Cancer will be Detected with a Simple Blood Test

Illumina has announced the launch of its spin-off Grail, a company dedicated to implement cancer screenings based on blood tests. Grail will use Illumina’s sequencing technology to detect several cancer types by checking the nucleic acids in the blood. The new test would allow early cancer detection in asymptomatic people, dramatically reducing cancer-related death by treating individuals […]

Exosomes Deliver Potent Chemotherapeutic Agent to Cancer Cells

Researchers from the University of North Carolina (UNC) at Chapel Hill have increased the effectiveness of a chemotherapeutic agent 50 fold. The drug, paclitaxel (PTX), was introduced in exosomes that were delivered to cells and mice affected by multidrug resistant (MDR) cancer. The exosomes avoided the drug’s degradation by the immune system. The study was published in […]

A New Technique Makes Nanopore Detection 1000 Times Faster

Researchers from the Imperial College London and the University of Minnesota have developed a technique that accelerates nanopore single-molecule detection 1000 fold. Single-molecule dielectrophoretic trapping, coupled with nanopore sensing, allows detection of molecules even at femtomolar concentrations. The study has been published in the journal Nature Communications. Single molecule detection and identification can have very […]

A Noncoding RNA Regulates Chromosome Number

Researchers from UT Southwestern Medical Center have discovered a gene that keeps the number of chromosomes stable. NORAD (Noncoding RNA Activated by DNA Damage) transcripts are the first case of non-coding RNAs affecting chromosome number, and may have implications in cancer. The study was published in the journal Cell. Joshua Mendell and his team have long been studying […]

The Bucaramanga Giant Who Crossed the Atlantic for Science

Jhon Alex Rodriguez Buitrago is a Colombian structural biologist who left his country to pursue a scientific career that has already taken him to Spain, Belgium and the Czech Republic. In love with evolution, positivism, Richard Dawkins and biophysical techniques, Jhon Alex talks about his life in the countries with the best beer in the world, strategically chosen […]

Metastatic Nanobridges to Take Control of Healthy Cells

Researchers from Brigham and Women’s Hospital (BWM) have discovered a new mechanism used by cancer cells to metastasize. Nanochannels protruding from metastatic cells connect them with healthy cells and allow cancer cells to inject microRNAs that alter the normal cells´ behavior. The study has been published in the journal Nature Communications. Metastasis is the migration […]

Inocuous Nanotechnology-Based Sunscreen Tested in Pig and Mice

Researchers from Yale University funded by the National Institute of Biomedical Imaging and Bioengineering (NIBIB) have developed a sunscreen based on nanoparticles that carry UV-blocking elements. The particles stick to the skin surface without penetrating in the body, thus avoiding toxic effects that can result in cancer. The study has been published in the journal Nature Materials. Currently available […]

3D Map of Human Genome Helps Understand Gene Regulation

Researchers from Whitehead Institute have solved the 3D structure of the human genome in human adult cells and embryonic stem cells (ESCs). Knowing the location of genes and regulatory elements will help to understand gene expression patterns and the influence of nuclear distribution in genetic diseases. The study was published in the journal Cell Stem Cell. Gene […]
