A rapid, accurate test that can detect biomarkers of lung cancer in saliva is soon to be trialed in patients.
The news marks a milestone in over 10 years of research led by oral cancer and saliva diagnostics researcher Prof. David Wong, of the School of Dentistry at the University of California-Los Angeles (UCLA).
Prof. Wong and colleagues have been working on a method called “liquid biopsy” that detects circulating tumor DNA in bodily fluids such as saliva and blood.
Liquid biopsy holds the promise of rapid, less invasive identification of cancers and easier tracking of disease progress during treatment.
Prof. Wong described the prototype in a news briefing at the 2016 Annual Meeting of the American Association for the Advancement of Science (AAAS), which is taking place in Washington, DC.
The device uses electric field-induced release and measurement (EFIRM) to detect non-small cell lung cancer (NSCLC) biomarkers in saliva.
The EFIRM device analyzes the contents of exosomes – tiny bags of molecules that cells release now and again. The device forces the exosomes to release their contents and carries out bio-recognition of the released biomolecules at the same time.
High accuracy compared with current sequencing technology
In a study published in 2013, Prof. Wong and colleagues described using EFIRM to show that saliva contains tumor-shed exosomes, which have previously been found in blood.
The approach has a high accuracy compared with current sequencing technology, says Prof. Wong, explaining that the trial in lung cancer patients is taking place in China this year. The study is a collaboration between UCLA and West China Hospital of Sichuan University.
Prof. Wong says the test takes only 10 minutes to give a result and could be done in the doctor’s office.
He sees it forming part of a set of diagnostic tools. For example, should a lung X-ray show a suspicious nodule, then the doctor could use the saliva test to rapidly find out if cancer is likely.
The test works by detecting genetic mutations in a protein called epidermal growth factor receptor (EGFR). The protein normally helps cells grow and divide, but some NSCLC cells have too much EGFR, which makes them grow faster. Drugs called EGFR inhibitors that block the protein could be ordered promptly by a clinician.
Prof. Wong and colleagues have also been looking at the possibility of a saliva test for detecting mutations linked to oropharyngeal cancers – cancers of the mouth and the back of the throat.
Gypsyamber D’Souza, associate professor of epidemiology at the Johns Hopkins University Bloomberg School of Public Health, Baltimore, MD, was also at the news briefing with Prof. Wong. She says enthusiasm for the liquid biopsy must be tempered by the complexity of the cancer process and the potential usefulness of the technique for specific cancers.
Prof. Wong’s announcement follows a recent Medical News Today report about the development of a salivary gland test for early Parkinson’s disease. The test, which uses a biopsy of gland tissue, could provide an accurate and timely diagnosis of a disease for which there is currently no way to detect in its early stages.
One of the drawbacks of DNA aptamers – synthetic small molecules that show promise for detecting and treating cancer and other diseases – is they do not bind readily to their targets and are easily digested by enzymes in the body. Now, scientists have found a way to produce DNA aptamers without these disadvantages.
The team – from the Institute of Bioengineering and Nanotechnology (IBN) at Agency for Science, Technology and Research (A*STAR) in Singapore – describes how they developed and tested the improved DNA technology in the journal Scientific Reports.
IBN Executive Director Prof. Jackie Y. Ying says the team created “a DNA aptamer with strong binding ability and stability with superior efficacy,” and:”We hope to use our DNA aptamers as the platform technology for diagnostics and new drug development.”
Aptamers are a special class of synthetic ribonucleic acid (RNA) or deoxyribonucleic acid (DNA) molecules that are showing promise for clinical use.
These small molecules could be ideal for drug applications because they can be made for highly specific targets – such as proteins, viruses, bacteria and cells.
Drawbacks of current DNA aptamers
Once aptamers are engineered for a specific target, they bind to it and block its activity.
They are the chemical equivalent of antibodies, except, unlike the antibodies currently used in drug development, they do not cause undesirable immune responses and could be easier to mass produce at high quality.
The first aptamer-based drug – an RNA aptamer for the treatment of age-related macular degeneration (AMD) – was approved in the US in 2004, and several other aptamers are currently being evaluated in clinical trials.
However, no DNA aptamer has yet been approved for clinical use because the ones currently developed do not bind well to molecular targets and are easily digested in the bloodstream by enzymes called nucleases.
