Scientists find ways to improve cassava, a 'crop of inequality' featured at Goalkeepers

New research has highlighted a crop of inequality called cassava, which has starchy, tuberous roots that sustain more than 500 million people in sub-Saharan Africa, yet cassava has been largely neglected by research and development compared to the staple crops of wealthier regions. Researchers have identified opportunities to improve cassava yields — which have not increased for more than fifty years in Africa.

Tale of two climate crises gives clues to the present

Figuring out what lies ahead for our species and our planet is one of the most pressing and challenging tasks for climate scientists. While models are very useful, there is nothing quite like Earth's history to reveal details about how oceans, animals, and plants respond to and recover from a warming world.

How and when was carbon distributed on Earth?

September 24, 2019 0 Comments Air Quality, Climate, Early Climate, Forest, Global Warming, Human Evolution, Origin of Life

A magma ocean existing during the core formation is thought to have been highly depleted in carbon due to its high-siderophile (iron loving) behavior. Thus, most of the carbon forming the atmosphere and life on Earth may have been delivered by a carbon-rich embryo after the core formation. However, a new high-pressure experiment has shown that previous studies may have overestimated the amount of carbon partitioning to the core.

Bee biodiversity barometer on Fiji

The biodiversity buzz is alive and well in Fiji, but climate change, noxious weeds and multiple human activities are making possible extinction a counter buzzword. Just as Australian researchers are finding colourful new bee species, some of them are already showing signs of exposure to environmental changes.

Is theory on Earth's climate in the last 15 million years wrong?

September 23, 2019 0 Comments Charles Darwin, Climate, Early Climate, Environmental Issues, Fossils, Global Warming, Oceanography, Origin of Life

A key theory that attributes the climate evolution of the Earth to the breakdown of Himalayan rocks may not explain the cooling over the past 15 million years, according to a new study. The study could shed more light on the causes of long-term climate change. It centers on the long-term cooling that occurred before the recent global warming tied to greenhouse gas emissions from humanity.

The population of threatened southern sea otters in Elkhorn Slough, an estuary in Central California, has made a significant comeback as a result of Monterey Bay Aquarium's Sea Otter Program. A newly-published study documents 15 years of research showing how the program helped restore the population in the coastal estuary.

Climate change study finds that maple syrup season may come earlier

Once winter nights dip below freezing and the days warm up above freezing sap begins to flow in sugar maples marking the start of the syrup season. With climate change, daily temperatures are on the rise, which affects sap flow and sugar content. By 2100, the maple syrup season in eastern North America may be one month earlier than it was during 1950 and 2017, according to a new study.
