Art and music for the birds

...ck, country, and jazz for local birds. Demaray’s concept of art for the birds hatched from a conversation with co-creator John Walsh, a video artist, who sent Demaray sounds made by the catbird, an avid appreciator of human noise. The Rutgers-Camden scholar makes art that interacts with natural surrounding...

More recycling on the farm could reduce environmental problems

...s groundwater. Yet despite similarities, Pearson's concept of regenerative agriculture is distinct from organic farming; for example, regenerative agriculture could use some chemically treated fertilizer and would exploit robotic systems. The approach would entail more use of human labor, which is costly,...

Mimicking how the brain recognizes street scenes

...eems to work on realistic street scene images is a concept proof that the activity of neurons as measured in the lab is sufficient to explain how brains can perform complex recognition tasks." Making it More Useful The model used in the street scene application mimics only the computations the brain u...

Yale biologists 'trick' viruses into extinction

...ction," said senior author Turner. "We proved the concept using a non-human virus, and variants of the bacteria cells it infects." In ecology, a habitat that supports population growth is termed a "source," whereas a non-supportive habitat is a "sink." This study reported on the success of phi-6 virus po...

Homing pigeons get their bearings from their beaks

...e a universal feature of all birds? Equally, this concept might not only exclusively apply to birds, since it has been shown that many animals display behavior that is modified or controlled by the Earth’s magnetic field. The meaning of these minute iron oxide crystals goes farther than their amazing abi...

Ultrathin films deliver DNA as possible gene therapy tool

...edures to open blocked arteries. While similar in concept to currently available drug-coated stents, Lynn's devices could offer additional advantages. For example, Lynn hopes to deliver genes that could prevent the growth of smooth muscle tissue into the stents, a process which can re-clog arteries, or tha...

Genomics throws species definition in question for microbes

The acquisition of draft-quality genome sequences for all type strains to help advance the integration of genomic information into our understanding of microbial diversity and enable researchers to map phenotypes to genomes. ...

Brain works more chaotically than previously thought

...e with which they are connected via synapses. This concept is the basis of the notion that neuronal information in the brain, somewhat like electricity in a computer, only spreads directionally in the brain, following specific ordered circuits. Too much glutamate is the death of cells There is, howev...

'Exercise pill' switches on gene that tells cells to burn fat

...turned on before birth. While a dramatic proof of concept that metabolic engineering is a potentially viable approach, it offers no help to an adult whose muscles are already formed and who now would benefit greatly from having more active, fat-burning muscles. That is why the potential of chemical met...

Bacteria in small sea life yield new way to make potential cancer drugs

...esting against human diseases. "This proves the concept works," Schmidt said. "We can extract bacteria from animals, take DNA from the bacteria, and produce compounds." Now that they've shown compounds can be synthesized from DNA, the researchers want to figure out how to produce greater quantities of ...

Weighty viruses

...A team led by Huan-Cheng Chang has developed a new concept to attain higher precision. In order to determine their mass, viruses must first be converted to the gas phase, given an electric charge, and accelerated in an electric field. However, this process must leave the viruses intact. The researchers thus ...

Transplanted photoreceptor precursor cells restore visual function in mice with retinal degeneration

...s that he will soon be able to investigate how the concept of transplanting photoreceptor precursors can be adapted to the human retina. "Perhaps within the next five years we will begin to see the first steps toward retinal cell transplants for people with blinding eye disease," says Swaroop. ...

Researchers identify neurons that assign value during learning

... will be of interest to see whether this principal concept of antagonistic neuronal populations mediating positive or negative values during learning holds true for much more complex mammalian brains as well. ...

'Failed' experiment yields a biocontrol agent that doesn't trigger antibiotic resistance

...ings that don't exist in nature. It's a versatile concept that doesn't apply to just one antimicrobial agent." Filutowicz and Burgess, wine enthusiasts who are as comfortable fermenting grapes as they are transforming bacterial plasmids, partnered with students from the Weinert Applied Ventures Program at...

Hopkins scientists link immune response to 'ghost' parasites and severely congested sinuses

... sinusitis, but our study does lend support to the concept that really severe and persistent sinusitis may be a case of a misplaced immune response directed against parasites that are not really there," says study lead author Andrew Lane, M.D., an associate professor at The Johns Hopkins University School of...
