Northern Mars Landscape Actively Changing

Sand dunes in a vast area of northern Mars long thought to be frozen in time are changing with both sudden and gradual motions, according to research using images from a NASA orbiter.

These dune fields cover an area the size of Texas in a band around the planet at the edge of Mars’ north polar cap. The new findings suggest they are among the most active landscapes on Mars. However, few changes in these dark-toned dunes had been detected before a campaign of repeated imaging by the High Resolution Imaging Science Experiment (HiRISE) camera on NASA’s Mars Reconnaissance Orbiter, which reached Mars five years ago next month.

Ants’ Ecosystem Role is ‘Key’

Research by the University of Exeter has revealed that ants have a big impact on their local environment as a result of their activity as ‘ecosystem engineers’ and predators.

The study, published in the Journal of Animal Ecology, found that ants have two distinct effects on their local environment. (more…)

He wanted to work at Microsoft. (more…)

Research Shows Good Cop Beats Bad Cop

Even the most horrible criminals feel guilt, and according to new research from the University of Montreal, playing on that sentiment might be a good way to extract a confession. In order to gain a better understanding of why and how criminals admit to their crimes, Michel St-Yves, a forensic psychologist and lecturer, and lead author Nadine Deslauriers-Varin, both of the university’s School of Criminology, worked with 221 prisoners from a federal penitentiary, analyzing the conditions under which they did or didn’t confess.

Ice Cores Yield Rich History of Climate Change

*Research project completes drilling for the year, reaching two miles below West Antarctic Ice Sheet*

On Friday, Jan. 28 in Antarctica, a research team investigating the last 100,000 years of Earth’s climate history reached an important milestone completing the main ice core to a depth of 3,331 meters (10,928 feet) at West Antarctic Ice Sheet Divide (WAIS). The project will be completed over the next two years with some additional coring and borehole logging to obtain additional information and samples of the ice for the study of the climate record contained in the core.

As part of the project, begun six years ago, the team, funded by the National Science Foundation (NSF), has been drilling deep into the ice at the WAIS Divide site and recovering and analyzing ice cores for clues about how changes in the concentration of greenhouse gases in the atmosphere have influenced the Earth’s climate over time.

‘Brain Can Learn to Overcome Sleep Apnea’

*From sound science to sound sleep*

New research from U of T could provide some restful nights for the 18 million North Americans who suffer from obstructive sleep apnea.

In a recent study that appeared in the Journal of Neuroscience, U of T scientists demonstrated that repeated obstruction of the airways requires release of the brain chemical noradrenaline. The release of this chemical helps the brain learn to breathe more effectively and purposefully. (more…)