In their paper, lead author Dr. Ichiro Hirao, a principal research scientist at IBN, and colleagues describe how they overcame these two problems.
‘Unnatural base’ and ‘mini-hairpin’ remove DNA aptamer disadvantages
To overcome the problem of weak binding, the team added a new artificial component – called an “unnatural base” – to a standard DNA aptamer, which typically has four components.
The paper describes how the addition of a fifth unnatural base component to the DNA aptamer strengthened its binding ability by 100 times.
To prevent the aptamer from being easily digested by enzymes, the team added a small piece of DNA that they call a “mini-hairpin DNA.”
Dr. Hirao says mini-hairpin DNAs are made of small DNA fragments that form a compact, stem-loop structure, like a hairpin, and this is what makes them stable.
Typically, DNA aptamers do not last longer than an hour in blood at room temperature because they are broken down by nucleases. But the team found the addition of the mini-hairpin DNA could help DNA aptamers survive for days – making them more appealing for drug development.
In their paper, the scientists describe how their modifications improved a DNA aptamer that targets a cell-signaling protein called interferon gamma.
Lab tests showed the improved aptamer survived in human blood at 37 °C after 3 days and “sustainably inhibited the biological activity” of interferon gamma, note the authors.
Dr. Hirao says their modifications show it is possible to generate DNA aptamers with great promise for clinical use: they are potentially more effective in their action, cheaper to produce and have fewer adverse side effects than conventional methods. He concludes:”The next step of our research is to use the aptamers to detect and deactivate target molecules and cells that cause infectious diseases, such as dengue, malaria and methicillin-resistant Staphylococcus aureus (MRSA), as well as cancer.”
In December 2015, Medical News Today learned how researchers from the University of Texas at Arlington are developing a way to detect cancer cells using electronic chips coated with RNA aptamers. The team hopes it will lead to a tabletop tool that offers doctors cheaper and faster tests for disease prediction.
A new study, published in Neurology, finds plaques in the brains of middle-aged people who have experienced head injuries. These amyloid plaques match those found in Alzheimer’s, but their spatial distribution differs.
According to an editorial that is published alongside the present research, visitors to the emergency department for traumatic brain injuries (TBI) have risen 70% in the last 10 years.
Today, between 2 and 5 million Americans are estimated to live with a TBI-related disability.
According to the National Institute of Neurological Disorders and Stroke, a TBI occurs:
“When a sudden trauma causes damage to the brain.”
TBIs can be generated in any number of ways, from a sporting incident to a workplace calamity. They are caused when the head strikes a solid mass, or by an object penetrating the skull.
The impact of brain injuries
Individuals who experience a TBI can have a multitude of medical issues, varying in gravity. Prognosis depends on a number of factors, including the severity of the injury, where in the brain the impact occurs and the age of the patient.
Around half of TBIs will require surgery to repair ruptured blood vessels or bruised brain tissue. Some individuals will face cognitive problems or difficulties processing sensory information. Others still might have difficulty communicating or display mental health issues such as anxiety or depression.
Another long-term risk for TBI patients is dementia. The mechanisms behind this relationship are unclear, but the current research makes some headway into understanding how this might occur.
Brain injury and Alzheimer’s
Researchers at Imperial College London in the UK, led by Prof. David Sharp, took an in-depth look at the brains of middle-aged individuals who had suffered a TBI.
The study took brain scans of nine individuals with moderate to severe TBIs. The average age of the group was 44, and their brain injuries had occurred between 11 months and 17 years previously.
The researchers utilized two types of scan: PET scans (positron emission tomography) and MRI scans (magnetic resonance imaging). The PET scans detected amyloid plaques in the brain and the MRI scans searched out evidence of cellular damage resulting from the trauma.
The TBI group’s scans were compared with 10 people with Alzheimer’s and 9 healthy control subjects. Commenting on the results, Prof. Sharp says:
“The areas of the brain affected by plaques overlapped those areas affected in Alzheimer’s disease, but other areas were involved. It suggests that plaques are triggered by a different mechanism after a traumatic brain injury. The damage to the brain’s white matter at the time of the injury may act as a trigger for plaque production.”
