| Florida's reefs cannot endure a 'cold snap' Posted: 26 Aug 2011 04:20 PM PDT Florida's corals dropped in numbers due to unseasonably cold weather conditions in 2010. The chilly January temperatures caused the most catastrophic loss of corals within the Florida Reef Tract, which spans 160 miles (260 kilometers) from Miami to the Dry Tortugas and is the only living barrier reef in the continental U.S.  |
| Posted: 26 Aug 2011 10:40 AM PDT Most bacterial infections can be treated with antibiotics such as penicillin, discovered decades ago. However, such drugs are useless against viral infections, including influenza, the common cold, and deadly hemorrhagic fevers such as Ebola. Now, in a development that could transform how viral infections are treated, a team of researchers has designed a drug that can identify cells that have been infected by any type of virus, then kill those cells to terminate the infection.  |
| Hand-held unit to detect cancer in poorer countries Posted: 26 Aug 2011 08:20 AM PDT An engineering researcher and a global health expert are working on bringing a low-cost, hand-held device to nations with limited resources to help physicians detect and diagnose cancer.  |
| Sensor chip for monitoring tumors Posted: 26 Aug 2011 08:20 AM PDT A chip implant may soon be capable of monitoring tumors that are difficult to operate on or growing slowly. Medical engineers have developed an electronic sensor chip that can determine the oxygen content in a patient's tissue fluid. This data can then be wirelessly transmitted to the patient's doctor to support the choice of therapy. A drop in oxygen content in tissue surrounding a tumor indicates that the tumor might be growing faster and becoming aggressive.  |
| Adapting to climate change with floating houses? Posted: 26 Aug 2011 08:15 AM PDT Climate change is redefining the rules by which we live and at a pace we never expected. Because of rising sea level, several areas of the globe are in danger of vanishing from the map, disappearing under water. Society must adapt and maybe, one day, live in floating houses in floating cities.  |
| Risk measurement tool for heart attacks and strokes updated Posted: 26 Aug 2011 08:15 AM PDT The number of heart attack and stroke incidents in Europe is likely to reduce with the imminent launch of an update to the HeartScore® application. HeartScore® helps clinicians rapidly estimate the risk of cardiovascular disease (CVD) in individual patients using age, gender, basic health indicators, and lifestyle factors. The results from the model are then used to shape intervention and advice regimes aimed at lowering CVD risk. Following feedback, HeartScore® has been updated to incorporate a number of new features that will enhance its value as part of CVD prevention strategies.  |
| Possible biological control discovered for pathogen devastating amphibians Posted: 26 Aug 2011 08:13 AM PDT Zoologists have discovered that a freshwater species of zooplankton will eat a fungal pathogen which is devastating amphibian populations around the world. It could provide a desperately needed tool for biological control of this deadly fungus.  |
| Posted: 26 Aug 2011 08:12 AM PDT For the first time, scientists can see pathways to stop a deadly brain cancer in its tracks. Researchers have imaged individual cancer cells and the routes they travel as the tumor spreads.  |
| Posted: 26 Aug 2011 08:12 AM PDT Researchers from Denmark have examined a number of plants which are used for illegal abortions in Tanzania. Several of the plants can be used to stop lethal bleeding after birth.  |
| Single parents and gay couples face rental housing discrimination, Canadian study finds Posted: 26 Aug 2011 08:12 AM PDT A new study by researchers in Canada finds that single parents are approximately 15 per cent more likely to be rejected by landlords seeking renters, while male gay couples are nearly 25 per cent more likely to be rejected. The research is the largest investigation of housing discrimination towards single parents, and the first to the explore geographic variation in their discrimination.  |
| Atomic clock with the world's best long-term accuracy is revealed after evaluation Posted: 26 Aug 2011 05:55 AM PDT A clock in the UK is the most accurate long-term timekeeper in the world, reveals a new study.  |
| Molecular chaperones traffic signaling proteins between cells in plant stem-cell maintenance pathway Posted: 25 Aug 2011 11:16 AM PDT Plant biologists have discovered that proteins called chaperonins are an indispensable factor in making possible cell-to-cell trafficking of signals that maintain stem cells and enable plants to grow.  |
