A vicious cycle of DNA damage and repair could be turned against cancer

Researchers at the University of North Carolina (UNC) have discovered that a common lab molecule, used to label DNA, can trigger a runaway process that eventually leads to cell death. But the team says this could have a positive use too, as a potential… Continue reading A vicious cycle of DNA damage and repair could be turned against cancer

Ancient genetic study traces “cold sore” virus back 5,000 years

For people who get cold sores, the virus is with them for life – but how long has the virus itself been with humanity? Scientists from Cambridge have now sequenced the genome of the facial herpes virus, including samples taken from several ancient huma… Continue reading Ancient genetic study traces “cold sore” virus back 5,000 years

First self-assembling DNA nanomotor runs on electricity

Researchers at the Technical University of Munich (TUM) have developed the world’s first electric nanomotors made of DNA. The self-assembling structures can be activated by an electric charge to spin a ratcheting rotor arm.Continue ReadingCategory: Sci… Continue reading First self-assembling DNA nanomotor runs on electricity

DNA typewriter encodes full sentences into living cells

Forget invisible ink – in the future spies could be sending secret messages encoded directly into the DNA of living cells. Researchers at the Howard Hughes Medical Institute (HHMI) have demonstrated a “DNA Typewriter” by encoding full sentences into DN… Continue reading DNA typewriter encodes full sentences into living cells

New gene editing tool reduces errors by nicking DNA not cutting

As important as the CRISPR-Cas9 gene-editing tool has been, it has a relatively high error rate, which can introduce potentially harmful mutations. Researchers in Germany have now developed a more refined tool that reduces errors by nicking DNA instead… Continue reading New gene editing tool reduces errors by nicking DNA not cutting

Wastewater-borne DNA reveals endangered species in fish markets

Despite protective measures being in place, endangered fish species are regularly caught then sold in open markets. And while visually searching them out can be difficult, a new technology could more easily allow authorities to know which species are b… Continue reading Wastewater-borne DNA reveals endangered species in fish markets

Quantum tunneling could drive random DNA mutations, says new study

DNA is known to mutate regularly, for better or worse, driving both evolution and disease. Researchers at the University of Surrey have now found evidence that some of these spontaneous mutations could be caused by the spooky realm of quantum mechanics… Continue reading Quantum tunneling could drive random DNA mutations, says new study

All five of life’s base units have now been found in meteorites

How life on Earth first arose is one of the most profound mysteries of science, and evidence is mounting that the key building blocks may have been delivered to our home planet from space. A new study makes that scenario seem even more likely, as scien… Continue reading All five of life’s base units have now been found in meteorites

Smashing Security podcast #270: Bearded Barbie, EDR scams, and hobbyist crime detectives

Pulchritudinous women with glossy long hair are targeting Israeli officials via Facebook – but why? Scammers have found a new way to gain access to your most sensitive information – but how? And armchair detectives are helping investigating cold cases… Continue reading Smashing Security podcast #270: Bearded Barbie, EDR scams, and hobbyist crime detectives

Global effort realizes first 100% complete sequence of human genome

An international team of scientists has published the first complete, gap-free sequence of the human genome. The new reference genome adds hundreds of millions of base pairs to earlier drafts, filling in some crucial gaps that will improve studies of d… Continue reading Global effort realizes first 100% complete sequence of human genome
