A cheap antibiotic normally prescribed to teenagers for acne is to be tested as a treatment to alleviate the symptoms of psychosis in patients with schizophrenia, in a trial that could advance scientific understanding of the causes of mental illness.
men are more attracted to women wearing red compared to other colours because they believe they are less likely to be rejected.Psychologists behind the research claim the colour red carries subtle but powerful messages about how receptive a woman might be to romantic advances and so men find it more alluring.
Time and space are the two fundamental dimensions of our lives. All forms of human behavior require us to process and understand information we receive from our environment in either spatial or temporal patterns. Even though mental timing (temporal processing) research is in a stage of infancy (when compared to spatial processing) important insights regarding the human brain clock have emerged.
We often worry about lying awake in the middle of the night – but it could be good for you. A growing body of evidence from both science and history suggests that the eight-hour sleep may be unnatural.In the early 1990s, psychiatrist Thomas Wehr conducted an experiment in which a group of people were plunged into darkness for 14 hours every day for a month.It took some time for their sleep to regulate but by the fourth week the subjects had settled into a very distinct sleeping pattern. They slept first for four hours, then woke for one or two hours before falling into a second four-hour sleep.
Learning mindfulness and meditation techniques can help us minimize stressful mind-wandering and cultivate emotional wellness and happiness. In the coming years further studies of how adult brains are able to change will help us better understand whats involved in emotional well being and promote better mental health for everyone.
It finally happened. Neuroscience technology can now reliably read our minds. Its an accepted fact that is no longer in dispute. Scientists working at the University of California, Berkeley, have successfully decoded brain activities into audible sounds. In other words, our inner thoughts can be translated into sounds clearly articulated by a computer. Needless to say, there are a whole lot of caveats attached to this claim. For a start, in order to make this kind of reading possible, it requires some 256 electrodes be surgically attached to the scalps of at least 15 volunteers. Furthermore, theres a minefield of ethical issues attached to this endeavor that needs to be sorted out.
Michael Gazzaniga, one of the world’s leading researchers in cognitive neuroscience, describes the mystery of free will:If you think about it this way, if you are a Martian coming by earth and looking at all these humans and then looking at how they work you wouldntit would never dawn on you to say, Well, now, this thing needs free will! What are you talking about?Whether you are a parent, a philosopher, or the CEO of Facebook, it’s a concept that youll inevitably have to bang your head against — the individual right to choose what one does, what one doesn’t do, what one is exposed to. Most of us are certain that we have free will, though what exactly this amounts to is much less certain, says theencyclopedia of philosophy.
If the man in your life is suddenly on his best behaviour, have a look around.Men apparently become nicer, kinder and more caring when there is a beautiful woman nearby.Women, however, feel less of a need to impress and remain true to themselves, even when there is a handsome chap hovering in the wings.
A new range of artificial, electrically-powered organs are now under development, including hearts, kidneys, and bladder sphincter, and work has begun on fully-functioning artificial limbs such as hands, fingers, and even eyes. But they all have one Achilles heel: they need electricity to run. The fuel cells are made from a compressed push of enzymes and carbon nanotubes.
At heart, biofuel cells are incredibly simple. They are made of two special electrodes – one is endowed with the ability to remove electrons from glucose, the other with the ability to donate electrons to molecules of oxygen and hydrogen, producing water.
Pop these electrodes into a solution containing glucose and oxygen, and one will start to rip electrons off the glucose and the other will start dumping electrons onto oxygen. Connect the electrodes to a circuit and they produce a net flow of electrons from one electrode to the other via the circuit – resulting in an electrical current.Glucose and oxygen are both freely available in the human body, so hypothetically, a biofuel cell could keep working indefinitely. “A battery consumes the energy stored in it, and when it’s finished, it’s finished. A biofuel cell in theory can work without limits because it consumes substances that come from physiological fluids, and are constantly being replenished,” said Dr Cosnier.
Myth 2: Your Memory Is An Exact Account of What You See and Experience
Some of us have better memories than others, but no memory is perfect. If you need proof, close your eyes and try to imagine the face of someone you know. In fact, try to imagine your own face. While you’ll be able to conjure up a decent idea of the way you or anyone else looks, you won’t be able to envision every last detail. This is because our memories don’t recall anything we see, hear, sell, taste, or touch with much detail at all. Instead, as psychologist Dan Gilbert points out in his book Stumbling On Happiness, our brains record the seemingly necessary details and fill in the rest when it’s time to remember:[T]he elaborate tapestry of our experience is not stored in memory-at least not in its entirety. Rather, it is compressed for storage by ﬁrst being reduced to a few critical threads, such as a summary phrase (“Dinner was disappointing”) or a small set of key features (tough steak, corked wine, snotty waiter). Later, when we want to remember our experience, our brains quickly reweave the tapestry by fabricating-not by actually retrieving-the bulk of the information that we experience as a memory. This fabrication happens so quickly and effortlessly that we have the illusion (as a good magician’s audience always does) that the entire thing was in our heads the entire time.Gilbert’s conclusions come from memory researcher Daniel Schacter, who believes the construction of memory is very similar to the way we imagine the future:We have argued in recently that memory plays a critical role in allowing individuals to imagine or simulate events that might occur in their personal futures. We have further suggested that understanding memory’s role in future event simulation may be important for understanding the constructive nature of memory, because the former requires a system that allows flexible recombination of elements of past experience, which may also contribute to memory errors.While a little common sense and life experience can demonstrate the imperfections in your (and everyone else’s) memory, Schacter’s research points to two important things: we’re no good at recalling past events or imagining the future because our process for doing either is essentially the sameat least as far as our brain functionality is concerned. While this points to much more of a problem than a solution, it certainly helps to remember that no memory is perfect and we’re all designed to recall with error. Next time someone gets something wrong, it’s at least worth remembering that.
