Science on Google+

Explore. Discover. Learn.

The primary goal of this page/database is to make it easier for people to connect with scientists, science journalists, science teachers (K-12), and science pages on Google+.  

How do I use this database to follow science on Google+?
You can search for and follow scientists, science writers, science teachers, and science pages in two ways. First, the database is categorized by discipline. You can click on the links at the top of the spreadsheet or the tabs at the bottom of the spreadsheet to search within a discipline. You can circle individual profiles/pages by clicking on the Google+ links. Or second, you can add discipline specific shared circles. We will publish updated shared circles at regular intervals for your convenience.

About 7 weeks ago Do You Have a Science Question for our Community?

One of our members +Miz Abynaah wanted to know more about the Doppler Effect ( +Mike Aben  wrote this terrific explanation below as well as sharing this great video by +Alt Shift X.

Mike Aben: The Doppler Effect
The Doppler effect occurs whenever an object emitting waves is moving.  The effect is observed with any waves (water, sound, light, etc).  The waves being emitted ahead of the object's motion are compressed, which means they will reach an observer at a higher frequency than if the object was stationary.  The waves emitted behind the object are stretched out and will reach an observer at a lower frequency.

With sound waves, this affects the pitch of the sound heard.  For example, the sound of a car traveling towards you will be at a higher pitch than the sound of a car moving away from you.  With visible light, it is the colour of the light that is affected.  Lower frequency light is redder
About 6 weeks ago Casual Night with Arachnids
In two days +Science on Google+ will be streaming “Casual Night with Arachnids”. The Hangout On Air will consist of a series of short presentations from spider experts (see for event post), and we are inviting all of you to watch the live event.There will be several minutes after each talk to answer questions. Please feel free to use the Q & A app or event post to ask questions. Questions can also be submitted to @spiderprofessor on twitter. Please use the hashtag  #arachnids14 . You can also watch the archived event on our youtube channel ( Subscribe to the page if you want to keep up on our HOAs.

In preparation for the event, we are sharing this GIF of an Ogre-faced spider (Deinopis subrufa), which is casting a net on a cricket. You can learn more about these net-casting spiders here ( and here's a short video showing an Ogre-faced spider weaving a net and using the net to catch prey...
About 10 weeks ago Scientifically correct "Art"

People usually complain that scientists often use rather boring way of showing their results, you know, lines and graphs and sort. But sometimes we also become a little artistic and play around with colours and other stuff to satisfy both our colleagues and general public (hopefully!).

Below is an artistic "star" which is a result of several months of number crunching on a pretty bad-ass supercomputer. The colours on this handsome star represent the velocity, blueish means plasma is coming towards you and orangish means it is going away from you. The curved lines coming out are magnetic field lines. 

We ran this simulation in order to explain a rather intriguing mystery. Our sun, even when it is most active, produces rather tiny sunspots (tiny as compared to the sun!). These sunspots produce certain amount of x-rays which we can measure. When scientists looked at other stars they found that other stars have much higher level of

The Science Behind #ScienceMediaHype , or “This it how it works in the real world."

The cartoon linked here sums up pretty neatly a lot of things that are hard about being a scientist. If only science were as neat and pretty as what the press release sites and the newspapers described. In the world of newspapers, a line of research always yields fascinating and unequivocal results and the researchers’ cleverness and insight overcomes long odds to reveal amazing truths. Then, we pull the actual papers and the first thing we say to ourselves is, “Hmm. I wish they’d done this too. The paper would have been stronger.” And we recall ourselves the times we’ve published things that weren’t as done as we wanted them to be because it was time to move on, or because the funding was running out, or because it was time for the student to graduate. 

Often, we’ve run out of time because we’ve run the same analysis 39 times and gotten 39 disparate answers, with no rhyme or reason as to why
About 6 weeks ago Massive Hangovers and the Harmonic Series

This picture shows a stable deck of 52 cards in which the top card overhangs the bottom card by about 1.5 card widths. In theory, it is possible to do even better so that the overhang is almost 2.26 card widths. The reason for this has to do with centres of mass and the harmonic series.

In order to understand where the number 2.26 comes from, it is helpful to keep track of the horizontal displacement of each card. We will measure horizontal distances from an origin at the rightmost edge of the top card, in such a way that each card is 2 units wide. The centre of mass of the top card is then 1 unit to the left of the origin. 

The overhang of a stack of cards is the horizontal distance between the rightmost edge of the top card and the rightmost edge of the bottom card. In a stack of two cards, the way to create the largest overhang is to put the centre of mass of the top card above the rightmost edge of the lower card. The combined cent
About 12 weeks ago What scientists say, and what the public hear

Although originating from 2011, this table is currently making the rounds on Twitter.  It comes from an article written by Richard Summerville of +Scripps Oceanography and Susan Hassol of Climate Communication focusing on 'communicating the science of climate change', and how science communicators aren't really getting their message across.

Actually the points they make are relevant to all science communication - not just for climate change.

The original article is very much worth a read - you can find it here

About 6 days ago Cardenolides and Monarchs

Monarchs require milkweeds in order to thrive, and many know it is because they rely on it and use that toxin as their own. The bright colors of the monarch are an indication to predators that they are unpalatable. Predators take heed allowing monarchs to leisurely fly to their next nectar destination undisturbed, but why?

Cardiac glycosides, known as cardenolides, are steroids characterized by a glycoside bond. There are at least 400 known cardenolides, and can be found in a number of plants including milkweed, foxglove, and oleander. Cardenolides inhibit the Na+,K+-ATPase (sodium pump) in vertebrates. Cardiac function is the key disruption, but the ionic balance of other animal cell types are as well including vascular smooth muscle, neurons, and kidney tubules. In the right dose, cardenolides can help treat heart failure and irregular heart beats. In the wrong dose, it can be fatal. 

One of the key features of cardenolides are the bitter taste. The
About 3 weeks ago Deconstructing Gender in STEM

"Our words can have a huge impact. Isn't it time we told her she's pretty brilliant, too? Encourage her love of science and technology and inspire her to change the world."-- Reshma Saujani, Founder of Girls Who Code

The commercial ends by pointing out that 66 percent of 4th grade girls like science and math, but only 18 percent of college engineering majors are female. Society determines gender roles, not biology. But society, according to B. F. Skinner’s Social Learning Theory, plays a huge role in determining behavior. Children begin to “do gender” at a very young age; by five years old, they have a clear concept of not only masculinity and femininity, but also which category they fit into. This binary system is incredibly limiting.
