Despite indications of recovery, the global economy remains in a fragile and turbulent state. While growth is strongest in developing countries, it is still slower than during the pre-crisis period. A cautious attitude and ongoing aversion to risk mean that business confidence is tepid – especially in the EU, which has borne the brunt of this disruption.* There is much political and social unrest in the southern European countries of Portugal, Italy, Greece and Spain, where debt continues to spiral.*
After reaching a plateau in 2008, global trade is showing improvement now, but is still trending at or below the average for the previous few decades. Unemployment remains high in Europe (12%), which consumes one-third of the world's traded goods* and where austerity measures have persisted.* Although it has undertaken reforms like the Single Supervisory Mechanism,* Europe's banking system has yet to be fully repaired.
The US is seeing faster growth than Europe, but remains in a fiscal deadlock over its debt ceiling, with periodic brinkmanship between Democrats and Republicans,* now more polarised than ever before.* Although the annual budget deficit has fallen significantly,* it will soon begin rising again* – due to pressures of an aging population, rising healthcare costs, expansion of federal subsidies for health insurance, and growing interest payments on national debt, the latter still alarmingly high at over 70% of GDP and set to reach 100% by the 2030s.*
China's annual growth rate, while high compared to most countries, has been slowing in recent years* – due to a combination of local government debt, serious environmental issues, overcapacity and structural imbalances.* Major demographic challenges are now emerging from its aging population and declining workforce. The resulting labour shortages have driven up wages, reducing the competitiveness of its exports.* This demographic trend is even more of a problem for neighbouring Japan.*
Emerging OECD members that are faring much better include Chile, Israel, Mexico, South Korea and Turkey.* Overall, the global economy is recovering, but at a frustratingly slow pace compared with previous such crises. Some of the most rapidly growing industries now include agriculture,* alternative energy,* biotechnology,* computer systems design, e-commerce, healthcare, mining* and scientific/technical consulting.*
Personal genome sequencing explodes into the mainstream
The use of bioinformatics in healthcare is growing exponentially during this time, thanks in large part to the falling cost of genome sequencing. This is creating a new generation of personalised diagnosis and treatments that can be specifically tailored to an individual's own DNA.*
After the Human Genome Project was finished in 2003, its potential for public use began to be realised. It had taken nearly 15 years and billions of dollars to identify and map all 3.3 billion base pairs in the human genome. However, the methods used to achieve this goal were improving at a rate even faster than Moore's Law in computer chips.* From 2008, the cost per genome went into freefall.
Among the early adopters was 23andMe, a company which offered partial genome sequencing to customers. Despite a slowdown of cost reductions in the early 2010s,* along with regulatory hurdles,* this company along with a range of others entering the market had already opened the floodgates. In the second half of the 2010s, average costs for whole genome sequencing would continue to fall* – reaching less than $1000** – while even greater advances were made in the portability* of machines for analysing samples. Thanks to nanopores and other novel technology,* these were now becoming so compact and fast that it was possible to get results from a handheld device in a matter of minutes, at low cost.
By the end of this decade, these genome sequencers have a wide range of practical applications. They can be used at crime scenes, for example, to analyse biological evidence without having to return to the laboratory, saving time and money. Foreign aid workers in developing nations can identify viruses and verify water quality. Food inspectors can check for harmful pathogens in restaurants. Wildlife biologists can study genes in the field.
But perhaps the most widespread use of genome sequencing is now among the general public, who can utilise it for a mere fraction of the cost in the previous decade. Just as the Internet seemed to appear out of nowhere during the mid-1990s, personalised genomics is now exploding into the mainstream. Its popularity stems from the health benefits and medical insights it offers: after the base pairs are sequenced, an individual's genotype can be cross-referenced with a database of published literature to determine the likelihood of trait expression and disease risk later in life. This allows them to prepare years or even decades in advance and to seek treatment or advice at a much earlier stage.* By 2020, tens of millions of human genomes have been sequenced in countries around the world. At the same time, however, concerns are being raised over privacy of information and the potential for "genetic discrimination", as well as the psychological impact of test results.
Five-year survival rates for thyroid cancer are approaching 100%
The thyroid is one of the largest endocrine glands. Found in the neck, it controls how quickly the body uses energy, makes proteins and controls how sensitive the body is to other hormones. It does so by producing thyroid hormones which regulate metabolism and affect the growth and rate of function of many other systems in the body.
