Identifying the composition of the earth's core is key to understanding how our planet formed and the current behavior of its interior. While it has been known for many years that iron is the main element in the core, many questions have remained about just how iron behaves under the conditions found deep in the earth. Now, a team led by mineral-physics researchers at Caltech has honed in on those behaviors by conducting extremely high-pressure experiments on the element.

It was the brightest and closest stellar explosion seen from Earth in 25 years, dazzling professional and backyard astronomers alike. Now, thanks to this rare discovery—which some have called the "supernova of a generation"—astronomers have the most detailed picture yet of how this kind of explosion happens. Known as a Type Ia supernova, this type of blast is an essential tool that allows scientists to measure the expansion of the universe and understand the very nature of the cosmos.

Physicists have announced that the Large Hadron Collider (LHC) has produced yet more tantalizing hints for the existence of the Higgs boson. The European Center for Nuclear Research in Geneva, the international team of thousands of scientists—including many from Caltech—unveiled for the first time all the data taken over the last year from the two main detectors at the LHC, the Compact Muon Solenoid and ATLAS. The results represent the largest amount of data ever presented for the Higgs search.

Researchers have set a new world record for data transfer, helping to usher in the next generation of high-speed network technology. The international team was able to transfer data in opposite directions at a combined rate of 186 gigabits per second (Gbps) in a wide-area network circuit. The rate is equivalent to moving two million gigabytes per day, fast enough to transfer nearly 100,000 full Blu-ray disks—each with a complete movie and all the extras—in a day.

We've all heard that no two snowflakes are alike. Caltech professor of physics Kenneth Libbrecht will tell you that this has to do with the ever-changing conditions in the clouds where snow crystals form. Now Libbrecht, widely known as the snowflake guru, has shed some light on a grand puzzle in snowflake science: why the canonical, six-armed "stellar" snowflakes wind up so thin and flat.

The Voyager I spacecraft, which was built at JPL and launched in 1977, has reached a previously unexplored region between our solar system and interstellar space. Data collected from this zone indicates very little solar wind, a strong magnetic field, and a possible leak of high-energy particles from our solar system into the interstellar space. The latest findings from the mission were announced today at the American Geophysical Union's fall meeting in San Francisco.

Discoveries of new planets just keep coming and coming. A team of astronomers led by scientists at Caltech have found 18 Jupiter-like planets in orbit around massive stars.

Over the past year, researchers at Caltech, and around the world, have been studying a group of potent antibodies that have the ability to neutralize HIV in the lab; their hope is that they may learn how to create a vaccine that makes antibodies with similar properties. Now, biologists at Caltech led by Nobel Laureate David Baltimore have taken one step closer to that goal: they have developed a way to deliver these antibodies to mice and, in so doing, have effectively protected them from HIV infection.

Although many mental illnesses are uniquely human, animals sometimes exhibit abnormal behaviors similar to those seen in humans with psychological disorders. Such behaviors are called endophenotypes. Now, Caltech researchers have found that mice lacking a gene that encodes a particular protein found in the synapses of the brain display a number of endophenotypes associated with schizophrenia and autism spectrum disorders.
