Fifty years after the Apollo 11 Moonwalk, a vexillologist looks at the challenge of planting the flag on the Moon. When Apollo 11 astronauts Neil Armstrong and Buzz Aldrin planted the United States flag on the Moon 50 years ago this month — July 20, 1969, to be exact — it was a team effort. ...
Powering a massive biosphere on Earth, photosynthesis is the light-mediated reaction that converts carbon dioxide and water to carbohydrates and oxygen. About 2.3 billion years ago, this reaction led to the dramatic oxygenation of Earth’s atmosphere. Evidence exists for oxygen-releasing photosynthesis evolving much earlier — perhaps as early as 3 billion years ago. However, the ...
In recent years, wreckage parts of a 1946 crashed aircraft of the U.S. Air Force were recovered at the Gauli Glacier. Model calculations by ETH Zurich researchers now show that the fuselage of the aircraft will probably only emerge from the ice in 8 to 16 years. In November 1946, a U.S. Air Force aircraft ...
A determined bunch of scientists set out to map the Moon in preparation for the Apollo landings, but that was only the beginning. A new field of science blossomed, and UA scientists have been involved in nearly every U.S. space mission since expanding out to the Solar System. Here’s a fun thought: Imagine if University ...
For the first time, researchers at the University of Michigan have detected bromine atoms in the atmosphere, and in doing so, have confirmed the reaction pathway through which mercury is removed from the atmosphere and enters the ecosystem in the springtime Arctic. Mercury is a particularly toxic pollutant largely emitted through human activities such as ...
New research that uncovers the mechanism behind the newest generation of cancer drugs is opening the door for better-targeted therapy. PARP inhibitors are molecular-targeted cancer drugs used to treat women with ovarian cancer who have the BRCA1 and BRCA2 gene mutations. The drugs are showing promise in late-stage clinical trials for breast cancer, prostate cancer, ...
Artificial gravity has long been the stuff of science fiction. Picture the wheel-shaped ships from films like 2001: A Space Odyssey and The Martian, imaginary craft that generate their gravity by spinning around in space. Now, a team from CU Boulder is working to make those out-there technologies a reality. The researchers, led by aerospace ...
Scientists, led by the USF College of Marine Science, used NASA satellite observations to discover the largest bloom of seaweed in the world called the Great Atlantic Sargassum Belt (GASB), as reported in Science. They confirmed that the belt of brown macroalgae seaweed called Sargassum forms its shape in response to ocean currents, based on ...
Scientists have developed a new method for detecting traces of primordial life in ancient rock formations using potassium. The method relies on searching for high concentrations of potassium in ancient sedimentary rocks, rather than traditional methods that look for carbon, sulfur, or nitrogen—which can appear in ancient rocks through processes unrelated to ancient life. University ...
A report published in the International Journal of Climatology predicts Brisbane, Australia, will become a “difficult place to live” in the next three decades due to soaring temperatures. The extreme heat is also expected to lead to more deaths. Hot Brisbane According to the report, the number of hot days and nights will double in ...
