Glimpse at future of warfare as engineers reveal plans for ‘hypersonic’ bomber that can outrun missiles
Breath-taking footage showing the future of military technology, has been released ahead of this year’s Farnborough International Airshow.

Engineers and scientists at BAE Systems and the University of Glasgow have outlined some of their current thinking about military aircraft including the idea that military planes could soon be ‘grown’ in labs and reach hypersonic speeds.

During this century, the scientists and engineers envisage that small Unmanned Air Vehicles (UAVs) bespoke to specific military operations, could be ‘grown’ in large-scale labs through chemistry, speeding up evolutionary processes and creating bespoke aircraft in weeks, rather than years.

A radical new machine called a Chemputer™ could enable advanced chemical processes to grow aircraft and some of their complex electronic systems, conceivably from a molecular level upwards.

This unique UK technology could use environmentally sustainable materials and support military operations where a multitude of small UAVs with a combination of technologies serving a specific purpose might be needed quickly.

In addition, armed forces of the future could be using rapid response aircraft equipped with engines capable of propelling those aircraft to hypersonic speeds.

Such engines could be used to enable very fast commercial aircraft and provide a means of accessing space much more affordably.

Military aircraft flying at speeds of around Mach 5.0 could reach time critical situations in a fraction of the time of current jets by travelling high above the Earth’s surface.

Flying at such speeds and high altitude would allow them to outpace adversary missiles.

“The world of military and civil aircraft is constantly evolving and it’s been exciting to work with scientists and engineers outside BAE Systems and to consider how some unique British technologies could tackle the military threats of the future said Professor Nick Colosimo, a BAE Systems Global Engineering Fellow.

This robot could deliver your pizza someday soon
Starship is a self-driving delivery robot made for the suburbs. It can carry food, groceries, or packages up to two miles at a top speed of four miles an hour. It drives on sidewalks, so it uses cameras and computers to avoid obstacles like pedestrians or animals.

The Bitcoin and Blockchain Technology Explained [Video]

The Bitcoin and Blockchain Technology Explained
A block chain is a transaction database shared by all nodes participating in a system based on the Bitcoin protocol. A full copy of a currency’s block chain contains every transaction ever executed in the currency. With this information, one can find out how much value belonged to each address at any point in history.

Every block contains a hash of the previous block. This has the effect of creating a chain of blocks from the genesis block to the current block. Each block is guaranteed to come after the previous block chronologically because the previous block’s hash would otherwise not be known. Each block is also computationally impractical to modify once it has been in the chain for a while because every block after it would also have to be regenerated. These properties are what make double-spending of bitcoins very difficult. The block chain is the main innovation of Bitcoin.

Honest generators only build onto a block (by referencing it in blocks they create) if it is the latest block in the longest valid chain. “Length” is calculated as total combined difficulty of that chain, not number of blocks, though this distinction is only important in the context of a few potential attacks. A chain is valid if all of the blocks and transactions within it are valid, and only if it starts with the genesis block.

For any block on the chain, there is only one path to the genesis block. Coming from the genesis block, however, there can be forks. One-block forks are created from time to time when two blocks are created just a few seconds apart. When that happens, generating nodes build onto whichever one of the blocks they received first. Whichever block ends up being included in the next block becomes part of the main chain because that chain is longer. More serious forks have occurred after fixing bugs that required backward-incompatible changes.

Blocks in shorter chains (or invalid chains) are not used for anything. When the bitcoin client switches to another, longer chain, all valid transactions of the blocks inside the shorter chain are re-added to the pool of queued transactions and will be included in another block. The reward for the blocks on the shorter chain will not be present in the longest chain, so they will be practically lost, which is why a network-enforced 100-block maturation time for generations exists.

These blocks on the shorter chains are often called “orphan” blocks. This is because the generation transactions do not have a parent block in the longest chain, so these generation transactions show up as orphan in the listtransactions RPC call. Several pools have misinterpreted these messages and started calling their blocks “orphans”. In reality, these blocks have a parent block, and might even have children.

Because a block can only reference one previous block, it is impossible for two forked chains to merge.

Drones can collaborate to build architectural structures [Video]

Drones can collaborate to build architectural structures
Architect and researcher Ammar Mirjan explains how drones could be programmed to construct buildings in the first of two movies about the use of unmanned aerial vehicles in architecture.

In 2012, Swiss architecture firm Gramazio Kohler Architects and roboticist Raffaello D’Andrea collaborated with ETH Zürich to program a fleet of drones to lift and stack thousands of polystyrene bricks at the FRAC Centre in Orléans, France.

The Pigeon Patrol Flies Over London [Video]

The Pigeon Patrol Flies Over London
In London this Monday, pigeons wearing small backpacks with pollution sensors and GPS trackers inside them flew around the city detecting its current pollution levels. DigitasLBI, a marketing company, produced this project. The pigeon’s backpacks were made by Plume Labs and can monitor ozone and volatile compounds as well as nitrogen dioxide. The Pigeons are known as the “Pigeon Air Patrol,” and this whole entire stunt is meant to draw the publics’ eye to the decrease in air quality London has experienced over the past few years.
