterpart and, indeed, even plays a role in regulating phosphorylation itself.
