Unveiling the Universe’s Earliest Secrets

It's the faintest light, yet it carries information from the beginning of time. A telescope trained on the Antarctic sky has picked up swirling patterns of light believed to be the imprint of the violent expansion of the universe a trillionth of a trillionth of a trillionth of a second after it burst into being.

Cosmologists Report Evidence for Cosmic Inflation

Cosmologists have detected curling patterns in the faint glow of the universe's oldest light that appear to be traces left by cosmic inflation, an exponential expansion of the universe thought to have occurred fractions of a second after the Big Bang, they announced today.

Crystals Ripple in Response to Light

Light can trigger coordinated, wavelike motions of atoms in atom-thin layers of crystal, scientists have shown. The waves, called phonon polaritons, are far shorter than light waves and can be “tuned” to particular frequencies and amplitudes by varying the number of layers of crystal, they report in the early online edition of Science March 7.

The Surface of the Sea is a Sink for Nitrogen Oxides at Night

The surface of the sea takes up nitrogen oxides that build up in polluted air at night, new measurements on the coast of southern California have shown. The ocean removes about 15 percent of these chemicals overnight along the coast, a team of atmospheric chemists reports in the early online edition of the Proceedings of the National Academy of Sciences the week of March 3.

Clouds seen circling supermassive black holes

Astronomers see huge clouds of gas orbiting supermassive black holes at the centers of galaxies. Once thought to be a relatively uniform, fog-like ring, the accreting matter instead forms clumps dense enough to intermittently dim the intense radiation blazing forth as these enormous objects condense and consume matter, they report in a paper to be published in the Monthly Notices of the Royal Astronomical Society, available online now.

Source of ‘Moon Curse’ Revealed by Eclipse

Strange events have long been linked to nights of a full moon, though careful scrutiny dispels any association. So, when signals bounced off the lunar surface returned surprisingly faint echoes on full moon nights, scientists sought an explanation in reason rather than superstition. Still, the most compelling evidence arrived during another event that once evoked irrational fears—on a night when Earth's shadow eclipsed the full moon.

Biosynthesis Captured in Motion

Chemists have caught molecules in the act of biosynthesis revealing an animated view of how a fundamental piece of cellular machinery operates. The system they observed, a critical metabolic pathway, generates fatty acids, essential components of fats and structures such as cell membranes. Nature published their findings in the early online edition December 22.

Scientists Solve Mystery of Odd Patterns of Oxygen in Solar System’s Earliest Rocks

Cosmochemists at the University of California, San Diego, have solved a long standing mystery in the formation of the solar system: Oxygen, the most abundant element in Earth’s crust, follows a strange, anomalous pattern in the oldest, most pristine rocks, one that must result from a different chemical process than the well-understood reactions that form minerals containing oxygen on Earth.

Center to Study Impact of Atmospheric Particles from the Sea on Climate Awarded $20 Million by NSF

An innovative program of research and education addressing how interactions between air and sea influence the chemistry of the atmosphere will receive $20 million over the next five years from the National Science Foundation.
