The interwebs have been going crazy the past few days with the recent announcement that scientists have for the first time detected gravitational waves, the ripples in the fabric of space-time that Einstein predicted a century ago. In terms of scientific advancement, to quote Joe Biden, “This is a big fucking deal!” Bigger than the discovery of the subatomic Higgs boson particle (i.e., the god particle), and it has been suggested this discovery is comparable only to “Galileo taking up the telescope and looking at the planets.” – Penn State physics theorist Abhay Ashtekar
Every year modern medicine brings more and more surprises. It really does seem that the limitations of man’s achievements are solely limited to our creative ability to dream what is possible. This week we bring you the bionic eye. As part of an ongoing trial at Oxford’s John Radcliffe Hospital surgeons implanted a micro electric chip into a patients eye restoring part of her sight.
In response to unprofessional behavior by another scientist, a marine science colleague recently stated that they were so used to bad behavior in their area of research that they just accepted it as normal, and that they basically had “Stockholm syndrome”. Sadly this all too common, that unprofessional behavior in some fields and areas is so common (whether it be academic bullying and hazing, plagiarizing and stealing ideas and data, or sexism and harassment see The Dark Side of Academia) that it becomes the accepted norm. This is particularly prevalent in fields that are small and insular.
Stockholm, despite its associated syndrome, is really quite lovely
This week’s FSF is a bit different. Instead of talking about some relatively new discovery or research endeavor, we are going to focus on an old adage, the Theory of Relativity. The Theory of Relativity is one of those concepts that is hugely important but very poorly understood outside of the physics community. Instead of me befuddling this really important concept, I am going to share one of the more concise and readily understandable explanations to Einsteins hugely important Theory.
This kid and his explanation is already blowing up the inter-webs, and he does an amazing job of taking a really complicated concept and making it easily digestible, so I needn’t say anymore. Enjoy!
“The era of the oncolytic virus is… here.” Stephen Russell, Cancer researcher and haematologist at the Mayo Clinic in Rochester, Minnessota
…. and let me be the first to welcome our new virus overlords!
Last week the US Food and Drug Administration (FDA) made a decision that received little fanfare, but has huge implications for modern medicine and how we approach cancer treatment in the US. That decision? The FDA granted their approval for a genetically engineered virus to be used to treat cancer. That virus was the herpesvirus called talimogene laherparepvec, and its use is for the treatment of melanoma lesions in the skin and lymph nodes. This huge decision makes it the first oncolytic virus to receive market approval and could pave the way for more oncolytic viruses to enter the “market.”
Happy Fun Science FRIEDay! After a brief hiatus, due to life, hoping this installment represents the regular…err, semi-regular, occurrence of FSF.
So this hit the interwebs pretty big earlier this week, the first documented reptile to glow. That honor belongs to the Hawksbill a sea turtle, observed first by David Gruber, of City University of New York.
Lets get one thing out of the way before we delve into the glowing version of Crusher (for my finding Nemo aficionados). The sea turtle is not glowing, its fluorescing… there is a difference. In the ocean lots of organisms fluoresce at longer wavelengths (green, yellow, red) in response to shorter wavelengths (UV, blue, violet). It is a typical property of many biological materials and is noticeable if viewed through restrictive long pass filters, as is the case here.
That being said, documenting a sea turtle fluorescing is still pretty freaking cool! Like many scientific discoveries this was totally by happenstance. David was in the Solomon Islands to film biofluorescence in small sharks and coral reefs. And during his observations of sharks and corals glowing Crusher just swims by like, “Dude, I’m all glowing and stuff.”
Checkout the awesome video of it below, and Happy FSF!
Several images circulate on the internet that capture the plight of rapid Arctic climate change, a phenomenon known as Arctic amplification. This image, for me, is the most alarming:
OPAH, OPAH, OPAH!
Recently scientists at NOAA’s South West Fisheries Science Center made a stunning discovery, the worlds first known warm-blooded fish, the moonfish, opah (Lampris guttatus). Until this recent discovery all fish were considered cold-blooded ectotherms – allowing their body temperature to fluctuate with the change in ambient ocean temperature. However, opah’s are different, in that these largely solitary fish regulate their internal body temperature above the ambient temperature of their environment like mammals and birds (other warm-blooded animals).
Raise your hand if you realized there were frogs so translucent you could see their innards? Ok if you actually raised your hand while reading this, kudos, but put it down now. Glass frogs are tiny green organisms whos organs are visible from their underside given the translucent nature of their bellies. There were 148 species of glass frogs, all of which reside in Central and South America. Well make that 149 species of glass frogs now! Recently a new species of glass frog, Hyalinobatrachium dianae, was discovered in in the forested mountains of eastern Costa Rica.
The frog is nocturnal and stands out from other glass frogs because of its long, thin feet and black-and-white eyes. This new species also boasts a distinct call, which frogs produce to attract females. This frogs call is a long tiny whistle similar to the noise produced by insects, which helps explain why this frog went unidentified for so long.

You’ve been there before. You are sitting or standing around and get a mental sensation that you need to “pop your knuckles”. A swift squeeze of your fingers and the tension is relieved. Crisis averted. But why do knuckles make that popping sound when you crack them? If questions like this keep you up at night… maybe you need to reevaluate your priorities. But, if the start of this article has piqued your interest, you will be pleased to know that a a team of researchers, led by the University of Alberta Faculty of Rehabilitation Medicine, have confirmed the reasons for knuckle popping.
