High blood pressure during pregnancy could elevate risk of future stroke Posted: 18 Oct 2013 05:45 AM PDT High blood pressure during pregnancy could dramatically raise a woman's lifetime risk of stroke, according to a study.

Overnight dialysis boosts kidney health, reduces risk of heart disease Posted: 18 Oct 2013 05:45 AM PDT Receiving dialysis at home while sleeping not only improves kidney health and quality of life for people with kidney disease, it could also decrease their risk of heart disease.

Tiny 'LEGO brick' -style studs make solar panels a quarter more efficient Posted: 18 Oct 2013 05:44 AM PDT Most solar cells are made using thick layers of material to absorb sunlight, but have been limited in the past by relatively high costs. Many new, lower cost designs are limited as their layer of light-absorbing material is too thin to extract enough energy. In new research, scientists have demonstrated that the efficiency of all solar panel designs could be improved by up to 22 per cent by covering their surface with aluminium studs that bend and trap light inside the absorbing layer.

Scientists discover genetic disease that causes recurrent respiratory infections Posted: 17 Oct 2013 11:45 AM PDT Scientists have discovered a rare genetic disease that predisposes patients to severe respiratory infections and lung damage.

Scientists estimate 16,000 tree species in the Amazon Posted: 17 Oct 2013 11:45 AM PDT Researchers, taxonomists, and students from The Field Museum and 88 other institutions around the world have provided new answers to two simple but long-standing questions about Amazonian diversity: How many trees are there in the Amazon, and how many tree species occur there?

Web-based map allows users to see intricate patterns in U.S. Population Posted: 17 Oct 2013 11:44 AM PDT A new web-based mapping site allows users to see stark racial boundaries, subtle shifts in income, and intricate patterns of race, age, household size and income for any location in the United States

Bats discover surround sound Posted: 17 Oct 2013 11:44 AM PDT A new study by researchers shows that the furled leaves of Heliconia and Calathea plants where Spix's disc-winged bats make their home actually help to amplify and transmit the social calls of the bats.

World's first mapping of America's rare plants Posted: 17 Oct 2013 08:14 AM PDT The results of a major international research project show that climate stability plays a crucial role in the distribution of plants on Earth. Rare species in the Americas are restricted to areas of California, Mexico, the Caribbean islands, parts of the Andes mountains, the south of South America, and the region around Rio de Janeiro. The flora in most of North America and the Amazon basin, however, are dominated by widespread species.

3D images from PET/CT scans help surgeons envision tumors Posted: 17 Oct 2013 08:11 AM PDT A hologram-like display of a patient's organs based on molecular PET/CT images helps surgeons plan surgery by allowing them to see detailed anatomical structure, peel away layers of tissue, and see all sides of a tumor, before entering the operating room to excise it.

Toxin-emitting bacteria being evaluated as potential multiple sclerosis trigger Posted: 17 Oct 2013 06:38 AM PDT A research team has identified a bacterium it believes may trigger multiple sclerosis, a chronic, debilitating disorder that damages myelin forming cells in the brain and spinal cord.

Vertebral augmentation for spinal fractures offers greater survival, overall cost savings Posted: 17 Oct 2013 06:38 AM PDT A study of 69,000 Medicare patient records shows that people with spine compression fractures who undergo operations to strengthen back bones with cement survive longer and have shorter overall hospital stays than those who stick with bed rest, pain control and physical therapy.

Unlocking a brighter future for locked-in syndrome Posted: 17 Oct 2013 05:07 AM PDT A team of researchers has found that stroke patients living with Locked-In Syndrome who cannot move, swallow or even breathe on their own, can regain a remarkable level of independence with technological help.

A mother's high cholesterol before pregnancy can be passed on to children Posted: 17 Oct 2013 05:07 AM PDT What leads to high cholesterol? Your genes and lifestyle factors may not explain it all. A study has connected some of the risk for high cholesterol in adults to their mother's cholesterol levels before she even became pregnant.

More US teens susceptible to HSV-1 infection, a cause of genital herpes Posted: 17 Oct 2013 05:06 AM PDT A new study suggests a growing number of US adolescents lack antibodies that may help protect them later in life against an increasingly important cause of genital herpes. The findings show that fewer of today's teens have been exposed in their childhood to herpes simplex virus type 1 (HSV-1), a common cause of cold sores, than US adolescents in previous years. Without these antibodies, today's teens may be more susceptible to genital infections also caused by the virus.

All probiotics are not the same in protecting preemies from common, life-threatening illness Posted: 17 Oct 2013 05:06 AM PDT Treating premature infants with probiotics, the dietary supplements containing live bacteria that many adults take to help maintain their natural intestinal balance, may be effective for preventing a common and life-threatening bowel disease among premature infants.

The NICU environment: Not all silence is golden Posted: 17 Oct 2013 05:06 AM PDT Medical technology has improved the survival rates of premature infants, but adverse developmental outcomes are a continuing problem. Researchers have turned their attention to the neonatal intensive care unit (NICU), where premature infants spend their first few weeks or months, for potential answers. In a new study, researchers studied the relationship between different room types in the NICU and the developmental outcomes of the children at 2 years of age.

Suffering from breast cancer increases the risk of another tumour by 39% Posted: 17 Oct 2013 05:02 AM PDT Women diagnosed with invasive breast cancer are 39% more likely to develop a second cancer in a different part of the body. Such is the conclusion of a recent study. The study suggests that this increased risk could be due to the similar risk factors involved in both cancers, or to the side effects of the treatment received by breast cancer patients.

Cancer cells' communication path blocked Posted: 17 Oct 2013 05:02 AM PDT Cancer researchers have discovered the path used by exosomes to enter cancer cells, where they stimulate malignant tumour development. They have also succeeded in blocking the uptake route in experimental model systems, preventing the exosomes from activating cancer cells.

Watching the heartbeat of molecules Posted: 17 Oct 2013 05:01 AM PDT A team of scientists now report on a new method of rapidly identifying different molecular species under a microscope. Their technique of coherent Raman spectro-imaging with two laser frequency combs takes a big step towards the holy grail of real-time label-free biomolecular imaging.
