From performing surgery and flying planes to babysitting kids and driving cars, today’s robots can do it all. With chatbots such as Eugene Goostman recently being hailed as “passing” the Turing test, it appears robots are becoming increasingly adept at posing as humans. While machines are becoming ever more integrated into human lives, the need to imbue them with a sense of morality becomes increasingly urgent. But can we really teach robots how to be good?
New research suggests the better a parent understands the daily experiences of their teen, the better the mental health of the teen.
Moreover, having a parent who “gets” a teen’s daily life may influence the way a teen’s body responds to stress on a cellular level, improving physical health.

This is what it looks like when a public health agency does a mic drop.
On Monday, Vox unearthed some charts that the Centers for Disease Control and Prevention put together back in 2011 to illustrate the efficacy of vaccines. As they say, the numbers speak for themselves.
The more curious we are about a topic, the easier it is to learn information about that topic. New research publishing online October 2 in the Cell Press journal Neuron provides insights into what happens in our brains when curiosity is piqued. The findings could help scientists find ways to enhance overall learning and memory in both healthy individuals and those with neurological conditions.
"Our findings potentially have far-reaching implications for the public because they reveal insights into how a form of intrinsic motivation — curiosity — affects memory. These findings suggest ways to enhance learning in the classroom and other settings," says lead author Dr. Matthias Gruber, of University of California at Davis.

Many of the choices we make are informed by experiences we’ve had in the past. But occasionally we’re better off abandoning those lessons and exploring a new situation unfettered by past experiences. Scientists at the Howard Hughes Medical Institute's Janelia Research Campus have shown that the brain can temporarily disconnect information about past experience from decision-making circuits, thereby triggering random behavior.
In a big step for securing critical information systems, such as medical records in clinical settings, researchers have created a new approach to computer security that authenticates users continuously while they are using a terminal and automatically logs them out when they leave or when someone else steps in to use their terminal.
With almost all of the U.S. population armed with cellphones — and close to 80 percent carrying a smartphone — mobile phones have become second-nature for most people.
What’s coming next, say University of Washington researchers, is the ability to interact with our devices not just with touchscreens, but through gestures in the space around the phone. Some smartphones are starting to incorporate 3-D gesture sensing based on cameras, for example, but cameras consume significant battery power and require a clear view of the user’s hands.
UW engineers have developed a new form of low-power wireless sensing technology that could soon contribute to this growing field by letting users “train” their smartphones to recognize and respond to specific hand gestures near the phone.
Web-based training targeted at college-aged men is an effective tool for reducing the number of sexual assaults on U.S. campuses, according to a researcher. The RealConsent program reduced sexually violent behavior and increased the likelihood a male student would intervene to prevent a sexual assault, said one author.
More than 700 male undergraduate students at a large university were recruited to take part in the study, which surveyed them before the start of the training modules, after the training and six months later. The six-month follow-up found RealConsent participants were more likely to intervene to prevent sexual assault and less likely to perpetrate sexual violence than a control group.
The study from researchers at the University of Oxford in the United Kingdom included 147 adults between the ages of 20 and 84. Researchers examined the link between sleep difficulties, such as having trouble falling asleep or staying asleep at night, and brain volume.
Can a stack of computer servers survive an earthquake?
In high-seismic regions, new facilities often are engineered with passive protective systems that provide overall seismic protection. But often, existing facilities are conventional fixed-base buildings in which seismic demands on sensitive equipment located within are significantly amplified. In such buildings, sensitive equipment needs to be secured from these damaging earthquake effects.
Ah, the internet. It lets us do so many things: from ordering pizza to browsing endless cat pictures and now… telepathy?
A study by a group of international scientists published in PLOS One found a brain could transmit a message to another brain through internet channels, and as if that weren’t enough — they did it across continents.
I put this on my chalkboard. :)
