The Nicobar Pigeon is the closest living relative to the dodo. A large, mainly ground-dwelling bird, the Nicobar pigeon is the only member of its genus. Due to a lack of natural predators and isolation on small islands, this species has been able to develop bright plumage.
This species is classified as Near Threatened because throughout its wide range it is thought to be declining as a result of capture for food and the pet trade, habitat destruction and predation by introduced mammals. (Source & Source)
Kids grow up dreaming of becoming Superman, the Black Panther, Wonder Woman or the Green Lantern — mythical superheroes with outlandish outfits and out-of-this-world capabilities. For five days this January at San Francisco’s Pier 9 workshop, six kids were able to do just that. “[Star Wars’ Rey] builds things, and I’m building things.”

Mint is a weird flavour, how can something taste like cold?
Menthol, a chemical found in mint leaves, activates the same ion-channel protein in your nerves as a drop in temperature, causing the same sensation.

Artist suspends real clouds in the middle of the room
That’s not photoshop; that’s an actual cloud hovering inside an actual room. Artist Berndnaut Smilde merges art and science to create small man-made clouds that exist — albeit for just a moment — indoors.
Smilde uses a fog machine to make the actual clouds, but also carefully regulates the humidity and temperature. Even so, these installations exists for a mere moment before dissipating inside the room. If you’re not there in the moment, then you only get to experience these brief scientific sculptures as photographs. (Source)
A fluidic oscillator is a device with no moving parts that sprays a fluid from side to side. The animations above illustrate how they work. A nozzle funnels a fluid jet through a chamber with two feedback channels. When the jet sweeps close to one side of the chamber, part of the fluid is directed along the feedback channel and back toward the inlet. That flow feeds into a recirculating separation bubble in the middle of the chamber. As that bubble grows, it pushes the jet back toward the other feedback channel, continuing the cycle. Many automobiles use fluidic oscillators in their windshield washer sprays. Check out the award-winning full video from the Gallery of Fluid Motion. (Image credit: M. Sieber et al., source)
Nola was born in the southern savanna woodlands of Sudan. In the mid-1970s she was captured to protect her from poachers, and in 1989 she moved to the San Diego Zoo. She shared her enclosure with buffalo, giraffes and gazelles, and enjoyed daily belly scratches.
In 1990, a male rhinoceros named Angalifu joined Nola in San Diego, but she wasn’t interested in him. After hormone treatments, she mated with another male named Saut, but never became pregnant.
Saut died in 2004. Angalifu died last year. Nola was getting older, and suffering from a bacterial infection. Yesterday the zoo announced:
In the last 24 hours, Nola’s condition worsened and we made the difficult decision to euthanize her. We’re absolutely devastated by this loss, but resolved to fight even harder to #EndExtinction.
With the death of Nola this weekend, the northern white rhinoceros inches closer to true extinction. But it became extinct in the wild 2008, and the remaining rhinos have all been to old to breed for several of years. Still, there are plans to resurrect the subspecies using a preserved egg and sperm. The San Diego Zoo’s Institute has pledged $2 million to this difficult project.
And there is reason to be hopeful. A cousin subspecies, the southern white rhino, has seen its population blossom from 20 to 20,000 in the last century thanks to the intervention of humans.

The mask depicted above is hollow. One side is concave the other, convex. However despite how hard we try we can only see two concave faces. This is an optical illusion.
So why does this happen? The brain is said to have specific regions dedicated to processing faces. We know that faces are convex from our experience and knowledge so our brain processes it in a way that makes sense to us and matches our expectations.
This is so strong that it entirely over rides reality even when we are aware that what we are seeing is wrong, it is impossible to stop ourselves from perceiving it as a convex protruding face!
However this optical illusion actually fails to work on those with schizophrenia. This is to do with their unique way of processing information.
I’m pretty sure this is the MOST ADORABLE thing in the Universe today. I’ve tried to find the fabric on Spoonflower, but haven’t gotten lucky yet. I bet Emily could probably use her superpowers to find it in a heartbeat. Stay tuned…
For now, just let this girl’s love of math and science make your day.