The team found that both the Alzheimer’s and the brain injury groups had amyloid plaques in the posterior cingulate cortex. This highly connected and metabolically active brain region is known to be involved in the early stages of Alzheimer’s progression.
Interestingly, the TBI group, but not the Alzheimer’s group, also showed plaques in the cerebellum.
Future research possibilities
To date, medications for Alzheimer’s can only minimize certain symptoms and slow its progression. This is not adequate; hundreds of research teams are investigating better solutions on a global scale.
A vital aspect of Alzheimer’s research is the creation of reliable animal models. Medical News Today recently asked Dr. Gregory Scott, the study’s first author, whether his research could be useful in this regard:
“Potentially, however, a well-established challenge is that many animals do not generate amyloid in the same way as humans after a brain trauma. As you say, there are already animal models of Alzheimer’s disease, of course, and in fact we are involved in a study looking at TBI in animal models of Alzheimer’s disease.”
The team cautiously notes that the current study is a relatively small-scale trial, however, Prof. Sharp holds out hope that it could lead to more. He believes that if a substantial link can be found between brain injury and the onset of Alzheimer’s disease, it might help neurologists uncover treatment and prevention strategies to reduce the progression of Alzheimer’s at an earlier stage.
When asked about future research, Dr. Scott told MNT that he is currently looking at novel ways to reduce inflammation after TBI, and investigating the relationship between brain inflammation and white matter damage:
“We have completed another PET study recently looking at neuroinflammation after TBI and the effect of the antibiotic minocycline on the signal. We are also looking at other biomarkers of chronic injury.”
TBIs can be serious and life-changing events. Research will, no doubt, lead to significant improvements in the way brain injury is treated. MNT recently covered research that found a link between ADHD and traumatic brain injury.
Proton therapy is as effective as standard photon or X-ray radiotherapy at treating the most common type of malignant brain tumor in children – and causes fewer long-term side effects.
This was the conclusion of a trial led by Massachusetts General Hospital (MGH) in Boston and published in The Lancet Oncology.
Lead and corresponding author Torunn Yock – director of pediatric radiation oncology at MGH, and an associate professor of radiation oncology at Harvard Medical School in Boston, MA – says:
“Our results indicate that proton therapy maintains excellent cure rates in pediatric medulloblastoma while reducing long-term side effects, particularly in hearing and neurocognitive function, and eliminating cardiac, pulmonary, gastrointestinal and reproductive effects.”
Medulloblastoma is a fast-growing brain tumor that occurs mostly in children and accounts for 18% of childhood brain tumors. It develops in the cerebellum at the base of the brain.
In most cases, medulloblastoma can be treated successfully with a combination of surgery, chemotherapy and radiotherapy, but because of its position in the brain, the treatment often results in long-term side effects.
Less collateral damage to healthy tissue
The aim of radiotherapy is to kill all malignant cells to eliminate the tumor and stop it growing back. While conventional photon radiotherapy based on X-rays can do this, there is a high risk of collateral damage because the beam – although it is directed at the tumor – also delivers radiation to tissue in front and behind it.
Such damage may not make a big difference if there is plenty of surrounding tissue whose loss does not impair function. But in the brain – particularly in the brain of a child – every tiny bit of healthy tissue counts and any loss is more likely to impair important functions.
Proton therapy – also known as proton beam therapy – uses a proton beam, with which it is possible to more precisely confine radiation to the tumor. The result is a much smaller chance of killing healthy surrounding tissue.
The following video from IBA – a company that manufactures medical devices for cancer treatment – explains how proton beam therapy works:
Prof. Yock explains that although proton therapy is still not widely available in the US and other countries, more and more doctors value its potential for reducing treatment side effects, particularly in children, and at “experienced centers,” she notes, “proton therapy has a proven track record of treatment success and safety.”
However, while proton therapy is valued because it appears to reduce adverse side effects, the authors note that nobody had actually done a long-term follow-up of children treated for medulloblastoma with proton therapy.
So for their trial, the team enrolled 59 patients of average age 6.5 years – ranging from 3-21 – who underwent proton therapy for medulloblastoma at the MGH between 2003-2009 following surgery to remove as much of the tumor as possible. All patients had also received chemotherapy before, during or after proton therapy.
