The Rise And Rise Of Omnipresent Digital Assistants

TechRadar recently asked ‘what happens when our assistants are smarter than us?‘. The author made a good point – that these assistants, like Alexa, OK Google, Siri, Bixby, et al are all still the first generation and are likely to improve – but mixes up the physical device (like the Echo or HomePod) with the digital assistant. At the moment, digital assistants are associated with particular devices but once Apple’s HomePod arrives and other companies integrate Alexa or OK Google into their products, consumers will start to understand that these assistants can be in their pocket and in their home and are no longer tied to a single form factor.

But, if these digital assistants are going to reach into every part of our lives then they would be much more useful if they better understood the world around them as well as the commands we use.

The author of the TechRadar piece makes the point about the assistants needing to understand more complex things beyond just location. Don’t get me wrong, location awareness is really important for lots of reasons but there are other more useful sensing capabilities.

The broad consumer technology sector talks up artificial intelligence but if we want to create products capable of responding in human-like ways then we have to teach them to understand context and the world around them in the same we do – through our senses. Products respond to our touch, computer vision technology can recognise us visually, there are companies like Owlstone developing technology that can ‘smell’ and ‘taste’, and we have products that can respond to our voices. But there is so much more information that we can extract from the things we can hear but not see.

Understanding specific and significant audio events or having a better understanding of an audio environment allows the digital assistant – whether running on a smart speaker, phone, car, headphones or wearable – to react based on what it knows and what it believes that you want or need. This means that we have to provide those local sensing capabilities within each environment and product, which in turn provides the digital assistant with information that it needs to provide its holistic, multi-device services.

For example:

  • If my personal assistant knows that I’ve been sneezing at home, in the car, at the office, and it knows that I’m about to head home, and it knows that the pollen count is forecast to be high, then it will be able to turn on the HEPA filter at home and in the car before I arrive. And it will do these things automatically.
  • If my assistant hears that my baby is crying in the night, it can turn on my hallway lights to a low hue so that I don’t trip over, play a soothing lullaby through the smart speaker to help my baby back to sleep, and maybe buzz my wearable to help me respond quicker.
  • Or perhaps my personal assistant knows that I’m cooking in the kitchen and automatically changes the sound equaliser of my smart speaker so that I can hear my music above the crashing and banging of pots without me having to ask it.

I think that as more context-sensing capabilities like hearing are embedded within devices, these cloud-based personal assistants will become more intelligent and more helpful. As a result, the mainstream consumers (who are starting to embrace smart homes and smart speakers) will see how this technology can be really helpful to us without attempting to take over the world or surpass our own intelligence.

Why We Shouldn’t Be Afraid To Embrace Technology In The Classroom

Annual global spending on educational technology in schools has been valued at £17.5bn and is set to rise to £19bn by 2019. However, worryingly, a recent report by OECD stated that students who use computers frequently at school get worse results.

This is baffling to me. While it’s claimed that the use of technology in the classroom doesn’t boost academic achievement, surely it’s wrong to value our children’s education purely by their exam results? Besides, in the teaching of STEM subjects, in particular, there is evidence to suggest that that the use of technology to support teacher-led learning can increase engagement and improve learning effectiveness.

Perhaps, it’s the way we are using technology, rather than its presence that is the problem. Here’s why we should embrace technology in the classroom and some exciting ways it’s already being harnessed to improve learning experiences.

Active learning and increased engagement

Active learning encourages students to engage with resources, participate in class and work together. We know that activities such as discussion groups and collaborative projects encourages pupils to engage with lessons and helps them to retain information.

Research backs this up and shows that active learning has a positive impact, particularly amongst students in STEM fields. One study found that active learning reduced failure rates in mathematics, science and engineering university courses by 11%.

One way to optimise the classroom for active and interactive learning is through the effective use of interactive projectors or interactive whiteboards (IWB’s). Making use of interactive technology has been found to have a positive impact on students’ motivation, engagement and self-esteem.

Using an IWB as a central hub for brainstorming and research, to answer questions or complete games as a class, can increase engagement. Pupils can put together their own mini-lessons and lead the class. The ability to embed video, link to further reading and identify discussed locations using Google Maps encourages real-life research skills, and gives our children a great grounding for higher education.

Access to immersive experiences

The advent of accessible virtual reality equipment has opened a world of possibilities for immersive learning. Students can now travel the world and visit important historical moments from the comfort of the classroom. Teachers can take them to Machu Picchu, Antarctica or even the International Space Station.

Educators have long relied on video documentaries or photographic series to bring places or events to life. While such sources are important to our children’s learning, they view these passively, sitting behind desks and watching the images rather than being able to interact with them.

Initiatives such as Google Expeditions support teachers in harnessing VR technology for educational purposes and bring learning to life. Students can experience the Apollo 11 Space mission, walk through a museum or explore the ocean floor while annotating key discoveries and discussing their experiences.

