Scientists plan $1.5bn laser strong enough ‘to tear the fabric of space

leave a comment »

A laser powerful enough to tear apart the fabric of space could be built in Britain.

The major scientific project will follow in the footsteps of the Large Hadron Collider and will answer questions about the universe.

The laser will be capable of producing a beam of light so intense that it will be similar to the light the earth receives from the sun but focused on a speck smaller than a pin prick.

Extreme: A laser powerful enough to tear apart the fabric of space could be built in Britain.

Scientists say it will be so powerful they will be able to boil the very fabric of space and create a vacuum.

A vacuum fizzles with mysterious particles that come in and out of existence but the phenomenon happens so fast that no-one has ever actually been able to prove it.

It is hoped the Extreme Light Infrastructure Ultra-High Field Facility would allow scientists to prove the particles are real by pulling the vacuum fabric apart.

Scientists even believe it might help them to prove whether other dimensions actually exist.

This latest experiment will follow the footsteps of the Large Hadron Collider and be the next big scientific experiment.

Professor John Collier, a scientific leader for the ELI project and director of the Central Laser Facility at Rutherford Appleton Laboratory in Didcot, Oxfordshire, said the laser would be the most powerful on earth.

‘At this kind of intensity we start to get into unexplored territory as it is an area of physics that we have never been before,’ he told the Sunday Telegraph.

The ELI ultra-high field laser, which will be completed by the end of the decade, will cost £1bn and the UK is among a number of European countries in the running to house it.

The European Commission has already authorised plans for three more lasers which will become prototypes for the ultra-high field laser.

Scientists hope the laser will also allow them to see how particles inside an atom behave and it is hoped it might be able to explain the mystery of why the universe contains more matter than previously detected by revealing what dark matter really is.

HOW IT WILL WORK

  • The ultra-high field laser will be made up of 10 beams – each more powerful than the prototype lasers.
  • It will produce 200 petawatts of power – more than 100,000 times the power of the world’s combined electricity production but in less than a trillionth a second.
  • The energy needed to power the laser will be stored up beforehand and then used to produce a beams several feet wide which will then be combined and eventually focused down onto a tiny spot.
  • The intensity of the beam is so powerful and will produce such extreme conditions, that do not even exist in the center of the sun.

Genetically engineered mosquitoes pass lethal gene to offspring

leave a comment »

  • Scientists carry out ‘positive’ trial on Cayman Islands
  • New breed of insect could be used to tackle malaria and dengue fever
  • But critics say it could lead to public health problems

Breakthrough or danger? A UK-based research team has found a way of genetically modifying the Aedes aegypti mosquito so they pass on a deadly gene to their offspring

Breakthrough or danger? A UK-based research team has found a way of genetically modifying the Aedes aegypti mosquito so they pass on a deadly gene to their offspring

Serious concerns have been raised over the release of a new breed of disease-fighting mosquito which has been genetically engineered to kill their own offspring.

There are hopes the project could be used to control agricultural pests and tackle deadly insect-borne illnesses such as dengue fever and malaria.

But the research has raised concerns about the possible side-effects on public health and the environment because, once released, the mosquitos cannot be recalled.

A UK-based scientific team revealed there had been positive signs from the first release into the environment of the mosquitoes, which are engineered to pass a lethal gene onto their offspring, killing them before adulthood.

The study team – which includes experts from Imperial College London and the Liverpool School of Tropical Medicine – released batches of modified mosquitoes in an area of the Cayman Islands where the dengue virus-carrying Aedes aegypti mosquito is common.

The study, published in Nature Biotechnology journal, looked at how successfully the lab-reared, genetically modified insects could mate.

About 19,000 mosquitoes engineered in a lab were released over four weeks in 2009 in a 25-acre area on Grand Cayman island.

Based on data from traps, the genetically engineered males accounted for 16per cent of the overall male population in the test zone, and the lethal gene was found in almost 10 percent of larvae.