At the start of the study and at follow-up visits, the investigators measured the patients’ hearing, mental function, hormone levels, height and weight. Thirteen patients died over the follow-up, which lasted up to 8 years.
Survival rates similar, but side effects reduced
When they analyzed the results, the researchers found that survival rates and the incidence and type of tumor recurrence were similar for the proton therapy patients to what has been reported for photon radiotherapy in other studies.
However, there were reductions in side effects. For example, 3 years after treatment, 12% of patients had significant hearing loss, and this proportion increased to 16% at 5 years. These figures compare favorably with the 25% reported in studies using photon radiotherapy, the authors note.
The impact of proton therapy on some mental functions – such as verbal comprehension and processing speed – was also less serious than that reported with photon radiotherapy. The authors note that these effects occurred primarily in children who were 8 years old or under when they received proton therapy.
Effects on hormone levels were comparable to what has been reported with photon therapy, with 63% of patients showing deficits in any hormones 7 years after treatment.
But a significant result is the absence of any heart, lung, intestinal, seizure or secondary tumor effects in the proton therapy patients. All these side effects have been reported in photon therapy studies.
The authors conclude that because their findings show proton radiotherapy has “acceptable toxicity” and has similar survival outcomes to conventional radiotherapy, it could be an alternative to photon-based treatments.
The team is now studying the quality-of-life differences between proton and photon treatment, but Prof. Yock nonetheless says:
“I truly believe that – particularly for the youngest children – the ability to offer them proton therapy can make a big difference in their lives.”
Magic Leap has been successful in keeping a lot of its technology under wraps — the augmented and virtual reality technology company has yet to release a product — but its fundraising has been an open secret. Today, however, one part of it is finally being confirmed: the startup announced that it has raised $793.5 million in a Series C round of funding, at a valuation that a spokesperson tells us was $3.7 billion pre-money, and $4.5 billion post-money.
That’s right: a $4.5 billion valuation, with a commercial product yet to launch.
This latest investment was led by China’s e-commerce powerhouse Alibaba, with participation also from existing investors Google and Qualcomm Ventures. Other new investors in this round are a who’s-who of finance with a little dose of entertainment: they include Warner Bros, Fidelity, J.P. Morgan, Morgan Stanley, T. Rowe Price and Wellington Management Co. (Am I the only one surprised that Disney is not even partly involved?)
Today’s announcement doesn’t give us any peek into when we might finally see a product launch from the company — we are asking the question, though. What we do get is a basic description, from the founder of how Magic Leap, of how the startup proposes to fit its tech into the current mix of digital media.
“Here at Magic Leap we are creating a new world where digital and physical realities seamlessly blend together to enable amazing new experiences. This investment will accelerate bringing our new Mixed Reality Lightfield experience to everyone,” said Rony Abovitz, Founder, President, and CEO of Magic Leap, Inc. in a statement. “We are excited to welcome Alibaba as a strategic partner to help introduce Magic Leap’s breakthrough products to the over 400 million people on Alibaba’s platforms.”
As part of the round, Alibaba’s Joe Tsai will join Magic Leap’s board.
“We invest in forward-thinking, innovative companies like Magic Leap that are developing leading products and technologies,” said Joe Tsai, Executive Vice Chairman at Alibaba. “We believe Alibaba can both provide support to and learn from such a partner, and we look forward to working with the Magic Leap team.”
The Alibaba participation, apart from being financial, seems to me that it could potentially have strategic elements, too: one of the larger barriers for more growth in e-commerce is the disconnect between buying physical items but being unable to see them with your own eyes.
Better AR experiences could be one way of giving people a closer look at what they are buying in the virtual world — see the video above and imagine that instead of a cute elephant, the object in your hands is a camera, or a piece of jewellery, or a bathing suit that you can subsequently ‘try on’. It could even be used to create virtual “stores” where people could walk along aisles to browse and shop as they do in the real, physical world.
If the funding sounds insane — especially in today’s climate where some of the most promising tech startups are getting marked down, and we hear many canaries telling us that there is more to come — from what I understand, there is a method to this madness.
