AMHERST, Mass. – New fish-tagging studies of young bluefin tuna in Atlantic waters off New England by researchers at the University of Massachusetts Amherst are offering the first fishery-independent, year-round data on dispersal patterns and habitat use for the popular game fish. The availability of miniaturized pop-up satellite tags suitable for smaller (two- to five-year-old) fish helped make the research possible. Fisheries oceanographer Molly Lutcavage and lead author Benjamin Galuardi say the work shows that scientists now have tools to directly observe bluefin ...

This week's NEWSFOCUS section of the journal Science describes recent advances in sequencing technology. Stuart Lindsay, director of the Biodesign Institute's Center for Single Molecule Biophysics is on the forefront of this research, having successfully addressed a central stumbling block in nanopore sequencing—reading single nucleotide bases in a DNA chain. Lindsay's latest experimental ...

PORTLAND, Ore. — Women who are unable to quit smoking during pregnancy can significantly improve the lung function of their newborns by taking Vitamin C daily, according to a new study at Oregon Health & Science University Doernbecher Children's Hospital. "Smoking during pregnancy is known to adversely affect the lung development of the developing baby, causing lifelong decreased lung function and an increased risk of asthma," said Cindy McEvoy, M.D., M.C.R., neonatologist and associate professor of pediatrics at OHSU Doernbecher Children's Hospital. "We found that babies ...

It's quite common for a female song sparrow to stray from her breeding partner and mate with the male next door, but a new study shows that sleeping around can be costly. The 20-year study, which is reported in The American Naturalist, found that offspring conceived outside sparrows' social pairs go on to have lower reproductive success than within-pair offspring. The findings throw a monkey wrench into theories about why ostensibly monogamous animals might be inclined to cheat. Most bird species display some form of monogamy. Bonded pairs stay together for a breeding ...

BLOOMINGTON, Ind. -- Two popular MTV programs about teenage pregnancy -- "16 and Pregnant" and "Teen Mom" -- were met with national debate. Critics said the shows glamorized teenage pregnancy, while supporters said they discouraged it. A new study by an Indiana University professor suggests they're both right. The study, which will appear in the journal Sexuality & Culture, focused on female students because of the high dropout rate associated with pregnancy among this demographic. When the programs were under development, MTV sought the consultation of The National ...

CAMBRIDGE, Mass. -- A new study by civil engineers at MIT shows that using stiffer pavements on the nation's roads could reduce vehicle fuel consumption by as much as 3 percent — a savings that could add up to 273 million barrels of crude oil per year, or $15.6 billion at today's oil prices. This would result in an accompanying annual decrease in CO2 emissions of 46.5 million metric tons. The study, released in a recent peer-reviewed report, is the first to use mathematical modeling rather than roadway experiments to look at the effect of pavement deflection on vehicle ...

Richmond, Va. – (May 22, 2012) – Scientists at Virginia Commonwealth University Massey Cancer Center may be one step closer to developing a new therapy for acute myeloid leukemia (AML) after discovering that the targeted agents obatoclax and sorafenib kill leukemia cells much more effectively when combined than when the drugs are administered individually. Recently published in the journal Blood, the results of a study led by Steven Grant, M.D., Shirley Carter Olsson and Sture Gordon Olsson Chair in Oncology Research, associate director for translational research and program ...

NEW YORK (May 22, 2012) -- Up to half of all prostate cancer cells have a chromosomal rearrangement that results in a new "fusion" gene and formation of its unique protein -- but no one has known how that alteration promotes cancer growth. Now, Weill Cornell Medical College researchers have found that in these cancer cells, the 3-D architecture of DNA, wrapped up in a little ball known as a chromatin, is warped in such a way that a switch has been thrown on thousands of genes, turning them on or off to promote abnormal, unchecked growth. Researchers also found that new ...

CAMBRIDGE, Mass. (May 22, 2012) – Pushed to the brink of survival, the hyper-driven cells of a cancerous tumor tap into an ancient system that has helped organisms cope with internal stresses and environmental challenges since life began. As an integral part of this system, heat shock protein 90 (HSP90) has been shown to help malignant cells accommodate the genetic changes and profound disturbances in normal biology that occur in cancers. Researchers have theorized that inhibiting HSP90 just might render breast cancer cells less likely to escape the challenge posed ...

LEXINGTON, KY. (May 21, 2012) — A new study led by University of Kentucky researchers shows a new way to precisely detect a single chemical at extremely low concentrations and high contamination. The study, published online for ACS Nano, was carried out in the laboratory of Peixuan Guo, the William S. Farish Endowed Chair in Nanobiotechnology at the University of Kentucky Markey Cancer Center. The study shows that the phi29 DNA packaging nanomotor connector can be used to sense chemicals with reactive thioesters or maleimide using single channel conduction assays based ...

The universe is a marvelously complex place, filled with galaxies and larger-scale structures that have evolved over its 13.7-billion-year history. Those began as small perturbations of matter that grew over time, like ripples in a pond, as the universe expanded. By observing the large-scale cosmic wrinkles now, we can learn about the initial conditions of the universe. But is now really the best time to look, or would we get better information billions of years into the future - or the past? New calculations by Harvard theorist Avi Loeb show that the ideal time to study ...

WASHINGTON— The uproar that began last year when the U.S. Preventive Services Task Force stated that doctors should no longer offer regular prostate-cancer tests to healthy men continued this week when the task force released their final report. Overall, they stuck to their guns, stating that a blood test commonly used to screen for prostate cancer, the PSA test, causes more harm than good — it leads men to receive unnecessary, and sometimes even dangerous, treatments. But many people simply don't believe that the test is ineffective. Even faced with overwhelming evidence, ...

A special feature in this week's issue of the journal Science highlights protein array technology, touching on research conducted by Joshua LaBaer, director of the Biodesign Institute's Virginia G. Piper Center for Personalized Diagnostics. With the successful completion of the Human Genome Project, research attention is increasingly focusing on proteins. Versatile products produced from genetic templates, proteins are principle actors in both the maintenance of health and the onset of illness. Protein microarrays are a means of bridging the gap between analysis of the ...

On May 21, NASA satellites were monitoring Tropical Depression 02E in the eastern Pacific Ocean, and 24 hours later it strengthened into the second tropical storm of the season. Tropical Storm Bud was captured by NOAA's GOES-13 satellite on May 22, and appears to be well-formed. Tropical Storm Bud isn't going to stop there, however. According to the forecasters at the National Hurricane Center, Bud is expected to become a hurricane because of light to moderate wind shear and warm sea surface temperatures. On May 22 at 0900 UTC (2 a.m. PDT/5 a.m. EDT), Tropical Storm ...

Tropical Depression 03W in the western North Pacific did exactly what forecasters expected over the last twenty-four hours: it became a tropical storm named Sanvu and passed west of Guam on a northwesterly track. On May 22 at 0900 UTC (5 a.m. EDT), Tropical Storm Sanvu was more than 100 miles west-northwest of Andersen Air Force Base, Guam, and still over 600 nautical miles south of Iwo To, Japan and headed in that direction. Sanvu's center was located near 15.2 North and 141.9. East. It was still churning up rough surf around Guam. Sanvu has maximum sustained winds near ...
