New molecular tools are emerging to identify lung adenocarcinomas during pulmonary resection. The results of a proof-of-concept study suggest that lung cancer fluorescent imaging during surgery using targeted molecular agents may soon be a reality. While the methodology still needs refinement, the technique holds the possibility of precise visualization of tumor margins, detection of other tumors or metastases, localization of small malignant ground glass opacities, and accurate identification of lymph nodes containing metastatic cancer cells.
The merger of two black holes is one of the most sought-after observations of modern astronomy. The first observatories capable of directly detecting gravitational waves -- ripples in the fabric of spacetime predicted by Albert Einstein -- will begin observing the universe later this year. When these waves rolling in from space are detected on Earth for the first time, Northwestern University astrophysicists predict astronomers will 'hear,' through these waves, five times more colliding black holes than previously expected.
Rice is the staple food for more than half of the world's population, but the paddies it's grown in contributes up to 17 percent of global methane emissions -- about 100 million tons a year. Now, with the addition of a single gene, rice can be cultivated to emit virtually no methane, more starch for a richer food source and biomass for energy production, as announced in the July 30 edition of Nature and online.
Researchers mount successful attacks against popular anonymity network -- and show how to prevent them.
Images of an unusually dusty comet have revealed strange streaming clumps that could hold the secrets to how comets create their beautiful, sweeping, striated tails.
According to the Sandy Child and Family Health Study, a major report on NJ residents living in Superstorm Sandy's path, over 100,000 experienced significant structural damage to their primary homes. Conducted by Rutgers University, New York University, Columbia University and Colorado State University, research finds that tens of thousands still live with unfinished repairs, disputed claims and recurrent mold, all associated with increased odds of mental health distress, post-traumatic stress disorder, and depression.
Five years ago, the cost of rare-earth materials that are critical for today's electronics went through the roof. An export quota set by China, which mines most of the world's rare earths, caused the price run-up. Though short-lived, the occurrence spurred calls for developing mines outside China, but whether others can challenge the country's dominance remains to be seen, reports Chemical & Engineering News (C&EN), the weekly newsmagazine of the American Chemical Society.
The Alliance for Aging Research has released a new white paper discussing factors for underutilization of vaccines in older adults and offering recommendations to improve immunization rates.
Wine-making is steeped in age-old traditions, but to address the threat of pests and concerns over heavy pesticide use, vintners are turning to science. With the goal of designing better grape breeds, scientists are parsing the differences between wild American grapes -- which make terrible wine but are pest-resistant -- and the less hardy grape species pressed for fine wines worldwide. They report their findings in ACS' Journal of Agricultural and Food Chemistry.
Water uptake and fruit cracking in sweet cherries was observed following incubation in polyethylene glycol 6000, real sweet cherry juice extracted from the same batch of fruit, or in artificial juice. A dramatic increase in cracking was observed when sweet cherry fruit was in direct contact with the expressed juice of sweet cherries. The research clearly identified malic acid as the major crack-promoting component in sweet cherry juice.