Magic Leap has already been working for years on its technology. That work is not just about writing code, but about processing power and essentially creating completely new environments to develop and test what is being developed. It’s probably still a gamble, and as with all else in tech at some point what costs a fortune will drop drastically in price, but for now this is the price of entry for something that holds the promise of being transformational — or so the thinking goes.
Other investors in the company include Legendary Entertainment, KKR, Vulcan Capital, Kleiner Perkins Caufield & Byers, Andreessen Horowitz, Obvious Ventures, and others. Prior to this round, Magic Leap had raised $592 million.
A large and international meeting on the ethics of human-genome editing is poised to begin — and researchers are curious about how perceived differences in attitudes will play out.
“We’re hoping to sort of take the temperature of the world,” says David Baltimore, the virologist at the California Institute of Technology in Pasadena who is chairing the International Summit on Human Gene Editing. It runs 1–3 December in Washington DC.
Jointly organized by the US National Academy of Sciences, the US National Academy of Medicine, the Chinese Academy of Sciences and the UK Royal Society, the meeting is expected to draw representatives from more than 20 countries, including India, Sweden and Nigeria.
The popularity of the genome-editing tool CRISPR–Cas9, which uses bacterial enzymes to cut genomes in precise spots to disrupt or repair troublesome genes, has sparked an ethical debate — and many believe that the time is ripe for an international discussion.
In January, Baltimore and a small group of scientists gathered in Napa, California, to discuss issues surrounding genome editing, including rumours that researchers had already edited human embryos. Some consider the editing of any reproductive cell as contentious because the changes could be passed to future generations. Concerns escalated in April, when researchers in China announced that they had edited human embryos — although they had deliberately used non-viable embryos that could not result in a live birth1.
Baltimore and his colleagues then approached Ralph Cicerone, president of the National Academy of Sciences, with the idea of holding an international summit. “Everyone knew that whatever anybody did had to be inherently international,” Cicerone says. “There are really strong efforts in so many countries that could employ this new technology.”
Zhihong Xu, a plant biologist at Peking University who will represent the Chinese Academy of Sciences at the meeting, is curious about whether perceived differences in attitude — in particular between the United States and China — are real. “I believe that this is an issue for all of us to consider seriously together,” he says.
Cicerone hopes that the meeting will illuminate any scientific, ethical and cultural differences in how countries think about genome editing — and perhaps even lead to beginnings of an international consensus on outstanding scientific questions, research priorities and ethical guidelines.
But such a consensus would only be the start of a broader discussion, Cicerone cautions. Eventually the health industry, disease lobby groups, members of the public and governments of the many nations involved, will need to feed into decisions. “As much work as we’ve put into this meeting,” Cicerone says, “it really is only a first big step.”
Doctors might get even better at detecting tumors in breast cancer patients early, thanks to pressure-sensitive rubber gloves that supercharge their sense of touch. But the sensors that power those gloves could be useful in all kinds of non-medical scenarios, too.
Getting a regular exam from your doctor is still one of the most effective ways of catching the signs of breast cancer early, but it’s easy to miss the telltale hardness of a tumor when a rubber surgical glove is involved. That’s why a team of researchers led by Dr. Sungwon Lee and Professor Takao Someya of the University of Tokyo’s Graduate School of Engineering has developed a new type of pressure sensor which is thin and resilient enough to fit into a glove.
Pressure sensors flexible enough to mold themselves to the contours of a human hand have been available for awhile now, but they can’t handle bending, twisting, or wrinkling while still giving accurate measurements. Using organic transistors made of carbon nanontubes, graphene, carbon, and oxygen, the University of Tokyo team was able to address this problem, creating a transparent sensor just 8 micrometers thick—one-fifth the thickness of a human hair—that can measure pressure in 144 places at once. In conjunction with the right software, these sensors could be used in standard surgical gloves to help doctors detect tumors by touch alone.
But according to the team, this same technology has just as much potential for implantable and wearable devices. Sadly, they didn’t go as far as to name them, but it’s easy to imagine the possibilities. Just a few uses that come to mind include a smart tattoo that could also function as a touchpad, touch sensitive clothing that can go through the wash, or pressure-sensing VR gloves as thin as the ones you use to do the dishes that can detect how you’re moving your fingers. Saving lives might be just the start for this technology.
