German National Academy of Sciences Leopoldina submits statement on energy research

The German National Academy of Sciences Leopoldina has submitted an ad-hoc statement on energy research to Prof. Annette Schavan, the German Federal Minister of Education and Research. Against the backdrop of the events in Fukushima, the statement contains twelve key declarations that mainly address research-policy issues connected to the restructuring of Germany's energy system.

Treating children's eye infections without surgery

PROVIDENCE, R.I. – Researchers from Hasbro Children's Hospital in Providence, R.I., report that medical management may be preferred over surgery for children with orbital cellulitis, an acute infection of the tissues surrounding the eye. They have determined the criteria for surgical intervention should be dependent upon the size of a subperiosteal abscess (SPA). The research is published in the journal Ophthalmic Plastic & Reconstructive Surgery and is now available online in advance of print.

Flooding of farmland does not increase levels of potentially harmful flame retardants in milk

As millions of acres of farmland in the U.S. Midwest and South recover from Mississippi River flooding, scientists report that river flooding can increase levels of potentially harmful flame retardants in farm soils. But the higher levels apparently do not find their way into the milk produced by cows that graze on these lands, according to a study in the ACS journal Environmental Science & Technology.

Poplar tree leaf bud extract could fight skin aging

Antioxidants are popular anti-aging ingredients in skin creams, and now scientists are reporting a new source of these healthful substances — leaf buds of poplar trees. Their study appears in the ACS' Journal of Agricultural and Food Chemistry.

Progress in tissue engineering to repair joint damage in osteoarthritis

Medical scientists now have "clear" evidence that the damaged cartilage tissue in osteoarthritis and other painful joint disorders can be encouraged to regrow and regenerate, and are developing tissue engineering technology that could help millions of patients with those disorders. That's the conclusion of a new analysis of almost 100 scientific studies on the topic, published in ACS's journal Molecular Pharmaceutics.

What to do with bisphenol A: Ban it, restrict it, leave it alone?

Despite years of scientific studies, reports, lawsuits, congressional inquiries, claims and counterclaims, the question of whether bisphenol A (BPA) poses health threats to people lacks a definitive answer, according to a package of articles on the controversial substance in the current edition of Chemical & Engineering News (C&EN), ACS's weekly newsmagazine.

An alternative to antibiotics

The future of stem cell applications challenging, bright

An article in the current issue of Technology & Innovation, Proceedings of the National Academy of Inventors ™ reports on the bright future and enormous need for stem cell therapeutics that may offer hope for those suffering from debilitating and deadly diseases.

The cellular root of colorectal cancers?

June 8, 2011 – Researchers at Children's Hospital Boston have found a marker called ABCB5 that both tags a small proportion of cells within colorectal cancers and fuels resistance in those cells to standard treatments. The results indicate that eliminating ABCB5-expressing cells is crucial for successful colorectal cancer treatment, while adding to the growing body of evidence for a theory of cancer growth called the cancer stem cell hypothesis.

Study reveals how right-to-work laws impact store openings

WASHINGTON, DC, June 8, 2011 — A new study in the June issue of the American Sociological Review found evidence of how businesses engage in regulatory arbitrage and make decisions about where to open stores based on states' regulatory policies. The study explored various states' right-to-work (RTW) laws and Walmart store openings from 1998 through 2005.

Glaciations may have larger influence on biodiversity tan current climate

The study, published yesterday in the journal Ecology Letters, analyzed the species richness and the structure of their communities throughout the different regions of the European territory from the Ural Mountains to the Iberian Peninsula. The selection of this family of insects was motivated by their high dispersal ability and because their food sources (mainly cattle and sheep dung) are present throughout the continent.

Digital democracy? Study finds elite viewpoints dominate online content

Anyone with Internet access can generate online content and influence public opinion, according to popular belief. But a new study from the University of California, Berkeley, suggests that the social Web is becoming more of a playground for the affluent than a digital democracy.

Despite the proliferation of social media – with Twitter and Facebook touted as playing pivotal roles in such pro-democracy movements as the Arab Spring – the bulk of today's blogs, websites and video-sharing sites represent the perspectives of college-educated, Web 2.0-savvy users, the study says.

Adjuvant combo shows potential for universal influenza vaccine

Researchers at National Jewish Health have discovered how to prime a second arm of the immune system to potentially boost influenza vaccine effectiveness. A combination of two adjuvants, chemicals used to boost the effectiveness of some vaccines, induced CD8, or killer, T cells to join antibodies in response to influenza infection. Since the killer T cells targeted a highly conserved protein that does not change from year to year, the adjuvant strategy suggests potential for a universal flu vaccine.

Finnish twin study yields new information on how fat cells cope with obesity

The mechanisms by which obesity leads towards metabolic co-morbidities, such as diabetes mellitus, are poorly understood and of great public health interest. A study led by Matej Orešič from VTT Technical Research Centre of Finland suggests that adaptation of fat cell membranes to obesity may play a key role in the early stages of inflammatory disorders.

Circulating levels of a lung protein found to be 'strongly predictive' of cardiovascular disease

A blood protein known as surfactant protein-D (SP-D), which is mainly synthesised in the lungs, has been described as "a good predictor" of cardiovascular disease following a large study in North America. Reporting the study online today in the European Heart Journal, the investigators said that circulating SP-D levels were clearly associated with CVD and total mortality in patients with angiographically diagnosed coronary artery disease independent of other well established risk factors (such as age, smoking, cholesterol and C-reactive protein levels).(1)
