Scientists build tiny “virus traps” out of DNA origami

Researchers at the Technical University of Munich (TUM) have developed a new method to treat viral infections by making traps. The team folded DNA into nano-capsules with specialized binding points inside them, which could grab hold of viruses and rend… Continue reading Scientists build tiny “virus traps” out of DNA origami

CRISPR gene-editing tested in space for first time in DNA damage study

The CRISPR gene-editing tool has been successfully used in space for the first time. Researchers onboard the International Space Station have edited colonies of yeast to study how they repair DNA damage, which could be the first steps towards finding w… Continue reading CRISPR gene-editing tested in space for first time in DNA damage study

Accelerated biological aging seen in prematurely born males

A unique study using epigenetic markers to track biological aging has found prematurely born males, of extremely low birth weight, seem to age more rapidly than prematurely born females with similar birth weight. Why this is the case is unclear but the… Continue reading Accelerated biological aging seen in prematurely born males

DNA provides first-ever confirmed ID of Franklin expedition sailor

Over the years, archeologists have unearthed the remains of members of the infamous Franklin expedition, although it hasn’t been possible to confirm the individuals’ identities. Thanks to DNA analysis, however, scientists have now done so for the first… Continue reading DNA provides first-ever confirmed ID of Franklin expedition sailor

DNA-inspired artificial muscles contract by “supercoiling”

Tiny robots could serve all kinds of useful functions, but shrinking their actuators has proven challenging. Now researchers at the University of Wollongong (UOW) in Australia have made artificial muscles that surpass your puny natural ones, inspired b… Continue reading DNA-inspired artificial muscles contract by “supercoiling”

The mRNA revolution: How COVID-19 hit fast-forward on an experimental technology

Despite the seemingly sudden appearance of this cutting-edge mRNA technology it is, like many scientific innovations, actually the product of decades of piecemeal research. mRNA was first discovered around 60 years ago after scientists worked for years… Continue reading The mRNA revolution: How COVID-19 hit fast-forward on an experimental technology

45,000-year-old human genomes reveal extent of Neanderthal interbreeding

Two new genetic studies have shed light on just how often our ancestors got frisky with Neanderthals. Scientists analyzed the genomes of 45,000-year-old human remains found in caves in Czechia and Bulgaria, including the oldest known genome of a modern… Continue reading 45,000-year-old human genomes reveal extent of Neanderthal interbreeding
