Antioxidant Defense in the Toughest Animals on the Earth: Its Contribution to the Extreme Resistance of Tardigrades

by Keith Cowing

Tardigrades are unique among animals in their resistance to dehydration, mainly due to anhydrobiosis and tun formation. They are also very resistant to high-energy radiation, low and high temperatures, low […]

Insights Into The Synthesis, Engineering, And Functions Of Microbial Pigments In Deinococcus Bacteria

by Keith Cowing

The ability of Deinococcus bacteria to survive in harsh environments, such as high radiation, extreme temperature, and dryness, is mainly attributed to the generation of unique pigments, especially carotenoids.

Optimizing Photosynthetic Light-harvesting Under Stars: Simple And General Antenna Models

by Keith Cowing

In the next 10–20 years, several observatories will aim to detect the signatures of oxygenic photosynthesis on exoplanets, though targets must be carefully selected. Most known potentially habitable exo-planets orbit […]

Influence Of Upstream Solar Wind On Magnetic Field Distribution In The Martian Nightside Ionosphere

by Keith Cowing

This study is led by Postdoctoral researcher Jiawei Gao from IGGCAS. Unlike Earth, Mars lacks a global dipolar magnetic field; the planet does have locally distributed crustal magnetic fields.

Life in the Bubble: How A Nearby Supernova Left Ephemeral Footprints On The Cosmic-ray Spectrum And Indelible Imprints On Life

by Keith Cowing

The Earth sits inside a 300pc-wide void that was carved by a series of supernova explosions that went off tens of millions of years ago, pushing away interstellar gas and […]

Magnetic Fields in a Sample of Planet-hosting M Dwarf Stars from Kepler, K2, and TESS Observed by APOGEE

by Keith Cowing

Stellar magnetic fields have a major impact on space weather around exoplanets orbiting low-mass stars. From an analysis of Zeeman-broadened Fe I lines measured in near-infrared SDSS/APOGEE spectra, mean magnetic […]

The Time Evolution Of The Ultraviolet Habitable Zone

by Keith Cowing

For stars hosting Circumstellar Habitable Zone (CHZ) exoplanets, we investigate the time-evolution of their ultraviolet habitable zone (UHZ), the annular region around a star where an exoplanet could experience a […]
