Briefing: Cannabis compounds fight prostate cancer - health - 19 August 2009 - New Scientist
"Compounds similar to those found in cannabis have been shown to stop prostate cancer cells from multiplying. Two cannabinoid compounds, JWH-015 and MET, stopped prostate tumour growth in human prostate cells in Petri dishes and also in mice with the disease. They halted the cell-division cycle and killed the cancer cells, and had the greatest effect on aggressive prostate cancer cell types, which do not respond to hormone treatments.
Some 192,000 men in the US alone are diagnosed with prostate cancer each year, and researchers Inés Díaz-Laviada Marturet at the University of Alcalá, Spain, and her colleagues say the results could offer hope to those affected. But before you go looking for a dealer, New Scientist answers a few questions"

Evolution - New Scientist
Evolution is the unifying force in modern biology, but it remains a source of misunderstanding and controversy. Start finding out why it is so important with our beginner's guide
Timeline: The evolution of life - life - 14 July 2009 - New Scientist
There are all sorts of ways to reconstruct the history of life on Earth. Pinning down when specific events occurred is often tricky, though. For this, biologists depend mainly on dating the rocks in which fossils are found, and by looking at the "molecular clocks" in the DNA of living organisms.
There are problems with each of these methods. The fossil record is like a movie with most of the frames cut out. Because it is so incomplete, it can be difficult to establish exactly when particular evolutionary changes happened
How to unleash your brain's inner genius - life - 03 June 2009 - New Scientist
Savants - individuals with conditions that result in remarkable mathematical, artistic or musical talents - are extremely rare. But new findings about how their formidable brains work hint that we might all be able to develop similar abilities
What you should know about chiropractic - opinion - 29 May 2009 - New Scientist
FOR many people, chiropractic appears almost mainstream. Some chiropractors even call themselves "doctor". In the UK, chiropractors are regulated by statute, and in the US they like to be seen as primary care physicians. It is therefore understandable if people hardly ever question the evidential basis on which this profession rests.
A Facebook profile can reveal the real you - tech - 26 May 2009 - New Scientist
Judging a book by its cover may be unwise, but online profiles are fair game, new research suggests. University students considered likeable by people that met them in real life have been found to make a similar impression on people who view their Facebook profiles.
"People who were expressive in tone of voice and facial expression were also socially expressive on Facebook. They posted a lot of pictures, they posted photo albums, they seemed to have a lot of conversations with people," says Max Weisbuch, a psychologist at Tufts University in Medford, Massachusetts who led the study.
Born believers: How your brain creates God - science-in-society - 04 February 2009 - New Scientist
That's not to say that the human brain has a "god module" in the same way that it has a language module that evolved specifically for acquiring language. Rather, some of the unique cognitive capacities that have made us so successful as a species also work together to create a tendency for supernatural thinking. "There's now a lot of evidence that some of the foundations for our religious beliefs are hard-wired," says Bloom.
New cosmic map reveals colossal structures - space - 04 April 2009 - New Scientist
Enormous cosmic voids and giant concentrations of matter have been observed in a new galaxy survey, one of the biggest completed so far. One of the voids is so large that it is difficult to explain where it came from.

In 2000, Brigitte Senut discovered the remains of the first human ancestor known to have walked upright. She told Laura Spinney about fossil-hunting in Africa
Climate changes Europe's borders - and the world's - environment - 27 March 2009 - New Scientist
Italy and Switzerland are planning to redraw their shared alpine border, as global warming is melting the glaciers that originally guided the line. Although peaceful, the move raises fears of future conflicts over shifting borders and resources.
Glaciers and ice fields around the world are melting as temperatures rise, with Europe's high mountains particularly hard hit.
The original proposal to move the Swiss-Italian border comes from Franco Narducci, a member of Italy's centre-left opposition party.
Cannabis compound slows lung cancer in mice - health - 18 April 2007 - New Scientist
The active compound in marijuana, THC, can slow the growth of lung tumours and reduce the spread of the cancer in mice, a preliminary study reveals.
Human lung cancer tumours grew less than half as fast in mice that received moderate doses of the compound, the researchers reveal. They hope that drugs mimicking the apparent anti-cancer effects of tetrahydrocanabinol (THC) could one day help treat patients. The team strongly discourage people from self-medicating by smoking marijuana, noting that doing so could potentially encourage tumour growth.
Eating less meat could cut climate costs - environment - 10 February 2009 - New Scientist
Cutting back on beefburgers and bacon could wipe $20 trillion off the cost of fighting climate change. That's the dramatic conclusion of a study that totted up the economic costs of modern meat-heavy diets.
The researchers involved say that reducing our intake of beef and pork would lead to the creation of a huge new carbon sink, as vegetation would thrive on unused farmland.
Nuclear rockets could cut cost of Moon base - space - 28 June 2007 - New Scientist Space
Nuclear-powered rockets could save NASA billions of dollars in launch costs for its planned return to the Moon, a top nuclear scientist says. He argues that the higher efficiency of nuclear propulsion would reduce the number of launches needed to build a
Herbal remedy forskolin could flush out bladder infections - health - 08 April 2007 - New Scientist
An herbal extract used by bodybuilders can help clear the bladder of infectious bacteria, according to a new mouse study. Researchers say people may one day be able to use the extract, known as forskolin, in combination with antibiotics to prevent urinary
