Is transparency bad for science?

As thousands more emails from the University of East Anglia's Climatic Research Unit (CRU) are leaked on the internet, the latest issue of Index on Censorship magazine, 'Dark Matter', calls for a debate into science and transparency.

Interethnic marriage between African- and Native-Americans produced many children

American Indians with African ancestry outdid 'full bloods' in reproductive terms in the early 1900s, despite the odds being against them, according to a new study by Michael Logan from the University of Tennessee in the US. Their increased fertility occurred at a time when things were not going particularly well for full bloods either - in social, economic and health terms. The work is published online in Springer's journal, Human Ecology.

Scientists use laser imaging to assess safety of zinc oxide nanoparticles in sunscreen

WASHINGTON, Nov. 30—Ultra-tiny zinc oxide (ZnO) particles with dimensions less than one-ten-millionth of a meter are among the ingredients list of some commercially available sunscreen products, raising concerns about whether the particles may be absorbed beneath the outer layer of skin. To help answer these safety questions, an international team of scientists from Australia and Switzerland have developed a way to optically test the concentration of ZnO nanoparticles at different skin depths.

A Spanish botanist searches for prehistoric flora refuges in China

Jordi López of the Barcelona Botanical Institute has joined local researchers in a study to locate and define "havens and museums of flora" in China – areas where vegetation resisted the glaciations of the Quaternary Period.

Researchers' new recipe cooks up better tissue 'phantoms'

WASHINGTON, Nov. 30—The precise blending of tiny particles and multicolor dyes transforms gelatin into a realistic surrogate for human tissue. These tissue mimics, known as "phantoms," provide an accurate proving ground for new photoacoustic and ultrasonic imaging technologies.

BUSM researchers develop blood test to detect membranous nephropathy

(Boston) – Research conducted by a pair of physicians at Boston University School of Medicine (BUSM) and Boston Medical Center (BMC) has led to the development of a test that can help diagnose membranous nephropathy in its early stages. The test, which is currently only offered in the research setting and is awaiting commercial development, could have significant implications in the diagnosis and treatment of the disease. Currently, the only way to diagnose the disease is through a biopsy.

UC research examines home births -- then and now

A comparison of home-birth trends of the 1970s finds many similarities – and some differences – related to current trends in home births.

For instance, in the 1970s – as now – women opting to engage in home births tended to have higher levels of education. That's according to a 1978 survey by Home Oriented Maternity Experience (HOME) that was recently found by University of Cincinnati historian Wendy Kline in the archives of the American Congress of Obstetricians and Gynecologists (ACOG).

The newest of the new in gene therapy: 'Tag and target and exchange'

Bethesda, MD—A combination of two techniques promises to improve the efficiency and effectiveness of experimental gene therapies, while also reducing potential side effects says a new research report published in the December 2011 issue of the FASEB Journal (http://www.fasebj.org).

Dieters should eat foods rich in protein, mostly from dairy, to protect bones during weight loss

New research suggests that a calorie-restricted diet higher in protein—mostly from dairy foods—and lower in carbohydrates coupled with daily exercise has a major positive impact on bone health in overweight and obese young women.

The study, published online in the Journal of Clinical Endocrinology and Metabolism, found bone health improvements were particularly evident due to the high density of bone-supporting nutrients such as calcium, vitamin D and dairy-based protein.

Marzipan Santas, elves and stollen: Real deal or cheap fakes?

With the December holidays a peak season for indulging in marzipan, scientists are reporting development of a new test that can tell the difference between the real thing — a pricey but luscious paste made from ground almonds and sugar — and cheap fakes made from ground soy, peas and other ingredients. The report appears in ACS' Journal of Agricultural and Food Chemistry.

Stinky frogs are a treasure trove of antibiotic substances

Some of the nastiest smelling creatures on Earth have skin that produces the greatest known variety of anti-bacterial substances that hold promise for becoming new weapons in the battle against antibiotic-resistant infections, scientists are reporting. Their research on amphibians so smelly (like rotten fish, for instance) that scientists term them "odorous frogs" appears in ACS' Journal of Proteome Research.

Engineered botulism toxins could have broader role in medicine

The most poisonous substance on Earth — already used medically in small doses to treat certain nerve disorders and facial wrinkles — could be re-engineered for an expanded role in helping millions of people with rheumatoid arthritis, asthma, psoriasis and other diseases, scientists are reporting. Their study appears in ACS' journal Biochemistry.

Scientists discover anti-inflammatory polyphenols in apple peels

Bethesda, MD—Here's another reason why "an apple a day keeps the doctor away"—according to new research findings published in the Journal of Leukocyte Biology (https://www.jleukbio.org), oral ingestion of apple polyphenols (antioxidants found in apple peels) can suppress T cell activation to prevent colitis in mice.

Hebrew University researchers discover molecular machinery for bacterial cell death

Jerusalem, Nov. 29, 2011 – Researchers at the Hebrew University of Jerusalem and the University of Vienna have revealed for the first time a stress-induced machinery of protein synthesis that is involved in bringing about cell death in bacteria.

First analysis of tumor-suppressor interactions with whole genome in normal human cells

UPTON, NY — Scientists investigating the interactions, or binding patterns, of a major tumor-suppressor protein known as p53 with the entire genome in normal human cells have turned up key differences from those observed in cancer cells. The distinct binding patterns reflect differences in the chromatin (the way DNA is packed with proteins), which may be important for understanding the function of the tumor suppressor protein in cancer cells. The study was conducted by scientists at the U.S.
