Sunlight continues to damage skin even after dark
|
view preview
Researchers have discovered that sun exposure gives skin cells a postsunshine hangover that lasts for hours. In fact, UV rays damage skin cells for hours after you've stepped out of the sun - and even if you're in complete darkness!

New ways to stop cancer once it spreads
|
view preview
When a person dies from cancer, the culprit isn't usually the original tumor - it's metastasis, the spread of cancer cells throughout the body. Now, researchers have managed to package a drug in nanoparticles (a microscopic particle with at least one dimension less than 100 nm) so that it can target these cancer cells without, crucially, interfering with normal cells - and report that they've stopped cancer cells from spreading in mice. Nanoparticle research is currently an area of intense scientific research, due to a wide variety of potential applications in biomedical, optical, and electronic fields.

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. ...

Apparently Ibuprofen helps you live longer - not my words
|
view preview
Good news for pain-pill poppers: Ibuprofen (found in Advil) may help you live longer. A new study shows that it increases life span in lab organisms, raising the possibility it does the same thing in people. To put ibuprofen through its paces, biochemist Michael Polymenis of Texas A&M University, College Station, and colleagues gave yeast, nematode worms, and fruit flies doses of the drug that are comparable to what humans would take. The life spans of all three types of organisms increased if they received ibuprofen, the researchers report today in PLOS Genetics. In yeast, for instance, ibuprofen stretched life span by 17%, half of what researchers can produce by cutting the cells’ food supply (another approach to increasing longevity). ...

Band Aid of the Future
|
view preview
Being a person that dislikes the smell or sight of blood, it makes me happy to read that a product that could prevent the leakage of blood has been created. The inventors call it "vetigel", but the "Band Aid of the Future" seems to be a better name. This product is a plant based adhesive that can heal wounds and clot blood within seconds. It has a great potential to revolutionize the Emergency Medicine field. "The gel activates blood’s natural clotting process and is made with biocompatible components that can be absorbed directly into the body. By reassembling onto a wound site, VETIGEL mimics the body’s extracellular matrix and accelerates the production of fibrin, which enables the body to clot rapidly." Make sure to watch these videos to ...

Finally, we are going back to the moon!
|
view preview
For all those doubters out there, this one is for you. Lunar Mission One, which was announced today at the Royal Society in London, will be the UK’s first trip to the moon. It’s an exploratory robotic mission that hopes to see a probe land on the moon’s South Pole within the next ten years, should funding allow. The aim of the venture is to drill through the surface, reaching a depth of at least 20 meters, but perhaps as deep as 100 meters. By analyzing this 4.5 billion year old rock that has been shielded from cosmic radiation and meteor bombardment, scientists hope to increase our understanding of the origins and evolution of the moon, solar system and even our planet. Furthermore, it should also inform us of the practicality of a permanent ...

Good bacteria helps to defend your brain
|
view preview
The microbes that live in your body outnumber your cells 10 to one. Recent studies suggest these tiny organisms help us digest food and maintain our immune system. Now, researchers have discovered yet another way microbes keep us healthy: They are needed for closing the blood-brain barrier, a molecular fence that shuts out pathogens and molecules that could harm the brain.

Why do we listen to sad music?
|
view preview
No one wants to be sad. So why do we love listening to sad songs so much? New research suggests that we're drawn to sad songs because they evoke mostly positive emotions, which is great for our mental health. According to the study published by the journal PLOS One, researchers found that "a wide range of complex and partially positive emotions, such as nostalgia, peacefulness, tenderness, transcendence, and wonder," were brought out in the participants that took part in the study by sad music. These are emotions are all healthy, feel-good emotions. The researchers concluded that "Music-evoked sadness plays a role in well-being, by providing consolation as well as regulating negative moods and emotions."

When's the best time to make a decision?
|
view preview
You might think that it's better to be well-fed rather than starving when you're trying to make a big, life-changing decision, but new research suggests quite the opposite. According to a research study conducted by Utrecht University in the Netherlands, people who were hungry because of having fasted overnight perform better on a complex decision task than sated people. ( Click here to read the research). This provides a first piece of evidence that the hot state of hunger improves, rather than compromises, advantageous decision making. Their experimental evidence suggests that the "hot state of hunger promoted rather than compromised complex decisions with uncertain outcomes that are advantageous in the long run as hungry participants were ...

Trippy mushrooms

view preview
Users of magic mushrooms often report altered states of consciousness and a synesthesia-like melding of the senses. Now, scientists may have figured out why: Psilocybin changes the brain’s wiring, creating a hyperconnected brain that contains links between regions that don’t normally communicate with each other. Communication between brain networks in people given psilocybin (right) or a non-psychedelic compound (left). ...
