The Mississippi River is at record low levels, grounding cargo barges and threatening some towns’ drinking water. USACE is doing damage control.
The drought affecting the Mississippi River has revealed a watery secret – a shipwreck that’s over a hundred years old. The skeleton of the craft emerged in Baton Rouge this summer, thanks to low water levels. Dr. Chip McGimsey, archaeologist for the State of Louisiana, believes the ruins belong to the Brookhill Ferry, which sank in 1915. He says the wreck provides a unique way to explore the past, noting, “It makes history alive in a way that you don’t get any other way.”

Established in 1958, the National Aeronautics and Space Administration (NASA) is an independent agency of the United States Federal Government that succeeded the National Advisory Committee for Aeronautics (NACA). It is responsible for the civilian space program, as well as aeronautics and aerospace research. Its vision is “To discover and expand knowledge for the benefit of humanity.” Its core values are “safety, integrity, teamwork, excellence, and inclusion.”

PARIS—France is falling behind in its plans to return the country’s fleet of nuclear reactors to full power this winter after a rash of outages, raising fears that one of Europe’s key sources of electricity won’t be ramped up to counter Russia’s squeeze on the continent’s energy supplies.
The nuclear fleet was designed to act as the front line of France’s energy security. Since Moscow cut the flow of natural gas to Europe—plunging the continent into its biggest energy crisis since the 1970s oil shock—France’s vaunted nuclear fleet has been about as effective as the Maginot Line, the French fortifications that did little to stop the German invasion during World War II.
Carbenes are among the most adaptable building blocks in organic chemistry, but they may also be dangerously hot. Due to their explosivity in the lab, scientists often avoid using these very reactive molecules.
However, in a new study that was just published in the journal Science, researchers from The Ohio State University describe a new, safer method to turn these short-lived, high-energy molecules into much more stable ones.
“Carbenes have an incredible amount of energy in them,” said David Nagib, co-author of the study and a professor of chemistry and biochemistry at Ohio State. “The value of that is they can do chemistry that you just cannot do any other way.”
People who eat more foods with omega-3 fatty acids in midlife may have superior thinking skills and even better brain structure than people who eat few foods containing the fatty acids. This is according to an exploratory study that was recently published in Neurology, the medical journal of the American Academy of Neurology. Omega-3 fatty acids are found in fish such as salmon, sardines, lake trout, and albacore tuna. They are also found in dietary supplements as well as foods that are fortified with the fatty acids.
“If people could improve their cognitive resilience and potentially ward off dementia with some simple changes to their diet, that could have a large impact on public health.” —
“Improving our diet is one way to promote our brain health,” said study author Claudia L. Satizabal, PhD, of the University of Texas Health Science Center at San Antonio. “If people could improve their cognitive resilience and potentially ward off dementia with some simple changes to their diet, that could have a large impact on public health. Even better, our study suggests that even modest consumption of omega-3 may be enough to preserve brain function. This is in line with the current American Heart Association dietary guidelines to consume at least two servings of fish per week to improve cardiovascular health.”
SpaceX has once again stack Starship 24 with Booster 7 ahead of launch prep tests. It is being prepped for an orbital test flight that will send Ship 24 around Earth once, wrapping up with a splashdown off the Hawaiian island of Kauai.
