Bacteria on Mars for improve soil and crop production

New research for adapt bacteria for life on Mars and modify soil in order to enhance crop production.

Could be a great technique for Mars terraformation.

Equation for measure the impact of human activity on the Earth system

Humans are a very important factor in the Earth system...

Co-researcher Professor Will Steffen from ANU said the study for the first time came up with a mathematical equation to describe the impact of human activity on the Earth system, known as the Anthropocene equation.

The importance of subterranean microbes

Here we apply terabase-scale cultivation-independent metagenomics to aquifer sediments and groundwater, and reconstruct 2,540 draft-quality, near-complete and complete strain-resolved genomes that represent the majority of known bacterial phyla as well as 47 newly discovered phylum-level lineages. Metabolic analyses spanning this vast phylogenetic diversity and representing up to 36% of organisms detected in the system are used to document the distribution of pathways in coexisting organisms.

CO2 increasing... and plants cannot help us...

Natural carbon sinks currently absorb approximately half of the anthropogenic CO2 emitted by fossil fuel burning, cement production and land-use change. However, this airborne fraction may change in the future depending on the emissions scenario. An important issue in developing carbon budgets to achieve climate stabilisation targets is the behaviour of natural carbon sinks, particularly under low emissions mitigation scenarios as required to meet the goals of the Paris Agreement.

Blue lakes on antarctic galicers

New detailed research about blue lakes on antarctic  glaciers

Supraglacial lakes are known to influence ice melt and ice flow on the Greenland ice sheet and potentially cause ice shelf disintegration on the Antarctic Peninsula.
