Lab-based mimicry allowed an international team of physicists including Carnegie’s Alexander Goncharov to probe hydrogen under the conditions found in the interiors of giant planets—where experts believe it gets squeezed until it becomes a liquid metal, capable of conducting electricity. To build better models of potential exoplanetary architecture, this transition between gas and metallic liquid hydrogen must be demonstrated and understood.

New work from Carnegie’s Ethan Greenblatt and Allan Spradling reveals that the genetic factors underlying fragile X syndrome, and potentially other autism-related disorders, stem from defects in a cell’s ability to create unusually large protein structures. It turns out that a gene called Fmr1 plays a kind of "helper" role, which boosts the production of critically important large proteins in both neurons and egg cells. Their results explain why Frm1's absence is linked to the most-common form of inherited autism, fragile X syndrome, as well as to premature ovarian failure.

Observatories NASA Hubble Postdoctoral Fellow Maria Drout will receive the tenth Postdoctoral Innovation and Excellence Award (PIE). She was one of four Carnegie astronomers who, along with colleagues from UC Santa Cruz, provided the first-ever glimpse of two neutron stars colliding last August. She was first author on a Science paper, which measured the changing light from that merger to shed light on the origin of the heaviest elements in the universe.. The discovery was widely covered by the media and opened the door to a new era of astronomy.

Washington, DC— When it comes to aerosol pollution, as the old real estate adage says, location is everything.

Aerosols are tiny particles that are spewed into the atmosphere by human activities, including burning coal and wood. They have negative effects on air quality—damaging human health and agricultural productivity.

While greenhouse gases cause warming by trapping heat in the atmosphere, some aerosols can have a cooling effect on the climate—similar to how emissions from a major volcanic eruption can cause global temperatures to drop.  This occurs because the aerosol particles cause more of the Sun’s light to be reflected away from the planet. Estimates indicate that

Washington, DC—Lab-based mimicry allowed an international team of physicists including Carnegie’s Alexander Goncharov to probe hydrogen under the conditions found in the interiors of giant planets—where experts believe it gets squeezed until it becomes a liquid metal, capable of conducting electricity. Their work is published in Science.

Hydrogen is the most-abundant element in the universe and the simplest—comprised of only a one proton and one electron in each atom. But that simplicity is deceptive, because there is still so much to learn about it, including its behavior under conditions not found on Earth.

For example, although hydrogen on the surface of giant planets,

Bernard Burke, distinguished MIT astrophysicist and former staff scientist at Carnegie's Department of Terrestrial Magnetism, died August 5. He was 90. 

Burke, who joined the department's in 1953, was an integral member of its astronomy group until he left to be professor of physics at MIT in 1965, where his work shifted to, among other things, the detection of gravitational lensing. He also played a key role in the development of Very Long Baseline Interferometry (VLBI), which enables high-resolution imaging of cosmic structures. He was elected to the National Academy of Sciences in 1970 and served as president of the American Astronomical Society from 1986 to 1988. He was an

Along with colleagues at UC Santa Cruz, Carnegie’s Anthony Piro, Josh Simon, Maria Drout, and Ben Shappee used the Swope Telescope at our Las Campanas Observatory to discover the light produced by the explosion, pinpointing the origin of a gravitational wave signal less than 11 hours after it was detected by the LIGO Collaboration. They followed the radioactive glow of the debris over the next few weeks, unlocking the secret of how some of the world’s most-valuable elements, such as gold and platinum, are created. Drs.

Adult brain connections are precise, but such precision emerges during critical developmental periods when synapses—the delicate contacts between neurons that relay and store information—are either pruned or grow as part of a learning driven process. Understanding the molecules and mechanisms of this synapse pruning may lead to treatments for developmental disorders and Alzheimer’s disease.

Why create national parks? Although the process of designating new parkland is lengthy and complex, national parks offer ecological, cultural, and economic benefits, while also guaranteeing longterm conservation of fragile ecosystems. Founded by Kristine McDivitt Tompkins and her latehusband, Douglas, Tompkins Conservation and its partners have protected approximately 13 million acres of parkland in Chile and Argentina. Mrs. Tompkins will answer the question of why national parks are a worthwhile investment by drawing on her years as the CEO of Patagonia, Inc., in addition to her more than two decades leading initiatives to rewild and restore biodiversity in South America.

Scientific literacy is now recognized to be crucial for our nation's progress in the 21st century.

The Carnegie Institution, a pre-eminent basic research organization, has fostered the development of scientific knowledge since the early 20th century. For many years, this meant the training of graduate students and postdoctoral fellows in the Institution's laboratories, located in Washington, DC and around the country.

In 1989, Maxine Singer, then president of Carnegie, founded First Light, a Saturday science school for children. This was the start of the Carnegie Academy for Science Education (CASE) whose goal is to encourage interest in science among school children and

Allan Spradling is a Howard Hughes Medical Institute Investigator and director of the Department of Embryology. His laboratory studies the biology of reproduction particularly egg cells, which are able to reset the normally irreversible processes of differentiation and aging that govern all somatic cells—those that turn into non-reproductive tissues. Spradling uses the fruit fly Drosophila because the genes and processes studied are likely to be similar to those in other organisms including humans. In the 1980s he and his colleague, Gerald Rubin, showed how jumping genes could be used to identify and manipulate fruit fly genes. Their innovative technique helped establish Drosophila as

Alexander F. Goncharov's analyzes materials under extreme conditions such as high pressure and temperature using optical spectroscopy and other techniques to understand how matter fundamentally changes, the chemical processes occurring deep within planets, including Earth, and to understand and develop new materials with potential applications to energy.

In one area Goncharov is pursuing the holy grail of materials science, whether hydrogen can exist in an electrically conducting  metallic state as predicted by theory. He is also interested in understanding the different phases materials undergo as they transition under different pressure and temperature conditions to shed light

Cosmochemist Larry Nittler studies extraterrestrial materials, including meteorites and interplanetary dust particles (IDPs), to understand the formation of the Solar System, the galaxy, and the universe and to identify the materials involved. He is particularly interested in developing new techniques to analyze different variants of the same atom—isotopes—in small samples. In related studies, he uses space-based X-ray and gamma-ray instrumentation to determine the composition of planetary surfaces. He was part of the 2000-2001 scientific team to hunt for meteorites in Antarctica.

Nittler is especially interested in presolar grains contained in meteorites and in what they can tell

Staff member emeritus François Schweizer studies galaxy assembly and evolution by observing nearby galaxies, particularly how collisions and mergers affect their properties. His research has added to the awareness that these events are dominant processes in shaping galaxies and determining their stellar and gaseous contents.

When nearby galaxies collide and merge they yield valuable clues about processes that occurred much more frequently in the younger, distant universe. When two gas-rich galaxies collide, their pervasive interstellar gas gets compressed, clumps into dense clouds, and fuels the sudden birth of billions of new stars and thousands of star clusters.
