Massive study identifies 579 genomic locations linked to self-regulating behaviors

Researchers have identified 579 locations in the human genome associated with a predisposition to self-regulation-related behaviors, including addiction and child behavioral problems. With data from 1.5 million people of European descent, the effort is considered to be one of the largest genome-wide association studies to date.

Researchers show how the genetic material travels from cell to cell

The genetic material of plants, animals, and humans is well protected in the nucleus of each cell and stores all the information that forms an organism. For example, information about the size or color of flowers, hair or fur is predefined here.

Many light smokers meet the criteria for nicotine addiction

Even people who consider themselves to be casual cigarette smokers may be addicted, according to current diagnostic criteria. Researchers at Penn State College of Medicine and Duke University found that many light smokers -- those who smoke one to four cigarettes per day or fewer -- meet the criteria for nicotine addiction and should therefore be considered for treatment.

Researchers discover molecular mechanism of plant immune receptors

In a recent study, Alexander von Humboldt Professor Jijie Chai at the University of Cologne and his team together with MPIPZ researchers have succeeded for the first time in reconstructing the sequence of molecular events that activate an inactive plant immune receptor and thus mediate the death of the host cell.

Study reveals how bean plants initiate anti-herbivore defenses

For a caterpillar, a green leaf can make a nice meal. But to the plant itself, it's an attack. And very hungry caterpillars can do a lot of damage as they eat their way through life.

Cancer mutations occur in distinct patterns based on 3D structure of the genome

A new study from researchers at The University of Texas MD Anderson Cancer Center has discovered that mutations found in cancers do not accumulate randomly, but are found in distinct patterns that vary based on the three-dimensional organization of the genome in the cell as well as the underlying factors causing the mutations.

Study shows strigolactones enhance tolerance to insects in tobacco plants

A team of researchers at the Max Planck Institute for Chemical Ecology in Jena, Germany, has discovered that strigolactones, a class of novel plant hormones, mediate the fine-tuning of the production plant defensive substances in the stem of plants of the wild tobacco species Nicotiana attenuata.