Those figures suggest the genetically engineered males were about half as successful in mating as wild ones, a rate sufficient to suppress the population.

Luke Alphey, chief scientific officer at Oxitec, the firm which devised the technique, told the BBC: ‘We were really surprised how well they did.

‘For this method, you just need to get a reasonable proportion of the females to mate with GM males – you’ll never get the males as competitive as the wild ones, but they don’t have to be, they just have to be reasonably good.’

HOW MOSQUITOES KILL THEIR OWN CHILDREN

  • The genetic approach used to create the mosquitoes is a system known as tetracycline-controlled transcriptional activation (tTA).
  • The technique is an extension of one successfully used for decades to control or eradicate pests which involves sterilising millions of insects with radiation.
  • But the process has not worked with mosquitoes, partly because the radiation also injures them, making it difficult for them to compete with healthy counterparts for mates.
  • So Oxitec has now created the Aedes aegypti mosquitoes with a gene that will kill them unless they are given the common antibiotic tetracycline.
  • With tetracycline provided in the lab, the mosquitoes can be bred for generations and multiplied.
  • Males are then released into the wild, where tetracycline is not available.
  • They live long enough to mate but their progeny will die before adulthood.

 

Authorities in the Florida Keys hope to carry out an open-air test on the modified insects as early as December after experiencing the region’s first cases of dengue fever in decades.

Dr Alphey said the technique was safe because only males were released as it was only the females that bite people and spread the disease.

But critics say the process is by no means foolproof.

Alfred Handler, a geneticist at the Agriculture Department in Gainesville, Florida, said the mosquitoes can evolve resistance to the lethal gene while being bred for generations in a lab.

Todd Shelly, an entomologist for the Agriculture Department in Hawaii, also said in a commentary published on Sunday by Nature Biotechnology that 3.5per cent of the insects in a lab test survived to adulthood despite presumably carrying the lethal gene.

Also, the sorting of male and female mosquitoes, which is done by hand, can result in up to 0.5per cent of the released insects being female, the commentary said.

If millions of mosquitoes were released, even that small percentage of females could lead to a temporary increase in disease spread, it was reported by the New York Times.

Oxitec and a molecular biologist, Anthony A. James of the University of California, Irvine, say they have developed a solution — a genetic modification that makes female mosquitoes, but not males, unable to fly.

The grounded females cannot mate or bite people, and separating males from females before release would be easier.

The World Health Organisation expects to release guidance on how GM insects should be deployed in developing countries by the end of the year.

Pilotless Boeing aircraft raises prospect manned dogfights 65000ft

leave a comment »

The maiden flight of a revolutionary drone aircraft that can stay in the air for four days at 65,000 feet is just days away.

The Phantom Eye, made by Boeing’s secretive Phantom Works division, is powered by hydrogen and is designed to carry out surveillance and reconnaissance missions while remaining at high altitude. It will produce only water as a by-product.

Its inaugural flight will take place at Edwards Air Force Base in California and is expected to last between four and eight hours.

Boeing also is developing a larger unmanned plane that will stay aloft for more than 10 days and ‘Phantom Ray,’ a fighter-sized UAV that will be a test bed for more advanced technologies, which made its inaugural flight in April.

The drone technologies being developed by Phantom Works mean the day when dog fights take place between unmanned aircraft is getting much closer.

‘Phantom Eye is the first of its kind and could open up a whole new market in collecting data and communications,’ Darryl Davis, president of Boeing Phantom Works, said.

‘It is a perfect example of turning an idea into a reality. It defines our rapid prototyping efforts and will demonstrate the art-of-the-possible when it comes to persistent intelligence, surveillance and reconnaissance.

‘The capabilities inherent in Phantom Eye’s design will offer game-changing opportunities for our military, civil and commercial customers.’

‘It’s exciting to be part of such a unique aircraft,’ said Drew Mallow, Phantom Eye program manager for Boeing.

