Post-copulatory sexual selection and sexual c... 
   
 
Abstract    
Male pregnancy in seahorses, pipefishes and sea dragons (family Syngnathidae) represents a striking reproductive adaptation that has shaped the evolution of behaviour and morphology in this group of fishes1. In many syngnathid species, males brood their offspring in a specialized pouch, which presumably evolved to facilitate male parental care5, 6. However, an unexplored possibility is that brood pouch evolution was partly shaped by parent–offspring or sexual conflict, processes that would result in trade-offs between current and future pregnancies. Here we report a controlled breeding experiment using the sexually dimorphic Gulf pipefish, Syngnathus scovelli, to test for post-copulatory sexual selection within broods and for trade-offs between successive male pregnancies as functions of female attractiveness. Offspring survivorship within a pregnancy was affected by the size of a male’s mate, the number of eggs transferred and the male’s sexual responsiveness. Significantly, we also found that embryo survivorship in a current pregnancy was negatively related to survivorship in the prior pregnancy, clearly demonstrating fitness trade-offs between broods. Overall, our data indicate that post-copulatory sexual selection and sexual c...

Abstract    

Micro and nanotechnologies are revolutionising medicine 'Almost invisible' tools are being developed by European researchers to discover diseases earlier and to treat patients better. The miniaturisation of instruments to micro and nano dimensions promises to make our future lives safer and cleaner. A team of European researchers from the Fraunhofer Institute for Biomedical Technologies Institute near Saarbruecken is using nanotechnology to improve diagnostic capabilities. In the "Adonis"-project, nano-sized gold particles are used to detect prostate cancer cells at an early stage.

Title          
Microeconomics for MBAs 
   
 
Abstract    
This is the first textbook in microeconomics written exclusively for MBA students. McKenzie/Lee minimizes attention to mathematics and maximizes attention to intuitive economic thinking. The text is structured clearly and accessibly: Part I of each chapter outlines the basic theory and Part II applies this basic theory to management issues. 'Perspective' sections in each chapter provide a new line of argument or different take on a business or policy issue, and carefully chosen topics and review questions are designed to spark lively and instructive debates. The accompanying DVD contains modules of Professor McKenzie talking informally with students, and elucidates complex lines of argument as well as acting as a revision aid. Throughout the book, McKenzie and Lee aim to infuse students with the economic way of thinking in the context of a host of problems that MBA students, as future managers of real-world firms, will find relevant to their career goals. http://books.google.com/books?id=-DdNTnRYmiIC&dq=microeconomics+for+mbas&psp=1

Title          
Sound, Vision & Nanoscience 
   
 
Abstract    
Scientists at the University of Bristol are turning to nature in their attempts to further their research into Nano-science.

Nano-science is the study of structures and properties at the nano-metre scale - a millionth of a millimetre - and the principle research tool is the Atomic Force Microscope. By looking at the ways in which insects "hear" very faint vibrations, the researchers at Bristol have been able to apply these techniques to Atomic Force Microscopes, significantly improving the sensitivity of these instruments, making it possible to record molecular structure with increased accuracy.

And at the nearby University of Bath they're applying Nano-science to investigate new lighting technology which could recreate natural sunlight in offices and homes, potentially saving billions on energy bills. Known as Solid State Lighting, researchers now estimate that in the next 20 years 90 per cent of the world's lighting will be provided by this technology.

Nano-science may be about the smallest things but its impact on our future will be very great indeed.

Title          
Drug Delivery - The Skin's the Thing! 
   
 
Abstract    
As the American comedian, Alan Sherman, observed in one of his songs -
"You gotta have skin,
All you really need is skin
Skin's the thing that if you've got it outside
It helps keep your insides in"....
But it's by no means an impenetrable barrier. Injections are the most common means of delivering drugs or taking samples from the body -- pushing a needle through the skin. It's invasive and painful and the majority of patients would rather avoid it.
Now researchers at the University of Bath are working on a variety of means of delivering drugs through the skin without having to puncture large holes in it.
Approaches such as the process of iontophoresis, pioneered by the University's Professor Guy, where a small electric current applied to the skin, through a device worn by the patient, can help therapeutic drugs cross the skin into the body.
Reverse iontophoresis also allows samples to be taken from the body and has been put to use in the Glucowatch which is helping diabetics in the US keep track of their glucose levels throughout the day without the need for routine 'finger stick' samples to be taken.
At the nearby University of Bristol, new approaches to delivering d...

Title          
CO2 emissions and climate change 
   
 
Abstract    
Global warming is the increase in the average temperature of the Earth's near-surface air and oceans in recent decades and its projected continuation. The global average air temperature near the Earth's surface rose 0.74 ± 0.18 °C (1.33 ± 0.32 °F) during the 100 year period ending in 2005.[1] The Intergovernmental Panel on Climate Change (IPCC) concludes "most of the observed increase in globally averaged temperatures since the mid-20th century is very likely due to the observed increase in anthropogenic greenhouse gas concentrations"[1] via the greenhouse effect. Natural phenomena such as solar variation combined with volcanoes probably had a small warming effect from pre-industrial times to 1950 and a small cooling effect from 1950 onward.[2][3] These basic conclusions have been endorsed by at least 30 scientific societies and academies of science,[4] including all of the national academies of science of the major industrialized countries.[5][6][7] While individual scientists have voiced disagreement with the conclusions of the IPCC[8], the overwhelming majority of scientists working on climate change are in agreement with the conclusions.
