The end of drug discovery? 21 May 2012Last updated at 20:32 ET By Smitha Mundasad BBC Radio 4 Will we find new cures for the 21st Century?
Half a century ago, in the drug industry's golden era, we were bestowed with countless pills to lower blood pressure, control blood sugar and get rid of infections. But today it costs about $1bn to bring a new medicine to market, a process that can take 15 years. The industry faces multiple crises as budgets are squeezed and tough scientific challenges loom. Academics and patients' groups are concerned we will not have the drugs necessary to treat future ills. Last year, the World Health Organization's director general, Margaret Chan, warned that the world was heading for a "post-antibiotic era".
She raised fears that many common infections might no longer have a cure and could once again "kill unabated". Major problems, Dr Chan suggested, included growing resistance to antibiotics. 'Inefficient model' But the old model of drug discovery is no longer working well. How Life Begins in the Deep Ocean - YouTube.

The UN predicts the world's population explosion: visualised. When analogies go bad. Lots has been written about the scientific method (and even I have written about it in a minor way in the past).
The cycle of “make hypothesis, make predictions, test predictions, revise hypothesis, repeat” is the main thing people focus on when talking about how scientific progress happens. What’s less talked about is where the hypothesis comes from in the first place, which starts with someone (maybe you, dear reader) noticing something that needs to be explained. Welcome. What is the difference between a buffalo and a bison?* The question of how a genotype (the arrangement of letters in DNA) maps to a phenotype (the shape and behavior of an organism) can be examined at many levels.
On the one hand, we’d like to know how small differences in DNA sequence determine differences between individual humans, such as susceptibility to disease, height, IQ, maybe musical talent… the list is long. On the other hand, we’d like to know which DNA differences determine the crucial differences between species. What makes the beak short or long or pointy, what makes the neck short or long, what determines the size of the average member of the species? Carbonnation - The Movie. Energy Information. We launched Google PowerMeter as a free energy monitoring tool to raise awareness about the importance of giving people access to their energy information.
PowerMeter included key features like visualizations of your energy usage, the ability share information with others, and personalized recommendations to save energy. We partnered with device manufacturers and utilities around the world. Many of our partners now have new options available for accessing energy information. We are pleased that PowerMeter helped demonstrate the importance of access to energy information, and created a model for others.
We retired the service on September 16, 2011. We continue to see encouraging results about the importance of access to energy data. Momentum is building toward making energy information more readily accessible, and it’s exciting to see others drive innovation and pursue opportunities in this important new market.

Photo: tonx (flickr) How many times could you recycle a single sheet of paper before the fibers got too short and weak to hold together? You’ve seen the recycling logo, three arrows pointing around in an endless loop. This is a little misleading though, because you just can’t recycle the same piece of paper endlessly. A sheet of paper is made of interlocking fibers, which originally started out as wood fibers suspended in water, a mixture known as pulp. HOME - Ecological Footprint - Ecological Sustainability. Earth Overshoot Day. In 8 Months, Humanity Exhausts Earth's Budget for the Year August 20 is Earth Overshoot Day 2013, marking the date when humanity exhausted nature’s budget for the year.
We are now operating in overdraft. For the rest of the year, we will maintain our ecological deficit by drawing down local resource stocks and accumulating carbon dioxide in the atmosphere. Just as a bank statement tracks income against expenditures, Global Footprint Network measures humanity’s demand for and supply of natural resources and ecological services.
