(Phys.org)—Scientists have built a battery containing a magnetic fluid that can be moved in any direction by applying a magnetic field. The magnetically controlled battery concept could be especially useful for flow batteries, where it could eliminate the need for the pumps that are typically required for moving the electrolyte from an external storage tank to the inside of a power stack to provide electricity. Flow batteries are being actively researched as large-scale energy storage devices for power grids, where they could store energy captured by intermittent alternative energy sources such as wind and solar.

The researchers, led by Yi Cui, Professor at Stanford University, have published a paper on the new magnetically controlled battery in a recent issue of Nano Letters.

“The greatest significance of our work lies in the innovative idea of using a magnetic field to control and enhance the mass and electron transport in a battery system,” lead author Weiyang Li, previously at Stanford University and now at Dartmouth College, told Phys.org.

Organovo_LogoOrganovo is one of the most fascinating companies that we follow–and quite continually–as the dynamic company has kept the momentum rolling with one scientific breakthrough after another.

Famous for the design and creation of functional human tissues for medical applications, we’ve recently also been following Organovo and other partnerships in researching human tissue as well as offering the first 3D bioprinted liver product.

It’s just been recently announced that Uniquest signed a worldwide licensing agreement with Organovo to patent kidney cells from induced pluripotent stem cells (iPSCs). Professor Melissa Little and her team at Uniquest have actually been able to grow kidney tissue which should prove to be helpful in not only drug screening but also disease modeling and cell therapy.

Fear of scientists “playing god” is at the centre of many a plot line in science fiction stories. Perhaps the latest popular iteration of the story we all love is Jurassic World (2015), a film I find interesting only for the tribute it paid to the original Michael Crichton novel and movie Jurassic Park.

Full op-ed from h+ Magazine on 7 October 2015 http://hplusmagazine.com/2015/10/07/opinion-synthetic-biolog…f-mankind/

john hammond jurrasic parkIn Jurassic Park, a novel devoted to the scare of genetic engineering when biotech was new in the 1990s, the character of John Hammond says:

“Would you make products to help mankind, to fight illness and disease? Dear me, no. That’s a terrible idea. A very poor use of new technology. Personally, I would never help mankind.”

What the character is referring to is the lack of profit in actually curing diseases and solving human needs, and the controversy courted just by trying to get involved in such development. The goal to eradicate poverty or close the wealth gap between rich and poor nations offers no incentive for a commercial company.

Instead, businesses occupy themselves with creating entertainment, glamour products and perfume, new pets, and other superfluities that biotech can inevitably offer. This way, the companies escape not only moral chastisement for failing to share their technology adequately or make it freely available, but they can also attach whatever price tag they want without fear of controversy.

It is difficult for a well-meaning scientist or engineer to push society towards greater freedom and equality in a single country. It is even harder for such a professional to effect a great change over the whole world or improve the human condition the way transhumanists, for example, have intended.

Although discovery and invention continue to stun us all on an almost daily basis, such things do not happen as quickly or in as utilitarian a way as they should. And this lack of progress is deliberate. As the agenda is driven by businessmen who adhere to the times they live in, driven more by the desire for wealth and status than helping mankind, the goal of endless profit directly blocks the path to abolish scarcity, illness and death.

Today, J. Craig Venter’s great discoveries of how to sequence or synthesize entire genomes of living biological specimens in the field of synthetic biology (synthbio) represent a greater power than the hydrogen bomb. It is a power we must embrace. In my opinion, these discoveries are certainly more capable of transforming civilization and the globe for the better. In Life at the Speed of Light(2013), that is essentially Venter’s own thesis.

And contrary to science fiction films, the only threat from biotech is that humans will not adequately and quickly use it. Business leaders are far more interested in profiting from people’s desire for petty products, entertainment and glamour than curing cancer or creating unlimited resources to feed civilization. But who can blame them? It is far too risky for someone in their position to commit to philanthropy than to stay a step ahead of their competitors.

Even businessmen who later go into philanthropy do very little other than court attention in the press and polish the progressive image of the company. Of course, transitory deeds like giving food or clean water to Africans will never actually count as developing civilization and improving life on Earth, when there are far greater actions that can be taken instead.

