The ability to shift wavelengths means that unlike other lasers--including the solid-state bad boyRaytheon used to knock a UAV out of the air from the deck of a ship earlier this year--an FEL system can adjust that wavelength for a variety of tasks.
Boiling lava beckons them like mindless moths to a naked flame. An incredible video records it all as the daredevil magma men face almost certain death staring down the angry mouth of an exploding hell: the Marum Volcano in Vanuatu near Australia. Th
The French Molten Salt Fast Reactor design with a faster neutron spectrum needs a great deal of starting fissile material (typically 5 to 10 tonnes per GWe) whereas a well moderated (lots of graphite) design is typically 1.5 tonnes and as little as 0
Other rats trained under the same scheme have already helped clear large swathes of land in neighbouring mine-infested Mozambique. Babette, the two-month-old baby, walks unsteadily across the weedy patch followed by two trainers rolling a bar that
World famous inventor Nikola Tesla accidentally set off the explosion while testing a powerful energy broadcasting device. Later, Tesla would make oblique references to the technology he created as a 'death ray' and urged its use as a military weap
Biologists have grown super-size dragonflies that are 15 percent larger than normal by raising the insects, from start to finish, in chambers emulating Earth’s oxygen conditions 300 million years ago.
This bacterium uses an enzyme to make its surroundings less acidic, which is a good environment for them to grow", said Ms Whiffin. The by-product of this reaction is calcium carbonate, or limestone
Human Bot Fly eggs stick to the skin of victims, are hatched by the person's body heat and then the tiny, threadlike maggots chew their way through the skin. The squirming maggots don't stop there. The voracious vermin eat their way deeper. Some ea
In Zimbabwe, where just 700 rhinos remain, anti-poaching units face military-like armed gangs who ruthlessly shoot the animals to hack off the distinctive horns for the Asian traditional medicine market.
More than 2,700 scientists from around the world helped carry out the census in more than 540 expeditions over 10 years. They identified more than 6,000 new species. The discoveries include a blind lobster with a long, spiny, pincer, which lives 3
"Today, we have shown what everyday cars can do," said Hannemann, the chief brain behind DBM Energy, a startup from Berlin that developed the powerful battery pack that made the long trip possible.
Downes continues: “The Garo Hills are a heavily forested and poorly explored area in Meghalaya state in the cool northern highlands of India. The area is internationally renowned for its wildlife, which includes tigers, bears, elephants and Indian
The dolphins seem to walk on water for fun, as it has no other obvious benefit, say scientists working for the Whale and Dolphin Conservation Society. That makes the behaviour a rare example of animals "culturally transmitting" a playful rather
Imagine for a moment a bug bigger than your thumb that's built like a tank and can fly like a fighter jet. Imagine that this bug is relentless killer, single-minded in destroying whatever enemy might threaten it--including you, if it perceives you a
The new work with elephant seals is the first to extract information on the shape of the seafloor -- known as bathymetry -- from new sensors, glued to the animals' heads, which can measure pressure and hence depth. "You can actually map the ocea
astronomer Ragbir Bhathal, a scientist at the University of Western Sydney, claimed to have detected a suspicious pulse of light nearly two years ago, that came from the same area of the galaxy as the location of Gliese 581g, according to the U.K.'s
Scientists at the University of Maryland at College Park have managed to clock a floating piece of graphene at an unbelievable 60 million rpm, far faster than any other macroscopic object yet measured.
ut the most important new revelation is that one of those worlds might be the most Earth-like planet yet identified. "Our findings offer a very compelling case for a potentially habitable planet," said Steven Vogt, an astronomer at UCSC.
A helium shortage means that helium balloons should cost about $100 each.
"Such advanced aliens would perhaps become nomads, looking to conquer and colonize whatever planets they could reach," Hawking said in April as part of science-oriented TV series. "If so, it makes sense for them to exploit each new planet for materia
Mixotrophy is thus proposed to be an early-evolved trait in streptophytes and is suggested to aid survival under stressful conditions and subsidize the production of degradation-resistant cell walls that foster carbon sequestration.
The life-supporting atmosphere Earth's inhabitants currently enjoy did not develop overnight. On the most basic level, biological activity in the ocean has shaped the oxygen concentrations in the atmosphere over the last few billion years. In a p
And earlier this summer researchers in Canada found that the amount of phytoplankton in the ocean has decreased by 40% since 1950 in 8 out of 10 large ocean regions. They ascribed this decline to rising sea-surface temperatures, but add
n we can create propellentless space drive. It appears that the latest research work by James Woodward is validating the existence of the effect.
Scientists studying sunspots for the past 2 decades have concluded that the magnetic field that triggers their formation has been steadily declining.
When the assumption about the neodymium ratio was altered, Jackson and his colleagues knew they should take a look at lava samples from Baffin Island, since those samples contained the correct ratios of helium and neodymium. They discovered that the
"Methane should be abundant on a planet of this temperature and size, but we found 7000 times less methane than what the models predict," says Kevin Stevenson of the University of Central Florida (UCF). Stevenson was lead author of a paper reportin
oye describes seeing layers of oily material — in some places more than 2 inches thick — covering the bottom of the seafloor. "It's very fluffy and porous. And there are little tar balls in there you can see that look like microscopic cauliflower
New evidence supports the idea that we live in an area of the universe that is "just right" for our existence. The controversial finding comes from an observation that one of the constants of nature appears to be different in different parts of the
