Washington, DC— Brown dwarfs are sometimes called failed stars. They’re stars’ dim, low-mass siblings and they fade in brightness over time. They’re fascinating to astronomers for a variety of reasons, but much about them remains unknown. New work from a Carnegie-led team reports the distances of a...

Stanford, CA— With a growing world population and a changing climate, understanding how agriculturally important plants respond to drought is crucial. New work from a team led by Carnegie’s José Dinneny discovers a strategy employed by grasses in drought conditions that could potentially be harnessed to improve crop productivity.

Brown dwarfs are smaller than stars, but more massive than giant planets. As such, they provide a natural link between astronomy and planetary science. However, they also show incredible variation when it comes to size, temperature, chemistry, and more, which makes them difficult to understand, too. New work surveyed various properties of 152 suspected young brown dwarfs in order to categorize their diversity and found that atmospheric properties may be behind much of their differences.

Scientists have looked for different ways to force hydrogen into a metallic state for decades. Metallic hydrogen is a holy grail for materials science because it could be used for superconductors, materials that have no resistance to the flow of electrons, increasing electrical efficiency many times over. For the first time researchers, led by Carnegie’s Viktor Struzhkin, have experimentally produced a new class of materials blending hydrogen with sodium that could alter the superconductivity landscape.

Baltimore, MD— As we age, the function and regenerative abilities of skeletal muscles deteriorate, which means it is difficult for the elderly to recover from injury or surgery. New work from Carnegie’s Michelle Rozo, Liangji Li, and Chen-Ming Fan demonstrates that a protein called b1-integrin is crucial for muscle regeneration. Their findings, published by Nature Medicine, provide a promising target for therapeutic intervention to combat muscle aging or disease.

Washington, DC— Well-understood physical and chemical processes can easily explain the alleged evidence of a secret, large-scale atmospheric spraying program, commonly referred to as “chemtrails” or “covert geoengineering,” concludes a new study from Carnegie Science, University of California Irvine, and the nonprofit organization Near Zero.

Some groups and individuals erroneously believe that the long-lasting condensation trails, or contrails, left behind aircraft are evidence of a secret large-scale spraying program. They call these imagined features “chemtrails.” Adherents of this conspiracy theory sometimes attribute this alleged spraying to the government and sometimes to

Washington, DC—Offering a rare insider analysis of the climate assessment process, Carnegie’s Katharine Mach and colleagues at the Department of Global Ecology examined the writing and editing procedures by which the Intergovernmental Panel on Climate Change creates summaries of their findings for policymakers. Despite recent critiques that these summaries are too difficult for non-experts, Mach and colleagues found them comparable to reference texts in terms of reading comprehension level. Their results are published by Science Advances.

Pasadena, CA—Astronomers, conducting the broadest survey to date of galaxies from about 800 million years after the Big Bang, have found 22 early galaxies and confirmed the age of one by its characteristic hydrogen signature at 787 million years post Big Bang. The finding is the first age-confirmation of a so-called dropout galaxy at that distant time and pinpoints when an era called the reionization epoch likely began. The research will be published in a December issue of the Astrophysical Journal.     

With recent technological advancements, such as the Wide-Field Camera 3 on the Hubble Space Telescope, there has been an explosion of research of the

Pasadena, CA – A nearby spiral galaxy, similar to our own Milky Way, has been discovered to have a disk observed in the ultraviolet (UV) part of the spectrum that is several times larger than in the visible spectrum. The finding suggests that the outer parts of the disk are mostly formed by very young blue stars. The radius of extended UV disk is 28,000 light-years

Washington, D.C. – For the first time, astronomers have measured the day and night temperatures of a planet outside our solar system. The team,* which includes Sara Seager of Carnegie’s Department of Terrestrial Magnetism, revealed that a giant Jupiter-like gas planet orbiting very close to its star is blisteringly hot on one side, and frigid on the other.

The finding, made using NASA's Spitzer Space Telescope, represents the first time that any kind of variation has been seen across the surface of a planet outside our solar system. Previous studies of such planets—known to astronomers as “extrasolar” planets—have described whole-

Superdeep diamonds are  tiny time capsules carrying unchanged impurities made eons ago and providing researchers with important clues about Earth’s formation.  Diamonds derived from below the continental lithosphere, are most likely from the transition zone (415 miles, or 670km deep) or the top of the lower mantle. Understanding diamond origins and compositions of the high-pressure mineral phases has potential to revolutionize our understanding of deep mantle circulation.

Anna Michalak’s team combined sampling and satellite-based observations of Lake Erie with computer simulations and determined that the 2011 record-breaking algal bloom in the lake was triggered by long-term agricultural practices coupled with extreme precipitation, followed by weak lake circulation and warm temperatures. The bloom began in the western region in mid-July and covered an area of 230 square miles (600 km2). At its peak in October, the bloom had expanded to over 1930 square miles (5000 km2). Its peak intensity was over 3 times greater than any other bloom on record. The scientists predicted that, unless agricultural policies change, the lake will continue to experience

Until now, computer models have been the primary tool for estimating photosynthetic productivity on a global scale. They are based on estimating a measure for plant energy called gross primary production (GPP), which is the rate at which plants capture and store a unit of chemical energy as biomass over a specific time. Joe Berry was part of a team that took an entirely new approach by using satellite technology to measure light that is emitted by plant leaves as a byproduct of photosynthesis as shown by the artwork.

The plant produces fluorescent light when sunlight excites the photosynthetic pigment chlorophyll. Satellite instruments sense this fluorescence yielding a direct

Geochemist Steven Shirey is researching how Earth's continents formed. Continent formation spans most of Earth's history, continents were key to the emergence of life, and they contain a majority of Earth’s resources. Continental rocks also retain the geologic record of Earth's ancient geodynamic processes.

Shirey’s past, current, and future studies reflect the diversity of continental rocks, encompassing a range of studies that include rocks formed anywhere from the deep mantle to the surface crust. His work spans a wide range of geologic settings such as volcanic rocks in continental rifts (giant crustal breaks where continents split apart), ancient and present subduction zones

Young investigator Martin Jonikas has broad ambitions: to transform our fundamental understanding of photosynthetic organisms by developing game-changing tools. In the long run, his lab aims to increase photosynthetic efficiency of crops, which could improve food production around the world.

When photosynthesis first evolved, the atmosphere contained much more carbon dioxide and much less oxygen than it does today. As a result, the photosynthetic machinery of many organisms may not be completely optimized for today’s environment.

The protein responsible for fixing carbon dioxide—called Rubisco—worked very well in the Earth’s early atmosphere. As photosynthetic organisms

Distant galaxies offer a glimpse of the universe as it was billions of years ago. Understanding how the Milky Way and other galaxies originated provides a unique perspective on the fundamental physics of cosmology, the invisible dark matter, and  repulsive force of dark energy. Patrick McCarthy uses the facilities at Carnegie’s Las Campanas Observatory to explore the early formation and evolution of galaxies. He is also director of the Giant Magellan Telescope Organization, an international consortium that is building the next generation giant telescope.
