History will probably show that humans are the likely cause for the mass disappearance and death of honey bees around the world.
So, while ecologists try to understand why and how to reverse bee death and colony collapse, engineers are busy building alternatives to our once nectar-loving friends. Meet RoboBee, also known as the Micro Air Vehicles Project.
From Scientific American:
We take for granted the effortless flight of insects, thinking nothing of swatting a pesky fly and crushing its wings. But this insect is a model of complexity. After 12 years of work, researchers at the Harvard School of Engineering and Applied Sciences have succeeded in creating a fly-like robot. And in early May, they announced that their tiny RoboBee (yes, it’s called a RoboBee even though it’s based on the mechanics of a fly) took flight. In the future, that could mean big things for everything from disaster relief to colony collapse disorder.
The RoboBee isn’t the only miniature flying robot in existence, but the 80-milligram, quarter-sized robot is certainly one of the smallest. “The motivations are really thinking about this as a platform to drive a host of really challenging open questions and drive new technology and engineering,” says Harvard professor Robert Wood, the engineering team lead for the project.
When Wood and his colleagues first set out to create a robotic fly, there were no off the shelf parts for them to use. “There were no motors small enough, no sensors that could fit on board. The microcontrollers, the microprocessors–everything had to be developed fresh,” says Wood. As a result, the RoboBee project has led to numerous innovations, including vision sensors for the bot, high power density piezoelectric actuators (ceramic strips that expand and contract when exposed to an electrical field), and a new kind of rapid manufacturing that involves layering laser-cut materials that fold like a pop-up book. The actuators assist with the bot’s wing-flapping, while the vision sensors monitor the world in relation to the RoboBee.
“Manufacturing took us quite awhile. Then it was control, how do you design the thing so we can fly it around, and the next one is going to be power, how we develop and integrate power sources,” says Wood. In a paper recently published by Science, the researchers describe the RoboBee’s power quandary: it can fly for just 20 seconds–and that’s while it’s tethered to a power source. “Batteries don’t exist at the size that we would want,” explains Wood. The researchers explain further in the report: ” If we implement on-board power with current technologies, we estimate no more than a few minutes of untethered, powered flight. Long duration power autonomy awaits advances in small, high-energy-density power sources.”
The RoboBees don’t last a particularly long time–Wood says the flight time is “on the order of tens of minutes”–but they can keep flapping their wings long enough for the Harvard researchers to learn everything they need to know from each successive generation of bots. For commercial applications, however, the RoboBees would need to be more durable.

Artist Ai Weiwei has suffered at the hands of the Chinese authorities much more so than Andy Warhol’s brushes with surveillance from the FBI. Yet the two are remarkably similar: brash and polarizing views, distinctive art and creative processes, masterful self-promotion, savvy media manipulation and global ubiquity. This is all the more astounding given Ai Weiwei’s arrest, detentions and prohibition on travel outside of Beijing. He’s even made it to the Venice Biennale this year — only his art of course.

For centuries biologists, zoologists and ecologists have been mapping the wildlife that surrounds us in the great outdoors. Now a group led by microbiologist Noah Fierer at the University of Colorado Boulder is pursuing flora and fauna in one of the last unexplored eco-systems — the home. (Not for the faint of heart).
“… But You Can Never Leave”. So goes one of the most memorable of lyrical phrases from The Eagles (Hotel California).


In 1960 radio astronomer Frank Drake began the first systematic search for intelligent signals emanating from space. He was not successful, but his pioneering efforts paved the way for numerous other programs, including SETI (Search for Extra-Terrestrial Intelligence). The Drake Equation is named for him, and put simply, gives an estimate of the number of active, extraterrestrial civilizations with methods of communication in our own galaxy. Drake postulated the equation as a way to get the scientific community engaged in the search for life beyond our home planet.
If you are an English speaker and are over the age of 39 you may be pondering the fate of the English language. As the younger generations fill cyberspace with terabytes of misspelled texts and tweets do you not wonder if gorgeous grammatical language will survive? Are the technophobes and anti-Twitterites doomed to a future world of #hashtag-driven conversation and ADHD-like literature? Those of us who care are reminded of George Orwell’s 1946 essay “Politics and the English Language”, in which he decried the swelling ugliness of the language at the time.

Good customer service once meant that a store or service employee would know you by name. This person would know your previous purchasing habits and your preferences; this person would know the names of your kids and your dog. Great customer service once meant that an employee could use this knowledge to anticipate your needs or personalize a specific deal. Well, this type of service still exists — in some places — but many businesses have outsourced it to offshore call center personnel or to machines, or both. Service may seem personal, but it’s not — service is customized to suit your profile, but it’s not personal in the same sense that once held true.
Ubiquitous connectivity for, and between, individuals and businesses is widely held to be beneficial for all concerned. We can connect rapidly and reliably with family, friends and colleagues from almost anywhere to anywhere via a wide array of internet enabled devices. Yet, as these devices become more powerful and interconnected, and enabled with location-based awareness, such as GPS (Global Positioning System) services, we are likely to face an increasing acute dilemma — connectedness or privacy?
Researchers are continuing to make great progress in unraveling the complexities of aging. While some fingers point to the shortening of telomeres — end caps — in our chromosomal DNA as a contributing factor, other research points to the hypothalamus. This small sub-region of the brain has been found to play a major role in aging and death (though, at the moment only in mice).
Stephen Wolfram, physicist, mathematician and complexity theorist, has taken big data ideas to an entirely new level — he’s quantifying himself and his relationships. He calls this discipline personal analytics.
Yesterday, May 10, 2013, scientists published new measures of atmospheric carbon dioxide (CO2). For the first time in human history CO2 levels reached an average of 400 parts per million (ppm). This is particularly troubling since CO2 has long been known as the most potent heat trapping component of the atmosphere. The sobering milestone was recorded from the Mauna Loa Observatory in Hawaii — monitoring has been underway at the site since the mid-1950s.
We live in a world of brands, pitches, advertising, promotions, PR, consumer research, product placement, focus groups, and 24/7 spin. So, it should come as no surprise that even that ubiquitous and utilitarian listing of food and drink items from your local restaurant — the menu — would come in for some 21st century marketing treatment.



It’s official — teens can’t stay off social media for more than 15 minutes. It’s no secret that many kids aged between 8 and 18 spend most of their time texting, tweeting and checking their real-time social status. The profound psychological and sociological consequences of this behavior will only start to become apparent ten to fifteen year from now. In the meantime, researchers are finding a general degradation in kids’ memory skills from using social media and multi-tasking while studying.
