ROBOTS regenerate: Machines made of DNA show signs of LIFE – and can eat and grow Science | news

As technology continues its exponential evolution, the boundaries between man and machine begin to blur. Cornell University scientists have created the framework of what is considered possible by building machines of DNA that have the key characteristics that must be considered alive. Researchers at the innovative project have shown Express.co.uk how their "lifelike" biomaterial is capable of metabolism, assembly, and …

A story of the crusades as told by the Crusader DNA

This image shows the crusader bones found in a tomb in Sidon, Lebanon. Picture credits: Claude Doumet-Serhal History can tell us much about the Crusades, the series of religious wars between 1095 and 1291, in which Christian invaders conquered the Middle East. The DNA of nine 13th century crusaders buried in a pit in Lebanon shows that there is more …

Skeleton DNA reveals surprising backgrounds of Crusader soldiers

The right upper teeth of the newly discovered species Homo luzonensis. The teeth are smaller and simpler than those of the other Homo species. Towering and battle-scarred, Scotty is the largest Tyrannosaurus rex in the world and the largest dinosaur skeleton ever found in Canada. Researchers discovered unknown species at the Qingjiang Fossil Site on the banks of the Danshui …

Scientists developed a CRISPR tool that removes longer pieces of DNA

This new technique uses CRISPR-Cas3, while most of the work we've seen so far has been done with CRISPR-Cas9. The tool uses a riboprotein complex known as Cascade to target it, and an enzyme called Cas3 to break down the DNA. This allows it to move across several ten-kilobase DNA segments, breaking up genetic material. This would allow scientists to …

Tiny barcode barcodes help researchers identify DNA molecules

"The idea is that everything has its own heartbeat," said Shalin Shah, the main author of the newspaper, a Ph.D. Student of Electrical Engineering and Computer Engineering at Duke University. The technique invented by Shah, together with Duke computer science professor John Reif and postdoctoral fellow Abhishek Dubey of the Oak Ridge National Laboratory, would allow researchers to identify thousands …

DNA in a clay pipe illuminates the life of an enslaved woman

Schablitsky et al. 2019 Smoking pipes were so common in the years 1700 and 1800 that it is not particularly remarkable to find fragments of them in the archaeological sites of the early days of the United States. But Maryland Transportation Chief Julie Schablitsky examined a broken pipe trunk from the bottom of the Belvoir Plantation slave area in Maryland. …

Microsoft device stores digital information as DNA

In its first run, the $ 10,000 prototype "HELLO" turned into DNA. The device first encoded bits (1 and 0) in DNA sequences (A, C, T, G). Then it synthesized the DNA and stored it as a liquid. Next, the stored DNA was read from a DNA sequencer. Finally, the decoding software has translated the sequences back into bits. The …

Finally! A DNA Computer That Can Actually Be Reprogrammed

DNA is supposed to rescue us from a computing rut. But there's a problem: The molecular circuits built so far have no flexibility at all. Today, using DNA to compute it's like having a new computer out of a new hardware, says computer scientist David Doty. So Doty, a professor at UC Davis, and his colleagues put what was in …
