With the help of modern technologies, scientists describe an exciting and long-overlooked new species of white toothed shrew, representing a rare new addition to the group of the mammals.

A potentially life-saving protein takes shape Posted: 02 Jul 2013 09:33 AM PDT The protein ubiquitin, found in all membranous cells, may hold the key to treating diseases from cancer to Parkinson's. Structural biologists examine an omnipresent but rarely studied form of ubiquitin, the polymeric ubiquitin chains linked by the animo acid Lysine-11. The team finds these chains are remarkably flexible and probably multi-functional.

Brown fat responsible for from heart disease-related deaths in cold winter months Posted: 02 Jul 2013 09:33 AM PDT More people die from heart-disease during the winter months, and according to a new study, the increase in mortality is possibly due to the accelerated growth of atherosclerotic plaque in the blood vessels caused by the activation of brown fat by the cold.

Listening to blood cells: Simple test could use sound waves for diagnosing blood-related diseases Posted: 02 Jul 2013 09:33 AM PDT New research reveals that when red blood cells are hit with laser light, they produce high frequency sound waves that contain a great deal of information. Similar to the way one can hear the voices of different people and identify who they are, investigators could analyze the sound waves produced by red blood cells and recognize their shape and size. The information may aid in the development of simple tests for blood-related diseases.

Names for new Pluto moons accepted Posted: 02 Jul 2013 09:31 AM PDT The International Astronomical Union has officially recognized the names Kerberos and Styx for the fourth and fifth moons of Pluto respectively (formerly known as P4 and P5).

People show more humorous creativity when primed with thoughts of death Posted: 02 Jul 2013 07:03 AM PDT Humor is an intrinsic part of human experience. It plays a role in every aspect of human existence, from day-to-day conversation to television shows. Yet little research has been conducted to date on the psychological function of humor. In human psychology, awareness of the impermanence of life is just as prevalent as humor. According to the Terror Management Theory, knowledge of one's own impermanence creates potentially disruptive existential anxiety, which the individual brings under control with two coping mechanisms, or anxiety buffers: rigid adherence to dominant cultural values, and self-esteem bolstering.

The ribosome: New target for antiprion medicines Posted: 02 Jul 2013 07:01 AM PDT The key to treating neurodegenerative prion diseases such as mad cow disease and Creutzfeldt-Jakob disease may lie in the ribosome, the protein synthesis machinery of the cell.

Fishing in the sea of proteins: Composition of splicing complex in chloroplasts identified for the first time Posted: 02 Jul 2013 07:01 AM PDT To convert a gene into a protein, a cell first crafts a blueprint out of RNA. One of the main players in this process has been identified by researchers. The team "fished" a large complex of proteins and RNA, which is involved in the so-called splicing, from the chloroplasts of the green alga Chlamydomonas reinhardtii. This cuts non-coding regions out of the messenger RNA, which contains the protein blueprint.

Cluster spacecraft detects elusive space wind Posted: 02 Jul 2013 07:01 AM PDT A new study provides the first conclusive proof of the existence of a space wind first proposed theoretically over 20 years ago. By analysing data from the European Space Agency's Cluster spacecraft, researchers detected this plasmaspheric wind, so-called because it contributes to the loss of material from the plasmasphere, a donut-shaped region extending above the Earth's atmosphere.

Scientists help explain visual system's remarkable ability to recognize complex objects Posted: 02 Jul 2013 07:00 AM PDT How is it possible for a human eye to figure out letters that are twisted and looped in crazy directions, like those in the little security test internet users are often given on websites? It seems easy to us -- the human brain just does it. But the apparent simplicity of this task is an illusion. The task is actually so complex, no one has been able to write computer code that translates these distorted letters the same way that neural networks can. That's why this test, called a CAPTCHA, is used to distinguish a human response from computer bots that try to steal sensitive information. Now, a team of neuroscientists has taken on the challenge of exploring how the brain accomplishes this remarkable task. Two studies demonstrate how complex a visual task decoding a CAPTCHA, or any image made of simple and intricate elements, actually is to the brain.
