These digestible “robots” can be packed into a pill casing and swallowed like any old aspirin.
Meet the future of medical robotics.
Silicon Valley, or the Greater Bay Area, is the 18th largest economy in the world, more than half the size of Canada’s economy and bigger than Switzerland, Saudi Arabia or Turkey. This is because the region has become the world leader in research and development of emerging technologies such as artificial intelligence, robotics, software and virtual reality.
“Software is eating the world,” said Silicon Valley investor Marc Andreessen famously in 2011. It was controversial but prescient.
Five years later, software-driven machines and drones perform surgery, write news stories, compose music, translate, analyze, wage war, guard, listen, speak and entertain. The world’s biggest box office hits — animated films such as “Frozen” or special effects in Hollywood blockbusters like “Star Wars” — are made using software.
In people with Alzheimer’s disease, a new investigational drug can dramatically reduce the amount of amyloid beta plaque, the tangled clumps of proteins that form in the brains of Alzheimer’s patients, according to a new early study of the drug.
The drug works by spurring the immune system to recognize and clear the plaques.
“We believe that’s a hint of efficacy,” study co-author Dr. Alfred Sandrock, a neurologist and an executive vice president at Biogen, said during a news briefing. “We believe that needs to be confirmed with further studies.” Biogen is the Cambridge, Massachusetts, company that funded the trial and applied to patent the drug.

A new technique uses the curious physical laws of the nano-scale itself to “program” nanobots. Welcome to the future of nanotechnology.
Nanorobotics has long been touted as one of the most promising “miracle technologies” of the future. But one of the fundamental problems with such extreme miniaturization is how to “program” nanobots—after all, you can’t very well shrink computer circuitry to fit within nanometer-scale technology.
But now, two researchers, Joseph Wang of UC San Diego and Jennifer Balazs of the University of Pittsburgh, may have found an ingenious way to circumvent this problem. Forget computer controls and artificial intelligence programming—let the laws of physics at the nano-scale do all the programming for you.
In a study published in Nature Medicine, researchers report that they have successfully coaxed stem cell-derived neurons to regenerate lost tissue in damaged corticospinal tracts of rats.
Stem cells are an amazing part of medical research. Because of their ability to become virtually any cell in the human body, they could hold the cure for many varied and grave diseases—from bones, to sight, to memory and thinking, stem cells could help us correct a host of conditions.
In fact, it seems that stem cells might be the key to repairing spinal cord injuries.
Other than speeding up bone healing, slowing Alzheimer’s in mice, ultrasound has been found to help with speedy wound healing. Ultrasound application can help diabetic patients, who suffer from helping defects, up to 30% to decrease the healing time of wounds.
These type of sound waves, trigger a protein pathway essential for fibroblast cells to work. Fibroblast cells help in blood clotting. The number and speed of blood clotting cells are increased in the area of the wound, and the healing process begins. This technique could lower the instances of amputation in case of chronic healing defects in diabetic patients.

There is a stark contrast between the cover stories in current issue of Boys’ Life –vs- Girls’ Life. [see it here]. The Boys cover effectively urges males to learn, build, think and question assumptions. But, the Girls cover wonders “Oh My! What will you do with your hair and nails today!”
Although I am a feminist—and readily jarred by the juxtaposition of contrary messages—I am giving editors at Girls’ Life a ‘get out of jail’ pass this time. It may not be the sexism that it seems.
Jennifer Wright (@JenAshleyWright) kicked up a firestorm last week, when she tweeted a photo of two side-by-side magazines on a newsstand. The contrast between cover features of Boy’s Life –vs- Girl’s Life is startling. With characteristic sarcastic wit, she tweeted:
“Why are you feminists always complaining?
We treat boys and girls exactly the same.”
For those who are reading without the above image, the current issue of these magazines calls out to readers like this:
The difference between these covers suggests that the respective magazine editors are pushing 19th century aspirations onto the next generation of 21st century women. It’s a reminder of lingering differences in the way we perceive the sexes. But does this contrast present a fair and balanced comparison?
Certainly, there is work to do—but, the stark difference between these magazine covers may not point to a societal ill in the way that seems to jump off the screen.
If you tell me that there are plenty of girls that hope to build or fly a jet fighter, I will nod in violent agreement. But if you tell me that there is an equal fraction of boys who obsess over their nails, hair and the color of a blouse, I will wonder if we live on the same planet.
My teenage daughter is clearly in the former group: She imagines, asks tough questions, builds, tears down, and then builds a better gizmo from scratch. She codes Android apps and creates massive murals for the local shopping mall. But, some girls care about classic ‘girly’ things, at least during their early years. And here’s a surprise…
Many of these gilrly girls exhibit just as much technical proficiency and self-confidence as their empowered peers. They are assertive, independent, financially savvy, and aware of their equal political and career footings. Yet, many of us feminists bristle at the thought of a female child who obsesses about their hair and nails (at least to the point of subscribing to a magazine in that venue). In fact, the two are not mutually exclusive.
So, can I still call myself a feminist in the mold of Betty Friedan or Gloria Steinem? Perhaps not. I am more likely to identify with a less militant Helen Gurley Brown. She was all about empowerment and sexual equality. Yet, somehow, she avoided pushing the sexes to be completely indistinguishable and androgynous.
Do you disagree? Do you think that I exhibit a Luddite attitude that is at the core of a chauvinistic society? Don’t just let it grate on you—Be a Wild Duck! Leave a comment here, next to the original article.
