Charcoal remains could accelerate CO2 emissions after forest fires

Charcoal remains after a forest fire help decompose fine roots in the soil, potentially accelerating CO2 emissions in boreal forests.

Unraveling a Major Cause of Sea Ice Retreat in the Arctic Ocean

Quantitative analysis has evidenced the acceleration system of melting ice: dark water surfaces absorb more heat than white ice surfaces, thus melting ice and making more water surfaces in the Arctic Ocean.

Cloud Formation Suppressed by Biogenic Organic Emissions

Researchers have found evidence that near-ground biogenic emissions of organics suppress cloud formation in cool-temperate forests in autumn, providing clues to how global warming will affect cloud formation and the overall climate.

Equatorial jet in Venusian atmosphere discovered by Akatsuki

Observations by Japan’s Venus climate orbiter Akatsuki have revealed an equatorial jet in the lower to middle cloud layer of the planet’s atmosphere, a finding that could be pivotal to unraveling a phenomenon called superrotation.

New wrapping material enables high quality bioimaging

A nanosheet made of organic polymers has been developed to prevent the drying and deforming of biological samples, thus enabling high-quality imaging under microscopes.Be it cosmology or biology, the advancement of science largely relies on the advancement of measuring instruments and methodology. In the past couple of decades, scientists’ passion to see the invisible has vastly improved microscopes and other equipment resulting in high-resolution images, three-dimensional images, and longer recording times of biological samples. However, current setups do not prevent them from drying and deforming during observations, resulting in blurred images.

Researchers predicted when cholera epidemic in Yemen would peak

Hokkaido University scientists has developed a new mathematical model which accurately forecasted that a devastating cholera epidemic in Yemen would peak by early July, the 26th week of 2017 and the cumulative incidence would be the order of 700-800 thousand cases.

Mosses used to evaluate atmospheric conditions in urban areas

Researchers have developed a method to evaluate atmospheric conditions using mosses (bryophytes) in urban areas, a development that could facilitate broader evaluations of atmospheric environments.Many urban areas face atmospheric problems such as pollution and the heat island effect. With the need to evaluate atmospheric conditions, bioindicators—organisms whose response to environmental changes indicates the health of an ecosystem—have attracted considerable attention. Their merits include being able to evaluate an environment over a wide area at a low cost; detect environmental changes over an extended period; and assess these changes’ effects on the ecosystem. Bryophytes are one such group of plants known to be sensitive to environmental changes, in particular to atmospheric conditions.

Native leech preys on invasive slug?

The giant slug Limax maximus is native to Europe and Asia Minor but has spread widely, being found in North America, South America, North Africa, South Africa, Australia, New Zealand and other regions. The slug is recognized as a notorious pest because it eats agricultural and garden crops.
