A 20-year study reveals a significant rise in childhood obesity, especially among girls, with four-year-olds being six times more likely to have a BMI over 30 than their counterparts 20 years ago. Young girls are also more likely to be overweight or obese than boys, with nearly a third of ten-year-old girls having a BMI over 25.
Scientists have discovered that earthquake-induced gravity field changes can slowly recover to initial conditions, possibly due to simultaneous diffusion of mantle water. This self-healing system could significantly reduce permanent shifts in the Earth's rotation axis by earthquakes. Meanwhile, recent trends in Arctic Ocean mass distri...

Researchers at the University of Pennsylvania School of Medicine have found that natalizumab reduces both visual loss and disability in patients with relapsing multiple sclerosis. Vision loss is a common symptom of MS, and this study provides strong validation for a simple measure of visual function.
A recent study by Dr Yin Paradies and colleagues reveals that indigenous people do not have a genetic predisposition to diabetes. The research shows that social factors such as poor diet, reduced physical activity, stress, and low birth weight contribute significantly to the high rates of diabetes among indigenous populations.
The study analyzed existing genetic studies and found that non-genetic factors such as poverty, housing segregation, and poor diet are stronger indicators of diabetes than genes. The findings challenge the widely held thrifty genotype theory, which suggests that certain minority groups are genetically prone to diabetes.
A new study by NHLBI found that elevated risk factors in young adulthood significantly increase the risk of developing coronary calcium, a predictor of heart disease. Young adults with above-optimal levels of risk factors are two to three times more likely to develop coronary calcium than those with lower levels.
The Department of Energy has awarded $27.5 million for two field research studies to investigate contaminated groundwater at the Hanford Site in Washington and a uranium mill tailings site in Colorado. The studies aim to identify new approaches to resolve questions about subsurface contaminant movement.
The Gravity Probe B satellite has confirmed Einstein's predicted geodetic effect to a precision of better than 1 percent, but the frame-dragging effect is 170 times smaller and requires further analysis. Electrostatic patches on the gyroscopes' surface cause small torques, complicating the measurement of relativity effects.
A consortium of Canadian and American researchers have identified three major genetic risk factors for Crohn's disease: PHOX2B, NCF4, and ATG16L1. These findings highlight biological pathways not previously thought to play a role in the disease, including altered reactive oxygen species production and autophagic processes.
Researchers found that Hodgkin's disease survivors with higher chromosomal aberrations are two-and-a-half times more likely to develop another type of cancer. Chromosomal breaks, particularly those on one chromosome arm, may serve as a biomarker for predicting second primary tumor risk.
Researchers found that cetuximab improved overall survival by 23% and reduced disease progression risk by 32%. The drug targets the EGFR receptor on cancer cells, preventing cell growth and triggering an immune response.