In the US, Google is taking the experience one step further by exploring the educational applications of Augmented Reality. Expeditions AR uses Google technology to map the physical classroom and place 3D objects that pupils can walk around, identify details and step back to see in a wider context.

Addressing the skills gap

While the technology sector in the UK has attracted 28bn in investment since 2011, finding high-quality candidates to fill positions in the tech sector is proving problematic. Potential STEM employees are almost twice as likely to miss job opportunities due to lack of skills.

However, initiatives such as the BBC micro:bit are tackling the demand for digital literacy head-on. The pocket-sized, programmable computer was given to every year 7 in the UK last year. It can be connected to various other devices, sensors and objects and was launched to inspire a new generation of coders. Easy-to-use software complements the device, ensuring it’s accessible to a younger audience. The micro:bit can also be used in conjunction with devices like the Raspberry Pi, opening up possibilities to more complex learning. There’s plenty of support online in the form of videos, forums and how-to articles to help support your child’s learning at home.

Also available to schools, completely free of charge, is Scratch. Developed at the MIT Media Lab, Scratch gives students the opportunity to code their own interactive stories and animations. It’s ideal for younger children as they can see the results of their programming in a way they understand. Pupils can also share their creations online, fostering collaborative working and collective creative thinking.

With so many free, practical tools available to support digital learning at a young age, there’s plenty of easy ways we can begin to lay the foundations for digital literacy.

Learning is about more than just exams

One of the biggest benefits of technology is that it gives students access to interactive, timely, high-quality learning materials at the touch of a button. Instead of relying on dusty, out-of-date textbooks and resources, technology opens up the possibility of discovering fluid, cutting-edge research. Students can follow real-time events, share their ideas online and access a range of tools to support learning. In a world of 24-hour news and continuous social media updates, our children need to be able to work in this way to keep pace with the modern world.

Above all, it’s clear that there’s far more to gain from investing in technology in the classroom than purely boosting academic results. Global institutions have identified a need to prepare the next generation for a world crying out for digital skills and are investing in developing solutions. If we fail to equip children with the expertise they need to compete in our evolving jobs market, there is a very real danger that they will fall behind.

This Terrifying App Simulates What Would Happen If A Deadly Virus Swept Through The UK

A new app is allowing scientists to conduct a nationwide citizen experiment that could save the UK from the deadly effects of a viral pandemic sweeping the nation.

The BBC-commissioned ‘Pandemic’ app is now available for anyone with a smartphone to download, and will be tracking your movements over a 24 hour period, to see where and with whom we interact.

The idea is that this information (which is totally anonymous) will then allow a team of mathematicians at The University of Cambridge and London School of Hygiene and Tropical Medicine, led by Dr Hannah Fry, to build a contagion model that shows how diseases spread.

BBC Pandemic

In 1918 Spanish flu was responsible for killing over 50 million people globally, and a century later influenza still tops the list of risks to our country on the Civilian Risk register.

According to the UK government, a pandemic of flu (not just seasonal coughs and colds) could see up to 50% of the population experience debilitating symptoms, and as many as 750,000 fatalities in a short space of time.

Unfortunately modern air travel and the extent of global movement means that stopping a pandemic is “really hard, if not impossible” so instead we have to rely on a robust plan of action.

This plan requires scientists being able to accurately predict how these diseases spread through populations, in order to devise a dynamic healthcare plan based on evidence. 

BBC Pandemic

But obviously no one wants to volunteer to contract avian flu and spread it to all their friends and family, so the app acts as a marker.

Nobody gets ill, no phone is “infected” and downloading the app is not downloading a virus, so can’t be passed from phone to phone.

It will track your approximate position (to within about a squared kilometre) once per hour for 24 hours.

At the end you’ll be asked about the number of people you had significant contact with (this means proper face-to-face conversation or physical contact, handshake, hug, kiss).

And don’t worry, it is data grouped for anonymity – so no one in charge of the experiment will know exactly where you are at any point.

The team are hoping to encourage as many people as possible to take part, and if they are able to reach a pool of 10,000 people, they will reach a new gold standard. That means the resources they are able to create are better than anything we currently have at our disposal.

There is one experiment going on a national-scale as well as a localised one in Haslemere, Surrey.

To download the app, search ‘Pandemic’ in the App Store or Google Play.

There’s A Sustainable Energy Source You’ve Never Heard Of And It Could Power Most Of The USA

By now we’re all familiar with the likes of solar and wind power as alternatives to using up unsustainable fossil fuels, but what about evaporation?

That’s right. A team of scientists have successfully exploited nature’s basic cycle of moving water between land and air in order to create energy, and it’s already looking more promising than other green options we have.  

