Warmer waters from climate change will leave fish shrinking, gasping for air

Fish are expected to shrink in size by 20 to 30 per cent if ocean temperatures continue to climb due to climate change.

A new study by researchers at the University of British Columbia provides a deeper explanation of why fish are expected to decline in size.

University of Saskatchewan, NASA team up on global water survey

Pardon the pun, but Canada is practically overflowing with freshwater.

And, believe it or not, that abundance causes problems for water researchers.

“Canada is blessed with more freshwater than anywhere else in the world, but there’s no way you can put sensors in to monitor everything,” said Al Pietroniro, executive director of National Hydrological Services, an adjunct professor with the University of Saskatchewan and member of the Centre for Hydrology. “It’s too big.”

Study: Methane from tundra, ocean floor didn't spike during previous natural warming period

Scientists concerned that global warming may release huge stores of methane from reservoirs beneath Arctic tundra and deposits of marine hydrates – a theory known as the “clathrate gun” hypothesis – have turned to geologic history to search for evidence of significant methane release during past warming events.

A new study published this week in the journal Nature suggests, however, that the last ice age transition to a warmer climate some 11,500 years ago did not include massive methane flux from marine sediments or the tundra. Instead, the likely source of rising levels of atmospheric methane was from tropical wetlands, authors of the new study say.

Manganese in Underground Drinking Water is Cause for Concern

Study on U.S. Glacial Aquifer and 3 Asian countries suggests officials should monitor manganese as a possible public health threat.

Potential Impacts of Planned Andean Dams Outweigh Benefits, Scientists Say

Scientists used historical data and models to predict the impacts of six planned or potential Andean dams on the Amazon river system.

For the love of ice: Journeys to the remote and inhospitable

Ice has always been fascinating to Alison Criscitiello.

“I had a science teacher who did a short unit on glaciers … I couldn’t believe they were real,” she says. That classroom encounter when she was in eight grade in Winchester, Massachusetts, had a lasting impact.

Caffeine tempers taste, triggering temptation for sweets

Caffeine, the widely consumed stimulant and igniter of sluggish mornings, has been found to temper taste buds temporarily, making food and drink seem less sweet, according to new Cornell University research.

This is how belly fat could increase your cancer risk

It’s been well established that obesity is a contributor to cancer risk, but how it actually causes cancer is still a question that hasn’t been fully explained.

Illegal dumping during road construction in Ethiopia affects child mortality

The research shows that an additional road built within five kilometres increases the probability that a mother experiences an infant death by three percentage points from 8.5 per cent to 11.5 per cent The research team also found that children under the age of five living near a recently built road have a lower level of haemoglobin in the blood and are more likely to suffer from severe anaemia.

New green solvent could help clean our air

French researchers have patented an eco-friendly liquid mixture that could help trap harmful pollutants from the air. The non-flammable solvent contains urea and choline salt, a common ingredient in chicken feed, says Leila Moura of the Unité de Chimie Environnementale et Interactions sur le Vivant in France. She is the lead author of a study in Springer’s journal Environmental Chemistry Letters.
