NIST publishes a beginner’s guide to DNA origami

Collage shows some of the techniques and designs employed in DNA origami. Credit: K. Dill/NIST In a technique known as DNA origami, researchers fold long strands of DNA over and over again to construct a variety of tiny 3-D structures, including miniature biosensors and drug-delivery containers. Pioneered at the California Institute of Technology in 2006, […]

Which came first, sleep or the brain? — ScienceDaily

Stay awake too long, and thinking straight can become extremely difficult. Thankfully, a few winks of sleep is often enough to get our brains functioning up to speed again. But just when and why did animals start to require sleep? And is having a brain even a prerequisite? In a study that could help to […]

Gene therapy strategy found effective in mouse model of hereditary disease TSC

BOSTON – Patients with tuberous sclerosis complex, a genetic disorder characterized by the growth of noncancerous tumors in multiple organs of the body, have limited treatment options. A team led by investigators at Massachusetts General Hospital (MGH) has now shown that gene therapy can effectively treat mice that express one of the mutated genes that […]

So far, efforts to protect and restore nature on a global scale have failed spectacularly Global leaders will try to reignite international environmental diplomacy on Monday, with a biodiversity summit that launches a critical year for efforts to stem the devastating effects of global warming and species loss. Momentum on climate […]

Nanocrystals that eradicate bacteria biofilm — ScienceDaily

The COVID-19 pandemic is raising fears of new pathogens such as new viruses or drug-resistant bacteria. To this, a Korean research team has recently drawn attention for developing the technology for removing antibiotic-resistant bacteria by controlling the surface texture of nanomaterials. A joint research team from POSTECH and UNIST has introduced mixed-FeCo-oxide-based surface-textured nanostructures (MTex) […]

Neptune’s bumpy childhood could reveal our solar system’s missing planets

This image was taken by Voyager 2, and features its Great Dark Spot and a bright moving spot colloquially called Scooter. (NASA/JPL/) The modern solar system spins serenely, the planets locked in seemingly eternal circles around the sun. But it wasn’t always so. This tranquility appears to have emerged only after a gladiatorial period of […]
