Mapping the Earth's Interior

Using a new technique originally designed to explore the cosmos, scientists have unveiled structures deep inside the Earth, paving the way for a new map revealing what Earth's interior looks like.

Brice Ménard, an astrophysicist at Johns Hopkins University, reports, "We were finally able to identify the seismic echoes and use them to create a map."

Doyeon Kim, a seismologist at the University of Maryland and co-author on the paper, explains: "Imagine you're outside in the dark. If you clap your hands and then hear an echo, you know that a wall or vertical structure is in front of you. This is how bats echolocate their surroundings."

Using this principle, the team used the Sequencer algorithm to parse through thousands of seismograms for echoes to create a new map showing details of the Earth's mantle, just above the liquid iron core.

Topsfield, MA 01983
O: 978.887.8833 

The June CWiS LIVE online meetings are coming up! Please join us and invite a friend. Here are links for the online meetings. These are also on our website.

Join the women of CWiS for a time of fellowship and discussion about being a "good and faithful servant" in the current socio-political environment. Some questions to consider for discussion include:

+ Are the words we use and the actions we take reflecting our own selfish desires or God's plan and heart?

+ Do you believe defending yourself is important?

+ What does science say about group thinking and systemic thinking?

+ What guidance does the bible provide?

Moving Toward Artificial Photosynthetic Energy

Using a unique combination of nanoscale imaging and chemical analysis, an international team of researchers has revealed a key step in the molecular mechanism behind the water splitting reaction of photosynthesis, a finding that could help inform the design of renewable energy technology.

Vittal K. Yachandra, senior scientist at the Department of Energy's Berkeley Laboratory believes this is a step toward building artificial photosynthetic systems that can produce clean, renewable energy from sunlight.

Researchers from around the world have contributed to this potentially ground-breaking technology. The chemical process of Photosynthesis is now being captured in a “molecular movie” that shows the S2 to S3 transition step, where the first water (as shown in Ox) comes into the catalytic center after the photochemical reaction at the reaction center.
