| Posted: 06 Aug 2013 05:35 PM PDT The first report of probable person to person transmission of the new avian influenza A (H7N9) virus in Eastern China has been documented. The findings provide the strongest evidence yet of H7N9 transmission between humans, but the authors stress that its ability to transmit itself is "limited and non-sustainable." |
| Length of human pregnancies can vary naturally by as much as five weeks Posted: 06 Aug 2013 05:33 PM PDT The length of a human pregnancy can vary naturally by as much as five weeks, according to new research. |
| Brain molecule regulating human emotion, mood uncovered Posted: 06 Aug 2013 05:33 PM PDT Scientists have discovered an enzyme called Rines that regulates MAO-A, a major brain protein controlling emotion and mood. The enzyme is a potentially promising drug target for treating diseases associated with emotions such as depression. |
| Sleep deprivation linked to junk food cravings Posted: 06 Aug 2013 11:55 AM PDT A sleepless night makes us more likely to reach for doughnuts or pizza than for whole grains and leafy green vegetables, suggests a new study that examines the brain regions that control food choices. The findings shed new light on the link between poor sleep and obesity. |
| Why tumors become drug-resistant Posted: 06 Aug 2013 10:28 AM PDT New findings could lead to drugs that fight back when tumors don't respond to treatment. |
| Emotional behavior of adults could be triggered in the womb Posted: 06 Aug 2013 10:27 AM PDT Adults could be at greater risk of becoming anxious and vulnerable to poor mental health if they were deprived of certain hormones while developing in the womb according to new research. |
| New design may produce heartier, more effective salmonella-based vaccines Posted: 06 Aug 2013 08:12 AM PDT Through genetic manipulation, the species S. Typhi can be rendered harmless and used in vaccines in order to prevent, rather than cause illness. Scientists have described efforts to improve the effectiveness of a Recombinant Attenuated Salmonella Vaccine by modifying its ability to survive the hostile environment of the stomach. |
| From harmless colonizers to virulent pathogens: Microbiologists identify what triggers disease Posted: 06 Aug 2013 08:10 AM PDT The bacteria Streptococcus pneumoniae harmlessly colonizes the mucous linings of throats and noses in most people, only becoming virulent when they leave those comfortable surroundings. Now, researchers reveal how that happens. |
| Posted: 06 Aug 2013 06:18 AM PDT Biologists found timber rattlesnakes, which prey on mice and other small mammals, help check humans' exposure to the tick-borne Lyme disease. |
| Super sunscreen from fjord bacteria Posted: 06 Aug 2013 06:15 AM PDT A microorganism living in Trondheim Fjord will provide you with better protection against skin cancer and malignant melanomas. |
| Breakdown of fat 'on hold': Biochemists discover 'parking position' of fat-burning enzymes Posted: 06 Aug 2013 06:15 AM PDT Fat is a curse and a blessing at the same time. While we would rather not have any fat deposits on our body, especially in summer, accumulated fats in plants are desirable as they make them especially nutritious. Biologists have found that enzymes are "parked" under certain conditions and suspend the breakdown of fat. |
| Walking to work cuts risk of diabetes and high blood pressure Posted: 06 Aug 2013 06:15 AM PDT People who walk to work are around 40 per cent less likely to have diabetes as those who drive, according to a new study. |