‘The hydrogen propulsion system will be the key to Phantom Eye’s success. It is very efficient and offers great fuel economy, and its only byproduct is water, so it’s also a “green” aircraft.’

Phantom Eye is powered by two 2.3-litre, four-cylinder engines that provide 150 horsepower each. It has a 150-foot wingspan, will cruise at approximately 150 knots and can carry up to a 450-pound payload.

The floating city that could become the future of life at sea

with one comment

  • Yacht island comes with 11 accommodation decks and four helipads
  • Designed to move on four platforms, each with thrusters to keep it stable

It looks like something straight out of a James Bond film – but a British firm believes this floating building could be the future of life at sea.

With 11 accommodation decks, a 360-degree observation area, four helipads, its own dock, several swimming pools and as much space as a cruise liner, it’s not so much a boat as a city.

Although it certainly does not fit the mould of a yacht, the design, called ‘Project Utopia’, was unveiled to stunned onlookers at the glitzy Monaco Yacht Show.

Fantasy island: As this artist’s impression shows, Project Utopia is more like a floating city than a boat.

Designer BMT Nigel Gee, of Southampton, Hants, has not yet put a figure on how much the floating island might cost to create or what sort of customer would want to buy it.

The boat is designed to float on four platforms, each with thrusters to keep the whole yacht island stable, even in the extreme seas.

Able to move ‘at slow speeds’, it stretches 65m above the sea’s surface, providing visitors to the 13th floor observation deck with panoramic views.

Just below, the top deck of the main accommodation and service spaces – which could house shops, bars and restaurants – would be covered by a retractable canopy.

Yacht Design Director James Roy believes it challenges preconceptions of traditional naval architecture.

He said: ‘Visions of the future are often constrained by familiarity with the present or a reflection on the past.

‘Much is made in today’s design community of starting with a blank sheet of paper yet many, if not all yacht concepts revert back to the traditional form.

‘Because of the perception that a yacht should be a form of transport it becomes an immediate design constraint.

‘Utopia is not an object to travel in, it is a place to be, an island established for anyone who has the vision to create such a place.’

In the middle, a large column plunges down into the water, acting as a mooring system and housing a wet dock providing access from the sea.

James said the design, which has been created in partnership with Yacht Island Design, represents how the firm, which works on yachts, commercial and naval craft, uses state-of-the-art technology to bring innovation to the industry.

He added: ‘Pioneering design ideas such as Utopia are exactly the types of projects that our team excel in.

‘Our forward-thinking approach and unrivalled state-of-the-art engineering experience allows us to work closely with designers, stylists and shipyards, and bring these ideas to life.’

12 new species of frogs discovered in India

leave a comment »

Scientists have found 12 new species of night frogs living in the lush mountains of southwest India, and rediscovered three that had been thought extinct.

Evolution biologist Sathyabhama Das Biju from the University of Delhi says he hopes the discoveries draw attention to amphibians as important indicators of environmental health.

He said Saturday that there are now 336 known frog species in India, and that many are threatened by habitat loss.

Night frogs are hard to find as they come out only after dark and during the monsoon season. Biju and student researchers had to sit in dark tropical forests listening for frog sounds and shining flashlights under rocks and across riverbeds.

The research is published in the latest issue of international taxonomy journal Zootaxa.

The mystery creature that nobody can identify

leave a comment »

If this cute little chap looks a wee bit confused, it’s no wonder.

His big wide eyes stare out at the world around him – which in turn is staring back at him.

Because nobody has seen a creature quite like this one before.

Who am I? The unidentifed animal sitting in his cage after being handed in to Wenling Zoo, in China

Who am I? The unidentifed animal sitting in his cage after being handed in to Wenling Zoo, in China.

With a nose that looks more like a rodent’s but long, pointy paws and white fur dappled with brown and orange, he is quite unique.

And zookeepers at Wenling, in eastern China, who were handed the animal by an anonymous man, have been unable to work out exactly what species he belongs to.

They think they are looking at some strange type of monkey – but other students of nature might recognise the characteristics of a bush baby.

