Phys.org / 'Ghost tunnels' guide sound waves in one direction while staying invisible to others
Acoustic metamaterials are a fast-evolving family of materials which manipulate sound waves in ever more advanced ways. Now, a team led by Changqing Xu at Nanjing Normal University in China has engineered an acoustic metamaterial, ...
Phys.org / Planets need more water to support life than scientists previously thought
Unfortunately for science fiction fans, desert worlds outside our solar system are unlikely to host life, according to new research from the University of Washington. Scientists show that an Earth-sized planet needs at least ...
Phys.org / 4,000-year-old clay tablets inscribed with magical spells… and beer tabs

Ants are known for many things. They fight, bite and sometimes compete for every crumb. We can now possibly add cleaning services to that list, according to a study published in the journal Ecology and Evolution.
Medical Xpress / A two-way brain interface could help restore walking after paralysis by linking thoughts, robotic legs and sensation
Restoring both walking and sensation to patients with paraplegia is an ambitious goal—but a team of researchers from the Keck School of Medicine of USC, the University of California, Irvine (UCI) and the California Institute ...
Medical Xpress / Biological shield can prevent skin cancer cells from transforming into aggressive metastatic forms
A new study has identified a molecular guardian that keeps skin cells from forgetting what they are and transforming into aggressive, migratory killers. By stabilizing a master genetic switch, this protein shield prevents ...
Phys.org / Extinct ice age giants in Bender's Cave challenge existing climate records for the Edwards Plateau
A recent study by Dr. John Moretti of the University of Texas and local caver John Young uncovered the remains of Ice Age megafauna, revealing an entirely new ecosystem that once thrived on the Edwards Plateau. Among the ...
Medical Xpress / Beyond cell death: The hidden drivers of stem cell aging
As we age, our ability to maintain healthy blood and a strong immune system gradually declines, largely because hematopoietic stem cells (HSCs), the cells responsible for producing all blood cell types, begin to lose their ...
Medical Xpress / Neurobiologists hack brain circuits tied to placebo pain relief
Placebo effects, in which patients experience relief without therapeutic treatment, increasingly have been considered as potentially powerful clinical treatments for ailments such as depression and pain. Yet the neurological ...
Medical Xpress / Chloride ions do more than help neurons fire—they may also help control how genes are expressed
Chloride ions, best known for helping cells maintain fluid balance and electrical stability, may also play a more direct role in regulating brain development than previously thought. In a new study, published in the journal ...
