Paving the way for new single-molecule electrochemical switches

The degree of twisting of natural helical structures, such as the DNA double-helix, plays an essential role in many important biological functions. Because of their twisted architecture, artificial helices can facilitate ...

New DNA amplification capsule holds promise for fighting diseases

DNA amplification—a molecular "photocopying" technique where genetic material is replicated—has many applications in scientific research, forensic science, and medical laboratories. It is useful for detecting and identifying ...

Genetics denote feral cat source

Feral cats arrived on Dirk Hartog Island in two separate waves, but are now reproductively isolated, according to genetic analysis.

Researchers give mutants another chance

Researchers at Fox Chase Cancer Center have demonstrated that it might be possible to treat genetic diseases, including some forms of cancer, by "rescuing" the misshapen, useless proteins produced by some mutant genes.

Molecule attacks coronavirus in a novel way

Scientists at the University of Bonn and the caesar research center have isolated a molecule that might open new avenues in the fight against SARS coronavirus 2. The active ingredient binds to the spike protein that the virus ...

Technology reveals citrus greening-infected trees

U.S. Department of Agriculture (USDA) scientists are using a technology known as "Fourier transform infrared-attenuated total reflection" (FTIR-ATR) spectroscopy to rapidly identify with 95 percent accuracy citrus plant leaves ...

Refined DNA tool tracks native and invasive fish

Rather than conduct an aquatic roll call with nets to know which fish reside in a particular body of water, scientists can now use DNA fragments suspended in water to catalog invasive or native species.