Since the 1950s, virtual reality (VR) has been hovering on the periphery of technology without achieving accepted mainstream application or commercial adoption. Since 2012, VR startups have raised more than $1.46 billion in venture capital, including more than $100 million in funding during the last four consecutive quarters.
According to Citi analyst Kota Ezawa, 2016 is the year that VR will take off in earnest, with the VR market expected to grow to a $15.9 billion industry by 2019. Citi also anticipates the market for hardware, networks, software and content will reach $200 billion by 2020.
The content share of this market is of particular interest, as this segment of the tech industry has historically been dedicated to gaming — but the world is changing. We are shifting from the now relatively benign universe in Aldous Huxley’s Brave New World to Ernest Cline’s VR paradigm as described in Ready Player One. Like Huxley, Cline has written of a dystopian environment wherein technology has overtaken humanity.
For our purpose, let’s consider VR as a useful tool, and perhaps even a productive enhancement to human interaction, bringing together people from around the world to engage and interact — regardless of social, economic or geographic disparities. In the abstract as well as the applied, modern education is poised to take advantage of this latest tech innovation.
Over the last several years, VR has moved from being the purview of the military and aviation to the mainstream of professional development, as managers, instructors, coaches and therapists have claimed increasing benefit from immersive experiences.
While statistics on VR use in K–12 schools and colleges have yet to be gathered, the steady growth of the market is reflected in the surge of companies (including zSpace, Alchemy VR and Immersive VR Education) solely dedicated to providing schools with packaged educational curriculum and content, teacher training and technological tools to support VR–based instruction in the classroom. Myriad articles, studies and conference presentations attest to the great success of 3D immersion and VR technology in hundreds of classrooms in educationally progressive schools and learning labs in the U.S. and Europe.
Perhaps the most utopian application of this technology will be seen in terms of bridging cultures and fostering understanding among young students.
Much of this early foray into VR–based learning has centered on the hard sciences — biology, anatomy, geology and astronomy — as the curricular focus and learning opportunities are notably enriched through interaction with dimensional objects, animals and environments. The World of Comenius project, a biology lesson at a school in the Czech Republic that employed a Leap Motion controller and specially -adapted Oculus Rift DK2 headsets, stands as an exemplary model of innovative scientific learning.
In other areas of education, many classes have used VR tools to collaboratively construct architectural models, recreations of historic or natural sites and other spatial renderings. Instructors also have used VR technology to engage students in topics related to literature, history and economics by offering a deeply immersive sense of place and time, whether historic or evolving.
In what may turn out to be an immersive education game changer, Google launched its Pioneer Expeditions in September 2015. Under this program, thousands of schools around the world are getting — for one day — a kit containing everything a teacher needs to take their class on a virtual trip: Asus smartphones, a tablet for the teacher to direct the tour, a router that allows Expeditions to run without an Internet connection, a library of 100+ virtual trips (from the Great Wall of China to Mars) and Google Cardboard viewers or Mattel View-Masters that turn smartphones into VR headsets.
This global distribution of VR content and access will undoubtedly influence a pedagogical shift as these new technologies allow a literature teacher in Chicago to “take” her students to Verona to look at the setting for Shakespeare’s Romeo and Juliet, or a teacher in the Bronx to “bring” her Ancient Civilizations class to the ancient Mayan ruins at Chichen Itza.
And with VR platforms like AltspaceVR and LectureVR (an initiative of Immersive VR Education), entirely new possibilities are available for teachers of all kinds, as the technology of making avatars and supporting “multi-player” sessions allows for an exponentially- scaled level of socialization and outreach.
Potentially, a collaboration between these innovative VR platform offerings could result in a curator or artist guiding a group of thousands around a museum exhibition or cultural site, or an actor or professor leading a virtual master class in real time with students from all over the world.
Perhaps the most utopian application of this technology will be seen in terms of bridging cultures and fostering understanding among young students, as it will soon be possible for a third-grade class in the U.S. to participate in a virtual trip with a third-grade class in India or Mexico.
Access to some type of mobile VR device is affordable for many more individual users and, in turn, many more schools.
