Antifungal compound found on tropical seaweed has promising antimalarial properties

Other Georgia Tech researchers have begun research on synthesizing the compound in the laboratory. Beyond producing quantities sufficient for testing, laboratory synthesis may be able to modify the compound to improve its activity – or to lessen any side effects. Ultimately, yeast or another microorganism may be able to be modified genetically to grow large amounts of bromophycolide.

Increasing triglyceride levels linked to greater stroke risk

A study by researchers in Denmark revealed that increasing levels of non-fasting triglycerides are associated with an increased risk of ischemic stroke in men and women. Higher cholesterol levels were associated with greater stroke risk in men only. Details of this novel, 33-year study are now available online in Annals of Neurology, a journal published by Wiley-Blackwell on behalf of the American Neurological Association.

Reprogrammed stem cells hit a roadblock

It's a discordant note in the symphony of good news that usually accompanies stem cell research announcements. Stem cells hold enormous promise in regenerative medicine, thanks to their ability to regenerate diseased or damaged tissues. They have made it possible to markedly improve the effectiveness of many medical treatments – muscle regeneration in cases of dystrophy, skin grafts for treating burn victims, and the treatment of leukemia via bone marrow transplants.

Macavity wasn't there! How absent reoviruses kill cancer

Reoviruses are successfully being used in clinical trials to treat patients with cancer. Not only does the virus cause cancer cells to die, it also forces them to release pro-inflammatory chemokines and cytokines, which in turn causes the patient's immune system to attack the disease. New research published by BioMed Central's open access journal Molecular Cancer shows that reovirus infected cancer cells secrete proteins which, even when isolated, result in the death of cancer cells.

Floating spores kill malaria mosquito larvae

There are over 200 million cases of malaria each year and, according to the World Health Organisation, in 2009 malaria was responsible for 781,000 deaths worldwide. Malaria is spread by mosquitoes which breed in open water and spend much of their larval stage feeding on fungi and microorganisms at the water surface. New research published in BioMed Central's open access journal Parasites and Vectors presents a method of dispersing pathogenic fungi as a means of preventing the spread of malaria.

Groundbreaking technology will revolutionize blood pressure measurement

In a major scientific breakthrough, a new blood pressure measurement device is set to revolutionise the way patients' blood pressure is measured.

The new approach, invented by scientists at the University of Leicester and in Singapore, has the potential to enable doctors to treat their patients more effectively because it gives a more accurate reading than the current method used. It does this by measuring the pressure close to the heart – the central aortic systolic pressure or CASP.

One Health: From ideas to implementation, rhetoric to reality

Washington—February 17, 2011--The convergence of people, animals, and our environment has created a new dynamic in which the health of each group is inextricably and globally interconnected, without borders. It is against this background that One Health has emerged as a multidisciplinary effort to attain optimal health of humans, animals and our environment.

Earth's core rotating faster than rest of the planet but slower than previously believed

New research gives the first accurate estimate of how much faster the Earth's core is rotating compared to the rest of the planet.

Previous research had shown that the Earth's core rotates faster than the rest of the planet. However, scientists from the University of Cambridge have discovered that earlier estimates of 1 degree every year were inaccurate and that the core is actually moving much slower than previously believed – approximately 1 degree every million years. Their findings are published today, Sunday 20 February, in the journal Nature Geoscience.

Trichinosis parasite gets DNA decoded

The new research also has implications far beyond a single parasitic disease, the researchers say. T. spiralis is just one of many thousands of parasitic roundworms called nematodes that, according to the World Health Organization, infect 2 billion people worldwide, severely sickening 300 million. Other species of parasitic nematodes cause diseases in pets and livestock and billions of dollars of crop losses annually.

Family planning programs have success in developing countries, but need to be expanded

COLUMBUS, Ohio – While many researchers generally credit the desire for smaller families for the decline in fertility rates in developing, low-income countries, new research suggests that prevention of unwanted births may actually be a larger factor.

The advent of safe and more effective birth control means that people have better control of when and if they have children, said John Casterline, director of the Initiative in Population Research at Ohio State University.

It's time to take a unified approach toward measuring sustainability

EAST LANSING, Mich. — Ask any political leader if they are in favor of sustainability, and the pat answer is typically a resounding, "Yes."

Evaluating its effectiveness, however, is a much trickier endeavor. Thomas Dietz, a sociology and environmental science and policy professor at Michigan State University, took steps to indentify a universal framework to evaluate sustainability at a national gathering of scientists Feb. 20.

Water, water, everywhere… but is it safe to drink?

"Over the last couple of generations, there has been a huge amount of groundwater pollution worldwide, and this has had a negative impact on our drinking water supply," says Barbara Sherwood Lollar, Canada Research Chair in Isotope Geochemistry of the Earth and the Environment at the University of Toronto.

The world’s oldest water?

Washington — New evidence bolsters the notion that deep saline groundwaters in South Africa's Witwatersrand Basin may have remained isolated for many thousands, perhaps even millions, of years.

The study, recently accepted for publication in Chemical Geology, found the noble gas neon dissolved in water in three-kilometre deep crevices.

'Universal standards' for research integrity may have unintended consequences

The global scientific community is capable of policing its own behavior and should resist creation of a central oversight body to enforce 'universal standards' that may have unintended consequences, a renowned physicist and director of the Energy Institute at the University of Texas at Austin said Saturday.

A new high-resolution method for imaging below the skin using a liquid lens

University of Rochester optics professor Jannick Rolland has developed an optical technology that provides unprecedented images under the skin's surface. The aim of the technology is to detect and examine skin lesions to determine whether they are benign or cancerous without having to cut the suspected tumor out of the skin and analyze it in the lab. Instead, the tip of a roughly one-foot-long cylindrical probe is placed in contact with the tissue, and within seconds a clear, high-resolution, 3D image of what lies below the surface emerges.
