My specialty is neuroscience and physiology, but I love all sciences, athletics, healthy food and fun people.

I love interaction and scientific dicussion. Never be afraid to ask me questions. I may not have the answer, but I'll be damned if I haven't learned how to do a good, quick Google Scholar search to find out.

In addition I like to look at non-science related cute animal pictures, art and funny comics too :)

Hope you enjoy my blog but please, feel free to leave suggestions for improvement!

USING LIVING FISH TO STUDY ANCIENT EVOLUTIONARY CHANGES: How plasticity works in evolution race

Ambitious experimental and morphological studies of a modern fish show how developmental flexibility may have helped early ‘fishapods’ to make the transition from finned aquatic animals to tetrapods that walk on land.

The origin of tetrapods from their fish antecedents, approximately 400 million years ago, was coupled with the origin of terrestrial locomotion and the evolution of supporting limbs. Polypterus is a ray-finned fish (actinopterygians) and is pretty similar to elpistostegid fishes, which are stem tetrapods.

Polypterus therefore serves as an extant analogue of stem tetrapods, allowing us to examine how developmental plasticity affects the ‘terrestrialization’ of fish. How else would you find out what behavioral and physiological changes might have taken place when fish first made the move from sea to land over 400 million years ago? putting a fish walking on land…

Domestic violence and abuse can happen to anyone, but the vast majority of victims are young girls and women simply because they are “the weaker sex”.
Did you know:
On average, 2 women a week are killed by a current or former male partner. This constitutes nearly 40% of all female homicide victims.
45% of women are abused/raped by current husbands or partners, 9% by former partners, and a further 29% of perpetrators were otherwise known to the victim. Only 17% are attacked by by strangers.
44% of victims of domestic violence are involved in more than one incident. A large number of women experience the same abuse every week.
On average, a woman is assaulted 35 times before her first call to the police.
30% of domestic violence either starts or will intensify during pregnancy.
In almost 75% of incidents, a child is present or in a room closeby.
THIS HAS GOT TO STOP. IT DOESN’T HAVE TO BE THIS WAY.
It’s time to show the world that we are not weak and we will simply not stand for this kind of ill treatment. Women should be treated as princesses, like Ariel and Cinderella, who never have to live in fear of their so-called Prince Charming.
It’s time to stand up. To speak out. To be heard.

I love science, and it pains me to think that so many are terrified of the subject or feel that choosing science means you cannot also choose compassion, or the arts, or be awed by nature. Science is not meant to cure us of mystery, but to reinvent and reinvigorate it.

"Blood and Gold"



"One of the biggest hopes for nanotechnology is the design of molecules to support living processes. Pictured here, tiny gold ‘nanorods’ cover the surface of red blood cells – a snapshot of biotechnology in action, fixed in time with a blue chemical agent. Each gold nanorod holds tiny ‘pockets’, called aptamers, filled with a blood thinning chemical called thrombin. Firing a laser at these harmless specks of gold causes them to melt just enough to release the thrombin, preventing blood from clotting. The process can be reversed by triggering the release of a different chemical which counteracts the thrombin, allowing the blood to clot naturally. Intravenous injections of chemicals like heparin are currently used all over the world to prevent dangerous blood clots after operations. In the future, nanotechnology could be used instead, with the advantage of controllable clotting at the flick of a laser switch.”Written by John AnkersImage by Helena de PuigMassachusetts Institute of Technology, USAOriginally published under a Creative Commons Licence (BY 4.0)Research published in PLOS One, July 2014http://dx.doi.org/10.1371/journal.pone.0068511Originally published on http://www.bpod.mrc.ac.uk/archive/2014/8/29

thepweproject said: Hi, my name is Freya and I have epilepsy. I am doing a project for my fine art course at uni, which revolves around identity in the modern world and how we can use social media to create a community. When I was diagnosed I had no sense of identity and felt very alone with my condition. I would be incredibly grateful if you could lead people to my project which aims to help people with epilepsy come to terms with their condition. Thank you, Freya.

Hi Freya,

Absolutely. I think educating people is the first step towards change in cultural attitudes and fostering a safe place for discussions like yours.

