Call it "PAC-MAN, the Sequel." Scientists with NASA's Cassini mission have spotted a second feature shaped like the 1980s video game icon in the Saturn system, this time on the moon Tethys. The pattern appears in thermal data obtained by Cassini's composite infrared spectrometer, with warmer areas making up the PAC-MAN shape. "Finding a second PAC-MAN in the Saturn system tells us that the processes creating these 'PAC-MEN' are more widespread than previously thought," said Dr. Carly Howett, the lead author of a recently published paper in the journal Icarus. "The Saturn ...

An international team of biologists led by Indiana University's David M. Kehoe has identified both the enzyme and molecular mechanism critical for controlling a chameleon-like process that allows one of the world's most abundant ocean phytoplankton, once known as blue-green algae, to maximize light harvesting for photosynthesis. Responsible for contributing about 20 percent of the total oxygen production on the planet, the cyanobacteria Synechococcus uses its own unique form of a sophisticated response called chromatic acclimation to fine tune the absorption properties ...

Implementation of the Affordable Care Act – now assured by the re-election of President Obama – is expected to result in up to 50 million currently uninsured Americans acquiring some type of health insurance coverage. But a study by researchers at the Mongan Institute for Health Policy at Massachusetts General Hospital (MGH) finds that a significant percentage of the primary care physicians most likely to care for newly insured patients may be not be accepting new patients. The investigators note that strategies designed to increase and support these "safety-net" physicians ...

Shedding light on the limits of life in extreme environments, scientists have discovered abundant and diverse metabolically active bacteria in the brine of an Antarctic lake sealed under more than 65 feet of ice. The finding, described in this week's issue of the Proceedings of the National Academy of Sciences, is surprising because previous studies indicate that the brine has been isolated from the surface environment -- and external sources of energy -- for at least 2,800 years, according to two of the report's authors, Peter Doran and Fabien Kenig, both professors ...

You could call this "Pac-Man, the Sequel." Scientists with NASA's Cassini mission have spotted a second feature shaped like the 1980s video game icon in the Saturn system, this time on the moon Tethys. (The first was found on Mimas in 2010). The pattern appears in thermal data obtained by Cassini's composite infrared spectrometer, with warmer areas making up the Pac-Man shape. "Finding a second Pac-Man in the Saturn system tells us that the processes creating these Pac-Men are more widespread than previously thought," said Carly Howett, the lead author of a paper recently ...

The twenty-sixth tropical cyclone of the western North Pacific Ocean season formed and has some areas of heavy rain, according to data from NASA's TRMM satellite. Tropical Depression 26W is threatening islands within Micronesia and warnings and watches are currently in effect. Micronesia is a region in the western North Pacific Ocean made up of thousands of small islands. West of the region is the Philippines, while Indonesia is located to the southwest. NASA's Tropical Rainfall Measuring Mission (TRMM) satellite passed over Tropical Depression 26W on Nov. 26 at 0526 ...

CHICAGO – The radiation dose to areas of the body near the breast during mammography is negligible, or very low, and does not result in an increased risk of cancer, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA). The results suggest that the use of thyroid shields during mammography is unnecessary. "Thyroid shields can impede good mammographic quality and, therefore, are not recommended during mammography," said Alison L. Chetlen, D.O., assistant professor of radiology at Penn State Hershey Medical Center. During ...

CHICAGO – Radiologists in Toronto have begun to identify a pattern of injuries that may be indicative of elder abuse, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA). According to lead researcher Kieran J. Murphy, M.D., F.R.C.P.C., F.S.I.R., interim radiologist-in-chief at University Health Network in Toronto, Canada, only 2 percent of physical elder abuse is reported by clinicians. "Unlike cases of child abuse, there is very little information available on this subject," Dr. Murphy said. "It's a much ...

CHICAGO – Researchers reviewing the records of approximately 250,000 women enrolled in an integrated healthcare delivery system found that increased CT utilization between 2000 and 2010 could result in an increase in the risk of breast cancer for certain women, including younger patients and those who received repeat exams. According to the study, which was presented today at the annual meeting of the Radiological Society of North America (RSNA), nuclear medicine examinations may also contribute to increased breast cancer risk. CT uses ionizing radiation in the form ...

