Towards improved immunotherapy

A study published in Clinical Immunology describes a new method to induce regulatory T cells, which show great potential for treating autoimmune diseases and improving transplant outcomes. The method uses an inexpensive and simple high-yield approach to generate large amounts of these immune suppressive cells.

Drivers distracted more by cell phones than by passengers

A new study by University of Utah psychologists found that drivers are more distracted by talking on a cellular phone than by conversing with a passenger in an automobile. When drivers talk on a cell phone, they drift out of their lanes and missed exits more frequently than drivers conversing with a passenger.

Pseudoephedrine use common among young children

A study found that pseudoephedrine use is prevalent among US children, especially those under two years old, with 4.9% of all children taking it weekly and 8.1% of those under two taking it in a given week. The study also identified patterns of use, including taking multiple products at once and using it for long periods.

No place like home: New theory for how salmon, sea turtles find their birthplace

Marine biologists propose that animals learn the unique magnetic signature of their home area early in life and retain it to navigate back to their birthplace for reproduction. The theory suggests that magnetic imprinting helps animals distinguish their home location from others, allowing them to return years later.

Sex life of killer fungus finally revealed

Biologists have discovered a sexual cycle in the deadly fungus Aspergillus fumigatus, revealing its ability to adapt to new environments and evade antifungal drugs. This breakthrough could lead to new treatments for patients infected with the fungus, which causes severe asthma and immune deficiency-related deaths.

New treatment hope for people with recurring depression

A study published in the Journal of Consulting and Clinical Psychology shows that Mindfulness Based Cognitive Therapy (MBCT) is as effective as anti-depressant medication in preventing relapse and enhancing quality of life for people with long-term depression. The study found that MBCT provides a cost-effective alternative to prescript...

Cell movements totally modular, Stanford study shows

Researchers at Stanford University School of Medicine have shown that distinct groups of proteins each control one of four simple activities involved in the cells' collective migration. The study overturns an assumption common in genomics and provides a powerful tool for developing new therapeutics.

Protection from the own immune system

Researchers at Heidelberg University Hospital developed a vaccine that prevents multiple sclerosis in mice by suppressing the harmful immune response. The treatment uses autologous immune cells treated with mitomycin and expresses a self-protein from the nervous system, rendering them non-reactive to the disease.

AGU journal highlights: Nov. 28, 2008

Research published in AGU journals reveals a significant decrease in Saharan dust due to increased rainfall, boosting ocean heating. The coastal Southern Ocean also acts as a powerful carbon sink, with Antarctic shelf waters showing high biological productivity and extensive winter sea ice cover.

Selenium may slow march of AIDS

Researchers at Penn State have discovered that increasing selenium levels in human blood cells can reduce the multiplication of the AIDS virus. By targeting a specific protein called Tat, selenium can slow down viral replication, with results showing a 10-fold decrease.

A new light on work-related fatigue

Research found that workers with high levels of alanine aminotransferase (ALT) and central obesity had significantly higher self-reported fatigue after work. The study suggests that objective measures such as elevated ALT and increased waist circumference are associated with work-related fatigue in apparently healthy workers.
