A. Paul Alivisatos, co-editor of Nano Letters, wins the Ernest Orlando Lawrence Award for his contributions to materials research and development of functional semiconducting nanocrystals, also known as quantum dots.
Researchers develop mechanism for capturing carbon dioxide from power plants and injecting it into the ground, where it will be trapped naturally. The injected gas forms a plume that rises through permeable rock, eventually breaking into small bubbles or blobs that remain safely stored.
Researchers at Yale University discovered a potential reversible cause of first-degree fetal heart block, which impairs the heart's electrical signaling. The PRIDE study found that early treatment with dexamethasone can reverse the condition, but it can progress rapidly to irreversible third-degree block.
A new study from Tufts University found that high folate status and adequate vitamin B12 levels are associated with better cognitive function in seniors. Low vitamin B12 status was linked to increased cognitive impairment, while high serum folate was more detrimental when combined with low vitamin B12.
Researchers at Tufts University have found that while older adults consume more vitamin K than younger adults, many still do not meet the recommended intake. High phylloquinone intake may be associated with better dietary habits and reduced risk of cardiovascular disease, but further research is needed.
Researchers at MIT envision a future where cellulosic ethanol becomes a significant part of the US energy supply due to its abundance and favorable energy balance. Current challenges include improving plant material production per acre and fermentation efficiency.
Researchers have discovered that all Type Ia supernovae explode with the same mass and energy, making them useful for measuring distances. The brightness of supernovae depends on the amount of nickel they contain, allowing for more accurate calibration and future distance measurements.
A Phase IV study found that Kadian's extended-release mechanism is maintained even in the presence of significant amounts of alcohol. The concomitant use of tested levels of alcohol with Kadian has no significant impact on morphine blood levels or release timing.
Researchers found African-American women are three times more likely to deliver prematurely and nearly five times more likely to experience recurrent preterm births. The study analyzed data from Missouri birth statistics between 1989 and 1997, adjusting for socioeconomic factors.
Researchers found that proteorhodopsin helps bacteria supplement energy when respiration is impaired. When exposed to light, these bacteria can use solar power to carry out vital life processes.
A new benchmark study finds that timeliness is a critical factor in the success of treatment for twin-twin transfusion syndrome (TTTS). The study, led by Dr. Timothy Crombleholme, highlights the importance of early diagnosis and aggressive intervention to improve survival rates. Fetal echocardiography is recommended as a crucial diagno...
Research shows African American mothers are 3 times more likely to deliver prematurely at 20-34 weeks and almost 4 times more likely to deliver extremely prematurely. Repeating premature births also occur at a significantly higher rate among African American women compared to Caucasian mothers.
Sequenom's Fetal Nucleic Acid Technology shows promise in detecting fetal DNA in maternal blood, potentially diagnosing genetic defects early in pregnancy. This approach could benefit all expectant mothers, particularly those with high-risk pregnancies.
Cold Spring Harbor Laboratory scientists have identified a new tumor suppressor gene, CHD5, which prevents multiple types of cancer. The gene's role in regulating the tumor-preventing power in cells suggests that modulation of its activity may provide novel strategies for better design of more effective cancer therapies.
Researchers found facial composite systems produce poor likenesses of the intended face, affecting accuracy in criminal identification. Whole-face methods show promise as a solution by utilizing holistic processing and multidimensional similarity, leading to improved results.
David Mendonça is leading a study on creativity by first responders after the 2001 World Trade Center attack and 1995 Oklahoma City bombing. The analysis draws from radio communications and interviews with response personnel.
Adolescents with parents in the military experience increased stress and physiological changes during wartime, including higher blood pressure and heart rates. Researchers found that these effects were particularly pronounced in children of deployed parents.
