Ranking The Top 20 Science Sites

Recently we had a conversation about where we ranked among science sites. There are a few measurement services out there, and they all give different numbers ( none of which are truly accurate) plus they all seem to have their own method for determining 'reach' that goes beyond simple traffic.

We decided to compare all the science sites, including ones that are doing different things like articles, blogging and news releases, against each other, using the results from two traffic ranking services, one opt-in popularity service and one service that measures inbound links.

Iceland - Leading the World Towards a 100% Sustainable Energy Society

Iceland is the world's leading nation in utilising renewable energy. Its next aim is to tackle the transport industry. Renewable energy for vehicles and sustainable solutions for transport are the focus of Driving Sustainability '07 Conference (http://www.driving.is) held in Reykjavik on September 17-18.

Scientists Use the "Dark Web" to Snag Extremists and Terrorists Online

Terrorists and extremists have set up shop on the Internet, using it to recruit new members, spread propaganda and plan attacks across the world. The size and scope of these dark corners of the Web are vast and disturbing.

One sample examined by a thousand pathologists - how and why?

This week, more than eight hundred pathologists from around Europe and the world will take part in a first of its kind, large-scale virtual microscopy slide seminar on the web. The seminar is arranged by the Biomedical Informatics Research Group from the University of Helsinki in conjunction with the 21st European Congress of Pathology, which will be held in Istanbul, Turkey.

Bacteria from sponges make new pharmaceuticals

Thousands of interesting new compounds have been discovered inside the bodies of marine sponges according to scientists speaking today (Tuesday 4 September 2007) at the Society for General Microbiology’s 161st Meeting at the University of Edinburgh, UK, which runs from 3-6 September 2007.

Over half of the bodyweight of living sea sponges – including the sort that we use in our baths – is made up of the many different bacteria that live inside them, in the same way that we all have bacteria living in our guts which help us to digest our food.

Predicting volcanic eruptions

University of St Andrews scientists have been awarded a three year grant to create an on-site life-saving device to help predict volcano eruption.

The work is funded by nearly £400K from the Natural Environment Research Council (NERC), bringing the team's recent research funding to just over £1 million, following a £700K sub-contract from ERA Technology Limited for new work on military security.

Microbes in the tailoring of barley malt properties

Research Scientist Arja Laitila from VTT Technical Research Centre of Finland has investigated the impacts of bacterial and fungal communities on barley germination and on malt properties in her PhD thesis work. She will defend her thesis "Microbes in the tailoring of barley malt properties" at the University of Helsinki on 31 August 2007.Arja Laitila

World's Oldest Bacteria

A research team has for the first time ever discovered DNA from living bacteria that are more than half a million years old. Never before has traces of still living organisms that old been found. The exceptional discovery can lead to a better understanding of the ageing of cells and might even cast light on the question of life on Mars. The discovery is being published in the current issue of PNAS (Proceedings of The National Academy of Sciences of The United States of America).

Wrinkles On The Moon

Good lighting and high resolution cameras in the SMART-1 satellite are making it possible to put together the story linking geological and volcanic activity on the Moon.

“Thanks to low-elevation solar illumination on these high-resolution images”, says SMART-1 Project Scientist Bernard Foing, “it is now possible to study fine, small-scale geological features that went undetected earlier.”

Are civil unions a 600-year-old tradition?

Sharing '1 bread, 1 wine, and 1 purse': The history of brotherment.

A compelling new study from the September issue of the Journal of Modern History reviews historical evidence, including documents and gravesites, suggesting that homosexual civil unions may have existed six centuries ago in France. The article is the latest from the ongoing “Contemporary Issues in Historical Perspective” series, which explores the intersection between historical knowledge and current affairs.

New finding bubbles to surface, challenging old view

Chemical engineers have discovered a fundamental flaw in the conventional view of how liquids form bubbles that grow and turn into vapors, which takes place in everything from industrial processes to fizzing champagne.

The findings cast into doubt some aspects of a theory dating back to the 1920s that attempts to describe the underlying molecular mechanism behind a phenomenon called "homogeneous nucleation," said David S. Corti, an associate professor of chemical engineering at Purdue University.

Princeton scientists confirm long-held theory about source of sunshine

Scientists are a step closer to understanding sunshine. A monumental experiment buried deep beneath the mountains of Italy has provided Princeton physicists with a clearer understanding of the sun's heart -- and of a mysterious class of subatomic particles born there.

Biofuels CO2 Impact Is 9X That Of Petrol, Says World Land Trust

Researchers at the University of Leeds and the World Land Trust have warned that growing biofuel crops to make eco-friendly car fuel could actually be harmful to the environment.

Large areas of land in the developing world are being converted to grow crops such as sugar cane and palm oil as part of the global rush to make biofuels which are widely thought to produce less carbon dioxide than conventional transport fuels.

Plain soap as effective as antibacterial but without the risk

Antibacterial soaps show no health benefits over plain soaps and, in fact, may render some common antibiotics less effective, says a University of Michigan public health professor.

Keeping the Earth's plates oiled

Earth’s surface is a very active place; its plates are forever jiggling around, rearranging themselves into new configurations. Continents collide and mountains arise, oceans slide beneath continents and volcanoes spew. As far as we know Earth’s restless surface is unique to the planets in our solar system. So what is it that keeps Earth’s plates oiled and on the move?
