The fixed idea that DNA is only a molecule that stores genetic information is being challenged. KAIST researchers have developed a technology that controls the chemical environment around catalysts at the nanometer scale by designing DNA sequences—the arrangement of A, T, G and C that make up genetic information. The team has presented a new catalyst platform that can improve hydrogen production efficiency and increase the yield of desired chemical products by designing DNA much like writing a computer program.

The carefully arranged Neolithic remains show signs of skillful skull removal. The post 77 headless skeletons found in a field date back 7,000 years appeared first on Popular Science.

Honeybees routinely travel up to 2 miles (3 km) from their hive in search of food before returning home, with remarkable accuracy. Relative to body size, this is comparable to a human traveling hundreds of miles and finding their way back without a map, compass, GPS, or smartphone. Despite possessing brains smaller than a sesame seed, bees accomplish this feat with astonishing efficiency. Now, researchers have adapted those same biological principles into a drone navigation system that can guide lightweight flying robots home using just 42 KB of memory.Continue ReadingCategory: Drones, Consumer Tech, TechnologyTags: Delft University of Technology, Navigation, Bees, Biomimicry

A holy grail of environmental policy is an economy that delivers prosperity without requiring the ever-increasing consumption of raw materials.

An English collector who acquired ten of the drawings at an auction loaned them to the Liverpool Beatles Museum for a temporary exhibition

How do bacteria regulate the production of their proteins? Researchers at the University of Hamburg, in collaboration with international partners, have now demonstrated how small protein building blocks, known as peptides, specifically influence bacterial protein production. The findings have been published in two articles in the journal Nature Communications.

Researchers have demonstrated the ability to use van der Waals forces to tune the physical and electronic properties of ferroelectric thin films. The work opens the door to new techniques for engineering materials for use in smaller, more energy efficient electronic devices.

Using a novel simulation model based on machine learning, an international research team at GSI/FAIR has succeeded in gaining a deeper understanding of element formation in stellar events such as neutron star mergers. For the first time, the scientists used deep learning with a neural network to model the energy release during r-process nucleosynthesis in hydrodynamic simulations. The results are published in the journal Physical Review D.

Florida State University physicists are part of a team that has discovered unusual superconducting states in parts of graphene, with the potential to drive unexpected quantum technologies.

Picture a surgical robot that can move, cut tissue, release drugs, grip and store samples, and wirelessly generate heat. You most likely didn't imagine a robot that can fit in your hands. Yet, scientists have created a 5-in-1 robot that fits right on your fingertip!Continue ReadingCategory: Robotics, EngineeringTags: Nanyang Technological University, Drug delivery, Surgical robot

Agriculture today is a massive, globally interconnected industry. That interconnectivity has brought jobs and varied foods to people who might not otherwise be able to access them.

Assistant Professor Haocun Yu is something of a scientific diplomat. In a recent Physical Review Letters publication, she and her colleagues show how a tabletop experiment can bring together two bedrock physics theories that have never been fully reconciled.

Pour out a bottle of Head & Shoulders for Ivan Reitman's Evolution on its 25-year anniversary.

Indonesia is home to the world's largest and most biodiverse coral reef system, spanning more than 32,000 square kilometers across the archipelago. Just like what is happening globally, these reefs are now bearing the brunt of a warming ocean.

Researchers in China recently uncovered a quantum-inspired rule governing how sound is scattered by certain physical properties of a material. Their research, published in Physical Review Letters, may lead to the ability to design materials with optimal, broadband sound blocking.
