How to Effectively Compare Auto Insurance Quotes

As the economy of the world continues to fluctuate and the unemployment rates remain high even in the most stable first world economies, people everywhere are looking for ways to cut back their monthly budgets. One of the first things that is usually on the chopping block are the various insurance packages that people consider a luxury.

Although this is perhaps the least advisable way to lower monthly liabilities, many people think that it is their only option. They believe that prices on things like car insurance and home insurance are set in stone, and that they cannot be negotiated down. This notion is far from the truth. (more…)

Crocodilian Evolution

UD’s Schmidt studies genome of crocodile family in evolution research

University of Delaware scientist Carl Schmidt is working to identify genes in crocodiles, alligators and gharials as he searches for links between the creatures that could give clues as to how they evolved over the years in relation to one another.

Schmidt’s effort is part of a National Science Foundation-funded project being conducted by a team of researchers assembled by David Ray, an evolutionary biologist at Mississippi State University. (more…)

Student Documentary Explores Facebook- and Fast-Food-Free Life

EAST LANSING, Mich. — In a society where people text rather than talk and eat out more than cook, community has been lost and necessities replaced by wants, says a group of Michigan State University students who recently released a documentary of their monthlong experiment in living with less.

Apple, Amazon Dominating Tablet, E-reader Market, RJI Survey Shows

Mobile devices not replacing printed newspapers as quickly as earlier predicted, MU expert says

COLUMBIA, Mo. — Two-thirds of U.S. adults now use at least one mobile media device in their daily lives, according to a national survey recently conducted by the Reynolds Journalism Institute (RJI) at the University of Missouri School of Journalism. The RJI survey found that news consumption ranks fourth among reasons people use mobile devices, behind interpersonal communications, entertainment, and Internet usage for information not provided by news organizations. Despite the large number of mobile device users, Roger Fidler, the program director for digital publishing at RJI, says that mobile news products do not appear to be replacing printed newspapers as quickly as was earlier predicted.

Evolution of Religious Patriarchy as a Mate-Guarding Strategy?

One of the largest and longest studies in a traditional African society sheds light on religious practices and cuckoldry. Genetic data suggest religious patriarchy is directly analogous to the mate-guarding tactics used by animals to ensure paternity.

Religious practices that strongly control female sexuality are more successful at promoting certainty about paternity, according to a study published in the June 4, 2012 issue of the Proceedings of the National Academy of Sciences.

In an interdisciplinary collaboration, a group of researchers around biological anthropologist Beverly Strassmann from the University of Michigan and University of Arizona geneticist Michael Hammer analyzed genetic data on 1,706 father-son pairs in a traditional African population – the Dogon people of Mali, West Africa – in which Islam, two types of Christianity and an indigenous, monotheistic religion are practiced in the same families and villages.

Resident Evil: Retribution

Synopsis

The Umbrella Corporation’s deadly T-virus continues to ravage the Earth, transforming the global population into legions of the flesh eating Undead. The human race’s last and only hope, Alice, awakens in the heart of Umbrella’s most clandestine operations facility and unveils more of her mysterious past as she delves further into the complex. Without a safe haven, Alice continues to hunt those responsible for the outbreak; a chase that takes her from Tokyo to New York, Washington, D.C. and Moscow, culminating in a mind-blowing revelation that will force her to rethink everything that she once thought to be true. Aided by newfound allies and familiar friends, Alice must fight to survive long enough to escape a hostile world on the brink of oblivion. The countdown has begun. (more…)

A New Way of Looking at Photosystem II

Berkeley Lab and SLAC Researchers Study Key Protein Complex Crucial to Photosynthesis

Future prospects for clean, green, renewable energy may hinge upon our ability to mimic and improve upon photosynthesis – the process by which green plants, algae and some bacteria convert solar energy into electrochemical energy. An artificial version of photosynthesis, for example, could use sunlight to produce liquid fuels from nothing more than carbon dioxide and water. First, however, scientists need a better understanding of how a large complex of proteins, called photosystem II, is able to split water molecules into oxygen, electrons and hydrogen ions (protons). A new road to reaching this understanding has now been opened by an international team of researchers, led by scientists at the U.S. Department of Energy (DOE)’s Lawrence Berkeley National Laboratory (Berkeley Lab) and SLAC National Accelerator Laboratory.

Using ultrafast, intensely bright pulses of X-rays from SLAC’s Linac Coherent Light Source (LCLS), the research team produced the first ever images at room temperature of microcrystals of the photosystem II complex. Previous imaging studies, using X-rays generated via synchrotron radiation sources, required cryogenic freezing, which alters the samples. Also, to catalyze its reactions, photosystem II relies upon an enzyme that contains a manganese-calcium cluster that is highly sensitive to radiation. With the high-intensity femtosecond X-ray pulses of the LCLS, the research team was able to record intact images of these clusters before the radiation destroyed them. (more…)

Anxious Women’s Brains Work Harder

EAST LANSING, Mich. — In a discovery that could help in the identification and treatment of anxiety disorders, Michigan State University scientists say the brains of anxious women work much harder than those of men. (more…)