CHICAGO – A survey of women undergoing routine screening mammography found that many of them would be interested in pursuing additional screening tests if notified they had dense breast tissue, despite the possibility of false positives, invasive procedures, and out-of-pocket costs, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA). "Our study highlights the need for patient education regarding breast density," said Jafi Lipson, M.D., assistant professor of radiology at Stanford University School of Medicine ...

CHICAGO – Researchers assessing the impact of revised guidelines for screening mammography issued by the U.S. Preventive Services Task Force (USPSTF) found evidence that the new recommendations may lead to missed cancers and a decline in screening, according to two studies presented today at the annual meeting of the Radiological Society of North America (RSNA). Routine screening mammography has traditionally been recommended by both the USPSTF and the American Cancer Society for all women over the age of 40. In 2009, the USPSTF issued controversial new guidelines recommending ...

CHICAGO – Chemotherapy can induce changes in the brain that may affect concentration and memory, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA). Using positron emission tomography combined with computed tomography (PET/CT), researchers were able to detect physiological evidence of chemo brain, a common side effect in patients undergoing chemotherapy for cancer treatment. "The chemo brain phenomenon is described as 'mental fog' and 'loss of coping skills' by patients who receive chemotherapy," said Rachel ...

The wetting model is a classical problem in surface science and biomimetic science. Professor LIU Jianlin and his collaborators from China University of Petroleum, Wuhan University and Fourth Military Medical University approached this old and classical problem from a new direction. They stressed that it is the triple contact line and not the contact area of the droplet/solid interface that determines the macroscopic contact angle. The proposed continuum model, termed the mechanism-based model, can illustrate the contact line pinning effect at some wedges or phase interfaces ...

New Johns Hopkins research showing a more than four-fold increase in the incidence of breast cancer in women with neurofibromatosis-1 (NF1) adds to growing evidence that women with this rare genetic disorder may benefit from early breast cancer screening with mammograms beginning at age 40, and manual breast exams as early as adolescence. In a small study of 126 women with NF1 at the Johns Hopkins Comprehensive Neurofibromatosis Center, the Johns Hopkins scientists identified four cases of breast cancer. The study showed a four-fold increased risk for breast cancer in ...

By using a model, researchers at the University of Montreal have identified and "switched off" a chemical chain that causes neurodegenerative diseases such as Huntington's disease, amyotrophic lateral sclerosis and dementia. The findings could one day be of particular therapeutic benefit to Huntington's disease patients. "We've identified a new way to protect neurons that express mutant huntingtin proteins," explained Dr. Alex Parker of the University of Montreal's Department of Pathology and Cell Biology and its affiliated CRCHUM Research Centre. A cardinal feature of ...

Bankruptcy Can Help New Jersey Homeowners Avoid Foreclosure New Jersey second quarter foreclosure statistics were recently released. At first glance, the results appear encouraging. The overall number of New Jersey foreclosure sales decreased from last year by 40 percent. During the second quarter, one out of 11 New Jersey home sales involved a foreclosed property, in contrast to one in four nationwide. However rosy the numbers look, experts say that the apparent statistical decrease in mortgage foreclosures is likely not due to a decrease in the actual number of ...

Michigan's "Super Drunk" Law: Higher BAC, More Penalties Many drivers convicted of driving while intoxicated have a high blood alcohol concentration. Even just a few drinks in an hour can put a driver over the legal limit to drive, which is .08 percent in all 50 states. However, a significant number of drunk driving convictions stem from incidents where a driver is more than twice the legal limit to drive. In an attempt to target such high BAC drivers, Michigan adopted a so-called "Super Drunk" law, which increases the fines and penalties associated ...

Spinal Cord Injury Research Continuing Spinal cord research has made strides in recent years, good news to the 5.6 million paralyzed people currently living in America and the 12,000 new people hospitalized for spinal cord injury (SCI) every year. However, progress is being made in fits and starts, and new research continues to battle this devastating injury. Promising New Research Neuroscience 2012, the annual meeting of the Society for Neuroscience, offered a variety of potential future solutions to SCI, from reducing pain in the injured patient to actually curing ...

New study shows bedsores linked to patient fatalities When we come to the conclusion that we must turn over the care of a loved one to a nursing home, it is common for that difficult decision to be accompanied by fears about his or her continued well-being. One of the dangers associated with nursing home care is the development of bedsores, also referred to as pressure ulcers. Recently, a new study revealed that the consequences of these injuries can be far more serious than previously understood. Bedsores occur when the tissue and skin on an individual are injured, ...
