University of Leicester researchers writing in the journal Chemical Research in Toxicology say they have found "convincing evidence" that cannabis smoke damages DNA and it could potentially increase the risk of cancer development in humans.
Using a newly developed highly sensitive liquid chromatography-tandem mass spectrometry method, the University of Leicester scientists say they have found clear indication that cannabis smoke damages DNA under laboratory conditions.
The researchers are Rajinder Singh, Jatinderpal Sandhu, Balvinder Kaur, Tina Juren, William P. Steward, Dan Segerback and Peter B. Farmer from the Cancer Biomarkers and Prevention Group, Department of Cancer Studies and Molecular Medicine and Karolinska Institute, Sweden.
An ancient Ice Age, once regarded as a brief 'blip', in fact lasted for 30 million years according to geologists at the University of Leicester who will discuss their findings during a public lecture at the University on Wednesday June 17.
Their research suggests that during this ancient Ice Age, global warming was curbed through the burial of organic carbon that eventually lead to the formation of oil – including the 'hot shales' of north Africa and Arabia which constitute the world's most productive oil source rock.
This ice age has been named 'the Early Palaeozoic Icehouse' by Dr Alex Page and his colleagues in a paper published as part of a collaborative Deep Time Climate project between the University of Leicester and British Geological Survey.
A new study says Tai Chi can have positive health benefits for musculoskeletal pain. The results of the first comprehensive analysis, conducted by The George Institute for International Health in Australia, suggests Tai Chi produces positive effects for improving pain and disability among arthritis sufferers.
An enormous eruption has found its way to Earth after travelling for many thousands of years across space. Studying this blast with ESA's XMM-Newton and Integral space observatories, astronomers have discovered a dead star belonging to a rare group: the magnetars.
X-Rays from the giant outburst arrived on Earth on 22 August 2008, and triggered an automatic sensor on the NASA-led, international Swift satellite. Just twelve hours later, XMM-Newton zeroed in and began to collect the radiation, allowing the most detailed spectral study of the decay of a magnetar outburst.
Autistics are up to 40 percent faster at problem-solving than non-autistics, according to a new Université de Montréal and Harvard University study published in Human Brain Mapping. As part of the investigation, participants were asked to complete patterns in the Raven's Standard Progressive Matrices (RSPM) test that measures hypothesis-testing, problem-solving and learning skills.
While autism is a common neurodevelopmental disability characterized by profound differences in information processing and analysis, this study showed that autistics have efficient reasoning abilities that build on their perceptual strengths.
In 1987, Robert Bork became the target of an organized, special interest smear campaign aimed at ruining his chances for being confirmed by the Senate as a Supreme Court justice. Since then, a tit-for-tat approach has made Supreme Court appointments a political football.
These politicized Supreme Court nomination battles have eroded public support of the high Court and a study of public reactions during the Samuel Alito nomination process shows it is only going to get worse.
In a new book, researchers reveal how television advertisements that opposed Alito's nomination in 2005 had a disturbing side effect: Many people who viewed those highly political ads become less supportive of the Supreme Court as an institution.

A completely new species has been discovered in the Russian mountains!
Sorry, it's not Bigfoot or Yeti or Abominable Snowman or Bumble or whatever he is called where you are from, though "Bigfoot Found!" on the cover with a big "No" inside would certainly be a strategy worthy of some other science publications.
Instead, it is a much more scientific discovery; a plant root. Professor Hans Cornelissen and his Russian-Dutch team describe this finding in Ecology Letters.
The root belongs to the small alpine plant Corydalis conorhiza and unlike normal roots, which grow into soil, they extend upward through layers of snow. Given this novel behavior, the scientists have termed them 'snow roots'.
We can measure what people prefer and value, but do we know why? And can we predict whether a nation will be liberal or conservative, atheist or religious, polygynous or monogamous?
While researching for a forthcoming article I stumbled upon a paper by Satoshi Kanazawa, an evolutionary psychologist at the London School of Economics, on the origin of individual values and preferences that indicate that the values of a nation are tied to its IQ.
The article, to be published in the July issue of Journal of Biosocial Science, is a quick read (despite being 20 pages long), and offers one possible explanation of why people have individual values and preferences: the Savanna-IQ Interaction Hypothesis.
