New super-Earth detected within the habitable zone of a nearby cool star

An international team of scientists led by Carnegie’s Guillem Anglada-Escudé and Paul Butler has discovered a potentially habitable super-Earth orbiting a nearby star. The star is a member of a triple star system and has a different makeup than our Sun, being relatively lacking in metallic elements. This discovery demonstrates that habitable planets could form in a greater variety of environments than previously believed.

Geoengineering and global food supply

Carbon dioxide emissions from the burning of coal, oil, and gas have been increasing over the past decades, causing the Earth to get hotter and hotter. There are concerns that a continuation of these trends could have catastrophic effects, including crop failures in the heat-stressed tropics. This has led some to explore drastic ideas for combating global warming, including the idea of trying to counteract it by reflecting sunlight away from the Earth. However, it has been suggested that reflecting sunlight away from the Earth might itself threaten the food supply of billions of people. New research led by Carnegie’s Julia Pongratz examines the potential effects that geoengineering the climate could have on global food production and concludes that sunshade geoengineering would be more likely to improve rather than threaten food security.

Carnegie’s BioEYES Honored Twofold

Baltimore, MD—Carnegie’s educational outreach program, BioEYES, will be the recipient of the 2012 Viktor Hamburger Outstanding Educator Prize from the Society for Developmental Biology. BioEYES founders Steve Farber and Jamie Shuda (University of Pennsylvania), will accept the award at the upcoming annual meeting of the society in Montreal in July. BioEYES, with program manager Valerie Butler, is also currently featured in a video on the front page of the Baltimore City Schools' website.

Mirror Casting Event for the Giant Magellan Telescope

On January 14, 2012, the second 8.4-meter (27.6 ft) diameter mirror for the Giant Magellan Telescope (GMT) will be cast inside a rotating furnace at the University of Arizona’s Steward Observatory Mirror Lab (SOML) underneath the campus football stadium. The Mirror Lab will host a special event to highlight the milestone. Members of the media are invited to visit the Mirror Lab on Saturday morning, January 14, 2012, between 9:00 and 11:00 a.m. MST.

Could Siberian volcanism have caused the Earth’s largest extinction event?

Around 250 million years ago, at the end of the Permian geologic period, there was a mass extinction so severe that it remains the most traumatic known species die-off in Earth’s history. Although the cause of this event is a mystery, it has been speculated that the eruption of a large swath of volcanic rock in Russia called the Siberian Traps was a trigger for the extinction. New research from Carnegie’s Linda Elkins-Tanton and her co-authors offers insight into how this volcanism could have contributed to drastic deterioration in the global environment of the period

Sea Cucumbers: Dissolving coral reefs?

Coral reefs are extremely diverse ecosystems that support enormous biodiversity. But they are at risk. Carbon dioxide emissions are acidifying the ocean, threatening reefs and other marine organisms. New research led by Carnegie’s Kenneth Schneider analyzed the role of sea cucumbers in portions of the Great Barrier Reef and determined that their  dietary process of dissolving calcium carbonate (CaCO3) from the surrounding reef accounts for about half of at the total nighttime dissolution for the reef.

New tool offers unprecedented access for root studies

Plant roots are fascinating plant organs – they not only anchor the plant, but are also the world’s most efficient mining companies. Roots live in darkness and direct the activities of the other organs, as well as interact with the surrounding environment. Charles Darwin posited in The Power of Movement of Plants that the root system acts as a plant’s brain. Due to the difficulty of accessing root tissue in intact live plants, research of these hidden parts has always lagged behind research on the more visible parts of plants. But now: a new technology--developed jointly by Carnegie and Stanford University--could revolutionize root research.

A New Kind of Metal in the Deep Earth

The crushing pressures and intense temperatures in Earth’s deep interior squeeze atoms and electrons so closely together that they interact very differently. With depth materials change. New experiments and supercomputer computations discovered that iron oxide undergoes a new kind of transition under deep Earth conditions. Iron oxide, FeO, is a component of the second most abundant mineral at Earth’s lower mantle, ferropericlase. The finding could alter our understanding of deep Earth dynamics and the behavior of the protective magnetic field, which shields our planet from harmful cosmic rays.

Solving a supernova mystery

A team of scientists, including Carnegie’s Mansi M. Kasliwal, has observed the early stages of a Type Ia supernova that is only 21 million light years away from Earth--the closest of its kind discovered in 25 years. The Palomar Transient Factory team’s detection of a supernova less than half a day after it exploded will refine and challenge our understanding of these stellar phenomena.
