Chemistry resolves toxic concerns about carbon nanotubes
Safety fears about carbon nanotubes, due to their structural similarity to asbestos, have been alleviated following research showing that reducing their length removes their toxic properties.
How 'junk DNA' can control cell development
Researchers from the Gene and Stem Cell Therapy Program at Sydney's Centenary Institute have confirmed that, far from being "junk", the 97 per cent of human DNA that does not encode instructions for making proteins can play ...
A 3-D light switch for the brain
A new tool for neuroscientists delivers a thousand pinpricks of light to a chunk of gray matter smaller than a sugar cube. The new fiber-optic device, created by biologists and engineers at the Massachusetts ...
New high-tech laser method allows DNA to be inserted 'gently' into living cells
(Phys.org) —The applications of gene therapy and genetic engineering are broad: everything from pet fish that glow red to increased crop yields worldwide to cures for many of the diseases that plague humankind. ...
Researchers divide enzyme to conquer genetic puzzle
Rice University researchers have found a way to divide and modify enzymes to create what amounts to a genetic logic gate.
Writing rules for gene-therapy vectors: Researchers compute, then combine benign viruses to fight disease
Rice University researchers are making strides toward a set of rules to custom-design Lego-like viral capsid proteins for gene therapy.
Scientists create nanoscale vehicle to battle cancer without harming healthy cells
(Phys.org)—A tiny capsule invented at a UCLA lab could go a long way toward improving cancer treatment.
Using bioinformatics to trace a president's thoughts
Genetic analysis has led to a variety of important scientific advances from improving disease diagnosis, to developing more effective drugs, to the emergence of gene therapy.
Nanopore opens new cellular doorway for drug transport
A living cell is built with barriers to keep things out – and researchers are constantly trying to find ways to smuggle molecules in. Professor Giovanni Maglia (Biochemistry, Molecular and Structural ...
Scientists develop advanced biological computer
(Phys.org) —Using only biomolecules (such as DNA and enzymes), scientists at the Technion-Israel Institute of Technology have developed and constructed an advanced biological transducer, a computing machine capable of manipulating ...
Chasing a common cold virus
(Phys.org)—As the cold and flu season makes its annual visit, a team of researchers, using Argonne's Advanced Photon Source, continue to complete a detailed map of the human adenovirus—one of several ...
Researchers engineer a hybrid five times more effective in delivering genetic material into cells
Researchers at the Polytechnic Institute of New York University (NYU-Poly) and the NYU College of Dentistry (NYUCD) have developed a carrier in their lab that is five times more efficient in delivering DNA into cells than ...
Overcoming multidrug resistance in cancer cells by silencing genes with RNA
(Phys.org) —Resistance of tumor cells toward multiple cytostatic drugs is a serious problem in cancer treatment. In the journal Angewandte Chemie, a team of Chinese and American researchers has now introd ...
Viruses with integrated gene switch
Scientists of the German Cancer Research Center have developed "RNA switches" which allow them to specifically turn on and off genes in viruses. This will help to enhance regulation of gene therapy and viral therapy of cancer.
