In a study that looked at data over a 10-year period, York University researchers, in collaboration with the Children’s Hospital of Eastern Ontario (CHEO) and the Institute for Clinical Evaluative Sciences (ICES), found that more than two-thirds of youth and children with an acute concussion do not seek medical followup or clearance as recommended by current international concussion guidelines.

In large parts of the developing world, people have abundant heat from the sun during the day, but most cooking takes place later in the evening when the sun is down, using fuel — such as wood, brush or dung — that is collected with significant time and effort.

Interplanetary space is hardly tranquil. High-energy charged particles from the Sun, as well as from beyond our solar system, constantly whizz by. These can damage satellites and endanger astronaut health — though, luckily for life on Earth, the planet is blanketed by a protective magnetic bubble created by its magnetic field. This bubble, called the magnetosphere, deflects most of the harmful high-energy particles.

New research, led by the Centre for Ecology & Hydrology, suggests that plant respiration is a larger source of carbon emissions than previously thought, and warns that, as the world warms, this may reduce the ability of Earth’s land surface to absorb emissions due to fossil fuel burning.

In many ways, Essen is the envy of cities trying to move past their industrial days. Once the steel and coal center of Germany, Essen’s economic success in the early 20th century was evident in the dust blanketing the city and sulfur filling the air with the constant stench of rotten eggs. By one resident’s account, coal miners permanently wore black smudges across their faces, earning them the nickname waschbar, or “raccoons.”

Leipzig. Forests fulfil numerous important functions, and do so particularly well if they are rich in different species of trees. This is the result of a new study. In addition, forest managers do not have to decide on the provision of solely one service – such as wood production or nature conservation – as a second study demonstrates: several services provided by forest ecosystems can be improved at the same time. Both studies were led by scientists from Leipzig University and the German Centre for Integrative Biodiversity Research (iDiv), and published in the prestigious journal Ecology Letters.
