WorldWideScience Patent Searching - Library Guide at Wichita State University Wichita State University's Ablah Library is one of 84 U.S. Patent and Trademark Research Centers (PTRCs) in the country and the only PTRC in Kansas. Since receiving this designation in 1991, we have received copies of U.S. patents and a variety of patent and trademark searching tools in both print and electronic formats, as well as extensive training in providing patent and trademark research assistance. The Library is open to the public, and we assist with preliminary patent and trademark research by appointment at no charge. Our collections of U.S. government publications include complete U.S. patents -- on microfilm, optical disks and the Internet -- from 1790 to the present, and all federal trademarks that are registered or pending. Our collections contain additional indexes and finding aids for both patents and trademarks. Our Services Location For patent and trademark information, visit or contact Ablah Library at WSU during University Libraries Hours.

Pluto’s misbehaving moons Isaac Newton was hardly used to failure. The moon beat him, though. In 1695, Newton attacked what has since become known as the “three-body problem,” trying to predict the moon’s motion using his new universal law of gravitation. He knew that our satellite was influenced by the mass of both the sun and the earth, but after laboring for months to work out a set of equations that could predict lunar positions with even moderate accuracy, “I despaired of compassing ye Moons Theory, & had thoughts of giving it over as a thing impracticable,” he declared. Misbehaving moons are with us still. Continue reading below Even if you knew the current position and all the forces acting on them, no combination of precision observation and rigorous calculation will be able to tell you which side of Hydra or Nix will face Pluto past some defined and very finite amount of time into the future. In the case of Nix and Hydra, the answer is not much. Continue reading it below Isaac Newton wasn’t sure. Related:

OWL Coming Soon: A new look for our same great content! We're working hard this summer on a redesign of the Purdue OWL. Worry not! Our navigation menu and content will remain largely the same.

Galactic perspective The human species is great, but its tendency to claim superiority may be its affliction. View these photos and challenge your perspective. The human race has an affliction of assumed superiority. Apparently with the advent of fire, the Homo erectus brain swelled to a proportion that allowed the capability to learn and develop language, fiddle with technology, and form meaningful relationships with others. What didn’t happen with this ‘so-called’ jump in evolution, however, was the capability to live from a space of compassion, commune with nature, and respect (or easily perceive) the innate force that ties all together. While human beings continue to transcend previous levels of innovation, intellect, and comprehension in self and the ‘Spirit’ of life, as a collective their air of superiority still reins supreme. First, let’s start off with YOU. Credit: Diply At 30,000 feet, this is what you look like: Credit: Flickr / Benjy At 100,000 feet, this is you: Credit: Wikipedia Credit: Gen Beta

Live forever: Scientists say they’ll extend life ‘well beyond 120’ | Science In Palo Alto in the heart of Silicon Valley, hedge fund manager Joon Yun is doing a back-of-the-envelope calculation. According to US social security data, he says, the probability of a 25-year-old dying before their 26th birthday is 0.1%. If we could keep that risk constant throughout life instead of it rising due to age-related disease, the average person would – statistically speaking – live 1,000 years. Yun finds the prospect tantalising and even believable. Late last year he launched a $1m prize challenging scientists to “hack the code of life” and push human lifespan past its apparent maximum of about 120 years (the longest known/confirmed lifespan was 122 years). Yun believes it is possible to “solve ageing” and get people to live, healthily, more or less indefinitely. Yun’s quest – a modern version of the age old dream of tapping the fountain of youth – is emblematic of the current enthusiasm to disrupt death sweeping Silicon Valley.

Online Materials Information Resource - MatWeb Might Alien Life Evolve Like the Incredible Octopus? by Natalie Shoemaker Consider the octopus: a creepy skeleton-less creature with limbs that have regenerative properties and a mind of their own. Its structure — inside and out — makes it like no other animal on earth. As a part of the Mollusca phylum, the octopus seems so far removed from its clam cousin. “Very simple molluscs like the clam — they just sit in the mud, filtering food. Scientists have marveled at the octopus for years, and now they've taken the time to delve deeper into its biology by decoding its genome. "The octopus appears so utterly different from all other animals, even ones it's related to, that the British zoologist Martin Wells famously called it an alien. Researchers from the University of Chicago; the University of California, Berkeley; the University of Heidelberg in Germany; and the Okinawa Institute of Science and Technology in Japan came together in this genome-wide analysis.

what-if-carbon-dioxide-was-pink Written by Gregg Kleiner. Here’s one dads desperate attempt to slow climate change by thinking pink… As a father, I often lie awake nights tossing and twisting with worry about the climate crisis and how it will impact the lives of my children, their children, children all over the world. As a writer, my imagination fires easily, in full color, so I can easily envision the worst. I blink in the dark and see rising seas, mountains with no snow, super storms swirling on the horizons. On one of those sleep-deprived nights, I got to thinking about how I might use my gift for writing stories to help kids better understand climate change, and then take action. I talked to Green Diva Meg about it in a recent Green Divas Green Dude episode… It’s become very clear that we can’t wait for our politicians to ride in and slow climate change. So we can’t wait for our leaders to come around. But what if we could see carbon dioxide? Puffing from smoke stacks and tail pipes and the butts of cows? Bonus:

PLoS: Publication List The range of PLOS titles is expanding and now includes a number of new websites. Below, we describe the role of each group of products and how they fit together to support our mission of leading a transformation in research communication. Original Content These titles vary in the speed of publication, the nature of the peer review and selection process that takes place ahead of publication, and the breadth and nature of content that is published. They include: The PLOS Suite of Journals: - PLOS Biology - PLOS Medicine - PLOS Genetics - PLOS Computational Biology - PLOS Pathogens - PLOS Neglected Tropical Diseases PLOS Currents PLOS Blogs Organization of Content We are also exploring new ways to organize content after publication with PLOS Collections.
