Egyptian Ministry of Higher Education and Scientific Research and Harbor Branch Oceanographic Institute at FAU Pledge to Cooperate on Oceanographic Research and Education--Scientists will work jointly to advance marine research in the Red Sea.
Florida Atlantic University and the Egyptian Ministry of Higher Education and Scientific Research have signed an agreement to cooperate on a range of ocea
The virus that causes winter vomiting disease invades cells by attaching to particular sugar molecules on the surface of the cells. This is the conclusion of a thesis presented at the Sahlgrenska Academy, University of Gothenburg, Sweden. This result may be an important step in the development of a drug against the regular hospital-based epidemics caused by the virus.
In what could be a major pharmaceutical breakthrough, research published online in The FASEB Journal (http://www.fasebj.org) describes how scientists from St George's, University of London have devised a one-two punch to stop HIV.
DENVER - A combination of two targeted therapies packs a powerful punch to kill pancreatic cancer cells in the laboratory, Mayo Clinic cancer researchers report.
For centuries, people have preserved fruit by mixing it with sugar, making thick jams that last for months without spoiling. Now scientists at the National Institute of Standards and Technology (NIST) have discovered* a fundamental property of mixture behavior that might help extend the life of many things including vaccines, food and library books -- and save money while doing it.
Researchers may be able to "freeze" water into a solid, not by cooling but by confining it to narrow spaces less than one-millionth of a millimeter wide, according to new results from an interdisciplinary team of scientists and engineers.
Researchers at the University of California, Riverside have discovered the world's strongest acid. Remarkably it is also the gentlest acid. This non-toxic and non-corrosive acid may have a role in processes such as improving the quality of gasoline, developing polymers and synthesizing pharmaceuticals. So how can an acid be both strong and gentle? The answer lies in the way chemists define the strength of an acid.
What happens to painkillers, antibiotics and other medicines after their work is done, and they end up in the wastewater stream? The National Institute of Standards and Technology is using laboratory experiments to help answer this question by studying what happens to pharmaceuticals when they react with chlorine--a disinfectant commonly used in wastewater treatment.
Researchers have demonstrated a simple way to reduce the toxicity of water-soluble buckyballs by a factor of more than ten million. Buckyballs, whose chemical notation is C60, are hollow, soccerball-shaped molecules containing 60 carbon atoms. Their diameter is just one-billionth of a meter, or one nanometer, and their discovery is widely regarded as an early milestone in the field of nanotechnology. While buckyballs show great promise in applications as diverse as fuel cells, batteries, pharmaceuticals and coatings, some scientists and activists have raised concerns about their potential toxicity to humans and animals.
A handful of genes in a morphine free poppy could hold the key to producing improved pain management pharmaceuticals. Norman, the 'no-morphine' poppy, is superior to morphine producing poppies as it produces thebaine and oripavine -- compounds preferred by industry in the manufacture of alternative high value pain-killers. ''The genes we found behaved differently in Norman compared to standard morphine producing poppies and were consistently associated with the blockage in morphine synthesis and with the accumulation of thebaine and oripavine.''
From mollusks to mammals, newly discovered chemical pathways of serotonin in the nervous system are paving a path toward future pharmaceutical treatments for depression and other disorders. ''Understanding novel serotonin pathways in a tissue-dependent manner is useful for the development of pharmaceuticals intended to preserve serotonergic signaling,'' said researcher Jeffrey Stuart. Serotonin is a neurotransmitter present throughout the body. When nerve cells containing it are activated, serotonin is released. It travels and stimulates other nerve cells, enabling their message to spread through the nervous system.
Building on an idea developed by medicinal chemists, researchers have devised a new mathematical tool that accurately predicts how long certain pollutants -- including pesticides and pharmaceuticals -- will remain in soil. The work is timely because researchers and public officials have become increasingly concerned about pharmaceuticals and personal care products that have been detected in soil and water. Environmental engineers are seeking better ways to track these emerging pollutants, which tend to be more complex and water-soluble than previous contaminants of concern, such as chlorinated solvents and petroleum byproducts.
In a remarkable collaboration between engineers, physicists and biologists, Princeton scientists have invented a device that rapidly sorts microscopic particles into extremely fine gradations of sizes, opening a range of potential uses. The researchers have used the device to sort particles ranging in size from bacterial cells to large segments of DNA and reported their results in the May 14 issue of Science. The technology could greatly accelerate the work of sequencing genomes and could find uses in many other areas, from improving the performance of pharmaceuticals to detecting bioterrorism agents.
Eye diseases like glaucoma could one day be treated by pharmaceuticals delivered through contact lenses. Chemical engineers from the University of Florida say they've been able to make soft contact lenses containing tiny embedded particles that slowly release drugs directly where they're needed. The research was presented today at the 225th national meeting of the American Chemical Society, the world's largest scientific society, held this week in New Orleans.
European researchers say new imaging technology has come to life with the capturing of the world's first terahertz picture of a human hand. This advancement in terahertz imaging opens up the possibility for a new generation of applications, not only related to space but also in many non-space fields, including medicine, pharmaceuticals, security and aeronautics.
