Outdoor air pollution has long been linked to major health conditions such as heart disease, stroke, cancer, asthma and chronic obstructive pulmonary disease. A new study now adds kidney disease to the list, according to researchers at Washington University School of Medicine in St. Louis and the Veterans Affairs (VA) St. Louis Health Care System.

Pollution may increase the risk of chronic kidney disease and, ultimately, contribute to kidney failure, according to the researchers.

From self-folding robots, to robotic endoscopes, to better methods for computer vision and object detection, researchers at the University of California San Diego have a wide range of papers and workshop presentations at the International Conference on Intelligent Robots and Systems (or IROS) which takes place from Sept. 24 to 28 in Vancouver, Canada. UC San Diego researchers also are organizing workshops on a range of themes during the event.

TALLAHASSEE, Fla. -- For years, scientists and physicians have been debating whether personality and behavior changes might appear prior to the onset of Alzheimer's disease and related dementias.

Now, the findings of a new and comprehensive study from FSU College of Medicine Associate Professor Antonio Terracciano and colleagues, published today in the journal JAMA Psychiatry, has found no evidence to support the idea that personality changes begin before the clinical onset of mild cognitive impairment (MCI) or dementia.

Don't let their appearance fool you: Thimble-sized, dappled in cheerful colors and squishy, poison frogs in fact harbor some of the most potent neurotoxins we know. With a new paper published in the journal Science, scientists are a step closer to resolving a related head-scratcher -- how do these frogs keep from poisoning themselves? And the answer has potential consequences for the fight against pain and addiction.

WASHINGTON -- A new imaging technique makes it possible to precisely digitize clear objects and their surroundings, an achievement that has eluded current state-of-the-art 3D rendering methods. The ability to create detailed, 3D digital versions of real-world objects and scenes can be useful for movie production, creating virtual reality experiences, improving design or quality assurance in the production of clear products and even for preserving rare or culturally significant objects.

Intricate human physiological features such as the immune system require exquisite formation and timing to develop properly. Genetic elements must be activated at just the right moment, across vast distances of genomic space.

CAMBRIDGE, Mass. -- Sometimes things that are technically defects, such as imperfections in a material's crystal lattice, can actually produce changes in properties that open up new kinds of useful applications. New research from a team at MIT shows that such imperfections in a family of materials known as insulating metal oxides may be key to their performance for a variety of high-tech applications, such as nonvolatile memory chips and energy conversion technologies.

Novel lithium electrodes coated with indium could be the basis for more powerful, longer-lasting, rechargeable batteries. The coating hinders undesirable side-reactions between the electrode and electrolyte, provide a more uniform deposition of lithium when charging, and augments storage in the lithium anode via alloying reactions between lithium and indium, as reported by American scientists in the journal Angewandte Chemie. Their success stems from the good diffusion of lithium ions along the interfacial layer.

A partnership between QUT, the NSW Government and farmers could lead to the eventual eradication of the highly invasive African lovegrass threatening pastures and native grasslands Australia-wide.

What they discovered is that local knowledge is the key to a successful management approach.

Manufactured polymers are ubiquitous in our 21st Century lives. The large molecules - long chains of smaller molecules bonded together, form any synthetic clothing you might be wearing, rubbers and glues, and anything made of plastic.
