Wood scientist Solace Sam-Brew envisions a future where Canadian homes are furnished with products made from flax and hemp.

“Both flax and hemp are widely available in Canada, especially in the West,” said Sam-Brew, a recent PhD graduate from the University of British Columbia’s faculty of forestry. “It’s worth considering their viability as alternative raw materials to wood for particleboard production.”

High performing lithium-ion batteries are a key component of laptops, smart phones, and electric vehicles. Currently, the anodes, or negative charged side of lithium ion batteries, are generally made with graphite or other carbon-based materials.

Just four weeks ago, fire crews battled the Sunshine fire in the foothills west of Boulder. Low humidity, record-high temperatures and 40 mile-per-hour gusts of wind helped fan flames that forced over 1,000 people to evacuate their homes. Firefighters quickly contained the wildfire, with no injuries or damage reported. But the reality of a blaze this serious in March raises concerns about how we deal with wildfire in the western United States.

When the Deepwater Horizon oil rig suffered a catastrophic explosion and blowout on April 21, 2010, leading to the worst oil spill in the history of the petroleum industry, the well’s operators thought they would be able to block the leak within a few weeks. On May 9 they succeeded in lowering a 125-ton containment dome over the broken wellhead. If that measure had worked, it would have funneled the leaking oil into a pipe that carried it to a tanker ship above, thus preventing the ongoing leakage that made the spill so devastating. Why didn’t the containment work as expected?

The culprit was an icy mixture of frozen water and methane, called a methane clathrate. Because of the low temperatures and high pressure near the seafloor, the slushy mix built up inside the containment dome and blocked the outlet pipe, preventing it from redirecting the flow. If it hadn’t been for that methane clathrate, the containment might have worked, and four months of unabated leakage and widespread ecological devastation might have been prevented.

How hot our planet will become for a given amount of greenhouse gases is a key number in climate change. As the calculation of how much warming is locked in by a given amount of emissions, it is crucial for global policies to curb global warming.

It is also one of the most hotly debated numbers in climate science. Observations in the past decade seem to suggest a value that is lower than predicted by models. But a University of Washington study shows that two leading methods for calculating how hot the planet will get are not as far apart as they have appeared.

Scientists in the world’s largest autism genomics project recently identified 18 new genes that increase risk for the condition.

Some of the genes seen in participants also carry risk for heart disease, diabetes and other conditions, opening the potential for more personalized genetic counselling.

Cretaceous climate warming led to a significant methane release from the seafloor, indicating potential for similar destabilization of gas hydrates under modern global warming. A field campaign on the remote Ellef Ringnes Island, Canadian High Arctic, discovered an astounding number of methane seep mounds in Cretaceous age sediments.

Imagine a future in which every home has an appliance that pulls all the water the household needs out of the air, even in dry or desert climates, using only the power of the sun.

That future may be around the corner, with the demonstration this week of a water harvester that uses only ambient sunlight to pull liters of water out of the air each day in conditions as low as 20 percent humidity, a level common in arid areas.

A new reconfigurable device that emits patterns of thermal infrared light in a fully controllable manner could one day make it possible to collect waste heat at infrared wavelengths and turn it into usable energy.

What is the volume of water in lakes on Earth? Using a mathematical analysis, researcher David Seekell, at Umeå University, and his American collaborators now suggest that the mean depth of lakes is 30 per cent lower than previously estimated. Shallower lakes implies less fresh water and has consequences for our understanding of climate change and the carbon cycle. The results have been published in Geophysical Research Letters.