Worldwide, an estimated 213,000 people were diagnosed with thyroid cancer in 2008. More than a quarter of cases occurred in the US. However, treatments already existed that offered an excellent prognosis. In addition to surgery (which included thyroidectomy, lobectomy and tracheostomy), numerous drugs were being developed that improved the outlook for sufferers still further. In the second half of the 2010s, five-year survival rates are approaching 100% in much of the developed world.**
reality makes a comeback
improvements in processing power (doubling every 18 months) are enabling the creation of highly lifelike
graphics and 3D environments. At the same time, faster broadband is
opening up new frontiers in cyberspace, allowing the development of
Web 3.0 – the next generation of Internet. This is being combined with developments
in on-person hardware, creating renewed interest in virtual reality.* Having been something of a gimmick in the 1980s, it is now becoming a serious tool for business, leisure, education and training.
the content in these 3D environments is user-generated, with online communities
for sharing and exchanging virtual objects, buildings, avatars, etc. Among the popular hardware configurations to emerge is a circular treadmill-like interface, allowing players to move freely and naturally in all directions.*
The deadline for the Millennium Development Goals
In 2000, the largest gathering of world leaders in history took place, as the 193 UN member states met in New York to discuss the Millennium Development Goals (MDGs). These were eight international objectives with ambitious targets for developing countries, most of them to be achieved by 2015.*
• Goal 1: Eradicate extreme poverty and hunger
– By 2015, reduce by half the proportion of people living on less than $1 a day.
– By 2015, reduce by half the proportion of people who suffer from hunger.
• Goal 2: Achieve universal primary education
– By 2015, ensure a full course of primary schooling for boys and girls alike.
• Goal 3: Promote gender equality and empower women
– By 2005, eliminate gender disparity in primary and secondary education; and at all levels of education by 2015.
• Goal 4: Reduce child mortality rates
– By 2015, reduce by two-thirds the number of children dying under age five.
• Goal 5: Improve maternal health
– By 2015, reduce by three quarters the number of women dying from complications of pregnancy and childbirth.
• Goal 6: Combat HIV/AIDS, malaria, and other diseases
– By 2015, halt and begin to reverse the spread of HIV/AIDS.
– By 2015, halt and begin to reverse the incidence of malaria and other major diseases.
• Goal 7: Ensure environmental sustainability
– Reverse the loss of environmental resources.
– By 2015, halve the proportion of people lacking access to safe drinking water.
– By 2020, achieve significant improvement in the lives of at least 100 million slum dwellers.
• Goal 8: Develop a global partnership for development
– Address the special needs of the least developed countries, landlocked nations and small island developing states.
– Deal comprehensively with the debt problems of developing countries through national and international measures, in order to make debt sustainable in the long term.
– In cooperation with the private sector, make available the benefits of new technologies, especially information and communications technologies.
To accelerate progress towards the MDGs, the G-8 Finance Ministers met in London in June 2005 and reached an agreement to provide enough funds to the World Bank, the IMF and the African Development Bank to write off $55bn of debt owed by the Heavily Indebted Poor Countries (HIPC). This would allow these impoverished nations to re-channel the money saved from the cancelled debt to social programs for improving health and education and for alleviating poverty.
Achieving the MDGs would not necessarily depend on economic growth alone and expensive solutions. In the case of MDG 4, some developing countries like Bangladesh showed that it was possible to reduce child mortality with only modest growth, via inexpensive but effective interventions such as measles immunisation. A number of important and innovative new technologies were also emerging – such as the $100 laptop project,* the LifeSaver bottle* and the genetic engineering of mosquitoes.*
By 2010, some countries had achieved many goals, while others were not on track to realise any. The countries with major success stories included China (whose citizens in poverty fell from 452m to 278m), India, Brazil, Thailand, Vietnam, Cuba, Honduras, Nicaragua, Ecuador and Ethiopia.
However, some regions in Sub-Saharan Africa failed to make any significant changes in improving their quality of life. The prevalence of hunger in the Democratic Republic of Congo (DRC), for example – Africa's 2nd largest country – more than doubled, while Zimbabwe saw a nearly 50% increase in poverty and Kenya's child mortality rate increased from 105 to 128 per 1000.
