Beyerstein, Ph.D. To the casual observer, handwriting analysis enjoys greater plausibility than other occult or pseudoscientific ways of reading personality. Take astrology or palmistry, for instance. It is hard for a thinking person today to imagine how the stars or creases on the palm could affect human behavior. But it seems at least possible that, inasmuch as writing is a form of expressive behavior, it might reveal something about ourselves.

Thin Film Interference - The Art of Physics (with POV Ray) Is there something genetically or physiologically that makes someone a "morning person" vs not? : askscience. Beaming into the Rat World: Enabling Real-Time Interaction between Rat and Human Each at Their Own Scale. Immersive virtual reality (IVR) typically generates the illusion in participants that they are in the displayed virtual scene where they can experience and interact in events as if they were really happening.
Teleoperator (TO) systems place people at a remote physical destination embodied as a robotic device, and where typically participants have the sensation of being at the destination, with the ability to interact with entities there. In this paper, we show how to combine IVR and TO to allow a new class of application. What causes the bend in a banana? Why don't they grow straight? : askscience.

Antioxidants: Beyond the Hype - What Should I Eat? Table of Contents Introduction The body’s trillion or so cells face formidable threats, from lack of food to infection with a virus.

Background and Aims Questions over the clinical significance of cannabis withdrawal have hindered its inclusion as a discrete cannabis induced psychiatric condition in the Diagnostic and Statistical Manual of Mental Disorders (DSM IV).
This study aims to quantify functional impairment to normal daily activities from cannabis withdrawal, and looks at the factors predicting functional impairment. In addition the study tests the influence of functional impairment from cannabis withdrawal on cannabis use during and after an abstinence attempt. Methods and Results A volunteer sample of 49 non-treatment seeking cannabis users who met DSM-IV criteria for dependence provided daily withdrawal-related functional impairment scores during a one-week baseline phase and two weeks of monitored abstinence from cannabis with a one month follow up. Parental divorce linked to stroke in males. Men with divorced parents are significantly more likely to suffer a stroke than men from intact families, shows a new study from the University of Toronto.
The study, to be published this month in the International Journal of Stroke, shows that adult men who had experienced parental divorce before they turned 18 are three times more likely to suffer a stroke than men whose parents did not divorce. Women from divorced families did not have a higher risk of stroke than women from intact families.
"The strong association we found for males between parental divorce and stroke is extremely concerning," says lead author Esme Fuller-Thomson, Sandra Rotman Chair at University of Toronto's Factor-Inwentash Faculty of Social Work and Department of Family and Community Medicine. Pressure in Mount Fuji is now higher than last eruption, warn experts. The pressure in Mount Fuji's magma chamber is now higher than it was in 1707, the last time the nearly 4,000-metre-high Japanese volcano erupted, causing volcanologists to speculate that a disaster is imminent.
The new readings, taken by the National Research Institute for Earth Science and Disaster Prevention, reveal that the pressure is at 1.6 megapascals, nearly 16 times the 0.1 megapascals it takes to trigger an eruption. This, lead volcanologist on the case Eisuke Fujita told Kyodo News, is "not a small figure". If energy can't be created or destroyed how much energy is there in the universe? : askscience. LG produces the first flexible cable-type lithium-ion battery. LG Chem, a member of the LG conglomerate/chaebol and one of the largest chemical companies in the world, has devised a cable-type lithium-ion battery that’s just a few millimeters in diameter, and is flexible enough to be tied in knots, worn as a bracelet, or woven into textiles.
The underlying chemistry of the cable-type battery is the same as the lithium-ion battery in your smartphone or laptop — there’s an anode, a lithium cobalt oxide (LCO) cathode, an electrolyte — but instead of being laminated together in layers, they’re twisted into a hollow, flexible, spring-like helix. LG Chem’s battery starts with thin strands of copper wire, which are coated with a nickel-tin (Ni-Sn) alloy to create the anode.
These strands are twisted into a yarn, and then wrapped tightly around a 1.5mm-diameter rod. The rod is removed, leaving a strong spring. Baldness cure could be on shelves in two years. Sacrificing sleep to study can lead to academic problems. Regardless of how much a high school student generally studies each day, if that student sacrifices sleep in order to study more than usual, he or she is more likely to have academic problems the following day. Because students tend to increasingly sacrifice sleep time for studying in the latter years of high school, this negative dynamic becomes more and more prevalent over time. Those are the findings of a new longitudinal study that focused on daily and yearly variations of students who sacrifice sleep to study.
The research was conducted at the University of California, Los Angeles (UCLA) and appears in the journal Child Development. "Sacrificing sleep for extra study time is counterproductive," says Andrew J. Fuligni, professor of psychiatry and biobehavioral sciences and a senior scientist at the Jane and Terry Semel Institute of Neuroscience and Human Behavior at UCLA, who worked on the study. Bonobo genius makes stone tools like early humans did - life - 21 August 2012. Video: Watch this bonobo go to all ends to get food Kanzi the bonobo continues to impress.
Not content with learning sign language or making up "words" for things like banana or juice, he now seems capable of making stone tools on a par with the efforts of early humans. Eviatar Nevo of the University of Haifa in Israel and his colleagues sealed food inside a log to mimic marrow locked inside long bones, and watched Kanzi, a 30-year-old male bonobo chimp, try to extract it.
While a companion bonobo attempted the problem a handful of times, and succeeded only by smashing the log on the ground, Kanzi took a longer and arguably more sophisticated approach. Black belts' white matter shows how a powerful punch comes from the brain. Brain scans have revealed distinctive features in the brain structure of karate experts, which could be linked to their ability to punch powerfully from close range.
Researchers from Imperial College London and UCL (University College London) found that differences in the structure of white matter – the connections between brain regions – were correlated with how black belts and novices performed in a test of punching ability. Karate experts are able to generate extremely powerful forces with their punches, but how they do this is not fully understood. Previous studies have found that the force generated in a karate punch is not determined by muscular strength, suggesting that factors related to the control of muscle movement by the brain might be important. Harvard cracks DNA storage, crams 700 terabytes of data into a single gram.
A bioengineer and geneticist at Harvard’s Wyss Institute have successfully stored 5.5 petabits of data — around 700 terabytes — in a single gram of DNA, smashing the previous DNA data density record by a thousand times. The work, carried out by George Church and Sri Kosuri, basically treats DNA as just another digital storage device. Instead of binary data being encoded as magnetic regions on a hard drive platter, strands of DNA that store 96 bits are synthesized, with each of the bases (TGAC) representing a binary value (T and G = 1, A and C = 0).
To read the data stored in DNA, you simply sequence it — just as if you were sequencing the human genome — and convert each of the TGAC bases back into binary. To aid with sequencing, each strand of DNA has a 19-bit address block at the start (the red bits in the image below) — so a whole vat of DNA can be sequenced out of order, and then sorted into usable data using the addresses.
