Yale Journal: How, When, and Why Industrial Ecology is Good for Business
Industrial ecology, a rapidly growing field focused on sustainable production and consumption, has contributed numerous important tools to modern environmental management - life cycle assessment; "industrial symbiosis," or the by-product exchange between neighboring facilities; "design for environment"; and the use of material flow analysis to track resource use in supply chains, companies, and economies.
Fly genome could help us improve health and our environment
The house fly might be a worldwide pest, but its genome will provide information that could improve our lives. From insights into pathogen immunity, to pest control and decomposing waste, the 691 Mb genome has been sequenced and analyzed by a global consortium of scientists, and is published in the open access journal Genome Biology.
Adenosine can melt 'love handles'
The number of overweight persons is greatly increasing worldwide - and as a result is the risk of suffering a heart attack, stroke, diabetes or Alzheimer's disease.
Moderate Levels of 'Free Radicals' Found Beneficial to Healing Wounds
Long assumed to be destructive to tissues and cells, "free radicals" generated by the cell's mitochondria-the energy producing structures in the cell-are actually beneficial to healing wounds.

New Univeristy of Virginia study upends current theories of how mitochondria began
Parasitic bacteria were the first cousins of the mitochondria that power cells in animals and plants - and first acted as energy parasites in those cells before becoming beneficial, according to a new University of Virginia study that used next-generation DNA sequencing technologies to decode the genomes of 18 bacteria that are close relatives of mitochondria.
Presence of enzyme may worsen effects of spinal cord injury and impair long-term recovery
Traumatic spinal cord injury (SCI) is a devastating condition with few treatment options. Studies show that damage to the barrier separating blood from the spinal cord can contribute to the neurologic deficits that arise secondary to the initial trauma.
Immune cells in the liver drive fatty liver disease and liver cancer
Immune cells that migrate to the liver and interact there with liver tissue cells get activated by metabolic stress (e.g. through lipids of a high fat diet) and drive the development of fatty liver disease, non-alcoholic steatohepatitis and liver cancer.
New pill-only regimens cure patients with hardest-to-treat hepatitis C infection
Two new pill-only regimens that rapidly cure most patients with genotype 1 hepatitis C (HCV) infection could soon be widely prescribed across Europe.
A global natural gas boom alone won't slow climate change
A new analysis of global energy use, economics and the climate shows that without new climate policies, expanding the current bounty of inexpensive natural gas alone would not slow the growth of global greenhouse gas emissions worldwide over the long term, according to a study appearing today in Nature.

Researchers at the University of Calgary's Hotchkiss Brain Institute (HBI) and Southern Alberta Cancer Research Institute (SACRI) have made a discovery that could prolong the life of people living with glioblastoma - the most aggressive type of brain cancer.
Study shows inpatient palliative care reduces hospital costs and readmissions
Palliative care provided in the hospital offers known clinical benefits, and a new study shows that inpatient palliative care can also significantly lower the cost of hospitalization and the rate of readmissions.
High-fat meals could be more harmful to males than females, according to new obesity research
Male and female brains are not equal when it comes to the biological response to a high-fat diet. Cedars-Sinai Diabetes and Obesity Research Institute scientist Deborah Clegg, PhD, and a team of international investigators found that the brains of male laboratory mice exposed to the same high-fat diet as their female counterparts developed brain inflammation and heart disease that were not seen in the females.
