Drought hormones measured
Floods and droughts are increasingly in the news, and climate experts say their frequency will only go up in the future. As such, it is crucial for scientists to learn more about how these extreme events affect plants in order to prepare for and combat the risks to food security that could result. New work from Carnegie will allow researchers, for the first time, to measure the levels of a plant hormone involved in responses to drought stress in individual plant cells in real time.

Closest Sun-like star may have planets
An international team of scientists, including Carnegie’s Paul Butler, has discovered that Tau Ceti, one of the closest and most Sun-like stars, may have five planets. At a distance of twelve light years and visible with a naked eye in the evening sky, Tau Ceti is the closest single star with the same spectral classification as our Sun. Its five planets are estimated to have masses between two and six times the mass of the Earth--making it the lowest-mass planetary system yet detected.

DTM’s Richard Carlson to Receive 2008 N. L. Bowen Award from AGU
Carnegie geochemist Richard Carlson will receive the 2008 Norman L. Bowen Award from the American Geophysical Union. Named in honor of pioneering experimental petrologist and long-time Geophysical Laboratory staff member Norman Bowen, the award is given annually for outstanding contributions to volcanology, geochemistry or petrology.

Roller Coaster Superconductivity Discovered
Superconductors are more efficient at carrying electricity than copper wires. But these materials have to be cooled below an extremely low, so-called transition temperature for electrical resistance to disappear. Researchers at the Carnegie’s Geophysical Laboratory, have unexpectedly found that the transition temperature can be induced under two different intense pressures in a three-layered bismuth oxide crystal. They believe this unusual two-step phenomena comes from competition of electronic behavior in different layers.

Forest Carbon Monitoring Breakthrough in Colombia
Using new techniques, Carnegie and Colombian scientists have developed ultra-high resolution maps of the carbon stocks locked in tropical vegetation for 40% of the Colombian Amazon, an area about four times the size of Switzerland. Until now, the inability to accurately quantify carbon stocks at high spatial resolution over large areas has hindered the United Nations’ Reducing Emissions from Deforestation and Forest Degradation (REDD+) program aimed at creating a financial value for storing carbon in tropical forests.

Scientists discover how cancer may take hold
A team, led by researchers at the Carnegie Institution, has found a key biochemical cycle that suppresses the immune response, thereby allowing cancer cells to multiply unabated. The research shows how the biomolecules responsible for healthy T-cells, the body’s first defenders against hostile invaders, are quashed, permitting the invading cancer to spread. The same cycle could also be involved in autoimmune diseases such as multiple sclerosis.

Reforestation’s Cooling Influence--A Result of Farmers' Past Choices
Decisions by farmers to plant on productive land with little snow enhances the potential for reforestation to counteract global warming, concludes new research from Carnegie’s Julia Pongratz and Ken Caldeira. Previous research has led scientists and politicians to believe that regrowing forests on Northern lands that were cleared in order to grow crops would not decrease global warming. But these studies did not consider the importance of the choices made by farmers in the historical past.

Reproductive tract secretions elicit ovulation
Eggs take a long time to produce in the ovary, and thus are one of a body’s precious resources. It has been theorized that the body has mechanisms to help the ovary ensure that ovulated eggs enter the reproductive tract at the right time in order to maximize the chance of successful fertilization. New research from Carnegie's Allan Spradling and Jianjun Sun has shed light on how successful ovulation and fertilization are brought about by studying these processes in fruit flies. They found that secretions from special glands within the fruit fly’s reproductive tract contribute to both ovulation and sperm function, and that this secretion is controlled by a specific hormone receptor gene, called Hr39. Their results suggest that Lrh-1, a mammalian receptor gene closely related to Hr39, also regulates ovulation by controlling reproductive tract secretions in mammals.

Probing hydrogen under extreme conditions
How hydrogen--the most abundant element in the cosmos--responds to extremes of pressure and temperature is one of the major challenges in modern physical science. Moreover, knowledge gleaned from experiments using hydrogen as a testing ground on the nature of chemical bonding can fundamentally expand our understanding of matter. New work from Carnegie scientists has enabled researchers to examine hydrogen under pressures never before possible.

Asteroid Found in Gravitational “Dead Zone”
There are places in space where the gravitational tug between a planet and the Sun balance out, allowing other smaller bodies to remain stable called Lagrangian points. So-called Trojan asteroids have been found in some of these stable spots near Jupiter and Neptune. Now Scott Sheppard at the Carnegie’s Department of Terrestrial Magnetism and Chad Trujillo have discovered the first Trojan asteroid in a difficult-to-detect stability region at Neptune—the Lagrangian L5 point.

Giant Magellan Telescope Looking Toward Construction
The international consortium of the Giant Magellan Telescope (GMT) project has passed two major reviews and is positioned to enter the construction phase. When completed, the 25-meter GMT will have more than six times the collecting area of the largest telescopes today and ten times the resolution of the Hubble Space Telescope.

Under pressure: germanium
Although its name may make many people think of flowers, the element germanium is part of a frequently studied group of elements, called IVa, which could have applications for next-generation computer architecture as well as implications for fundamental condensed matter physics. New research reveals details of the element’s transitions under pressure. Their results show extraordinary agreement with the predictions of modern condensed matter theory.
