Greenhouse gas emissions from African rivers

Tue, 2015-07-21 08:16
Scientists have just completed a large-scale research project conducted over a five-year period on the African continent. The aim of this study was to compile the first greenhouse gas budget of African rivers. The data from this project both complement and challenge previous knowledge of the overall carbon budget for the continent.  

Carbon dioxide pools discovered in Aegean Sea

Thu, 2015-07-16 18:09
The location of the second largest volcanic eruption in human history, the waters off Greece's Santorini are the site of newly discovered opalescent pools forming at 250 meters depth. The interconnected series of meandering, iridescent white pools contain high concentrations of carbon dioxide and may hold answers to questions related to deep-sea carbon storage as well as provide a means of monitoring the volcano for future eruptions.

Tradable Energy Quotas offer fair, effective route to low carbon society

Thu, 2015-07-16 11:10
To achieve public support for a transformation to a low carbon society, politicians would be advised to implement a quantity-based energy quota system, with a fixed and decreasing cap on total use, rather than relying on carbon pricing and taxation mechanisms, according to a new study.

Human-wrought environmental changes impacting crops, pollinators could harm millions

Wed, 2015-07-15 21:22
Changing global environmental conditions caused by humans could negatively impact the health of millions by altering key crops, say two studies. One study found declining food pollinators such as bees could lead to decreased nutrient-rich crops linked with staving off disease. A second study found increasing levels of atmospheric carbon dioxide could lead to lower zinc levels in food and expanded zinc deficiency.

Closer look at microorganism provides insight on carbon cycling

Wed, 2015-07-15 18:33
A research team has reconstructed the crystal structure of BAP, a protein involved in the process by which marine archaea release carbon, to determine how it functioned, as well as its larger role in carbon cycling in marine sediments.

New family of chemical structures can effectively remove CO2 from gas mixtures

A newly discovered family of chemical structures could increase the value of biogas and natural gas that contains carbon dioxide.

Accounting for short-lived forcers in carbon budgets

Wed, 2015-07-15 11:32
New research shows how measures to reduce emissions of short-lived climate forcers can impact global carbon budgets for limiting climate change to below 2 degrees C over pre-industrial levels.

Understanding how climate change may affect human health is a complex task, but scientists are beginning to decipher the relationship.

Air travel and climate: What is the link?

Mon, 2015-07-13 11:32
What impact does a warming planet have on air travel and how might that, in turn, affect the rate of warming itself? A new study has found a connection between climate and airline flight times, suggesting a feedback loop could exist between the carbon emissions of airplanes and our changing climate.

Heat buckyballs to help environment

Mon, 2015-07-13 10:35
Scientists are forging toward tunable carbon-capture materials with a new study that shows how chemical changes affect the abilities of enhanced buckyballs to confine greenhouse gases. In a recent study, they have analyzed the carbon-capture ability of materials created with enhanced C60 molecules.

In Fiery Speeches, Francis Excoriates Global Capitalism

Having returned to his native Latin America, Pope Francis has renewed his left-leaning critiques on the inequalities of capitalism, describing it as an underlying cause of global injustice, and a prime cause of climate change.

In Paris, Scientists Chart Varied Paths to a Sustainable Human Relationship With Earth’s Climate

A Paris meeting ahead of this year’s climate negotiations charted a host of social and technical paths toward a sustainable human relationship with the climate.

Climate Change Is Shrinking Where Bumblebees Range, Researchers Find

Warming temperatures have caused bumblebee populations to retreat from the southern limits of their travels in North America and Europe, according to a new study.

Tropical peatland carbon losses from oil palm plantations may be underestimated

Thu, 2015-07-09 16:24
Peatlands -- waterlogged, organic soils -- have developed over thousands of years as carbon storage systems. In Southeast Asia, peat swamp forests cover about 250,000 square kilometers, a land area about the size of Michigan. Draining tropical peatlands for oil palm plantations may result in nearly twice as much carbon loss as official estimates, according to a new study.

Colourful chemotherapy

Bushwillow: tree of enlightenment

AS A cell prepares to divide, tiny parts of its internal skeleton, known as microtubules, arrange themselves into a spindle that permits its complement of chromosomes to split into two bundles. These bundles will go on to become the nuclei of the daughter cells, so spindle formation is a crucial part of the process of replication. Because out-of-control cell replication is the underlying cause of cancer, developing drugs that interfere with microtubule activity has long been of great interest.

Unfortunately, most drugs developed for the task sabotage the tubules of both cancerous and healthy cells. This causes horrible side effects and means that doctors must use lower doses than would be ideal if killing the cancer were their sole objective. However Oliver Thorn-Seshold and Dirk Trauner, two chemists at Ludwig Maximillian University, in Munich, hope to change this state of affairs. They are trying to develop a tubule-controlling drug that can be switched on and off using light.

The idea of optically controlled chemotherapy is not novel. Several teams have tried enclosing...

Something fishy

THOSE who fret about overfishing and those who fret about genetically modified (GM) food are often one and the same. Such people will soon be impaled on the horns of a dilemma if Johnathan Napier of Rothamsted Research, an agricultural establishment in southern England, has his way. As he and his colleagues describe this week in Metabolic Engineering Communications, they are working on technology that could reduce demand for wild-caught fish considerably. It will do so, though, by feeding farmed fish with GM chow.

Apart from the fact that they taste good, oily fish are also desirable because they are healthy fare. There are many things you can remove from your diet in order to improve cardiovascular fitness, but few that you can add. However DHA and EPA—two molecules often referred to as fish oils—buck this trend. They are known to lower blood pressure, to reduce the risk of heart arrhythmia and to slow the growth of fatty plaques that block arteries.

Fish do not, though, actually make fish oils. They get them from their food. The synthesis is done by single-celled algae and the molecules then pass up the...