Despite the fact that VR is still developing, real progress has been seen in the economic scaling of the technology. The cost to the consumer of VR hardware (headsets, in particular) has steadily declined, as noted in the head–mounted displays (HMDs) commercially available today: Google Cardboard for $20 and Samsung Gear VR for $99 (at this writing, Oculus Rift, a desktop VR device, is available for pre–order for $599).
The fact that The New York Times recently supplied more than one million subscribers with Google Cardboard headsets to access its newly launched VR experiences has further advanced accessibility and mainstreaming of the device, as well as this innovative means of media consumption.
Overall, access to some type of mobile VR device is affordable for many more individual users and, in turn, many more schools. Some forward-thinking instructors are even using 3D printers to print their own customized HMDs with their technology students, a solution that dovetails with the popular maker–trend philosophy.
So maybe we are ready for the futuristic world of Cline’s Ready Player One. But perhaps the utopian rather than dystopian construct is not only more appealing, but also more relevant in this global community.
Educators and students alike are seeking an ever-expanding immersive landscape, where students engage with teachers and each other in transformative experiences through a wide spectrum of interactive resources. In this educational reality, VR has a definitive place of value.
With all of the declarations of augmented reality and virtual reality’s inevitable ascents to the heights of technological cruciality, Apple has managed to stay noticeably quiet on the topic. This has led to any VR/AR movement on their end being quite notable.
According to a report from the Financial Times, Apple just hired a top AR/VR specialist to join their team. Doug Bowman, a man who quite literally wrote the book on 3D interfaces (he was the lead author of 3D User Interfaces: Theory and Practice), will be joining the Cupertino-based tech giant following a sabbatical from his position as a professor of Computer Science and the Director of the Center for Human-Computer Interaction at Virginia Tech. He also served as the general chair of the IEEE Virtual Reality Conference in 2007-2008 according to his Virginia Tech bio.
Bowman, who has been employed by Virginia Tech since 1999, has published and collaborated on numerous articles relating to augmented reality and virtual reality including, “Virtual Reality: How Much Immersion Is Enough?,” “3D User Interfaces: New Directions and Perspectives,” and “The Effects of Visual Realism on Search Tasks in Mixed Reality Simulation.”
A particularly interesting tidbit from the FT’s report involves his being the recipient of one of the first $100,000 HoloLens research grants from Microsoft for a study on “collaborative analysis of large-scale mixed reality data.”
A quick scour of his CV indicates a laundry list of impressive accomplishments in the field of AR/VR research that will undoubtedly prove useful to Apple which has, in the very least, indicated interest in the AR/VR space. He also details that his research interests include three-dimensional user interfaces, virtual environments, virtual reality, augmented reality and human-computer interaction.
Unlike its competitors, including Google, Facebook (Oculus), Samsung and HTC, Apple has yet to formally announce any serious hardware or software efforts in the virtual/augmented reality field, though patent applications and their 360-degree videos certainly show that they’ve been experimenting with it. Positing what AR/VR pursuits could be next for Apple would just be simple speculation, but it will certainly be interesting to see what comes of hires like this in the future.
The virtual fire continues to heat up beneath the AR/VR industry with investments continuing to build and soar. According to a report from Digi-Capital, AR and VR investments are taking off pretty rapidly with nearly $700 million being invested into the space in 2015.
The overall trends show investment steadily rising. The report notes that there “have now been 6 straight quarters of AR/VR investment growth, with a quarter of a billion dollars invested in Q4 2015 alone at nearly 6x the rate of mid-2014.”
The report also detailed that 2015 saw just $311 million of AR/VR M&A exits, which it noted wasn’t all that surprising given how relatively early it is in the industry’s life cycle. The report stressed that there would likely be significant movement soon in the industry as “major players try to leapfrog the competition”
Another item that’s clear from the report is the fact that secretive powerhouse Magic Leap is an impressively hulking force in the industry. Their $542M Series B led by Google in October of 2014 presents a pretty clear kink in the generally nice upward trend of yearly investments.
The report also obviously doesn’t include Magic Leap’s (still unconfirmed) 2015 raise, which Forbes reported clocked in at a staggering and industry-dwarfing $827 million.
The report has a pretty bullish outlook on the future growth of VR/AR, suggesting that the “next platform shift to AR/VR looks like it could drive growth to $120 billion by 2020.” That is a hell of a lot of dough.
