| Bat maps: The conservation crusade Posted: 02 Jul 2013 05:29 PM PDT Conservation efforts have taken an important step forward, thanks to observations of bats -- creatures that make up a quarter of all of the UK's native mammal species.  |
| Posted: 02 Jul 2013 05:29 PM PDT King penguin chicks survive harsh winters with almost no food by minimizing the cost of energy production. A new study shows that the efficiency of the mitochondria, the power house of the cell, is increased in fasted king penguin chicks.  |
| Posted: 02 Jul 2013 05:29 PM PDT If you rely on hand gestures to get your point across, you can thank fish for that! Scientists have found that the evolution of the control of speech and hand movements can be traced back to the same place in the brain, which could explain why we use hand gestures when we are speaking.  |
| Seeing cilia: Lighting the dark Posted: 02 Jul 2013 05:28 PM PDT Tagging a protein only found in cilia with a fluorescent protein (GFP) enables us to see the intricate working of cilia in live mice.  |
| Workers at industrial farms carry drug-resistant bacteria associated with livestock Posted: 02 Jul 2013 02:30 PM PDT A new study found drug-resistant bacteria associated with livestock in the noses of industrial livestock workers in North Carolina but not in the noses of antibiotic-free livestock workers. The drug-resistant bacteria examined were Staphylococcus aureus, commonly known as "Staph," which include the well-known bug MRSA (methicillin-resistant Staphylococcus aureus).  |
| Simple math may solve longstanding problem of parasite energetics Posted: 02 Jul 2013 12:10 PM PDT Feeling faint from the flu? Is your cold causing you to collapse? Your infection is the most likely cause, and, according to a new study, it may be possible to know just how much energy your bugs are taking from you.  |
| Invasive fly species continues to move northward Posted: 02 Jul 2013 12:10 PM PDT The local discovery of a species of fly not native to the Midwest could have significant implications on forensic investigations involving decomposing remains, according to a forensic biology researcher.  |
| Posted: 02 Jul 2013 11:15 AM PDT Climate change may be weeding out the bacteria that form the base of the ocean's food chain, selecting certain strains for survival, according to a new study.  |
| Molecular analysis reveals a new species of white toothed shrew Posted: 02 Jul 2013 09:33 AM PDT Judging solely by the looks proves to be a wrong practice in biology too. A recent study of the white toothed shrew fauna of Vietnam reveals the importance of molecular analysis for the correct recognition of species. 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.  |
| Posted: 02 Jul 2013 07:15 AM PDT Previously misunderstood multi-sensory organs in the skin of crocodylians are sensitive to touch, heat, cold, and the chemicals in their environment, new research finds. These sensors have no equivalent in any other vertebrate.  |
| Breakthrough: Sensors monitor cells at work Posted: 02 Jul 2013 07:08 AM PDT Transport proteins are responsible for moving materials such as nutrients and metabolic products through a cell's outer membrane, which seals and protects all living cells, to the cell's interior. A team has now developed a groundbreaking new way to measure the activity of transporter proteins in living organisms.  |
| Insecticide causes changes in honeybee genes, research finds Posted: 02 Jul 2013 07:06 AM PDT Exposure to a neonicotinoid insecticide causes changes to the genes of the honeybee.  |
| 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. Prion diseases are fatal neurodegenerative diseases caused by misfolding of prion proteins. Examples of prion diseases are scrapie in sheep, mad cow disease and Creutzfeldt-Jakob disease in human.  |
| Protocells may have formed in a salty soup Posted: 02 Jul 2013 07:01 AM PDT The first cell may have originated in a salty soup in which large biomolecules cluster spontaneously to form a protocell, chemists in the Netherlands have discovered.  |
| 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.  |