It is conspicuous that so little has been done to develop the industrial might of poor countries, where schoolchildren must still live and study without even a roof over their heads. For all the unimaginable destruction that our governments and their corporate sponsors unleash on poor countries with bombs or sanctions when they are deemed to be threatening, we see almost no good being done with the same scientific muscle in poor countries. Philanthropists are friendly to the cause of handing out food or money to a few hungry people, but say nothing of giving the world’s poor the ability to possess their own natural resources and their own industries.

Like our bodies, our planet is no longer a sufficient vehicle for human dreams and aspirations. The biology of the planet is too inefficient to support the current growth of the human population. We face the prospect of eventually perishing as a species if we cannot repair our species’ oft-omitted disagreements with nature over issues of sustainability, congenital illness and our refusal to submit to the cruelties of natural selection from which we evolved.

Once we recognize that the current species are flawed, we will see that only by designing and introducing new species can suffering, poverty and the depletion of natural resources be stopped. Once we look at this option, we find already a perfect and ultimately moral solution to the threats of climate change, disease, overpopulation and the terrible scarcity giving rise to endless injustice and retaliatory terrorism.

The perfect solution could only be brought to the world by a heroic worker in the fields of biotech and synthetic biology. Indeed, this revolution may already be possible today, but fear is sadly holding back the one who could make it happen.

Someone who believes in changing the human animal with technology must believe in eradicating poverty, sickness and injustice with technology. For all our talk of equality and human rights in our rhetoric, the West seems determined to prevent poorer countries from possessing their own natural resources. A right guaranteed by the principles of modernization and industrialization, which appears to have been forgotten. Instead, we prefer to watch them being nursed by the richer countries’ monopolies, technology, and workers who are there cultivating, extracting, refining, or buying all their resources for them.

So, quite contrary to the promises of modernity, we have replaced the ideal of the industrialization of poor states with instead the vision of refugee camps, crude water wells, and food aid delivered by humanitarian workers to provide only temporary relief. In place of a model of development that was altruistic and morally correct, we instead glorify the image of non-Westerners as primitives who are impossible to help yet still we try.

The world’s poor have become not the focus of attention aimed at helping humanity, but props for philanthropists to make themselves look noble while doing nothing to truly help them. What we should turn to is not a return to the failed UN development agendas of the 1970s, which were flawed, but a new model entirely, and driven by people instead of governments and UN agencies.

It is high time that we act to help mankind altruistically, rather than a select few customers. The engineers and scientists of the world need to abandon the search for profit, if only for a moment. We should call on them to turn their extraordinary talent to the absolute good of abolishing poverty and scarcity. If they do not do this, we will talk about direct action to break free the scientific gifts they refused to share.

We live in courageous times. These are times of whistle-blowers, lone activists for the truth, and lone scientist-entrepreneurs who must be praised even if our profit-driven culture stifles their great works. And although we live in courageous times, we seem not yet brave enough to take real action to overcome the human disaster.

Liposome was observed through a narrow-band blue excitation filter (suitable for SYBR Green). (E) Same as previously with a wideband green excitation filter (suitable for DiI). Because of a low fluorescence response, part D was digitally enhanced in terms of brightness and contrast. In comparison, part E was darkened to present a level similar to part D. These pictures were taken at an interval of ~1 s, just the time to switch the filters. (E) Fluorescence picture of λ-DNA-loaded liposomes. Green dots stand for λ-DNA molecules, and lipids are labeled in red. A wideband blue excitation filter was used for this bicolor imaging, and a high-sensitivity color CCD camera captured it. [Anal.

Treating cancer by boosting the immune system has been hailed as a major breakthrough in cancer treatment. It may melt away tumours in some patients but it isn’t always effective, and can even be dangerous.

The FDA approved two new immunotherapy drugs in 2015, and over half current cancer trials now involve immunotherapy. The field has the potential to completely change cancer treatment, but it’s still early days.

Have you hugged or told someone that you love them today? Maybe it wasn’t someone — maybe it was your smartphone that you gave an extra squeeze or gave an extra pat as you slipped it into your pocket. Humans have become increasingly invested in their devices, and a new era of emotional attachment to our devices and other AI seems to be upon us. But how does this work itself out on the other end — will or could AI ever respond to humans in an emotional fashion?