Progress towards reaching the goals was therefore mixed. There were setbacks and disappointments. But overall, the reduction in poverty and increased access to health, education, technology and other essential services was without precedent in many countries' histories. Of particular note was the number of deaths due to AIDS, which saw a dramatic levelling off and decline.*
By 2015, increasing global uncertainties such as the economic crisis, peak oil and climate change have led to a rethink of the MDG approach to development policy, with a new set of goals for 2030.
The Eurasian Union is formed
The Eurasian Union is a political and economic union of Belarus, Kazakhstan, Kyrgyzstan, the Russian Federation, Tajikistan and other countries, in particular the post-Soviet states. The idea, based on the European Union's integration, was brought to attention in October 2011 by then-Prime Minister of Russia, Vladimir Putin, but was first proposed as a concept by the President of Kazakhstan, Nursultan Nazarbayev, during a 1994 speech at a Moscow university. On 18th November 2011, the presidents of Belarus, Kazakhstan and Russia signed an agreement, setting a target of establishing the Eurasian Union by 2015. The agreement included a roadmap for the future integration and established the Eurasian Commission (modelled on the European Commission) and the Eurasian Economic Space, which started work on 1st January 2012.
It was speculated that future expansion of the Union might allow membership for other countries that have been historically or culturally close – such as Finland, Hungary, the Czech Republic, Bulgaria, China and Mongolia, incorporating them into a common state body where Russian would be the common language of communication and economic cooperation. According to Vladimir Putin, the Eurasian Union would build upon the "best values of the Soviet Union". However, critics expressed some concern at this "re-Sovietization" of Russia and Central Asia. The United States opposed the integration effort on human rights grounds.*

Expo 2015 is held in Milan, Italy
The Universal Exposition is held in Milan this year, the first time the city has hosted the event since 1906. The main theme of the exposition is the future availability of food and water supplies and the state of nutrition and health in the years to come. New technology is on display, all with the aim of reducing poverty and famine around the world, as well as the spread of infectious diseases. A working prototype of a vertical farm is also presented as an alternative to traditional agriculture.
This event serves as a catalyst for talks between concerned parties such as farmers, non-profit organisations, humanitarian workers and environmentalists, initiating new movements for change. Over 100 nations from around the world participate in the Expo. By the time it finishes in late 2015, many millions of people have visited.*
Large Hadron Collider reaches its maximum operating power
Large Hadron Collider (LHC) is the world's largest and highest-energy
particle accelerator. By smashing together sub-atomic particles at close
to the speed of light, it aims to recreate the conditions that existed
just a fraction of a second after the birth of the universe. In doing
so, it is expected to address some of the most fundamental questions
lies in a tunnel 27 kilometres (17 mi) in circumference, as much as
175 metres (574 ft) beneath the Franco-Swiss border near Geneva, Switzerland.
This synchrotron is designed to collide opposing particle beams of either
protons at an energy of 7 tera-electronvolts (7 TeV) per particle, or
lead nuclei at 574 TeV per nucleus. The term "hadron" refers
to particles composed of quarks.
was built by the European Organisation for Nuclear Research (CERN) with
the intention of testing various predictions of high-energy physics,
including the existence of the hypothesised Higgs boson, and of the
large family of new particles predicted by supersymmetry. It was built
in collaboration with over 10,000 scientists and engineers from over
100 countries, as well as hundreds of universities and laboratories.
2008, the proton beams were successfully circulated in the main ring
of the LHC for the first time – but nine days later its operations were
halted due to a serious malfunction. In November 2009, they were successfully
circulated again, the first recorded proton-proton collisions occurring
three days later at the injection energy of 0.45 TeV per beam. After the
2009 winter shutdown, the LHC was restarted and the beam was ramped
up to half power, 3.5 TeV per beam (i.e. half its designed energy).
In March 2010, the first planned collisions took place between two 3.5
TeV beams – a new world record for the highest-energy particle
collisions. The LHC
continues to operate at half power until 2015, when it reaches maximum
design capacity of 7 TeV.*
Initially, the experiment
sparked fear among the public that the collisions might produce a doomsday
scenario, involving microscopic black holes or hypothetical
particles known as strangelets. Two CERN-commissioned safety reviews
examined these concerns and concluded that the experiments at the LHC
presented no danger and that there was no reason for concern, a conclusion
endorsed by the American Physical Society.
