New findings could help target the bacteria that cause Lyme disease and syphilis

The bacterial pathogens that cause Lyme disease and syphilis are highly invasive. These pathogens, or spirochetes, can invade the central nervous system and, in the case of syphilis, enter the placenta, causing disease in the unborn child. In the November 19 issue of the Biophysical Journal, a Cell Press publication, researchers provide new insights into how these spirochetes penetrate tissue barriers. The findings might be used to develop new treatment strategies to help affected patients or even prevent infections.

Advanced CT imaging proves as accurate as invasive tests to assess heart blockages, study shows

An ultrafast, 320-detector computed tomography (CT) scanner that shows both anatomy within coronary arteries and blood flowcan accurately sort out which people need – or don't need – an invasive procedure to identify coronary blockages, according to an international study. The researchers say their findings could potentially save millions of people worldwide from having an unnecessary cardiac catheterization.

Study: Ureteral injury during robot-assisted prostate surgery

DETROIT – There may be warning signs to help surgeons avoid damaging part of the urinary system during robot-assisted surgical removal of prostate cancer, ultimately preventing the expense of additional surgery, according to researchers at Henry Ford's Vattikuti Urology Institute.

Although rare, they found instances when the ureter – tubes that carry urine from the kidneys to the bladder – were cut and required repair. In each case, they identified patient characteristics that may forewarn such damage. The study was recently published in the Journal of Endourology.

Social values vary across Canada

This news release is available in French.

Montreal, November 19, 2013 — Canada: true north, strong and free. But how strong are our beliefs? How free are our citizens? It depends where you live.

Demand for details on food labels includes the good -- and the bad

ITHACA, N.Y. – It's no surprise that labels are becoming the "go to" place when people have questions about how food is produced. But new Cornell University research finds that consumers crave more information, especially for the potentially harmful ingredients that aren't included in the product.

The laboratory study of 351 shoppers found consumers willing to pay a premium when a product label says "free of" something, but only if the package includes "negative" information on whatever the product is "free of."

New study reports on the high cost of cardiac surgery healthcare associated infections

After cardiac surgery, healthcare-associated infections (HAIs) are common complications associated with increased morbidity, mortality, and use of resources.

Study findings reported at the American Heart Association's Scientific Sessions 2013 by investigators from the Cardiothoracic Surgical Trials Network (CTSN), whose Data and Clinical Coordinating Center is at Icahn School of Medicine at Mount Sinai, revealed the substantial economic impact of HAIs following cardiac surgery and the importance of preventing these infections leading to re-hospitalizations.

Preschoolers can learn lasting heart-healthy lessons

Researchers identify a new genetic risk factor for severe psychiatric illness

MANHASSET, NY – Investigators at The Feinstein Institute for Medical Research have discovered a new genetic risk factor for schizophrenia and bipolar disorder called NDST3. The findings are published online in Nature Communications.

Origin of species: Protein imbalances doom hybrids

Why do crosses between closely related species fail to produce fertile hybrids? A new study led by Professor Axel Imhof of Ludwig-Maximilians-Universitaet (LMU) in Munich shows that differences in the levels - not necessarily the sequences - of certain key proteins are crucial in mediating reproductive isolation.

New study determines more accurate method to date tropical glacier moraines

A Dartmouth-led team has found a more accurate method to determine the ages of boulders deposited by tropical glaciers, findings that will likely influence previous research of how climate change has impacted ice masses around the equator.

The study appears in the journal Quaternary Geochronology. A PDF of the study is available on request.

New bale unroller design deemed effective

LEXINGTON, KY--John Wilhoit and Timothy Coolong from the University of Kentucky have introduced a new technology that can make the application of organic mulches more efficient. The research team from the University of Kentucky premiered their new invention in the August issue of HortTechnology. The team altered a conventional round-bale unroller and designed experiments to document its efficiency.

First-ever survey of Do-It-Yourself Biology community challenges myths

WASHINGTON—As the Do-It-Yourself Biology (DIYbio) community has grown, so have concerns among media and policymakers about these science enthusiasts' ability to wield DNA and manipulate life.

In 2009, for example, a Wall Street Journal headline summed up the popular misconception: "In Attics and Closets, 'Biohackers' Discover their Inner Frankenstein."

Non-specialist health workers play important role in improving mental health in developing countries

Non-specialist health workers are beneficial in providing treatment for people with mental, neurological and substance-abuse (MNS) problems in developing countries – where there is often a lack of mental health professionals – according to a new Cochrane review.
