Earliest Animals Lived In A Lake Environment, Research Shows Posted: 28 Jul 2009 11:00 AM PDT Researchers studying ancient rock samples in South China has found that the first animal fossils in the paleontological record are preserved in ancient lake deposits, not marine sediments as commonly assumed. The research gives scientists a glimpse into where some of the early animals lived and what the environmental conditions were like for them -- important information for addressing the broader questions of how and why animals appeared when they did.

Intensive Glucose Control Halves Complications Of Longstanding Type 1 Diabetes Posted: 28 Jul 2009 11:00 AM PDT Near-normal control of glucose beginning as soon as possible after diagnosis would greatly improve the long-term prognosis of type 1 diabetes, concludes a new study, which updates information about the clinical course of type 1 diabetes.

Rethinking Brownian Motion With The 'Emperor's New Clothes' Posted: 28 Jul 2009 11:00 AM PDT In the classic fairy tale, "The Emperor's New Clothes," Hans Christian Andersen uses the eyes of a child to challenge conventional wisdom and help others to see more clearly. In similar fashion, researchers have now revealed the naked truth about a classic bell-shaped curve used to describe the motion of a liquid as it diffuses through another material.

Researchers Warn: 'Antivirals Might Be Wasted On The Elderly' Posted: 28 Jul 2009 11:00 AM PDT A model of influenza transmission and treatment suggests that, if the current swine flu pandemic behaves like the 1918 flu, antiviral treatment should be reserved for the young. Researchers found that, in this situation, providing the elderly with antiviral drugs would not significantly reduce mortality, and may lead to an increase in resistance.

Key To Designing Quantum Information Networks: Quantum Memory And Turbulence In Ultra-cold Atoms Posted: 28 Jul 2009 11:00 AM PDT Scientists have figured out a key step toward the design of quantum information networks. A quantum network – in which memory devices that store quantum states are interconnected with quantum information processing devices – is a prototype for designing a quantum internet.

Trade Liberalization Linked To Obesity In Central America Posted: 28 Jul 2009 11:00 AM PDT Since trade liberalization between Central and North America, imports and availability of processed, high-fat and high-sugar foods have increased dramatically. Researchers link this influx of American junk food to a "nutrition transition" in Central American countries, with a growing burden diet-related chronic disease.

'Brain-reading' Methods Developed Posted: 28 Jul 2009 08:00 AM PDT It is widely known that the brain perceives information before it reaches a person's awareness. But until now, there was little way to determine what specific mental tasks were taking place prior to the point of conscious awareness. That has now changed.

Nanodiamonds Deliver Insulin For Wound Healing Posted: 28 Jul 2009 08:00 AM PDT Using tiny nanodiamonds, researchers have demonstrated an innovative method for delivering and releasing insulin at a specific location over a period of time.

Genetic Testing May Be Valuable In Treating Colorectal Cancer Posted: 28 Jul 2009 08:00 AM PDT A new cost-effectiveness study has determined that so-called pretreatment pharmacogenetic testing is only beneficial if dose-reduced treatment is shown to be nearly as effective as the full dose. If the lower dose is as effective, the test could prevent many cases of severe neutropenia, an abnormally low count of an important type of white blood cells known as neutrophils. It would also mean better life expectancy and lower cost of care.

Sichuan Earthquake Destroyed Nearly A Quarter Of Panda Habitat Near Quake's Epicenter Posted: 28 Jul 2009 08:00 AM PDT When the magnitude 8 Sichuan earthquake struck southern China in May 2008, it left more than 69,000 people dead and 4.3 million homeless. Now ecologists have added to these losses an assessment of the earthquake's impact on biodiversity. Researchers show that more than 23 percent of the pandas' habitat in the study area was destroyed, and fragmentation of remaining habitat could hinder panda reproduction.

Personal Values Color Understanding Of Sentences Within Milliseconds Posted: 28 Jul 2009 08:00 AM PDT Moral-ethical and political beliefs color the way people read opinion questions. This 'coloring' process takes place well before people become aware of their answers to such questions. This phenomenon was recently discovered through brain measurements.

