Many who await dentist appointments with a feeling of trepidation may do so with good reason. A study published yesterday in American Cancer Society found frequent dental X-rays may be linked to meningioma, an often benign but sometimes harmful brain tumor.

Noncommunicable diseases, from cancer and lung disease to cardiovascular disease and diabetes, cause almost two-thirds of global deaths. This figure reflects high levels of alcohol consumption, tobacco use and sugar intake. While alcohol and tobacco consumption is regulated, the regulation of sugar intake remains a topic of debate.

The University's Medical Center is a vital regional institution, but it also reaches out beyond the United States through its International Family Medicine Clinic. Medical School Prof. Dr. Fern Hauck, who works in the Department of Family Medicine, founded the clinic in October 2002, and it now treats refugees and immigrants from Somalia, Liberia, Burma, Iraq, and Central and South America. The clinic sees patients coming through the International Rescue Committee, where patients are screened for infectious diseases, and those who have received clearance from the Charlottesville Health Department.

A recent study conducted by the Institute of Cancer Epidemiology in Denmark shows no link between cell phone use and brain tumors. The study followed 350,000 people with cell phones during an 18-year period from 1982 to 1995 with a follow-up in 1996 and again in 2002 to reach its conclusions. Many scientists in the U.K., U.S., Austria, Sweden and Australia, however, characterize the methodology for the latest results this year as "seriously flawed."

The European Space Agency launched two Galileo satellites by a Russian Soyuz rocket from its French Guiana base. To compete with the American Global Positioning System, the European Commission has invested about $9.6 billion to provide Europeans with an alternative service, which will be free initially before transitioning to a paid service in 2020. The launch was delayed because of budget overruns, but officials are optimistic that the benefits of its precision will outweigh issues caused by its overspending. Officials estimate that Galilieo will bring in

Scientists' ability to observe the universe improved recently as the Atacama Large Millimeter/Submillimeter Array, a planned group of 66 antennas which simulates one large telescope, began operation Sept. 30. Europe, North America and East Asia are collaborating with the Republic of Chile in their investigation of star and galaxy formation through the telescope. Sixteen of the planned antennas have been installed thus far.

Research from psychologists at Pennsylvania State University suggests that sex hormones impact what profession an individual will likely choose as a career. The research focuses on a binary set of options given to teenagers and young adults: thing-oriented professions versus people-oriented professions. Thing-oriented professions include science, technology, engineering and mathematics fields, commonly known as STEM careers.

The U.K. National Physical Laboratory's atomic clock has become nearly twice as accurate as before because of a better understanding of wave frequencies and the disturbances which cause those frequencies to shift. The clock loses or gains less than a second in 138 million years, which makes this clock the "standard second" that keeps the time for global communications, satellite navigation and surveying and time stamping for financial markets.

Mosquitoes carrying malaria have almost disappeared in regions of sub-Saharan Africa, and data from Tanzania, Eritrea, Rwanada, Kenya and Zambia all suggest that the incidence of malaria is dropping quickly, Danish scientists reported in an article for Malaria Journal. The researchers are unsure of the causes of this situation, which some speculate could be because of the implementation of anti-mosquito bed nets and other control programs. In 2004, scientists caught 5,000 of the genus Anglopheles, a parasite mosquito which carries malaria, but in 2009, only 14 were caught in 2,368 traps. This data was obtained in a village which did not have any control programs or nets, however. Another hypothesis is that chaotic patterns of rainfall may have disturbed the natural cycle of mosquitoes, as occurred in the 1990s. Dan Meyrowitsch, associate professor at the University of Copenhagen's Institute for Public Health, said another cause may be a disease between the mosquitoes, such as a fungis or virus.

A hypothetical situation: You have been diagnosed with a rare disease. You have told your family and friends, garnering support for the future. What should your next move be? Share it on Facebook.\nMany people now explore the resources of the Internet to find useful information pertaining to rare and atypical conditions. A recent National Public Radio article analyzed the roles of Facebook and Twitter in the lives of people with lymphangioleiomyomatosis (LAM). LAM is a disease which slowly replaces healthy lung tissue with smooth muscle cells, making it harder and harder to breathe. It is usually diagnosed in young women, and some rely on lung transplants just to stay alive.

Out of 109 children who suffer from migraines with aura, 50 percent also were diagnosed with the congenital heart defect patent foramen ovale. More commonly known as a hole-in-the-heart, this defect consists of a hole formed in the wall between the heart's two upper chambers which can allow unfiltered blood to bypass the lungs and then circulate through the body. The rate of PFO in those who experience migraines with aura was nearly double the rate in the general population. The result of this finding leads many to believe that migraines can be cured with surgery, such as a catheter device.

Scientists say comets have caused the strange ripples observed in the ring systems of Saturn and Jupiter. The ripples in Jupiter's rings are believed to have been caused by the comet Shoemaker-Levy 9, which struck the planet in 1994. The findings suggest that the subtle corrugations seen in Saturn's rings, as well as the ripples detected in Jupiter's rings, can provide a record of the directions of comets, coming and going, after the time of impact of the atmosphere.
