Biological computer developed to encrypt and decipher images

Biological computer developed to encrypt and decipher images

Scientists at The Scripps Research Institute in California and the Technion–Israel Institute of Technology have developed a "biological computer" made entirely from biomolecules that is capable of deciphering images encrypted on DNA chips. Although DNA has been used for encryption in the past, this is the first experimental demonstration of a molecular cryptosystem of images based on DNA computing.

Scientists create novel RNA repair technology

Scientists from the Florida campus of The Scripps Research Institute have identified a compound that can help repair a specific type of defect in RNA. The methods in the new study could accelerate the development of therapeutics to treat a variety of incurable diseases such as Huntington's disease, spinocerebellar ataxia, and Kennedy disease.

Scientists find compounds for use in basic research and drug development

Scientists from The Scripps Research Institute have identified a class of compounds that could be a boon to basic research and drug discovery. In a new study, the researchers show the new compounds powerfully and selectively block the activity of a large and diverse group of enzymes known as "serine hydrolases."

Genome of cyanobacteria reveals hidden secrets

Genome of cyanobacteria reveals hidden secrets

An international team of researchers led by scientists at Scripps Institution of Oceanography at UC San Diego has deciphered the genome of a tropical marine organism known to produce substances potentially useful against human diseases.

Newly created synthetic compound shows HIV-fighting potential

Using chemical compounds found in a Japanese plant as a lead and the clever application of ultraviolet light, a Scripps Research Institute team has created a unique library of dozens of synthetic compounds to test for biomedical potential. Already, one of the compounds has shown great promise in inhibiting replication of HIV particles and fighting inflammation.

New method devised to quantify protein changes

A scientist from the Florida campus of The Scripps Research Institute has devised a new method of analyzing and quantifying changes in proteins that result from a common chemical process. The new findings could provide new insights into the effects of a highly destructive form of stress on proteins in various disease models, particularly cancer.

Plants and animals found common ground in response to microbial threats

Plants and animals found common ground in response to microbial threats

Though it’s been at least a billion years since plants and animals shared a common ancestor, they have through the eons shared a common threat in the form of microbes, including bacteria, eukaryotes, and viruses. This has resulted in remarkably similar mechanisms for detecting the molecular signatures of infectious organisms that hold promise for the future treatment of infectious diseases in humans.

Photonic crystals could usher in an age of low-power optical computing

Photonic crystals could usher in an age of low-power optical computing

Photonic crystals are exotic materials with the ability to guide light beams through confined spaces and could be vital components of low-power computer chips that use light instead of electricity. Cost-effective ways of producing them have proved elusive, but researchers have recently been turning toward a surprising source for help: DNA molecules.

Unraveling complex quantum dot-dopamine interactions

Scientists at the Naval Research Laboratory, in conjunction with the Scripps Research Institute, recently reported a detailed study of the interactions of water soluble semi-conductor quantum dots (QDs) with the electro-active neuro-transmitter dopamine.

Better data, better wells

Better data, better wells

Deepwater offshore oil well exploration relies on the collection of electromagnetic signals. The QMax EM3 Receiver (QMax) from Quasar Geophysical Technologies and Scripps Institution of Oceanography uses a new electrode design that overcomes problems with previous receivers.

JEOL to launch world's smallest solid-state NMR probe
JEOL to launch world's smallest solid-state NMR probe

According to JEOL Resonance, a new benchmark for resolution and benchmark will be set with its introduction next week of a new 0.75-mm solid state nuclear magnetic resonance (NMR) probe. The probe is capable of high resolution sample analysis by spinning the sample at 110 kHz, the world's fastest spinning speed for NMR.