Major Arctic Sea-ice Formed Earlier Than Thought Posted: 28 Jul 2009 05:00 AM PDT Significant sea ice formation occurred in the Arctic earlier than previously thought in Earth's geological history. "The results are also especially exciting because they suggest that sea ice formed in the Arctic before it did in Antarctica, which goes against scientific expectation," says one of the scientific team members.

Key Event In Prostate Cancer Progression Discovered Posted: 28 Jul 2009 05:00 AM PDT Researchers have discovered how hormone-dependent prostate cancer advances to the incurable hormone-independent disease state. The study shows that in androgen-independent prostate cancer, androgen receptors are reprogrammed to regulate genes involved in a later phase of cell division. A small epigenetic change in a gene called UBE2C is responsible for this reprogramming. Increased expression of that gene correlated with progression to the hormone-independent phase.

121 Breeding Tigers Estimated To Be Found In Nepal Posted: 28 Jul 2009 05:00 AM PDT Biologists welcome the news of an estimated 121 breeding tigers in four protected areas in the Terai Arc Landscape of Nepal as announced by the government in Kathmandu, July 27, 2009.

The findings may lead to improve targeted therapy for lung cancer, including tumors resistant to targeted drugs such as gefitinib.

Tooth Gel: Healing Power Of Aloe Vera Proves Beneficial For Teeth And Gums, Too Posted: 28 Jul 2009 02:00 AM PDT Aloe vera tooth gel is intended, like toothpaste, to eliminate disease-causing bacteria in the mouth. The ability of aloe vera tooth gel to do that successfully has been a point of contention for some dental professionals. The study compared the germ-fighting ability of a gel to two commercially popular toothpastes and revealed that the tooth gel was just as effective -- in some cases more effective -- as the commercial brands at controlling cavity-causing organisms.

Surgery Remains An Option For Advanced Lung Cancer Posted: 28 Jul 2009 02:00 AM PDT Oncologists have debated whether patients with a certain type of advanced lung cancer would benefit from surgery. Now a major study has found that surgery can significantly prolong survival without progression of the cancer, but does not dramatically improve overall survival.

Charging Ahead: Revealing Secrets Of Electricity-producing Materials Posted: 28 Jul 2009 02:00 AM PDT Much like humans, materials are capable of some pretty remarkable things when placed under pressure. In fact, under the right conditions, materials can even produce electricity. Driven by the vision of our society one day being basically self-propelled, scientists have set out to both amplify and provoke that potential in materials known as piezoelectrics, which naturally produce electricity when literally subjected to strain.

Most Older Long-term Cancer Survivors Have Poor Health Habits Posted: 28 Jul 2009 02:00 AM PDT A new study finds that most older long-term cancer survivors who are interested in diet and exercise actually have poor health habits, and that those survivors who do exercise and watch their diet have improved physical health and quality of life.

Chimps, Like Humans, Focus On Faces Posted: 27 Jul 2009 11:00 PM PDT A chimp's attention is captured by faces more effectively than by bananas. A series of experiments suggests that the apes are wired to respond to faces in a similar manner to humans.

Anemia Increases Risk Of Death In The Very Elderly Posted: 27 Jul 2009 11:00 PM PDT Anemia in very elderly people aged 85 and older appears to be associated with an increased risk of death, according to a new study.

Stem-Destroying Insect May Help Conquer Climbing Fern Posted: 27 Jul 2009 11:00 PM PDT Throughout much of Florida's famed Everglades, an invasive, light-green vine called Old World climbing fern now cloaks the forest floor. Besides smothering shrubs and even small trees with its dense, spongy mats, the intrusive fern, known to scientists as Lygodium microphyllum, also forms soft, twining stems that climb tree trunks. Underneath this layer of living fern, dry, dead lygodium stems accumulate, boosting the wildfire hazard.
