• 23:24 Bay Area thrushes nest together, winter together, and face change together

  Read the story at PhysOrg
  Swainson' s Thrushes, from a local population near Bolinas, CA spend their winters together in Mexico, according to a new tracking study released by Point Blue Conservation Science, (Point Blue, formerly PRBO). This result is important because it shows that the conservation of habitat for these local populations in California is tightly linked with climate and habitat changes in Mexico, where these birds spend their winters, 1,600 miles away.

• 23:24 New computer simulations help scientists understand how—and why—viruses spread

  Read the story at PhysOrg
  It's not a hacker lab. At Brandeis University, sophisticated computational models and advances in graphical processing units are helping scientists understand the complex interplay between genomic data, virus structure and the formation of the virus' outer "shell"—critical for replication.

• 23:24 The hidden agenda of Obama's opposition

  Read the story at PhysOrg
  Is the US Tea Party movement a racial backlash against President Obama? A new study by Angie Maxwell from the University of Arkansas, and Wayne Parent from Louisiana State University, assesses whether racial attitudes are contributing to Tea Party membership, and if so, the exact nature of this racial prejudice. Their work is published online in Springer's journal, Race and Social Problems.

• 23:24 Cassini imaging lead hopes for planet-wide celebration of the Pale Blue Dot

  Read the story at PhysOrg
  (Phys.org) —On July 19, 2013, NASA's Cassini spacecraft will be turned to image Saturn and its entire ring system during a total eclipse of the sun, as it has done twice before during its previous 9 years in orbit. But this time, the images that will be collected have been specifically designed for something very special. They will capture, in natural color, a glimpse of our own planet next to Saturn and its rings, during an event that will be the first time Earthlings know in advance their picture will be taken from a billion miles away.

• 21:25 3D printing tiny batteries

  Read the story at PhysOrg
  (Phys.org) —3D printing can now be used to print lithium-ion microbatteries the size of a grain of sand. The printed microbatteries could supply electricity to tiny devices in fields from medicine to communications, including many that have lingered on lab benches for lack of a battery small enough to fit the device, yet provide enough stored energy to power them.

  Read the story at PhysOrg
  (Phys.org) —A new study confirms directly what scientists previously knew only indirectly: The poisonous "rotten egg" gas hydrogen sulfide is generated by our body's growing cells. Hydrogen sulfide, or H2S, is normally toxic, but in small amounts it plays a role in cardiovascular health.

• 21:25 Long distance calls by sugar molecules

  Read the story at PhysOrg
  All our cells wear a coat of sugar molecules, so-called glycans. ETH Zurich and Empa researchers have now discovered that glycans rearrange water molecules over long distances. This may have an effect on how cells sense each other.

• 21:25 Shellfish show population growth did not send humans out of Africa

  Read the story at PhysOrg
  (Phys.org) —Artifacts from the Middle Stone Age, which lasted from about 200,000 to 50,000 years ago, provide us with the earliest glimpses of modern human art and culture. Previously, scientists thought an increase in population drove the behavioral innovations that led to the creation of these artifacts and eventually, the expansion out of Africa. However, by examining mollusk shells from Stone Age sites, Richard Klein of Stanford University and Teresa Steele of University of California, Davis, have determined that a significant population increase did not occur until the Late Stone Age, after the migration out of Africa had already begun. Their research appears in the Proceedings of the National Academy of Sciences.
