The secret of empathy

The ability to express empathy -- the capacity to share and feel another’s emotions -- is limited by the stress of being around strangers, according to a new study published today in the journal Current Biology.

Isotopic memory of atmospheric persistence

Chemical analysis of some of the world’s oldest rocks, by an international team led by McGill University researchers, has provided the earliest record yet of Earth's atmosphere. The results show that the air 4 billion years ago was very similar to that more than a billion years later, when the atmosphere -- though it likely would have been lethal to oxygen-dependent humans -- supported a thriving microbial biosphere that ultimately gave rise to the diversity of life on Earth today.

A place in the top 10

Research led by Prof François Barthelat in the Department of Mechanical Engineering earned a spot on Quebec's list of top 10 scientific discoveries in 2014. Inspired by natural structures like seashells, Barthelat and his team developed a technique to strengthen glass. They were able to make glass 200 times more resistant to breakage by engraving micro-cracks in wavy configurations on its surface. The pattern of micro-cracks guided larger cracks and absorbed impact energy.

It’s all in a good night’s sleep

Making sure school-aged kids get to sleep at a regular hour is often a struggle for parents. But a study by researchers at McGill University and the Douglas Mental Health University Institute in Montreal suggests it’s well worth the effort: the researchers found that a good night’s sleep is linked to better performance in math and languages – subjects that are powerful predictors of later learning and academic success.

Social equity in urban transportation planning

During the 20th century, urban transportation planning in North America was mainly concerned with easing traffic congestion, improving safety and saving time for motorists. These days, most cities’ transportation plans evoke a more complex blend of environmental, economic, and social-equity goals – all aimed at promoting “sustainability.” Yet, many fail to include meaningful measurements of social-equity objectives, such as helping disadvantaged neighborhoods access essential services, according to researchers at McGill University.

Better dam planning strategies

When dams are built they have an impact not only on the flow of water in the river, but also on the people who live downstream and on the surrounding ecosystems. By placing data from close to 6,500 existing large dams on a highly precise map of the world’s rivers, an international team led by McGill University researchers has created a new method to estimate the global impacts of dams on river flow and fragmentation.
