Long-lost records confirm rising sea level

The discovery of 160 year old records in the archives of the Royal Society, London, has given scientists further evidence that Australian sea levels are rising.

Observations taken at Tasmania’s Port Arthur convict settlement 160 years ago by an amateur meteorologist have been compared with data from a modern tide gauge.

“There is a rate of sea level rise of about 1mm a year, consistent with other Australian observations,” says Dr David Pugh, from the UK’s Southampton Ocean

Female Hormones Found To Protect Against Harmful Effects Of Fructose

Groundbreaking study in female mice links estrogen, lower blood pressure, and insulin resistance, despite a high fructose diet

Bethesda, MD – High-fructose corn syrup replaced sucrose (table sugar) as a sweetener in most grocery products some 20 years ago. Today, about nine percent of the average dietary energy intake in the U.S. comes from fructose. However, a number of nutritionists are alarmed by the amount of the public’s consumption, as previous research has demonstrated that a

Fighting against infections with beneficial bacteria

By using mouse models, the EU-funded DEPROHEALTH-project has demonstrated that some lactobacilli can have a beneficial effect on intestinal inflammation and infections. The major target disease in these mouse studies has been inflammation of the bowel. For this purpose, engineered lactobacilli were constructed. The modified strains that are most promising produce fair levels of an effective compound (an interleukine) that helps preventing the inflammation caused by bacteria. Four of the most promi

Researchers achieve germline transmission of ’gene knockdown’ in mice

RNA interference (RNAi) has emerged as an extremely versatile and powerful tool in biomedical research. A new study published in the February issue of Nature Structural Biology reports the creation of transgenic mice in which inherited RNAi lowers or silences the expression of a target gene, producing a stable “gene knockdown.” This finding extends the power of RNAi to genetic studies in live animals, and has far-reaching implications for the study and treatment of many human diseases.

University of Pittsburgh study finds carbon monoxide has therapeutic benefits

Exposing rats to low levels of carbon monoxide prevents arteriosclerosis and chronic organ rejection

Exposing rats to low levels of carbon monoxide (CO) prior to aorta transplantation prevents arteriosclerosis associated with chronic organ rejection and can also suppress stenosis after balloon-angioplasty-induced carotid artery injury, according to a study published in the Feb. 1 edition of Nature Medicine. The article is published online today.

“These findings demonstrate a

Researchers find a genetic connection in Sudden Infant Death Syndrome (SIDS)

Information could help identify at-risk individuals and estimate

Researchers at Rush-Presbyterian-St. Luke’s Medical Center have found evidence supporting a relationship between SIDS and the 5-HTT gene in both African-Americans and Caucasians. They found a significant positive association between SIDS and the L/L genotype, and between SIDS and the 5-HTT L allele, and a negative association between SIDS and the S/S genotype. This information might eventually lead to the identification
