Phys.org / Graphene 'scaffold' recruits bone cells and helps the body regenerate fractures
Experiments conducted in Brazil using laboratory rats have shown that graphene-based structures can act as a powerful ally in bone regeneration. These structures are made of sheets of the chemical element carbon that are ...
Tech Xplore / Air-powered artificial muscles could help robots lift 100 times their weight
Researchers at Arizona State University are developing bio-inspired robotic "muscles" that will enable robots to operate in boiling water, survive abrasive surfaces, bypass impediments that keep their motorized counterparts ...
Phys.org / Engineered E. coli dependency may help contain microbes to defined areas
Take a typical fish out of the water and it won't live long. It gets the oxygen it needs from the water it swims in. In a similar way, scientists are exploring dependency as a method of controlling what microbes can do and ...
Phys.org / Backyard birdwatchers help scientists uncover what hawks really like to eat
Anyone who keeps a bird feeder has likely had the same uneasy thought after seeing a sudden blur of wings in the yard: What was that hawk doing here?
Medical Xpress / Cannabis and tobacco use linked to smaller brain volume
Cannabis and tobacco—whether used on their own or together—can affect the brain's structure. A recent study involving systematic review and meta-analysis of more than 103 studies found that both substances are linked to reduced ...
Phys.org / Silicon quantum computer performs logical operations for the first time
Silicon is ubiquitous in modern electronics, and now it is becoming increasingly useful in quantum computing. In particular, silicon's compatibility with existing chip technology and its long coherence times in silicon-based ...
Phys.org / Novel approach to quantum error correction portends a scalable future for quantum computing
A University of Sydney quantum physicist has developed a new approach to quantum error correction that could significantly reduce the number of physical qubits required to build large-scale, fault-tolerant quantum computers. ...
Phys.org / Spain rethinks how to turn tide against beach erosion
Every winter, storms wipe out swaths of the picturesque Spanish coast, undoing summer reconstruction work and threatening the foundations of the country's vital tourism industry.
Phys.org / A global carbon credit program risks rewarding the wrong behavior
A United Nations-backed framework for protecting tropical forests could allow governments to collect income from carbon credits without advancing forest conservation. The weakness lies in how the program calculates baselines, ...
Phys.org / A universal scheme can verify any quantum state
Quantum technologies, devices that can process, store, or detect information leveraging quantum mechanical effects, could outperform classical devices in some tasks or scenarios. Despite their potential, verifying that these ...
Medical Xpress / Looking back to protect the future: New insights into influenza immunity
A new study from the Peter Doherty Institute for Infection and Immunity shows that seasonal influenza vaccination does more than protect against viruses circulating that year; it can also prime the immune system to respond ...
Phys.org / Rudeness may be rewarded—as a response to rudeness
If you don't have anything nice to say, perhaps it's OK to say it anyway—if responding to someone who has treated you or your team rudely, new Cornell research suggests. Civil responses to disrespectful behavior remain the ...
