New biocompatible, self-healing gel is perfect replacement for cartilages

A team of experts in mechanics, materials, medicine and tissue engineering have managed to create a self replicating gel which can stretch about 21 times its length. The water-based tough gel is also self-healing and biocompatible, which means it could be perfect for people with cartilage injuries. When 1+1 isn’t 2 The new hydrogel (names this way because water is

Loud Music Can Stimulate Your Brain

 Music is LIFE Music makes the world go round, but in recent years youngsters have been warned about listening to too much music at high volumes, advising that it may cause hearing loss in later life. Contrary to this, research in the last few years into the positive reactions of listening to loud music has taken place, and offers an

Pulling all-nighters before tests is counter-productive – does more harm than good

The findings of a new research at UCLA, suggest that cramming all night before a big test, something that we’ve all went through at least once in a point of our lives with personal mixed results, is generally counter-productive as the sleep deprivation acts its toll on cognitive performance. Whether we’re talking about high school or university, especially the latter, we’ve all

Secrets of the ‘Super Agers’: elder people who

Researchers often study and analyze what goes wrong with the brains of people with dementia; but this is not the case here – researchers from Northwestern Medicinecasked themselves exactly the opposite: what happens with the brains of the so-called ‘Super Agers’, elder people who still have terrific memories. Emili Rogalski identified an elite group of people aged over 80, whose

Seizure detector treats epilepsy in rats

Just think about it: a minimally invasive brain stimulator that significantly reduces seizure duration for epilepsy patients. Such a device exists, but sadly, only works in rats so far. The device was tested on nine rats with a ‘petit mal’ form of epilepsy, and it reduced the length of seizures by approximately 60 percent. Most electrical stimulation devices, most notably

Beating cancer by making it forget what it is [TED VIDEO]

Dr. Jay Bradner, a physician and chemical biologist at the Dana-Farber Cancer Institute in Boston, makes beating cancer sound easy – darn easy! Through the wonderful information that epigenetics science has delivered in the past decade, he believes cancer can be defeated simply by re-writing its genetic information such that it forgets that it’s a cancer, and starts behaving like a regular

Malaria genome sequence shows the disease is more challenging, yet offers opportunities

Two recently released studies by teams of international researchers sequenced the genomes of two major strains of the parasitic disease known as malaria. Their findings show that malaria is a lot more resistant than previously thought, but at the same time helps paint a broader picture which will certain aid in developing more effective treatment, which might one day lead

Shorties: Exercise helps ease depression in heart failure patients

Almost half of all patients who suffered some sort of heart failure slip into depression, even though some of them live another few decades after the event. But exercise really is a miracle worker – according to doctors, even in such a delicate case, it can significantly help patients overcome their depression. Researchers randomly assigned more than 2,300 heart failure

Leg ulcer spray accelerates healing

Leg ulcers are nasty problems – and hard ones to get rid of. Now, according to a team of Canadian and American doctors, spraying leg ulcers with a mixture of skin cell mixture may speed up healing, even for nasty cases. Typically, such ulcers develop when high blood pressure in the veins from the legs damages the skin, causing it

Chemical lets blind mice see instantly – no surgery, chips or genetic alteration

Remarkably, researchers University of California, Berkeley  have discovered that a chemical called AAQ can temporarily restore the vision in blind mice. The find might help people suffering from inherited genetic blindness or age-related macular degeneration, and bring back light into their world. The process isn’t quite as easy as applying eye drops, but it’s a whole lot less intrusive than surgery, bio-chips or optogenics,

We make mistakes more often and learn harder when rules change

Someone whose been driving for 20 years, let’s say, in the United States and somehow ends up driving a car in the UK will be in a lot of trouble. Going from right side driving to left side driving, or vice versa, will bewilder just about anyone, and if you’ve gone through such an experience maybe you can relate to

Avian flu jumps from birds to mammals, killing New England baby seals

A novel avian influenza virus has developed the ability to infect aquatic mammals and is responsible for an outbreak of fatal pneumonia that recently struck harbor seals in New England. The announcement was made by researchers from the Center for Infection & Immunity (CII) at Columbia University’s Mailman School of Public Health, the National Oceanic and Atmospheric Association, New England

Smiling facilitates stress recovery

Just grin and bear it – we’ve all heard it at one point or another in our lives, and we’ve probably hated hearing it. But could there be some real scientific fact behind this piece of advice? Can smiling actually help you feel better? Smile psychology In a study forthcoming in Psychological Science, a journal of the Association for Psychological

Fluoride in tap water lowers IQ and hampers child brain development

According to the Fluoride Action Network there are at present 24 independent studies which have a direct link between fluoride contamination from city tap water and reduced IQ, especially in children who are more vulnerable due to developing brains. The most recent one comes from Harvard University, which also came to the same conclusion, namely that of “the possibility of adverse

First ever computer model of a living organism performed

In what can only be described as a milestone in biological and genetic engineering, scientists at Stanford University have, for the first time ever, simulated a complete bacterium. With the organism completely in virtual form, the scientists can perform any kind of modification on its genome and observe extremely quickly what kind of changes would occur in the organism. This

HIV prevention drug approved by the FDA, decision criticized by AIDS support organization

The U.S. Food and Drug Administration recently gave its seal of approval for the introduction of  Truvada on the pharmaceutical market, a drug which allegedly can prevent HIV infection with an effectiveness rate as high as 75 percent when used in combination with safe sex practices. The Aids Healthcare Foundation (AHF), which is largest Aids support organisation in the world, however called the

Earliest modern human genome partially sequenced

Researchers have analyzed the DNA from  7,000-year-old bones of two cavemen unearthed in Spain, and have managed to sequence fragments of their genomes, making them the oldest modern human specimens ever found thus far. Ironically, the researchers found that the cavemen bear little genetic resemblance to people living in the region today, instead sharing ancestry with current populations of northern Europe. The skeletons

Science explains why supermarket tomatoes are less tasty than garden grown

A newly published researchers by scientists at University of California Davis and Cornell University explains why beautiful, perfectly ripped tomatoes, that one can typically pick up from a local supermarket, are ironically less tastier than homegrown tomatoes, which look less appetizing. I had the good fortune of spending most of my early childhood in the countryside, where my grandfolks took

Scientists catalog weird microbes in your body – a few pounds of bacteria is healthy for you

By creating this microbiome catalog, researchers hope to figure out the complex interactions between the countless microbes in our bodies and our immune system. As many already know, germs are not always bad for you – in fact, they are sometimes necessary for a healthy body. But regardless how careless or careful you are with your hygiene, you are carrying

Ecstasy use ‘safe for adults’, B.C. health officials declare

Dr. Perry Kendall, one of B.C.’s leading health officials says taking pure ecstasy, without any other substances, is totally safe for adults – when consumed responsibly. MDMA and street ecstasy MDMA, the pure substance originally synonymous with ecstasy was thought to be responsible for a series of deaths, but according to Dr. Kendall, the life-threatening danger appears only when the