As he sits in his cage, the creature therefore awaits an uncertain fate.

And the zookeepers sit and monitor his development and hopes he grows up into something slightly more recognisable.

Incredible time-lapse video from the International Space Station

leave a comment »

It took Phileas Fogg 80 days to circumnavigate the world but, thanks to the wonders of technology, it is now possible to do it in just a minute.

This whirlwind video tour of the planet is a compilation of time-lapse images shot from the International Space Station (ISS).

James Drake spliced together the images from the ISS, which travels at about 220 miles above the surface, to create the one-minute footage which he posted online – and it has become an internet sensation.

Science teacher Mr Drake used some 600 free-to-access images on the website The Gateway to Astronaut Photography of Earth, and knitted them together so everyone can enjoy the amazing view of North and South America.

The film, which was uploaded on September 15 and has attracted almost 50,000 hits on YouTube, starts over the Pacific Ocean and then moves over North and South America before entering daylight near Antarctica.

Some cities and landmarks can be spied, and they include, in chronological order, Vancouver Island, Victoria, Vancouver, Seattle, Portland, San Fransisco, Los Angeles, Phoenix, various large conurbations in Texas, New Mexico, Mexico City, the Gulf of Mexico, and the Yucatan Peninsula.

Further around lightning can be seen in the Pacific Ocean, before other countries included in the video are Guatemala, Panama, Columbia, Ecuador, Peru, Chile, and the Amazon.

In addition, the Earth’s ionosphere (thin yellow line) and the stars of our galaxy can be made out in the fascinating footage.

The Gateway to Astronaut Photography of Earth, where Mr Drake downloaded the pictures from, has been storing over a million images from space, beginning with the Mercury missions in the early 1960s.

The website’s blurb reads: ‘Our database tracks the locations, supporting data, and digital images for these photographs.

‘We process images coming down from the International Space Station on a daily basis and add them to the 1,118,120 views of the Earth already made accessible on our website.’

The ISS is currently on Expedition 29, and the astronauts will be on the space station until mid-November, when they will be replaced by another crew.

The ISS, a habitable, artificial satellite in low Earth orbit, follows the Salyut, Almaz, Cosmos, Skylab, and MIR space stations, as the 11th space station launched into orbit by humanity.

It serves as a research laboratory that has microgravity environment in which crews conduct experiments in many fields including biology, human biology, physics, astronomy and meteorology.

The station has a unique environment for the testing of the spacecraft systems that will be required for missions to the Moon and Mars.

The station is expected to remain in operation until at least 2020, and potentially to 2028, when some Russian modules will be separated to form the OPSEK space station.

And the European Space Agency estimate that the cost of the station will be €100 billion over 30 years.

On November 2 last year the ISS marked its 10th anniversary of continuous human occupation, and it was launched almost 11 years ago, on October 31, 2000.

At the time of the anniversary, the station’s odometer read more than 1.5 billion statute miles (the equivalent of eight round trips to the Sun), over the course of 57,361 orbits around the Earth.

The 29th expedition crew settled in to their new home for the next couple of months last week, with Mike Fossum commanding and being aided by Satoshi Furukawa and Sergei Volkov.

They will be up there, travelling about 17,000mph – meaning it takes about 91 minutes to orbit the Earth – until mid-November.

The Expedition 29 crew which will continue to support research into the effects of microgravity on the human body, biology, physics and materials.

The trio took over from Expedition 28 last week, and Commander Andrey Borisenko and Flight Engineers Alexander Samokutyaev and Ron Garan – who had spent 164 days in space – landed their Soyuz TMA-21 spacecraft in Kazakhstan a few seconds before midnight on Friday.

The space station and its large solar arrays is the size equivalent of an American football field – including the end zones – and weighs 861,804 pounds (390,908 kilograms), not including visiting vehicles.

The complex now has more liveable room than a conventional five-bedroom house, and has two bathrooms, a gymnasium and a 360-degree bay window.
