A Florida State University researcher has helped solve a scientific mystery that stumped chemists for nearly seven decades. In so doing, his team’s findings may lead to the development of more-powerful computer memories and lasers.

Naresh S. Dalal, the Dirac Professor of Chemistry and Biochemistry at FSU, recently collaborated with three colleagues, Jorge Lasave, Sergio Koval and Ricardo Migoni, all of the Universidad Nacional de Rosario in Argentina, to determine why a certain type of crystal known as ammonium dihydrogen phosphate, or ADP, behaves the way it does.

“ADP was discovered in 1938,” Dalal said. “It was observed to have some unusual electrical properties that weren’t fully understood -- and for nearly 70 years, scientists have been perplexed by these properties.

From absorbable sutures to gel-like cold-and-flu capsules, polymers have been used for years in the human body to help heal what ails us.

Today, scientists are pioneering the development of new “polymer drugs”--long-chained molecules that have therapeutic benefits because of their chemical composition and high molecular weight. The potential benefits of these novel drugs range from the more precise targeting of cancer-fighting chemotherapy treatments, to the sequestering and removal of toxins in the body.

Kristi Kiick, associate professor of materials science and engineering at the University of Delaware, recently published an article on polymer therapeutics in the prestigious journal Science.

Terrorists are leveraging information technology to learn how to create devastating weapons cheaply and quickly - and the West is now having to learn to keep up.

Since the start of the Iraq War, improvised explosive devices, or IEDs, have accounted for nearly half of the combat deaths reported by U.S. coalition forces. The death toll underscores a grim paradox of the ongoing conflict: during the last four and a half years the United States and its allies have fielded the most advanced and complex weaponry ever developed, but egg timers and toy remote controls in the hands of knowledgeable terrorists can do just as much damage.

Military analysts and counterterrorism experts say that this war is radically different from previous ones and must be thought of in an entirely new light.

Ubiquitin is a small protein, which can be attached to other cellular proteins. A study headed by the Junior Group of Dr. Daniel Krappmann (GSF - National Research Center for Environment and Health, Institute of Toxicology) in collaboration with Dr. Jürgen Ruland (TU Munich) and Dr. Claus Scheidereit (Max-Delbrück-Center , Berlin) now reports a novel finding about ubiquitination as a key event for the activation of an immune response.

The acquired immune response is triggered after specific engagement of foreign peptides (antigens) by receptor molecules on white blood cell (lymphocytes). Cellular signaling pathways are responsible for the activation of lymphocytes.

The Mandala is a detailed sand representation of the residence of the Medicine Buddha and one will be constructed by Tibetan monks over four days in Paris while simultaneously being displayed virtually in Second Life.

This confluence of technology and religion will get the message out about the situation in Burma, according to members of the Mind Science Institute and executives at a London think tank called Unfrozenmind, who have collaborated on the Second Life simulcast of the actual event.

Not everyone - okay, no one outside the Chinese government - is all that happy about things in Burma these days so they believe this will promote awareness of the situation there and aid Monks and Nuns of Burma in their efforts at independence.

With the latest advances in treatment, doctors say they can successfully neutralize the HIV virus. The so-called ‘combination therapy’ prevents the HIV virus from mutating and spreading, allowing patients to rebuild their immune system to the same levels as the rest of the population.

Professor Jens Lundgren from the University of Copenhagen, together with other members of the research group EuroSIDA, have conducted a study, which demonstrates that the immune system of all HIV-infected patients can be restored and normalized. The only stipulation is that patients begin and continue to follow their course of treatment.

Viruses are small organisms that have no independent metabolism. Consequently, when they enter the body they attack living cells and adopt their metabolism.

Groundbreaking - and heartwarmingly unessential - research done by University of Central Florida physics professor Costas Efthimiou has attempted to confirm what a generation of suicide girls has always feared - that vampires do not exist.

His reasoning? On Jan 1, 1600, the human population was just over 530 million people.

The governments of China and Brazil, exempt from Kyoto as developing nations yet still important polluters, commissioned a report from the InterAcademy Council that will be published Monday, October 22nd.  Its intent is to identify and detail the science, technology and policy framework for developing energy resources to drive economic growth in both developed and developing countries while also securing climate protection.

In animals with separate sexes, embryos commit to becoming male or female at an early stage. Often this key decision is made by sex determination genes on the sex chromosomes.

The genes involved in sexual development have changed remarkably little during evolution. In contrast, the sex determination genes and the sex chromosomes themselves are among the most rapidly changing features of the genome.

A research team formed by Sander van Doorn (Santa Fe Institute, USA) and Mark Kirkpatrick (University of Texas at Austin, USA) suggests an answer to the puzzle of why sex chromosomes evolve so rapidly. In a theoretical study published in the October 17, 2007 issue of NATURE they demonstrate that sexual conflict can establish novel sex-determining genes and sex chromosomes.

While acne is oftentimes as much a part of being a teenager as dating and Friday night football games, a new study examining the prevalence of acne in adults age 20 and older confirms that a significant proportion of adults continue to be plagued by acne well beyond the teenage years. In particular, women experience acne at higher rates than their male counterparts across all age groups 20 years and older.

In the study entitled, “The prevalence of acne in adults 20 years and older,” published online in the Journal of the American Academy of Dermatology, dermatologist Julie C.
