New Orleans Greenery Post-Katrina Reflects Social Demographics More Than Storm Impact

Popular portrayals of “nature reclaiming civilization” in flood-damaged New Orleans, Louisianna, neighborhoods romanticize an urban ecology shaped by policy-driven socioecological disparities in redevelopment investment, ecologists argue in a new paper in the Ecological Society of America’s open access journal Ecosphere.

Wolves Understand Cause and Effect Better Than Dogs

A rattle will only make noise if you shake it. Children learn this principle of cause and effect early on in their lives. However, animals like the wolf also understand such connections and are better at this than their domesticated descendants. Researchers at the Wolf Science Center of the Vetmeduni Vienna say that wolves have a better causal understanding than dogs and that they follow human-given communicative cues equally well. The study in Scientific Reports provides the insight that the process of domestication can also affect an animal’s causal understanding.

The Body's Own Fat-Metabolism Protects Against the Harmful Effects of Sugar

For several years, medical researchers, doctors and dieticians have known that a low carbohydrate diet and plentiful fat can prevent a range of lifestyle and age-related diseases and thus promote healthy aging. But researchers from around the world have not been able to explain why this is the case. They have just been reasonably certain that the energy metabolism and its chemical intermediates (metabolites) play a central role.

Arctic Sea Ice Once Again Shows Considerable Melting

This September, the extent of Arctic sea ice shrank to roughly 4.7 million square kilometres, as was determined by researchers at the Alfred Wegener Institute, the University of Bremen and Universität Hamburg. Though slightly larger than last year, the minimum sea ice extent 2017 is average for the past ten years and far below the numbers from 1979 to 2006. The Northeast Passage was traversable for ships without the need for icebreakers.

Water Conservation Can Have Unintended Consequences

Conventional wisdom dictates water conservation can only benefit communities affected by drought. But researchers at the University of California, Riverside have deduced that indoor residential conservation can have unintended consequences in places where systems of wastewater reuse have already been implemented, diminishing both the quantity and quality of influent available for treatment.

Study Adds to Evidence That Racial and Economic Factors Affect Surgical Pain Management

A “look back” analysis of more than 600 major colorectal surgeries using a “checklist” tool has added further evidence that racial and socioeconomic disparities may occur during many specific stages of surgical care, particularly in pain management.

Once-Abundant Ash Tree and Antelope Species Face Extinction – IUCN Red List

North America’s most widespread and valuable ash tree species are on the brink of extinction due to an invasive beetle decimating their populations, while the loss of wilderness areas and poaching are contributing to the declining numbers of five African antelope species, according to the latest update of The IUCN Red List of Threatened Species™

NASA's One-Year Mission Investigates How Space Affects Astronauts' Functional Performance

Adapting to the microgravity environment of space changes the way your brain interprets sensory signals, decreases muscle strength and alters cardiovascular function. Astronauts will need to overcome these changes to perform critical mission tasks on a journey to Mars. Simple tasks on Earth such as exiting a vehicle becomes more crucial when stepping foot in an unfamiliar world. Maintaining balance control will be key to a successful mission.

No shortage of hard work

From hand milking with a metal pail and wooden stool to tie-stall and parlour systems, the methods dairy farmers have used to milk their cows has certainly evolved over the years. While the most recent milking system introduced to the dairy industry may help free up a bit of time for dairy farmers, there is still no shortage of hard work.A number of farmers are now adopting an automatic milking system and with it comes a few questions, especially around the environmental impact of the new system.

Standing too much at work can double your risk of heart disease

There's been a lot of interest in the harmful effects of prolonged sitting at work, from academics and the public alike. The attention being paid to sitting – or rather, not sitting – while on the job stems from the scientifically validated message that being sedentary in general, both indoors and outdoors, is bad for your health.However, comparatively little attention has been devoted to the harmful effects of prolonged standing at work, despite past studies linking it to chronic back pain and musculoskeletal disorders (MSDs) in the lower limbs.
