Taking a flying jump

... results imply that there could be a simple neural solution that "answers" questions within what is essentially a reflex arc. ...

Nanoscale method for investigating living systems

...George Kumar, found that by applying voltages to a solution of quantum dots and membranes similar to those of living cells, the dots would be pressed into the membranes. The dots formed rings, which in turn acted as portals in the membranes. These artificial portals or pores could enable a method of investiga...

Tadpole soon to help in the fight against cancer and lymphedema

...ng of this network is thus essential for seeking a solution for these diseases. The search for a suitable model system As far back as in 1627 Gasparo Asellius discovered the lymphatic vessels as 'milky veins'. Yet the lymphatic network has not been studied much until now and is therefore as good as unknown,...

Nanotubes inspire new technique for healing broken bones

...eat broken bones, allowing them to simply inject a solution of nanotubes into a fracture to promote healing. ...e may someday give doctors the ability to inject a solution of nanotubes into a bone fracture, and then wait for the new tissue to grow and heal. Simple single...

Genes linked to treatment resistance in children with leukemia

...dren with these unfavorable genotypes, a potential solution may be using drugs that are not affected by these particular enzymes or increasing the dosage of drugs that are. And, in the future, a simple blood test may be all that's needed to make that determination. "This research showcases a new direction fo...

New law for resolution allows unprecedented sharpness in fluorescence microscopy

...lution limit can be produced without confining the solution itself mechanically. This method may substantially improve the analysis of pharmaceutical active ingredients and protein interactions in cells in future. Original work: [1]Hell, S. W. Strategy for far-field optical imaging and writing without diffr...

A radical solution for environmental pollution

Acid water in East Java threatens biodiversity and local welfare

...ths. Solution According to Lohr, one possible solution for the acidification problem is simply to prevent the crater water from mixing with both neutral rivers. She believes that this could be realised by channelling the flow of acidic water from the crater into the sea, which with its enormous water sur...

Grand Challenges in Global Health initiative funds Yale project

...stigator. Flavell and his team will study a novel solution to a problem facing many vaccine developers. Some of the most promising vaccines for HIV and a range of other diseases are made from weakened versions of the infectious agent. These cannot be studied in human trials unless researchers are confident t...

Oceans turning to acid from rise in CO2

...7 being neutral. Anything that lowers pH makes the solution more acidic. The scientists calculated that over the past 200 years, the pH of the surface seawater has declined by 0.1 units, which is a 30% increase in hydrogen ions. If emissions of CO2 continue to rise as predicted by the Intergovernmental Panel ...

Scientists and engineers apply nature's design to human problems

...ar problem to survive, so every animal is a design solution for a particular problem. "They can provide solutions for more efficient manufacturing and design of materials with new capabilities, for example. These are things the biological world has solved, and if you study them, you have the opportunity to ...

Modifications render carbon nanotubes nontoxic

...ncluded pure, undecorated SWNTs suspended in soapy solution and three forms of nanotubes that were rendered soluble via the attachment of the chemical subgroups hydrogen sulfite, sodium sulfite and carboxylic acid. The cytotoxicity of undecorated SWNTs was 200 parts per billion, which compares to the level o...

Climate change will affect carbon sequestration in oceans, model shows

...tering carbon in the deep ocean is not a permanent solution for reducing the amount of carbon dioxide in the atmosphere, the researchers report. "Carbon dioxide dumped in the oceans won't stay there forever," Jain said. "Eventually it will percolate to the surface and into the atmosphere." ...

How 'Dirt' Could Educate The Immune System And Help Treat Asthma

Scientists develop nanotech-laser treatment that kills cancer cells without harming healthy tissue

..., Stanford researchers found that if they placed a solution of carbon nanotubes under a near-infrared laser beam, the solution would heat up to about 158 degrees F (70 C) in two minutes. When nanotubes were placed inside cells ...

Tropical dry forests receive international recognition

...s can use as policies to save the dry forests. The solution lies in private conservation, says Sanchez-Azofeifa. This tactic means convincing governments to realize the value of conserving tropical dry forest land and in turn, paying the land owners environmental services fees in exchange for a promise the la...

Stem cells' electric abilities might help their safe clinical use

...cell-based therapies, they may provide an ultimate solution to limited donor availability. In an earlier study, Li's lab genetically engineered heart cells derived from human ESCs, suggesting the possibility of transplanting unlimited supplies of healthy, specialized cells into damaged organs. "We do not wa...

New genetic test can detect clam disease

...st Coast and no cure, the researchers say the best solution for shellfishermen and aquaculture operations is to keep infection levels as low as possible and try to keep seed clams free of the disease. One possible remedy may be rotating shellfish crops, much like farmers do on land. ...

'Nanospheres' that block pain of sensitive teeth

...aterial called hydroxyapatite could be a long term solution or cure for sensitive teeth. Sensitive teeth or 'dental hypersensitivity' is a condition that arises when the dentine of the tooth is exposed. The dentine is made up of thousands of tiny fluid-filled channels which radiate outwards from the nerve en...
