    Earthquakes, floods, tsunamis, hurricanes, and volcanoes—they all stem from the very same forces that give our planet life. It is only when these forces exceed our ability to withstand them that they become disasters. Science and engineering can be used to understand extreme events and to design our cities to be resilient, but we must overcome the psychological drive to normalization that keeps humanity from believing that we could experience anything worse than what we have already survived.

Carnegie’s Andrew Steele is a member of the Rensselaer Polytechnic Institute-led Earth First Origins project, which has been awarded a $9 million grant by NASA’s Astrobiology Program. The five-year project seeks to uncover the conditions on early Earth that gave rise to life by identifying, replicating, and exploring how prebiotic molecules and chemical pathways could have formed under realistic early Earth conditions.

China is the world’s largest producer and consumer of coal. Ambitious Chinese regulations on coal mining that took effect in 2010 have not curbed the nation’s growing methane emissions as intended, says new research from a team led by Carnegie’s Scot Miller and Anna Michalak.

  • Carnegie's Juna Kollmeier and Université de Bordeaux's Sean Raymond kicked off an internet firestorm late last year when they posted a draft of their article about submoons on a preprint server. The online conversation obsessed over the best term to describe such phenomena.  But nomenclature was not the point of Kollmeier and Raymond’s investigation, who set out to define the physical parameters for moons that would be capable of being stably orbited by other, smaller moons.

Washington, DC— Carnegie’s Winslow Briggs, a giant in the field of plant biology who explained how seedlings grow toward light, died on February 11 at Stanford University Medical Center. He was 90.

Briggs joined Carnegie as the Director of the Department of Plant Biology in 1973 after teaching both at Harvard University—where he completed his bachelor’s degree, master’s degree, and Ph.D.—and at Stanford University. He held the position for two decades, establishing himself as a global leader in plant genetics and physiology, publishing landmark research on the molecular mechanisms that plants and other organisms use to sense and respond to light

Scientists still aren't sure how this mountain grew inside of the crater, which has been a longstanding mystery. 

One idea is that sediment once filled Gale Crater and was then worn away by millions of years of wind and erosion, excavating the mountain. However, if the crater had been filled to the brim, the material on the bottom, which

One of our greatest scientific challenges is to effectively understand and make use of the vast amount of data being produced in a variety of fields. Visual data analysis will be among our most-important tools for understanding such large-scale, complex data sets. Visualization facilitates the reasoning process by supporting the human capacity to perceive, understand, and discuss complex data. In this talk, Dr. Johnson will present visual analysis techniques, insights, and examples of how visualization can enable understanding in the fields of biology, astronomy, medicine, and engineering.

He will be joined for a discussion of how data visualization can drive scientific discovery

The Giant Magellan Telescope will be one member of the next class of super giant earth-based telescopes that promises to revolutionize our view and understanding of the universe. It will be constructed in the Las Campanas Observatory in Chile. Commissioning of the telescope is scheduled to begin in 2021.

The GMT has a unique design that offers several advantages. It is a segmented mirror telescope that employs seven of today’s largest stiff monolith mirrors as segments. Six off-axis 8.4 meter or 27-foot segments surround a central on-axis segment, forming a single optical surface 24.5 meters, or 80 feet, in diameter with a total collecting area of 368 square meters. The GMT

Carnegie's Paul Butler has been leading work on a multiyear project to carry out the first reconnaissance of all 2,000 nearby Sun-like stars within 150 light-years of the solar system (1 lightyear is about 9.4 trillion kilometers). His team is currently monitoring about 1,700 stars, including 1,000 Northern Hemisphere stars with the Keck telescope in Hawaii and the UCO Lick Observatory telescope in California, and 300 Southern Hemisphere stars with the Anglo-Australian telescope in New South Wales, Australia. The remaining Southern Hemisphere stars are being surveyed with Carnegie's new Magellan telescopes in Chile. By 2010 the researchers hope to have completed their planetary

In mammals, most lipids, such as fatty acids and cholesterol, are absorbed into the body via the small intestine. The complexity of the cells and fluids that inhabit this organ make it very difficult to study in a laboratory setting. The goal of the Farber lab is to better understand the cell and molecular biology of lipids within digestive organs by exploiting the many unique attributes of the clear zebrafish larva  to visualize lipid uptake and processing in real time.  Given their utmost necessity for proper cellular function, it is not surprising that defects in lipid metabolism underlie a number of human diseases, including obesity, diabetes, and atherosclerosis.

Approximately half of the gene sequences of human and mouse genomes comes from so-called mobile elements—genes that jump around the genome. Much of this DNA is no longer capable of moving, but is likely “auditioning”  perhaps as a regulator of gene function or in homologous recombination, which is a type of genetic recombination where the basic structural units of DNA,  nucleotide sequences, are exchanged between two DNA molecules to  repair  breaks in the DNA  strands. Modern mammalian genomes also contain numerous intact movable elements, such as retrotransposon LINE-1, that use RNA intermediates to spread about the genome.

Globular clusters are spherical systems of some 100,000  gravitationally bound stars. They are among the oldest components of our galaxy and are key to understanding the age and scale of the universe. Previous measurements of their distances have compared the characteristics of different types of stars in the solar neighborhood with the same types of stars found in the clusters. However, these measurements have systematic errors, which limit the determination of cluster ages and distances.

 Ian Thompson has a different approach to the problem: using observations of exceedingly rare Detached Eclipsing Binary stars. These systems have two separated stars orbiting each

Alycia Weinberger wants to understand how planets form, so she observes young stars in our galaxy and their disks, from which planets are born. She also looks for and studies planetary systems.

Studying disks surrounding nearby stars help us determine the necessary conditions for planet formation. Young disks contain the raw materials for building planets and the ultimate architecture of planetary systems depends on how these raw materials are distributed, what the balance of different elements and ices is within the gas and dust, and how fast the disks dissipate.

Weinberger uses a variety of observational techniques and facilities, particularly ultra-high spatial-

Alan Linde is trying to understand the tectonic activity that is associated with earthquakes and volcanos, with the hope of helping predictions methods.  He uses highly sensitive data that measures how the Earth is changing below the surface with devises called borehole strainmeters that measure tiny strains the Earth undergoes.

Strainmeter data has led to the discovery of events referred to as slow earthquakes that are similar to regular earthquakes except that the fault motions take place over much longer time scales. These were first detected in south-east Japan and have since been seen in a number of different environments including the San Andreas Fault in California and

Dave Mao, now retired, has focused on ultra-high pressure physics, chemistry, material sciences, geophysics, geochemistry and planetary sciences using diamond-anvil cell techniques that he has pioneered.

Mao pioneered the diamond anvil cell, an instrument designed to subject materials to high pressures and temperatures by squeezing matter between two diamond tips. Over the years Mao has improved on both the diamond anvil cell and measurement instrumentation that reveals the properties of materials as they undergo extreme conditions. He has made many important discoveries about the chemical, structural, and other physical characteristics of matter along the way.
