DNA Nanorobots Are Developed to Fight Cancer Cells in Human Trial

It is hoped by scientists that nanobots built completely of DNA would help save the life of patient with the critically ill leukemia. Such nanobots are designed to identify cancer cells and then kill them, at the mean time; they would do little harm to healthy cells. However, at this […]

DNA Hard Drive Can Preserve Data for a Few Millennia

With inspiration from fossilized bones, scientists have discovered an approach to preservation of data in the form of DNA enclosed in silica. Being released in the recent edition of Angewandte Chemie, such discovery findings could allow digital information to be permanently preserved, or for millions of years. While ancient scrolls […]

DNA Results Indicate Kennewick Man Was Native American

In 1996, two students found Ancient human remains on a river bank in Kennewick, Washington, so the skeleton they discovered was nicknamed as Kennewick Man. The remains was dated back to 9,000 years ago and it is thought to be one of the most complete skeletons unearthed so far in […]

Scientists Turn Bacteria into Genomic Tape Recorders that Store Cells’ Memories

By the means of randomly sequencing its DNA, researchers succeeded in converting the widely seen gut bacterium E. coli into smallest tape recorder in the world. The latest designed microbes were intently engineered so as to document and store memories from their surroundings that could be traced back later. Such concept was […]

The Genome of Domestic Cat Has Been Sequenced

Over the past decade, genome sequencing has taken a big leap forward. Since the first bacterial genome was sequenced in year 1995, we have successfully sequenced thousands of bacterial and hundreds of eukaryotic genomes in recent two decades. Each year, the sequencing process becomes faster and less expensive. Therefore, it […]

Scientists Discover Probable Way to Silence Fear Gene

A group of scientists led by Dr Timothy Bredy at Queensland Brain Institute of University of Queensland, Australia has identified a way to silence the gene responsible for fear. This new study, released in the Proceedings of the National Academy of Sciences, is focused on the processes related with decreasing the […]

The World’s First Ranking Tracks Birds’ Evolutionary Distinctness

The World’s First Ranking Tracks Birds’ Evolutionary Distinctness

A research team including three scientists from Simon Fraser University has released the first ranking of evolutionary distinct birds on the edge of extinction in the world. On such list, there is a cave-dwelling bird whose oil could be used as a lamp and a bird with claws on its […]

First Comprehensive Map of Human Gene Activity Produced

With the joint efforts of the many researchers from some countries, the first comprehensive and detailed map has been produced to explain the operation of the genes across the major cells and tissues of the human being. Such atlas presents a description of the complex networks governing the gene activity, […]

You Are What Your Dad Eats?

-Study Suggests that a Father’s Diet before Conception Plays a Vital Role in Offspring Health For a long time, people pay close attention to pregnant women’s healthy diet – babies spend about 40 weeks in mothers’ belly, sharing nutrition and internal secretion environment with their mothers, so of course mothers […]

New Discovery on Hominin DNA Suggests Link to Mystery Population

New Discovery on Hominin DNA Suggests Link to Mystery Population

Paleontologists gleaned DNA from a 400,000-year old femur from Spain and discovered an unexpected link between Europe’s hominin inhabitants of the time and a cryptic population, the Denisovans, known to have lived much more recently in southwestern Siberia. The DNA sequence, representing the oldest hominin sequence yet published, brings paleontologists […]
