Personally, I’ve never had a problem with a fear of flying, a lot of people suffer from this often debilitating phobia though despite reassurances about road death statistics being much worse than air crashes. That said perhaps there is one aspect of flying that should be of concern - exposure to radiation from outer space, [...]Post from: Sciencebase Science Blog... Read more »

Marc Ostfield is the Senior Advisor for Bioterrorism, Biodefense, and Health Security, US Department of State, Office of International Health and Biodefense in Washington DC and believes that the concept of biosecurity as a primary strategy to combat terrorism is nothing more than an illusion.
As a concept biosecurity, also known as pathogen security, suggests that [...]Post from: Sciencebase Science Blog... Read more »

Researchers in Argentina have developed a new approach to testing food packaging for trace amounts of the toxic heavy metal cadmium.
Cadmium is one of several additives used extensively in the manufacture of plastics. Regulations limit the concentration of cadmium allowable, of course. In the European Union that limit is 100 milligrams per kilogram. But, the [...]Post from: Sciencebase Science Blog... Read more »

Having discussed the possible environmental risks of charitable aid in the form of obsolete electronic goods to the developing world, it seemed to timely to mention other research looking into strong solutions to some of the critical problems facing people in many parts of the world.
Researchers, Priti Parikh and Allan McRobie, in Cambridge, England, suggest [...]Post from: Sciencebase Science Blog... Read more »
Charitable schemes to send unwanted electronic equipment, including mobile phones and computers to the developing world could be creating more environmental problems than they solve if the equipment becomes entirely obsolete in a short time. Researchers in India have carried out an evaluation of the trade-offs between cost and environmental risks to prove the point.
There [...]Post from: Sciencebase Science Blog... Read more »

Swine flu (H1N1) information leaflets are being delivered to households across the UK today. I suspect they do nothing but increase fear and confuse people, especially as the WHO/UN are about to lower the swine flu alert level.
In the UK, 27 people now have the virus, with 23 in England and four in Scotland and [...]Post from: Sciencebase Science Blog... Read more »

Are digital inclusion projects in the developing world booming or are they doomed to failure? That’s the question asked by legal expert Dinusha Mendis of the University of Central Lancashire, Preston, UK.
Mendis has investigated the digital divide in Bangladesh, Sri Lanka, and Nigeria, and how laws such as those governing intellectual property rights and copyright [...]Post from: Sciencebase Science Blog... Read more »

It’s a crude schoolroom axiom around which many an adult pub debate might also revolve: He who smelt it, dealt it.
However, there is a serious side to quickly locating the source of noxious odours in an indoor environment of varying airflow, as Zhenzhang Liu and Tien-Fu Lu of The University of Adelaide, Australia, will attest. [...]Post from: Sciencebase Science Blog... Read more »

Across the globe privacy laws and property rights are confused. Having usually been established in centuries past it is unlikely that any established legal system can cope easily with the requirements of the digital age. Nowhere is this more likely to hold true than when discussing the use of peoples’ biometric information, which are very [...]Post from: Sciencebase Science Blog... Read more »

The medicalization of many social facets of our lives, multitasking pharmaceuticals and disease mongering are problems we should face head one.
The overlap between business ethics and medical ethics represent a moral minefield. Nowhere more so than in the domain of newly recognised and previously untreated disorders, syndromes and diseases, among them social anxiety disorder, non-physiological [...]Post from: Sciencebase Science Blog...

The difference between staying in with friends and going out? Obvious, really. But, translate that idea to networks and you have the basis of self-organized virtual communities, according to Panayotis Antoniadis of the Université Pierre et Marie Curie, in Paris France.

“Nothing beats finding vast lakes of oil for the pumping, or vast deposits of coal for the digging; thanks mother nature!” proclaimed Craig Grimes of Penn State University in an emailed response to my skeptical question regarding his work on catalysts that can convert the greenhouse gas carbon dioxide into a fuel, methane.

During my student days, one of the most obviously complicated and beyond-comprehension modules was that on fluid dynamics. It’s not surprising that it was complicated and beyond comprehension, the way fluids (gases and liquids by definition) move is not simple.
There is no single, straightforward equation that can describe the flow of water cascading down waterfall. [...]Post from: Sciencebase Science Blog... Read more »

Compulsory licensing is one of those euphemisms that hide a whole raft of issues. By definition - it is “authorisation to a government or company to make and sell a pharmaceutical drug without the permission of the patent holder”, which makes the intent clear.
In its most obvious form, compulsory licensing is what occurs when a [...]Post from: Sciencebase Science Blog... Read more »

In 2004, I did some reportage for the Royal Society from their meeting on emerging viral infections. The meeting was held just after the worldwide SARS outbreak that threw nations into chaos and had the more susceptible parts of the media hyping the end of the world. Of course, SARS, an emerging pathogen, was lethal [...]Post from: Sciencebase Science Blog... Read more »

In the long-gone days of my Catalyst column on the original ChemWeb.com, I wrote about how R&D was becoming a distributed endeavour. It was going the way of large-scale data problems that are best solved using a distributed computing environment, or Grid. Now, roughly a decade later, it seems the management of globally dispersed R&D [...]Post from: Sciencebase Science Blog... Read more »
Following on from Monday’s post about health information on twitter, it seemed a nice coincidence that I came across a research paper focusing on healthcare information available in the developing world.

With regulations set to ban incandescent light bulbs, the illuminating invention we’ve used since the nineteenth century, a replacement is needed. LEDs hold promise but are dim compared with the bulbs they seek to replace. Compact fluorescent tubes, are a bright idea. They are essentially a miniaturised version of the strip lighting by which shoppers [...]Post from: Sciencebase Science Blog... Read more »

I recently reported on the spit test being developed for autism spectrum disorder (ASD). It’s in the very early stages of development (this is not an antenatal test), but the details were certainly of interest to the target audience on the SpecNOW site.
Of course, the mainstream media picked up on the news of the possibility [...]Post from: Sciencebase Science Blog... Read more »

Research suggests that a highly infectious virus might be behind some cases of obesity. There is constant talk of an epidemic of overweight in the developed world. Overindulgence, lack of exercise, sedentary lifestyles are usually blamed. Occasionally, the words genetics or glands are mentioned, but rarely is the obesity epidemic thought of as a disease [...]Post from: Sciencebase Science Blog... Read more »
