Earth Core is Melting and Freezing

New findings could help us understand how the inner and outer core react as a geodynamo which create magnetic field. Dr Jon Mound from University of Leeds says that it's still hard to tell the origin of magnetic field as we can't go collect sample so we have to rely on surface measurement and computer models to tell us what's happening in the core.

 

Artificial Tissue Develop Skin Growth in Wounds

Victims of third-degree burns and other traumatic injuries endure pain, disfigurement, invasive surgeries and a long time waiting for skin to grow back. Improved tissue grafts designed by Cornell scientists that promote vascular growth could hasten healing, encourage healthy skin to invade the wounded area and reduce the need for surgeries.

Japan Quake May Have Slightly Shortened Earth Days, Moved Axis, Theoretical Calculations Suggest

The magnitude 9.0 earthquake that struck Japan March 11, 2011 may have slightly shortened the length of each Earth day and shifted its axis.

Why Low Birth Weight Is Linked to Obesity Later in Life: Study Provides Explanation

Providing further understanding of the link between low birth weights and obesity later in life, researchers found nutritionally deprived newborns are "programmed" to eat more because they develop less neurons in the region of the brain that controls food intake, according to an article published in the journal Brain Research.

Is South Pole Ice Melting? Gravity Field Satellites Observe Antarctic Ice Mass Fluctuations Due to El Niño

The change in the ice mass covering Antarctica is a critical factor in global climate events. Scientists at the GFZ German Research Centre for Geosciences have now found that the year by year mass variations in the western Antarctic are mainly attributable to fluctuations in precipitation, which are controlled significantly by the climate phenomenon El Niño. They examined the GFZ data of the German-American satellite mission GRACE (Gravity Recovery and Climate Experiment). The investigation showed significant regional differences in the western coastal area of the South Pole area.

Human Ancestors Lived on Shaky Ground

Our earliest ancestors preferred to settle in locations that have something in common with cities such as San Francisco, Naples and Istanbul -- they are often on active tectonic faults in areas that have an earthquake risk or volcanoes, or both.

Arctic Blooms Occurring Earlier: Phytoplankton Peak Arising 50 Days Early, With Unknown Impacts on Marine Food Chain and Carbon Cycling

Phytoplankton peak arising up to 50 days early, with unknown impacts on marine food chain and carbon cycling

Mapping Human Vulnerability to Climate Change

Researchers already study how various species of plants and animals migrate in response to climate change. Now, Jason Samson, a PhD candidate in McGill University's Department of Natural Resource Sciences, has taken the innovative step of using the same analytic tools to measure the impact of climate change on human populations. Samson and fellow researchers combined climate change data with censuses covering close to 97 per-cent of the world's population in order to forecast potential changes in local populations for 2050.

New Method for Accurate Diagnosis of Gall Bladder Cancer

Researchers a the University of Granada and the Department of Nuclear Medicine, Hospital Virgen de las Nieves at Granada found that the metabolic imaging diagnosis technique -- based on the analysis of a structural analog of glucose labeled with a positron-emitting compound (18F) -- allows early diagnosis of gall bladder cancer, a relatively rare disease with high mortality rates among most patients suffering from it.

Diet soda may be tied to heightened risk of stroke, study claims

DIET soda drinkers are probably doing their waistlines a favor, but may also be boosting their risk of having a stroke, according to research released by researchers from the University of Miami Miller School of Medicine.

Mobile phones may help reverse Alzheimer's disease

DESPITE the debate that radiation from mobile phones can cause brain cancer a new study has found a possible health benefit – that the electromagnetic waves may protect against and even reverse Alzheimer's disease.

Researchers Assess Severity of Prostate Cancers Using Magnetic Resonance Imaging

Rutgers researchers are developing methods that can accurately assess the severity of prostate cancer by analyzing magnetic resonance images and spectra of a patient's prostate gland. This may help physicians decide more confidently which patients need aggressive treatment and which are better served by "watchful waiting," and could even postpone or eliminate invasive biopsies in patients with low-grade tumors.

Headgear, Mouth Guards Have Little or No Impact on Reducing Concussions in Rugby Players, Study Finds

Existing headgear and mouth guards have limited or no benefit in reducing concussions in rugby players, according to Dr. Michael Cusimano, a neurosurgeon at St. Michael's Hospital.

Virus-Mimicking Nanoparticles Can Stimulate Long-Lasting Immunity

Vaccine scientists say their "Holy Grail" is to stimulate immunity that lasts for a lifetime. Live viral vaccines such as the smallpox or yellow fever vaccines provide immune protection that lasts several decades, but despite their success, scientists have remained in the dark as to how they induce such long lasting immunity.

Pomegranate Juice Components Could Stop Cancer from Spreading, Research Suggests

Researchers at the University of California, Riverside have identified components in pomegranate juice that both inhibit the movement of cancer cells and weaken their attraction to a chemical signal that promotes the metastasis of prostate cancer to the bone. The research could lead to new therapies for preventing cancer metastasis.

Spinal Cord Injury: Human Cells Derived from Stem Cells Restore Movement in Animal Models

For the first time, scientists discovered that a specific type of human cell, generated from stem cells and transplanted into spinal cord injured rats, provide tremendous benefit, not only repairing damage to the nervous system but helping the animals regain locomotor function as well.