Windows 9 is released by Microsoft
Following the much-criticised Windows 8, Microsoft launches a major overhaul of the operating system in 2015. Windows 9.0 addresses a number of usability issues – refining the "Metro" design language of its predecessor and providing a more distinct experience for desktop, mobile and other platforms. This includes a return of the traditional Start Menu. The OS introduces a more unified code base, for improved compatibility and simpler transfer of data between various devices and services. There is a much greater focus on apps. Highly advanced gesture recognition is also incorporated, now that 3D cameras are becoming more common. It also deals with power management issues. Initially codenamed "Threshold", it is released in April 2015.**
The world's first fully sustainable, zero-carbon, zero-waste city
The first phase of Masdar City – a $22 billion eco-project – is completed in 2015.* This huge development is located outside of Abu Dhabi in the United Arab Emirates. Entirely pre-planned and self-contained, it is the world's first carbon neutral, zero waste and fully sustainable city. A multitude of green technologies are utilised – including the largest solar power plant in the Middle East, rooftop photovoltaics, wind farms, geothermal sources and a hydrogen power plant. The city's water needs are fulfilled by a solar-powered desalination plant. There are extensive recycling systems too.
Masdar City will initially be home to around 7,000 residents and 15,000 commuters. Its commercial sector is primarily concerned with the manufacture of environmentally-friendly products. Automobiles are banned from the city, residents instead using integrated forms of mass transit and personal rapid transit.* It is connected to the rest of Abu Dhabi through rail and existing roadways. It contains a university, an institute of science and technology and hosts the headquarters of the International Renewable Energy Agency (IRENA).
Masdar City will undergo major expansion. The final phase of the project will be completed by 2025, covering an area of 6 sq km (2.3 sq mi). By then, it will contain over 50,000 residents and 1,500 businesses.*
The first self-regulating artificial heart
In 2013, French Professor Alain Carpentier engineered the first self-regulating artificial heart, using biomaterials and electronic sensors. The device weighed 900g, was roughly the same size as a real heart and could imitate its functions exactly. In a 10-hour operation, it was successfully implanted within a 75-year-old patient at the Georges Pompidou European Hospital in Paris.*
Permanent artificial hearts had been around since 1982, with similar inventions that preceded them going back to the 1940s. Unlike previous versions, however, Carpentier's invention was the first to be completely artificial and self-regulating. Electronic sensors and microprocessors could monitor blood pressure and flow in real time – instantly adjusting the pulse rate – while a "pseudo-skin" made of biosynthetic, microporous materials could prevent blood clots, which had been a major issue in the past.
By 2015, after a period of clinical trials, it is available within the European Union, priced between 140,000 and 180,000 euros (about US$190,000 to $250,000).*
new generation of hi-tech supercarriers
first in a new generation of US aircraft carriers is launched this year.
The Gerald R. Ford-class replaces the aging Nimitz-class
which has been in service since 1975. This new class of ship includes
some major improvements over previous generations. These include: increased
automation, electromagnetic aircraft launch systems to replace previous
steam mechanisms, increased stealth, a new type of nuclear reactor for
more efficient power consumption, high tech radar and flight control,
as well as the ability to carry the new F-35 Lightning II fighter jet.
