Toward a long-sought saliva test for autism

Over the past decade, research in the field of epigenetics has revealed that chemically modified bases are abundant components of the human genome and has forced us to abandon the notion we've had since high school genetics ...

UCLA scientists have created a mouse model for autism that opens a window into the biological mechanisms that underlie the disease and offers a promising way to test new treatment approaches.

Embargoed by the journal Neuron until February 9, 2011, noon, Eastern time – A study from The Scripps Research Institute has unveiled a surprising mechanism that controls brain formation. The findings have implications ...

Scientists in the Hotchkiss Brain Institute at the Faculty of Medicine, University of Calgary, have discovered a new mechanism that nerve cells (neurons) use to fine-tune their electrical output. The exciting discovery, published ...

For years, the majority of research on reactive oxygen species (ROS) – ions or very small molecules that include free radicals – has focused on how they damage cell structure and their potential link to stroke, ...

UCLA scientists have discovered that exposing fetal neurons to higher than normal levels of a common immune protein leads to abnormal brain development in mice.

There was chaos on the streets of Halajba in March 1988. In this corner of Iraq, at the time Iraqi Kurdistan, people had suddenly started experiencing cold-like symptoms – tight chest and nasal congestion. ...

(Phys.org) —Using only biomolecules (such as DNA and enzymes), scientists at the Technion-Israel Institute of Technology have developed and constructed an advanced biological transducer, a computing machine capable of manipulating ...

Bacteria can move electrons at least half a millimeter across a scaffolding made by themselves, of themselves, even under starving conditions. This new finding by EMSL staff and users challenges conventional ...

(Phys.org) —In humans, a polymer called melanin determines skin, eye and hair color—the darker the skin, the more melanin in a person's body. For insects, melanin is a major aspect of their immune defense ...

(Phys.org) —How our bodies break down the common drugs ibuprofen, diclofenac and warfarin is the subject of a new study from the University of Bristol, published in the Journal of the American Chemical So ...

(Phys.org) —Ammonia must overcome an energy barrier to join sulfuric acid and water to create clusters that can lead to cloud formation, according to scientists at Pacific Northwest National Laboratory ...
