Montmorency tart cherry juice lowered blood uric acid levels and a marker for inflammation
Tart cherries have long been researched for their association with pain relief -- from gout and arthritis pain to exercise-related muscle pain. A new study published in the Journal of Functional Foods reported consumption of Montmorency tart cherries caused changes in uric acid metabolism, which can have an impact on joint pain. The study also detected increases in specific anthocyanin compounds in the bloodstream after consuming tart cherries.

New molecule fights oxidative stress; May lead to therapies for cancer and Alzheimer's
Breathing oxygen helps the body create energy for its cells. As a result of the breathing process, reactive molecules called 'free radicals' are produced that often cause damage to proteins and genes found in cells. This damage is known as oxidative stress. Free radicals also have been linked to cancer, Alzheimer's and Parkinson's disease. Now, investigators at the University of Missouri have discovered a molecule that treats oxidative stress.

Spiders: Survival of the fittest group
Theorists have long debated the existence and power of a type of evolution called group selection. Now, studying social spiders, two scientists have uncovered the first-ever experimental evidence of group selection driving collective traits in wild populations of these spiders.

Fibromyalgia and the role of brain connectivity in pain inhibition
The cause of fibromyalgia, a chronic pain syndrome is not known. However, the results of a new study that compares brain activity in individuals with and without fibromyalgia indicate that decreased connectivity between pain-related and sensorimotor brain areas could contribute to deficient pain regulation in fibromyalgia, according to an article published in Brain Connectivity.

New study provides key to identifying spiders in international cargo
Spiders found in international cargo brought into North America are sometimes misidentified, which can lead to costly and unwarranted eradication measures. A new study provides a key to identifying spiders commonly found in international cargo.

Proving 'group selection'
The notion of 'group selection' -- that members of social species exhibit individual behavioral traits that render a population more or less fit for survival—has been bandied about in evolutionary biology since Darwin. The essence of the argument against the theory is that it's a 'fuzzy' concept without the precision of gene-based selection.

UMN research pinpoints microRNA tied to colon cancer tumor growth
Researchers at the University of Minnesota have identified microRNAs that may cause colon polyps from turning cancerous. The finding could help physicians provide more specialized, and earlier, treatment before colon cancer develops. The findings are published today in The Journal of Pathology.

CEC releases its first-ever multi-year examination of reported industrial pollution in North America
The Commission for Environmental Cooperation (CEC) has released a comprehensive report on the changing face of industrial pollution in North America, covering the years 2005 through 2010. This is the first time an edition of the CEC's Taking Stock series, which gathers data from pollutant release and transfer registers in Canada, Mexico and the United States, has analyzed North American pollutant information over an extended time frame.

A new target for controlling inflammation? Long non-coding RNAs fine-tune the immune system
Regulation of the human immune system's response to infection involves an elaborate network of complex signaling pathways that turn on and off multiple genes. The emerging importance of long noncoding RNAs and their ability to promote, fine-tune, and restrain the body's inflammatory response by regulating gene expression is described in a Review article in Journal of Interferon & Cytokine Research.

New approach can predict impact of climate change on species that can't get out of the way
When scientists talk about the consequences of climate change, it can mean more than how we human beings will be impacted by higher temperatures, rising seas and serious storms. Plants and trees are also feeling the change, but they can't move out of the way. Researchers have developed a new tool to overcome a major challenge of predicting how organisms may respond to climate change.

Neural activity predicts the timing of spontaneous decisions
Researchers have discovered a new type of brain activity that underlies the timing of voluntary actions, allowing them to forecast when a spontaneous decision will occur more than a second in advance. 'Experiments like this have been used to argue that free will is an illusion, but we think that this interpretation is mistaken,' says Zachary Mainen, a neuroscientist at the Champalimaud Centre for the Unknown, in Lisbon, Portugal, who led the research, published on Sept. 28, 2014, in the journal Nature Neuroscience.

Research confirms controversial Darwin theory of 'jump dispersal'
More than one hundred and fifty years ago, Charles Darwin hypothesized that species could cross oceans and other vast distances on vegetation rafts, icebergs, or in the case of plant seeds, in the plumage of birds. Though many were skeptical of Darwin's 'jump dispersal' idea, a new study suggests that Darwin might have been correct.

'Stealth' nanoparticles could improve cancer vaccines
Cancer vaccines have recently emerged as a promising approach for killing tumor cells before they spread. But so far, most clinical candidates haven't worked that well. Now, scientists have developed a new way to deliver vaccines that successfully stifled tumor growth when tested in laboratory mice. And the key, they report in the journal ACS Nano, is in the vaccine's unique stealthy nanoparticles.

Deconstruction of avant-garde cuisine could lead to even more fanciful dishes
One of the most iconic forms of avant-garde cuisine, also known as molecular gastronomy, involves the presentation of flavorful, edible liquids -- like cocktails or olive oil -- packaged into spheres. Now a team of scientists, in collaboration with world-renowned chef Ferran Adriá, is getting to the bottom of what makes these delectable morsels possible. Their findings appear in ACS' The Journal of Physical Chemistry B.

Dog waste contaminates our waterways: A new test could reveal how big the problem is
Americans love their dogs, but they don't always love to pick up after them. And that's a problem. Dog feces left on the ground wash into waterways, sometimes carrying bacteria -- including antibiotic-resistant strains -- that can make people sick. Now scientists have developed a new genetic test to figure out how much dogs are contributing to this health concern, according to a report in the ACS journal Environmental Science & Technology.

Laying siege to beta-amyloid, the key protein in Alzheimer's disease
This is the first time that a method allows scientists to monitor aggregation while simultaneously detect a structural pattern responsible for the toxicity of beta-amyloid aggregation. The researchers state that these studies are a step towards finding a therapeutic target for a disease which, to date, has no treatment.

Eighty percent of bowel cancers halted with existing medicines
An international team of scientists has shown that more than 80 percent of bowel cancers could be treated with existing drugs. The study found that medicines called 'JAK inhibitors' halted tumor growth in bowel cancers with a genetic mutation that is present in more than 80 per cent of bowel cancers. Multiple JAK inhibitors are currently used, or are in clinical trials, for diseases including rheumatoid arthritis, psoriasis, blood cancers and myeloproliferative disorders.
