‘Chemical Clock’ Does Not Seem to Work in Red Giant Stars

An international team of astrophysicists, led by Cristina Chiappini from the Leibniz Institute for Astrophysics Potsdam, has discovered a group of red giant stars for which the ‘chemical clock’ does not work: according to their chemical signature, these stars should be old. Instead, they appear to be young when their ages are inferred using asteroseismology. Their existence cannot be explained by standard chemical evolution models of the Milky Way, suggesting that the chemical enrichment history of the Galactic disc is more complex than originally assumed.

Even Small Coronal Mass Ejections Can Affect Unprotected Planets

While no one yet knows what's needed to build a habitable planet, it's clear that the interplay between the sun and Earth is crucial for making our planet livable - a balance between a sun that provides energy and a planet that can protect itself from the harshest solar emissions. Our sun steadily emits light, energy and a constant flow of particles called the solar wind that bathes the planets as it travels out into space. Larger eruptions of solar material, called coronal mass ejections, or CMEs, occur too, which can disrupt the atmosphere around a planet. On Earth, some of the impact of these CMEs is deflected by a natural magnetic bubble called the magnetosphere.

Penn Looks Forward to Discover New Physics in Second LHC Run

After a two-year hiatus, the Large Hadron Collider at the European Organization for Nuclear Research, or CERN, is gearing up for its second run. The LHC enabled the 2012 discovery of the Higgs boson, which gives mass to all particles, but the world’s most complicated scientific apparatus is far from finished

Holometer May Help Look for Tiny Black Holes and Cosmic Strings That Produce High-Frequency Gravitational Waves

Imagine an instrument that can measure motions a billion times smaller than an atom that last a millionth of a second. Fermilab's Holometer is currently the only machine with the ability to take these very precise measurements of space and time, and recently collected data has improved the limits on theories about exotic objects from the early universe.

Physicists Achieve Interference Between Two Separate Atoms

For the first time, physicists from the CNRS and Université Paris-Sud at the Laboratoire Charles Fabry (CNRS/Institut d'Optique Graduate School) have achieved interference between two separate atoms: when sent towards the opposite sides of a semi-transparent mirror, the two atoms always emerge together.
