A team of Leiden astronomers has managed to calculate the first 100 million years of the history of the Oort cloud in its entirety. Until now, only parts of the history had been studied separately. The cloud, with roughly 100 billion comet-like objects, forms an enormous shell at the edge of our solar system. The astronomers will soon publish their comprehensive simulation and its consequences in the journal Astronomy & Astrophysics.

The Oort cloud was discovered in 1950 by the Dutch astronomer Jan Hendrik Oort to explain why there continue to be new comets with elongated orbits in our solar system. The cloud, which starts at more than 3000 times the distance between the Earth and the Sun, should not be confused with the Kuiper belt. This is the rim of rock, grains and ice in which the dwarf planet Pluto is located and which orbits relatively close to the Sun at about 30 to 50 times the Earth-Sun distance.

“Because of this male-specific effect, we investigated the effects of MPH through the paternal line and observed the same behaviors in several generations of their descendants not directly administered the drug.”

An ancient capital, lost under the sand for more than 3400 years, may hold the answer to one of Egyptian history’s greatest mysteries.

Summary: Researchers have identified significant differences in gene activity between the anterior and posterior areas of the hippocampus. Genes associated with depression and other mood disorders are more active in the anterior hippocampus, while genes linked to cognitive disorders, such as ASD, are more active in the posterior hippocampus.

A study of gene activity in the brain’s hippocampus, led by UT Southwestern researchers, has identified marked differences between the region’s anterior and posterior portions.

“The world’s first purchase agreement for net-zero carbon supersonic aircraft marks a significant step toward our mission to create a more accessible world,” said Boom CEO Blake Scholl in a statement.

The planes, which will fly twice the speed of current passenger jets, are expected to be rolled out in 2025, take flight in 2026, and start carrying passengers in 2029.