How to Take Notes: from a Textbook
(Be sure to change the post type from link to text post when you reblog, if that’s what you want to do)
This method is best suited for textbook or article notes, and is a version of revised notes. It is also well suited for books you plan on returning to the bookstore or books you have rented, as it does not involve writing directly in the book itself.
First, you’ll need to find a notebook, and the pens you like the best. My favorite notebooks to work with for note-taking, especially for my “revised” notes, are the Moleskine, hard or soft cover, in size extra large. For this specific class (Intro to Gender and Women’s Studies), I decided that lined pages would suit my needs better. For my math, engineering, and science classes, I usually opt for squared paper, as I draw in lots of diagrams and graphs.
My favorite pens ever are Staedtler Triplus Fineliners, so even though they show through the pages a little bit, I still choose to use them. I just love the way they write. I usually write out my notes themselves with a Pilot G2 05 with black ink, as it writes with a finer line and doesn’t bleed through quite as much.
I usually try to set up my notebooks about a week or so before class starts, that way it’s ready to go on my first day of class.
You’ll want to start off by setting up your notebook. On my first page, I put my course code for my university, as well as the course title.
Next, and this is perfectly optional (I just like the way it makes the book look, especially at the end of the semester), I include some sort of related quote to the course. For my engineering courses (which are related to my major), I put a different quote at the beginning of each section. But as this is a two-month long course during the summer, I opted for one quote by Mohadesa Najumi at the beginning of my book.
Next I set up my table of contents and include a page with basic course information. As this course is all online, my course information just included the start and end dates of the course, what time content is posted and on what day, and the name of my professor. For my usual courses, I will include the days of the week the class meets on and where, TA names and contact info, as well as posted office hours for my professors and TAs and tutoring hours either in the library or in the College of Engineering.
Next is one of the things I’m most proud of.
While I religiously use my Erin Condren planner to map out my days, weeks, and months, I have found throughout my college experience that including monthly views for the months my class ranges has been helpful. This way, there’s no sifting through the multiple colors I have in my planner, and everything related to that class is in the same notebook.
On this calendar I include start dates of the class, the end date, the dates of exams or quizzes, assignment deadlines, office hours, etc.
For this course, as I just started a few days ago, I don’t have a lot of dates or information, so my calendars are still very empty.
Next up I go to my weekly overview. At the beginning of each week, I set up a weekly layout, and I include a list of assignments, tests, quizzes, tasks, projects, etc that need my attention throughout the week, and I place the days I plan on doing them or the days they need turned in onto the weekly layout.
Now you’re finally ready to get into taking the notes.
Gather your book, some sticky notes, and your favorite pen or pencil.
I color code my stickies so that the “revision” process later goes a bit smoother. In this case, I’m using blue to denote something interesting, intriguing, or thought provoking, greenish-yellow to represent the facts or important concepts, and pink for important vocabulary words and their definitions.
Read the selection once.
As you read along the second time, write notes on your stickies, and place them in a place of relevance directly on the page in the book. Just make sure you don’t cover up anything you need to keep reading.
Now, once you’ve read all the material in questions (you can choose to break it up however you want, but since Chapter 1 was assigned for the week, I’ve elected to break it into chapters), carefully remove your stickies one by one and lay them out on a flat surface. This is when having a separate color for vocab can be helpful, as I sometimes put all of my vocab at the beginning or end of a section, especially if the section of reading was particularly large.
Organize your stickies in an order that makes sense to you, and use this order as your basis for transferring those notes into your notebook. The order you choose can just be lumping them under similar headings. Some classes even lend themselves to a nice chronological order. Whatever you choose, just make sure it’s something that will make sense to you when you come back to it in the end.
Okay so up there I wasn’t following my own advice, I just thought I would include the picture because my handwriting looks nice…
Now organize the stickies!
Now you just start writing everything from the stickies into your notebook. I like to take each category or subgroup and put them in the book on the facing page, then put them back in my textbook as I finish with each post it.
Moving on to the next category.
Before you know it, you’ve written all of your stickies into your notebooks.
Now you’re revved up and ready to go. You can either keep going and make a note summary page (which I’ll show you next week), or you can leave it. These will also be helpful when reviewing for tests and quizzes. You can highlight or underline, or use even more stickies (which is what I usually do) as you review.
Well, that’s all I have for you right now. Happy studying!

The Augmented Reality Sandbox
The Augmented Reality Sandbox (orginally developed by researchers at UC Davis) lets users sculpt mountains, canyons and rivers, then fill them with water or even create erupting volcanoes. This version of the device at UCLA was built by Gary Glesener using off-the-shelf parts and good ol’ playground sand.
Any shape made in the sandbox is detected by an Xbox Kinect sensor and processed with open source software. It is then projected as a color-coded contour map onto the sand.
A Von Kármán vortex street is a repeating pattern of swirling vortices caused by the unsteady separation of flow of a fluid around a rounded obstacle.
