Horizon Challenge Overview (03:51)


In 2014, scientific development areas addressing 21st century issues were nominated for the new Longitudinal Prize. Professor Alice Roberts explains how the original prize was launched in the 18th century to improve ship navigation.

Antibiotic Resistance (03:29)

Experts will select one of six scientific issues for the Longitudinal Prize. Learn about the public health threat posed by bacterial super bugs. Genetic mutations allow resistant strains to grow—exacerbated by excessive antibiotic use.

Addressing Antibiotic Overuse (03:27)

Fifty million antibiotic courses are prescribed in the U.K. annually, many unnecessarily. A new blood test that measures procalcitonin levels (to distinguish a viral from a bacterial infection) is expensive and slow.

Paralysis Exoskeleton Technology (04:29)

Patients suffering spinal injuries have few mobility options beyond wheelchairs. A paralyzed woman tests a bionic device designed to allow her to stand and walk.

Mind Control Technology (03:06)

A U.K. researcher uses only his brainwaves to control a robot. Mind controlled exoskeletons for paralyzed patients will likely take decades to develop.

Addressing Malnutrition (04:18)

Over 800 million people are undernourished globally. Hear health problems resulting from vitamin and protein deficiencies. A Dutch chef prepares meal worm quiche; insects are high in minerals and more efficient to farm than livestock.

Genetically Modified Crops (02:55)

Genetic modification technology can make food more nutritious. A U.K. agricultural research center attempts to grow fish oil in camelina plants to address omega-3 deficiencies and declining fish stocks.

Marine Chronometer Innovation (05:16)

18th century clock maker John Harrison challenged conventional watch making by developing an oscillator that kept accurate time at sea and improved ship navigation.

Addressing Climate Change (02:00)

Transport is responsible for 13% of emissions. Electric cars show promise for lowering atmospheric CO2, but aviation poses a bigger challenge.

Carbon Free Flight (02:53)

A Slovenian company has produced an electric airplane. At 2500 meters, it converts into a glider for efficiency. However, the battery life is insufficient for commercial aircraft.

Hydrogen Fueled Aircraft (02:20)

Engineers are developing a spacecraft engine running on liquid hydrogen that emits water vapor. However, liquid hydrogen is expensive and requires fossil fuels for production.

Addressing Water Scarcity (02:39)

By 2025, nearly half the global population will live in water stressed areas. A portable desalination device uses sunlight to separate freshwater from salt in an inefficient process.

Desalination Technology (03:51)

A London plant uses a high pressure reverse osmosis process to separate salt from water—an expensive operation. A Gibraltar plant works with osmosis by pumping saline solution through tubing to draw salt from water.

Addressing Dementia (02:33)

With an aging population, caring for people with Alzheimer's Disease will be a major challenge. One patient lives at home and is cared for by her sister; encouraging everyday tasks can help slow the mental decline.

Dementia Care Technology (03:11)

Engineers are developing a domestic robot to help dementia patients function at home. Sensors installed in kitchen items communicate with a computer, guiding patients through simple tasks and monitoring their activities. However, these systems can't yet replace human care.

Longitudinal Prize Selection (00:54)

The choice among carbon free flight, paralysis, food, dementia care, and fresh water challenges was made; antibiotic resistance was chosen for the £10 million fund.

In this documentary, Horizon launches the 2014 Longitude Prize for a innovation that will respond to a 21st century scienfic challenge. The original Longitude Prize was awarded 300 years ago to John Harrison for his chronometer clock, which enabled ships to determine their exact position at sea. This invention reduced the number of shipwrecks and enabled Britain's global trade to flourish. Professor Alice Roberts looks at the history of this quest for a scientific solution to a life-threatening problem, while other presenters including Liz Bonnin and Michael Mosley explore six issues that could be the focus of the 2014 prize, including malnutrition, antibiotic resistance, paralysis, dementia, freshwater, and zero-carbon flight. A BBC Production.
