Protein folding

Big Step Forward for Protein Engineering

A group of US and Canadian researchers conducted the largest-scale testing of folding stability for computationally designed proteins. More than 15,000 newly designed small proteins were tested for correlation between folding and function which resulted in significant protein modeling improvements.

DNA molecular scissors

New Cpf1 Molecular Scissors to Take Genomic Editing to the Next Level

CRISPR (Clustered Regularly Interspaced Palindromic Repeats) gene editing technology allows permanent modification of genes within organisms. It is considered a breakthrough in biotechnology ever since its discovery.  Researchers from the University of Copenhagen (Denmark), led by Spanish researcher Guillermo Montoya, now went one step further. They discovered how Cpf1, a new type of molecular scissors, unzip and cleave DNA.

Origin of Conciousness

Have We Found the Origins of Consciousness?

Consciousness has been defined as awareness, a person’s ability to experience and feel, an enigma that defies explanation. The nature of consciousness intrigued philosophers and psychologists for thousands of years. Modern neuroscience is giving some answers that could lighten the physical source of our consciousness and some promising fundamental theories are being established.

Air Pollution Damages Your Heart

Since the Industrial Age fuel exhaustion caused air pollution. When smog accumulates in the air in high enough concentrations, people start to feel unpleasant consequences. According to the World Health Organization, in 2014, 92% of the world population was living in places where the air quality guidelines levels were not met. The situation is especially difficult in China, where citizens often use the word airpocalypse to describe living in the grey world of smog.

DNA qPCR quantification

qPCR Data Analysis Made Easy

Despite the advancement of new molecular biology techniques like ddPCR or  RNAseq, quantitative PCR (qPCR) is still a golden standard for the quantification of nucleic acids, with applications in diagnostics and research. The method is based on real-time monitoring of amplification of the target DNA allowing its quantification (see basics). Yet, for the method to be quantitative, it has to be done properly.
