Bam! Transparent octopus goes opaque in blink of an eye

Image

Two deep-ocean species of cephalopod, an octopus and a squid, can go from transparent to opaque in the blink of an eye, a new study finds.

This impressive camouflage swap is an adaptation that likely keeps the cephalopods safe from two different types of predators. The first are deep-sea creatures that hunt by looking upward for prey silhouetted against the light filtering down through thousands of feet of water. The second are fish that spotlight prey in "biological" headlights. These fish use bioluminescence, their own body-driven light source, to hunt for food...

World's Most Extreme Deep-Sea Vents Revealed: Deeper Than Any Seen Before, and Teeming With New Creatures

ScienceDaily (Jan. 10, 2012) — Scientists have revealed details of the world's most extreme deep-sea volcanic vents, 5 kilometres down in a rift in the Caribbean seafloor.

The undersea hot springs, which lie 0.8 kilometres deeper than any seen before, may be hotter than 450°C and are shooting a jet of mineral-laden water more than a kilometre into the ocean above.

Despite these extreme conditions, the vents are teeming with thousands of a new species of shrimp that has a light-sensing organ on its back. And having found yet more 'black smoker' vents on an undersea mountain nearby, the researchers suggest that deep-sea vents may be more widespread around the world than anyone thought.

Snakes Improve Search-And-Rescue Robots: New Design Uses Less Energy

ScienceDaily (Jan. 19, 2012) — Designing an all-terrain robot for search-and-rescue missions is an arduous task for scientists. The machine must be flexible enough to move over uneven surfaces, yet not so big that it's restricted from tight spaces. It might also be required to climb slopes of varying inclines. Existing robots can do many of these things, but the majority require large amounts of energy and are prone to overheating. Georgia Tech researchers have designed a new machine by studying the locomotion of a certain type of flexible, efficient animal.

"By using their scales to control frictional properties, snakes are able to move large distances while exerting very little energy," said Hamid Marvi, a Mechanical Engineering Ph.D. candidate at Georgia Tech.

Moon-Walk Mineral Discovered in Western Australia

ScienceDaily (Jan. 15, 2012) — The last mineral thought to have been unique to the Moon has been discovered in the remote Pilbara region of Western Australia. It was identified by researchers at The University of Western Australia's Centre for Microscopy, Characterisation and Analysis (CMCA).

Tranquillityite, named after the Sea of Tranquillity* where the Apollo 11 moon-walkers landed in July 1969, was tentatively identified by Professor Birger Rasmussen from Curtin University while studying a polished slice of earthly rock in a scanning electron microscope.

When lunar rocks were first analysed in the 1970s after having been brought to Earth by US astronauts Neil Armstrong, Edwin 'Buzz' Aldrin and Michael Collins, scientists identified three minerals -- armalcolite (after Armstrong, Aldrin and Collins), pyroxferroite and tranquillityite -- that they believed were unique to the Moon.

Armalcolite and pyroxferroite were later found on Earth, but when the CMCA's Dr Janet Muhling and Assistant Professor Alexandra Suvorova and their colleagues from Curtin University, published a recent paper in the journal Geology, they showed for the first time that tranquillityite occurred also on Earth.

Diabetic Mice Provide a Surprising Breakthrough for Multiple Sclerosis Research

ScienceDaily (Jan. 5, 2012) — In humans, active periods of the debilitating disease Multiple Sclerosis (MS) can last for mere minutes or extend to weeks at a time. They're caused by lesions in the brain that develop, partly heal, and then recur. Research into a cure has been difficult, because to date scientists have not been able to replicate these brain recurring symptoms in laboratory mice. That's frustrating because these lab animals, known as animal "models," are the primary tool for research into the mechanisms and potential treatments for MS.

But now, by using a mouse model for diabetes instead, Dr. Dan Frenkel of Tel Aviv University's Department of Neurobiology, working alongside Prof. Yaniv Assaf and Ph.D. student Hilit Levy, may provide a surprising breakthrough for research into a cure for MS. The team has discovered that when mice with Type 1 Diabetes are injected with myelin protein -- the insulating material that coats neurons -- they experience the periods of relapsing and remitting disability associated with brain lesions in humans. And for the first time, they've been able to monitor this brain lesion process using magnetic resonance imaging.

