All the carbon counts
Cutting down forests for agriculture vents excess carbon dioxide into the air just as industrial activities and the burning of fossil fuels do. view more (2009-05-29)
Climate warming and habitat loss threaten British Butterfly survival
Because butterflies are cold blooded, their growth and development are closely dependent on the weather and climate. When climates change insects can either shift breeding distributions to track it, stay put and adapt, or die out. Since the 1970s, climate warming in Britain has seen almost 20% of butterflies spread their ranges northwards,... view more... (2003-06-05)
BMJ Publishing Group launches UK`s first `virtual journal`
To celebrate World Asthma Day on 7 May 2002, the BMJ Publishing Group has joined forces with the American Society of Pediatrics to launch Paediatric Asthma - the UK’s first virtual journal. view more (2002-04-30)
Study reveals mass migration of mormon crickets driven by hunger, fear
An international team of researchers, including Kent State University professor Dr. Patrick D. Lorch, have revealed the motivating factors behind the seasonal mass migration of Mormon crickets in western North America. view more (2006-03-03)
Small optical force can budge nanoscale objects
With a bit of leverage, Cornell researchers have used a very tiny beam of light with as little as 1 milliwatt of power to move a silicon structure up to 12 nanometers. That's enough to completely switch the optical properties of the structure from opaque to transparent, they reported. view more (2009-11-18)
Continents loss to oceans boosts staying power
New research suggests that the geological staying power of continents comes partly from their losing battle with the Earth's oceans over magnesium. view more (2008-04-02)
Tiny shock absorbers help bacteria stick around inside the body
Bacteria have hair-like protrusions with a sticky protein on the tip that lets them cling to surfaces. The coiled, bungee cord-like structure of the protrusions helps the bacteria hang on tightly, even under rough fluid flow inside the body. view more (2006-08-30)
Can email help doctors use their time more productively?
In almost every era doctors have perceived themselves as "running faster" but there is little evidence to support this. Doctors feel stressed because there is now so much more they can do. There are more external forces impinging on their practice and patients and the public have raised expectations, yet patients value meaningful time... view more... (2001-08-01)
LEGO toy helps researchers learn what happens on nanoscale
Johns Hopkins engineers are using a popular children's toy to visualize the behavior of particles, cells and molecules in environments too small to see with the naked eye. view more (2009-08-26)
UCLA scientists design new super-hard material
Ultra-hard materials are used for everything from drills that bore for oil and build new roads to scratch-resistant coatings for precision instruments and the face of your watch. view more (2007-04-23)
First diesel military motorcycle to hit the road
A unique technology partnership between Cranfield University and California-based Hayes Diversified Technologies (HDT) has created the world's first production diesel military motorbike - and the first bike of any kind with a purpose-designed diesel power unit. view more (2004-11-03)
Optimising the control of wind generators by means of intelligent microsensors
The School of Engineering at Bayonne (ESTIA) is working on a research project on control optimisation for the latest-generation wind generators using intelligent microsensors. view more (2006-04-25)
How Do Bacteria Swim? Brown Physicists Explain
Imagine yourself swimming in a pool: It's the movement of your arms and legs, not the viscosity of the water, that mostly dictates the speed and direction that you swim. view more (2008-11-20)
Evolution: fish select for the survival of teh fittest
An important breakthrough has been made in determining the forces responsible for the evolution of populations in nature. By studying wild populations of grayling (a close relative of salmon), Mikko Koskinen and Craig Primmer at the University of Helsinki and Thrond Haugen at the University of Oslo found that natural selection, a force suggested... view more...

Sudan - A War Against The People (p 161)
Two Health and Human Rights articles in this week's issue of THE LANCET highlight the ongoing and forgotten war in Sudan. Now two decades on, the health and wellbeing of the people of Sudan remains a major concern. In the first article, César Chelala discusses the impact of oil in the south of the country.