Friends and fans, please take a moment to check out Freya’s project.

Thank you,

Yesterday we discussed some of the basic mechanics of a frisbee in flight. Although frisbees do generate lift similarly to a wing, they do have some unique features. You’ve probably noticed, for example, that the top surface of a frisbee has several raised concentric rings. These are not simply decoration! Instead the rings disrupt airflow at the surface of the frisbee. This actually creates a narrow region of separated flow, visible in region B on the left oil-flow image. Airflow reattaches to the frisbee in the image after the second black arc, and the boundary layer along region C remains turbulent and attached for the remaining length of the frisbee. Keeping the boundary layer attached over the top surface ensures low pressure so that the disk has plenty of lift and remains aerodynamically stable in flight. A smooth frisbee would be much harder to throw accurately because its flight would be very sensitive to angle of attack and likely to stall. (Image credits: J. Potts and W. Crowther; recommended papers by: V. Morrison and R. Lorentz)

For the MS3s, MS4s, and interns out there. If you haven’t discovered this website, you are sorely missing out. These videos are perfect on days where you just can’t muster enough energy to do some reading on your own. Not only are the videos great at summarizing a shit ton of clinical information, but they’re FREE.

Disclaimer: These videos were a large part of my prep for my last rotation. I blew through all of the Ob and Gyn lectures and drew out all of Dr. Williams’ awesome treatment flow charts for the shelf. Though I really liked the videos, it’s still yet to be seen how much (or if) they helped me for the shelf. Will update later.

A gut microbe that stops food allergies

A class of bacteria commonly found in the guts of people—and rodents—appears to keep mice safe from food allergies, a study suggests. 
The same bacteria are among those reduced by antibiotic use in early childhood. The research fits neatly into an emerging paradigm that helps explain a recent alarming increase in food allergies and other conditions, such as obesity and autoimmune disease, and hints at strategies to reverse the trend.
Food allergies have increased about 50% in children since 1997. There are various theories explaining why. One is that the 21st century lifestyle, which includes a diet very different from our ancestors’, lots of antibiotic use, and even a rise in cesarean section deliveries, has profoundly changed the makeup of microbes in the gut of many people in developed countries. For example, the average child in the United States has taken three courses of antibiotics by the time he or she is 2 years old, says Martin Blaser, an infectious disease specialist and microbiologist at New York University in New York City. (See here for more on the reach of microbiome research these days.)
Cathryn Nagler, an immunologist at the University of Chicago in Illinois, has spent years probing links between the immune system, intestinal bacteria, and the onset of allergies. Back in 2004, she and her colleagues reported that wiping out gut bacteria in mice led to food allergies. Since then, Nagler has continued trying to understand which bacteria offer allergy protection and how they accomplish that.
In one of the latest efforts, Nagler’s team first confirmed that mice given antibiotics early in life were far more susceptible to peanut sensitization, a model of human peanut allergy. Then, they introduced a solution containing Clostridia, a common class of bacteria that’s naturally found in the mammalian gut, into the rodents’ mouths and stomachs. The animals’ food allergen sensitization disappeared, the team reports online today in the Proceedings of the National Academy of Sciences. When the scientists instead introduced another common kind of healthy bacteria, called Bacteroides, into similarly allergy-prone mice, they didn’t see the same effect. Studying the rodents more carefully, the researchers determined that Clostridia were having a surprising effect on the mouse gut: Acting through certain immune cells, the bacteria helped keep peanut proteins that can cause allergic reactions out of the bloodstream. “The bacteria are maintaining the integrity of the [intestinal] barrier,” Nagler says.
The research “opens up new territory,” Blaser says. It “extends the frontier of how the microbiome is involved” in immune responses and the roles played by specific bacteria. (Blaser’s group reported earlier this month in Cell that giving mice penicillin soon after birth changed their gut microbiome and made them much more likely to be obese as adults.) Nagler and her university have filed for a patent application on the new findings. The ultimate goal is to “interrupt [the allergy] process by manipulating the microbiota,” she says—a probiotic consisting of Clostridia could be a new allergy therapy, for example. Nagler knows of none on the market yet, and they would need testing in people before becoming a treatment of choice.