And this is no small contribution – researchers at Columbia University found that lakes and reservoirs across the USA could generate 325 gigawatts, nearly 70% of what the country currently produces.

Research has previously shown that evaporation can produce energy, but the most recent study is the first that set out to discover just how much energy this method could potentially produce if replicated on a larger scale than just in the lab.

The system works by using a humidity-controlling machine that opens and closes a shutter forcing bacterial spores to expand and contract and transfer energy to a connected generator.

This is beneficial because it doesn’t require back-up batteries like solar and wind power (which are expensive and toxic to make), “evaporation comes with a natural battery,” explained lead author Ahmet-Hamdi Cavusoglu.

“You can make it your main source of power and draw on solar and wind when they’re available.”

Published in Nature Communications, the team found that evaporation was a worthy competitor in terms of energy generation, and not only that but it could used on demand, day or night and without certain weather conditions, thus overcoming the intermittency problems plaguing solar and wind energy.

The study also showed that evaporation technology can save up to 25 trillion gallons of water from going to waste (by evaporating into the atmosphere) a year, or about a fifth of the water Americans consume.

Water strapped states, such as California, Arizona and Nevada, with growing populations could benefit most from this.

Klaus Lackner, at Arizona State University who was not involved in the study, but is working on a similar project that sees artificial trees draw carbon dioxide from the air, in part, by harnessing the power of evaporation, expressed support for the team’s findings.

“Evaporation has the potential to do a lot of work,” he said. “It’s nice to see that drying and wetting cycles can also be used to collect mechanical energy.”

They are now hoping to test the concept on a lake, reservoir or even greenhouse.

Health24.com | 10 random daily things that are making your hair fall out

Every day, you lose about 50 to 100 hairs from your scalp. Don’t worry, new hairs grow back in.

It’s all part of your hair’s programmed life cycle, which consists of three phases: the growth phase, the shedding phase and the resting phase.

But when excessive hair loss or thinning of the scalp begins to happen, it’s because this cycle has been disrupted, or because the hair follicle has been destroyed and replaced by scar tissue. As a result, gradual thinning, receding hairlines, bald patches and complete baldness can occur.

Hair loss is attributed to many different causes, ranging from common to the not-so-common. It affects more men than women, but the latter’s still susceptible to it.

Here are 10 causes that can trigger adverse hair loss in women.

1. Extreme stress

According to dermatologist Marc Glashofer, experiencing a highly stressful event such as a physical injury or severe anxiety can cause shock to the hair cycle, pushing more hair into the shedding phase. Also, fewer hair follicles are available to grow new hair during the growing phase. This can trigger telogen effluvium, a type of hair loss that sees as many as 70% of the scalp hairs being shed, usually in handfuls. It becomes noticeable about two to six months after the shock occurs.

Fortunately, the body begins to go back to normal once the stress is over, which will then kickstart your hair’s growth cycle. It’s important to nurture your physical and mental health so that your hair cycle can continue unhampered. Partaking in regular exercise programmes or learning relaxation techniques like meditation are amongst some of the steps you can take towards maintaining your mane.

2. Hereditary

If hair loss runs in the family, chances are that you may be prone to it, too.

Androgenetic alopecia, or female-pattern hair loss (FPHL), causes thinning on all areas of the scalp including the widening of your parting. This leads to increased diffuse hair shedding or a reduction in hair volume, or both. It’s the most common form of hair loss, affecting 40% of women by age 50.

The American Academy of Dermatology says that FPHL is hereditary, meaning you inherit the genes from either parent or both. However, there are multiple genes that contribute to FPHL, genes which have yet to be established as causative. Factors tied to hormones also play a major role, so FPHL can also occur after menopause or pregnancy.

Minoxidil is the preferred medication to use to treat FPHL, as you can easily apply it to your dry scalp.

3. Lack of nutrients

Sometimes hair loss comes down to what you eat – or rather, what you don’t eat.

Like the cells in our bodies, hair thrives on a diet rich in vitamins, minerals and antioxidants. Without these necessary nutrients, your hair will feel the damaging effects.

A lack of Vitamin C – which aids in the synthesis of collagen, a structural fibre that hair follicles needed for growth – can make your hair dry and brittle. Protein powers growth in hair cells, but an absence of it results in less new hair growth. Iron helps red-blood cells to carry oxygen; once your iron levels are low, you become anaemic and your cells struggle to function, causing you to lose your hair.

Zinc is important for tissue growth and repair, plus it keeps oil glands around the hair follicles in good working order. But if your zinc intake is low, you’ll experience slow hair growth and dandruff in addition to the hair loss.

To prevent your hair from “starving out”, start eating foods that contain these vital nutrients. Oranges, mangoes, cauliflower and tomatoes contain Vitamin C, whilst protein can be found in meats, eggs, fish, yogurt and beans. Whole-grain cereals and dark green leafy vegetables are great for providing you with iron, plus you will need zinc-rich foods like nuts, chickpeas and sweet potatoes.

