A meticulous single-cell analytical approach to study the repair process of rotavirus-caused injury in an animal model revealed that the damaged epithelium contains a variety of cell types involved in repairing it through broad coordinated responses that ultimately heal the damaged tissue.
Cities produce 60% of global greenhouse gases. Here are some ideas to fix this from a B.C. delegate at COP26
Shauna Sylvester, executive director of Simon Fraser University's Morris J. Wosk Centre for Dialogue, is leading a delegation of Canadian cities at the United Nations climate summit in Scotland where nations are laying out their plans to curb emissions and deal with the effects of climate...
As-needed pesticide use brings wild bees, increases watermelon yield without reducing corn profits
Many farmers rent bee hives to pollinate crops, but they could tap into the free labor of wild bees by adopting an as-needed approach to pesticides, a new proof-of-concept study shows.
Comparing photosynthetic differences between wild and domesticated rice
Millions of people in Asia are dependent on rice as a food source. Believed to have been domesticated as early as 6000 BCE, rice is an important source of calories globally. In a new study from the RIPE project, researchers compared domesticated rice to its wild counterparts to understand the differences in their photosynthetic capabilities. The results can help improve future rice productivity.
Researchers develop a tool to neutralize chemical weapons using rare-earth elements
Researchers at Concordia are studying the potential applications of a type of compound called metal-organic frameworks (MOFs). They have designed a new kind of microscopic structure that can rapidly mitigate chemical weapons when exposed to ultraviolet light.
Rare boomerang collection from South Australia reveals a diverse past
New research has analyzed a rare collection of non-returning boomerangs from Kinipapa (Cooper Creek), near Innamincka in South Australia's far northeast.
Closer look at unexamined interactions could improve drug purification process
The process of purifying biopharmaceutical drugs remains a costly and time-consuming challenge. A deeper understanding of how unwanted elements within biomanufactured proteins bind to the molecules developed to remove them could help researchers make purity processes more efficient, more complex, and increasingly scalable.
History of insect invasions offers insight into the future
Over the past two centuries, thousands of non-native insects have hitchhiked to the United States in packing material, on live plants, and in passenger baggage. Scientists with two U.S. Department of Agriculture (USDA) agencies and their partners used the history of live plant imports and invasion by a common group of insects to estimate the rate at which new insects are arriving and how many new...
Small but mighty NASA weather instruments prepare for launch
Working together, two instruments could open the door for a more efficient, cost-effective way to gather key information for weather forecasting.
Alberta, with largest oil industry, sends fewer reps to COP26 than any other energy province
The province with Canada's largest oil and gas industry has sent one of the country's smallest delegations to the international climate conference, where emissions from that industry are under...

Results from a recently published study suggest that efforts to reduce biological hitchhiking on live plant imports, often referred to as 'biosecurity,' are working. However, more than a century of invasion by Hemiptera insects also suggests that increased trade might offset the effects of improved biosecurity. As many as 25 percent of invading Hemiptera insects may have yet to be detected in the...
