Go home winter, you are wasted
15 April 2014. I paid my taxes, Oldman Winter, now leave me alone. I hope my bulbs survive the next couple of days. It was 28°F this morning. It's supposed to be 50°F on Thursday.

Schlieren Flow Visualization, let the science flow
Many thanks to +Koen De Paus for sharing this. I learned something new today. I had not heard of Schlieren flow visualization before.

Casting Light on Sound to See its Shadow

"When light passes between areas of different air density, it bends. You've probably noticed the way distant pavement seems to shimmer on a hot day, or the way stars appear to twinkle. You're seeing light that has been distorted as it passes through varying air densities, which are in turn created by varying temperatures and pressures.

In the mid-19th century, German physicist August Toepler invented a photography technique called Schlieren Flow Visualization to visually capture these changes in density. The setup is a bit hard to explain in words (watch the video above for a full explanation) but it allows scientists and engineers to see things that are normally invisible: the rising heat from a candle, the turbulence around an airplane wing, the plume of a sneeze.

It can also be used to see sound. Sound, after all, is just another change in air density — a traveling compression wave. A speaker pushes on the surrounding air, creating a wave that travels outward until it encounters the ear drum."

Happy Songkran 2014
I'm so busy that I totally forgot Songkran starts tomorrow. Excuse me for just re-sharing last year's post.

Happy Songkran 2013 or สงกรานต์ 2556
April 13 is Thai New Year. The New Year is 2556, based on the Buddhist Era which starts from the death of Buddha in 545 BC. The pictures are from a visit to Thailand in 2005.

Taking a bite out of poachers
Dogs can do many things to help humans and their fellow animals. I've posted about dogs helping conservatories in Africa before.
I'm not cheetah-ing one #Caturday by posting this dog video

The story below is the first time multi-purpose dogs (tracking, searching, and attacking) have been used for anti-poaching. The dogs are trained to be friendly to visitors of the conservatory. When in attack mode, they are trained to handle varying terrain and obstacles. They seek out carcasses and more importantly, track the poachers from there. They have night vision cameras mounted to aid their human counterparts. More importantly, they are outfitted with the latest in canine armor. You can read more at Public Radio International. via PRI

You can read more about canine armor here: via +Fast Company

Images are from those two links.

If you are interested in donating to have US Police dogs get the canine armor they deserve, you can check out the story of Kilo. He was shot in the line of duty and likely survived due to his canine armor.

Happy #FidoFriday

23 in a row
Congratulations #DetroitRedWings  for making the playoffs for the 23rd straight season. Hopefully we can stay healthy and the kids can keep scoring.
Thanks to their "next man up" philosophy, the Detroit Red Wings are back in the Stanley Cup Playoffs for the 23rd straight season.

Coaches seem to go first -- that seems to be the general rule.  As to Ovie?  That would be a major hit to team quality, so I doubt any imminent departure is in the works.

Alzheimer’s Disease Research
h/t +Letha McGarity for triggering this lazy #ScienceSunday  post about Alzheimer’s Disease (AD). Many of you may have heard of amyloid plaques and how patients with AD have brains riddled with amyloid plaques. In fact, Auguste Deter pictured below, was the first AD patient and her brain was riddled with what we now know are amyloid plaques.

However, I'm going to do a lazy post and direct you to a series of videos here:
Full disclosure, I collaborate with Dr. Klein. However, he really is a great scientist and a great guy. In the videos he'll explain how the hippocampus plays a role and how oligomers are the real story.

We still have a long way to go
Professor +Rajini Rao is a tremendous role model along with Dr. Anandabi Joshee, Dr. Kei Okami, and Dr. Tabat M. Islambooly. If you don't have Rajini circled, you are missing a lot.

Rajini's post is very timely as I've been meaning to re-share +Giselle Minoli's post:
Open letter to men on G+

I think it's best to visit the OP because the discussion is excellent and has many points that, unfortunately, don't follow the re-share.

I think Dr.s Joshee, Okami, and Islambooly would be disappointed to find that, female physicians (after correcting for differences in specialties) make about $12,000 less than their male counterparts. As I said, we still have a ways to go.

Gender Differences in the Salaries of Physician Researchers posted by +Adrienne Roehrich

While searching for the above reference for the discussion in Giselle's post, I stumbled onto this.

Hiring bias via +Mark Brandt

Even in science, we have work to do. The study from PNAS reports that men and women scientist are biased towards hiring men and paying them more.

What can we do? For me, I strongly support programs that foster women in STEM such as +Girlstart. I support equality at work and online. I support +STEM Women on G+. Do you have other suggestions?