Dr. Frenkel believes his finding will lead to the development of more effective treatments for MS. This research has been published in Experimental Neurology.

Smartphone screens with built-in solar cells

An ingenious researcher at the London Centre for Nanotechnology has managed to squeeze a bunch of photovoltaic (solar power) cells into a very interesting location: Behind your smartphone’s display.

According to Arman Ahnood, who unveiled his findings at the Materials Research Society late last year, only 36% of the light produced by an OLED display is projected straight out; the rest is wasted, either as scattered light or bleeding from the edge of the display. In a fairly basic leap of logic, Ahnood created photovoltaic cells that line the back and sides of OLED screens to capture this wasted light: Voila, free, harvested energy that can then be used to power the phone or charge the battery.

Scientists Produce World's First Magnetic Soap

ScienceDaily (Jan. 23, 2012) — Scientists from Bristol University have developed a soap, composed of iron rich salts dissolved in water, that responds to a magnetic field when placed in solution. The soap’s magnetic properties were shown with neutrons at the Institut Laue-Langevin to result from tiny iron-rich clumps that sit within the watery solution. The generation of this property in a fully functional soap could calm concerns over the use of soaps in oil-spill clean ups and revolutionise industrial cleaning products.

Scientists have long been searching for a way to control soaps (or surfactants as they are known in industry) once they are in solution to increase their ability to dissolve oils in water and then remove them from a system. The team at Bristol University have previously worked on soaps sensitive to light, carbon dioxide or changes in pH, temperature or pressure. Their latest breakthrough, reported in Angewandte Chemie, is the world’s first soap sensitive to a magnetic field.

Ionic liquid surfactants, composed mostly of water with some transition metal complexes (heavy metals like iron bound to halides such as bromine or chlorine) have been suggested as potentially controllable by magnets for some time, but it had always been assumed that their metallic centres were too isolated within the solution, preventing the long-range interactions required to be magnetically active.

New Material to Remove Radioactive Gas from Spent Nuclear Fuel

ScienceDaily (Jan. 24, 2012) — Research by a team of Sandia chemists could impact worldwide efforts to produce clean, safe nuclear energy and reduce radioactive waste.

The Sandia researchers have used metal-organic frameworks (MOFs) to capture and remove volatile radioactive gas from spent nuclear fuel. "This is one of the first attempts to use a MOF for iodine capture," said chemist Tina Nenoff of Sandia's Surface and Interface Sciences Department.

The discovery could be applied to nuclear fuel reprocessing or to clean up nuclear reactor accidents. A characteristic of nuclear energy is that used fuel can be reprocessed to recover fissile materials and provide fresh fuel for nuclear power plants. Countries such as France, Russia and India are reprocessing spent fuel.

Suds Ahoy! Bubble Boats Better Fuel Efficiency

Bubbles aren't just for bath time anymore -- turns out they can also be used to improve the fuel efficiency of cargo ships.

Mitsubishi Heavy Industries calls their Air Lubrication System the first in the world to be applied to a newly built ship, resulting "in a substantial reduction in the ship's resistance."

An array of powerful air pumps on the ship's underbelly blows streams of small bubbles around the ships hull. This creates a pocket of air between the hull and the water, so that a good portion of the hull is not touching the water.
The blanket of bubbles greatly reduces friction, allowing the ship to move faster and more efficiently through the water. Mitsubishi predicts that their air lubrication system can reduce CO2 emissions by 25 percent compared to conventional cargo ships.

Volcanic origin for Little Ice Age

An international research team studied ancient plants from Iceland and Canada, and sediments carried by glaciers.

They say a series of eruptions just before 1300 lowered Arctic temperatures enough for ice sheets to expand.

Writing in Geophysical Research Letters, they say this would have kept the Earth cool for centuries.

The exact definition of the Little Ice Age is disputed. While many studies suggest temperatures fell globally in the 1500s, others suggest the Arctic and sub-Arctic began cooling several centuries previously.
