Video: Using foam to protect soldiers from bullets

A changeable material that alters depending the force that is put on it could be used as part of  helmets to protect the military in combat situations.

The technology from D3O, an impact protection company,  is currently used to produce a shock-absorbing material for a range of products from footwear to military equipment.

The company has now developed the technology into a new foam, which is to be used inside helmets for soldiers.

If the original material is moved slowly, as show in the video below, then it behaves more like a liquid. Whereas if it is moved very quickly it behaves with some of the properties of a solid.

This can lead to it being used for protection from high impacts.

Military engineer, James Fyfe, said: “The new military helmet line we are making is called the shock absorbing helmet solution. It is performing to a higher velocity impact.

“We’ve designed new foam to attenuate this level of impact which is designed to take two impacts at a very high energy to provide the soldier with a comprehensive level of protection.

“This is something that no-one else has done yet so it is a very innovative product and it is going to be the first to market with a really high performing helmet line.”


Explaining how the material works, Louise Wilson, communications and marketing manager at D30, said it can be changed to suit a range of different purposes.

Because it is a “rate-sensitive material”, the harder the impact the greater the reaction of the material.

“In standard conditions it behaves like a liquid – the molecules flow freely – but then under stress but under strain or impact it behaves like a solid and the molecules lock together to absorb and dissipate impact energy,” she said.

The technology, which is patented, has been used in electronic products and was even used by the US and Canadian ski teams during the 2006 Winter Olympics.

NASA scientists reveal their plan for finding life beyond Earth

On July 14, a panel of experts in astronomy and engineering met at the NASA headquarters to discuss the newly developing technology that could help us discover life on other planets.

Charles Bolden, administrator of NASA, opened the discussion by recounting the discoveries made by the Kepler Space Telescope. “Over the course of its life [the telescope] has shown that our galaxy is host to billions of planets and planetary systems, that small planets the size of Earth are common and that planets come in astonishing diversity.”

As our understanding of this diversity increases, so does the possibility of finding life on other planets—but how can we search for life beyond earth?

The panellists proposed that the answer lies in the James Webb Space Telescope, a highly advanced tool that is poised to shoot into space in October of 2018.

The telescope will collect data in space, looking for planets with habitable conditions such as signs of greenhouse gases.


To ensure that the telescope works properly, NASA is rehearsing and testing it at various sites throughout the US in both extremely hot and cold conditions. The team is building two of every component of the telescope, designing it with several panels that unfold to collect solar power and collect data.

One of the many difficulties in detecting habitable planets is that planets can be billions of times fainter than their parent stars, making it challenging to detect and photograph them.

However, the designers of the James Webb Telescope have developed a device called a starshade to combat this problem. The starshade’s flower shape helps block out light from the parent star for a clearer view of the planet.

The telescope also uses lightweight replicated optics to create a larger but less weighty design, compactable because of its folding elements.


While the James Webb Telescope does not guarantee any groundbreaking discoveries, it is the next step in a graduated approach to finding life in space. First, the telescope will help us learn how to characterise atmospheres of other planets and determine signs of life.

According to planetary scientist Sara Seager, the shift towards big data is playing an integral role in potential discoveries, as well. “It will be the new discoveries and the statistics, having lots of the same object, knowing how many numbers there are and what their distribution is. I think our hope is… understanding planet formation.

“Only with more and more data, covering all of the regimes of planets possible, can we start to understand planet formation in detail.”

Then, the next generation of scientists must take this understanding gained from the James Webb Telescope and develop an even more sophisticated technology that is lighter and more powerful to continue the progress.
