Scientists predict age using only a saliva sample

In a recently patented research, UCLA geneticists have shown and demonstrated how they’ve accurately been able to predict a person’s age just by analyzing a saliva sample. The research could possibly find highly welcomed applications in crime scene investigation, as a forensics tool for pinpointing a suspect’s age. “Our approach supplies one answer to the enduring quest for reliable markers

Introspective individuals spot illusions harder, study says

According to a new study by scientists from University College London, it seems people who find optical illusion solving easier are less inclined to think about the process and understand how they came to that decision. This conclusion came after further analysis of data from a research conducted last year, which showed people with more grey matter in the primary

Amazing 1800s mechanical arm

With today’s technology, prosthetics are not at all uncommon, and what’s even more important, they have become more and more performant, allowing certain actions which would have been impossible a century ago. But even more than a century ago, in the 19th century, people were incredibly creative and resourceful. This prosthetic victorian arm, made out of steel and brass, seems

Brain-like computing is one step closer

The development of a brain-like computer would have numerous and varied benefits, and this achievement is one step closer, according to research published by researchers from the University of Exeter. Unique handling of information The brain is an unique processor from many points of view, displaying many extraordinary abilities, including simultaneous information processing and storage using phase-change material, which is

Remember and forget at the flick of a button

A team of neuro-scientists have managed to restore lost memories to rats by activating a part of their brains through an artificial memory chip – just like a sort of neuro-prosthesis. Further advances backed by this study might lead to the development of important leaps in long-term memory treatment, providing relief for Alzheimer or dementia patients. Researchers from Wake Forest

An Implant for Memory

My Alma mater (USC) is doing some pretty cool things with the human brain. Even when I took a neuroscience class there a couple years ago my professor was working on a prosthetic for the hippocampus, the part of the brain responsible for encoding long term memories.     Well, now researchers have taken another step forward and made an

Giving Primates a Third Arm (and Why it Matters)

When you first hear of the work done by Miguel Nicolelis and his team, though the “cool factor” is high, you might wonder as to the practical application. Miguel has spent the last number of years (and, in fact, most of his career) working to gives our primate cousins a third (robotic) arm. In his new book, Beyond Boundaries, he

Magic Mushrooms can treat depression, anxiety and addiction, study shows

Researchers have found that the mystical experiences obtained by volunteers under the psychoactive substance found in hallucinogenic mushrooms has lead to a substantial improvement of their lives. Although a lot of similar studies have been made showing the beneficial long term effects which come with ingesting psilocybin mushrooms, be it spiritual or physical, this particular research was centered around answering

Study: traumatic brain injuries in Asterix comics

Brain surgeons must have the best sense of humor in the whole scientific community. Seems like a team of German neurosurgeons took the liberty to analyze the hundreds of head injuries roman legionnaires had to suffer at the hands of the ruthless gaul Asterix. They’re results have been remarkable – this my friend is pure gold. From the study abstract:

Scientists create brain with 12 seconds memory

The purple round thing you are looking at is actually a microscopic brain derived from rat neurons, just about 50 of them. Developed by researchers from the University of Pittsburg, it only has a memory of 12 seconds, which is about 11 more than what researchers were hoping for. The brain was created in an attempt to artificially nurture a

Caffeine consumption linked to hallucinations

You can’t believe everything people say, but you sometimes can’t even believe what you hear, especially if you’ve had 3 or more cups of coffee. Australian researchers from La Trobe University have just published a study suggesting that people on a major coffee buzz are prone to hear and seethings that aren’t there. The thins is that this might raise

Study bolsters hope for lung cancer pill

A much anticipated and highly expected drug could come from Pfizer Inc, the biggest drug company in the world; the drug appears to double survival over standard approved drugs, but only against lung tumours with a certain mutation. The drug, called crizotinib, would be the first targeted treatment for the roughly 50,000 people who get this cancer each year worldwide,

Out with the food pyramid, in with the 2.0 food plate

You know the food pyramid, right ? It shows you just approximately how much of each food element you should eat in order to be healthy and make the most out of your life. Well, the Food and Drug Association (FDA) decided that it’s no longer hip enough, and decided to give it a new redesign, with a web 2.0

The colour red increases speed and strength of reactions

What can possibly link together speed, strength, and the colour red ? Nope, it’s not a brand new Ferrari – it’s your muscles ! A new groundbreaking study published in the journal Emotion shows that if you see red, your reactions become faster, more powerful, and you won’t even realize it. Science and sports Of course, due to the crazy

Cigarettes get slapped with bigger and harsher warnings

Remember the days when cigarettes didn’t have to feature labels of all the bad things that can happen if you smoke ? Well, I don’t; but then again, maybe in a few decades people won’t remember the days when cigarettes used to have such ‘light warnings’. Practically, in just a generation or so, things have switched from ‘cigarettes may cause

Woman can literally feel sound after stroke

After she suffered a stroke, a 36-year-old professor started to feel sounds. In the beginning she didn’t know what was happening when a radio announcer’s voice made her tingle, or when during a flight she became physically uncomfortable. Neuroscientist at the City College of New York and the Graduate Center of the City University of New York believe they understand

Team convinces subjects they are Barbie-doll sized

Our perception of size and distances is basically a product of how the brain interprets different visual signals, like for example the size of an object on the retina or its movement across the visual field. Now, if you were shrinking to the size of a doll in your sleep, when you woke up, the world would seem much more

Male+Female bird staggers scientists

Pictured above is a cardinal, and if you don’t see anything special about it yet, you should check out its plumage. Alright, maybe not all of us are ornithologists, so I’ll just set the facts straight. If you look closely, you’ll see that the bird has bright red plumage of a male on its left side and gray, female feathers

Shorties: Adding more calcium to your diet won’t reduce fracture risk

The benefits of calcium in your diet are numerous, but according to a study conducted by University of Sweden researchers. Their study concludes that increasing calcium intake beyond a moderate amount does little to nothing in preventing osteoporosis later in life, or reduce fracture risk. The study, published online Tuesday on the British Medical Journal website, intended to shed some

1 in 5 young adults suffering from high blood pressure in the US

Researchers at the University of North Carolina-Chapel Hill have found that more and more young adults are suffering from a condition that has traditionally been the problem of older adults – high blood pressure. The researchers believe that general problems, such as an unbalanced diet, coffee, and obesity are the main causes for this surge in heart related issues amongst
