Dr. Matthew P. Scott joins the Carnegie Institution for Science as its 10th president September 1, 2014. Scott was Professor of Developmental Biology, Genetics, Bioengineering, and Biology at the Stanford University School of Medicine. He spent nearly 24 years at Stanford. The Carnegie board of trustees announced his appointment in May.

Everyone’s heard of the birds and the bees. But that old expression leaves out the flowers that are being fertilized. The fertilization process for flowering plants is particularly complex and requires extensive communication between the male and female reproductive cells. New research from an international team reports discoveries in the chemical signaling process that guides flowering plant fertilization.

Wendy Freedman, the Crawford H. Greenewalt Director of the Carnegie Observatories and chair of the Giant Magellan Telescope Organization has accepted a position as a University Professor of Astronomy & Astrophysics at the University of Chicago, departing Carnegie September 1, 2014. Associate Director for Academic Affairs at the Observatories, John Mulchaey, will take over then as acting director.

Astronomers have discovered an extremely cool object that could have a particularly diverse history—although it is now as cool as a planet, it may have spent much of its youth as hot as a star. The current temperature of the object is intermediate between that of the Earth and of Venus. However, the object shows evidence implying that a potentially large change in temperature has taken place. In the past this object would have been as hot as a star for many millions of years.

Molybdenum disulfide is a compound often used in dry lubricants and in petroleum refining. Its semiconducting ability and similarity to the carbon-based graphene makes molybdenum disulfide of interest to scientists as a possible candidate for use in the manufacture of electronics, particularly photoelectronics. New work reveals that molybdenum disulfide becomes metallic under intense pressure.

Today a team, led by Greg Asner,  unveiled the first high-resolution map of the carbon stocks stored on land throughout the entire country of Perú. The new and improved methodology used to make the map marks a sea change for future market-based carbon economies. The new carbon map also reveals Perú’s extremely high ecological diversity and it provides the critical input to studies of deforestation and forest degradation for conservation, land use, and enforcement purposes.

Nobel laureate and trustee emeritus Charles Townes is celebrating his 99th birthday on Monday, July 28. Townes joined the Carnegie board in 1965, one year after he shared the Nobel Prize in Physics with Alexander Prokhorov and Nikolai Basov for the development of the maser, acronym for microwave amplification by stimulated emission of radiation, and its better-known optical counterpart, the laser.

The planet’s soil releases about 60 billion tons of carbon into the atmosphere each year, which is far more than that released by burning fossil fuels. This happens through a process called soil respiration. Short-term warming studies have documented that rising temperatures increase the rate of soil respiration. As a result, scientists have worried that global warming would accelerate the decomposition of carbon in the soil, and decrease the amount of carbon stored there. If true, this would release even more carbon dioxide into the atmosphere, where it would accelerate global warming.

Eating meat contributes to climate change, due to greenhouse gasses emitted by livestock. New research finds that livestock emissions are on the rise and that beef cattle are responsible for far more greenhouse gas emissions than other types of animals.
