LOICTHE Low Orbit Ion Canon, as it is affectionately called, was described this week in an excellent Gizmodo post:

Shown above is the Ion Protonsequencer, the first benchtop sequencer to offer fast (under 8 hours), affordable (under $1,

We ve made comparable performance improvements while developing other applications based on the formation of an ion depletion zone.

At the junction of the channel an embedded electrode neutralizes some of the chloride ions in seawater to create an ion depletion zone that increases the local electric field compared with the rest of the channel.

The Ion depletion zone prevents salt from passing through which creates fresh water out of salt water.

Using an instrument called a Nanosims 50 ion microprobe which magnifies objects 20000 times graduate student Pierre Haenecour of Washington University in St louis uncovered the single grain in one of the meteorites.

and cells use magnesium to transport calcium and potassium ions across the cell walls. Healthy magnesium levels are key to nerve function muscle contraction heartbeat and healthy bones.

A123systems, which makes rechargeable lithium-ion batteries, raised US$380 million at $13. 50 a share at its initial public offering,

which helps to move chloride ions across cell membranes. Scientists don't know why damage to the gene leads to reduced IGF1 levels,

were developed by start-up firm Ion Torrent in Guilford, Connecticut, which was bought by Life Technologies in August.

The company said that its $149, 000 Ion Proton sequencer, the latest version of the Ion Personal Genome Machine that it launched late in 2010 (see Nature 475,278;

2011), would be able to sequence a genome in a day for $1, 000. Hepatitis C hopefuls Pharmaceutical giant Bristol-myers squibb of New york city has become the latest company to spend billions on the promise of hepatitis C treatments.

Ion Torrent (a subsidiary of Life Technologies. The company, based in Guilford, Connecticut, said on 23 Â July that it would attempt to win the Archon Genomics X Prize,

Battery rescue A123 Systems a leading US manufacturer of lithium-ion batteries for electric vehicles, may have found a solution to its financial woes.

Battery bankruptcy A123 Systems, a leading US Â manufacturer of lithium-ion batteries for electric vehicles, filed for bankruptcy on 16 Â October.

Germany, analysed the spectrum of ultraviolet light emitted by cadmium ions, which is influenced subtly by the shape of the nucleus. Cadmium nuclei are nearly spherical,

this positively charged ion stays put in the soil, sticking to negatively charged clay particles. But then nitrifying soil bacteria go to work,

When this happens the result is in the opposite direction from that of trapped ions

and the sign (direction of the added field today southward) suggests the added ions and electrons have a dominating effect.

The right amount of sodium ions present at a wound site allows for regenerative effects similar to those found in a Salamander.

and escapes into space launch the ion nuclear engines! If black carbon is such a problem why didn't they mention it during NASA flights?

A slim lithium-ion battery usually rechargeable provides the power. An average e-cigarette has about 300 puffs per charge.

and exhibited extensive collinearity across the gene space species-specific genes involved in stress tolerance such as ion transport ATPASE activity transcript factor activity

and found some genes involved in ion transport and homeostasis such as Nhad1 KUP3 and NCL were distinctly upregulated under salt stress.

Lithium-ion battery packs are expected to last the lifetime of the trucks as much as 150000 miles for the drive cycles tested.

Neutral particles from space travel through the electrons and ions in the solar boundary and swap electrons with the plasma inside the boundary to generate another highly energized hydrogen atom called an energetic neutral atom (ENA.

Bismuth ions appear to get into the nanotubes by capillary action and we think we can improve on the process to at least double the contrast maybe more he said.

In particular researchers have struggled to find an electrolyte which conducts ions between a battery's electrodes that won't break down

while allowing ions to pass through). Our innovation has been to identify an unconventional electrolyte/separator system that remains stable at high temperatures Ajayan said.

They may also be suitable for lithium storage for advanced lithium ion batteries he said.

He also studied the structure of the tomato peels to assess their efficiency as biomaterials to remove toxic metal ions and organic pollutants from water.

Zirconium loaded apple peels were found to be able to extract anions such as phosphate arsenate arsenite and chromate ions from aqueous solutions.

#Unzipped nanotubes unlock potential for batteriesresearchers at Rice university have come up with a new way to boost the efficiency of the ubiquitous lithium ion (LI) battery by employing ribbons of graphene that start as carbon nanotubes.

Proof-of-concept anodes--the part of the battery that stores lithium ions--built with graphene nanoribbons (GNRS)

but also help deliver lithium ions to the nanoparticles. Lab tests showed initial charge capacities of more than 1520 milliamp hours per gram (mah/g). Over repeated charge-discharge cycles the material settled into a solid 825 mah/g. It took about two months to go through 50

Lithium ions tend to expand the material they inhabit and the material contracts when they're pulled away.

and lose their ability to store ions. Other labs at Rice have made breakthroughs that help solve the expansion problem by breaking treated silicon into a powder achieving great capacity and many cycles.

When soils are acidic aluminum ions are freed in the soil resulting in toxicity to the plant the scientists write.

By engineering crops to convert aluminum ions into a nontoxic form they said agricultural scientists can now turn these unusable

Haenecour with the Nanosims 50 ion microprobe he used to look for presolar grains in a primitive meteorite.

Hybrid ribbons a gift for powerful batterieshybrid ribbons of vanadium oxide (VO2) and graphene may accelerate the development of high-power lithium-ion batteries suitable for electric cars and other demanding applications.

and in fact vanadium pentoxide has been used in lithium-ion batteries for its special structure and high capacity.

The high-conductivity graphene lattice that is literally baked in solves that problem nicely he said by serving as a speedy conduit for electrons and channels for ions.

and lead author Shubin Yang said they believe that to be among the best overall performance ever seen for lithium-ion battery electrodes.

This unique structure was favorable for the ultrafast diffusion of both lithium ions and electrons during charge

We think this is real progress in the development of cathode materials for high-power lithium-ion batteries Ajayan said suggesting the ribbons'ability to be dispersed in a solvent might make them suitable as a component in the paintable batteries developed in his lab. Co-authors of the new paper are Rice graduate students

and sodium ion transport have evolved rapidly in falcons and also the evolutionary novelties in beak development related genes of falcons and saker-unique arid-adaptation related genes.

The MATE1 gene which was found in triplicate in aluminum-tolerant maize turns on in the presence of aluminum ions

or ions traveling in all directions at supersonic speeds. IBEX cameras measure energetic neutral atoms (ENAS) that form when charged particles become neutralized.

These newly formed pickup ions begin to gyrate around the local interstellar magnetic field just outside the solar system.

The paper Spatial Retention of Ions Producing the IBEX Ribbon by N. A. Schwadron and D. J. Mccomas was published Feb 4 in the Astrophysical Journal.

what were just ions in a solution he said. Then you can skim it off

They then employ cage-like crown ethers to capture the potassium ions that would otherwise dampen the nanotubes'ability to repel one another.

or skeletal material (via calcification) depends on the abundance of carbonate ion. For many organisms calcification declines with increased acidification.

Researchers at JBEI have been cost-effectively deconstructing biomass into fuel sugars by pre-treating the biomass with ionic liquids--salts that are composed entirely of paired ions

Lactic acid-producing bacteria ate away at her bones after death possibly liberating the phosphate ions used to make vivianite Fisher said.
