For the past eight years, Operation IceBridge, a NASA mission that conducts aerial surveys of polar ice, has produced unprecedented three-dimensional views of Arctic and Antarctic ice sheets, providing scientists with valuable data on how polar ice is changing in a warming world. Now, for the first time, the campaign will expand its reach to explore the Arctic’s Eurasian Basin through two research flights based out of Svalbard, a Norwegian archipelago in the northern Atlantic Ocean.
Temporary episodes of dizziness or light-headedness when standing could reduce blood flow to the brain with lasting impacts.
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.
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.