Ten carriers are commissioned in total, at a cost of $14bn each (including
research and development). The 10th and final ship is launched by 2040.*
United States and South Korea dissolve the Combined Forces Command
Combined Forces Command has been in place since the end of the Korean
War. It acts as a command structure for the multinational military forces
supporting South Korea. For more than 50 years, military operations
along the demilitarised zone between North and South Korea have been
under the command of the USA. This structure is dissolved in 2015,
with operations being handed over to South Korea.* From this
point onwards, South Korean and American
forces will operate as two separate entities during wartime. This event comes at a
time of great stress between North and South Korea. North Korea has
continued to conduct missile tests, to the continued disapproval of
The first large-scale solar updraft towers are operational
The first large-scale solar updraft towers are completed in 2015.* Built by EnviroMission – a start-up company that purchased land in Arizona, USA – they stand 800 metres in height, over twice as tall as the Empire State Building. Each generates 200 megawatts of clean, renewable energy – enough to serve 150,000 homes – and equivalent to removing 220,000 polluting cars from the roads.*
The towers work by combining three old and proven technologies: the chimney effect,
the greenhouse effect, and the wind turbine. Air is heated by
the Sun and contained in a very large greenhouse-like structure around
the base; the resulting convection causes air
to rise up the chimney. This airflow then drives turbines, producing
The towers have a number of advantages:
Because they work on temperature differential, not absolute temperature, they work in any weather;
Because the heat of the day warms the ground up so much, they continue working at night;
Since large areas of hot, dry land provide the best results, they can be built on useless and uninhabited land in the middle of the desert;
They use no resources such as coal or uranium – just air and sunlight;
They emit zero pollution. The only "emission" is warm air from the top of the tower. In fact, because of the greenhouse underneath, they can also be used for growing vegetation;
They require virtually no maintenance and will last for almost a century;
They can serve as tourist attractions, with money being generated from people wishing to experience their viewing galleries at the top.
This new technology offers hope for the future, coming at a time when the world faces an impending energy crisis. Once proven to be commercially successful, it will be deployed on a wider scale in the 2020s.
Queen Elizabeth II is the longest reigning monarch in British history
On 10th September 2015, Elizabeth II becomes the longest reigning monarch in British history – surpassing the record held by Victoria, her great-great grandmother. Having ascended to the throne on 6th February 1952, Elizabeth II has now reigned for 63 years and 217 days.*
The six decades of her reign have witnessed enormous changes on the world stage – including the dismantling of the British Empire, the civil rights movement, the growing empowerment of women in society, the development of the Space Age, accelerating globalisation, the fall of communism in Europe, the end of the Cold War, the dawn of the information age, and the rise of China, to name but a few.
Now aged 89, she is becoming noticeably frailer and has begun to scale back her official duties. The next milestone (assuming she lives that long) will be in 2022 – her Platinum Jubilee. Her eldest son Charles will succeed her, becoming King Charles III.
DDR4 memory reaches the home PC market
DDR4 is the fourth generation of double data rate, synchronous dynamic random-access memory (SDRAM) after DDR (2002), DDR2 (2004) and DDR3 (2007).* It features greater speed, memory density and energy efficiency, with devices using 20 nanometre (nm) process technology allowing consumer-grade modules of up to 32 GB.* Though Samsung and others introduced DDR4 memory boards in 2013, processor boards like Intel's Broadwell did not yet support this standard. High-end servers in data centres were able to take advantage of DDR4 in 2014. However, the home PC market would have to wait until 2015.*
Year of release
Battery technology gets a boost
Various new methods of charging lithium-ion batteries have emerged, enabling them to be powered an order of magnitude faster and lasting over ten times as long. One such technology involves a chemical oxidation process that creates miniscule holes (10 to 20 nanometres) between layers of graphene. This provides lithium ions with a shortcut to the anode. Energy density is boosted by inserting clusters of silicon between each graphene slice, which allows more ions to gather at the electrode. By 2015, the process is used in many consumer electronics. Mobile phones can now be charged from empty in under 15 minutes, with a single charge lasting up to a week. This technology also paves the way for smaller and more efficient batteries for electric cars.*
printing is a mainstream consumer product
recently, this technology was extremely expensive – upwards of $15,000
per machine – and limited to use in industrial prototyping, product
design, medical modeling and architectural models.* However, plummeting costs are now making it affordable to consumers.**

In addition to falling
costs, another reason that home 3D printing has taken off rapidly is
that there is very little manufacturing being done in America and various
other countries anymore. As a result, there is little or no pressure

LED lamps dominate the commercial and domestic lighting markets
For many years, light-emitting diodes (LEDs) were used as indicators such as red standby dots on TVs. At first, they were available only as a red light source, and their output was too low for general illumination. As the technology developed, other colours became available and the lamps became brighter, so LEDs found other roles in a wide range of appliances and equipment.
In the early 2010s, it was found that LED technology could vastly improve the brightness, colour and distribution of lighting in social housing communal areas. Not only that, but it could deliver huge energy savings (up to 90%), and reduce long-term costs and maintenance, while making residents feel safer.
