Solar observatories face the prospect of being eclipsed

Motors whirred as a gleaming white dome slowly opened, allowing one of the premier solar telescopes in the world to track the magnetic fields and exploding flares of the sun. In a few hours, computers would translate that data into detailed video and pictures of the sun's turbulent surface.

3-D culture system for pancreatic cancer has potential to change therapeutic approaches

Pancreatic cancer is one of the most deadly forms of cancer, with only 6 percent of patients surviving five years after diagnosis. Today, Cold Spring Harbor Laboratory (CSHL) and The Lustgarten Foundation jointly announce the development of a new model system to grow both normal and cancerous pancreatic cells in the laboratory. Their work offers the potential to change the way pancreatic cancer research is done, allowing scientists to interrogate the pathways driving this devastating disease while searching for new drug targets.

Patient stem cells used to make dementia-in-a-dish; help identify new treatment strategy

Belgian researchers have identified a new strategy for treating an inherited form of dementia after attempting to turn stem cells derived from patients into the neurons most affected by the disease. In patient-derived stem cells carrying a mutation predisposing them to frontotemporal dementia, which accounts for about half of dementia cases before the age of 60, the scientists found a targetable defect that prevents normal neurodevelopment. These stem cells partially return to normal when the defect is corrected.

Little change seen in fast food portion size, product formulation between 1996 and 2013

Two new reports from researchers at the USDA Human Nutrition Research Center on Aging at Tufts University shows little change in fast food portion sizes and product formulation between 1996 and 2013. Led by Alice H. Lichtenstein, D.Sc., director of the Cardiovascular Nutrition Laboratory at the USDA HNRCA, the researchers analyzed the calorie, sodium, saturated fat and trans fat content of popular menu items served at three national fast-food chains between 1996 and 2013. They found that average calories, sodium, and saturated fat stayed relatively constant, albeit at high levels. The exception was a consistent decline in the trans fat of fries.

Australia bans commercial sunbeds over cancer fears

Most Australian states and territories are set to ban commercial sunbeds from Thursday, in a crackdown on artificial tanning in a country that has one of the highest rates of skin cancer in the world.

Poll: Americans support menu labeling

Most Americans favor labeling calories on menus in fast food and sit-down restaurants. That's according to an Associated Press-GfK poll conducted in December that found most favor labels for prepared foods in the grocery store, too.

Women with atypical hyperplasia are at higher risk of breast cancer

Women with atypical hyperplasia of the breast have a higher risk of developing breast cancer than previously thought, a Mayo Clinic study has found. Results of the study appear in a special report on breast cancer in the New England Journal of Medicine.

Can exercise help people with Parkinson's disease?

Exercise may help people with Parkinson's disease improve their balance, ability to move around and quality of life, even if it does not reduce their risk of falling, according to a new study published in the December 31, 2014, online issue of Neurology, the medical journal of the American Academy of Neurology.

Rebleeds common post-capsule endoscopy for obscure GI bleeds

(HealthDay)—Nearly one-third of patients who undergo capsule endoscopy (CE) for obscure gastrointestinal bleeding (OGIB) have rebleeding a year or more later, according to research published online Dec. 15 in the Journal of Digestive Diseases.

More than 1.5 million cancer deaths averted during two decades of dropping mortality

The American Cancer Society's annual cancer statistics report finds that a 22% drop in cancer mortality over two decades led to the avoidance of more than 1.5 million cancer deaths that would have occurred if peak rates had persisted. And while cancer death rates have declined in every state, the report finds substantial variation in the magnitude of these declines, generally with the states in the south showing the smallest decline and in the Northeast the largest decline.

Researchers find significant link to daily physical activity, vascular health

As millions of Americans resolve to live healthier lives in 2015, research from the University of Missouri School of Medicine shows just how important diligent daily physical activity is. The researchers found that reducing daily physical activity for even a few days leads to decreases in the function of the inner lining of blood vessels in the legs of young, healthy subjects causing vascular dysfunction that can have prolonged effects.

New Year often ushers in pledge to quit drinking

(HealthDay)—People with drinking problems often make a New Year's pledge to stop or cut back on their drinking, but actually doing it can be a struggle, an addiction expert says.

Top UK doctor: Ebola screening should be improved (Update)

Five things to know: Obama health law again in play

New episodes in the nation's long-running political drama over health care are coming via your news feed in 2015.

Some businesses use part-time to meet health law

Many businesses in low-wage industries have hired more part-time workers and cut the hours of full-timers recently to soften the impact of new health law requirements that take effect Thursday, some consultants say.

Two patients test negative for Ebola in Britain

Two patients who recently returned from west Africa tested negative for Ebola in Britain on Wednesday as calls mounted for a review of airport screening procedures following a confirmed case this week.
