Asymmetric power boosts extortion in the workplace
Phys.org - latest science and technology news stories - Hace 14 horas
What do profit-driven bosses do if they are not satisfied with an employee's conduct? They use their strategic advantage to blackmail their subordinates: "If you don't want to do the job, I'm sure we'll find somebody else who does". Together with researchers from Harvard University and the Institute of Science and Technology Austria (IST Austria), researchers from the Max Planck Institute for Evolutionary Biology in Plön have found that asymmetrical power encourages extortionate behaviour. Both in a model and an experimental setup, such 'blackmailing' strategies proved successful fo... más »

New route to highly crystalline carbon nitrides for efficient photocatalytic hydrogen generation
Phys.org - latest science and technology news stories - Hace 15 horas
Lunch out of the microwave usually doesn't taste nearly as good as a meal made in a conventional oven. This difference in quality is reversed for graphitic carbon nitride, a catalyst used for generating hydrogen from sunlight. Treatment of a precursor material with microwaves delivers a significantly more crystalline product than conventional thermolysis in an oven. As scientists report in the journal Angewandte Chemie, a catalyst produced in this way is significantly more effective in the generation of hydrogen.

Epigenetic repression suppresses genomic instability
Phys.org - latest science and technology news stories - Hace 15 horas
Susan Gasser and her group at the FMI have found the pathway through which eukaryotic organisms protect their genomes from rearrangements and deletions that arise from repetitive DNA. Human genomes, like those of simple animals like worms, are filled with repeat sequences, many being remnants of viral infections of the distant past. This repetitive DNA is usually kept silent. The transcription of these repeats into RNA was shown by the Gasser laboratory to generate toxic hybrids between RNA and DNA. These aberrant "R-loops" can lead to deletions and insertions, endangering the integ... más »

Climate change could be a greater threat to tropical frogs than deforestation

Changes in climate and land use are expected to reduce the livable area for tropical frogs because these species will increasingly encounter temperatures hot enough to harm their behavior, reproduction and physiology. Climate change, however, may be the most destructive force, according to a recent study involving a researcher from UC Berkeley.