Communication Sparks Emotional Response

AI is broad, and clearly not all AI are meant to give and receive in an emotional capacity. Humans seem prone to respond to features that are similar to its own species, or to those to which it can relate to in some sort of communicative way. Most “emotional” or responsive algorithm-based capabilities have been programmed into robots that are in a humanoid – or at least a mammal-like – form.

Think androids in customer-service, entertainment, or companion-type roles. There are also robots like PARO, the baby harbor seal used for therapeutic interaction with those in assisted living and hospital environments.

In a 2003 paper published through the International Journal of Human-Computer Studies, Cynthia Breazeal quotes a study by Reeves and Nass (1996), whose research shows humans (whether computer experts, lay people, or computer critics) generally treat computers as they might treat other people.

Breazeal goes on to state that humanoid robots (and animated software agents) are particularly relevant, as a similar morphology promotes an intuitive bond based on similar communication modes, such as facial expression, body posture, gesture, gaze direction, and voice.

An Emotional Model for AI

This in and of itself may not be a complete revelation, but how you get a robot to accomplish such emotional responses is far more complicated. When the Hanson Robotics’ team programs responses, a key objective is to build robots that are expressive and lifelike so that people can interact and feel comfortable with the emotional responses that they are receiving from a robot.

In the realm of emotions, there is a difference between robot ‘responses’ and robot ‘propensities’. Stephan Vladimir Bugaj, Creative Director at Hanson Robotics, separated the two during an interview with TechEmergence. “Propensities are much more interesting and are definitely more of the direction we’re going in the immediate long-term”, he says.

“An emotional model for a robot would be more along the lines of weighted sets of possible response spaces that the robot can go into based on a stimulus and choose a means of expression within that emotional space based on a bunch of factors.” In other words, a robot with propensities would consider a set of questions, such as “What do I think of the person? How did it act in the last minute? How am I feeling today?”. This how most humans function through reason, though it happens so habitually and quickly in the subconscious that we are hardly aware of the process.

Context of immediate stimulus would provide an emotional frame, allowing a robot to have a more complex response to each stimulus. The use of short-term memory would help the robot build a longer-term emotional model. “You think of it as layers, you can think of it as interconnected networks of weighted responses…as collections of neurons, there’s a lot of different ways of looking at it, but it basically comes down to stages of filtering and considering stimuli, starting with the input filter at the perceptual level.”

Similar to a human being, robots could have more than one response to a stimulus. An initial reaction or reflex might quickly give way to a more “considered response”, cause by stored and shared information in a neural-like network. Stephan describes a hypothetical scene in which a friend enters a room and begins taking swings at his or her friend. At first, the friend who is on the defense might react by immediately assuming a fighting stance; however, it might only take a few seconds for him or to realize that the other person is actually just “horsing around” and being a bit of an antagonist for sport.

This string of events provides a simple way to visualize emotional stages of reaction. Perception, context, and analysis all play a part in the responses of a complex entity, including advanced robots. Robots with such potential complex emotional models seem different from AI entities programmed to respond to human emotions.

The Beginnings of Responsive Robots

These AI don’t necessarily need to take a human-like form (I’m thinking of the movie Her), as long as they can communicate in a language that humans understand. In the past few years, innovators have started to hit the IndieGogo market with domestic social robots such as Jibo and EmoSPARK, meant to enhance human wellbeing through intelligent response capabilities.

Patrick Levy Rosenthal, founder of EmoSpace, envisioned a device that connects to the various electronic objects in our homes, able to adjust their function to positively affect our emotional state. “For the last 20 years, I believe that robotics and artificial intelligence failed humans…we still see them as a bunch of silicon… we know that they don’t understand what we feel.”

Rosenthal set out to change this perception with EmoSPARK, a cube-like AI that calibrates with other objects in the user’s home, such as an mp3 music player. The device, according to Rosenthal, tracks over 180 points on a person’s face, as well as the relation between those points – if you’re smiling, your lips will be stretched and eyes more narrow. The device also detects movement and voice tonality for reading emotional cues. It can then respond to those cues with spoken prompts and suggestions for improving mood – for example, asking if its human user needs to hear a joke or a favorite song; it can also respond to and process spoken commands.

While robots that respond to humans’ emotionally-based states and requests may soon be available to the masses, robots that have their own emotional models – that can “laugh and cry” autonomously, so to speak – are still out of reach, for the time being.
