Starving cancer the key to new treatments, say scientists

Thu, 05/05/2016 - 2:47pm
Researchers have identified a vital supply route that cancer cells use to obtain their nutrients, in a discovery that could lead to new treatments to stop the growth of tumors. The research team blocked gateways through which the cancer cell was obtaining the amino acid glutamine and found the cells almost completely stopped growing.

Clinical study suggests the origin of glioblastoma subtypes

Thu, 05/05/2016 - 12:57pm
Researchers have demonstrated that distinct types of glioblastoma, the most common form of brain cancer in adults, tend to develop in different regions of the brain. This finding provides an explanation for how the same cancer-causing mutation can give rise to different types of brain malignancies.

How to talk about climate change so people will act

Thu, 05/05/2016 - 12:57pm
Framing the issue of climate change collectively is more effective than emphasis on personal responsibility, finds a new study. People are willing to donate up to 50 percent more cash to the cause when thinking in collective terms. Thinking about climate change from a personal perspective produced little to no change in behavior.

Atrial fibrillation patients treated with warfarin have higher rates of dementia, new study finds

Thu, 05/05/2016 - 12:57pm
Study of more than 10,000 patients treated long term with the blood thinner, warfarin, reveals higher rates of dementia for patients with atrial fibrillation versus non-AF patients.

Study contradicts belief that cancer protects against Alzheimer's

Thu, 05/05/2016 - 12:57pm
Despite studies that claim people with cancer are less likely to develop Alzheimer’s disease--raising the possibility that what triggers cancer also prevents the neurodegenerative disorder--a new investigation finds a more somber explanation. Many cancer patients don’t live long enough to get Alzheimer’s.

Floods, coastal erosion may expose contents of UK landfills, study finds

Thu, 05/05/2016 - 12:55pm
The contents of historic coastal landfill sites could pose a significant environmental threat if they erode, according to a new study. There are 1264 historic coastal landfill sites in England and Wales, all of which are sealed and no longer receive waste, but fall wholly or partially within the Environment Agency’s Tidal Flood Zone 3.

Physicists explore superconductivity at the two-dimensional limit

Thu, 05/05/2016 - 12:55pm
Researchers show that the superconducting state can be maintained even when the material in question is reduced from three to two dimensions, making the efficiency gains needed for technologies like those underlying the frictionless train possible.

Cells check DNA segregation at the end of their division

Thu, 05/05/2016 - 12:54pm
Researchers are shedding new light on the cell division process, key in embryonic development, and the growth and proliferation of tumors. The study identifies the agents that prevent cells from separating when DNA division is defective.

Heavy body shape across lifespan associated with highest mortality

Thu, 05/05/2016 - 12:53pm
People who are lean for life have the lowest mortality, while those with a heavy body shape from childhood up to middle age have the highest mortality, reveal findings of a large study.

Extreme ICU: 5 percent of patients account for 33 percent of intensive care, need special focus

Thu, 05/05/2016 - 12:53pm
Every hospital's ICU has treated them -- the critically ill patients who spend weeks going from crisis to crisis, never quite getting better enough to get out of the ICU, but never quite dying. Now, research shows they really are a different kind of patient -- and that despite their tiny numbers, they're using a vast chunk of healthcare resources. Just 5 percent of ICU patients account for 33 percent of all days ICU beds get used, report investigators.

Detailed digital human models could hold key to future clinical research

Thu, 05/05/2016 - 12:53pm
Computer simulations of disease processes and detailed digital models of our organs could provide more accurate monitoring and outcome measurements for clinical trials, according to research.

Timed-release glaucoma drug insert shows promise as alternative to daily drops

Thu, 05/05/2016 - 12:53pm
A medicated silicone ring that rests on the surface of the eye and slowly releases medication reduced eye pressure in glaucoma patients by about 20 percent over six months. These clinical trial results are the first published research on this type of continuous glaucoma drug delivery technology, which could benefit nearly 3 million people with glaucoma in the United States.

Driving under the influence sounds like a better idea while high on marijuana

Wed, 04/05/2016 - 9:53pm
A new study found that marijuana users who were high at the time they took the survey had substantially higher odds of believing it was safe to drive while under the influence.

Newborn screening for cystic fibrosis

Wed, 04/05/2016 - 9:49pm
The benefits of newborn screening for cystic fibrosis (CF) patients has been reinforced by new research. The findings add to the increasingly overwhelming evidence in favor of newborn screening as a way to improve the quality of life for patients living with this chronic disease that is still incurable.

Biological 'good guy' has a dark side, researchers find

Wed, 04/05/2016 - 9:48pm
A pair of scientists has discovered that an enzyme previously thought only to be beneficial could, in fact, pose significant danger to developing embryos. The new research could have implications not only for prenatal development but also for treating lymphedema and liver damage resulting from acetaminophen overdose.

Findings light the way for new treatments in colitis, colon cancer

Wed, 04/05/2016 - 9:48pm
Certain sugars produced by the body play an important role in the development of colitis and, ultimately, colon cancer. This new finding could potentially lead to therapies for ulcerative colitis, Crohn's disease and colon cancer.

Breast milk hormones found to impact bacterial development in infants' guts

Wed, 04/05/2016 - 9:48pm
A new study finds that hormones in breast milk may impact the development of healthy bacteria in infants' guts, potentially protecting them from intestinal inflammation, obesity and other diseases later in life.

Women ratchet themselves up the social ladder, one high heel at a time

Wed, 04/05/2016 - 9:48pm
Fashion seems to embrace two opposite goals -- fitting in with the crowd and standing out from it. Now new research reveals that the choice to fit in or stand out depends on who exactly the crowd is -- and the size of their high heels. That is, women adjust their fashion to look similar to the rich but different from the poor.
