A photobombing squirrel helped a Northland College student document the highest recorded observation of the gray tree frog in northern Wisconsin.
As part of a larger study of old and large white pine canopies, Northland College senior Madison Laughlin of Edmonds, Washington, documented the tree frog almost 70 feet above the ground - more than double the highest previously on record. Her findings were published in the May issue of the scientific journal, Ecology.
"This frog appears to be able to weather sun during the day in the canopy by finding shady and cool spots,"¯said Laughlin, who studies natural resources and geology.
As part of the study, Laughlin and her tree-climbing professors set up three motion sensitive cameras in three white pines to observe life at the tops of the trees. They have already identified 17 species of animals - squirrels, birds, mice, and tree frogs - as well as a mushroom species, a variety of insects and many lichen species particular to this special habitat.
"This is research that is literally being done in our backyard," said Assistant Professor of Natural Resources Erik Olson. "That is one of the beautiful things about science - we don't have to go to the ends of the Earth to make new insights into our world."
In this case, capturing frogs in unexpected places. Tree frogs are small and similar in temperature to their environment so do not set off the motion sensitive cameras. However, flying squirrels do. And on four different occasions, flying squirrels have exposed tree frogs up high.
"It was really exciting to find something that wasn't a squirrel," Laughlin said of looking through hundreds of collected camera captures.
Laughlin says that there is a gap in what we know about tree frogs. "Oddly, there isn't much research on tree frogs in trees. Most of the research is about their breeding, which takes place in ponds," she said. "This research is helping open the door to the vertical dimension of habitat."
These images suggest a higher level of habitat usage in the tops of trees than previously thought. "I love forestry and forest ecology,"¯Laughlin said. "And I've never thought about the three-dimensional aspect of habitat - there's a lot going on up there."
Additional work is underway to describe the habitat usage of other animals high in the trees and to begin to answer the question of why tree frogs go so high.
"We're not surprised that the canopy is an important habitat, but we are surprised how many and what species are up there and how often they visit," said Assistant Professor of Forestry Jonathan Martin who is co-directing the research. "The combination of the scale and growth patterns of these trees as well as the habitat surprises gives me a renewed appreciation for the complex processes occurring high off ground."
Maryam Mirzakhani was an Iranian mathematician and a professor of mathematics at Stanford University. Her research topics include Teichmüller theory, hyperbolic geometry, ergodic theory, and symplectic geometry.
In 2014, Mirzakhani became both the first woman and the first Iranian honored with the Fields Medal, the most prestigious award in mathematics. The award committee cited her work in "the dynamics and geometry of Riemann surfaces and their moduli spaces".
Mirzakhani died from breast cancer on July 14, 2017 at the age of 40.

Association of Indian Physicians of Northern Ohio (AIPNO) was founded in 1983 as a non-profit organization of physicians of Indian origin in Northern Ohio. A 'Yatra' is a holy pilgrimage. For years, Dr Jaya Shah and Ramesh Shah have led an AIPNO Medical Yatra to tend to the needs of the poorest in different areas of India. Many of the people that the team of doctors see and treat have never had any contact with a medical professional.

Cleveland’s first annual celebration of civic technology, data & the doers working to improve our region, Data Days Cle was presented by the The Cleveland Civic Tech + Open Data Collaborative (The Collaborative) at the HIMSS Innovation Center, 4th floor of the Global Center for Health Innovation.
The Collaborative is a joint initiative of five original partner organizations, including the CWRU Center on Urban Poverty and Community Development, Open Cleveland, of Code for America, Hack Cleveland, OpenNeo, the Cleveland City Planning Commission as well as, and more recently, the Cleveland Shapers, of the World Economic Forum’s Global Shapers venture, and the Ward 14 office of Cleveland City Council.
Data Days was spread over 3 days (Thursday-Saturday) under the ehadings: CTRL, ALT and CLE.
Wizard World Comic Con was back in Cleveland the weekend of March 17-19, 2017. There were a lot of celebrities on hand for panels, photos and autographs such as Incredible Hulk Lou Ferrigno, Gene Simmons of KISS, Barry Bostwick from Rocky Horror Picture Show, Hercules Kevin Sorbo, Monkees Mickey Dolenz and Peter Tork, Lt Uhura from Star Trek and more.
There were lots of vendors selling collectibles, original art, comic books, toys, games, clothes, gear, etc. There were gaming sessions and interesting exhibits such as the Sanford and Son truck, Speed Racer, Ghostbuster car, Dalek and TARDIS from TRACE the Doctor and more. As always the costumes of the vendors and attendees were the best part of the event.
The famous Feynman Lectures on Physics is a physics textbook based on some lectures by Richard P. Feynman, a Nobel laureate who has sometimes been called "The Great Explainer". The lectures were given to undergraduate students at the California Institute of Technology (Caltech), during 1961–1963 and have been a favorite for aspiring physicists ever since.
The three volumes of the book focus on mechanics, radiation, and heat, including relativistic effects (Vol 1), electromagnetism and matter (Vol 2) and quantum mechanics (Vol 3).
In case you didn't know (or forgot) in 2013, Caltech in cooperation with The Feynman Lectures Website made the book freely available, on the web.
As the site says, "Now, anyone with internet access and a web browser can enjoy reading a high quality up-to-date copy of Feynman's legendary lectures.
This edition has been designed for ease of reading on devices of any size or shape; text, figures and equations can all be zoomed without degradation.

The Great Lakes GeekI asked lightheartedly on Twitter "Is there something wrong in getting medical advice from a Manga comic book?" because I have found the information in The Manga Guide to Physiology to be more complete and understandable than many medical websites. Of course the book should not replace a medical professional but it does give a very comprehensive look at the workings of the human body.
Each year we like to gather an eclectic group of friends and business associates for a holiday lunch. No, it's not just techies. Media, non-profits, politicians, business, cultural - they were all represented.
The food and atmosphere at Bo Loong at 38th and St. Clair is always terrific and our 70 guests maxed out the party room.

In addition, the Zero includes 802.11 b/g/n Wi-Fi and ethernet networking capabilities. It also has expansion slots and pins to attach other boards and a USB 2.0 host port.
The Michelson–Morley Experiment was conducted in 1887 by physicist Albert A. Michelson of Case School of Applied Science and chemist Edward W. Morley of Western Reserve University.
This experiment proved the non-existence of the luminiferous ether and was later cited as circumstantial evidence in support of special relativity as proposed by Albert Einstein in 1905.
Michelson was professor of physics at the Case School of Applied Science, and Morley was professor of chemistry at Western Reserve University (WRU), which shared a campus with the Case School on the eastern edge of Cleveland. The Michelson-Morley Experiment was performed in several periods of concentrated observations between April and July 1887, in the basement of Adelbert Dormitory of WRU (later renamed Pierce Hall, demolished in 1962).
Michelson became the first American to win a Nobel Prize in science.
