Cranberry juice, long dissed as a mere folk remedy for relieving urinary tract infections in women, is finally getting some respect.

Thanks to Prof. Itzhak Ofek, a researcher at Tel Aviv University's Sackler Faculty of Medicine, the world now knows that science supports the folklore. Prof. Ofek's research on the tart berry over the past two decades shows that its juice indeed combats urinary tract infections.

And, he’s discovered, the refreshing red beverage has additional medicinal qualities as well. Prof. Ofek has found that cranberry juice exhibits anti-viral properties against the flu, can prevent cavities, and lessens the reoccurrence of gastric ulcers.

Methadone can be dangerous for some patients but is heroin a good idea for heroin addicts?

Maintenance treatment with heroin is appropriate for heroin misusers under certain circumstances, argue Jürgen Rehm from the Centre for Addiction and Mental Health in Toronto and Benedikt Fischer from the University of Victoria, British Columbia.

They point to trials in Switzerland, the Netherlands and Germany, which found heroin assisted maintenance treatment feasible and effective for those resistant to treatment.

In this week’s BMJ, doctors warn of excess sorbitol intake, a widely used sweetener in “sugar-free” products such as chewing gum and sweets.

Sorbitol has laxative properties and is poorly absorbed by the small intestine.

Their advice follows the cases of two patients with chronic diarrhea, abdominal pain and severe weight loss. Although extensive investigations were carried out, final diagnosis was only established after detailed analysis of eating habits.

New research challenges the generally accepted belief that substantial ice sheets could not have existed on Earth during past super-warm climate events.

The study by researchers at Scripps Institution of Oceanography at UC San Diego provides strong evidence that a glacial ice cap, about half the size of the modern day glacial ice sheet, existed 91 million years ago during a period of intense global warming.

Posted in Science, “Isotopic Evidence for Glaciation During the Cretaceous Supergreenhouse” examines geochemical and sea level data retrieved from marine microfossils deposited on the ocean floor 91 million years ago during the Cretaceous Thermal Maximum.

When nerve damage occurs, there are a few treatment options; microsurgery to sew two ends of the nerve together, using a nerve from another part of the body to replace a damaged section, or placing an empty tube between the cut ends so that nerve fibers can grow through it and back into the muscle.

Grafting a nerve from another part of the body is usually the most effective option, but it creates another injury site and isn’t possible in all patients. The tubes, known as nerve guidance conduits, cannot be used in gaps longer than three or four centimeters. In addition, nerve regeneration with this method is not always successful.

For the first time astronomers are able to see indirect evidence of dark matter and how this invisible force impacts on the crowded and violent lives of galaxies. University of British Columbia researcher Catherine Heymans has produced the highest resolution map of dark matter ever captured before.

Scientists believe that dark matter is the invisible web that houses galaxies. And as the universe evolves, the gravitational pull of this unseen matter causes galaxies to collide and swirl into superclusters.

Heymans and the University of Nottingham’s Meghan Gray led an international team to test this theory that dark matter determines the location of galaxies.

Continued from Part 3: I interviewed Gary Taubes by phone a few weeks ago, shortly after he gave a talk about the main ideas of his new book — Good Calories, Bad Calories — at UC Berkeley. The interview lasted about 2 hours. This is part 4.

SETH: I was impressed with the discussion in your book and lecture about obesity coexisting with poverty in all these different cultures and the implications of that. I’d never seen that before.

GARY TAUBES: I have this feeling, and I guess that all writers (or all neurotic writers) have to some extent, that my work is being ignored. It’s my Rodney Dangerfield complex. Now that I’ve written the book, I occasionally get emails from friends saying that they had some discussion with some obesity researcher, and they said, “Are you going to read Taubes’s book?” and their response was “Well, we know what Taubes thinks, so why should I bother reading the book?”

Deferoxamine (DF), originally used to treat iron poisoning, can significantly boost the body’s own ability to heal and re-grow injured bones, according to researchers at the University of Alabama at Birmingham (UAB).

The researchers injected deferoxamine into injured mouse bones. They found DF triggered the growth of new blood vessels, which in turn kicked off bone re-growth and healing.

In the study, bone density surrounding the injury more than doubled to 2.6 cubic millimeters in treated bones compared to 1.2 cubic millimeters in untreated bones, the researchers said.

The motion, formation, and recycling of Earth’s crust—commonly known as plate tectonics—have long been thought to be continuous processes but new research by geophysicists suggests that plate tectonic motions have occasionally stopped in Earth’s geologic history, and may do so again.

The findings could reshape our understanding of the history and evolution of the Earth’s crust and continents.

Synthesizing a wide range of observations and constructing a new theoretical model, researchers Paul Silver of the Carnegie Institution of Washington and Mark Behn of the Woods Hole Oceanographic Institution (WHOI) have found evidence that the process of subduction has effectively stopped at least once in Earth’s past.

If you’re worried about high cholesterol levels and keeping heart-healthy as you get older, don’t push aside bacon and eggs just yet. A new study says they might actually provide a benefit.

Researchers at Texas A&M University have discovered that lower cholesterol levels can actually reduce muscle gain with exercising. Lead investigator Steven Riechman, assistant professor of health and kinesiology, and Simon Sheather, head of the Department of Statistics, along with colleagues from The Johns Hopkins Weight Management Center and the Northern Ontario School of Medicine, have recently had their findings published in the Journal of Gerontology.

Bottom line: Before you have that second helping of oatmeal, it’s very possible that cholesterol may not be the mean Mr.
