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

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

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.

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.

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.

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.

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.

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

Artificial-intelligence research has been transformed by machine-learning systems called neural networks, which learn how to perform tasks by analyzing huge volumes of training data.

During training, a neural net continually readjusts thousands of internal parameters until it can reliably perform some task, such as identifying objects in digital images or translating text from one language to another. But on their own, the final values of those parameters say very little about how the neural net does what it does.

A Boeing 747 burns one gallon of jet fuel each second. A recent analysis from researchers at the University of Illinois estimate that this aircraft could fly for 10 hours on bio-jet fuel produced on 54 acres of specially engineered sugarcane.