I'm pleased that G+ is, in general, very supportive of women in science and I have the pleasure of working with +Rajini Rao +Allison Sekuler +Buddhini Samarasinghe +Carissa Braun and +Aubrey Francisco on +ScienceSunday 
On The Shoulders of Giants

♀ A sepia print of an Indian woman, a Japanese woman and a woman from Syria, dated 1885. What do they have in common? Extraordinarily, each was the first licensed female medical doctor in their country of origin. They were trained at the Women's Medical College in Pennsylvania, the first of its kind in the country. This was a time before women had the right to vote. If they did attend college at all, it was at the risk of contracting "neuralgia, uterine disease, hysteria, and other derangements of the nervous system” (according to Harvard gynecologist Edward H. Clarke). 

An all-woman medical school was first proposed in 1846, supported by the Quakers and the feminist movement. Dr. Ellwood Harvey, one of the early teaching faculty, daringly smuggled out a slave, Ann Maria Weems, dressed as a male buggy driver, from right outside the White House. With his reward money, he bought his students a  papier maché dissection mannequin. Eventually, poverty forced him to quit teaching, but he still helped out with odd jobs. What a magnificent man!  

Fate and fortune were to buffet Ms. Joshi's life. Married at age 9 to a man 11 years older, her husband turned out to be surprisingly progressive. After she lost her first child at age 14, she vowed to render to her "poor suffering country women the true medical aid they so sadly stand in need of and which they would rather die than accept at the hands of a male physician". She was first offered a scholarship by a missionary on condition that she converted to Christianity. When she demurred, a wealthy socialite from New Jersey stepped in and financed her education. She is believed to be the first Hindu woman to set foot on American soil. I didn't arrive until 1983 ;)

Times were tough then. The fate of these three intrepid pioneers was a sad one. Joshi died of tuberculosis in India at the age of 21, without ever practicing. Fittingly, her husband sent her ashes back to America. Islambouli was not heard of again, likely because she was never allowed to practice in her home country. Although Okami rose to the position of head of gynecology at a Tokyo hospital, she resigned two years later when the Emperor of Japan refused to meet her because she was a woman. 

Times have changed. My own mother was married at the age of 13 to a man also 11 years her senior. My father recalls helping my mother with her geography homework in high school. She never did attend college, despite being a charismatic woman with quicksilver wit and efficiency. Little wonder then, when I was accepted into graduate school in the US, unmarried and 21 years young, my parents staunchly stood behind me against the dire predictions of friends and relatives ("She'll come back with a yellow haired American!" "Haven't you read Cosmopolitan magazine? They are all perverts there!"). Happily, I escaped perversion, earned my doctoral degree and even gained a supportive spouse of my own. In 2004, I became only the 103rd woman to be promoted to Professor in the 111-year history of the Johns Hopkins medical school, and the first in my department, the oldest Physiology department in the country. If I have seen further it is by standing on the shoulders of giants

Finally Spring
The snowdrops, Galanthus (Snowdrop; Greek gála "milk", ánthos "flower"), really put on a show this year. I guess they liked all the snow piled on the during this ridiculous winter. The crocus are just starting to come out as well.

I take it both ways
How about you? Black or with sugar. Joking aside, I normally drink plain Chinese teas. I make Chai sometimes. For English black teas and Earl Gray, I add sugar most of the time. Sometimes I add milk. Vote on +Ryan Prince 's post. This is very important.
I think I've probably lost this anyway, but assuming you drink tea, do you take it with or without sugar? +1 the appropriate response below.

Edit: and when I say "tea" I mean proper tea - PG Tips, Tetley, Yorkshire Tea, Typhoo, etc - not your fancy stuff like chai (though I do love chai)
I'm the medical imaging, Red Wings, Formula One, Tech guy.
I'm a scientist/engineer interested in image based biomarkers, i.e., non-invasively visualizing disease or response to therapy. I mainly research cancer using MRI, PET/SPECT/CT, and EPRI but I'm also interested in cardiovascular research.

Sports: Big formula one fan, Detroit Red Wings, Chicago Bears, and Chicago White Sox.

Music: I like pretty much everything except country. Big fan of Pink Floyd. Bob Marley is a god-like-hero. I love house music when I'm programming or doing image analysis. Miles Davis is a mutical genius (say it in Gumby's voice).

Misc: love dogs, science/technology (gadgets), cars, bicycling... Also Member of The Incorrigibles.

My passion is science and science is my career choice, so I am grateful to be a co-curator for #ScienceSunday.

Don't circle me if you are not open minded and interested in science. I'm very much against the anti-intellectualism/anti-science movement.

There is a cult of ignorance in the United States, and there always has been. The strain of anti-intellectualism has been a constant thread winding its way through our political and cultural life, nurtured by the false notion that democracy means that "my ignorance is just as good as your knowledge."
     Isaac Asimov, column in Newsweek (21 January 1980)
