The giant panda’s graphic pattern has stumped biologists for years … now they have an answer.

It is rare in biology that a single trait can answer questions spanning several fields of research. One such trait is plant biology’s “leaf mass per area,” a simple measurement calculated by weighing a dried leaf and dividing by its original fresh area. Leaf mass per area, or LMA, which has been measured in thousands of studies, is used in nearly every field of plant biology to make predictions of many processes and properties such as leaf photosynthetic rates, nitrogen content and plant environmental preferences.

Defined as the loss of memory due to brain injury, shock, fatigue, repression or illness, amnesia can be short- or long-term, full or partial. Renowned expert in the cognitive neuroscience of memory, York Research Chair Shayna Rosenbaum, a professor of psychology in the Faculty of Health, has spent her professional life investigating, among other things, the mystery of amnesia.

Babies in prams accompanying older siblings on the school run are twice as likely to be exposed to harmful air pollution in the morning than in the afternoon, a new study has found.

Ocean acidification is spreading rapidly in the western Arctic Ocean in both area and depth, potentially affecting shellfish, other marine species in the food web, and communities that depend on these resources, according to new research published in Nature Climate Change by NOAA, Chinese marine scientists and other partners.
