A surprising analysis of the composition  of gas giant exoplanets and their host stars shows that there isn’t a strong correlation between their compositions when it comes to elements heavier than hydrogen and helium, according to new work led by Carnegie’s Johanna Teske. This finding has important implications for our understanding of the planetary formation process. 

The American Association for the Advancement of Science (AAAS) elected Carnegie molecular biologist Steven Farber and retired biologist and science educator Toby Horn as AAAS fellows. This year 443 members were awarded this honor for their “scientifically or socially distinguished efforts to advance science or its applications.”

The buildup of scar tissue makes recovery from torn rotator cuffs, jumper’s knee, and other tendon injuries a painful, challenging process, often leading to secondary tendon ruptures. New research reveals the existence of tendon stem cells that could potentially be harnessed to improve tendon healing and even to avoid surgery.

Bleached anemones—those lacking symbiotic algae—do not move toward light, a behaviour exhibited by healthy, symbiotic anemones. Published in Coral Reefs, this finding from Carnegie’s Shawna Foo, Arthur Grossman, and Ken Caldeira, along with Lauren Liddell of the NASA Ames Research Center, is a fascinating case study for exploring the concept of control in a symbiotic relationship.

A star traveling at ultrafast speeds after being ejected by the supermassive black hole at the heart of our galaxy was spotted by an international team of astronomers including Carnegie’s Ting Li and Alex Ji. Hurtling at the blistering speed of 6 million kilometers per hour, the star is moving so fast that it will leave the Milky Way and head into intergalactic space.

The discovery of a 13 billion-year-old cosmic cloud of gas enabled a team of Carnegie astronomers to perform the earliest-ever measurement of how the universe was enriched with a diversity of chemical elements.  Their findings reveal that the first generation of stars formed more quickly than previously thought.

What does a gestating baby planet look like? New research in Nature by a team including Carnegie’s Jaehan Bae investigated the effects of three planets in the process of forming around a young star, revealing the source of their atmospheres. “This could really help us understand how the architecture of a planetary system comes to be and maybe even unlock mysteries about the evolution of our own Solar System,” explained Bae.

The intensity of summer algal blooms has increased over the past three decades, according to a first-ever global survey of dozens of large, freshwater lakes. Carnegie’s Jeff Ho and Anna Michalak and NASA’s Nima Pahlevan used 30 years of data from NASA and the U.S. Geological Survey’s Landsat 5 near-Earth satellite and created a partnership with Google Earth Engine to reveal long-term trends in summer algal blooms in 71 large lakes in 33 countries on six continents. Their findings are published in Nature

Pressure improves lead selenide's ability to turn heat into electricity and could potentially be used to create clean energy generators, according to new work from a team that includes Carnegie’s Alexander Goncharov and Viktor Struzhkin published in Nature Materials.

Move over Jupiter; Saturn is the new moon king. A team led by Carnegie's Scott S. Sheppard has found 20 new moons orbiting Saturn. This brings the ringed planet’s total number of moons to 82, surpassing Jupiter, which has 79. The discovery was announced Monday by the International Astronomical Union’s Minor Planet Center. Studying the orbits of these moons can reveal their origins, as well as information about the conditions surrounding Saturn at the time of its formation.

Carnegie astronomer and Vice President of the Giant Magellan Telescope (GMT), Patrick McCarthy, has been appointed as the first Director of the National Science Foundation’s newly formed National Optical-Infrared Astronomy Research Laboratory (NSF’s OIR Lab). McCarthy has been a member of the GMT project since its inception 15 years ago, helping to bring it from a sketch on a napkin to a 100-plus person organization with 12 U.S. and international partners. In 2008, 20 years into his tenure at Carnegie, McCarthy officially expanded his role when he accepted his current leadership position at GMT.

Carnegie biologist Kamena Kostova has been selected for the Director’s Early Independence Award from the National Institutes of Health, which is designed to provide “exceptional junior scientists” with the opportunity to “skip traditional post-doctoral training and move immediately into independent research positions.”

An age-related decline in recovery from muscle injury can be traced to a protein that suppresses the special ability of muscle stem cells to build new muscles, according to work from a team of current and former Carnegie biologists led by Chen-Ming Fan and published in Nature Metabolism.

There is an as-yet-unseen population of Jupiter-like planets orbiting nearby Sun-like stars, awaiting discovery by future missions like NASA’s WFIRST space telescope, according to new models of gas giant planet formation by Carnegie’s Alan Boss described in an upcoming publication in The Astrophysical Journal.  His models are supported by a new Science paper on the surprising discovery of a gas giant planet orbiting a low-mass star.

NASA’s Transiting Exoplanet Survey Satellite (TESS) has for the first time seen the aftermath of a star that was violently ripped apart by a supermassive black hole. Catching such a rare event in action will help astronomers understand these mysterious phenomena.  The observation is reported by a team of astronomers led by Carnegie’s Thomas Holoien, who is a founding member of the international network of telescopes that made the discovery—the Ohio State University based All-Sky Automated Survey for Supernovae (ASAS-SN).

We do not have any event for now.
