Acoustic Properties of Glacial ice for Neutrino Detection and the Enceladus Explorer

Acoustic Properties of Glacial ice for Neutrino Detection and the Enceladus Explorer

Ultra high energy neutrinos may be observed in ice by the emission of acoustic signals. The SPATS detector has investigated the possibility of observing GZK-neutrinos in the clear ice near the South Pole at the IceCube detector site. To explore other potential detection sites glacial ice in the Alps and in Antarctica has been surveyed for its acoustical properties

New Indexing and Surface Temperature Analysis of Exoplanets

New Indexing and Surface Temperature Analysis of Exoplanets

Study of exoplanets is the holy grail of present research in planetary sciences and astrobiology. Analysis of huge planetary data from space missions such as CoRoT and Kepler is directed ultimately at finding a planet similar to Earth\-the Earth's twin, and answering the question of potential exo-habitability.

Biological Fluorescence as a Temporal Biosignature for Flare Star Worlds

Biological Fluorescence as a Temporal Biosignature for Flare Star Worlds

Habitability for planets orbiting active stars has been questioned. Especially, planets in the Habitable Zone (HZ) of M-stars, like our closest star Proxima Centauri, experience temporal high-ultraviolet (UV) radiation.

The Habitability of Proxima Centauri b I: Evolutionary Scenarios

The Habitability of Proxima Centauri b I: Evolutionary Scenarios

We analyze the evolution of the potentially habitable planet Proxima Centauri b to identify environmental factors that affect its long-term habitability. We consider physical processes acting on size scales ranging between the galactic scale, the scale of the stellar system, and the scale of the planet's core.

Analog DNA Circuit Does Math In A Test Tube

Analog DNA Circuit Does Math In A Test Tube

Often described as the blueprint of life, DNA contains the instructions for making every living thing from a human to a house fly. But in recent decades, some researchers have been putting the letters of the genetic code to a different use: making tiny nanoscale computers.

Life on Earth May Be Early in Cosmic Terms

Life on Earth May Be Early in Cosmic Terms

Why are we now? We know that the universe is roughly 14 billion years old, and that someday it is likely to end -- perhaps because of a Big Freeze, Big Rip or Big Crunch.

Proxima Centauri as a Benchmark for Stellar Activity Indicators in the Near Infrared

Proxima Centauri as a Benchmark for Stellar Activity Indicators in the Near Infrared

A new generation of dedicated Doppler spectrographs will attempt to detect low-mass exoplanets around mid-late M stars at near infrared (NIR) wavelengths, where those stars are brightest and have the most Doppler information content.

Non-Standard Bonding in Base Pairs

A new study provides insight into base pair bonding in artificial DNA polymerase. Researchers focused on a previously unknown base pair: iso-guanine and methyl-pyrimidinone.
