Tolerance To Inhalants May Be Caused By Changes In Gene Expression
Changes in the expression of genes may be the reason why people who abuse inhalants, such as spray paint or glue, quickly develop a tolerance, biologists have discovered. This is the first study to show that a single drug experience alters the response of an animal to future doses by epigenetically modifying a single gene. Lower-cost Solar Cells To Be Printed Like Newspaper, Painted On Roofto
Solar cells could soon be produced more cheaply using nanoparticle "inks" that allow them to be printed like newspaper or painted onto the sides of buildings or rooftops to absorb electricity-producing sunlight. Detecting Brain Infections Without Surgery
Researchers at Westmead Millennium Institute have discovered a safe, non-surgical method of identifying brain infections such as brain abscess, and an accurate and rapid way of diagnosing meningitis. The Roman Curia: Congregations: Congregation for the Doctrine of the F
Information from the Vatican about this group "founded in 1542 by Pope Paul III ... [which] was originally called the Sacred Congregation of the Universal Inquisition as its duty was to defend the Church from heresy. It is the oldest of the Curia's nine congregations."Includes a brief profile, doctrinal and disciplinary documents, and related material, some of which are by Cardinal Joseph Ratzinger (now Pope Benedict XVI). Many of the documents are available in several languages (some not in English). Older Adults May Be Unreliable Eyewitnesses, Study Shows
A University of Virginia study suggests that older adults are not only more inclined than younger adults to make errors in recollecting details that have been suggested to them, but are also more likely than younger people to have a very high level of confidence in their recollections, even when wrong. The finding has implications regarding the reliability of older persons' eyewitness testimonies in courtrooms. Bioluminescence Genes Found Through Metagenomic Study Of Deep Mediterr
Metagenomics is a revolutionary approach to study microbes. Rather than isolating pure cultures, the power of high-throughput sequencing is applied directly to environmental samples to obtain information about the genomes of the prokaryotic cells present in a specific habitat studied. A recent analysis of a metagenomic library from the deep Mediterranean shows a surprising high number of quorum sensing or lux genes that are only expressed when bacteria live in colonies. The deep ocean might be too depleted in resources for microbes to live independently. Some of the genes detected have been identified as directly involved in bioluminescence. Lessons Learned From Liver Retransplantation
A new study on liver retransplantation (re-LT) over a 15 year period at a clinic in Germany found that indications for the surgery had changed and there were fewer rejections, complications, and recurrence of disease during that time. The positive trend may be due to improvements in intensive care management and immunosuppressants, along with early decisions about when to retransplant despite the shortage of quality donor organs. Therapy To Overcome Fears Helps Children With Obsessive-compulsive Dis
Psychological treatment that teaches children to face their fears is the most effective treatment for pediatric obsessive-compulsive disorder (OCD), according to a new Mayo Clinic analysis of previously published research. Molecular Thermometers On Skin Cells Detect Heat And Camphor
The human brain is like a general in a bunker. Floating in its bubble of cerebrospinal fluid, it has no direct window to the outside world, so the only way for the brain to observe, comprehend, and order the body into action is to rely on information it receives. This information comes to it through a sophisticated system of sensory neurons that connect the brain to organs like the eye, ear, nose, and mouth.