Credit: The Energy Saving Trust
One study measured the performance of 4,250 LED light fittings, installed at 35 sites. The authors of the report calculated a saving of over 3.4 million kilowatt hours (kWh) each year when compared with the previous systems – equivalent to lighting 5,800 average homes for a year with traditional lighting. Residents commented that their buildings felt safer, more secure and more pleasant because they were better illuminated. The light was fresher, brighter and more like daylight.
With soaring energy prices, the high efficiency of LED lamps soon made them a very attractive investment. By 2015, this technology dominates both the commercial and domestic lighting markets.*
nanometre chips enter mass production
next generation of microprocessor technology is released by Intel, with
transistors using a 10 nanometre manufacturing process.* Over 10 billion transistors can now be packed onto a single chip. Moore's
Law will soon be hitting a wall, as the effects of quantum tunnelling
start to degrade chip performance. Traditional integrated circuits will
reach their limit in the early 2020s, with a new paradigm emerging in the form of "stacked" 3D circuits made from carbon
nanotubes, graphene and other new materials.
The Archival Disc format is launched
This year sees the release of a new optical disc format with 300GB capacity, which has been jointly developed by Sony and Panasonic. For comparison, dual-layer Blu-rays can store up to 50GB. Known as Archival Disc,* it is initially aimed at industries like digital cinema (for storage of 4K/2160p video), broadcasters and cloud centres handling big data. The discs can withstand changes in temperature and humidity, in addition to dust and water, ensuring readability for at least 50 years. Future versions with capacities of 500GB and 1TB are planned.
Even denser storage mediums will eventually become possible using molecular, holographic systems to read and write data in three dimensions. A technology known as Holographic Versatile Disc (HVD) had been demonstrated in the previous decade, with standards published in 2007. A number of release dates were announced, but these all passed.* This format will later resurface, however,* as storage requirements continue to grow exponentially.
resurrect the woolly mammoth
cloning technology has enabled the woolly mammoth – extinct for 5,000
years – to be brought back to life. Tissue samples are taken from a
mammoth frozen in permafrost. The nuclei of a viable cell is then inserted
into the egg cell of a female African elephant, which can act as a surrogate
mother. Following a 600-day gestation period, the baby woolly mammoth
attempts to clone mammoths had failed, because the cell nuclei were
too badly damaged by ice crystals; but new techniques have overcome

in a number of zoos and private collections. Other extinct mammals are
cloned too, such as the sabre-tooth tiger and Megatherium.

Dawn arrives at Ceres
Dawn is a robotic spacecraft sent by NASA on a mission to the asteroid belt.
It reaches Vesta in 2011, before rendezvousing with the dwarf planet,
Ceres, in 2015.
Vesta are the two most massive members of the asteroid belt: 950 and
530 km in diameter, respectively. Dawn is the first probe to
study and photograph them at close range. Both bodies formed very early
in the history of the Solar System, thereby retaining a record of events
and processes from the time of the formation of the terrestrial planets.
Dawn is also innovative – it becomes the first spacecraft to enter into orbit
around a celestial body, study it, then re-embark under powered flight
to a second target. All previous multi-target missions (such as the
Voyager program) have involved rapid planetary flybys.*
Trucks with emergency braking systems are mandatory in Europe
In November 2015, an EU law comes into effect which mandates that all new trucks must be fitted with emergency braking and collision warning systems.* This has been introduced in an effort to lower the number of rear-end collisions, which account for a significant proportion of road accidents.
A radar and camera, working together to identify and monitor vehicles in front, can prevent a collision with a moving target at relative speeds of up to 44 mph (70 km/h). When the system detects a vehicle that the truck will hit at its current speed, the warning system activates a constant red light in the windscreen in order to attract the driver's attention.
If the truck fails to detect any reaction from the driver, such as steering or braking, the light begins to flash red accompanied by a beeping sound. If there is still no reaction, the system applies the brakes gently. When all this fails too, an emergency braking system is activated, bringing the truck to a complete stop. In addition, to alert other drivers to the situation, the brake lights on the rear of the truck will change from fixed to flashing.
By the end of this decade, the system is being extended to cars, too.* As more and more technology appears both in vehicles and road infrastructure, the number of accident fatalities continues to trend downwards,* reaching almost zero in the latter half of the century, with human drivers being entirely replaced by AI.
