The Tech Elite are Moving Left this Election Cycle (May 5, 2016)
This election cycle, the tech elite are almost exclusively backing liberals: Tesla’s Elon Musk donated to Hillary Clinton, Facebook’s Mark Zuckerberg gave handsomely to the San Francisco Democratic Party organization, and Microsoft’s Bill Gates gave to three Democratic congressmen. Though often seen as a libertarian stronghold, no household Silicon Valley names publicly donated to the small government torchbearers, Rand Paul or Ted Cruz. Far from being the exception, recent data shows that...Read More
Researchers Explain How Stereotypes Keep Girls Out of Computer Science Classes (May 4, 2016)
Despite valiant efforts to recruit more women, the gender gap in the fields collectively known as STEM — science, technology, engineering, and math — is not getting any better. The gaps in computer science and engineering are the largest of any major STEM discipline. Nationally, less than 20% of bachelor’s degrees in these fields go to women. Women are missing out on great jobs, and society is missing out on the innovations women could be making in new technology. Good work is being done t...Read More
Now Computers Can Tell When You're Bored (May 4, 2016)
Boredom manifests itself in more than yawns and glazed eyes. Subtle body cues called noninstrumental movements—squirming, scratching, shifting—also give away a person's mental state. Like teachers and other public speakers, machines can now also pick up on these telltale signs of restlessness. A new study reveals that when computer users tune in to on-screen material, their fidgeting lessens—and algorithms can use that information to discern attentiveness in real time.
The Benefits of Being a ‘Dumb’ Girl in Computer Science (May 3, 2016)
Prior to changing my major to computer science, I was studying molecular biology and I hated it. I was studying it for all the wrong reasons and the more I kept trying at it the more both it and I fell apart. I was seriously considering dropping out of college all together until one day during one of my labs my partner said something to me that I will never forget and it started a chain reaction of events that led me directly to computer science.
Computers Play a Crucial Role in Preserving the Earth (May 3, 2016)
Computers have helped revolutionize the commercial world and transformed the lives of the general public through the development of the Internet and mobile technologies like the iPhone. But, practically speaking, they have done little for the good of our planet. This troubled Carla Gomes, a computer science professor at Cornell University, and led her to embark on an effort to develop computational methods that can help cultivate a more sustainable world.
Strengthening Authentication Through Big Data (May 2, 2016)
The fact that plain passwords are no longer safe to protect our digital identities is no secret. For years, the use of two-factor authentication (2FA) and multi-factor authentication (MFA) as a means to ensure online account security and prevent fraud has been a hot topic of discussion. Technological advances, especially in the mobile industry, have created new possibilities, and manufacturers and vendors are offering various multi-factor solutions in the domain of biometrics, physical tokens, s...Read More
The Frustrated Science Student Behind Sci-Hub (May 2, 2016)
Beyond being the founder of Sci-Hub, the world’s largest pirate site for academic papers, and risking arrest as a result, Alexandra Elbakyan is a typical science graduate student: idealistic, hard-working, and relatively poor. In 1988, when Elbakyan was born in Kazakhstan, the Soviet Union was just beginning to crumble. Books about dinosaurs and evolution fascinated her early on. “I also remember reading Soviet science books that provided scientific explanations for miraculous events thought...Read More
Are We Living in a Computer Simulation? (May 1, 2016)
If you, me and every person and thing in the cosmos were actually characters in some giant computer game, we would not necessarily know it. The idea that the universe is a simulation sounds more like the plot of “The Matrix,” but it is also a legitimate scientific hypothesis. Researchers pondered the controversial notion at the annual Isaac Asimov Memorial Debate at the American Museum of Natural History.
