Compound in Grapes, Red Wine Could be Key to Fighting Prostate Cancer

MU researcher finds that prostate tumor cells are more susceptible to treatment after being exposed to resveratrol, a compound found in grape skins and red wine.

Resveratrol, a compound found commonly in grape skins and red wine, has been shown to have several beneficial effects on human health, including cardiovascular health and stroke prevention. Now, a University of Missouri researcher has discovered that the compound can make prostate tumor cells more susceptible to radiation treatment, increasing the chances of a full recovery from all types of prostate cancer, including aggressive tumors.

“Other studies have noted that resveratrol made tumor cells more susceptible to chemotherapy, and we wanted to see if it had the same effect for radiation therapy,” said Michael Nicholl, an assistant professor of surgical oncology in the MU School of Medicine. “We found that when exposed to the compound, the tumor cells were more susceptible to radiation treatment, but that the effect was greater than just treating with both compounds separately.” (more…)

IBM Helps Organizations Address Growing Mobile Computing Opportunity

Technology

New software and services enable businesses to create and enhance mobile strategies

ARMONK, N.Y. – 09 Nov 2012: IBM today unveiled a suite of new software and services that enables global organizations to build a comprehensive mobile computing strategy – from securing and managing devices, to creating mobile applications and analyzing data. These new offerings are part of a move by IBM to capitalize on the growing market opportunity for mobile that is expected to drive $130B in revenue for the IT industry by 2015, according to a recent study.[i]

As organizations increasingly view mobile computing as the next platform to conduct business, the market is evolving beyond just the device. Business leaders including the chief information officers (CIOs) and increasingly chief marketing officers (CMOs) of global organizations such as airlines, retailers, governments and healthcare providers are among the businesses turning to IBM to ensure mobile services and solutions are readily available to constituents and in full compliance with IT strategies. They need solutions that can be applied across any mobile environment and device — whether a laptop, smartphone or tablet — and can provide an underlying IT infrastructure that is always available, secure, effectively manages data, and integrates both front and back-end systems.

Folding Funnels Key to Biomimicry

Science

Berkeley Lab Finding that Protein Folding Funnels Also Apply to Self-Assembly Should Benefit Biomimicry and Nanosynthesis

Proteins are able to self-assemble into a wide range of highly ordered structures that feature a diverse array of properties. Through biomimicry – technological innovation inspired by nature – humans hope to emulate proteins and produce our own version of self-assembling molecules. A key to accomplishing this is understanding how protein-folding – a process critical to the form and function of a protein – is extended from individual proteins to complex assemblies. (more…)

Size Matters — Large CEO Signature Equals Small Performance

Economy, Small Business

COLLEGE PARK, Md – The size of a CEO’s signature can reveal a lot about that leader and company success. A large, embellished signature signals a heavy narcissist and diminished firm performance, concludes a study of 400 CEO signatures by researchers in the University of Maryland’s Robert H. Smith School of Business. (more…)

Exhaustive Family Tree for Birds Shows Recent, Rapid Diversification

Nature

A Yale-led scientific team has produced the most comprehensive family tree for birds to date, connecting all living bird species — nearly 10,000 in total — and revealing surprising new details about their evolutionary history and its geographic context.

Analysis of the family tree shows when and where birds diversified — and that birds’ diversification rate has increased over the last 50 million years, challenging the conventional wisdom of biodiversity experts.

“It’s the first time that we have — for such a large group of species and with such a high degree of confidence — the full global picture of diversification in time and space,” said biologist Walter Jetz of Yale, lead author of the team’s research paper, published Oct. 31 online in the journal Nature.

Sharks: Bad Creatures or Bad Image?

Media, Nature

EAST LANSING, Mich. — Historically, the media have been particularly harsh to sharks, and it’s affecting their survival.

The results of a Michigan State University study, appearing in the current issue of the journal Conservation Biology, reviewed worldwide media coverage of sharks – and the majority isn’t good.

Australian and U.S. news articles were more likely to focus on negative reports featuring sharks and shark attacks rather than conservation efforts. Allowing such articles to dominate the overall news coverage diverts attention from key issues, such as shark populations are declining worldwide and many species are facing extinction, said Meredith Gore, MSU assistant professor of fisheries and wildlife and the School of Criminal Justice.
