Want to get rid of your double chin, now you can without surgery
|
view preview
An injectable drug, called ATX-101, currently being tested melts away "submental fat", better known as the double chin. According to its makers, ATX-101 can be injected in a clinic and takes just five minutes. It consists of deoxycholic acid, a naturally-occurring molecule that helps us break down fat, which effectively destroys the membranes of fat cells, causing them to burst and then be metabolised by the body. ...

Developing immunity to the common cold
|
view preview
Summer is officially over, and fall has arrived. With this season comes runny noses and doctor visits. Save yourself the time and money, because it's either the common cold or the flu, both of which have no cure other than to rest and endure the discomfort. Luckily, you can be immunized for the flu, but not the cold. In fact, many people battle the cold several times a year, rather than developing a natural immunity towards it, why is that? The primary reason that immunity generally does not develop against the common cold is that there is not a single cause of the disease. Over 200 serotypes of viruses, including enteroviruses (previously called rhinoviruses), coronaviruses, and adenoviruses, can cause the symptoms of the common cold. Ther ...

A scam-artist or a medical doctor?
|
view preview
I've been advocating this for years. Just because you're a doctor and you're on TV, doesn't make you a know-it-all. Researchers from the University of Alberta have found that half the advice on Dr. Oz is wrong or has no evidence to back it up. In fact, on average, the shows give their viewers around 12 different recommendations per episode. But only half of them are supported by research. Just comes to show that people will believe anything they see on TV. When there is money to be made and an agenda to be pushed, lies will follow. ...

Brain just can't catch a break

view preview
The importance of adequate, non-distracted, deep sleep could not be emphasized enough. Recent research has put the brain yet again under the spotlight, this time only to shed some light on one more reason we should be getting our sleep and why. Make sure to watch the video above. It is hands down, one of the best TED talks I have listened to. As for now, I'mma go make my CSF flush my amyloid betas Nighty, night!

Insights into the Hippocampus
|
view preview
When Henry Molaison (now widely known as H.M.) cracked his skull in an accident, he began blacking out and having seizures. In an attempt to cure him, daredevil surgeon, Dr. William Skoville, removed H.M.'s hippocampus. Luckily, the seizures did go away — but so did his long-term memory! Sam Kean walks us through this astonishing medical case, detailing everything H.M. taught us about the brain and memory.

Cancer, could it be just bad luck?
|
view preview
In a paper this week in Science, two scientists at John Hopkins have united biology and mathematics to propose a mathematical formula to explain the genesis of cancer. Take the number of cells in an organ, identify what percentage of them are long-lived stem cells, and determine how many times the stem cells divide. With every division, there’s a risk of a cancer-causing mutation in a daughter cell. Thus, Tomasetti and Vogelstein reasoned, the tissues that host the greatest number of stem cell divisions are those most vulnerable to cancer. When Tomasetti crunched the numbers and compared them with actual cancer statistics, he concluded that this theory explained two-thirds of all cancers. “Using the mathematics of evolution, you can really ...

Pre-crastination
|
view preview
Some of us may be guilty of procrastination, but we all are pre-crastinators at some level. Procrastination is a serious problem to many of us that like to put off work and cram the night before. Not only is procrastination a behavioral problem, but also one with a psychological implication. Procrastination is the "thief of time". On the other hand, precrastination, discovered to be the complete opposite, is the tendency to do things ahead of time - and really ahead of time- just for the sake of completion. Precrastination was found to be exhibited in pigeons as well. And the fact that we and pigeons have separated in phylogeny 300 million years ago suggests that precrastination is a behavior also found earlier in phylogeny. How has this be ...

This strange disease turns one's skin into bone
|
view preview
Known an fibrodysplasia ossificans progressive, or FOB for short, this disease can suddenly turn a person’s tissues and muscles into bone, thereby permanently immobilizing parts of the bodies. Joints such as elbows or ankles may become frozen in place; jaw motion can be impeded and the rib cage fixed, making eating or even breathing difficult. Currently, no cure exists to combat this rare condition.

Who knew chili peppers were good for you

Exposure to cold and eating chili peppers both appear to increase the activity of brown fat cells, which burn energy, rather than store it as typical "white" fat cells do, a study has found.

Here's what happens when you do get stitches: Here's what happens without stitches: And finally, this scenario often leads to contamination. In this case, you'd get this: ...