The Light Stuff: A Brand-New Way to Produce Electron Spin Currents (May 1, 2016)
With apologies to Isaac Asimov, the most exciting phase to hear in science isn't "Eureka," but "That's funny..." A "that's funny" moment in a Colorado State University physics lab has led to a fundamental discovery that could play a key role in next-generation microelectronics. Publishing in Nature Physics, the scientists, led by Professor of Physics Mingzhong Wu in CSU's College of Natural Sciences, are the first to demonstrate using non-polarized light to produce in a metal what's called a spi...Read More
Google is Funding Screenplays that Change the Image of Computer Science (Apr 30, 2016)
Google wants to help change the way computer science is depicted in the media, so the company is funding a new grant for screenwriters. The company has teamed up with The Black List, a site that lets filmmakers share their scripts online, to look for three writers to create screenplays or teleplays that "changes the image of computer science or computer scientists, [particularly] as it applies to women and minorities." Each will be awarded up to $15,000 and have six months to work on their proje...Read More
Robotic Consensus (Apr 30, 2016)
Planning algorithms for teams of robots fall into two categories: centralized algorithms, in which a single computer makes decisions for the whole team, and decentralized algorithms, in which each robot makes its own decisions based on local observations. With centralized algorithms, if the central computer goes offline, the whole system falls apart. Decentralized algorithms handle erratic communication better, but they’re harder to design, because each robot is essentially guessing what the o...Read More
Bullied Parrot Finds New Confidence with 3D-Printed Beak (Apr 29, 2016)
A palm cockatoo named Huizai — Chinese for Grey Boy — has gotten a new lease on life, thanks to the wonders of technology. The parrot who lives in a Nanjing zoo in Jiangsu, China, was on the verge of losing its beak (and respect from its peers) until he was fitted with a new beak. According to one of his keepers, Chen Wei, Huizai's beak started showing cracks after a fight with another parrot, but those cracks got worse and most of it started to fall off. Both Huizai's confidence and appetit...Read More

How Social Entrepreneurship is Making a Difference in the World (Apr 28, 2016)
We have grown accustomed to the Silicon Valley zeal driving startups to develop new technologies that will disrupt the market in yet another way. On-demand apps like Uber are aimed at making our lives easier by saving us time and money. In other parts of the world, people are faced with different kinds of “problems.” They aren’t so much worried about finding an app that will water their plants — their actual concern is finding water. An example, among many others, is India.
To Make Computers Better, Let Them Get Sloppy (Apr 27, 2016)
Krishna Palem's computers won’t win any awards for accuracy. Most of the time they can’t even add up correctly. For them, 2 + 2 might as well be 5. But don’t be fooled by the wobbly arithmetic. Palem is making machines that could represent a new dawn for computing. Inaccuracy is not something we typically associate with computers. Since Alan Turing laid down their ground rules in the 1930s, computers have been sticklers for precision, built on the principle of following step-by-step instru...Read More

Violent Video Games Eventually Lose Their Ability to Produce Guilt in Gamers (Apr 25, 2016)
Rapidly advancing technology has created ever more realistic video games. Images are sharp, settings have depth and detail, and the audio is crisp and authentic. At a glance, it appears real. So real, that research has consistently found that gamers feel guilty committing unjustified acts of violence within the game. Now, a new University at Buffalo-led study suggests that the moral response produced by the initial exposure to a video game decreases as experience with the game develops. The find...Read More
'Brain-Inspired' Supercomputer Explores Deep Learning for U.S. Nuclear Program (Apr 25, 2016)
A new low-power, "brain-inspired" supercomputing platform based on IBM chip technology will soon start exploring deep learning for the U.S. nuclear program. Based on IBM’s TrueNorth chip, it will have the equivalent of 16 million neurons and 4 billion synapses but consume energy like a tablet PC. IBM says it wants to make intelligent computers that can make decisions like humans, and this new technology is an enormous step in that direction.
System Predicts 85 Percent of Cyber-Attacks Using Input From Human Experts (Apr 19, 2016)
Today's security systems usually fall into one of two categories: human or machine. So-called "analyst-driven solutions" rely on rules created by living experts and therefore miss any attacks that don't match the rules. Meanwhile, today's machine-learning approaches rely on "anomaly detection," which tends to trigger false positives that both create distrust of the system and end up having to be investigated by humans, anyway. But what if there were a solution that could merge those two worlds? ...Read More
Robots Could Get 'Touchy' with Self-Powered Smart Skin (Apr 19, 2016)
Smart synthetic skins have the potential to allow robots to touch and sense what's around them, but keeping them powered up and highly sensitive at low cost has been a challenge. Now scientists report in the journal ACS Nano a self-powered, transparent smart skin that is simpler and less costly than many other versions that have been developed. Endowing robots and prosthetics with a human-like sense of touch could dramatically advance these technologies. Toward this goal, scientists have come up...Read More