4. Weight loss and crash diets

A sudden or excessive loss of weight can result in the thinning and loss of hair. Like stress-induced hair loss, drastic weight loss can be a shock to the system, which can trigger telogen effluvium.

Stress from dieting can cause more hairs than usual to fall out during the shedding phase. Vitamin or mineral deficiencies are also major factors. Usually you will see hair loss three to six months after you’ve lost weight, and then the hair cycle will start to correct itself.

To prevent hair loss when losing weight, make sure to incorporate meats, eggs, whole grains, fruits and vegetables into your diet. They’re rich in protein, iron, Vitamins A and C, and zinc, all of which are essential components for hair growth.

5. Ageing

Once you reach 40, you may find that your hair isn’t as bouncy and full as it used to be. As we age, our bodies begin to lose the ability to renew and regenerate cells quickly. This results in thinning hair, hair loss and greying.

Research also points to menopause as a cause of hair loss as the body undergoes hormonal changes during this process. A decrease in hormones like oestrogen and progesterone, which help to grow and retain hair, leads to slow hair growth and thinning. This prompts the increased production of androgens, a group of male hormones. Androgens shrink hair follicles, resulting in hair loss on the head.

Eating a balanced diet of lean proteins, vitamins and minerals is one way to deal with thinning hair. If your hair’s on the dry side, consider using moisturising products that contain Argan oil or hazelnut oil to nourish it.

6. Childbirth

During the pregnancy itself, your oestrogen levels will have increased, meaning your hairs remain in the growing phase. So don’t be surprised if your hair looks and feels fuller.

However, hair loss occurs approximately three months after the delivery. That’s because your hormones are returning to their normal levels, causing the hair cycle to resume. Don’t panic if your hair suddenly starts falling out all at once – your hair will recover within six to 12 months as your follicles start to rejuvenate themselves.

To reduce hair loss after your pregnancy, supplement your diet with fruits and vegetables rich in Vitamins B, C and E, and zinc to promote hair growth.

7. Overstyling

Over time, your hair can start falling out due to the stress caused by vigorous over-styling and hair treatments.

Traction alopecia, or gradual hair loss, is caused by hairstyles that pull your hair tight. Braids, cornrows, pig-tails and weaves, as well as hot-oil treatments and chemical relaxers, puts the hair under constant strain, which can affect the hair follicles to the point that these hairs may never grow back.

Think about wearing your hair down, changing your hairstyle every couple of weeks (alternating between loose hair and braids, for example) or avoid chemically processing your hair if you use weaves or braids.

Scalp massages are great for effective hair regrowth: olive oil, castor oil and unrefined coconut oil make for fabulous massage agents.

8. Medications

Certain medications could be the reason why you are experiencing hair loss. They are toxic to the hair follicles, and the damage leads to a disruption in the hair cycle.

Anti-coagulants (blood thinners that help to combat blood clots) are the most common hair loss-inducing medications and can trigger telogen effluvium. Blood pressure drugs like beta-blockers, gout medications like Allopurinol and exceptionally large doses of Vitamin A can also cause your hair to fall out. Luckily, this type of hair loss is temporary.

Speak to your doctor to find out which of your medications could be causing your hair loss. Also speak to your doctor about perhaps being prescribed a different medication, lowering your current dosage or recommending a viable treatment that will aid in minimising your hair loss.

9. High-energy sport

“During high-intensity exercise or sport, muscles consume a huge amount of energy, draining the rest of the body of energy, including the hair,” says Dr Adolf Klenk, a hair expert. “This causes hair to suffer and may result in hair loss.”

Other factors include using steroids to boost your physical performance and a lack of proper hair care, such as letting sweat build up in your hair for days on end. Eating nutrient-rich foods will provide your body with the components it needs to promote hair growth.

Additionally, caffeine-based shampoos that contain taurine and special micronutrients including biotin, zinc, magnesium and calcium can also help stimulate the hair to grow.

10. Trichotillomania (hair-pulling)

Trichotillomania is a mental disorder that causes people to compulsively pull out their hair from their scalp, eyebrows or other areas of their bodies. It occurs more frequently in women, and it’s estimated that 1-2% of adults and adolescents suffer from it.

The repeated pulling of your hair can damage your hair follicles, resulting in bald patches and near permanent hair loss. It can also be highly distressing, as it can interfere with your social and work functioning.

Although treatment of trichotillomania is limited, there are types of therapy available. Habit-reversal training enables you to recognise when you’re likely to pull your hair and how to substitute other behaviours instead, such as clenching your fists to help stop the urge to touch your hair. Your doctor may also recommend using an antidepressant like Clomipramine to help control the symptoms.
