ESA Mars Science Conference NatureFrozen sea discovered near Martian equator from 3D images of Mars Express
The discovery, by an international team of scientists led by University College London (UCL), the Open University (OU), and the Free University of Berlin, of a frozen sea close to the equator of Mars has brought the possibility of finding life on Mars one step closer.

PLOS BiologyThe secret to longevity in tubeworms
In a study published in the freely-available online science journal PLoS Biology, modeling the interactions between deep-sea tubeworms and bacteria/archaea at hydrocarbon seeps provides a solution to their long term energy source and could help to explain the tubeworm's extreme longevity.

PLOS BiologyCracking the olfactory code in bees
In the premier open-access journal PLoS Biology, a study shows that training thousands of bees uncovers the chemical characteristics they use to discriminate between odors and reveals how the perception of odor correlates with specific neural activity in their brain.

Journal of Experimental MedicineInflammatory molecules released by pollen trigger allergies
How do pollen particles provoke allergic reactions? A new study in the February 21 issue of The Journal of Experimental Medicine puts some of the blame on bioactive molecules that are released from pollen. These molecules bind to immune cells and cause them to launch a typical allergy-promoting immune response.

AAAS 2005 Annual MeetingSecrets of whales' long-distance songs are being unveiled
Christopher Clark, director of Cornell University's Bioacoustics Research Program, listens to whales in the Atlantic using the U.S. Navy's SOSUS. From acoustical maps, Clark realizes whales have a different time scale. He discussed this at the 2005 annual AAAS meeting in Washington, D.C.

AAAS 2005 Annual MeetingAstronomers measure mass of smallest black hole in a galactic nucleus
A group led by astronomers from Ohio State University and the Technion-Israel Institute of Technology have measured the mass of a unique black hole, and determined that it is the smallest found so far. Early results indicate that the black hole weighs in at less than a million times the mass of our sun -– which would make it as much as 100 times smaller than others of its type.

AAAS 2005 Annual MeetingThe secret lives of whales
Using genetics, Navy sonar, deep-sea submersibles, and toxicology, scientists are peering into the lives of whales – past and present – in ways never before possible. At a 3:00 PM press conference on February 19th at the annual meeting of AAAS, leading researchers will share their latest discoveries emerging from these high tech ventures, using DNA sequences, deep-sea video and sound-clips.

AAAS 2005 Annual MeetingWere bigger brains really smarter?
Bigger is smarter is better. That's the conventional wisdom for why the human brain gradually became three times larger than the ancestral brain. But bigger brains were not generally smarter brains. Archaeological records indicate our ancestors went through two periods of more than a million years each in which tool-making techniques didn't gradually improve, despite a gradual brain size increase.

AAAS 2005 Annual MeetingSmall is different
The practice of pairing computer simulations with real-world experiments is becoming more vital as scientists delve deeper into realms where the actors are measured on the nanoscale.

AAAS 2005 Annual MeetingBrain controls robot arm in monkey, University of Pittsburgh researcher reports at AAAS
Scientists have made significant strides to create a permanent artificial device that can restore deliberate mobility to patients with paralyzing injuries. The concept is that, through thought alone, a person could direct a robotic arm – a neural prosthesis – to reach and manipulate a desired object.
