Forest Regeneration Project of 30 Years Yields Results

A spruce forest regeneration experiment in Interior Alaska that spanned nearly 30 years demonstrates which forest management practices produce the best results.

NASA Finds Some Strength in New Eastern Pacific Tropical Depression

NASA's Aqua satellite measured cloud top temperatures in newly formed Tropical Depression 15E in the Eastern Pacific Ocean and found some strong storms. 

Irma's Heavy Rainfall Measured by NASA's IMERG

NASA calculated the rainfall left in the wake of now post-tropical cyclone Irma as it moved through the Caribbean Sea to landfall in Florida and then captured a night-time look at the storm as it moved over Georgia.

Stanford researchers study the relationship between nectar microbiomes and pollination

Dipping its beak into the sweet nectar of a flower, a hummingbird is doing more than getting a meal – it’s contributing to a microbial community that could potentially determine the fate of that flower. Recognizing that this fleeting interaction could have major implications on crop success and the health of pollinator species, the research group led by Tadashi Fukami, an associate professor of biology at Stanford, has studied the relationships between pollinators, microbes and plants for nearly a decade.

NASA Satellites Find Wind Shear Affecting Hurricane Jose

Vertical wind shear is weakening Hurricane Jose as it makes a cyclonic loop in the western Atlantic Ocean. NASA's Aqua satellite provided an image of Jose that shows the hurricane had become asymmetrical because winds were pushing the clouds away from the center of circulation and the GPM Satellite saw the strongest rainfall in Jose southeast of the center.

New Model of Climate-Change Effects on Coffee Availability and Bee Pollinators

Areas in Latin America suitable for growing coffee face predicted declines of 73-88 percent by 2050. However, diversity in bee species may save the day, even if many species in cool highland regions are lost as the climate warms. The research, co-authored by David Roubik, senior scientist at the Smithsonian Tropical Research Institute, will be published in an early online Proceedings of the National Academy of Sciences edition between Sept. 11-15.

Study Sets New Distance Record for Medical Drone Transport

Johns Hopkins researchers have set a new delivery distance record for medical drones, successfully transporting human blood samples across 161 miles of Arizona desert. Throughout the three-hour flight, they report, the on-board payload system maintained temperature control, ensuring the samples were viable for laboratory analysis after landing.

Taking the Long View: The 'Forever Legacy' of Climate Change

A century or two from now, people may look back at our current era — with its record-breaking high temperatures year after year, rapid disappearance of Arctic sea ice, and gradually rising sea levels — as part of a much cooler and far more desirable past. The spate of extreme weather events in the past month — which have devastated America’s fourth-largest city, Houston; spawned a massive hurricane that tore through the Caribbean and Florida; and swamped large swaths of India and Bangladesh — may well be a prelude to more monster hurricanes, Biblical rain events, and coastal inundations brought about by extreme weather and vastly higher sea levels.

Carleton Professor Helps Maple Syrup Producers Solve Mould Problem

Maple syrup has been a Canadian staple for centuries and although many food-manufacturing processes have become automated, maple syrup is still largely made by small producers and bought from roadside stands and markets.

The Ontario Maple Syrup Producers Association (OMSPA), which represents more than 600 producers across the province, noticed there was a problem with this value chain. After receiving a large number of complaints about mould in maple syrup,­ OMSPA called in Carleton Chemistry Prof. David Miller — an expert on fungi and fungal toxins in food — to see if he could crack the sugary conundrum.

New Canadian telescope will map largest volume of space ever surveyed

A Canadian effort to build one of the most innovative radio telescopes in the world will open the universe to a new dimension of scientific study. The Honourable Kirsty Duncan, Minister of Science, today installed the final piece of this new radio telescope, which will act as a time machine allowing scientists to create a three-dimensional map of the universe extending deep into space and time.

The Canadian Hydrogen Intensity Mapping Experiment, known as CHIME, is an extraordinarily powerful new telescope. The unique “half-pipe” telescope design and advanced computing power will help scientists better understand the three frontiers of modern astronomy: the history of the universe, the nature of distant stars and the detection of gravitational waves
